Covalent Organic Frameworks as Exceptional Hydrogen Storage Materials
We report the H_2 uptake properties of six covalent organic frameworks (COFs) from first-principles-based grand canonical Monte-Carlo simulations. The predicted H_2 adsorption... -
Enantioselective Oxidation of Thioanisole to Metyl Phenyl Sulfoxide by Chiral...
Chiral sulfoxides are used in asymmetric synthesis and are present in various biologically active compounds. Asymmetric synthesis of the sulfoxides has been performed by chiral... -
How to Design Linear Allenic-Type Trisilaallenes and Trigermaallenes
A theoretical prescription as to how to design allenic-type linear trisilaallenes and trigermaallenes is provided. Until now, all of the heavier group − 14 analogues of allene... -
Ergothioneine production with Aspergillus oryzae
To establish a reliable and practical ergothioneine (ERG) supply, we employed fermentative ERG production using Aspergillus oryzae, a fungus used for food production. We... -
