In this paper, low density polyethylene (LDPE)/calcium carbonate (CaCO3) nanocomposites were prepared both by Battenfeld screw extruder and vane extruder which is a kind of innovative equipment for polymer processing. Effects of the two processing equipment on the morphology, the thermal behaviour and the mechanical p…
Future fusion reactors, foreseen in the “European road map” such as DEMO, will operate under more demanding conditions compared to present devices. They will require high divertor and core radiation by impurity seeding to reduce heat loads on divertor target plates. In addition, DEMO will have to work at high core den…
The evaluation of surface-hardened depth (D) in induction-hardened steel is important in the guarantee of quality of the steel. If the size of the surface-hardened steel is large, a nondestructive evaluation method is required to inspect the D since destructive testing using, for example, a Vickers hardness tester, be…
Silicon dioxide thin film was prepared by thermal growth method and PMMA film layer was prepared by spin coating.Silane coupling agent octadecyltrichlorosilane (OTS) be used to modified the surface of SiO2.The result of atomic force microscope (AFM) showed that using PMMA and OTS modified SiO2 layer can effectively im…
Tin dioxide nanoparticles were synthesized by solgel method and calcined at dierent temperatures in the range 350750 C. The SnO2 precursor solution was prepared from SnCl22H2O (tin (II) chloride dihydrate), and chloride ions were removed from the solution before the solgel synthesis was applied. SnO2 powders were char…

Physical disruption of cellular membranes arising from interactions with engineered nanoparticles is an important, but poorly understood aspect of nanotoxicology and nanomedicine. Model cellular membranes (i.e. lipid bilayers) can be used to identify interaction mechanisms, and most studies have largely focused on lip…
Significance and Use 5.1 Measurement results from this test method assists in demonstrating regulatory compliance in such areas as safeguards SNM inventory control, criticality control, waste disposal, and decontamination and decommissioning (D&D). Th
To consolidate the safety assessment for liquid-metal fast breeder reactors (LMFBRs), hypothetical core disruptive accident (HCDA) sequences have been extensively studied over the past decades. Numerous analyses of the so-called initiating phase (or primary phase) of a HCDA have been made with the safety analysis syst…
Significance and Use 5.1 The tendency of a fuel to vaporize in automotive engine fuel systems is indicated by the vapor-liquid ratio of the fuel. 5.2 Automotive fuel specifications generally include T (V/L = 20) limits to ensure products of suitable vola
The idea on a homogeneous nuclear reactor, first suggested by Ya B Zeldovich and Yu B Khariton in 1939, has since had its ups and downs and is now re-emerging, enriched with the knowledge and experience accumulated over the years having past. One of the current versions of the idea, the fast molten-salt reactor with a…
Optically active organic chromophores have attracted much interest in recent years for their potential for use in photonic devices. Chromophores such as compound (1) have been found to have a very high second order nonlinear susceptibility ( β ) value of 650 × 10⁻³⁰esu in dimethyl formamide.¹ The performance of 1 in a…
This specification covers the standards for the types, physical properties and dimensions of cellular polystyrene boards with or without facings or coatings made by molding (EPS) or extrusion (XPS) of expandable polystyrene proposed for use as thermal insulation. This specification, however, does not cover laminated p…
Molecular imprinted polymer (MIP) for melamine has been fabricated using precipitation polymerization method using methacrylamide and 9-vinylcarbazole. The molecular imprinted polymer was characterized using Fourier transform infrared spectroscopy, thermo gravimetric analysis, photon cross correlation spectroscopy ana…
Liquid metals have excellent properties to be used as heat transport fluids due to their high thermal conductivity and their wide applicable temperature range. The latter issue can be used to go beyond limitations of existing thermal solar energy systems. Furthermore, the direct energy converter Alkali Metal Thermo El…
The article provides the context for finding out how van der Waals model is applied to describe average spectral-response characteristics of interatomic dipoles of metals with bcc and fcc crystal lattice. The formula for emission ability from crystal surface has been discovered and changes for electronic contribution…
