Red phosphorus, usually in amorphous form, is obtained by heating liquid white phosphorus at a temperature of between 250° and 590. degree. C. while the phosphorus is subjected to a pressure greater than the theoretical vapor pressure of white phosphorus at the heating temperature. The ...
an allotropic modification of phosphorus, obtained as a dark red powder by heating ordinary phosphorus in closed vessels. It is not poisonous, is not phosphorescent, and is only moderately active chemically. It is valuable as a chemical reagent, and is used in the composition of the friction su...
SEM micrographs of the carbonized electrospun carbon fibers (a, b) and of the same fibers after the RP drop-casting insertion process (c, d); false colors elemental EDS mapping of the fiber mat decorated with phosphorus (e). In the EDS mapping, carbon is highlighted in orange and phosphoru...
Physical and chemical treatment of red mud, such as heating, seawater neutralization, treatment with HCl or H2O2 are all reported to greatly improve its adsorption capacity (Table 7). Increased adsorption efficiency can also be achieved by ensuring the solution pH is greater than 5 (Gupta and ...
Ginseng red skin root syndrome (GRS) is one of the most common ginseng (Panax ginseng Meyer) diseases. It leads to a severe decline in P. ginseng quality and seriously affects the P. ginseng industry in China. However, as a root disease, the characterist
The compounds of the first preferred class in which X is sulphur can be prepared by heating an octa-halo-phthalocyanine, in which at least six, and more preferably all, of the halogen atoms are attached to 3,6 carbon atoms, with at least eight equivalents of an organic thiol in an organ...
Thirdly, damage to the red blood cells was examined by flow cytometry where the proportion of intact cells in a sample can be counted using a fluorescent marker. Incubations of 5, 15 and 30 minutes were performed for the same three incubation methods: room temperature, heating block and th...

Exudation provides a valuable source of Carbon, while microorganisms that colonize the rhizosphere help plants to acquire Phosphorus and Potassium, and some enhance Nitrogen uptake, or even help the plants to cope with infection, toxic compounds, and other sources of stress (Kristensen et al., ...
