Opis:
In this study, three experiments using the fixed anode technique and approached anode technique were carried out. The first experiment (EK-1) used distilled water as leaching solution (purging solution) at the anode and cathode chamber under voltage gradient was equal to 1.5 V/cm. In the second and third experiments, a solution enhanced with 1M acetic acid (AA) was used as catholic solution. The results indicate that residual concentration of Zn+2 decreases, beginning with an initial value of 850 mg/kg in all portions of soil sample EK-1, EK-2, in addition to EK-3. It seems that the residual concentration of EK-3 (approached anode technique) was lower than that of EK-1 and EK-2 in identical portions.

Opis:
The article describes the modern problems of formation and purification of marine oil-containing waters. The efficiency of using electrocoagulation to remove oil from water-oil emulsions of different mineralization using aluminum and iron anodes was studied. Treatment of water-oil solutions with an oil content of 100 mg/dm3 by electrocoagulation in a single-chamber electrolyzer provides 98–99% oil removal using these electrodes at an anode current density of 0.57–2.11 A/dm2 for highly mineralized waters and 0.34 A/dm2 for freshwater treatment during the first 15 minutes provides a reduction in oil concentration from 100 mg/dm3 to values at the level of 1.55–2.93 mg/dm3. When the water treatment time is extended to 45 minutes, greater efficiency in highly mineralized waters is provided by the aluminum anode.

Opis:
Bulk heterojunction solar cells were investigated using poly(3-hexylthiophene) (P₃HT):[6,6]-phenyl-C₆₁ butyric acid methyl ester (PCBM) with a nickel oxide (NiO) anode buffer layer between the photoactive layer and an indium tin oxide (ITO) anode layer. The NiO anode buffer layer was deposited using radio frequency magnetron sputtering on an ITO electrode layer for effective hole transport and electron blocking. The NiO film is a p-type semiconductor with resistivity of 0.35 Ω cm. The power conversion efficiency was improved substantially by the NiO anode buffer layer compared to a solar cell with an anode buffer layer made from poly(3,4-ethylenedioxythiophene) (PEDOT):poly(styrene sulfonate) (PSS). The solar cell with a 10 nm thick NiO anode buffer layer had a power conversion efficiency of 4.71%. These results are explained by the improved charge transport across the interface between the active layer and ITO electrode.

Opis:
Adherent anode slimes can cause anode passivation in copper electrorefining and lower the efficiency of copper electrorefining. Declining concentrate grades cause larger impurity levels in anodes, thus creating larger quantities of slimes in the refining process. In order to investigate the characterization methods for adherent anode slimes in copper electrorefining, experiments were conducted for the Boliden Harjavalta Pori refinery material. Methods such as particle size determination, chemical (ICP) analysis, settling rate determination, XRD, SEM-SE, SEM-BSE and SEM-EDS were applied. In addition, adherent anode slime samples were compared to optical micrograph and SEM-BSE images of respective anode copper samples. It was shown that SEM-EDS and SEM-BSE provided precise information about phases formed during electrorefining. The settling rate and particle size had a correlation only with a copper content of anode slime. The main phases in the anode slime were copper and lead sulphates as well as copper-silver selenides. NiO was shown to be the major Ni-bearing phase in the adherent slime. Nickel, tellurium and lead had the strongest, whereas arsenic, selenium and antimony had the weakest tendency to report to the anode slime.

Opis:
Copper reduction represents one of the steps in the process of fire refining of blister copper. Process of copper reduction with natural gas as performed in the anode furnace was modeled. Numerical analysis was conducted using the IPSA (Inter- Phase-Slip Algorithm) module of PHOENICS package and standard turbulent model k - ε. The model takes into account the liquid phase - slag and phase of natural gas which is supplied through the tuyere from the bottom of the charge. Calculations were made for two different diameters of tuyeres for supply of reducer. Based on the calculations and analysis, it was found out that the gas flow which causes strong movement in the bath guarantees homogeneous composition of the liquid copper in each process stage. Application of a tuyere with a larger diameter results in a greater intensity of the reduction process and better use of the reducer.

