The present study investigates the impact of selected variables on young consumers' purchase intentions in online shopping (online intention), utilizing respondents who reside Kushtia, Bangladesh. Based a sample 220 participants, results show that convenience, relatively high pricing, time-saving, and social media have positive significant effect behavior. Conversely, product, security, personal interests adversely intentions, Demographic analysis indicates were primarily male (85%), aged...
Date palm fiber (DPF) was demonstrated in the present issue as a potential low cost adsorbent for removal of hexavalent chromium [Cr(VI)] from aqueous solution.A series batch tests were conducted and influence initial metal ion concentration, contact time, pH solution dosage investigated.The characterized by Fourier Transformed Infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) Brunauer-Emmett-Teller (BET) to confirm surface properties DPF adsorbent.The adsorption process found...
The data presented in this article are related to the research entitled "NiCoPt/Graphene-dot Nanosponge as a Highly Stable Electrocatalyst for Efficient Hydrogen Evolution Reaction Acidic Electrolyte (N.-A. Nguyen et al., 2020) [1]. This reports simple method synthesize NiCoPt/Graphene-dot an electrocatalyst with low Pt loading but high hydrogen evolution reaction (HER) performance. morphology of was analyzed by scanning electron microscopy (SEM) and high-resolution transmission (HRTEM)...
Acetophenone, a keton, was demonstrated to cause acute and delayed types of insecticidal ovicidal activities against the mosquito, Culex quinquefasciatus Say, under laboratory conditions. At 0.05-10ppm, acetophenone induced cumulative (larvicidal+pupicidal+adulticidal) mortality in concentration-activity manner. Delayed activity detected F_1 progeny showing lower fecundity significant larval mortality. Morphological aberrations were evident larvae, pupae adults, i.e., shortening,...
A three-dimensional PtMo nanosponge wrapped with ultra-thin layers of graphene dots (denoted as 3D Pt x Mo 1-x @graphene) has been developed for catalysis the hydrogen evolution reaction (HER). The graphene-dot wrapping carries out by exfoliating carbon during co-reduction and precursors at a low temperature in an aqueous solution. outstanding HER performance superb durability, both acidic alkaline electrolytes, are attributed to synergistic effects inner metallic alloy networks outer...
We report a simple method to prepare plasma-treated NiAu nanosponge as an electrocatalyst for hydrogen evolution reaction (HER) in water electrolysis. First, as-prepared sample was synthesized by using NaBH 4 reducing agent without any surfactant. Second, the treated argon plasma under atmospheric pressure with treatment time of 15 min obtain final sample. The performed HER. As result, exhibited enhanced-performance HER activity well stability because exposure more active sites and...
Developments of high and efficient electrocatalyst are significant attentions for the hydrogen evolution reaction. Platinum metal group its alloys represent most catalytic activity reaction (HER). However, cost low abundant Pt impede their commercial scale-up application. To solve these problems, transition-metal based catalysts developing to alter Pt-based catalysts. In this work, we used carbon dot (C-dot) as a structure-directing agent first synthesize NiCoOH nano-flower, then, sulfur...
In this study, we report a simple method to prepare Ni x Rh y nanosponges while using NaBH 4 as reducing agent without any surfactant for hydrogen evolution reaction in water electrolysis. The ratio of and has been changed get various electrocatalysts (Ni, 3 1 , Rh), respectively. Among the catalysts prepared, electrocatalyst exhibited high electrocatalytic activity with an overpotential 48 mV at current density -10 mA.cm -2 superior stability even after 2000 cycles CV acidic electrolyte....
This work reports a large-scale and low-cost synthesis of highly effective, durable, cheap NiCoPt/C-dot catalysts for hydrogen evolution reaction (HER). Simultaneous co-reduction the metal precursors carbon dots (C-dots) was confirmed by TEM, XPS, Raman techniques. The SEM result clearly indicates that C-dots act as structure-directing agent assisting to generate 3D nanosponge complex structure, which has an abundance electrochemically active sites. Synthesis procedure yields nanoporous...
