Water pH is a critical parameter that determines the acidity or alkalinity of water. Measured on a scale from 0 to 14, pH levels influence chemical reactions, biological processes, and overall water ...
Penn State University researchers have built a dual-gated graphene sensor that operates reliably in liquid environments, ...
Nanosensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale. They ...
