Bubble detachment from circular cavities and flat surfaces

We determine the maximum stable volume of bubbles attached to flat surfaces as a function of the contact radius, contact angle, and capillary length. Using a shooting method to solve...

Selection of semiconducting metal oxides for light-activated gas sensors at low temperature

Abstract Light activation is a promising approach for lowering the power consumption and increasing the selectivity of chemoresistive gas sensors based on semiconducting metal oxides. In this study, different aspects of commonly used materials are investigated, compared, and eval...
