X-ray analysis of carbon nanostructures helps material design

NanoWerk.com - Thu, 03/14/2019 - 01:34
Nanostructures made of carbon are extremely versatile: they can absorb ions in batteries and supercapacitors, store gases, and desalinate water. How well they cope with the task at hand depends largely on the structural features of the nanopores. A new study has now shown that structural changes that occur due to morphology transition with increasing temperature of the synthesis can also be measured directly -- using small-angle X-ray scattering.

DNA and RNA Copying made easy

ScienceDaily.com: Nanotechnology News - Tue, 03/12/2019 - 20:36
Whether revealing a perpetrator with DNA evidence, diagnosing a pathogen, classifying a paleontological discovery, or determining paternity, the duplication of nucleic acids (amplification) is indispensable. Scientists have now introduced a new, very simple, yet highly sensitive and reliable method that avoids the usual heating and cooling steps, as well as complicated instruments. The reagents can be freeze-dried, allowing this universal method to be used outside of the laboratory.
