Environmental Gas Sensing with Cavitands
Chemistry – A European Journal, 2017AbstractEnvironmental gas sensing needs stringent sensor requirements in terms of sensitivity, selectivity and ruggedness. One of the major issues to be addressed is combining in a single device the conflicting requirements of molecular‐level selectivity and low‐ppb sensitivity.

Optical Fiber Communication Conference (OFC) 2019, 2019
We present a photonic chip sensor platform for near-infrared laser absorption spectroscopy, which incorporates an uncooled III-V laser and detector, on-chip methane reference cell, and 30cm-long evanescent field waveguides, integrated on a silicon photonics substrate.

Abstract Solid-electrolyte sensors for detecting air pollutants are urgently needed for the sake of environmental protection. Rapid progress is being marked in the development of sensors for CO 2 , NO 2 , NO, SO 2 , ozone and fluorocarbons. Some of them, such as the CO 2 sensor, have almost reached a stage of practical application, while others are ...
