Spontaneous Non‐Catalyzed Molecular Reactions and Interactions in the Human Body: Biomedical Implications

open access: yesAdvanced Science, EarlyView.
ABSTRACT The human body functions as a natural reactor for a vast network of chemical and biological reactions and physical interactions among small molecules, proteins, cells, and numerous other components. These reactions/interactions are essential for maintaining normal physiological functions.

Theoretical study of Schiff bases and ıts pharmaceutical activity: Review

open access: yes, 2022
A Schiff bases is a nitrogeneous analogue of an aldehydes or may be ketones whose (CO) carbonyl groups has been replace by an imines group or azomethine group. It is sometimes referred to as an imines or an azomethines group.

Atomic Interlayer Mo–N4 Sites Enable Rapid Charge Transfer and Efficient CO2 Photoreduction

open access: yesAdvanced Science, EarlyView.
This work achieved efficient CO2 activation and ultrafast interlayer electron transport in a 2D COF by constructing atomic‐level Mo‐N4‐induced interlayer electron bridges (IEB), thereby kinetically and thermodynamically co‐driving the photocatalytic coupling of CO2 reduction with 4‐methoxybenzyl alcohol oxidation.