Opis:
Lithium-ion batteries are not situable for electric vehicles with high millage, military power supplies and fixed power networks. Therefore, the Li-S batteries have been intensively investigated, due to the high capacity, low cost, widespread source, and nontoxicity. The development of Li-S batteries causes increasing need to find the methods for their recycling. Some of them are discussed in the paper. The recycling of Li-S cell relates to its anode, cathode, electrolyte, binder and separator. The Li-S battery should be fully charged before recycling. There are potential methods for recycling of lithium from anodes, especially by re-melting. It is also possible to recycle some materials from the cathodes, especially sulfur by re-melting and graphite by dry crushing, Eco-bat Technologies method or the method investigated by Xiang et al. There is no effective recycling methods for electrolytes, binders and separators. It is necessary to carry out further studies on them.

Opis:
Superior catalyst utilization of direct methanol fuel cells (DMFCs) may be obtained by localized catalyst loading on reaction sites. The objective of this work is to improve the catalyst utilization by multi-layer structure and reduction of loading catalyst. Multi-layer anode consisted of sputter-deposited Pt-Ru catalyst layer and the support layer of Nafion-carbon-Isopropanol ink (NCI). Single layer anode consisted of sputter-deposited Pt-Ru catalyst layer and the layer of carbon-glycerin ink (CG). Multi-layer (1~4 layers) and single-layer (0.04, 0.10 and 0.24 mg cm-2) were evaluated by using electrochemical measurement and SEM images. Three-layer anode provided 50.9 W g-1, 3.4 times as mass activity of conventional paste method anode. Methanol residues stripping voltammetry revealed that electrochemical surface area (ECSA) was increased with the number of layers. Additionally, single-layer anode (0.04 mg cm-2) provided over 150 W g-1. These results suggested that reduction of loading catalyst per unit layer and multilayer structure enhanced catalyst utilization.

This technology makes possible long-term storage of crustaceous waste at unnormalized positive temperatures with simultaneous shell deproteinization. Due to the mild exposure conditions the electrochemical methods allow to preserve the high quality of valuable components (chitin, proteins, lipids, carotinoids and others) and to carry out comprehensive processing. The preservation of expired crustaceous waste with increased original bacterial content was found possible.

Opis:
The recovery of spent carbon anode (SCA) materials plays important roles in environment protection and resources recycling, while this cannot be efficiently achieved without liberation. In this study, grinding characteristics of spent carbon anode from aluminum electrolysis in both ball mill and rod mill were analyzed, and compared based on the utilization of the selective Fuerstenau upgrading curves. In addition, the different grinding mechanisms of ball and rod milling were evaluated by analyzing the shape factor and surface roughness of the ground samples. Results of mineralogical characterizations indicated that carbon particles (d50 = 46.86 μm) presented in the SCA were closely associated with cryolite particles. At 5 min grinding time, the maximum selective comminution factor (β) values of ball milling and rod milling were 2.00 and 1.63, respectively, indicating a higher degree of selective comminution of SCA was achieved from ball milling. Comparisons of the valuable component content (cv, cum) of -125 μm ground particles and the shape characterizations of 74–125 μm ground particles generated from ball and rod milling manifest that a direct relationship exists between the degree of selective comminution and the grinding mechanism.

