Bismuth (Bi)-doped optical fibers are of great interest because of the broad luminescence offered by them. These fibers have huge potential to develop lasers and amplifiers in wavelength bands uncovered by the rare earth (RE)-doped materials such as Ytterbium, Erbium, and Thulium. Bi-doped aluminosilicate, phosphosili…
Measurements of magnetic susceptibility χ as a function of temperature (from 2 to 300 K) were made on polycrystalline samples of the compounds Cu 2 MnSiS 4 , Cu 2 MnGeS 4 , Cu 2 MnSnS 4 , Cu 2 FeSiS 4 and Cu 2 FeGeS 4 . From the 1/ χ versus T curves, it was concluded that the samples were antiferromagnetic. These curv…
In this paper, we present a simple effective numerical geometric method to estimate the divergence of a vector field over a curved surface. The conservation law is an important principle in physics and mathematics. However, many well-known numerical methods for solving diffusion equations do not obey conservation laws…
Using ultraviolet photon pulses, we have probed the internal behavior of a molybdenum-gold Magnetic Penetration Thermometer (MPT) that we designed for x-ray microcalorimetry. In this low-temperature detector, the diamagnetic response of a superconducting MoAu bilayer is used to sense temperature changes in response to…
Abstract Two major models, namely direct and indirect models, have been proposed for the protein chemical denaturation but it remains challenging to experimentally demonstrate and distinguish between them. Here, by use of CD and NMR spectroscopy, we succeeded in differentiating the effects on a small but well-folded p…
The research about Waste of Corn as Substrate In Produce Poly-β-Hydroxy Butyrate (PHB) by Bacterial Isolates Origin Sugar Factory Arasoe Bone. The research purpose to determine the ability of bacterial isolates from sugar mills Arasoe Bone is BA9 and MA4 and nitrogen concentration optimal for producing the PHB. With u…
Neste trabalho, apresentamos um estudo da reacao do ciano (CN) com a molecula C 2 H 2 . Mais precisamente, determinamos as geometrias, frequencias e energias eletronicas para as diferentes especies envolvidas nos caminhos de reacao do processo CN + C 2 H 2 usando o nivel de calculo M06L/ 6-311++G(d,p). A partir deste…
In this letter we study the valley degeneracy splitting of the transition-metal dichalcogenides monolayer by first-principles calculations. The local magnetic moments are introduced into the system when the transition-metal atoms are adsorbed to the monolayer surface. Zeeman effect arising from the local magnetic mome…
The first portion of this report provides a detailed description of fiscal year (FY) 2015 test result corrections and analysis updates based on FY 2016 updates to the Cyclic Integrated Reversible-Bending Fatigue Tester (CIRFT) program methodology, which is used to evaluate the vibration integrity of spent nuclear fuel…
Abstract Decellularised human livers are considered the perfect ECM (extracellular matrix) surrogate because both 3-dimensional architecture and biological features of the hepatic microenvironment are thought to be preserved. However, donor human livers are in chronically short supply, both for transplantation or as d…
Hybrid or metal organic framework (MOF) perovskites of general composition,\nABX$_3$, are known to show interesting properties which can lead to variety of\ntechnological applications. Our first principles study shows they are also\npotential candidates for exhibiting cooperative spin-state transitions upon\napplicati…
We find that generic boundary conditions of Weyl semimetal is dictated by only a single real parameter, in the continuum limit. We determine how the energy dispersions (the Fermi arcs) and the wave functions of edge states depend on this parameter. Lattice models are found to be consistent with our generic observation…
In the present work the Buildup factor for gamma rays were studied in shields from epoxy reinforced by lead powder and by aluminum powder, for NaI(Tl) scintillation detector size ( ×? ), using two radioactive sources (Co-60 and Cs-137). The shields which are used (epoxy reinforced by lead powder with concentration (10…
The physical phenomenon of neutrons transport associated with eigenvalue problems appears in the criticality calculations of nuclear reactors and can be treated as a diffusion process. This paper presents a new method to solve eigenvalue problems of neutron diffusion in slab geometry and one energy group. This formula…
We prepared novel cerium meso-tetrathienylporphyrin double-decker complexes with 2-thienyl and 3-thienyl substituents. The X-ray structures show that the porphyrin rings are distorted in a half-pipe fashion, which seems to be a common type of distortion for double-decker complexes of tetraarylporphyrins. The side-arm…
Abstract In the isopropylation of naphthalene for the production of 2,6‐naphthalenedicarboxylate, the monomer of polyethylene naphthalate plastic, a shape‐selective mordenite (MOR) zeolite catalyst provides the best selectivity for the desired 2,6‐diisopropylnaphthalene. However, the small pore size of the zeolite lim…
Cadmium sulphide thin film is deposited on the glass slide using aqueous solution of cadmium chloride and thiourea by using spray pyrolysis deposition technique at temperature of 4000C. Structural, optical and electrical properties of deposited CdS thin film are investigated. Optical studied of CdS thin film is charac…

Novel calamitic liquid crystals having an electron-deficient isoquino[8,7-h]isoquinoline moiety as a core, 2,8-didecylisoquino[8,7-h]isoquinoline (10-IQIQ-10) and 2,8-didodecylisoquino[8,7-h]isoquinoline (12-IQIQ-12), were prepared, and their phase transition behaviors, HOMO and LUMO levels, and charge carrier transpo…
Different metallic materials have different polarization characteristics as dictated by the open circuit potential, breakdown potential, and passivation potential of the material. The detection of these electrochemical parameters identifies the corrosion factors of a material. A reliable and well-functioning corrosion…
