Opis:: Zeolite has been successfully synthesized from clay and rice husk ash in the form of powder by using the hydrothermal method with variations in chemical compositions of alkaline solution and the amount of rice husk ash. The clay raw material was obtained from the Sidrap area of South Sulawesi and rice husk ash is obtained from the burning pile of rice husks. Sidrap clay and rice husk ash were activated using an alkaline solution of NaOH and varied rice husk ash and the addition of AlCl3. The addition of AlCl3, an alkaline solution of NaOH and H2O was used in the amount of 25.5 grams and variations of rice husk ash were 2.5 grams and 6.5 grams. Meanwhile, without the addition of AlCl3, an alkaline solution of NaOH and H2O was used for 20.5 grams and variations of rice husk ash from 2.5 grams and 6.5 grams. Then the mixture was then put into an autoclave with a temperature of 100°C for 3 hours. The basic material used in the manufacture of zeolite is carried out by X-ray Fluorescence (XRF) characterization to determine the constituent elements of basic material, which showed the content of SiO2 was 45.80 wt% in the clay and 93.40% in the rice husk ash. The crystalline structure of the zeolite formed was characterized by X-Ray Diffraction (XRD). It was found the resulting zeolite were identified as Zeolite-Y, Hydrosodalite, and ZSM-5. The microstructure properties of the resulting zeolite were determined by using Scanning Electron Microscopy (SEM).

Surface morphology
Opis:: Natural fibrous materials have been studied to address noise and high heat indices, but many of the existing studies about natural fibers do not sufficiently support their claims of better acoustical and heat insulating materials. Thus, this study investigated the surface morphology of easily available agricultural materials such as coconut husks, banana pseudostem and sugarcane husk for their potential as sound absorbers and thermal insulators. Fiber pads from the materials were constructed and analyzed for noise reduction coefficients, thermal insulating performance, water absorbing capacity and flame tolerance - using the methods specified in the American Society for Testing Materials. Herein, scanning electron microscopy (SEM) was applied for analytical imaging of the agricultural materials. Noise reduction coefficients (0.80 dB and 0.92 dB), (0.75d B and 0.78 dB) and (0.50 dB and 0.35 dB) each at 800 Hz and 440 Hz, and heat reductions of 2.56 °C, 1.71 °C, and 1.24 °C were obtained from coconut husk, sugarcane husk and banana pseudostem, respectively. The coconut husk also gave the highest water absorbing capacity and high flame tolerance of 56%, compared to that of sugarcane husk (49%) and banana pseudostem (32.67%). The morphology of the coconut husk, after SEM application revealed more diverse microporous cells with varying shapes and sizes compared to that of sugarcane husk and banana pseudostem. Thus, results indicate that porosity affects the noise and heat reduction indices of the fibers. The more porous the material is, the better its potential as sound absorber and thermal insulator.

Opis:: The present work is aimed at investigating the capability of chemically modified rice husks (MRH) for the reduction of aniline ions from industrial wastewater. The experiments have been conducted to examine the influence of four operating parameters in the batch adsorption technique. The effect of initial concentrations of aniline (10–100) mg•L-1, MRH dose (0.1–1) g/100 ml, pH (3–9), and contact time (10–90) min has been studied. The selected range of operating factors was designed using the response surface method to establish a mathematical model that describes the adsorption process. The optimum parameters were 25 mg•L-1 initial concentration of aniline, 0.68 g MRH dose, 6.6 pH, and 70 min contact time. The point of zero charge was found equal to 6.8. The maximum removal efficiency of 84.97% was found under optimum conditions. The consistency of the mathematical model has been examined and the equilibrium results confirmed with the standard adsorption isotherm models, Langmuir and Freundlich, with a high correlation coefficient.

