The mechanisms of floating and sliding of liquid marbles are studied. Liquid marbles containing CaCl(2) and marbles containing NaOH water solutions float on water containing Na(2)CO(3) and an alcoholic solution of phenolphthalein with no chemical reaction. Sliding of liquid marbles

In this paper, we report the fabrication of carbonaceous nanofiber (CNF) membranes functionalized by beta-cyclodextrins (CNF-β-CD membrane) and their application for molecular filtration. The chemically synthesized carbonaceous nanofibers were first functionalized by β-CD, and the free-standing CNF membrane can be

Electrospinning has been used to successfully create polystyrene (PS) nanofibers containing either of three different types of cyclodextrin (CD); α-CD, β-CD, and γ-CD. These three CDs are chosen because they have different sized cavities that potentially allow for selective inclusion

To identify specific bacterial thymidylate synthase (TS) inhibitors, we exploited phenolphthalein (PTH), which inhibits both bacterial and human enzymes. The X-ray crystal structure of Lactobacillus casei TS (LcTS) that binds PTH showed multiple binding modes of the inhibitor, which prevented

Desorption corona beam ionisation (DCBI), the relatively novel ambient mass spectrometry (MS) technique, was utilised to screen for illicit additives in weight-loss food. The five usually abused chemicals - fenfluramine, N-di-desmethyl sibutramine, N-mono-desmethyl sibutramine, sibutramine and phenolphthalein - were detected
