Electrochemiluminescence (ECL) of a boron difluoride formazanate dye was investigated in the presence of tri-n-propylamine as a reductive co-reactant. The ECL mechanism was studied using ECL-voltage curves, spooling ECL, and accumulative ECL spectroscopy. The ECL occurs at 724 nm by three distinct, voltage-dependent mechanisms of light emission.

A novel microfluidic fabrication technique which allows in situ formed silicon microchannels and does not necessitate substrate bonding is presented. A gas-permeable polymer membrane acts as the top surface of the microchannel, allowing xenon difluoride (XeF2) etchant to pass unobstructed to the silicon substrate. Exposed silicon areas on the wafer are then etched isotropically.

The structure and mechanical properties of crystalline materials of three boron difluoride dibenzoylmethane (BF2dbm) derivatives were investigated to examine the correlation, if any, among mechanochromic luminescence (ML) behaviour, solid-state structure, and the mechanical behaviour of single crystals. Qualitative mechanical deformation tests show that the crystals of BF2dbm( (t) Bu)2 can be b...

We demonstrate a straightforward surface micromachining process for the rapid prototyping of thin 'chip-edge' silicon microcantilevers protruding from edge silicon-on-insulator chip. The uses single photolithographic mask-with xenon difluoride used to both pattern and release them by etching part underlying wafer. During step, are protected combination photoresist buried dioxide. use common mic...

Purpose: Recurrent aphthous stomatitis (RAS) is the most common painful ulcerative disease of oral mucosa happening in ~20% of people. Aimed to develop Myrtus communis L. (Myrtle) containing oral patches, we applied box-behnken design to evaluate the effect of polymers such as Polyvinyl pyrrolidone (PVP), Gelatin, Methylcellulose (MC) and Pectin. Methods: The patches properties such as tensile ...
