Companies Hydrogen
Westfalen AG, Germany
Westfalen Group: energy that gives more The Westfalen Group was founded in 1923 in Münster. With over 1,600 employees, in 2014 the family-run company led by Chairman of the Board Wolfgang Fritsch-Albert posted its best ever results with a turnover of around 1.8 billion euros. The company's activiti more

Linde to Build, Own and Operate World's Largest PEM Electrolyzer for Green Hydrogen
Linde announced it will build, own and operate the world's largest PEM (Proton Exchange Membrane) electrolyzer plant at the Leuna Chemical Complex in Germany. The new 24-megawatt electrolyzer will produce green hydrogen to supply Linde's industrial customers through the company's existing pipeline n more

Increasing the Activity of Catalysts
A layer as thin as a single atom makes a huge difference: On the surface of an electrode, it doubles the amount of water split in an electrolysis system without increasing the energy requirements. Thus, the ultrathin layer also doubles the amount of hydrogen produced without increasing costs. Resear more

Producing hydrogen from water
Efficiently mass-producing hydrogen from water is closer to becoming a reality thanks to Oregon State University College of Engineering researchers and collaborators at Cornell University and the Argonne National Laboratory. The scientists used advanced experimental tools to forge a clearer understa more

Battling Corrosion in Refineries
Corrosion in refinery operations has been, and still is, the subject of many studies, papers, courses and web forums. Although a lot of what has been written shows that significant progress in understanding corrosion has been made, it also makes it 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
