• Chemours Announces Participation in Versogen’s Development of Clean Hydrogen Technology
  

  The Chemours Company announced its participation in a fundraising for Wilmington, Delaware-based Versogen Inc., a start-up in developing anion exchange membrane (AEM) technology for use in hydrogen production. Founded by University of Delaware professor Yushan Yan, Versogen’s AEM technology offers a more

• Reference-factory.H2 – electrolyzer and fuel cell production of the future
  

  Hydrogen is a key element in the energy transition. To ensure that hydrogen can become generally established as an energy source, it must be produced at market prices, in sufficient quantities and in a climate-neutral manner, and used with a high CO2 reduction rate. This requires affordable, robust more

• New system based on protonated ceramic membranes produces hydrogen industrially
  

  An international team involving the Institute of Chemical Technology (ITQ), a joint center of the Spanish National Research Council (CSIC) and the Polytechnic University of Valencia (UPV), has developed a new electrified reactor to obtain hydrogen in a more sustainable and energy-efficient way. This more

• CO2 Gas Calibration with eVol®, the digital analytical syringe
  

  Using eVol® for injection of different volumes of CO2, CEP/TEP was able to achieve calibration of their instrument with levels of accuracy and precision not previously obtained using manual syringes. In addition, the needles on the eVol® syringes all more

The Atmospheres of the Solar System

We’re heading out of this world for today’s post, to examine the atmospheric compositions of the other planets in the solar system, as well as our own. Practically every other planet in our solar system can be considered to have an atmosphere, apart from perhaps the extremely thin, transient atmosph more

A Guide to Acids, Acid Strength, and Concentration

Even if you’re not a chemist, you’ll doubtless remember learning about acids back in school. They’re routinely described as strong or weak, concentrated or dilute. But what’s the difference between a strong acid and a concentrated acid? Explaining that is a little trickier than it sounds; in this gr more

The biggest stories in science 2017

As we head into 2018, it’s time to take a look back at some of the biggest science news stories over the past year. This year’s science news featured poisonous frogs, battery fires, element creation, and more! more

• Atomic hydrogen interactions with gas-phase coronene cations: hydrogenation versus fragmentation

  Sequential hydrogenation of polycyclic aromatic hydrocarbon (PAH) cations drives a gradual transition from a planar to a puckered geometry and from an aromatic to an aliphatic electronic structure. The resulting H-induced weakening of the molecular structure together with the exothermic nature of th more

• On the gas-phase formation of the HCO− anion: Ac- curate quantum study of the H−+CO radiative associ- ation and HCO radiative electron attachment

  The hydrogen anion has never been observed in the interstellar medium, but it is most likely present in some interstellar regions. Since a direct detection appears especially difficult, im- proving the knowledge of the astrochemical processes involving this anion should be valuable in defining a way more

• Drastic rearrangement of self-assembled hydrogen-bonded tapes in a molecular crystal

  A 2 : 1 hydrogen-bonded crystal of 2-pyrrolidone and chloranilic acid shows structural phase transitions accompanied by the drastic rearrangement of hydrogen-bonded tapes. Such a phenomenon is attributed to the selective and directional character of hydrogen bonds. more
