The presence of O during the chemical vapour deposition (CVD) of B‐doped diamond results in the suppression of B incorporation into the diamond film. In this study, we demonstrate that the amount of residual O within the chamber is higher at the beginning of the diamond growth due to the O‐contaminated chamber walls,…
In this paper, a novel compact high-voltage (HV) test system based on a magnetically controlled resonant transformer (MCRT) is proposed. This system is used to perform a power-frequency HV on-site voltage withstanding test. First, the basic principle of the MCRT is introduced. Next, a Fourier analysis based on the equ…
The present work reports the synthesis of dip coated MgO nanoflower thin films. The films are developed without employing any capping agent and catalyst. A simple chemical deposition technique is adopted for this purpose. The MgO nanoflower thin films are characterised by X-ray diffraction, field emission scanning ele…
Herein, we report progress towards realization of vascular stents that will eventually provide opportunity for evaluating cellular response to rationally-designed, submicrometer-scale surface patterning in physiologically-relevant contexts, i.e. those that provide exposure to the complex multicellular milieu, flow-ind…
Triboluminescence (TL) has gained increasing attention in the past two decades due to its potential for many applications such as an in situ damage sensor, X-ray source, spectroscopic probe, and optical switch. So far the mechanisms by which TL is excited are not well understood. We have investigated the TL emitted du…
Crystal structure and magnetic properties have been studied for bulk MnFePSi compounds prepared by the spark plasma sintering method. The effect of Si content on the crystal structure and the magnetic properties of the compounds were investigated. The MnFePSi compounds crystallize in a hexagonal Fe2P-type structure wi…
Crystal structure and magnetic ordering in ${\mathrm{YMn}}_{3}{\mathrm{Al}}_{4}{\mathrm{O}}_{12}$ are determined by neutron powder diffraction measurement, indicating that $S=2$ spins of the ${A}^{\ensuremath{'}}$-site ${\mathrm{Mn}}^{3+}$ ions are ordered in G-type antiferromagnetic (AFM) arrangement in the $Im\overl…
Polypropylene was synthesized with a fourth generation of Ziegler—Natta catalyst and in the presence of mixed and individual external donors, namely cyclohexyl dimethoxymethylsilane and dicyclopenthyl dimethoxysilane. A synergic effect on molecular weight and polydispersity index and changes in crystallinity and cryst…
Crystalline nanoparticles (NPs) of semiconductor materials have been attracting huge research interest due to their potential use in future applications like photovoltaics and bioimaging. The important role that intentional impurity doping plays in semiconductor technology has ignited a great deal of research effort a…
Surface modification of jute fibers is necessary to improve the adhesion and interfacial compatibility between fibers and resin matrix before using fibers in polymer composites. In this study, dodecyl gallate (DG) was enzymatically grafted onto the jute fiber by laccase to endow the fiber with hydrophobicity. A hand l…
In this study, the effect of solution pH on the electrochemical behaviour of AISI 304 austenitic and AISI 430 ferritic stainless steels at open circuit potential (OCP) in concentrated acidic solutions was studied. Polarization curves showed that the corrosion current density of both stainless steels increased with dec…
Carbon nanotubes (CNTs) were prepared by chemical vapor catalytic deposition using the Fe-Ni-Mo/MgO catalyst prepared by sol-gel. The effect of the dosage of citric acid on the activity of Fe-Ni-Mo/MgO catalyst for CNT synthesis was studied. The results showed that the dosage of citric acid greatly affected the activi…
A second locality of the milarite-group mineral brannockite (ideally KLi 3 Sn 2 Si 12 O 30 ) has been discovered at Liberty Bell/Washington Pass in the alkaline granite of the Golden Horn Batholith, Okanogan County, Washington, USA as sub-millimeter euhedral bladed clear crystals in a single miarolitic cavity in a bio…
A novel clay-silane coupling agent-polymer hybrid material based on polyvinyl acetate (PVAc)–organophilic montmorillonite (OMMT) and 3-methacryloxypropyltrimethoxysilane (KH570) has been prepared via in situ emulsion polymerization and studied the influence of KH570 on thermostability, tensile behavior and water resis…
Organic nanolayers attract much attention for the isolation and adhesion promotion of the Cu line and insulator in Cu interconnection of microelectronic devices. This paper proposes a strategy for selective formation of adhesion nanolayer on the insulator surface with etching it on Cu surface by Cu-oxide-assisted pyro…
As is evident from numerous investigations, drug-eluting vascular grafts and stents have not solved the main problems associated with thrombosis and due to drug release only postpone their advance for a longer period. Here we point to a potential solution of this problem by developing thrombolytic sol-gel coatings whi…
The present study aims to synthesize SiAlON-based composites utilizing coal gangue. Different types of SiAlON-based composites were synthesized using coal gangue by carbothermal reduction nitridation method through control of different reaction atmospheres. The experimental results indicate that the oxygen partial pre…
We experimentally demonstrate temperature-tuned and gain-assisted surface-plasmonic coherent perfect absorbers. In these devices, coherent perfect absorption (CPA) is supported by balancing the absorber's radiative and non-radiative decay rates under thermal tuning of free-electron collision frequency in the Ag layer…
The effects of epoxy‐functionalized glass fiber (GF) on the electrical conductivity, crystallization behavior, thermal stability, and dynamic mechanical properties of polyoxymethylene (POM)/thermoplastic polyurethane (TPU)/multiwalled carbon nanotube (MWCNT) composites are investigated. The electrical resistivities of…
This paper examines the oxidation reaction of tert-amyl methyl ether (TAME), an oxygenated fuel additive, with chlorine radical initiators in the presence of oxygen. Data are collected at 298, 550, and 700 K. Reaction intermediates and products are probed by a multiplexed chemical kinetics synchrotron photoionization…
