Simulation of a Multicomponent Trace Gas Electric Swing Adsorption

C. Geitner [1],
[1] Fraunhofer institute, Oberhausen, North Rhine-Westphalia, Germany

Introduction: Electric swing adsorption is a promising technique for energy efficient gas cleaning and adsorbate recovery. Contrary to state of the art temperature swing and pressure swing adsorption, one can control the mass flow independently of the heat flow for desorption in an ... En Savoir Plus

Tunable Flat-Plate Absorber Design for Active Sound Absorption

R. Boulandet [1], K. O. Bjornsson [1], H. Lissek [1],
[1] Ecole Polytechnique Fédérale de Lausanne, Switzerland

Noise reduction at low frequencies is a major issue in many workspaces and indoor public places. Unlike mid- and high-frequency noise, low frequency noise is less attenuated by using conventional sound absorbing materials. This communication proposes an electro-mechano-acoustic absorber ...

生命体系中,位于细胞上的各种离子通道精妙的调控着各种生理生化过程。以此为原型,各种各样的仿生纳米体系也被相继开发,其中,纳流二极管研究领域更是发展迅猛。然而,现有的关于纳流二极管的研究都是通过 pH,电压等外界刺激改变表面固定功能基团的电荷类型从而调节纳流二极管的方向,这大大限制了纳流二极管功能的调控自由度。于是,我们制造了一种通过光响应的同时可以进行 pH 调节的“即插即用”双向纳流二极管。该体系基于聚合物单纳米通道,通过化学接枝,利用光响应主客体作用原理实现“即插即用”功能。通过实验实现了实验设计,并利用理论模拟进行仿真分析。模拟过程使用 COMSOL ...
