Association between anticoagulation strategy and quality of life in chronic hemodialysis patients

open access: yesScientific Reports, 2023
Prevention of clotting in hemodialysis (HD) is a concern, but tools to monitor anticoagulation strategies as well as data on bleeding and its impact on quality of life (QoL) are scant.

A-site cation influence on the conduction band of lead bromide perovskites

open access: yesNature Communications, 2022
The A-cation influence on the mechanism of slow hot carrier cooling in perovskites is controversial. Here, Man et al. resolve a debated issue regarding A-cation influence on the electronic structure of lead halide perovskites.
