Opis:
A series of (4-(7-chloroquinolin-4-yl)piperazin-1-yl)(substitutedphenyl)methanones were prepared via multistep synthesis which involved acrylation without base, cyclisation, hydrolysis, decarboxylation, electrophilic chlorination reactions and subsequent chloro-amine coupling with various substituted benzoyl chloride derivatives. The structure of the synthesized compounds was established by using elemental analysis, FT-IR, 1H NMR, 13C NMR and Mass spectroscopy. All the novel compounds have been tested on thin layer chromatographic plate for purity and evaluated for their antimicrobial activity against gram positive and gram negative bacteria which demonstrated moderate to good antimicrobial activity.

Opis:
Nanotechnology is the most emerging branch of science and technology leading to the development of devices starting from electronics to biomedical devices. It is thus desired that the students should have basic idea of this new emerging technology during their school education. Experimental demonstration of simple experiments of synthesizing nanomaterials and demonstration of its properties are very much important in motivating the students to learn this new technology. Wet chemical synthesis method is a simple and cost-effective method that can be adopted in the chemistry laboratory of higher secondary level school education in India. This hands-on experience will encourage the students to enter more into this nanotechnology.

Opis:
The synthesis of a novel xanthene derivatives bearing dimedone as an excellent precursor has been achieved by applying one pot three component Hantzsch type condensation. The newly synthesized compounds were characterized by spectral and elemental analyses. All synthesized compounds undergo docking studies and biological screening for antimicrobial activity against Gram-positive bacteria, Gram-negative bacteria and fungal species. Among all the tested compounds, it was found that compound 3c, 3d, 3g and 3h revealed better activities against the Gram-positive rather than the Gram-negative bacteria whereas results of docking studies revealed that compounds 3b, 3g and 3i showed best binding affinity towards ATP binding pocket of Human PIM1 kinase receptor through steric favorable and H-bond interactions.

The synthesized Ni-alloy was prepared via conventional casting technique under vacuum and highly superheated treatment route. The casting parameters such as solidification cooling rate (SCR) was monitoring by both of AFM and SEM .Micro-structural investigations within different spots in the same sample indicated that γ matrix is the domain phase besides minor phases as MC carbides, σ phase and η phase which was observed to solidify in two forms as plate-like and blocky shape. The volume fraction (Vf) of σ and η phases was increased as the solidification cooling rate decreases. 3D-microstructural imaging map of the Ni-based super-alloy was constructed depending upon AFM-data evaluating that the morphology of the alloy-surface is a function of casting parameters .Furthermore raman spectra of highly superheated casted Ni-based super-alloy was performed to confirm existence of different phases recorded via SEM and EDX-elemental analysis with their corresponding different vibrational modes such as Ni-O vibrating modes in the region 360-510 cm-1 and Mo-O vibrating mode which lies at 1005 cm-1.

The selected sample of synthetic free fluoride – Na-4-mica was having the general formula (Na4Mg6M4Si4O22•nH2O) where M = Cr3+ was exposured to two different ɤ-irradiation doses 1st dose = 1.5 MR/h and 2nd dose = 3 MR/h at 25 cm distance. Structural parameters such as lattice constants, volume and phase quality were monitoring carefully by using both of XRD and SEM evaluating grain size of the mica bulk. Structural investigations proved that Cr-clay exhibits monoclinic phase accompanied with structure quality in comparison with both of Bi-and Al-clays

Opis:
The present communication reports a rapid, uncomplicated, sustainable and facile method of eco-friendly synthesis of silver nanoparticles (AgNPs). The pressing need for the development of benign, profitable and eco-friendly alternative routes has inspired researchers to explore plant extracts as safer replacements to hazardous chemicals. In the present study, a benign method of synthesis of AgNPs using Soymida febrifuga aqueous root extract has been developed. The characterization studies of synthesized AgNPs revealed spherical morphology and crystalline nature of AgNPs. The average particle size was 21.81 nm. The synthesized AgNPs were employed as mercury nanosensor for the selective and sensitive detection of toxic mercury ions in water and soil samples. The AgNPs showed a marked visual color change and change in surface plasmon resonance band on interaction with mercury ions. The greater selectivity of AgNPs towards mercury ions was observed. The limit of detection of mercury by 100 μL of colloidal AgNPs was found to be 2×10-4 M visually and 1.332×10-5 M spectrophotometrically in water samples and ×-4 M visually and 22.3×10-5 M spectrophotometrically in soil samples. The method makes use of a small quantity of AgNPs for detection of mercury in water and soil samples. The method proposed in the present study provides a rapid, selective and sensitive method for detection of mercury ions in environmental water and soil samples. The synthesized AgNPs were also used as effective microbicidal agents. The microbicidal potential of the synthesized AgNPs was checked against two gram positive and gram negative bacterial strains.

Structural and microstructural properties were monitoring by using both of XRD and SEM evaluating that indium doped - calcium vanadate ceramic has the semiconducting classical doubly perovskite phase as proved in the X-ray diffractogram, grain size of the material bulk was found to be in between 1.57- 2.23 μm which are lower than those reported in literatures .Magnetic measurements indicated that the In- doped- calcium vanadate ceramic exhibits an semiconducting behavior confirming that indium- hole dopings enhance the paramagnetic character and semi-conduction mechanism of the hexagonal perovskite phase. Furthermore 3D-AFM investigations were made to study effect of indium doping on the surface topology and grain size in the material bulk.

Opis:
In this paper, the effect of pH on nanoparticles (AgNPs) using plants extracting has been investigated. The aqueous sol of AgNPs prepared at different pH values using hydrothermal method display different Surface Plasmon Resonance (SPR) behavior and the maximum absorption values were at pH = 14. AgNPs were characterized using X-Ray diffraction, UV-Vis spectroscopy and scanning electron microscope. Face-center cubic Ag nanoparticles with crystal size about 3.86 nm have been noticed. The absorption band showed that Ag has sharp curves in the ultraviolet and at the edge of the visible region. The SEM images showed cluster shaped nanoparticles, and when increasing the pH values, the result revealed the formation of larger nanoparticles cluster with more accurate crystallite sizes. The antimicrobial and antifungal activity was performed by Agar well diffusion assay against Escherichia coli, Bacillus subtilis and Candida albicans. The diameter of the inhibition zones of Ag NPs against the bacterial strains such as, Bacillus subtilis (31 mm) and Escherichia coli (30 mm) at 200 µg/ml concentration and the diameter of the inhibition zones of Ag NPs against the fungus strains such as, Candida albicans (36 mm) at the same concentration.

Synthesis of nanoparticles using plant leaf extract is an eco-friendly, non-toxic and cost efficient approach in the field of nanotechnology. In this study, biosynthesis of stable copper nanoparticles were prepared by using Ocimum sanctum and Piper nigrum extract. These biosynthesized Cu nanoparticles were characterized with the help of X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). The crystalline size of the Copper Nanoparticles prepared from Tulsi extract is little smaller than Copper nanoparticles prepared from Pepper extract. SEM images of Copper nanoparticles showed that the cluster formation, presence of smaller and larger grains. FTIR analysis revealed that the functional groups present in the Copper nanoparticles prepared from both Tulsi and Pepper extracts. Thus, this method can be used for rapid and ecofriendly biosynthesis of stable copper nanoparticles and can be used for catalytic agent, anti-microbial, anti-fungal, anti-biotic, nanosensor, super conducting material, solar cell applications.