Opis:: The continuous system of lead adsorption on rice husks was investigated in this paper. A fixed bed study was performed in many tests to investigate the influence of pH, the adsorbent height, the initial concentration of lead, the flow rate and processing time on the lead adsorption process. The results demonstrated that the lead removal capacity decreased when the pH value of the solution and the flow rate increased. The lead removal capacity increased due to the decreased initial concentration of lead. The results showed that the removal capacity increases along with the processing time and the adsorbent height in column. The largest removal was (81%) at pH of 4, the adsorbent height (50 cm), the initial concentration of lead (10 mg/l), the processing time (90 min.) and the flow rate (10 ml/min.). As a result, rice husks can be used to remove the lead instead of expensive commercial adsorbents, due to its availability, inexpensive and perfect adsorption property.

Opis:: The wastewater from the jewellery industry generally contains a large amount of metal. Metal removal can be done with many techniques, including precipitation and adsorption. Precipitation is done to convert the metal content from the dissolved phase to a solid that is easily precipitated. Generally, precipitation is unable to separate one hundred percent of metal content, so further processing is needed, i.e. adsorption. This research was done by using rice husk which is an agricultural waste in Indonesia. The rice husk is burnt to charcoal, then activated with acid. A SEM-EDX analysis was conducted to obtain a surface description of rice husk charcoal before and after use in the adsorption process. The results showed that the copper content in the jewellery wastewater can be adsorbed with a 40-50 mesh rice husk charcoal and the adsorption process follows the Freundlich isotherm model with R2 value of 0.9625.

Opis:: We investigated the efficiency of maize biomass parts - seed chaff, stalk, cob and husk, in the remediation of Cu2+ ion polluted water in modeled solutions. The adsorption capacity of these parts followed the order of husk > stalk > cob > seed chaff, with values of 9.65 mg/g, 4.83 mg/g, 3.70 mg/g and 2.48 mg/g, respectively. Maximum adsorption capacity of each part was reached in 45 min. Herein, the husk giving the best removal efficiency of 80.80%. Characterization of the maize husk using PIXE showed that potassium is the main cation on this biomass, with concentration 5.602 g/kg. FTIR scans of the husk before and after adsorption of Cu2+ ions gave shifts in adsorption bands on -OH carrying molecules, indicating that complexation is a mechanism in the metal ion removal process. The multi porous structure of the husk, and uniform surface coverage by ions observed from SEM images before and after adsorption, shed more light on the high adsorption efficiency shown by this natural waste material.

Opis:: The management of smallholder coffee plantations in Bengkulu Province has not yet conducted according to good agricultural practices. As a result, the productivity and quality of green beans produced are also low. The efforts to improve this condition need to be made in order to maintain the economic, social, and environmental sustainability of this agribusiness. The present study aimed at identifying the life cycle of the coffee agroindustry in supporting sustainable agriculture using the Life Cycle Assessment (LCA) method. The results of the study revealed that the energy input from the use of fertilizers, herbicides, manpower, and fossil fuel was 4349.08 MJ/ha. The energy output from the green beans and coffee husks was 9763.39 MJ/ha and 13524.21 MJ/ha, respectively, so the efficiency based on the input-output ratio was 5.35. The emission values to the global warming potential, acidification, and eutrophication were 109.43 kg eqCO2 , 345.70 g SO2 eq/ha/year, and 28.54 g PO4 3-eq/ha/year, respectively. The coffee agribusiness in Kepahiang Regency is categorized as organic. The coffee agribusiness was economically feasible with a Net B/C of 2.87, but the land ownership which was 1.45 ha/household and the present agribusiness conditions indicate a low sustainability rate.

Opis:: For this study, an electro kinetic method used to eliminate cadmium from the polluted soil. This method is useful at low permeability medium. Several experiments were conducted with variable operating circumstances, using different pH purging solutions. Rice husks were used in this work as an adsorbent medium available and free of charge to counteract the reverse osmosis process that occurs and affects the work efficiency. The final results after the end of the practical experiments of this process showed that the percentages of the removal process began to increase after the pH gradually decreases. The pH of the solution for the three experiments conducted was 3, 6 and 9, respectively. The best removal rate was 68% in this process at pH 3 ; when compared with the second and third tests at pH 6 and 9, the removal ratios were 58% and 51.5%, respectively. It was discovered that the cadmium removal rate began to decrease along with voltage. At 30 volts the removal rates were 68%, whereas 20 volts they were 66%. Rice husks have been shown to be an effective adsorbent for counteracting reverse osmosis. Therefore, it can be successfully used as an adsorbent medium.

