Boron nitride nanosheets (BNNSs) are attractive 2-dimensional nanomaterials with excellent thermal conductivity, mechanical properties, and thermal stability. It is therefore significant to develop new simple methods to produce BNNSs. In this study, BNNSs with nanometer thicknesses and diameters of several hundreds of…
By controlling the conditions for corrosion of V-based electrodes, stable cycling of 500 mAh g −1 for up to 300 cycles is achieved.
The pin power density is an important quantity which has to be monitored during the reactor operation, for two main reasons. Firstly, it is part of the limits and conditions of safe operation and, secondly, it is source term in neutron transport calculations used for the adequate assessing of the state of core structu…
The concern about the thermal performance of microelectronics is on the increase due to recent over-heating induced failures which have led to product recalls. Removal of excess heat from microelectronic systems with the use of heat sinks could improve thermal efficiency of the system. The shape of the heat sink model…
The ANSWERS Software Service is developing a number of techniques to better understand and quantify uncertainty on calculations of the neutron multiplication factor, k-effective, in nuclear fuel and other systems containing fissile material. The uncertainty on the calculated k-effective arises from a number of sources…
Vietnamese coconut shell char was activated by steam and carbon dioxide at low temperatures with the presence of K2CO3 as a catalyst. The effects of process parameters on adsorption capability of the product including different ratio of impregnation of activation agents, activation temperature, activation time were in…
This work evaluates the effectiveness of nanoscale particulates in producing non-Einstein-like responses in polymer matrices, to reduce their negative effects in low shear rate processing. This is of value to material processing applications which encompass extrusion, flow into cold mold, and generalized processing of…
The experimental setup GRAPhEME (GeRmanium array for Actinides PrEcise MEasurements) has been used at GELINA (EC-JRC, Geel, Belgium) to perform (n,xn γ) cross sections measurements. GRAPhEME has been especially designed to take into account the specific difficulties generated by the use of actinides samples. This work…
Gadobutrol is a gadolinium (Gd)-based contrast agent for magnetic resonance imaging (MRI). In India, gadobutrol is approved for MRI of the central nervous system (CNS), liver, kidneys, breast and for MR angiography for patients 2 years and older. The standard dose for all age groups is 0.1 mmol/kg body weight. The saf…
Nanosphere lithography is a low-cost technique for nanopatterning large-area samples. In this work, a more sophisticated version of this method is presented, which expands the number of possible fabricable structures. It is shown, how tailored nanostructures can be written in a highly parallelized way. By fabricating…
Adiabatic shear banding (ASB) is a dynamic localization phenomenon resulting from thermomechanical instability under high strain rate and low stress triaxiality loading conditions. High strength, steels and lightweight alloys of titanium and aluminum are highly susceptible to this phenomenon which leads to premature m…
In this paper, fatigue damage predictions by six models were compared with three-point bending experimental results carried out on composite materials subjected to an ergodic Gaussian and stationary random (EGSR) signal. Due to the complexity of fracture modes and their interactions, we have focused on the delaminatio…
Nanotechnology is currently gained increased attention in various fields of science and technology like imaging, sensing, targeted drug delivery, gene delivery systems and artificial implants which is increasing the commercial usage of products including drugs in the various parts of the world. Because of their extens…
ZIF-8@Polyacrylate carboxyl super-macroporous microspheres was synthesized by insitu growth method with the ZIF-8 nanoparticles loaded on the surface of PC-SMM for adsorptive removal of Malachite Green (MG) from water. The as-synthesized ZIF-8@PC-SMM was characterized by SEM and XRD experiments, and the adsorption kin…
The influence of various modes of thermal cycling treatment on the microstructure and properties of ferromagnetic alloy Ni47Mn42In11 was studied. The modes of thermal cycling treatment differed in the heating temperature (363 – 573 K) and holding time, the cooling temperature being 77 K for all modes. The number of he…
This paper aims to analyse the effects of corrosion atmosphere on sintered stainless-steel specimens. In particular, it is intended to assess a relation existing between weight and corrosion resistance, density and corrosion resistance, tensile properties and corrosion resistance. Three groups of sintered stainless st…
Some catalysts of CO oxidation on silumin alloy AK12M2, used for the manufacture of pistons for Russian cars were investigated. The catalysts were prepared by the method of plasma electrolytic oxidation of silumin in electrolytes of various compositions with further activation by the salts Ce, Cu, Co, Ni, Mn and Al. T…
Carbon-fiber-reinforced cement-based (CFRC) composites is a promising functional material which can be used both in the military and civil fields against electromagnetic interference. However, it is essential to make carbon fibers dispersed uniformly during the preparation of CFRC. In this work, short carbon fibers we…
Kurchatovite occurs as colorless granular crystals up to 1 mm at the Fuka mine, Okayama Prefecture, Japan. The mineral is associated with shimazakiite, calcite and johnbaumite. The Vickers microhardness is 441 kg mm−2 (50 g load), corresponding to 4½ on the Mohs’ scale. The calculated density is 3.23 g cm−3. Electron…
