Facile Protocol for Water-Tolerant “Frustrated Lewis Pair”-Catalyzed Hydrogenation [PDF]

, 2015
Despite rapid advances in the field of metal-free, “frustrated Lewis pair” (FLP)-catalyzed hydrogenation, the need for strictly anhydrous reaction conditions has hampered wide-scale uptake of this methodology.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Review on Degradation Technology of Polymeric Proanthocyanidin

Shipin gongye ke-ji, 2022
Proanthocyanidins are a kind of flavane-3-alcohols which exist widely in nature. Because most of the proanthocyanidins obtained from nature are high polymer proanthocyanidins with benzene ring or long carbon chain, their physiological activity is weak ...

Uptake of Hydrogen Bonding Molecules by Benzene Nanoparticles

The Journal of Physical Chemistry Letters, 2022
The uptake of molecules on nanometer-size clusters of polyaromatic hydrocarbons (PAHs) is important for the condensation of water on PAH aerosols in the atmosphere and for ice mantle growth on nanoparticles in the interstellar medium. We generate benzene clusters BzN of mean size N̅ ≈ 300 (radius R̅ ≈ 2.2 Å) as a model system for the PAH nanoparticles.
