Purpose The relationship between online reviews and purchase intention has been studied in previous research. However, there was little knowledge about the effect of information quality social presence on based stimulus-organism-response ( S - O R ) framework. purpose this study is to explore intrinsic stimulus (perceived presence) generated from response (purchase intention). Design/methodology/approach This developed a research model by applying framework test proposed hypotheses. A...

The enhanced properties of dendrimer-encapsulated gold nanoparticles were attributed to the single zwitterionic layer on new dendrimer template.

Purpose Online reviews presented in the format of multimedia information, such as pictures and videos, continue to emerge, but whether richness information can enforce quality online has remained uncertain. The purpose this paper is examine differences perceived reviews, based on theory, emotional polarity product type. Design/methodology/approach This a Web-based experiment which 12 groups constructed at different levels these three factors were designed for obtaining data. Findings study...

Zwitterionic materials have been employed to achieve excellent biocompatibility and the well-suppressed nonspecific protein adsorption of nanoparticles. However, a thick compact zwitterionic layer may prevent modified nanoparticles from entering tumor cells, resulting in low cellular internalization efficiency. To address this problem, new biocompatible micelles (PPIMYC) with thin were designed prepared. generation 2 polypropyleneimine dendrimers (G2 PPI) serve as hydrophilic external shell,...

High frequency biphasic (HFB) electrical currents are widely used in nerve blocking studies. Their safety margins largely remain unknown and need to be investigated.This study, exploring the post stimulus effects of HFB on a nerve's conductibility, was performed bullfrog sciatic nerves. Both compound action potentials (CAPs) differential CAPs (DCAPs, i.e. control subtracted by following currents) were obtained, N1 N2 components, which first second upward components DCAPs, for analyses...

The degree of accuracy in predicting the photovoltaic power generation plays an important role appropriate allocations and economic operations plants based on generating capacity data gathered from geographically separated through network. In this paper, a forecasting model is designed with optimization algorithm which developed combination PSO (Particle Swarm Optimization) BP (Back Propagation) neural proposed further validated experiment results show that predication assures prediction...

Graphene oxide (GO) was successfully prepared from the graphitization carbon based upon biomass material using fir powder as a precursor, which named FPGO. As comparison to verify successful synthesis of FPGO, GO expanded graphite (named EGO) prepared. FPGO had typical characteristics GO, possessing grossly close nanostructures and comparable element constitutions with EGO. The interlayer spacing 8.5 Å, 9.1 Å Fourier transform infrared spectroscopy X-ray photoelectron analyses indicated five...

Graphene oxide nanosheets (GONs)/carboxymethyl chitosan (CMC)/Fe3O4 magnetic composite microspheres (MCMs) were prepared by enclosing Fe3O4 particles with CMC and GONs in turn. The microstructures of GONs/CMC/Fe3O4 MCMs characterized FTIR, XRD, TEM, SEM. effects GON content, pH value, adsorption time on the capacity investigated. results show that have a greater specific surface area strong for dye wastewater. Meanwhile, mechanism was investigated, accorded pseudo-second-order kinetic model...

Comprehensive Summary The nanoelectrode‐based electrochemical method has been widely used for single‐cell analysis because of the advantages high spatiotemporal resolution and in‐situ detection capability. As an evolutional generation analysis, photoelectrochemical (PEC) sensors not only inherit above‐mentioned merits, but also possess a lower background higher sensitivity, they can operate under unbiased conditions. Moreover, electrodes are often impaired by nonspecific binding in complex...

Abstract An ethanol–water (CH3CH2OH–H2O) system was designed to synthesize α-Bi2O3 microrods by a mild and one-step solvothermal method in the presence of surfactant dodecylamine (C12H27N). X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission (TEM), diffuse reflectance spectroscopy (DRS) were employed characterize structure morphology samples. The photocatalytic activity evaluated degradation Methyl Orange (MO) under visible-light irradiation (λ > 420...

The application of ultrasmall gold nanoparticles as enzyme mimics has been drawing great attention. Herein, we developed zwitterionic dendrimer encapsulated (Au-G5MC NPs) for highly sensitive and simple colorimetric detection glucose. Au-G5MC NPs showed peroxidase-like property, which could efficiently catalyze oxidation 3,3',5,5'-tetramethylbenzidine (TMB) in the presence H2O2, producing a blue color product (oxTMB). This reaction follows typical Michaelis-Menten kinetics. Km towards TMB...

By a controllable and stepwise strategy, we have efficiently synthesized 3,4-perylenedicarboxylic monoanhydride (PDCMA), an important pigment versatile building block, in gram-scale preparation. The mild reaction conditions, high yields, simple postprocessing of the routes make it suitable for lab preparation industrial production, which successfully achieves challenge to avoid harsh low difficult purification. Furthermore, using PDCMA brominated as starting materials, also many perylene...

Effects of high frequency (HF) electrical stimulation on bullfrog's sciatic nerve were evaluated by analyzing the changes maximum conducting velocities and amplitudes compound action potentials (CAPs) recorded after a period (5s or 60s) HF (5 kHz) stimulation, during which nerve's conduction blocked. The results showed that both velocity amplitude CAPs decreased significantly when induced potential was crossing position where current had been delivered. influenced tended to recover their...

Arsenic is a toxic substance.The adsorption by activated carbon generally considered to be one of the most efficient methods remove As(V).In this paper, three kinds commercial carbons (N1, N2 and N3) were used adsorb As(V) from water.The result showed that capacity on N1, N3 2.539 mg / g, 1.014 g 0.581 respectively.N1 had an advantage for arsenic.Besides, effect ferrous(Fe 2+ ) chloride(Cl -) ion arsenate N1 was investigated.Due more sites being contributed adsorptive iron, Fe promoted N1.Cl...
