Ab initio molecular orbital calculations on the water-carbon dioxide system. Reaction pathway for H2O + CO2 → H2CO3 The reaction pathway for H2O + CO2 → H2CO3 has been calculated using ab initio methods. The energy barrier was found to be 234 kJ/mol in the Hartree-Fock approximation wit...
had a new approach utilizing sodium pyrosulfite and potassium permanganate as the raw materials by technology of water/oil microemulsion for the fabrication of nanometer MnO2 spheres. Particles of MnO2 doped with 4 wt% Cr2O3 could retain over 150 mA h g-1, which is also round 84%...
The effect of lithium chloride (LiCl) salt on vapor-liquid equilibrium (VLE) of the binary ethanol-water system has been experimentally investigated at atmospheric pressure using modified Othmer equilibrium still. An effect of salt content in the range of 0 to 10 wt % has been investigated. ...
Electrolytes were prepared in an Ar glovebox with O2 concentration less than 0.2 ppm and H2O concentration less than 0.01 ppm. All electrolyte materials were used as received after molecular sieving to remove trace amounts of water. LiTFSI (Solvay) was used as the salt DME (Sigma-Aldr...
The catalyst and carbon precursors are ferrocene and 1,2-dichlorobenzene, respectively. Before depositing TiN, the CNT sponge was treated with nitric acid (70% of mass ratio) at 120 °C for 12 h, which was then washed with deionized water until neutral (pH ~7). After being freeze-...
This compound is sparingly soluble in water. Lithium phosphate is considered to be non-toxic and safe for general use. However, it is always recommended to handle chemicals with caution and follow proper safety protocols when working with them. Applicable Fields Batteries: Lithium phosphate is ...

The differential enthalpies of dilution of the LiBr + 1,3-propanediol + water [LiBr/HO(CH2)3OH mass ratio = 3.5:1] and LiBr + LiI + LiCl + LiNO3 + water (mole ratio = 5:1:1:0.5) systems were determined at the four temperatures of 293.15, 303.15, 313.15, and 323.15 K and in...
(up to 22.4‰) during winter dry conditions, when river water discharge (Qw) is fed by baseflow (minimumQwof 1.5 m3/s), corresponding to slow flow and thus a long water-rock contact time. In contrast, at the onset of the summer monsoon, with a sharp increase inQw(up to 221 ...
To fight fire, use dry chemical, sand, graphite; avoid use of water or carbon tetrachloride. When heated to decomposition it emits very toxic fumes of Li2O and NOx. Used as a strong reducing agent in organic synthesis and a solid electrolyte in lithium batteries. See also LITHIUM COMPOUNDS ...
