Developments in Nmr in Liquid Crystalline Solvents

This paper describes some recent developments in the technique of molecular structure determination from nmr in liquid crystalline solvents. 1. An INDOR double resonance method, which can be helpful in the analysis of complex spectra, is described and applied to the spectrum of bicyclobutane. 2. In more complex molecules, extensive overlap of peaks can make interpretation impossible. It is show...

Phytoestrogens: recent developments

Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...

On recent developments in marginal separation theory

Thin aerofoils are prone to localized flow separation at their leading edge if subjected to moderate angles of attack α. Although 'laminar separation bubbles' at first do not significantly alter the aerofoil performance, they tend to 'burst' if α is increased further or if perturbations acting upon the flow reach a certain intensity. This then either leads to global flow separation (stall) or t...

Some Recent Developments in Methods of Separation

Separation methods are being applied more extensively than ever before, particularly in trace analysis. Some of the more interesting procedures which have recently been proposed in solvent extraction and ion-exchange chromatography are reviewed, together with other new procedures for separation based on classical techniques. The possibilities of gas chromatographic separation of metal chelates ...