This paper has been written based on the author’s doctoral dissertation “Structural and transportation properties of strontium and titanate composites with ion conductive oxides”, prepared under the supervision of Prof. Dr. Hab. Eng. Bogusław Kusz at the Department of Solid State Physics of Gdańsk University of Technology. It reports the idea of the thesis and conclusions from the study. Niobium doped strontium titanate (Sr(Ti,Nb)O3) composites with selected ion conductive oxides (yttrium oxide-stabilized zirconium oxide YSZ and cerium oxide CeO2) were developed for the dissertation and their properties examined.. It was shown that Sr(Ti,Nb)O3-YSZ composite as the anode in an oxide fuel cell leads to its improved performance compared to a cell with a singlephase Sr(Ti,Nb)O3 anode. Microscopic observation confirmed that Sr(Ti,Nb)O3-YSZ composite as the functional layer between a Sr(Ti,Nb)O3 anode and YSZ electrolyte mitigates the problem of the composite anode’s delamination from the electrolyte surface. It was also shown that an appropriate modification of the Sr(Ti,Nb)O3-YSZ composite anode surface structure by infusing the process of hydrogen’s electrochemical oxidation with a catalyst (e.g. with nickel) can lead to further improvement of the fuel cell performance.
Artykuł napisano na podstawie rozprawy doktorskiej autorki pt. „Właściwości strukturalne i transportowe kompozytów tytanianu strontu z tlenkami przewodzącymi jonowo”, przygotowaną pod nadzorem prof. dr. hab. inż. Bogusława Kusza w Katedrze Fizyki Ciała Stałego Politechniki Gdańskiej. Prezentuje on ideę pracy doktorskiej oraz wnioski wynikające z przeprowadzonych badań. W pracy doktorskiej wytworzono i zbadano właściwości kompozytów tytanianu strontu domieszkowanego niobem (Sr(Ti,Nb)O3) z wybranymi tlenkami przewodzącymi jonowo (tlenek cyrkonu stabilizowany tlenkiem itru – YSZ, tlenek ceru – CeO2). Wykazano, że zastosowanie kompozytu Sr(Ti,Nb)O3-YSZ jako anody prowadzi do poprawy parametrów pracy tlenkowego ogniwa paliwowego w stosunku do ogniwa z anodą 1-fazową Sr(Ti,Nb)O3. Obserwacje mikroskopowe potwierdziły, że zastosowanie kompozytu Sr(Ti,Nb)O3-YSZ jako warstwy funkcjonalnej między anodą Sr(Ti,Nb)O3 i elektrolitem YSZ ogranicza problem delaminacji anody kompozytowej z powierzchni elektrolitu. Wykazano również, że odpowiednia modyfikacja struktury powierzchniowej anody kompozytowej Sr(Ti,Nb)O3-YSZ poprzez nasączanie katalizatorami procesu elektrochemicznego utleniania wodoru (np. niklem) może prowadzić do dalszej poprawy parametrów pracy ogniwa paliwowego.

Opis:
There is a real need to use various efficient energy supply systems that are not aggressive towards the global environment. Hydrogen has been seen in different research papers presented in the literature as an essential fuel to generate energy in various energy storage systems. As it is well-known, it is possible to generate renewable electricity using electrolysis. The hydrogen produced can be sold as fuel for various systems, most notably its use in solid oxide fuel cells and a host of modern applications today. Current low-temperature fuel cells are ideal for hydrogen operation, but are not suitable for hydrogen mixtures. In this article, a mathematical analysis was carried out to generate electrical energy in a fuel cell, fed with synthesis gas from the residual biomass gasification process; the primary interest was the generation of electrical energy, solid oxide fuel cell (SOFC), which operate at the temperature of the gas at the outlet of the gasifier were analyzed. The practical efficiency obtained and the theoretical results of the SOFC operation were shown.

This work is concerned with a study on the operating characteristics of a self-axial extraction-type glow-discharge ion source. This compact ion source, with conical anode of various divergence angle Θ, can work under different operating conditions. An output ion beam currents I_{b} were measured at a distance d_{cc} = 5 cm from the plane cathode, and were found to be dependent upon the gas pressure p, angle Θ and the discharge current I_{d}. High ion beam currents of 85 μA and 410 μA were obtained at the optimum angle Θ=30° for discharges: [N₂ gas, p = 2.9×10¯² mbar, I_{d} = 2 mA] and [H₂ gas, p = 7.7×10¯² mbar, I_{d} = 2 mA], respectively.

