This paper describes the preparation of a new precursor for incorporating phosphate into a LiMn2O4 spinel-like cathode material. This novel precursor is characterized using FTIR, UV–vis, ATD/TG/DSC, CHN elemental analyses, TEM–EDS and SEM–EDS techniques. The proposed strategy involves forming a Li–NH4–Mn(III)–citrate…
Chromium thin films were deposited on 304 stainless steel using the hollow cathode discharge (HCD) method. Chromium films were implanted with nitrogen ions at different energies ((15-25-35-45) keV) and at a dose of 5×10 17 ions/cm 2 . The implanted films were characterized using x-ray diffraction (XRD), atomic force m…
Quantum dots (QDs) are of great interest due to their unique chemical and physical properties. Recently, a hot start (HS) polymerase chain reaction (PCR) amplification performance based on QDs with a high-fidelity Pfu DNA polymerase has been reported. However, whether QDs can trigger HS effects with other high-fidelit…
SiO2 nanolayer coated cubic boron nitride (cBN), cBN(core)/SiO2(shell) powder, was prepared by rotary chemical vapor deposition. The cBN/SiO2 powder was densified by spark plasma sintering at 1873 K for 0.3 ks. The hexagonal boron nitride (hBN) phase was not observed in the cBN–SiO2 composites, indicating that the SiO…
The discovery of novel m aterials that can be active, selective and stable catalysts for the efficient transformation of organic molecules to useful products is of high importance. In recent years, there has been significant interest in the utilisation of supported gold-based nanoparticles that can be effective cataly…
Mesoporous structures can increase catalytic activity by maximizing the ratio of surface area to volume, but current synthesis techniques utilize expensive polymers and toxic chemicals. A Geobacter sulfurreducens biofilm was used as a sustainable template to form mesoporous Pd structures while eliminating the need for…
Abstract An indigenously developed low‐cost clay‐alumina‐based ceramic microfiltration membrane of 19‐channel configuration has been evaluated for degumming, dewaxing and deacidification of rice bran oil (RBO) miscella having different oil contents at pilot scale. Rice bran wax and soap particles in miscella will aggr…
Microbial metalloenzymes constitute a large library of biocatalysts, a number of which have already been shown to catalyze the breakdown of toxic chemicals or industrially relevant chemical transformations. However, while there is considerable interest in harnessing these catalysts for biotechnology, for many of the e…
Common salt (sodium chloride) and chemical preservatives are used for preservation of skins and leather to protect from microbial attacks, which leads to severe pollution problem. Bacteriocin is an eco-friendly option for skin and leather preservation in leather industry, which contains antimicrobial and antifungal co…
Original scientific paper The paper deals with the stress state analysis of the cycloid disc by using numerical and experimental methods for the most critical case of the meshing-single meshing. Cycloid disc is the vital element of the cycloidal speed reducer- mechanical power transmission of the new generation with g…
Study of Aluminum nitride (AlN) thin film deposited on silicon wafer and glass substrates by DC magnetron sputtering technique at different power variation. The X-ray diffraction and Fourier transform infrared spectroscopy (FTIR) study revealed the formation of the AlN phase. The optical characteristics of films, such…
The rare and highly aggressive adult soft tissue sarcomas leiomyosarcoma (LMS) and undifferentiated pleomorphic sarcoma (UPS) contain complex genomes characterized by a multitude of rearrangements, amplifications, and deletions. Differential diagnosis remains a challenge. MicroRNA (miRNA) profiling was conducted on a…
AIMS: Acute lung injury (ALI) induced by excessive hyperoxia has been employed as a model of oxidative stress imitating acute respiratory distress syndrome. Under hyperoxic conditions, overloading quantities of reactive oxygen species (ROS) are generated in both lung epithelial and endothelial cells, leading to ALI. S…
Nanocrystalline (Average grain size ∼200 nm) bulk AA2124 alloy was produced through high energy ball milling of microcrystalline powder followed by spark plasma sintering (SPS) at 480 °C with a holding time of 10 min. The effect of initial particle and grain size on the microstructural evolution as well as on the rela…
The evolution of pressure drop, drainage rate, saturation, and efficiency of combined philic, and phobic oil mist filters in real‐time are examined. The experiments used four different filter configurations, with a combination of oleophobic and oleophilic fibrous filter media, and one oleophilic only reference. The ef…
The ability of many copper metalloenzymes to activate O2 and transfer it to organic substrates has motivated extensive attention in the literature. Investigations focusing on synthetic analogues have provided a detailed understanding of the structures of potential intermediates, thereby helping to guide mechanistic st…
Nano-graphite/Fe3O4 composite (NG/FC) synthesized through deposition–precipitation method, was developed for the removal of methyl violet (MV) from aqueous solution. The parameters including pH, temperature and shaking time on MV removal efficiency were extensively investigated. The adsorption of MV increased smoothly…
Abstract Cu 2 ZnSnS 4 (CZTS)‐based materials have a useful band gap and a high absorption coefficient; however, their power conversion efficiency is low compared with that of CdTe and Cu(In,Ga)Se 2 ‐based solar cells. Two of the factors that strongly affect CZTS solar cell characteristics are the MoS 2 layer and the p…
Smart garments for monitoring physiological and biomechanical signals of the human body are key sensors for personalized healthcare. However, they typically require bulky battery packs or have to be plugged into an electric plug in order to operate. Thus, a smart shirt that can extract energy from human body motions t…
Al doped ZnO thin films were synthesized by ultrasonic spray pyrolysis technique. The concentration ratio of [Al]/[Zn] was varied from 1 to 5 %mol in the starting solution, in order to investigate the effect of doping ratio on the structural optical and electrical films properties. The films thicknesse was found in th…
