There have been a considerable number of studies on alkali molecular diffuse bands concerning their excimertype nature.’ Such diffuse bands might be developed as possible sources of tunable, high-power lasers.2 Fluorescence of a Naa violet diffuse band could be observed either by one-photon excitation of X’c,’ w C’II, or two-photon excitation of an X’c,’ -+ A’C: -+ high-lying g state in Na,, or...

Prominent progress has been made in nitride semiconductor since high bright blue LED has developed in 1993. It has also expanded to an industry after applied to white LED. These LEDs are produced by the epitaxial growth of nitride semiconductor layers on sapphire (a Al2O3) substrate. On the other hand, recording density in optical disks has increased from CD in 1980s to DVD in latter 1990s. Las...

The effect of acid-alkaline treatment of lignocellulosic material (wild carob forest wastes) on Ethyl violet adsorption was investigated. It was found that surface chemistry plays an important role in Ethyl Violet (EV) adsorption. HCl treatment produces more active acidic surface groups such as carboxylic and lactone, resulting in an increase in the adsorption of EV dye. The adsorp...

Sustainable chemistry is a relatively new field that aims to achieve both economic and environmental goals simultaneously. This paper discusses cleaner more sustainable method for dyeing cotton fabric using Direct Violet 09 Reactive 05 dye. It has been noticed good color characteristics were obtained when was dyed with 35 mL of microwave-treated dye solution 7 pH 2 g Aluminum sulfate 30 min at ...

The ability of 0.1% Trypticase (BBL) to maximize recovery of frozen Escherichia coli on Violet Red Bile Agar is presented.

A sensitive and selective amperometric sensing platform for lead (Pb(2+)) was developed based on a Pb(2+)-induced G-rich DNA conformational switch from a random-coil to G-quadruplex (G4) with crystal violet as the G4-binding indicator.

1. The behavior of a single bacterial cell toward gentian violet differs fundamentally from that of a small group of cells (thirty). 2. The explanation of this phenomenon is not purely quantitative; thirty cells accomplish much more than thirty times what one cell can accomplish.
