Hace 1 día · To prepare cobalt-nitrogen doped carbon black (CoNCB), 100 mg OCB was dispersed into 30 mL deionized water and ultra-sonicated (Fisherbrand™ 505 Sonicator) for 30 min in the ice bath.
Hace 5 días · The gas–liquid equilibrium experimental reactor after the reaction of the absorbent + additives out, the purpose is to detect the volatilization of a certain amount of organic amines after the gas–liquid carrying the amount of fugitive, divided into two equal parts, about 100 g, into a three-mouth flask, one directly into the 40 ℃ water bath device, the other loaded with 0. 1 mol/molCO 2 ...
Hace 1 día · Equilibrium systems reveal the types of complexes that develop in response to the pH of the surrounding environment, allowing the identification of molecules with potential biological properties. This knowledge can be used to create novel chemical compounds with medical and pharmacological applications by synthesizing specific structures observed in solutions.
Hace 2 días · A cobalt-based layered MOF ([Co 2 (μ-SO 4)(Hppza) 2 (H 2 O) 3] n (SEU-1) has been successfully constructed and comprehensively characterized. The maximum specific capacitance of SEU-1 is 145.5 F g −1 at 1 A g −1 , along with the specific capacitance retention of 92.7 % at the current density of 5 A g −1 after 6000 cycles in 3 M KOH solution, suggesting SEU-1 can be applied to high ...

Hace 1 día · Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silvery metal .
Hace 4 días · Therefore, thermodynamic equilibrium equations, particle growth equations in a co-precipitation system are established, and CFD simulations are also done here. The reaction equation for the co-precipitation of nickel–cobalt–manganese ternary precursor in a crystallizer to form hydroxide precipitates is shown in Equations S1–S3 .
