Quinaldine and Indole based pH Sensitive Colorimetric Chemosensor and their application of nanofiber

Bae J.S., Kim S-H, Son D.H. Lee Y-A., Kyungpook National University, KR

Colorimetric chemosensors are now considered as one of the most effective analytical method used in the environment monitoring. Colorimetric chemosensors for pH sensing can easily detect the primary danger or change of the surrounding environment [...]

Photocatalytic Performance of Ag modified and doped TiO2 nanoparticles

Cho C-P, Chang L.-H., National Chi-Nan University, TW

In this work, TBOT was used as the titanium source for preparation of TiO2 nanoparticles, followed by calcination at 500°C for 2 hours to achieve fine TiO2 nanoparticles powder (S1). The obtained S1 powder was [...]

Electrospinning of decorated nanofibers with active cerium oxide nanoparticles

Shehata N., Hassounah I., Meehan K., Camelio J., Virginia Tech, US

Cerium oxide nanoparticles (ceria NPs) attract a great research and commercial interests due to its observable capability to capture radicals and dissolved oxygen molecules. Keeping ceria NPs in active form; containing Ce+3 ions with O-vacancies, [...]

Recovery of phosphate from surface waters using a calcium silicate composite material for potential application in environmental remediation

Cairns M.J., Krauss C., Johnston J.H., Victoria University of Wellington, NZ

In many locations, contamination of surface waters by phosphate due to agricultural run-off is becoming a major environmental concern. Currently, there are no effective means for its removal, due to the low phosphate concentration (< [...]