Opis:: This study was concerned with the feasibility of using sunflower seed husk (waste material from the food industry) as a low-cost and available sorbent material to remove copper and lead ions. Sunflower seed husk was used for the biosorption of heavy metal ions (Pb(II) and Cu(II)) from aqueous solutions. The properties of natural adsorbent were characterized using Fourier transform infrared spectroscopy (FTIR). Pb(II) and Cu(II) adsorption were investigated in batch experiments through several influencing operating parameters, including contact time, sorbent dosage, initial pH, and initial concentration. The Pseudo-first-order and pseudo-second-order models were also applied to the experimental data to determine the adsorption kinetics. The results showed that adsorption of both ions fitted well by pseudo-Second-order, with determination coefficient R2 = 0.99, for both ions with SSE (1.628, 1.345) for Pb(II) and Cu(II), respectively.

Opis:: In this study, the shrimp shell-derived chitosan was coated onto rice husk-derived biochar to form chitosan/biochar bio-composite beads. The physicochemical properties of biochar (BC) and chitosan/biochar beads (CS@BC) were characterized by BET, SEM-EDX, FTIR, and pHpzc analyses, which were then tested for their capacity to remove Safranin O (SO) from water. In kinetics, the pseudo-second-order model was found to well represent experimental data, indicating the adsorption was mainly a chemical process. The intra-particle diffusion model was not the sole rate-limiting step, because the results did not pass through the origin. In isotherms, both the Langmuir and Freundlich models described well the equilibrium adsorption data. The CS@BC adsorbent showed adsorption capacity at 77.94 mg/g for SO, which is higher than BC adsorbent with 62.25 mg/g (experimental conditions: pH ~ 7.0, dosage = 0.2 g, contact time = 240 min, and temperature = 298 K). The findings revealed that the biochar-loaded chitosan can improve the adsorption capacity of SO. It is predicted that the enhancement in the functional groups (i.e., -NH2 and -OH groups) of CS@BC could contribute to the electrostatic interactions and the complexation between SO and CS@BC, thereby enhancing the Safranin O adsorption from water.

Opis:: Objectives: Electricity generation from biomass has become a boom business. However, currently, concerns over their environmental and health impact have emerged. This study aimed to explore these health problems by studying two small biomass power plants in Thailand. Materials and Methods: Data concerning chronic diseases and health symptoms was collected from 392 people by trained interviewers by the use of a questionnaire. Results: Residents living within 1 km from the power plants had a higher prevalence of allergies (Odds ratio = 2.4, 95% CI: 1.5-4.0), asthma (OR = 2.1, 95% CI: 1.0-4.4) and chronic obstructive pulmonary disease (COPD) (OR = 2.7, 95% CI: 1.0-8.4). The risks of other symptoms, itching/rash, eye irritation, cough, stuffy nose, allergic symptoms, sore throat, and difficulty breathing among those living within 0.5 km from the power plants (OR = 2.5-8.5) were even more marked. Conclusions: It has been concluded that without a proper control, pollution from the biomass power plants can cause significant health problems to the nearby residents.

Opis:: This work aimed to observe the influence of calorific value and proximate properties in the fabrication of rice husk (RH) and coffee shell (CS) briquettes composite. Rice and coffee husks contain cellulose, hemicellulose, and lignin. These contents are necessary for the adhesive to bind the briquette (amylose and amylopectin). The raw materials were carbonized at 400 °C for 60 minutes. Variations of sieving size (60, 80, and 100 mesh) and the composition ratio of raw material CS:RH were reviewed to study their effect. Tests of density, moisture content, volatile matter content, ash content, fixed carbon content, shatter index, combustion rate, and calorific value were carried out to determine the optimum composition. The results were obtained with the best quality at a particle size of 60 mesh with the highest calorific value of 17.422 MJ/kg. It showed that the briquettes have good quality and are comparable with the standard briquette.

