• New research shows how complex chemistry may be relevant to origins of life on Earth
  

  Chemists have long sought to understand the origins of life, with one popular model suggesting life began when simple RNA molecules capable of copying themselves formed spontaneously in the primitive environment. How this happened exactly is fraught with difficulties. New research by a team of chemi more

• Experiment shows for the first time in detail how electrolytes become metallic
  

  An international team has developed a sophisticated experimental technique at BESSY II to observe the formation of a metallic conduction band in electrolytes. To accomplish this, the team first prepared cryogenic solutions of liquid ammonia containing different concentrations of alkali metals. The c more

• How particulate matter arises from pollutant gases
  

  When winter smog takes over Asian mega-cities, more particulate matter is measured in the streets than expected. An international team, including researchers from Goethe University Frankfurt, as well as the universities in Vienna and Innsbruck, has now discovered that nitric acid and ammonia in part more

Industrial implementation of the ammonia synthesis - How does it work?

In September 1913, the first industrial-scale ammonia production plant came on stream at BASF in Ludwigshafen. The Haber-Bosch process for ammonia synthesis, which was first successfully operated at BASF Ludwigshafen in September 1913, was the decisive step into the age of mineral fertilizers. T ... 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

The Chemistry of the Smell of Toilets & Human Waste

Today’s post marks a slight detour for the aroma chemistry series. So far, we’ve look mainly at pleasant aromas, but today we turn to a major malodour: that of toilets, and, more specifically, human waste. It might seem like something of a childish subject, but there are some interesting chemical co more

The Chemistry of Permanent Hair Dyes

Today, hair dyes are widely used, either to cover up grey hairs, or simply by those wanting to change their natural hair colour. The chemistry behind how they change the colour of hair can actually get pretty complicated, but this graphic tries to boil it down to the key classes of chemicals involve more

• Size structure–catalytic performance correlation of supported Ni/MCF-17 catalysts for COx-free hydrogen production

  Herein, supported Ni/MCF-17 catalysts with the size of nickel nanocrystal in the range of 1.5–8.0 nm were synthesized and employed for COx-free hydrogen production for fuel cells via the ammonia decomposition reaction. Characterized by a variety of techniques, the results show that nickel particles more

• Modulating D-amino acid oxidase (DAAO) substrate specificity through facilitated solvent access

  by Kalyanasundaram Subramanian, Artur Góra, Ruud Spruijt, Karolina Mitusińska, Maria Suarez-Diez, Vitor Martins dos Santos, Peter J. Schaap D-amino acid oxidase (DAAO) degrades D-amino acids to produce α-ketoacids, hydrogen peroxide and ammonia. DAAO has often been investigated and engineered for more
