Atmospheric Doping of Stretchable Polymer Semiconductors for Skin Electronics
An atmospheric doping system using oxygen molecules in air as dopants is introduced for stretchable polymer semiconductors. The chemisorbed oxygen molecules act as acceptor, lead to increase not only the hole concentration of the semiconductor film over two orders of magnitude (3.37 × 1017 cm−3) but also electrical properties of the field‐effect ...

Effects of Water-Vapor Propellant on Electrodeless Thruster Performance
The performance of an electrodeless thruster operating on water-vapor propellant is evaluated and compared to noble-gas propellants. Cross-section data for electron interactions in water vapor are employed to predict the ionization cost as a function of ...

On the combustion mechanisms of ZrH2 in double-base propellant.
Metal hydrides are regarded as a series of promising hydrogen-supplying fuel for solid rocket propellants. Their effects on the energetic and combustion performances of propellants are closely related to their reaction mechanisms.

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

A Universal Way to Manipulate Droplet via Light‐Fueled Thermocapillary Convection
A non‐contact light‐induced droplet manipulation strategy fueled by mid‐infrared (MIR) light irradiation is introduced. No additional additives and/or complex substrate are required. Here, thermocapillary convection, directly generated by temperature gradient at outer surface of droplet via localized surface heating, plays a key role to propel the ...
