Propane conversion to propylene has been the subject of intensive researches. This is due to the increasing demand for propylene. Current propylene production processes suffer from several limitations. Oxidative dehydrogenation (ODH) is a promising alternative technology for propylene production overcoming the drawbac…
Overheating is a common problem both with the use of active and passive solar energy in solar thermal energy systems and in highly glazed buildings. In solar thermal collectors, the elevated temperatures occurring during stagnation result in reduced lifetime of the collector materials. Highly glazed building facades p…
The Korea nuclear industry has been developing the thermal-hydraulic system analysis Safety and Performance Analysis CodE (SPACE) and the GAs Multicomponent Mixture Analysis (GAMMA) code for safety analysis of pressurized water reactors (PWRs) and high-temperature gas-cooled reactors (HTGRs), respectively. SPACE will…
Uncooled infrared focal plane arrays are being developed for a wide range of thermal imaging applications. A new type of detector for middle and long wave applications was developed based on amorphous silicon VGA device. This new detector is well adapted for gas detection, high temperature measurements, and special in…
The title compound, a chain adduct of molybdenum(II) acetate with 1,2-bis(4-pyridyl)ethane (bpe), catena(tetrakis(μ-acetato-O,O′)(μ-1,2-bis(4-pyridyl)ethane-N,N′)dimolybdenum(II)), [Mo2(CH3CO2)4(bpe)]n, was synthesized, and the crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. I…
In the present study, the single layer Co90Fe10 and X/Co90Fe10 (X = Cu, Cr, Au, Ni80Fe20) double layer films were investigated. Films were fabricated by DC magnetron sputtering at room temperature on Si substrates. In order to improve the soft magnetic properties of CoFe films, four different underlayers were examined…
Although carbon has been widely used in catalytic processes as a support material, very little is known about its function as an active catalyst. The scientific challenge is to achieve a detailed mechanistic understanding of the structural or chemical sites of the carbon that are catalytically active especially becaus…
Crystal rotation due to cold rolling was investigated on commercial 1050 aluminum. A 3-mm-thick specimen was annealed at 803 K for 3.6 ks. The surface of the specimen was electro-polished and then observed using a scanning electron microscope (SEM)-electron backscatter diffraction (EBSD) system. Cold rolling to about…
Kerat ins are the most abundant proteins in epithelial cells of vertebrates and represent the major constituents of skin and its appendages such as nail, hair, feather, and wool. World-wide poultry processing plants are producing millions of tons of feathers as waste products annually, wh ich consist of approximately…
The crystal structure of compound [Co2(C14H12N2O2)2] showed dimeric complex.Two nitrogen atoms and two oxygen atoms of the [N,Nbis(salicylidine)diamine] formed distorted square pyramidal geometry in the region of Co(II) and one oxygen atom from each ligand acting as bridge between two ligand molecules which are distor…
It is important to understand the characteristics of explosive sympathetic detonation for explosive safety.Sympathetic reaction test of GHL(RDX/Al/Binder)explosive charges with shell are conducted.A model of the sympathetic reaction test is established.The elements-apart method and nodes random-failure method are used…

The Ti(C,N)precipitation and texture evolution in ultra-low carbon Ti-bearing enamel steel were studied to discover their correlation.Two different cooling paths of simulative coiling were adopted to gain different morphologies of Ti(C,N)precipitate in hot strips.It is found that the Ti(C,N)precipitate in hot strip us…
In this study, the preliminary results of the physical-mechanical characterization of new hemp-based composites, obtained by using alternative binders with very reduced environmental impact, are reported.
We have proposed a novel surface plasmonic nanolaser based on a nanowire/air gap/metal thin film hybrid structure to carry out theoretical research and simulation analysis. Opening an air groove in the MgF2 insulating layer, then making a nanowire embedded on the top of the air slot but maintaining a gap between the n…
Oxidation of 2-methylindoles 12a-f with dimethyldioxirane (DMD) revealed that N-unprotected 12b,f and protected N-carbamate 2-methylindole 12c afforded indoxyls 16b,c and o-(N-propionyl)aminobenzoic acid 17f as the main products, while N-alkylor N-aryl-2-methylindoles 12a,d,e gave 1,5'-diphenyl-4',5'-dihydro-3'H-spiro…
The paper describes the synthesis of nanocrystalline zinc ferrite starting from 1,4-butanediol and a mixture of zinc and iron nitrates.During the heating of the obtained solution, a redox reaction takes place with emission of brown nitrogen oxides and formation of a solid powder.This powder was characterized by therma…
An automated geometric characterisation tool for woven reinforcement textiles has been developed and is presented. This tool is used to obtain the in-plane geometry of woven textiles. The image of the textile is captured using a standard office scanner, eliminating the need for complex set up and specialised equipment…
