The high quality single crystals of NpPd(5)Al(2) with the body-centered tetragonal structure were grown by the Pb flux method. NpPd(5)Al(2) was found to be the first Np-based heavy fermion superconductor with the relatively high critical temperature T(sc) = 4.9 K. The upper critical field H(c2) is large and highly ani…
The mol-ecule of the title compound, [CuNa(C(18)H(18)N(2)O(4))(C(2)N(3))(H(2)O)], is almost planar, the maximum deviation from the mol-ecular plane being 0.48 (4) Å. The coordination environment of the Cu(2+) ion is distorted square-planar and it is N(2)O(2)-chelated by the Schiff base ligand. The Na(+) cation has a d…

Abstract : This document reports the results of a three year program funded by the Strategic Environmental Research and Development Program (SERDP) to research, develop, and demonstrate military coatings systems that are hexavalent chromium free and use primers and topcoats with ultra low volatile organic compound (VO…
Contemporary approaches regarding to infrastructure are more and more directed to new materials development for natural gas and other installations.The most recent development and application of the new materials pertain to sealant materials for sealing of threaded joints in gas pipeline installations and installation…
Material exposure experiments are expected to present the material degradation under space environment. However, the exposure experiments can not be free from induced environments. Contamination from the International Space Station (ISS) produced the most readily change to the SM/MPAC&SEED samples, other than natural…

In the context of the methodological studies aimed to give a quantitative evaluation of composition basing on High Angle Annular Dark Field (HAADF) STEM imaging, I propose to afford quantitatively the effect of a strain field varying along the electron propagation direction. I propose, as a case study, the well known…
Investigations into the immunogenicity of the prion protein are ongoing. To combat its pathological isoform without affecting the cellular protein is a challenge in prion research. We here summarize the studies in which prion protein peptides have been used for immunization, to thus determine the most immunogenic part…
In this work, we studied the effects of Sn addition on the ordering temperature of FePt thin film. The coercivity of FePtSn film was about 1000 Oe greater than the coercivity of FePt film for an annealing temperature of $600^{\circ}C$ . Therefore, Sn addition was effective in promoting the $L1_0$ ordering and in reduc…
Pharmacological investigations were carried out with aqueous methanolic extract (AME) of Swietenia mahagoni (L.) Jacq. (Meliaceae) leaves. Acute toxicity studies revealed that the $LD_{50}$ dose of AME was 600 mg/kg, i.p. AME was found to possess significant anti-inflammatory activity in acute, sub-chronic and chronic…
In the centrosymmetric title compound, [Ni(C(8)H(8)NO(3)S)(2)(H(2)O)(4)], the Ni(II) ion, which lies on an inversion centre, is six coordinated by four water mol-ecules and two propionate O atoms from two 2-pyridylsulfanylpropionate N-oxide ligands, forming a slightly distorted octa-hedral geometry. An intra-molecular…

We develop a statistical model for a confined homopolymeric chain molecule based on a monomer grand ensemble representation. The molecule is subject to a confining external field, a backbone interaction, and an attractive interaction between any pair of monomers. An exact minimum principle for the thermodynamics of th…
Here, we present a microscopic theory to explain different Raman modes of the La0.5Ca0.5MnO3 based on the electronic Hamiltonian of the double-exchange model, which adds phonon interaction with the hybridization between the conduction electrons of the system and l-electrons. The spectral density is calculated by the G…
Cerium and silica co-doped nanoscale TiO2 particles were synthesized from a complex compound system of tetrabutyl titanate (TBT), tetraethyl orthosilicate (TEOS) and cerium nitrate hexahydrate (CNH) at 140℃.
