A Failed Encounter in Mathematics and Chemistry: The Folded Models of van ‘t Hoff and Sachse [PDF]

open access: yes, 2016
Three-dimensional material models of molecules were used throughout the 19th century, either functioning as a mere representation or opening new epistemic horizons. In this paper, two case studies are examined: the 1875 models of van ‘t Hoff and the 1890

Directing the Mobility of Guest Molecules in Nanoporous Materials by Linearly Polarized Light

open access: yesAdvanced Science, EarlyView.
The polarization of light is introduced as a further parameter to dynamically and reversibly control the properties of a photoresponsive nanoporous material. It was used to control the mobility of the guest molecules in the pores of a metal–organic framework.

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

open access: yesAdvanced Science, EarlyView.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.
