Mesoporous Alumina Affinities for Metals as a Function of pH

Hepburn R., Fujimi Corporation, US

One important application for mesoporous alumina is as the adsorbent for retaining Molybdenum-99m in the Molybdenum/Technetium generators used for medical imaging throughout the world. In 2016, Fujimi created a novel mesoporous alumina material that could [...]

Nitrogen-doped porous carbon for the removal of Cr or As in aqueous solutions

Han J.S., Ha D.G., Han J.S., Kang S-H, Seoul National University, KR

The removal of hexavalent chromium and arsenic from aqueous solutions was investigated with nitrogen-doped porous carbon. Excellent adsorption behavior was obtained due to the strong attraction between [HCrO4]- or [H2AsO4]- and nitrogen sites under weak [...]

Carbon NanoDots for Selective Optical Cation Detection

Buiculescu R., Fouskaki M., Chaniotakis N.A., University of Crete, GR

In the present work, custom designed and synthesized carbon nanodots (C-dots) with cation selective functional organic ligands (carboxyl or amino) are used for the optical detection of cations. The ligands on the surface are able [...]

Fabrication and Testing of a Miniaturised Water Quality Monitoring pH and Conductivity Sensors

Banna M.H., Najjaran H., Sadiq R., Rodriguez M.J., Imran S.A., Hoorfar M., University of British Columbia, CA

Development of cost-effective, durable and sensitive on-line water quality monitoring sensors that can be installed across the water distribution network has attracted attentions to increase the frequency of monitoring and hence reduce the risk of [...]

Removal of Zn(II) from Aqueous Solution by Biosorption using two Green Algal Species Oscillatoria sp. & Spirogyra sp.

Singh D., National Institute of Technology, Kurukshetra, IN

Pollution due to heavy metals has become an environmental problem of worldwide concern due to their increased discharge, toxicity, non-biodegradable and persistence nature. Major anthropogenic sources of heavy metals include metal extraction, metal fabrication, metal [...]

Gold Nanorods: Synthesis and Modulation of Optical Properties

Tiwari N.R., Kalele S.A., Kulkarni S.K., University of Pune, IN

Metal nanoparticles offer a wide area of application owing to their size and shape dependent optical properties. Recently, there has been significant interest in gold nanorods due to their potential application in the field of [...]
