Advanced Materials Interfaces, EarlyView.This study introduces an approach for creating liquid‐like slippery surfaces (LLS) on various substrates. An epoxy‐silicon (EpSi) coating is applied, plasma‐activated, and immersed in an organosilane solution, forming siloxane chains. The resulting LLS exhibits ultra‐low ice adhesion, high transparency, self‐cleaning, and anti‐staining properties ...

Pneumatic Pressure Control Using on‐off Valves with Pulse Width Modulation
Chemical Engineering &Technology, Volume 46, Issue 1, Page 21-28, January 2023., 2023 To reduce hysteresis and improve accuracy of a two‐stage airplane flow valve, an on‐off switching valve with its pulse width modulation (PWM) control is proposed as a first stage in replacement of a currently used servomotor‐controlled valve. A method is introduced for properly choosing the on‐off valve and tuning the PWM parameters.
