Ultrasensitive mercury sensors based on graphene decorated with nanoparticles

Ayesh A.I., Qatar University, QA

In this work we present a highly sensitive and selective sensor for detection of mercury traces in water. The sensor is constructed by creating interdigitated metal electrodes on a graphene layer placed on SiO2/Si substrate. [...]

Catalytic oxidation of carbon using TiO2 based nanoparticles prepared using flame synthesis

Memon N.K., Ismail M.A., Anjum D.H., Chung S.H., Qatar Environment and Energy Research Institute, QA

Titanium dioxide (TiO2) nanoparticles are used in numerous applications involving catalysis, photo-catalysis, water purification, electrode for Li-ion batteries, polymer fillers, and pigments. Multiple-diffusion flames are used to coat/dope the TiO2 nanoparticles with various elements such [...]
