Magnetization and specific heat measurements were carried out on Pr0.9RE0.1Ni (RE = Tb, Dy, and Ho) single crystals. Spin rearrangements were observed along the \(c\)-axis of single crystals with relatively small critical fields, \(B_{\text{c}} = 6.8\), 4.0, and 2.6 T for RE = Tb, Dy and Ho, respectively. The magnetic…

Background and purpose: People are always exposed to ionizing radiation, which could badly influence their health. The degree of these influences depends on the level of radiations. In this study the dose of indoor gamma radiation was assessed using RDS-110 Multi-purpose Survey Meter. Materials and methods: To determi…
This study is performed primarily to investigate the effect of chemical modification on carbon nanotubes surface towards biogas purification performance of mixed matrix membrane. In this study, polyethersulfone (PES)-carbon nanotubes mixed matrix hollow fiber membrane for modified and unmodified carbon nanotubese were…
Growth of lead sulphide thin films has been carried out electrochemically on indium doped tin oxide coated conducting glass substrates from an aqueous acidic bath containing Pb(CH3COO)2 and Na2S2O3. X-ray diffraction pattern showed that the deposited films possess cubic structure with most prominent reflection along (…
Background: The thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composi on. When a large enough ac vity of radioac ve iodine like I, I, I is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. In fact, as it is well known, some isot…
Thermal stability after recalescence of the single-phase supersaturated granular grains prepared in Co-15 at.%Cu immiscible alloy melt was investigated. As for undercooled Co–Cu alloy, a transition from dendritic to granular crystals occurred when ΔT ≥ ΔT∗, which was induced by an abrupt change in the dendritic growth…
The presence of edges locally breaks the inversion symmetry of heterostructures and gives rise to lateral (edge) spin-orbit coupling (SOC), which, under some conditions, can lead to the formation of helical edge states. If the edge SOC is strong enough, the helical edge states can penetrate the band gap and be energet…
This paper reports on preparation and characterizations of nanohybrid TiO2/ZnO using sol-gel spin-coating techniques. The study involved of modification band-gap energy of Titanium dioxide (TiO2) at different precursor molecular concentration of Zinc oxide (ZnO). The Field Emission Scanning Electron Microscope (FESEM)…
The crystal structure and magnetic properties of BiFeO3 samples, proton-irradiated with 0, 10, and 20 pC/μm2, were investigated with x-ray diffraction (XRD), vibrating sample magnetometer, and Mössbauer spectroscopy measurements. From the Rietveld refinement analysis of the XRD patterns, the crystal structure of BiFeO…
The reaction temperature has essential effect on quality of the product synthesized by hydrothermal method. We report here the variation of the optical characteristics of Mn-doped ZnS nanocrystallites prepared by mean of the stated method from Zn(CH$_{3}$COO)$_{2}$.2H$_{2}$O, Mn(CH$_{3}$COO)$_{2}$.4H$_{2}$O and Na$_{2…
Fe-W heterometallic complexes, in which an FeX2 (X = Cl, SPh) moiety is attached to monodithiolene oxotungsten through a sulfide bridge, that is, [Ph4P]2[Cl2Fe(S)2WOS2] (1), [Ph4P]2[Cl2Fe(S)2WOS2(DMED)] (2, DMED = dimethylethylenedicarboxylate), [Ph4P]2[Cl2Fe(S)2WO(tdt)] (3, tdt = toluenedithiolate), [Ph4P]2[(SPh)2Fe(…
We study the algebraic structure of the Dirac fermion state in the organic conductor, \alpha-(BDET-TTF)_2I_3. We find a pair of generators for the Hamiltonian of \alpha-(BDET-TTF)_2I_3 that describes the chirality of Dirac fermions. The phase parameters associated with those generators have an intimate and simple rela…
Abstract This paper is a follow-up and update of the article “Titanium and Its Alloys” in Volume 9 of the ASM Handbook, Metallography and Microstructures [1]. Because of its inherent characteristics, titanium is one of the more difficult metals to prepare for metallographic examination, as illustrated below. The chall…
A new organic-inorganic hybrid nanocomposite Zn-Al-MCPA layered double hydroxide was prepared by intercalation of 2-methyl-4-chlorophenoxy acetic acid (MCPA), into Zn-Al-layered double hydroxide (ZAL) at various concentration of MCPA ranging from 0.1 to 0.7. The pH of the formulation was kept constant at 7.5. Well-ord…
Low-temperature heat capacity of potassium germanate glasses (xK2O?(100-x)GeO2; x=0.0, 10.1, 19.0, 28.2, 39.0) (x indicates K2O mol% content) has been measured in the temperature range from 2 to 50 K with K2O content. From a result of the heat capacity Cp, it has been found that an excess heat capacity is not caused b…
Some statistical properties of origami (the art of paper folding) are investigated. In a crease pattern of an origami work, a paper sheet is divided into many “cells” surrounded by creases. We compute the cell-size distributions of four origami works and find that they are described by the superposition of lognormal d…
Four aroylhydrazine-amides receptors AR1-4 with a hydrazine spacer have been designed, synthesised and characterised as novel colorimetric chemosensors by typical spectroscopic techniques. The receptors AR1–3 exhibited certainly selectivity and sensitivity towards F− and AcO− , forming 1:1 stoichiometry complex by hyd…
A 1wt%Pt/Co3O4/CeO2-ZrO2-SnO2/r-Al2O3 catalyst was prepared to realize complete combustion of toluene at the lowest temperature possible without excessive use of platinum particles. The addition of Co3O4 to Pt/ CeO2-ZrO2-SnO2/r-Al2O3 as a promoter was effective in decreasing the amount of platinum without significant…
Background and Aims: In response to esthetic demand of patients, ceramic abutments have been developed. Despite esthetic of zirconia abutments, machining accuracy of these abutments has always been a question. Any misfit in the abutment-implant interface connection can lead to detorque and screw loosening. The aim of…
