Herein, a label-free, sensitive, and selective fluorescence method for the detection of trace selenite (Se(IV)) in water sample by carbon dots (CDs) was reported. The fluorescence CDs probe was simply and rapidly synthesized within 4 min by microwave-assisted pyrolysis of citric acid and...

Selenium accumulation in ecosystems beyond the limit is highly toxic, thereby provoking the necessity to generate green approaches to convert the toxic selenite to non-toxic and beneficial selenium nanoparticles. Photosynthetic microalgae are emerging as smart green cell factories for...

Purpose: The purpose of this paper is to investigate the impact of Federal Open Market Committee (FOMC) meetings and the changes of the target rates on stock market uncertainty. Design/methodology/approach: Multivariate regression analysis is applied to the historical data of VIX, FOMC meetings...

There is an increasing need to establish wastewater treatment facilities for improving water quality of heavily polluted rivers in rapidly urbanizing areas. Optimization models are widely used to determine the pollutant removal levels at different pollution sources, with the aim of minimizing...
