Abstract: Abuse of amphetamine-type stimulant (ATS) is increased in Japan. Most ATS has optical isomers and their stimulatory effects are different between optical active forms and racemic form. We ...

In his decades-long career in tech journalism, Dennis has written about nearly every type of hardware and software. He was a founding editor of Ziff Davis’ Computer Select in the 1990s, senior ...

Thalidomide, a drug once used to alleviate morning sickness in pregnant women, exhibits distinct properties due to its optical isomers* in the body: one isomer has a sedative effect, while the other ...

THE odour differences of optical isomers have been reviewed by Naves 1. To date, the most that has been observed is a slight difference in the strength or ‘note’, and this has often disappeared when ...

Abstract: Infrared spectroscopy and mass spectrometry have long been reported as the most selective analytical techniques. Sensitive laser-based detection schemes for infrared spectroscopy such as ...

If you have a fancy home theater system with a soundbar and surround sound speakers, then how you connect it to your TV is an important consideration. There are legacy options you may be more familiar ...

ABSTRACT: A method for the analysis of the optical purity of a series of chiral substituted tetrahydroisoquinolines (THIQs) was developed. The method is based on pre-column derivatization of the ...

Our current minimal optical simulation example contains a lot of code that could be simplified further. For example, by using a uniform volume and a pencil beam light source. This would make it easier ...

Isolation and purification of pure, active enantiomers is important in the development of active pharmaceutical ingredients and drug products. However, recovering the desired optical isomer from a ...

Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, ...
