Proton transfers in the bacteriorhodopsin photocycle

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2006
The steps in the mechanism of proton transport in bacteriorhodopsin include examples for most kinds of proton transfer reactions that might occur in a transmembrane pump: proton transfer via a bridging water molecule, coupled protonation/deprotonation of two buried groups separated by a considerable distance, long-range proton migration over a hydrogen-

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

The curious case of proton migration under pressure in the malonic acid and 4,4′-bipyridine cocrystal

open access: yesIUCrJ
In the search for new active pharmaceutical ingredients, the precise control of the chemistry of cocrystals becomes essential. One crucial step within this chemistry is proton migration between cocrystal coformers to form a salt, usually anticipated by ...

On the intrinsic limitation of the Rosenbluth method at large momentum transfer

open access: yes, 2004
Correlations in the elastic electron proton scattering data show that the Rosenbluth method is not reliable for the extraction of the electric proton form factors at large momentum transfer, where the magnetic term dominates, due to the size and the ...

Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

open access: yesAdvanced Functional Materials, EarlyView.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

THEORETICAL STUDY OF PROTON-TRANSFER ENERGY SURFACES IN SMALL WATER CLUSTERS AND CUBIC ICE

open access: yesTASK Quarterly, 1998
The energetics of proton transfer in water clusters of size from two to six molecules and in cubic icc was analyzed in detail using both Hartree Fock and gradient-corrected density functional theory.

Revealing nucleon-nucleon correlation effects through sub-Coulomb transfer reactions in 92Mo+54Fe

open access: yesPhysics Letters B
Cross sections for neutron and proton transfer channels were measured in the proton-rich system 92Mo+54Fe using the PRISMA magnetic spectrometer. The energy dependence of the absolute transfer cross sections was investigated over a beam energy range ...
