Cephalopods can display dazzling patterns of colours by selectively contracting muscles to reversibly activate chromatophores--pigment-containing cells under their skins. Inspired by this novel colouring strategy found in nature, we design an electro-mechano-chemically responsive elastomer system that can exhibit a wide

The oxidation of o-xylene by P450(BM3) from Bacillus megaterium yields, in addition to the products formed by microsomal P450s, two metabolites containing an NIH-shifted methyl group, one of which lacks the aromatic character of the substrate. The failure of the

We present a colourimetric litmus test for simple differentiation of organic liquids based on wetting, which achieves chemical specificity without a significant sacrifice in portability or ease-of-use. Chemical specificity is derived from the combination of colourimetric wetting patterns produced by

Whereas benzene (BZ) is a well-known human carcinogen, toluene (TOL) and o-xylene (o-XY) are not; however, all three compounds are important environmental pollutants. Although BZ, TOL, and o-XY have been shown to induce apoptosis in vitro, their mechanism of toxicity

A completely β-selective glycosylation that does not rely on neighboring group participation is described. The novelty of this work is the design of the glycosyl donor locked into the axial-rich form by the o-xylylene bridge between the 3-O and 6-O

  2. What are the percentages of each Xylene isomer found in product 320579, Xylene?

    1 answer
    1. According to data given by the supplier of product 320579, Xylenes, this product contains a minimum of 18.0% p-Xylene and no more than 20.0% Ethylbenzene (we allow for </= 25.0% on our Certificate of Analysis).  Both o- and m-Xylene are reported as batch-specific values and will not have to meet a requirement as long as the sum of all Xylene isomers and Ethylbenzene are equivalent to 98.50% or more. In several batches, m-Xylene has appeared with a value of ~40% and o-Xylene with ~20%.  These values may change on a batch-to-batch basis.*All percentages above are "wt %".
