General description

Dichloromethane has been tested as a solvent medium for dipyridine-chromium(VI) oxide. Solubility was reported to be 12.5g/100ml. Role of the quantity of TiO2 loading on activated carbon support on dichloromethane photodecomposition has been investigated.

Application

Dichloromethane may be used in ultrasonic baths for cleaning and protection of aluminum coating over atactic-PMMA (poly(methyl methacrylate)) for dielectric studies.

Recent research suggests that plant viruses, and other pathogens, frequently alter host-plant phenotypes in ways that facilitate transmission by arthropod vectors. However, many viruses infect multiple hosts, raising questions about whether these pathogens are capable of inducing transmission-facilitating phenotypes in...
