TL;DR: Rice hulls, when coated with the reactive dye of Procion Red or Procion Yellow, were found to be highly effective for removal of many metal ions from aqueous solutions both in batch and column method as mentioned in this paper.

TL;DR: Sodium hydrotelluride was found to serve as a new efficient agent for selective reduction of α,β-unsaturated carbonyl compounds under mild reaction conditions.

TL;DR: The structures of two metabolites, isolated from the culture liquid of Alternaria porri, have been identified as zinnimidine and 5-(3′,3′-dimethylallyloxy)-7-methoxy-6-methylphthalide, the first reported isolation as a naturally occurring product.

TL;DR: The culture liquid of Alternaria porri afforded a novel benzoxazoeine derivative, porritoxin, whose structure was determined by spectroscopic methods and inhibited seedling growth in lettuce at a concentration of 10 ppm.

TL;DR: In this article, aldehydes were prepared from Grignard reagents in high yields using pentacarbonyliron as the carbonylating agent and this reaction was also found to be applicable to the synthesis of aldehyde-d.