Opis:
Due to the need for comprehensive management of energy resources, the storage of energy becomes an increasingly important issue. From the analysis of the advantages and drawbacks of all methods of energy storage, reversible electrochemical cells seem to be the most effective. Among them, rechargeable lithium batteries are characterized by high energy density (Fig. 1), high voltage and good cyclic stability [7]. Thus, they have been a dominant technology of energy storage systems for over a decade. It is expected that market demand for Li-Ion cells in the coming years will grow at a rapid rate, as a result of their widespread use inter alia in portable electronic devices such as mobile phones, smartphones, tablet PCs and laptops (Fig. 2) [9]. This article presents the characteristics of lithium batteries. The most commonly used cathode material in Li-Ion battery is layered cobalt oxide (130 mAh/g). However, it is expensive and toxic material, thus manganese-based compounds (LiMnO2, LiMn2O4), polyanionic olivine structured materials (LiFePO4) and silicates Li2MSiO4 (M = Mn, Co, Fe) gain an increasing interest. Due to the presence of two lithium ions in the structure of silicates, these materials have a high theoretical capacity, reaching about 300 mAh/g (Tab. 2) [1, 7–9, 11, 12]. Commercially used anode material is graphite (372 mAh/g). Nevertheless, scientists are still looking for new anode materials with a higher gravimetric capacity. Researches are primarily focused on modifications of the graphite or the use of lithium alloys with other elements (Sn, Al, Si) (Tab. 3) [1, 9, 12, 14, 15]. In the Lithium-Ion cells only non-aqueous solutions are used in the character of electrolytes. As a best material, the inorganic electrolyte lithium salts (such as LiBr, LiAsF6, LiPF6, LiBF4, etc.) soluble in organic solvents are used [1, 2, 7, 8]. However, the study on alternative solutions (polymer electrolytes) is very important. Continuous technological progress makes the research on improving the reversible electrochemical cells necessary to fulfill the expectations of users in order to improve the quality of their lives.

Opis:
The paper discusses plasma methods for surface modification using the non-self-sustained glow discharge with a hollow anode. This discharge is characterised by low voltage and high values of electron and ion currents. It can be easily excited in vacuum-arc installations that are widely used for coatings deposition. It is shown that such type of discharge may be effectively used for ion pumping, film deposition, ion etching, diffusion saturation of metallic materials, fusion and brazing of metals, and for combined application of above mentioned technologies in a single vacuum cycle.

Opis:
To investigate the dynamics of a planar plasma diode system (PDS), a model based on the current density equilibrium at the interface was developed. The current densities and plasma boundary variations with the potential fields were obtained by simulating a single square pulse. The variation of an observed overshoot current density with the applied voltage is presented. Planar plasma diode system was also simulated for periodic, sine, square, triangular and saw tooth voltage patterns by varying the amplitude and frequencies. A method to find the lower bound of the electron density of plasma for a specified PDS is presented. Particle-In-Cell simulation technique was used to investigate the plasma particles and electric field distributions over the anode cathode gap for different intensities of external electric fields. The system became stable after few time steps and this time depends upon the intensity and polarization of the external field.

Opis:
Sodium-ion batteries (SiBs) have attracted substantial interest as an alternative to lithium-ion batteries because of the low cost. There have been many studies on the development of new anode materials that could react with sodium by conversion mechanism. SnO2 is a promising candidate due to its low cost and high theoretical capacity. However, SnO2 has the same problem as other anodes during the conversion reaction, i.e., the volume of the anode repeatedly expands and contracts by cycling. Herein, anode is composed of carbon nanofiber embedded with SnO2 nanopowder. The resultant electrode showed improvement of cyclability. The optimized SnO2 electrode showed high capacity of 1275 mAh g-1 at a current density of 50 mA g-1. The high conductivity of the optimized electrode resulted in superior electrochemical performance.

