Rainstorm Flood Risk Assessment in the China–Pakistan Economic Corridor Under Different Shared Socioeconomic Pathways of the 21st Century

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Global warming has intensified the atmospheric water cycle, leading to more frequent and severe extreme precipitation events, which are a major driver of rainstorm‐induced flooding. Developing regions such as the China–Pakistan economic corridor (CPEC), spanning highly heterogeneous terrain and climate zones, face elevated risk due to limited ...

Photo-Responsive Polymersomes as Drug Delivery System for Potential Medical Applications

Molecules, 2020
Due to a strong retardation effect of o-nitrobenzyl ester on polymerization, it is still a great challenge to prepare amphiphilic block copolymers for polymersomes with a o-nitrobenzyl ester-based hydrophobic block.

Dithioketal Polymers Via Radical Polymerization of γ‐Dithiobutyrolactone

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
γ‐Dithiobutyrolactone (DTBL) behaves like a ring‐retaining monomer in radical copolymerization with a series of conjugated monomers like styrene, t‐butyl acrylate and N,N‐dimethylacrylamide. The resulting copolymers contain controlled fractions of dithioketal linkages in their backbone, allowing chemical degradation.