Opis:: The availability of increasingly scarce fossil fuels causes high fuel prices, so alternative fuels are needed to reduce the use of fossil energy. Briquettes are an alternative energy that can be made from biomass, one of which is rice husk. The quality of the briquettes was determined by the material, the type of adhesive, and the strength of the briquette pressure. The briquette pressure will affect the mechanical properties of the briquettes such as density, stability and durability of the briquettes. This study aimed to determine the features of rice husk charcoal briquettes with variations in compacting pressure as an alternative fuel. The compaction pressure used in this study was 3 tons, 5 tons, and 7 tons. In general, the briquettes produced from this study can be used as an alternative energy source in terms of the resulting combustion temperature which ranges from more than 300–500 °C.The combustion rate obtained shows that the briquettes with a compaction pressure of 3 tons have a high combustion rate value of 0.553 g/minute, while the briquettes with a compaction pressure of 5 tons and 7 tons have a low combustion rate value of 4.20 g/min and 0.418 g/minute respectively. Therefore, the best quality briquettes from this study were the briquettes with a compaction pressure of 5 tons and 7 tons, so that they could be considered as alternative energy for wood and fossil fuels for energy needs in the domestic industry.

Opis:: This paper presents the outcome of a research study aimed at the performance evaluation of rice husk ash as partial replacement of cement in sandcrete blocks used as masonry units. Rice husk from rice cultivated in the North of Pakistan was used in the study. It was first combusted in a locally manufactured incinerator to convert it into rice husk ash (RHA) and then finely ground to powder form for use with cement. Blocks of size 305 mm×203 mm×152 mm were molded with 0, 10, 30, 40 and 50 % replacement of cement with RHA to find compressive strength at 3, 7, 14 and 28 days age of curing. The results showed that water requirement for the required workability of the sandcrete increased with increase in RHA content whereas compressive strength decreased with increase in RHA content. However, the comparison of compressive strengths of RHA sandcrete blocks with the strength of commercial concrete blocks available in the market and used as masonry units in Pakistan showed that sandcrete blocks having sand to binder ratio of 1:8 and using up to 40% of RHA as replacement of cement gave larger compressive strength than that of commercial concrete blocks and only marginally lower strength for 50% replacement.

Opis:: Contamination of soil and water with petroleum during its extraction, collection, transportation, storage and preparation occurs frequently, and purification of oil spills is one of the pressing environmental problems of oil producing organizations. There are a large number of methods for utilization oil spills. The sorption method in combination with bioremediation is capable of effectively purification of petroleum contaminated soils. The paper shows the possibility of using a carbonized mixture of shungite from the Koksu deposit (Kazakhstan) with rice husk as a sorbent and carrier of microorganism strains. The physicochemical properties and elemental composition, as well as the microstructure of carbonized samples were established. The maximum sorption capacity of carbonized sorbents when purifying the soil samples from oil from the Karazhanbas field was 1.86 g/g after 60 days. The carbonized samples with microorganism strains immobilized on them showed a degree of oil destruction reaching 90%.

Opis:: Abstract A novel floating controlled release drug delivery system of Sitagliptin phosphate was formulated in an effort to increase the gastric retention time of the dosage form and thereby increased drug bioavailability. The tablets were prepared by wet granulation method using Psyllium Husk and tragacanth gum as a release retarding polymers and sodium bicarbonate as a gas generating agent. All the designed nine batches of floating tablets were evaluated for physical characteristics viz. weight variation, thickness, content uniformity, hardness, floating capacity, swelling studies. All formulations had floating lag time of less than 1 min and constantly floated for 12 h except F1, F4 and F7 (that dissolved completely in 8 h or less than 8 h). In vitro drug release studies were carried out for 8 h and release mechanism was further evaluated by linear regression analysis, F9 composed of 30% Psyllium Husk, 10% tragacanth gum and 18% sodium bicarbonate sustained the drug release for longer period. The formulations followed first order kinetics, Higuchi drug release kinetics with diffusion as the dominant mechanism of drug release and the release exponent ranged (0.452-0.635) indicating that the drug release from all formulations was by non-Fickian diffusion mechanism. The prepared floating tablets of STP (F9) might be a promising drug delivery system with sustained release action and improved bioavailability.

