New substance classes for nanomaterials

Nano spheres and diamond slivers made of silicon and germanium

09-Sep-2021

Chemists at Goethe University Frankfurt have developed two new classes of materials in the field of nanomaterials and investigated them together with their cooperation partners at the University of Bonn: for the first time, they have succeeded in producing a nano sphere of silicon atoms and a ...

How diphosphorus can be used for chemical reactions

Team from Göttingen and Frankfurt succeeds in stabilisation

29-Jul-2021

Chemical syntheses of new active ingredients or functional materials are based on the use of molecular building blocks. These must be simultaneously reactive but also stable enough to enable targeted incorporation into larger molecules. A research team from the University of Göttingen and the ...

How nitrogen is transferred by a catalyst

The detailed understanding will allow for the design of catalysts tailored for specific reactions

16-Nov-2020

Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation. The key compound in a catalytic nitrogen-atom transfer reaction has ...

Snapshot of exploding oxygen

New experimental technique with reaction microscope allows “X-ray” of individual molecules

11-Jun-2020

For more than 200 years, we have been using X-rays to look inside matter, and progressing to ever smaller structures – from crystals to nanoparticles. Now, within the framework of a larger international collaboration on the X-ray laser European XFEL in Schenefeld near Hamburg, physicists at ...

How particulate matter arises from pollutant gases

International research project observes ultrafast particle growth through ammonia and nitric acid

15-May-2020

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 ...

First machine-generated chemistry book published

Cooperation between Applied Computational Linguistics lab of Goethe University and Springer Nature

16-Apr-2019

Springer Nature published its first machine-generated book, compiled using an algorithm developed by researchers from Goethe University. This collaboration broke new ground with the first machine-generated book to be published by a scholarly publisher. The book is available as a free download ...

Inert Nitrogen Forced to React with Itself

26-Mar-2019

Direct coupling of two molecules of nitrogen: chemists from Würzburg and Frankfurt have achieved what was thought to be impossible. This new reaction is reported in Science magazine and opens new possibilities for one of the most inert molecules on earth. Constituting over 78 % of the air we ...

Duplicate or mirror? Laser light determines chirality of molecules

19-Mar-2019

Seven of the ten most frequent medications contain chiral agents. These are molecules that occur in right- or left-handed forms. During chemical synthesis both forms usually occur in equal parts and have to be separated afterward, because chirality determines the agent’s effect in the body. ...

Made-to-measure silicon building blocks

26-Jul-2018

The broad spectrum of applications for silicones ranges from medical implants and cosmetics to hydraulic oils and sealants to corrosion protection – an important topic in view of global corrosion damage to the tune of about US$ 3.3 trillion per year. To optimize silicon-based synthetic materials ...

Molecular libraries for organic light-emitting diodes

25-Apr-2017

Organic light-emitting diodes (OLEDs) are promising candidates for flexible flat displays. By means of a screening process developed by chemists at Goethe University Frankfurt, it is now possible to identify more quickly lead structures with superior luminescence and charge-transport properties. ...
