LED-Based Photoacoustic NO2 Sensor with a Sub-ppb Detection Limit.
ACS Sensors, 2021 A high-sensitivity light-emitting diode (LED)-based photoacoustic NO2 sensor is demonstrated. Sensitive photoacoustic gas sensors based on incoherent light sources are typically limited by background noise and drifts due to a strong signal generated by ...

Plasticized PVC Membrane Modified Electrodes: Voltammetry of Highly Hydrophobic Compounds
Membranes, 2020 In the last 50 years, plasticized polyvinyl chloride (PVC) membranes have gained unique importance in chemical sensor development. Originally, these membranes separated two solutions in conventional ion-selective electrodes.

Facile synthesized carbon dots for simple and selective detection of cobalt ions in aqueous media
Cogent Engineering, 2022 A simple method was demonstrated for detecting cobalt ions based on the fluorescence quenching of carbon dots (CDots). The best quantum yield for CDots synthesized by microwaving lime and methanolamine is 49.42%. The detection range of this research is 0–

Information limits for detecting a subhypergraph [PDF]
Stat, 2021 We consider the problem of recovering a subhypergraph based on an observed adjacency tensor corresponding to a uniform hypergraph. The uniform hypergraph is assumed to contain a subset of vertices called as subhypergraph. The edges restricted to the subhypergraph are assumed to follow a different probability distribution than other edges.

A Review of Photothermal Detection Techniques for Gas Sensing Applications
Applied Sciences, 2019 Photothermal spectroscopy (PTS) is a technique used for determining the composition of liquids, solids and gases. In PTS, the sample is illuminated with a radiation source, and the thermal response of the analyte (e.g., refractive index) is analyzed to ...

Capacity limits in face detection [PDF]
Cognition, 2022 Face detection is a prerequisite for further face processing, such as extracting identity or semantic information. Those later processes appear to be subject to strict capacity limits, but the location of the bottleneck is unclear. In particular, it is not known whether the bottleneck occurs before or after face detection.
