Wavelength-controlled dynamic processes are mostly based on light-triggered isomerization or the cleavage/formation of molecular connections. Control over metathesis reactions by different light wavelengths, which would be useful in controllable chemistry, has rarely been studied. Taking advantage bond energies disulfide and diselenide bonds, we have developed a wavelength-driven exchange reaction between disulfides diselenides, underwent under UV to produce Se-S bonds. When irradiated with...
In this paper, the MoS2/RGO hybrids were successfully prepared via a one-pot hydrothermal. The was used for sonocatalytic degradation of methylene blue (MB) first time. It exhibited high performance under ultrasound (US) irradiation than that pure MoS2. Then are well analyzed by various spectroscopic techniques such as TGA, X-Ray Diffraction, XPS, TEM, Raman, PL, UV–Vis and DRS etc. Furthermore, sonocatalytic-degradation mechanism is discussed. enhanced composites can be put down to...
Abstract Design and preparation structure/function integrated polymer composites with high thermal conductivities ideal mechanical properties have attracted widespread attention. Nanoscale graphene were employed to fabricate the thermal‐structural integration graphene/carbon fiber/copoly (phthalazinone ether sulfone ketone) via solution prepreg followed by hot‐compression method. The conductivity ( λ ) all improved formation of thermally conductive self‐reinforced network. was increased...

Abstract Anyang, the last capital of Chinese Shang dynasty, became one largest metal consumers in Eurasia during second millennium BCE. However, it remains unclear how Anyang people managed to sustain such a large supply metal. By considering chemical analysis bronze objects within archaeological contexts, this paper shows that casting and circulation at was effectively governed by social hierarchy. Objects belonging high elites as Fuhao, particularly ritual vessels, were made carefully...
For the three-dimensional (3D) point cloud acquisition system, accurately estimating measurement model parameters is essential, so a calibration algorithm based on kernel mean <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</i> -power error (KMPE) cost function for 3D system proposed. Firstly, space sphere with unknown radius chosen as target. Secondly, since KMPE insensitive to noise and outliers, we establish function-based nonlinear...
Aiming at the complexity of interior and variety exterior structure stock price system, this paper analyzes principles prediction based on BP neural network, provides model for market by utilizing three-layered feed forward networks, presents topology determining number hidden layers, selection pretreatment sample data determination preliminary parameters. In order to avoid local extremum promote convergence speed, Levenberg-Marquardt algorithm has been adopted. Simulation experiment...
In recent years, the rapid development of information technology has affected way world economy operates. The emergence e-commerce greatly shortened time and space distance between economic participants maximized sharing resources. However, financial management risk assessment capabilities existing supply are insufficient to adapt rapidly developing new environment. This article uses a combination normative analysis empirical analyze status quo chain small medium companies. First, this...
Ancient China is one of the most important regions for development agriculture in human history, contributing two key crops millet and rice. Meanwhile, it was closely connected to wider Eurasian network, receiving wheat barley from West. Because large isotopic differences between C 3 4 crops, we are able track their changing importance different underlying connections cultural environmental contexts. We take a ‘big data’ approach, assembling stable measurements on over 2000 ancient bones....
Both non-metallic g-C3N4 and BiVO4 are novel photocatalysts responsive to visible light, but their low charge separation efficiency restricts inconspicuous photocatalytic activity. In this paper, direct Z-type g-C3N4/BiVO4 photocatalyst was constructed by calcination hydrothermal for the degradation of methylene blue. The existence heterojunction confirmed detailed study its chemical structure morphology various characterization methods, such as X-ray diffraction (XRD), Scanning electron...
This study explores the factors that reduce impact of negative on investors' Behavioral Intentions (BIs) to use Electronic Stock Trading (EST) in Pakistan. It investigates awareness-knowledge and perceived trust EST adoption. Using a questionnaire-based survey, data were collected from 347 experienced investors, analyzed through structural equation modeling. The results indicate awareness-knowledge, trust, risk dimensions (including time, financial, performance, social, privacy, opportunity...
Abstract The use of lead, some which is characterized by a highly radiogenic signature, sharply distinguishes Bronze Age China from the rest Eurasia. Scholars have long hypothesized that silver can offer an independent proxy to characterize lead minerals. summary distribution associated with Shang and Western Zhou bronzes in this paper reveals important difference between south (Sanxingdui, Hanzhong, Jinsha, Panlongcheng, Xin'gan) Central Plains. Correlating content as well isotopic...
Online stock trading (OST) is a growing phenomenon across countries, yet there sparse literature focusing on the negative utilities (risks) that causing low adoption. Drawing from perceived risk theory, this article attempts to fill gap by identifying influential factors impede acceptance of OST in developing country, Pakistan. The study also applies Hofstede cultural theory ascertain effects moderators investors' usage behavior (UB). Based structured questionnaire, 443 valid responses were...
