Despite phenomenal rise in the efficiency of hybrid halide perovskite, RPbX3 (R=organic group, X=Cl, Br, I) based solar cells from 3% to 22% in a time span of few years, the toxicity of lead (Pb) is one of the greatest challenges for their commercialization. This propelled the search for Pb-free materials with similar…
Self-similar approximation theory is shown to be a powerful tool for describing phase transitions in quantum field theory. Self-similar approximants present the extrapolation of asymptotic series in powers of small variables to the arbitrary values of the latter, including the variables tending to infinity. The approa…
A new coordination polymer {[Cu(dps) 2 (DMSO) 2 ](ClO 4 )2} n has been synthesized basing on 4,4′- dipyridyl sulfide. The structure of the obtained complex has been studied by single-crystal X-ray diffraction analysis.
A model of minimum size clusters in orthophosphates has been suggested. In the case of monazite, the cluster includes a cerium(III) cation with nine oxygen atoms of the first coordination sphere, from seven neighboring phosphate anions. Its charge consists of the cation charge Q M and the charges of the oxygen atoms Q…
Welcome to this CrystEngComm themed issue entitled “The solid state of pharmaceuticals.”
High Zn-containing aluminum (Al) alloy AA7034 was prepared by spray forming rapid solidification technique, and studied for microstructural development and mechanical properties during subsequent hot extrusion and heat treatment processing. It is found out that microstructure after spray forming is composed of equiaxe…
Offshore installations activities entail the hazard of explosion accidents with potentially severe consequences to safety of workers, integrity of system, pollution of the environment, and economic losses. Blast walls are generally used for the purpose of reducing the explosion consequences. This study introduce a new…
本文综合利用Na+，K+，Mg2+//Cl-，SO42--H2O五元体系干基图、水图、钠图，研究柴达木盆地一里坪盐湖硫酸盐型卤水水化学特征受外来淡水补给掺杂、选择性溶解、年温差等多因素影响产生的季节性变化，其中温度为主要因素.当卤水温度降低至0℃，开始析出芒硝，水化学变质系数MgSO4/MgCl2比值急剧下降，水化学特征由硫酸镁亚型向氯化物型转化过渡.通过20~25℃晶间卤水L10和L20蒸发实验研究，确定了一里坪卤水蒸发路线、液固相组成、物相鉴定、水化学特征系数、离子行为等变化及成盐特征，并与25℃ Na+，K+，Mg2+//Cl-，SO42--H2O五元体系介稳相图理论预测计算综合对比，二者吻合性比较好，整体相对误差能控制在5…
Carburization is a thermo-chemical treatment generally employed to enhance the surface (wear) properties of low carbon steels. The recent carburization studies also focus considerable positive impact on bulk properties like tensile strength and toughness. In view of these observations, the present study focuses on mec…
A Co( ii ) framework containing a 7-c Co dimer forms a (3,7)-c binodal net incorporating redox-active triarylamine and light-active azobenzene moieties.
The purpose of this study was to develop a searchable system to confirm magnetic resonance (MR) safety information of implantable medical devices (IMDs) to safely perform magnetic resonance imaging examinations. We labeled MR safety information for IMDs based on package insert descriptions and then categorized allowed…
This research deals with a method and procedure for enhancing the structural life of the commonly used steel structure in oil and gas industries HSLA S460G2+M with a thickness of 10 mm. The type of joint and welding process is T-joint with transverse and longitudinal attachment welded using semi-automated GMAW. Filler…
The first detailed analysis of FLIM applications for Mg cell imaging is presented. We employed the Mg-sensitive fluorescent dye named DCHQ5, a derivative of diaza-18-crown-6 ethers appended with two 8-hydroxyquinoline groups, to perform fluorescence lifetime imaging in control and Mg deprived SaOS-2 live cells, which…
12 M KOH fuel is analyzed using flow injection, a Teflon spray chamber, a OneNeb nebuliser and a torch with ceramic injector.
A cone phase appears as the ground state of uniaxial magnets with comparable second-order and fourth-order anisotropy constants. In such systems, specific vortex states can exist. The authors have studied magnetization oscillations in small cylindrical particles in a cone vortex state. The study has determined the fre…
A self-assembled organic nanotube was found to promote the allylation of ketones in the aqueous phase.
A simple method for pyridoxal structural modification via furan ring closure was developed resulting in 2-acyl- and 2-heteroarylfuro[2,3- c ]pyridines. The reaction products can be proposed as pyridoxal mimetics to inhibit pyridoxal 5′-phosphate-dependent enzymes.
The solution properties of a synthesized imidazolium-based amphiphilic polyelectrolyte dissolved in pure- and mixed-solvent media composed of two aprotic polar solvents (N,N-dimethylacetamide (DMAc) and N-methyl-2-pyrrolidone (NMP)) having a similar dielectric constant are explored in the semidilute regime (1-4 wt%).…
