Producing Hydrogen and Fertilizer at The Same Time
Producing Hydrogen and Fertilizer at The Same Time
This new concept could allow the needs of previously separate industries to be combined. A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the production of fertilizer have so far been separate chemical processes.

An optical lens that senses gas
An optical lens that senses gas
A research team from the University of Jena has developed a small optical lens, only a few millimetres in size, whose refractive behaviour changes in the presence of gas. As reported by the researchers in the journal Nature Communications, this "intelligent" behaviour of the micro-lens is enabled by the hybrid glass material from which it is made.

Golden Ball Mills as Green Catalysts
Golden Ball Mills as Green Catalysts
Less waste, mild reaction conditions, and no harmful solvents - only a very thin layer of gold is necessary to sustainably convert alcohols into aldehydes through mechanochemistry. A gold-coated milling vessel for ball mills proved to be a real marvel in the research work by Inorganic Chemistry at Ruhr University Bochum, Germany: Without any solvents or environmentally harmful chemicals, the team led by Professor Lars Borchardt was able to use it to convert alcohols into aldehydes.

Paving the Way for Hydrogen from Algae Enzymes
Paving the Way for Hydrogen from Algae Enzymes
A research team from Bochum has identified a crucial detail that's essential for the production of hydrogen using biocatalysts. Under certain conditions, some algae are able to produce hydrogen - a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present.

Cancer Research: DNA Repair Mechanism Further Elucidated
Cancer Research: DNA Repair Mechanism Further Elucidated
Researchers at the University of Würzburg, led by Caroline Kisker in cooperation with Claudia Höbartner, discovered how the protein XPD detects a severe DNA damage and controls its repair. The XPD protein is a central component of our body's own 'DNA repair team', known as nucleotide excision repair (NER).

New Insights Into the Evolution of the Prion Protein
New Insights Into the Evolution of the Prion Protein
A study from Bochum describes a mammal-specific domain of the prion protein and offers new approaches for research into neurodegenerative diseases. At first, they cause memory deficits and difficulties in walking, finally they inhibit elementary motor skills and destroy basic brain functions: Prion diseases are progressive and invariably fatal neurodegenerative diseases.

New method for introducing fluorinated components into molecules
New method for introducing fluorinated components into molecules
A team of chemists at the University of Münster has developed a synthesis method for the site-selective integration of the biologically relevant difluoromethyl group into pyridines The difluoromethyl group often determines the properties of bioactive molecules and is therefore particularly interesting for drug research.

International research team cracks a hard physics problem
International research team cracks a hard physics problem
Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved by an international team of researchers from Germany, Turkey, the USA, China, South Korea and France using the new method of wavefunction matching.

How to Make Ubiquitous Plastics Biodegradable
Understanding the function of a specific bacterial enzyme has paved the way for the biotechnological degradation of styrene. Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process.

New Function of Oncoproteins
Researchers at the University of Würzburg have discovered a new function of the oncoprotein MYCN: It not only helps cancer cells to grow stronger, but also makes them more resistant to drugs. Oncoproteins are actually vital to human survival: thousands of them in our bodies ensure that cells grow and divide.

Safer alternative for an explosive reaction
Safer alternative for an explosive reaction
For over 100 years, the chemical industry has been using explosive aryl diazonium salts to produce paints, for example. A team from the Max Planck Institute for Coal Research has now discovered a safer alternative for the processes in which the chemical is used. The researchers are mimicking a reaction that plants use to reduce nitrate, using chemicals that the chemical industry uses to produce fertilizers - which could also make the processes more cost-effective.
