Dust ball physics and the Schwarzschild metric [PDF]
American Journal of Physics, 2017 A physics-first derivation of the Schwarzschild metric is given. Gravitation is described in terms of the effects of tidal forces (or of spacetime curvature) on the volume of a small ball of test particles (a dust ball), freely falling after all particles were at rest with respect to each other initially.

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

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery
Advanced Functional Materials, EarlyView.A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Tissue‐Adhesive Fabric‐Based Bioelectronics for Wearable and Implantable Applications
Advanced Functional Materials, EarlyView.An implantable and wearable bioelectronic textile (iTextile) is introduced as a unified platform bridging wearable and implantable systems. By integrating a self‐healing polymer, stretchable silk fabric, conductive composite electrodes, and an adhesive hydrogel, the platform enables conformal, stable interfacing with soft tissues. The iTextile supports

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.

Chemical and physical properties of interstellar dust [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractThe characteristics of interstellar dust reflect a complex interplay between stellar injection of stardust, destruction in the ISM, and regrowth in clouds. Astronomical observations and analysis of stardust isolated from meteorites have revealed a highly diverse interstellar and circumstellar grain inventory, including both amorphous materials ...
