Equations describing the density and dynamic viscosity of 10 to 40% KOH solution at temperatures of 20–70°С are derived. The dynamic viscosity and density were studied in a newly constructed experimental setup including an SV-10 viscometer. The deviation of the predictions from the experimental...
aElectrical current density was maintained at 1 mA cm−2 and the sample electrolyte was either a 34 wt% or 25 wt% KOH solution in distilled water. 电流密度被维护了在1 mA cm−2,并且样品电解质是一种34 wt %或25 wt %酸值解答在蒸馏水。[translate]...
Gas hydrates are stable solid crystalline structures formed when light hydrocarbons in gas form are trapped in a lattice of water molecules through hydrogen bonding (Koh et al., 2011; Qasim et al., 2019b). Perilous safety issues such as fatalities and massive shutdowns might happen when these...
we performed two control samples: (1) CTS pyrolysis of the Co salt precursor without the 2-MeIm ligand (denoted as Co-CTS) and (2) furnace treatment of the MOF (i.e., Co-N-furnace). Large particles (~140 nm) and agglomerated particles were observed after pyrolyzing the Co precurs...
Real-time propagation (RTP) has become an appealing technique for the solution of the time-dependent Kohn–Sham calculations, namely, real-time time-dependent density-functional theory (RT-TDDFT), or general approximations to the time-dependent Schrödinger equation4,5,6,7,8,9. It is based ...
Current density influences the mixing of the solution and mass transfer between bulk and electrodes (Holt et al., 2005). Literature reveals a wide range of applied current density from 1 to 100 mAmp/cm2 which differs from case to case and on the type of wastewater. A logical analysis ...
Optoelectronic interconnections can provide a practical solution for the ever increasing communication bottleneck problems when combining a multitude of information processing units to perform a function. As research activities progress ... S Koh - US 被引量: 254发表: 1998年 Packing density and intercon...
Kinetic current densities IKin at 0.8 V (mA cm−2) for the oxygen reduction reaction (ORR) of mono- and bimetallic Me–N–C catalysts evaluated (a) in acid, 0.1 M HClO4 and (b) in alkaline, 0.1 M KOH before (solid) and after accelerated stress tests (AST; hatched);...
The catalytic performance of Mo2C hybrids was investigated by a three-electrode system in 0.5 M H2SO4and 1.0 M KOH solutions (see more details in Methods). As revealed in Fig.5a, H-Mo2C/NG shows the highest HER performance among all catalysts in acidic media, and only requires an...
Inverted organic solar cells with ZnO nanowalls prepared using wet chemical etching in a KOH solution. We report on the photovoltaic (PV) performances of inverted organic solar cells (IOSCs) that were fabricated from PCBM:P3HT polymer with a ZnO thin film an... KS Shin,HJ Park,B Kumar,....
