On the physics of dust grains in hot gas
The Astrophysical Journal, 1979 Charging of dust grains in hot (10/sup 4/--10/sup 9/ K) plasma is studied, including photoelectron and secondary electron emission, field emission, and transmission of electrons and ions through the grain; resulting grain potentials are (for T > or approx. = 10/sup 5/ K) considerably smaller in magnitude than found by Burke and Silk.

Observation-constrained Direct Radiative Effects of Dust Aerosols
, 2022 Mineral dust aerosols play an important role in modulating the radiative energy budget of Earth-Atmosphere system on regional to global scales through their interactions with both solar and thermal infrared radiations, which is known as the direct ...

Advanced Functional Materials, EarlyView.A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for
