Novel 6-pyridyl substituted pyrimidine derivatives are disclosed for use as antiviral agents, particularly for the treatment of retroviral infections such as HIV infections and related disorders, as well as for use in anti-cancer therapies to improve the efficacy of anti-cancer therapeutics. These ...
Sulfur dioxide(二氧化硫)is an important compound in its own right。It is used in the manufacture of paper。When made from wood pulp or from other materials,paper is usually pale yellow in colour。 Sulfur dioxide is used to bleach(漂白)it to the white colour which is needed。Sulfur dioxide ...
The meaning of SULFUR TRIOXIDE is a compound SO3 that is a heavy low-boiling strongly acid corrosive liquid when first produced at ordinary temperatures but that polymerizes readily to three or more solid forms including a stable modification resembling
A silver vanadate compound was developed to be used in a permanent combustion tube packing for carbon-hydrogen analyzers. The material demonstrates increased activity and greater capacity for containing sulfur and the halogens. Silver vanadate also acts as an indicator for signaling its depletion. Anal...
Does sulfur replace oxygen in the superconducting YBa 2 Cu 3 O 6 S phase?doi:10.1016/0038-1098(88)90766-1Electron microscopy studies indicate a sulfur containing phase of approximate composition YBa2Cu3O6S in "fresh" samples. This compound is superconducting and its Tc is 91 K. Its phase ...
PROBLEM TO BE SOLVED: To simply and effectively perform the oxidation treatment of an aq. solution contg. an oxidizable sulfur-oxygen compound on an industrial scale by adding an excess amount of sodium peroxodisulfate to a feed solution contg. a specified amount of a sulfite to convert it in...
Similarly, other investigators hinted that a combination of environmental factors, including light quality and quantity and sulfide and oxygen concentrations, need to be considered when evaluating the competitive position between CSB and PSB (Jørgensen and Des Marais, 1986). In further investigations,...
Interestingly, yeasts undergoing SAAR upregulated MET1, MET3, MET5, and MET10 genes which are associated with increased H2S production (Choiet al., 2019). However, SAAR failed to increase H2S production in mutant strains, but still extended chronological lifespan and reducedreactive oxygen speci...
(HS−), and sulfur. Reduced sulfur compounds are usually formed as a product of anaerobic heterotrophic respiration with sulfate, but some waters receive large inputs of sulfide via ground water. Oxygen is the most common electron acceptor, but other potential electron acceptors such as nitrate ...
