Antibacterial materials based on calcium phosphates have wide range of biomedical applications in the prevention of microbial infections. The synthesis of inorganic mineral component of bone i.e. hydroxyapatite was done with the addition of silver (Ag) (5-15 wt %) as antibacterial agent. The wet precipitation synthesi…
Pyramidal surface is commonly used as an antireflection structure. The weighted reflectance averaged by the AM 1.5 G spectrum is about 14%. In the photovoltaic field, lowering the surface reflectivity is an important approach to improve the conversion efficiency. Black silicon surface with low reflectivity is benefit…
Bacterial cellulose-based carbon nanotube has been synthesized by catalytic graphitization method. Bacterial cellulose (BS) is a source of cellulose produced from fermentation of medium by Acetobacter xylinum. Since it contains unbranch polymer linked by β-1.4 glucopyronose with hydroxil groups, BS is able to use as p…
We studied the crystallographic of Barium Zirconium Titanate thin films with Aluminum doped (BZAT). These films were prepared by sol-gel process and followed by spin coating. The sintering temperature is taken at 800°C and 900°C. We found that the crystallographic system of BZAT thin films have tetragonal structure wi…
Twenty-seven scapolite samples from various localities and with compositions between Me 6–93 were obtained using electron microprobe analysis (EMPA). Their unit-cell parameters were obtained using synchrotron high-resolution powder X-ray diffraction (HRPXRD) data and Rietveld structure refinements using space group P…
Recently, huge interest has been generated in investigating the possible therapeutic use of tunable magnetic nanostructures to overcome the existing challenges to treat central nervous system damage related conditions. However, several issues (e.g., biocompatibility or remote controlled actuation for multi-modal thera…
Heterojunction (HJ) structure has the advantages of high charge collection and transport efficiency, but it also has the disadvantage of low charge collection, due to limited p-n interfaces, compared with bulkheterojunction (BHJ) structure. In order to overcome this disadvantage of HJ, we fabricated HJ solar cells wit…
The objective of the present study is to describe the results of research that has been conducted on the buckling behavior of rectangular laminated orthotropic plates that have a rectangular hole. As a result of using some geometrical holes which cause stress concentrations on laminated orthotropic plates, the analysi…
In this paper, different sintering temperature used to study the influence of temperature on the structural and thermal properties of zinc oxide (ZnO). On this research, the sample was prepared by solid-state method for zinc oxide (ZnO) at different sintering temperature which was 700°C, 800°C and 900°C. It was observ…
Polypropylene (PP)/Acrylonitrile butadiene rubber (NBRr)/rice husk powder (RHP) composites was fabricated with silane and acetic anhydride treatment agent. The in-situ formed RHP filled PP/NBRr composites were prepared by melt mixing technique using Haake internal mixer at 180 °C. The tensile properties of the both tr…
Zinc oxide (ZnO) thin films were deposited on teflon substrates by RF magnetron sputtering at different substrate temperature. The effect of substrate temperature on ZnO thin films electrical and structural properties were examined using current-voltage (I-V) measurement, and x-ray diffraction (XRD) It was found that…
Strontium titanate (SrTiO3) thin film has been deposited on Si (100) substrate using pulsed laser deposition technique. Film deposition was carried out at low temperature (150°C) by maintained the pressure at 10-4 Torr. Nanometer-thick SrTiO3 film on Si substrate was characterized using SEM, AFM, XRD, and Raman Spectr…
Cisplatin is an antineoplastic drug widely used for the treatment of several solid tumours. However, the side effects related to cisplatin-based anticancer therapy often outweigh the benefits. Therefore, the identification of new anticancer strategies able to offer a better toxicity profile while maintaining the same…
Superhydrophobic surfaces have the potential to reduce drag both in the laminar and turbulent regimes. However, the slip at the air-water interface can be adversely affected by the roughness of the structure of the surface which is needed to support the air layer. The conflicting effects of roughness and slip are inve…
The aim of the study is to identify the effect of Ca in Mg-Mn alloy on electrochemical corrosion behavior for the development of high performance sacrificial anode. Mg alloys were fabricated by casting technique under an inert atmosphere. 0.35 ~ 1.11 wt.% of Ca were added as alloying element. The finding shows that th…
Stress shielding interaction effect of two parallel edge cracks in finite body under uniaxial loading is analysed using developed finite element (FE) analysis program. In present study, the stress shielding interaction is formulated as a mathematical model called stress shielding damage (SSD) model. SSD model used to…
Mn-based catalysts enable high NO x conversion in the selective catalytic reduction of NO x with NH3. Three catalyst-production methods, namely, co-precipitation, impregnation, and sol-gel, were used in this study to determine the optimum method and parameters. The maximum catalytic activity was found for the catalyst…
Ionomeric polymer transducers exhibit electromechanical coupling capabilities. The ion transport due to electric stimulus is the primary mechanism of actuation for a class of polymeric active materials known as ionomeric polymer transducers. In this article, a two-dimensional Monte Carlo simulation of ion hopping has…
It has been observed experimentally and computationally that a carbon nanotube with a large aspect ratio can self-fold because of the van der Waals force between parts of the same carbon nanotube. The primary issue in the self-folding problem is to determine the minimum threshold length of a carbon nanotube at which i…
The incorporation of gadolinium directly into nuclear fuel is important for improving the reactor behavior and satisfying the safety criteria during the core lifetime. MCNPX ( M onte C arlo N – P article code e x tended) has been used for designing Advanced Boiling Water Reactor model. MCNPX code based on Monte Carlo…