Opis:: Iron is one of the groundwater contaminants that negatively impact health and the environment. This study is attempted at introducing low cost natural adsorbent for that adsorbs iron from synthetically prepared iron water. Sawdust and barley husks were used as a filter media, either alone or at different mixing ratio of sawdust/barley husks (1:1, 0.5:1, 1:0.5), to study the effect of adsorbent dose on the removal efficiency. Synthetic water of iron was used at different initial concentrations (10, 25, 40, 65, and 80) mg/L to study the effect of initial iron concentration on the removal efficiency. The filtration process was conducted at a surface loading rate of 3 m3/m2.hr. The results showed higher removal efficiency with the increase of iron initial concentration. The results indicated that removal of iron ranged (90–99.34%) for all types of filter media. The best removal was found to be 99.34% at a mixing ratio of 0.5:1 (sawdust/barley husks) at 80 mg/L initial concentration. As a conclusion, Removal of iron was very successfully observed with absorbent materials sawdust and barley husk, which makes the treatment of iron even possible in rural areas and when high concentration of iron is present.

Opis:: The experiment was conducted in the years 2007–2008. Its purpose was to compare the germination, further growth and the quality of seedlings of annual plants grown on a traditional medium (peat) and on a medium with the addition of cocoa husks. The test plants were: Tagetes erecta, ‘Klaun’ cv., Tagetes patula nana, ‘Bolero’ cv., Impatiens walleriana, ‘Candy White’ and ‘Candy Red’ cvs. Seeds of all the taxons were sown onto two media: 1. deacidified high peat with the addition of Azofoska fertilizer in the dose of 2 g dm–3 (control medium); 2. peat + cocoa husks (1:1 v/v). Cocoa husk constituted a waste product from a confectionery plant, prior to use it had been composted for a period of approx. 12 months. Chemical analysis of the cocoa husks has shown that this component is rich in nutrients. After the 12-month period of composting the structure of the husks changed, the pH value of the husks dropped, their electrical conductivity (EC) lowered, and the amount of plant-available nitrogen increased. It was found that the 1:1 v/v cocoa husk medium, used for sowing shortened the time of plant emergence and also shortened the production period of marigold and impatiens seedlings by 6 to 14 days. Cocoa husks favourably influenced the development of the root system and accelerated the blossoming time of the tested cultivars.
Celem doświadczenia przeprowadzonego w latach 2007-2008 było porównanie kiełkowania i dalszego wzrostu oraz jakości rozsady roślin jednorocznych uprawianych w podłożu tradycyjnym (torf) oraz w podłożu z dodatkiem łuski kakaowej. Roślinami testowymi były: Tagetes erecta odm. 'Klaun', Tagetes patula nana odm. 'Bolero', Impatiens walleriana odm. 'Candy White' i 'Candy Red'. Nasiona wszystkich taksonów wysiano do dwóch podłoży: 1. odkwaszony torf wysoki z dodatkiem nawozu Azofoska w dawce 2 g dm -3 (podłoże kontrolne); 2. torf + łuska kakaowa (1:1 v/v). Łuska kakaowa stanowiła odpad pochodzący z zakładu cukierniczego, przed użyciem do doświadczeń kompostowano ją przez okres około 12 miesięcy. Analiza chemiczna łuski kakaowej wykazała, że komponent ten jest zasobny w składniki pokarmowe. Po rocznym okresie kompostowania zmieniła się struktura łuski, obniżyło się pH łuski, obniżyła się także konduktywność (przewodność właściwa EC), wzrosła natomiast ilość dostępnego dla roślin azotu. Stwierdzono, że podłoże z dodatkiem łuski kakaowej (1:1 v/v), zastosowane do wysiewu przyspieszyło wschody, a także skróciło okres produkcji rozsady aksamitki i niecierpka od 6 do 14 dni. Łuska kakaowa korzystnie wpłynęła na rozbudowę systemu korzeniowego i przyspieszyła kwitnienie roślin badanych odmian.

