Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
A Horizontal Impact Test System (HITS) will be developed to characterize several energy absorption mechanisms, i.e. axial splitting, tube inversion, deformation/expansion, axial folding, and flattening. There were two alternatives that has been developed for launching mechanism, i.e. spring and Hopkinson pressure bar…
The review deals with issues related to the theoretical analysis of the main relationship between the chemical structure of polymer and the response of various structural elements of this system to external mechanical effects at different temperatures and frequencies. The analysis is performed using the spectra of int…
This paper presents the technique with which Low frequency thermal cycling tests were carried out on two carbon steel. The steels used are low and medium carbon steel, the compositional analysis was done to ascertain the percentage of carbon the as-received materials contain, and the micrograph of the samples was done…
An advanced variable energy positron beam (~2 eV to 20 keV) has been designed, tested and utilized for coincidence Doppler broadening (CDB) measurements at the University of Texas at Arlington (UTA). A high efficiency solidified rare gas (Neon) moderator was used for the generation of a slow positron beam. The gamma r…
A method for synthesizing a unidirectional porous (UniPore) aluminum structure employing a cylindrical explosive compaction assembly is proposed and the condition for successful recovery is discussed. The microstructure of the compacted samples is demonstrated to show tight bonding between the walls with uniform pores…
The paper presents research results of polymethylmethacrylate (PMMA) combustion in a hybrid rocket engine (HRE) under the influence of an electrostatic field. It is shown that the main mechanism of electrostatic field influence on the combustion rate is process changes in the condensed phase.
The interaction of human serum albumin with Ethyl 2-[2-(dimethylamino)-4-(4-nitrophenyl)- 1,3-thiazole-5-yl]-2-oxoacetate was investigated by using isothermal titration UV-visible spectrophotometry in tris-buffer, pH 7.4. According to these results, it was found that there are a set of 4 binding sites for this ligand…
The nickel and manganese oxides (Ni-Mn oxides) were prepared by a simple co-precipitation process with sodium carbonate (Na2CO3) as precipitant. The products are the mixture of nickel oxides, manganese oxides and their solid solution. The phase and morphology of the synthesized product were characterized by X-ray diff…
We show that a disordered ensemble of dielectric particles near the Mie resonances has anomalous depolarizing properties. Under the first Kerker condition the depolarization length of circularly polarized light reaches its peak value, and can be ten times greater than the transport mean free path. The second Kerker co…
Composite layers on the basis of carbides and borides the titan and silicon on titanic alloy VT-1 are generated at diffused saturation in vacuum. Formation in a composite of MAX phase Ti 3 SiC 2 is shown. Thermodynamic research of phase equilibrium in systems Ti-Si-C and Ti-B-C in the conditions of high vacuum is exec…
Along With the accelerating aging process of china, the number of the elder continues to increase, and the development of the elder garment industry is imminent. However, with the rapid development of science and technology, the fabric of elder clothing is still unable to satisfy the actual needs of consumers. This th…
The work done experimentally explores generation of electron and x-ray radiation in the process of heating and cooling monolithic and iron-doped crystals of lithium niobate. Iron doping to the concentrations in the range of 10 23 m 3 was carried out by adding ferric oxide into the melt during the process of crystal gr…
This paper deals with experimental verification of reciprocal relations of nonlinear quadripole for unsteady mode in external magnetic field. We find out transients of measured voltages in the quadripole after current switch. These transients are caused by changing of current–voltage characteristics (CVC) of quadripol…
This paper studies how the addition and various content of Carbon nanotube (CNT) affecting the properties, especially the color difference of ethylene propylene diene rubber (EPDM)/ CaCO3 composites. The results show that the increased content of CNT can turn EPDM/CaCO3 composites from lighter, greener, and bluer to d…
Because the setting time of magnesium phosphate cement (MPC) was too quick, its further application was restricted. Influence factors about magnesium phosphate cement setting time are summarized and the influence laws are studied in the paper. The results show that with the increase of phosphorus to magnesium ratio (P…
The structure and electronic properties of the WS 2 /SiC van der Waals (vdW) heterostructures under the influence of normal strain and an external electric field have been investigated by the ab initio method. Our results reveal that the compressive strain has much influence on the band gap of the vdW heterostructures…
Research distribution the rolling moments symmetrical and asymmetrical report presents great importance both in theory and to introduce clarifications to the calculation of rolling resistance line assemblies. Clarifying individuals of metallic material deformation between the rolls single cylinder diameters act of any…
