Abstract:
In this paper, a polynuclear heterometallic compound (H3O)[Al3Ni4(OH)6(MBA-NO2)6(H2O)6] (Al3Ni4, H2MBA-NO2 = 2-hydroxy-3-methoxy-5-nitrobenzoic acid) with a seven-star disk metal core has been synthesized by the solvothermal method. Al3Ni4 has good stability in water and several organic solvents, and its solid powder shows a good photothermal effect under 980 nm laser irradiation, and the temperature can reach 138.8 °C within 100 s under 1.0 W cm-2 power irradiation. Considering its good photothermal effect, water evaporation of Al3Ni4 was measured. It can be further used as a photothermal material in seawater evaporation.

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...

Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
