Nicotine proteome effects: Tissue-specific alterations

Date: Jun 1, 2018

Author: Steve Down

US scientists have found that up to 126 proteins in seven tissue types were affected by oral exposure of mice to nicotine, sending warning signals to consumers who smoke electronic cigarettes under the misapprehension that they are safe.

Very volatile organic compounds: Indoor air testing

Date: Jun 1, 2018

Author: Steve Down

A new thermal desorption-GC/MS procedure has been developed by scientists in Germany for the determination of very volatile organic compounds in indoor air, but it must be supplemented by at least two other methods to include the full range of compounds.

Insider view: X-rayed battery life

Date: Jun 1, 2018

Author: David Bradley

A three-dimensional X-ray tomographic study carried out by researchers from the University of Illinois to investigate lithium battery electrodes could improve our understanding of this almost ubiquitous technology and perhaps lead to improvements in storage capacity and battery lifespan.

Unravelling spider silk: UV technique weaves the clues

Date: Jun 1, 2018

Author: David Bradley

Scientists at RIKEN in Japan have used far-UV circular dichroism spectroscopy and other techniques to reveal the underlying mechanism of spider silk formation. The research could help materials scientists weave biomimetic versions of this natural material which is both stronger and more flexible weight-for weight than steel.

Raman breath test: Detecting illicit drugs

Date: Jun 1, 2018

Author: David Bradley

An inexpensive and yet high-performance chip based on surface-enhanced Raman spectroscopy (SERS) can test for illicit drugs such as cocaine, opioids, and marijuana as quickly as a breathalyzer can detect alcohol.according to new research from the USA. The device can quickly reveal such drugs in for samples of blood, urine, saliva, and even on the breath.
