Ligand “Brackets” for Ga–Ga Bond
Inorganic Chemistry, 2016 The reactivity of digallane (dpp-Bian)Ga-Ga(dpp-Bian) (1) (dpp-Bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) toward acenaphthenequinone (AcQ), sulfur dioxide, and azobenzene was investigated. The reaction of 1 with AcQ in 1:1 molar ratio proceeds via two-electron reduction of AcQ to give (dpp-Bian)Ga(μ2-AcQ)Ga(dpp-Bian) (2), in which ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Ga-doped 3D ordered porous SnO2 with an ultrasmall pore size for enhanced formaldehyde sensitivity
, 2022 Pure and Ga-doped 3 D ordered porous SnO2 (3DOPS) and SnO2 nanoparticles (NPs) were prepared. The 3DOPS/3% Ga-based sensor exhibits an improved response (61/50 ppm) to formaldehyde (HCHO), and the response is 3 times higher than pure 3DOPS (21/50 ppm) at
