Abstract

In this study is reported a simple and inexpensive method for concurrent determination of taurine and choline in different supplementary nutrient samples using dual-channeled capillary electrophoresis (CE) instrument with capacitively coupled contactless conductivity detection (C4D). The objective...

Abstract

In this work, a novel approach was developed to perform dispersive liquid-liquid microextraction using a rapid pressure variation to disperse the extraction solvent in an aqueous medium. A glass syringe was used to produce an environment subject to a rapid pressure difference. The element used as a ...

Abstract

Edible super-hydrophobic coatings have attracted great attentions as they can avoid the waste of liquid foods, such as honey and milk, adhered to the inside of containers. However, the poor thermal stabilities of edible super-hydrophobic coatings restrict their applications. In this work, a...

Abstract

A novel gas storage and release system was developed for ethylene, an exogenous plant hormone that regulates fruit ripening and senescence. This system consists of a metal organic framework (MOF) core and an alginate-based shell. The MOF comprises a coordination complex of Al and [btc]3- ligands,...

Abstract

High-performance measurement of methyl parathion (MP) is of great importance in both agricultural and environmental surveillance. Herein, we presented a facile fluorescent biosensor to indirectly measure MP using N-doped carbon dots (N-CDS) based on the inner filter effect (IFE). Methyl parathion...
