In this article, a clean method for the synthesis of PtPd/reduced graphene oxide (RGO) catalysts with different Pt/Pd ratios is reported in which no additional components such as external energy (e.g., high temperature or pressure), surfactants, stabilizing agents are required. The obtained were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution (HRTEM), Raman spectroscopy, photoelectron spectroscopy (XPS), induced coupled plasma atomic emission...
Pd–PEDOT/graphene nanocomposites with hierarchical structure and superior electrocatalytic performance toward ethanol oxidation are fabricated by a facile one-pot method.
Recently, more and users enterprises have entrusted data storage platform construction to proxy cloud service provider (PCSP) through technology. Under this background, the attribute-based encryption (ABE) mechanism is an alternative fill drawbacks of traditional flexible fine-grained access policy collusion prevention. However, there exist some security issues when file need be updated in practical applications. And ABE has problems excessive computation costs. In article, efficient...
Vehicular ad hoc networks (VANETs) are the communication foundation for future intelligent transportation systems and guarantee safe driving of networked vehicles. Moreover, VANETs face a series security challenges related to protection vehicle privacy, authenticity transmitted information, bandwidth limitations. To resolve these contradictions, many certificateless aggregate signature (CLAS) schemes have been proposed. However, majority them can neither resist malicious-but-passive key...
Abstract This study uses complex network analysis to investigate global stock market co-movement during the black swan event of Coronavirus Disease 2019 (COVID-19) pandemic. We propose a novel method for calculating price index correlations based on open-high-low-close (OHLC) data. More intraday information can be utilized compared with widely used return-based method. Hypothesis testing was select edges incorporated in avoid rigid setting artificial threshold. The topologies constructed...
Abstract Past accounting research contains an extensive range of disclosure and determinants studies. But these studies have one major methodological drawback: the analysis is often restricted to determination index, that is, sum disclosed items, weighted or unweighted. The profile (which reflects structure published information) generally not part design. objective this paper introduce a divisive (descendant) clustering method, which splits sample into homogeneous sub-groups corresponding...
The changing population age structure has a significant influence on the economy, society, and numerous other aspects of country. This paper innovatively applied method compositional data forecasting for prediction changes young (aged 0–14), middle-aged 15–64), elderly older than 65) in China, India, Vietnam by 2030 based from 1960 to 2016. To select best-suited model, an array transformation approaches models have been extensively employed, large number comparisons made between...
A facile and cost-effective approach has been developed towards electrochemical fabrication of a reduced graphene oxide (RGO) modified glassy carbon electrode (RGO/GCE). Scanning electron microscopy (SEM) images show that RGO is covered completely on the surface electrodes. The RGO/GCE used to detect dopamine (DA), uric acid (UA) ascorbic (AA) simultaneously via cyclic voltammetry (CV) differential pulse (DPV) methods. Compared with bare GCE, exhibits much high electrocatalytic activities...
