Peptide-Hypervalent Iodine Reagent Chimeras: Enabling Peptide Functionalization and Macrocyclization

Jérôme Waser, Christian Heinis, Xinjian Ji, Xingyu Liu

Herein, we report a novel strategy for the modification of peptides based on the introduction of highly reactive hypervalent iodine reagents-ethynylbenziodoxolones (EBXs)-onto peptides. These peptide-EBXs can be readily accessed, by both solution- and soli ...

Elucidating the transition between CO2 physisorption and chemisorption in 1,2,4-triazolate ionic liquids at a molecular level

Paul Joseph Dyson, Zhaofu Fei, Xuemei Yang

Capture of CO2 is a crucial process to achieve carbon neutrality. High-performance CO2 capture involves both physi- and chemi-sorption, with a transition between them. However, the underlying mechanistic insights required to produce the methods to tune the ...

Atomic-Level Structure of Zinc-Modified Cementitious Calcium Silicate Hydrate

Karen Scrivener, David Lyndon Emsley, Paul Bowen, Manuel Cordova, Pinelopi Moutzouri, Amrit Venkatesh, Ziga Casar, Anna Morales Melgares

It has recently been demonstrated that the addition of zinc can enhance the mechanical strength of tricalcium silicates (C3S) upon hydration, but the structure of the main hydration product of cement, calcium silicate hydrate (C-S-H), in zinc modified form ...
