Extraction equilibria of nicotinic acid using Alamine 300/diluent and conventional solvent systems
, 2002 The distribution of nicotinic acid between water and Alamine 300 (tri-n-octylamine) dissolved in various (proton-donating and -accepting, polar and nonpolar) diluents, and a comparison with the extraction equilibria of pure diluent alone were studied at ...

Molecular characterisation of insect nicotinic acetylcholine receptors [PDF]
, 2003 Nicotinic acetylcholine receptors (nAChRs) are pentameric multi-subunit proteins that form ligand-gated ion channels in the central nervous systems of vertebrates and invertebrates and at the neuromuscular junction of vertebrate species. In insects, they
