HYDROLYTIC STABILITY OF ADAMANTANE HYBRID MOLECULES

open access: yesJournal of Chemical Technology and Metallurgy
Herein, the hydrolytic stability of new hybrid adamantane molecules modified with amino acid cysteine (Cys) at different pH is reported. Cys is a rare proteinogenic amino acid but it is a key structural unit in proteins. Cys is the only amino acid containing thiol group in the lateral chain which make it important source of sulphur for human organism ...

Coupled Chemical and Mechanical Control of the Pore Size in Carbon Honeycomb Membranes for Water Desalination

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT The advancement of 3D carbon nanostructures for next‐generation desalination membranes is hindered by limited control of the pore size to ensure effective salt rejection. Chemical functionalization and mechanical modification are known approaches to address the problem, while the combined effect of the two approaches remains unexplored.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Cross Linking and Degradation Mechanisms in Model Sealant Candidates [PDF]

open access: yes
Model compounds were investigated as to which type of heterocyclic ring is the most advantageous for curing sealants based on perfluoroalkylether chains. The relative thermal, thermal oxidative, hydrolytic, and fuel stability of potential crosslinks were