Opis:: Arsenic is one of the most harmful pollutants in groundwater. In this paper, the Nepali bio sand filter (BSF) was modified with different bio-adsorbents, and proved to be an efficient method for arsenic removal from groundwater. Three different bio-adsorbents were used to modify the Nepali BSF. Iron nails and biochar BSF, ~96% and ~93% arsenic removal was achieved, within the range of WHO guidelines. In iron nails, BSF and biochar BSF ~15 dm3∙h–1 arsenic content water was treated. In the other two BSFs, rice-husk and banana peel were used, the arsenic removal efficiency was ~83% of both BSFs. Furthermore, the efficiency of rice-husk and banana peel BSFs can be increased by increasing the surface area of the adsorbent or by reducing the flow rate.

Opis:: The characteristics of $MgH_2$ as a hydrogen storage material in this study were observed by varying the composition of the catalyst. The added catalyst was a dual catalyst, namely nickel and natural silica extracted from rice husk ash with a composition of $MgH_2$ + 10 wt% $SiO_2$ + 10 wt% Ni (Sample A), then $MgH_2$ + 5 wt% $SiO_2$ + 10 wt% Ni (Sample B) , and $MgH_2$ + 10 wt% $SiO_2$ + 5 wt% Ni (sample C). The samples were prepared using the high energy ball milling (HEBM). The results showed that the natural silica extracted from rice husk ash (hereafter called “RHA“) can be used as a catalyst in $MgH_2$. Then, simultaneous use of nickel with silica as dual catalyst has shown the improvement in the hydrogen storage characteristics such as temperature and desorption time. The results of this study also indicate that the composition of the catalyst affects the particle size, although the time and milling treatment are the same. Furthermore, the particle size affects the characteristics of $MgH_2$ as a hydrogen storage material. Apart from particle size, there are other parameters that influence the characteristics of $MgH_2$, which appear during the sample preparation process such as impurity and agglomeration phases, all of which are closely related to the composition and type of catalyst used and the milling treatment applied to the sample. The 10 hours milling time used in this study has succeeded in reducing the sample to nano size. The Mg-based materials which have a nanostructure will have a larger contact area for the hydrogen reaction. The diffusion distance during the hydrogen absorption reaction also becomes smaller so as to improve the kinetic and thermodynamic characteristics of $MgH_2$.

