The photoelectric effect in stereo
Fri, 22 Jun 2018 17:48:05 EDT
In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location of a photoionization event.

Uncovering lost images from the 19th century
Fri, 22 Jun 2018 17:47:59 EDT
Art curators will be able to recover images on daguerreotypes, the earliest form of photography that used silver plates, after a team of scientists learned how to use light to see through degradation that has occurred over time.

Low-cost plastic sensors could monitor a range of health conditions
Fri, 22 Jun 2018 17:47:19 EDT
An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases.

Biorenewable, biodegradable plastic alternative synthesized
Fri, 22 Jun 2018 17:45:03 EDT
Polymer chemists have taken another step toward a future of high-performance, biorenewable, biodegradable plastics. The team describes chemical synthesis of a polymer called bacterial poly(3-hydroxybutyrate) ­- or P3HB. The compound shows early promise as a substitute for petroleum plastics in major industrial uses.

Chemists teach an enzyme a new trick, with potential for building new molecules
Thu, 21 Jun 2018 17:25:21 EDT
Chemists have found a way to make a naturally occurring enzyme take on a new, artificial role, which has significant implications for modern chemistry, including pharmaceutical production.
