Advances in Safe, Flexible, and Stretchable Batteries for Wearable Applications
Advanced Materials Technologies, EarlyView.Unlike previous reviews centered on component‐based deformability, this work highlights safety‐driven design strategies for flexible and stretchable batteries. By integrating material‐level engineering, geometry‐controlled structures, biocompatibility, and self‐protection mechanisms, it establishes a unified framework that connects mechanical ...

An Analysis of the Combustion Behavior of Ethanol, Butanol, Iso-Octane, Gasoline, and Methane in a Direct-Injection Spark-Ignition Research Engine [PDF]
, 2012 Future automotive fuels are expected to contain significant quantities of bio-components. This poses a great challenge to the designers of novel low-CO2 internal combustion engines because biofuels have very different properties to those of most typical ...

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 ...

Spark Ignition Measurements in Jet A: part II [PDF]
, 2000 An improved system for measuring the ignition energy of liquid fuel was built to perform experiments on aviation kerosene (Jet A). Compared to a previously used system (Shepherd et al. 1998), the present vessel has a more uniform temperature which can be

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.
