Applying thermophotovoltaics (TPV) to present energy production technologies allows us to increase energy output while utilizing existing infrastructure by reclaiming the heat lost during the production process. In order to maximize the efficiency of these sources, the conversion efficiency of the TPV system needs to…

The use of dual compatibilizers, poly (2-ethyl-2-oxazoline) (PEOX) and polymeric methylene diphenyl diisocyanate (pMDI) in Novatein thermoplastic protein from bloodmeal (NTP) and PBS blends were investigated. A composition of 50% of NTP was used for all formulations with different percentage compatibilizer. Mechanical…
The local efficiency parameters of readily processed solar cells can be investigated both by applying dark lock-in thermography (DLIT) and Solar Cell Local characterization (CELLO), which is a special bias-dependent lock-in variant of light beam-induced current (LBIC) imaging. While the DLIT investigation directly lea…
The Radiation Embrittlement Archive Project (REAP), which is being conducted by the Probabilistic Integrity Safety Assessment (PISA) Program at Oak Ridge National Laboratory under funding from the U.S. Nuclear Regulatory Commission s (NRC) Office of Nuclear Regulatory Research, aims to provide an archival source of in…
SCALE 6.2 provides numerous updates in nuclear data, nuclear data processing, and computational tools utilized in the criticality safety calculational sequences relative to SCALE 6.1. A new 252-group ENDF/B-VII.0 multigroup neutron library, improved ENDF/B-VII.0 continuous energy data, as well as the previously deploy…
The advent of nanotechnology in medicine has raised several new prospects in the improvement of diagnosis and treatment of human diseases. Nanoparticles are finding their way into biology in the form of drug carriers. The physical sizes of nanomaterials create a strong possibility for their interactions with biologica…
As the only truly agricultural and great economic domesticated insect, the silkworm is not only value as a model for genetics and rmolecular biology research, but it also has great value for new silk materials. Induction and regulation of trimolter induced by anti-juvenile hormone have shown vast potential to be signi…
Neutron resonance densitometry (NRD) has been proposed to quantify nuclear materials in particle-like debris of melted fuel formed in a severe accident of nuclear reactors such as the Fukushima Daiichi nuclear power plants. NRD is a method that combines NRTA (neutron resonance transmission analysis) and NRCA (neutron…
Loading of inorganic fillers in paper decreases the inter-fibre bonding and paper strength. To overcome the reduction in paper strength, preflocculated talc filler was investigated using different doses of commercial cationic starch, with the cooked starch being added to the talc slurry under controlled conditions. Th…
Ferritic-martensitic (FM) steel Grade 92, with or without thermomechanical treatment (TMT), and austenitic stainless steels HT-UPS (high-temperature ultrafine precipitate strengthening) and NF709 were selected as potential candidate structural materials in the U.S. Sodium-cooled Fast Reactor (SFR) program. The objecti…
Polycaprolactone (PCL) and natural rubber (NR) blends were prepared using a melt blending process, in the absence and presence of an organic peroxide crosslinking agent. The resulting blends were then characterised for their functional groups using Fourier transform infrared analysis (FTIR), surface morphology using s…
Background: Polymorphism is the phenomena where drug exists in more than one crystalline form. Though polymorphs are chemically identical, they exhibit different physicochemical properties like melting point, solubility, dissolution profile etc. which further affect the biological properties of drugs. The purpose of t…
The stress potential function theory for the plane elasticity of octagonal quasicrystals is developed. By introducing stress functions, a large number of basic equations involving the elasticity of octagonal quasicrystals are reduced to a single partial differential equation. Furthermore, we develop the complex variab…
Streszczenie: W artykule przedstawiono i omowiono problematyke związaną z powszechnym stosowaniem materialow polimerowych, ktore mimo wielu swoich zalet charakteryzują sie szacunkowo niską odpornością na dzialanie ognia. Omowiono mozliwości podwyzszenia odporności na dzialanie ognia poprzez dodatek do tworzywa sztuczn…
Emission characteristics of a heavy-duty diesel engine operating on neat gas-to-liquids GTL (1&2) of different fuel characteristics were investigated and a comparison was made with those of diesel fuel. The effect of GTL on the emissions of a heavy duty diesel engine was carried out. The results showed that the engine…

Key words: chitosan, mechanical properties, paper, oil palm pulp The application of chitosan as an additive in papermaking to improve the strength and water resistant properties is described. Unbleached sulphate pulp from oil palm stem was treated with chitosan. The chitosan was prepared in the laboratory using the ch…
As the using of reinforced concrete shells structures with opening have many advantages that they permit to cover large area without using intermediate supports. They have light weights and require minimum amounts of material that it is required small thicknesses comparing to their spans. This investigation is carried…
In this research electrochemical studies were performed on stainless steels and compared to Cunifer, Monel and Alloy 59 in 3.5% NaCl solution at (22±2) °C and (50±2) °C at 200 rpm.Those materials have been evaluated using weight loss, Tafel polarization, cyclic polarization and scanning electron microscopy techniques.…
