In this work, nanocomposites were obtained by mixing an unsaturated polyester resin with a sodium montmorillonite slurry. Procedure by steps was clay slurry and polyester resin were stirring and subsequently monomer, initiator and catalyst were added to induce the cross-linking reaction. As comparative with pristine r…
Chromium Carbide composite coating has been the subject of interest in the area of nano material due to the improvement in mechanical properties when grain sizes reduce to nanometer scale.. Composite coating of chromium carbide has used in integrated printed circuit boards (PCBs), pins for dot-printers, corrosion resi…
Efforts are being made to increase the efficiency and decrease the cost of vitrifying radioactive waste stored in tanks at the US Department of Energy’s Hanford Site in Washington State. The compositions of acceptable and processable high-level waste (HLW) glasses need to be optimized to minimize the glass volume and,…
The rheological behaviour and morphology of in-reactor alloy of Polypropylene (PP)/Ethylene Propylene Rubber (EPR) synthesized by splitting the monomer feeding to copolymerization reactor are studied in this article. The Scanning Electron Microscopy (SEM) and oscillation rheometry were used to determine relationship b…
We propose the construction of a photocathode electron gun test facility for the characterisation of electron bunches emitted from a GaAs photocathode at room temperature and at LN2 (77 K) temperature, offering diagnostic capa- bilities to measure beam emittance and photocathode re- sponse time as a function of quantu…
Continuous monitoring of fluids in medical tubing is desired for point-of-care clinical diagnostics. In this work, we incorporate a nanostructured surface-enhanced Raman scattering (SERS) sensor into flexible tubing commonly used for intravenous drug delivery and urinary catheters. We investigate the detection of prom…
A pile foundation plays an important role in case of heavy lateral loads due to earthquakes, wind, wave etc. The pile caps which are often massive and deeply buried would be expected to provide significant resistance under the lateral loads. The few previous studies indicate that the lateral load resistance provided b…
This paper examines the efficacy and efficiency of the Waste Isolation Pilot Project (WIPP) of DOE with respect to the disposal of transuranic (TRU) waste. It will present an evaluation of the science, engineering, and operations management of WIPP starting from the pre-regulatory period and going through 2010. As WIP…
During exercise and in hot environments, the main cooling mechanism is through sweat evaporation. However, clothing can disrupt evaporation, which leads to decreased performance and in some cases can lead to heat illness. New fabrics and designs have been introduced with the purpose of improving thermoregulatory prope…
The present study addresses the relationship between the presence of some salts in crude oil and the corrosion of metallic equipments in the context of the petroleum refining industry. The rate of corrosion of iron in water containing CaCl2 and MgCl2 with concentrations similar to those in the water present in crude o…
The evaluation of uncertainties of radiological characteristics of low and intermediate level waste is a challenging issue for the global radioactive waste management community. One of the goals of ONDRAF/NIRAS as Belgian waste management agency is to propose a strategy that is applicable for all Belgian radioactive w…
Decomposition of acetylene / Co(CO)(3)(NO)mixtures induced by excimer ArF laser pulses is an efficient technique for preparation of amorphous cobalt nanoparticles encapsulated in carbon. Vacuum heating up to 900 degrees C leads to crystallization the metal core. The cobalt core crystallizes in a face-centered cubic (b…
The experimental investigation of the influence of time-dependent, thermal and mechanical factors on the kinetics of martensite transformation has been performed in the austenitic chromium-nickel steels. Additionally, the effects of martensite transformation on the mechanical properties are studied and the nature of s…
We consider the optical properties of composites containing metamaterial inclusions in a normal material matrix, with the scale size of inclusions much finer than the wavelength. We consider the case where these inclusions have sharp corners, and use analytic results of Hetherington and Thorpe to argue that it is then…
In Germany anhydrous MgSO4 (SVV) is considered as potential sealing material for the isolation of High-LevelWaste (HLW) in salt rock. When brine approaches the sealing material (SVV), different MgSO4-hydrates along with other mineral phases (e.g. bloedite) form, removing free water from the solution. This leads to a s…
We present a theoretical study on the extraordinary optical transmission through square hole arrays in a metal film, focusing on the dependence on the metal thickness. More precisely, we will study the crossover from the (now canonical) optically thick films to the case of optically thin films. We show that, as the th…
Metal-organic frameworks (MOFs) represent an extensive class of porous crystals in which organic ‘struts’ are linked by metal oxide units to make an open networks. The flexibility with which their building units can be varied and their ultra-high porosity (up to 10,000 m2/g) have led to many applications in gas storag…
Development of a new mathematical framework for constructing parallel algorithms for lattice kinetic Monte Carlo (kMC) simulations, that covers pre-existing methods.
New semiconductor structures for nanoelectronics require silicon-compatible with existing silicon technology, even though the carbon nanotubes are subsidized and functional feroic and semiconducting.To modify the properties of silicon nanotubes, semiconducting properties of their structures, we applied to solid state…
The suite of hot-cells at the Windscale Laboratories of the UK National Nuclear Laboratory (NNL) is both extensive and a particularly flexible plant. It is able to co-process a variety of irradiated fuels and other radioactive materials on a semi-industrial scale for purposes additional to ‘traditional’ Post Irradiati…
