In this work, the unit cell parameter ( a ) of the series of cubic ABX 3 perovskites was modeled using counter‐propagation artificial neural networks, and the influence of different input variables was examined by using algorithm for automatic adjustment of the relative importance of the variables. The input variables…
Iron ore tailings filled polypropylene (PP) composites were produced using the compo-indirect squeeze casting (C-ISC) process. Particle sizes 150, 212 and 300 m where considered for different volume fractions of 5% to 30% at intervals of 5%. The tensile and impact behavior of the produced composites were investigated,…
In this work, an atmospheric pressure glow discharge helium plasma treatment was employed to modify the surface properties of jute fibres. The resulting bio-composites showed an increase in flexural properties and interlaminar shear strength (ILSS) compared to composites produced using untreated jute fibres. To unders…
The influence of Al content on the evolution of microstructures and mechanical properties of Ti-xFe-yAl alloys quenched from a β field was investigated via hardness measurements, tensile tests, scanning electron microscopy (SEM) equipped with electron back scattering pattern (EBSP) analyzer, and conventional transmiss…
The inhibitor effect of 1,7− bis (2- hydroxy benzamido)-4-azaheptane H4L3 on the corrosion of mild steel in 1M hydrochloric acid (HCl) has been investigated at 308 K using weight loss measurements and electrochemical techniques (impedance spectroscopy and polarisation curves). Inhibition efficiency is dependent upon t…
The aim of this paper has been to characterize the relation between the pyrolysis temperature of phenol-formaldehyde resin, the development of a porous structure, and the mechanical properties for the application of semipermeable membranes for gas separation. No previous study has dealt with this problem in its entire…
The functions of the piston and the loads that act on it present a very special set of requirements for the piston material. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
The synthesis, X-ray structure, solution stability, and photophysical properties of Eu(III) complexes with pyrazine-2,6-dicarboxylic acid (H(2)PYZ) are reported, and compared to structurally analogous complexes with pyridine-2,6-dicarboxylic acid (H(2)DPA). The [Eu(PYZ)(3)](3-) complex demonstrates highly efficient me…

The characteristics of scatting and extinction spectra of gold nanoshell pairs, dependent on the its geometry and physical parameters, are investigated by the Finite Element Method based on the plasmon hybridization theory. The numerical results indicate that the resonante peaks in the scattering spectra and the extin…
Motivated by recent results in mathematical virology, we present novel asymmetric Z[tau]-integer-valued affine extensions of the non-crystallographic Coxeter groups H-2, H-3 and H-4 derived in a Kac-Moody-type formalism. In particular, we show that the affine reflection planes which extend the Coxeter group H-3 genera…
基于密度泛函理论中的BPBE方法和从头算的CCSD(T)方法, 充分考虑自旋多重度, 优化并得到了TiBn (n＝1～12)团簇的稳定构型. 二次差分能量分析表明n＝2, 8, 10的团簇为幻数团簇. 值得注意的是, 电子相关效应对TiBn团簇的相对能量有重要影响. 密度泛函理论方法得到n＝3, 7, 10团簇为幻数团簇. 对垂直电离势、垂直电子亲合势和化学硬度的分析表明, 除TiB8外, n为偶数的团簇有较小的电子亲合势和较大的电离势, 从反应性上来说, 更稳定一些.
The associative effect towards the corrosion of AISI 304 stainless steel caused by the main two bacterial species present in marine environments around the Canary Islands (Spain) has been investigated using electrochemical techniques. The test environments were sterile conditions, with SRB (sulphate-reducing bacteria)…
We deomonstrate the existence of optical topological transition, the optical equivalent of Lifshitz transition in electronic systems, by controlling the topology of the optical isofrequency curve using metamaterials.
Two new polyhydroxypregnane glycosides, namely cynotophyllosides G-H (1-2), were isolated from the roots of Cynanchum otophyllum, together with three known steroids. Their structures were established by spectroscopic methods and acid-catalysed hydrolysis. Cynanchum otophyllum also known as “ Qingyangshen“ in tradition…
This paper aimed to analyze the net social benefits from switching petroleum-based plastic to bioplastic based on Cost-Benefit Analysis (CBA). The status quo was no PLA production in Thailand and another case is having PLA production based on the assumption that the HDPE production was not replaced by the PLA producti…
This paper is the second part of the research work dedicated to evaluation of mechanical properties of polymer composites reinforced by knitted fabric. Three different approaches were applied for the task. Two of them: a) FEM analysis using Solid Works combined with structural modeling based on experimentally-determin…
Employing nanomaterials and nanoparticles in the industrial and research area could reduce use of certain agrochemicals such as pesticides, and further provide a better ability to control the application and dosage of active substance to the target. Here, the use of silica nanoparticles (SiNPs) as biopesticide was app…
Particles that have the potential to deliver imaging agents and drugs to cells and tissue now have many different shapes and sizes. This diversity in particle shape could provide new options for potential treatments of diseases because geometry affects biodistribution. However, the myriad of particle shapes now availa…
