Achieving volatile potassium promoted ammonia synthesis via mechanochemistry
Nature Communications, 2023 Potassium oxide (K2O) is used as a promotor in industrial ammonia synthesis, although metallic potassium (K) is better in theory. The reason K2O is used is because metallic K, which volatilizes around 400 °C, separates from the catalyst in the harsh ...

Thin-Film Polyimide Membrane Actuators Fabricated by Etching a Substrate by DRIE (Bosch Process)
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 This paper deals with thin-film polyimide membrane actuators. The membranes were fabricated by deep-RIE using the Bosch process for etching a silicon substrate up to the polyamide layer, since we found that the polyimide layer was scarcely etched in this

Handling Characteristics of Mems-Tweezers with Contact Surface Fabricated by Deep-Rie
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Methods for enhancing the gripping ability of microtweezers are examined in terms of friction force. Two aspects are investigated experimentally. One is a method for increasing the coefficient of friction of the handling part of the microtweezers.
