Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

Advanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

A Systemic Selective Modified mRNA Delivery Platform for Preventing Chemotherapy‐Induced Cardiotoxicity

Advanced Science, EarlyView.
In Yoo and Mainkar et al., we present a minimally invasive, CM‐selective modRNA delivery system encapsulated in lipid nanoparticles for intravenous (IV) administration. This platform enables selective cardiac translation of therapeutic modRNA but suppresses expression in off‐target tissues, including tumors.
