The constant weight percentage (10 wt%) of sisal and hemp fiber is treated with a 5% NaOH solution for improving adhesive behavior and bonded with epoxy. The prepared sisal/hemp/epoxy combination is blended with 0 wt%, 3 wt%, 6 wt%, and 9 wt% silica nanoparticles, which ...
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...
The feeding experiment lasted for 40 days to explore the effects of breeding density (30, 60 and 90 individuals·m–3) on the growth, enzyme activity and mRNA expression of aspartate aminotransferase (AST), alanine aminotransfe
Given: The concentration of mass by mass of the HCl solution is 37%. The density of the solution is 1.19 g/mL. We needed to prepare 100 mL of 10...Become a member and unlock all Study Answers St...
In this method, 1 mL of each plant extract (1 mg/mL) and 4 mL of distilled water placed in a 10 mL volumetric flask. At zero time, 0.3 mL of 5% NaNO2 and 0.3 mL of 10% AlCl3·6H2O was added. After 5 min, 2 mL of 1 M NaOH was added to the mixture and then make the ...
How many mL of a 53.4 wt% NaOH solution with a density of 1.52 g/mL will you need to prepare 2.000 L of a 0.169 M NaOH solution? The density of a certain aqueous solution is 1.17g/mL, and the solution is 3.57% by mass NaOH. How m...
For a typical synthesis of support, 28 g of NaOH (Sinopharm) was dissolved in 70 mL of deionized water (10 mol/L). After that, 2 g of anatase TiO2 (Macklin, particle size = 100 nm, denoted as TiO2-Ref1) was added into the above solution with stirring for 1 h ...
Cells were then lysed with 0.1 mol/L NaOH. [125I-] radioactivity in the lysates was counted using a gamma-counter (COBRAII Auto-gamma; Perkin Elmer). [3H]-radioactivity was counted using 15 mL Ready-Safe (Beckman Coulter; United States) and a beta-counter (Tri-Carb 2800TR; Perkin ...
The NaOH (sodium hydroxide) decomposition method has developed from only low-calcium wolframite concentrate to a general technology that can process various tungsten mineral raw materials including scheelite concentrate and refractory tungsten ore. Of course, traditional methods with low efficiency and serio...
The cells were dissolved in 0.1 N NaOH for protein determination by the bicinchoninic acid (BCA) method (Pierce, Rockford, IL). Density gradient ultracentrifugation The apoA-I (20 μl/ml)-conditioned medium of the 12 wells (12 ml) was centrifuged at 1.64 × 105 g for 24 h at 4°C ...
