Assembly of the coat protein I (COPI) vesicle coat is controlled by the small GTPase ADP ribosylation factor 1 (ARF1) and its GTPase-activating protein, ARFGAP1. Here, we investigate the diffusional behaviours of coatomer, the main component of the coat, and also those of ARF1 and ARFGAP1. Using fluorescence-correlation spectroscopy, we found that most ARF1 and ARFGAP1 molecules are highly mobi...

Coating the inner surfaces of high-powered plasma processing equipment has become crucial for reducing maintenance costs, process drift, and contaminants. The conventionally preferred alumina (Al2O3) coating been replaced with yttria (Y2O3) due to long-standing endurance achieved by fluorine-based etching; however, continuous increase in radio frequency (RF) power necessitates use alternative m...

The development of high-quality fluoride-ion transporting electrolytes is a crucial demand for fluoride shuttle batteries (FSBs). However, the uncontrolled chemical and electrochemical activities ions narrow available potential window, hindering high-voltage FSB cells. We present method upgrading recently developed lactone-based liquid by complexation F – with Li + Mg 2+ ions. In resultant /F h...

a flow injection system is reported for the determination of fluoride based on its effects on the fluorescence intensity of al-morin complex at ph 3.0 in ethanol-warn mixture. the effect of important parameters such as excitation and emission wavelengths, ph, reagents concenkations, flow rate of the carrier stream, sample injection volume, time of measurepent and interferences are reported. cat...

statement of the problem generally, the main source of fluoride intake is drinking water. excessive consumption of bottled water as a substitute or in addition to the tap water supply may have implications for safe fluoride supplementation. in this study, fluoride contents in six commercial brands of bottled water were measured materials and methods six different brands of bottled drinking wate...