Opis:: In this work, chemically treated microcrystalline cellulose (MCC-C) was extracted from coconut husk fiber. In order to extract hemicellulose, the sieved coconut husk fiber was treated with sodium hydroxide (NaOH) for dewaxing and acidified using sodium chlorite (NaClO2 ) to extract the residual lignin (bleaching process). The obtained lignin-free cellulose was then treated with potassium hydroxide (KOH). The characterizations used to equate the MCC-C with commercial grade microcrystalline cellulose (MCC) are solubility test, X-ray diffractogram (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The XRD showed that the crystallinity of MCC and MCC-C increased significantly by 80.15% and 71.8% by chemical treatments. TGA found that the active removal of lignin-hemicelluloses and the thermal stability of the material were about 350–500°C and 300–500°C. The morphology of the fiber confirmed that there is an irregular cross-section, non-uniform surface, a large amount of short microfibrils and some impurities on the surface of the coconut husk fiber. The findings showed that microcrystalline cellulose has been successfully extracted from coconut husk fiber and that it can be used further.
Celulozę mikrokrystaliczną (MCC-C) wyekstrahowaną z włókien łupiny orzecha kokosowego poddano obróbce chemicznej. Na przesiane włókna łupin orzecha kokosowego działano roztworem wodorotlenku sodu (NaOH) w celu usunięcia wosku, następnie zakwaszono je roztworem chlorynu(III) sodu (NaClO2), w celu ekstrakcji resztkowej ligniny (proces bielenia). Na otrzymaną, pozbawioną ligniny celulozę działano wodorotlenkiem potasu (KOH). Porównano uzyskaną MCC-C z handlową celulozą mikrokrystaliczną (MCC) na podstawie przeprowadzonego testu rozpuszczalności, badań metodami dyfrakcji rentgenowskiej (XRD), analizy termograwimetrycznej (TGA) i skaningowej mikroskopii elektronowej (SEM). Wyniki badań XRD wykazały, że po obróbce chemicznej krystaliczność zarówno MCC, jak i MCC-C zwiększyła się istotnie o, odpowiednio, 80,15% i 71,8%. Wyniki badań TGA wykazały, że aktywne usunięcie lignin-hemiceluloz powoduje zwiększenie stabilności termicznej celulozy mikrokrystalicznej i przesunięcie temperatury rozkładu do zakresu, odpowiednio, 350–500°C i 300–500°C. Analiza morfologii włókien potwierdziła ich nieregularny przekrój poprzeczny, niejednorodną powierzchnię, dużą liczbę krótkich mikrofibryli oraz zanieczyszczenia na powierzchni. Stwierdzono, że celuloza mikrokrystaliczna wyekstrahowana z włókien łupiny orzecha kokosowego nadaje się do wykorzystania.

Opis:: This study compares the mechanical properties of recycled high-density polyethylene (r-HDPE)/rice husk (RH) composites from a twin-screw extruder and a heated two-roll mill, and the effect of different filler loadings using different melt blending processes on the mechanical properties of r-HDPE/RH composites. Polyethylene-graft-maleic anhydride (MAPE) acts as the coupling agent to enhance interfacial bonding between the fibre and the polymer matrix. The filler loading used was in the range of 10-40 wt. %. In this work, r-HDPE/RH blends were prepared using a twin-screw extruder and a heated two-roll mill. The ratio of 70/30 twin-screw extruder compounded composites significantly showed higher tensile based on improved to about 45.5% at 11 MPa compared to those compounded in the heated two-roll mill. The same ratio showed an increment almost up to 9% of elongation at break. It has also been verified that the higher filler loading used reduced the tensile strength and elongation at break, while the Young’s modulus increased. The result was evidenced by the increase in water absorption and longer burning time as the filler loading increased.

Opis:: This study demonstrates the comparison in the method of fabrication and thus evaluates the potential of psyllium husk powder and gelatin-based composite microporous scaffolds for tissue engineering applications. The scaffold is being prepared in three different ratios of 50:50, 75:25 and 100 (w/w of psyllium husk powder and gelatin, respectively) by employing a suitable cross-linking agent, EDC-NHS, followed drying. We have demonstrated the use and outcomes of two different methods of scaffold drying, i.e., vacuum desiccation along with liquid nitrogen dip and lyophilization. It was concluded from the SEM micrographs that the scaffolds dried under vacuum accompanied with liquid nitrogen exposure exhibited less porous architecture when compared to those prepared using a lyophilizer, that resulted in pores in the range of 60-110 μm. Scaffolds fabricated using the former technique lost porosity and sponge-like characteristics of a scaffold. In spite of the above fact, water retaining capacity and stability in the cell culture of such scaffolds is significant, nearly 40-50% of its initial dry weight. Cell culture experiments support the potential of the scaffolds prepared from different methods of fabrication for its cytocompatibility and suitability for cell growth and proliferation for a substantial duration. Erosion in the porous design of the scaffolds was observed after 14 days via SEM micrographs. It was inferred that freeze-drying is a better technique than vacuum desiccation for scaffold preparation. The present investigation has been conducted keeping in mind the importance of drying a scaffold. Scaffold drying is a necessary step to increase its shelf-life, makes it easy to transport and much importantly, controlling the pore size of the scaffold.
