Dynamic covalent bond-based materials: From construction to biomedical applications
Supramolecular MaterialsDynamic covalent bonds (DCBs) have received significant interest due to their unique reversibility and stimuli-responsiveness. The introduction of DCBs provides materials with self-healing and controllable load and release properties, which result in the

Relaxation dynamics in covalently bonded organic monolayers on silicon [PDF]
Physical Review B, 2010 We study the dynamic electrical response of a silicon-molecular monolayer-metal junctions and we observe two contributions in the admittance spectroscopy data. These contributions are related to dipolar relaxation and molecular organization in the monolayer in one hand, and the presence of defects at the silicon/molecule interface in the other hand. We

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Dynamic geometric constraints govern covalent feasibility in KRAS G12C ligands
Discover MoleculesCovalent inhibition has emerged as an effective strategy for targeting oncogenic proteins, yet successful covalent engagement depends not only on binding affinity but also on the dynamic preservation of productive electrophile–thiol geometry.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

A molecular dynamics study of bond exchange reactions in covalent adaptable networks
, 2015 Covalent adaptable networks are polymers that can alter the arrangement of network connections by bond exchange reactions where an active unit attaches to an existing bond then kicks off its pre-existing peer to form a new bond.
