Accurate sensing of ion concentrations in body fluids is importance to monitor cell functions, and any deviation the concentration serves as a warning sign pathophysiological conditions. Here, fabrication approach for an integrated device consisting two electrochemical transistors, capable selective simultaneous detection between potassium sodium ions analyte demonstrated. A common in-plane gat...

We report the first astronomical detection of the CF (fluoromethylidynium) ion, obtained by recent observations of its J = 1 − 0 (102.6 GHz), J = 2 − 1 (205.2 GHz), and J = 3− 2 (307.7 GHz) pure rotational emissions toward the Orion Bar. Our search for CF— carried out using the IRAM 30m and APEX 12m telescopes—was motivated by recent theoretical models that predict CF abundances of a few × 10−1...

Improper treatment and disposal of perchlorate can be an environmental hazard in regions where solid rocket motors are used, tested, or stored. The solubility and mobility of perchlorate lends itself to ground water contamination, and some of these sources are used for drinking water. Perchlorate in drinking water has been determined at sub-mug l(-1) levels by extraction of the ion-pair formed ...
