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...
18. The working temperature for most liquid working pairs, including LiCl/H2O, LiBr/H2O, KOH/H2O, NaOH/H2O and CaCl2/H2O, are below 100 °C, which meet the requirements of SSLTHS in terms of temperature. Among them, LiCl/H2O, with the best energy storage density (1219 Wh/kg), needs...
As the solution turned transparent, a KOH solution (0.3 g/mL) was added dropwise under magnetic stirring until a clear, gel-like consistency was achieved. 4.7 Fabrication of the Symmetric/Asymmetric Supercapacitors All solid-state sFSs were fabricated by assembling two identical TMO yarns (CNO, ...
Surface treatment of the Laves-phase alloy electrode with a boiling 6 M KOH solution greatly increased the i0 value even before activation, leading to rapid activation. By sintering TiMnV0.5 alloy with nickel powder in vacuo, it was found that the i0 value increased with the content of Ni ...
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 ...
Answer to: What is the mass of a solution that has a volume of 0.100L and a density of 1.07g/ml. By signing up, you'll get thousands of...
Na2SO4, KOH and KOH/K3Fe(CN)6 redox electrolytes. The optimum energy density and power density were 1851 Whkg'1 and 68 kWkg'1 at current density of 20 Ag'1 in mixed KOH/K3Fe(CN)6 electrolyte. 展开 关键词: ELECTROPLATING SYNTHESIS of Nanocomposite materials COMPOSITE materials synthesis ...
It uses strict steam activation process, it has a high specific surface area and optimized pore size to adsorb color molecules and odor molecules in the solution.It is used for the deep purification of direct drinking water to effectively remove residual CL and ensure the ...
The reaction mixture was filtered and washed with excess of water and acetone. The residue was suspended in 25 mL of 2 % (w/v) aqueous KOH solution in RBF (100 mL) and refluxed for 15 min. Upon completion of the hydrolysis, the suspension was filtered, and dried under vacuo, to ...
To evaluate the alkaline OER electrocatalytic performance ofA-Fe2S1N5/SNC, we conducted electrochemical measurements in a 1.0 M KOH solution via a standard three-electrode configuration. The obtainedA-Fe2S1N5/SNC displayed more obvious advantages (Fig.3a...
