The article indicates that the sudden appearance (or disappearance?) of polymorphs can derail clinical programmes. Such an example occurred in the development of the anti-glioma drug temozolomide, ...

"Each new detection brings us closer to understanding the origins of complex organic chemistry in the universe — and perhaps, ...

Accordingly, we synthesized new examples of 1,3-thiazolium-5-thiolate mesoionic compounds, especially those with large AM1-TDHF calculated values for β (0). Figure 1 shows two groups, R A and R D, ...

Plants produce an astonishing variety of chemical substances. Most of these metabolites are involved in chemical ...

We’ve marked two important anniversaries in Chemistry World recently: 200 years since Michael Faraday first isolated benzene ...

Calculations and Example of Compound Return For example, suppose you started with an initial investment of $1,000. If you multiply 1,000 by 1.1 five times, that is, $1,000 x (1.1) 5, you will end ...

Novel Keggin heteropolyacid anion based Brønsted acidic ionic salts [SO3H(CH2)4Mim]nH3–nPMo12O40 (n = 1, 2, 3) were synthesized and used as catalysts in the nitration of aromatic compound in HNO3 (67% ...

Results are reported from an ongoing passive air monitoring study for polycyclic aromatic compounds (PACs) in the Athabasca oil sands region in Alberta, Canada. Polyurethane foam (PUF) disk passive ...