Opis:
Yttria-stabilized zirconia (YSZ) is the best known ceramic-oxide material employed as a component of either solid electrolyte or anode cermet material for intermediate solid oxide fuel cell (IT - SOFC). The properties of traditionally produced (by mechanical mixing of oxides) Al2O3/3YSZ composite with the same composition materials obtained by citrate and impregnation methods and with properties of pure tetragonal zirconia (3YSZ) were compared. The materials were characterised by X-ray diffraction, SEM observations with EDX analysis, density and impedance spectroscopy measurements. The results shown that Al2O3/3YSZ composites reveals higher conductivity than pure 3YSZ and that addition of alumina (regardless of methods) improve electric properties of resulting materials. Taking into account application of this materials as anode in IT-SOFC the determined values of energy activation of conductivity and microstructural properties of composites show that materials obtained by citric method are the most promising.
Tlenek cyrkonu (IV) stabilizowany itrem (YSZ) jest jednym z najlepiej poznanych tlenkowych materiałów ceramicznych stosowanych jako składnik zarówno elektrolitów stałych jaki i materiałów anodowych dla stałotlenkowych ogniw paliwowych (SOFC). W pracy zostały porównane właściwości tradycyjnie produkowanego (poprzez mechaniczne mieszanie tlenków) kompozytu Al2O3/3YSZ z właściwościami analogicznych materiałów wytworzonych metodą cytrynianową oraz impregnacji oraz z właściwościami czystego 3YSZ. Otrzymane materiały badano metodami dyfrakcji rentgenowskiej, skaningowej mikroskopii elektronowej (SEM) z jednoczesną analizą EDX, spektroskopii impedancyjnej oraz wykonano analizę gęstości próbek. Wyniki badań pokazały iż niezależnie od sposobu wprowadzenia Al2O3 do układu, kompozyty Al2O3/3YSZ wykazują wyższe przewodnictwo niż czysty 3YSZ. Ponadto stwierdzono, biorąc pod uwagę możliwość zastosowania badanych materiałów jako materiał anodowy w IT-SOFC, iż najbardziej obiecujące właściwości mikrostrukturalne oraz elektryczne posiadają materiały kompozytowe otrzymane metodą cytrynianową.

Opis:
Mechanisms of the charge transfer, the charge trapping, and the generation of positive charge during the high-field electron injection into buried oxide of silicon-on-insulator structures fabricated by different technologies are analyzed based on the data obtained from current-voltage, injection current-time, and capacitance-voltage characteristics together with SIMS data. Electron injection both from the Si film and the Si substrate is considered. The possibility of using the trap-assisted electron tunneling mechanisms to explain the high-field charge transfer through the buried oxides of UNIBOND and SIMOX SOI materials is considered. It is shown that considerable positive charge is accumulated near the buried oxide/substrate interface independently from the direction of the injection (from the film or from the silicon substrate) for UNIBOND and SIMOX SOI structures. Thermal stability of the charge trapped in the buried oxides is studied at temperatures ranging from 20 to 400° C. The theory is compared with the experimental data to find out the mechanisms of the generation of positive charge in UNIBOND and SIMOX buried oxides.

Opis:
The influences of various operating conditions including cathode inlet air flow rate, electrolyte temperature and fuel particles size on the performance of the direct carbon fuel cell DCFC were presented and discussed in this paper. The experimental results indicated that the cell performance was enhanced with increases of the cathode inlet gas flow rate and cell temperature. Binary alkali hydroxide mixture (NaOH-LiOH, 90-10 mol%) was used as electrolyte and the biochar of apple tree origin carbonized at 873 K was used as fuel. Low melting temperature of the electrolyte and its good ionic conductivity enabled to operate the DCFC at medium temperatures of 723-773 K. The highest current density (601 A m-2) was obtained for temperature 773 K and air flow rate 8.3 x 106 m3s-1. It was shown that too low or too high air flow rates negatively affect the cell performance. The results also indicated that the operation of the DCFC could be improved by proper selection of the fuel particle size.
