Phosphorus has diverse chemical bonds, and even in its two-dimensional form, there are three stable allotropes: black phosphorene (Black-P), blue (Blue-P), violet (Violet-P). Due to the complexity of these structures, no efficient accurate classical interatomic potential been developed for them. In this paper, we develop an machine-learned neuroevolution model allotropes apply it study thermal ...

A basic dye is usually obtained in the form of the salt some of which may be transformed in aqueous solution to free base (the m o u n t depending on the "apparent" dissociation constant of the dye and the pH value), and in the range of pH values generally employed with living cells (approximately between pH 5 and 9.5) both forms of dye must be considered. In this range methylene blue, for exam...

Lactase activity was detected in a culture medium of the cell suspension culture of watermelon (Citrullus vulgaris L.). A simple, rapid and reproducible procedure for identification of extracellular lactase is described using callus cultures of seedlings from the tested plant, hairy roots of 2.5 days old seedlings of watermelon germinating on agar plates as well as cell suspension cultures deri...

In 1891 Ehrlich demonstrated the antimalarial activity of methylene blue and a few years later discovered that trypan red would kill trypanosomes. These disclosures helped lay the foundations of chemotherapy. Since that time many workers have studied the effects of dyes on microorganisms, among them Stearn and Stearn (1924). Dion and Lord (1944) and Aiquel and Herraro (1948) have shown that bas...

BACKGROUND Low power violet laser diodes (VLDs) have been evaluated as potential replacements for water-cooled argon-ion and krypton-ion ultraviolet and violet lasers for DNA content analysis using the Hoechst dyes and 4,6-diamidino-2-phenylindole (Shapiro HMN, Perlmutter NG: Cytometry 44:133-136, 2001). In this study, we used a VLD to excite a variety of violet-excited fluorescent molecules im...

Burkholderia cepacia complex (BCC) represent a group of opportunistic organisms that cause wide variety infections including the nosocomial. The organism is found to sepsis and also reported blood stream in malignancy. Here, we present case series five patients with which an unsual violet pigment producing BCC was isolated. Keywords: Violet pigment, Burkholderia, Sepsis, Malignancy

This research examined the production of a V2O5-g-C3N4 nanocomposite to remove organic dyes from wastewater. To generate nanocomposite, sonication method was applied. The testing with various (basic fuchsin (BF), malachite green (MG), crystal violet (CV), Congo red (CR), and methyl orange (MO)) revealed that has high adsorption ability towards BF, MG, CV, CR in comparison MO dye. It established...
