In recent time, green synthesis of Metal Nanoparticles (MNPs) is the latest developing technology and received exceptional interest because it is simple, eco-friendly, pollutant-free, nontoxic, and a low-cost approach. Green route of biogenic synthesis of metal nanoparticles via microbes (bacteria, fungi, virus, yeast, algae etc.) has the potential to deliver clean manufacturing technology. Fungi are in the great use for the s Read More

Deformation twins and phase interface are important planar defects and microstructures that greatly influence the overall performance of a material system. In multi-layer thin-film heterostructures, their effect is more manifest due to the small dimension of thin films and their influence on the growth of multi-layer structures. This article reviews the recent progress in microstructure and defects observed in thin film hete Read More

Aim: The purpose of this study was to test the phytotoxicity effect of ZnONPs on Vigna mungo L. seedling growth and antioxidant activity. Methods: Vigna mungo L. Seeds were treated with to a wide range of ZnO NPs ranging 5 to25mg/100ml for 8hours. Vigna mungo seeds that were soaked in ZnO NPs solution were sown in pots (20 cm × 40 cm) filled with red soil and a layer of coco peat. The effect of ZnO NPs on morphologic Read More

Background: Iron oxide (γ-Fe2O3) nanoparticles have been prepared by a simplified coprecipitation method. Methods: X-ray diffraction peaks of the prepared nanoparticles match well with the characteristic peaks of crystalline g-Fe2O3 as per JCPDS data (JCPDS Card No. 39-1346) and absorption peak at 369 nm along with band gap 2.10 eV suggesting the formation of (γ-Fe2O3) nanoparticles. Results: The γ-Fe2O3 nanoparticles a Read More

Background: This research indicated that such abstract are more informative and more readable, in field of preparation of nanocomposite materials. Aim: The purpose of this work represented by decoration of Carbon Nanotubes (CNTs) with nanoparticles using co-precipitation method and exhibit different physical properties from those of CNTs alone and its appropriate for this particular journal. Methods: Preparation M Read More

Background: Electrospinning is a novel cost effective technique for generating nanofibers from a broad range of materials likely to be used as a coating film. Methods: In this project, pectin and chitosan solutions containing PVA were prepared and electrospun with separate syringes for the first time. The antimicrobial and physical properties of the novel chitosan/PVApectin/ PVA nanofibrous film were evaluated using some a Read More

Introduction: This paper proposes an approach for parameter estimation of the Classical and Generalized Morse Potential functions. A new potential which is a modification of the Generalized Morse Potential was proposed as parameter estimates yielded complex conjugate roots using gold atom for simulation. Methods: Existing methods of parameter estimation requires the provision of initial guess values of which convergence to Read More

Background: Rare earth materials are known for its salient electrical insulation properties with high values of electrical resistivity. It is expected that the substitution of rare earth ions into spinel ferrites could significantly alter its magnetic properties. In this work, the effect of the addition of Samarium ions on the structural, morphological and magnetic properties of Ni0.5Zn0.5SmxFe2-xO4 (x=0.00, 0.02, 0.04, 0.06, 0.08, 0.10 Read More

Background: This work describes the implementation of In0.53Ga0.47As/InP Surrounding Metal Gate Oxide Semiconductor Heterostructure Field Effect Transistor (SG MOSHFET) with gate underlap on both source and drain end to improve the DC and RF performance. Methods: A comprehensive and methodological investigation of DC and RF performance of III-V semiconductor are made for different underlap leng Read More

Background: Magnetic cell immobilization has been introduced as a novel, facile and highly efficient approach for cell separation. A stable attachment between bacterial cell wall with superparamagnetic iron oxide nanoparticles (SPIONs) would enable the microorganisms to be affected by an outer magnetic field. At high concentrations, SPIONs produce reactive oxygen species in cytoplasm, which induce apoptosis or ne Read More

Background: CdSe QDs, synthesized using a green micro-emulsion method, have been evaluated for their potential in inducing HL-60 differentiation by employing various biochemical assays and as cellular imaging agents. Methods: CdSe QDs have been found to effectively induce differentiation with lower rate of cell apoptosis as compared with the positive control (DMSO). Results: Our results exhibit effective induction of HL-60 di Read More
