Lightning and subvisible discharges produce molecules that clean the atmosphere

04-May-2021

Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by ...

International research team discovers new two-dimensional material using high-pressure technology

Producing a chemical compound in that was previously completely unknown

29-Apr-2021

An international team with researchers from the University of Bayreuth has succeeded for the first time in discovering a previously unknown two-dimensional material by using modern high-pressure technology. The new material, beryllonitrene, consists of regularly arranged nitrogen and beryllium ...

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 ...

Reducing Nitrogen with Boron and Beer

Chemists have achieved the conversion of nitrogen to ammonium at room temperature and low pressure using only light elements

16-Sep-2020

The industrial conversion of nitrogen to ammonium provides fertiliser for agriculture. Würzburg chemists have now achieved this conversion at room temperature and low pressure using only light elements. Humankind is reliant on the ammonium in synthetic fertiliser for food. However, producing ...

Nitrogen – an exception in the periodic system?

New high-pressure material discovered and a puzzle of the periodic table solved

03-Jun-2020

In the periodic table of elements there is one golden rule for carbon, oxygen, and other light elements. Under high pressures they have similar structures to heavier elements in the same group of elements. Only nitrogen always seemed unwilling to toe the line. However, high-pressure researchers ...

Atomic images reveal unusually many neighbors for some oxygen atoms

22-Oct-2019

The identification of new chemical bonds is crucial for the design of new material structures. A team led by Jani Kotakoski at the University of Vienna and Jannik Meyer at the University of Tübingen has found unexpected new configurations of oxygen and nitrogen in graphene. Direct images of the ...

Researchers discover stable high-energy material

16-Oct-2019

High-energy materials that can store very large amounts of chemical energy and release it when required are being sought for long-haul space travel worldwide. Nitrogen compounds in which several nitrogen atoms are linked by single bonds possess this ability. These compounds are difficult to ...

Chemists show it's hip to be square

Their synthetic azetidines could help simplify drug design for neurological diseases

13-Aug-2019

Rice University chemists want to make a point: Nitrogen atoms are for squares. The nitrogens are the point. The squares are the frames that carry them. These molecules are called azetidines, and they can be used as building blocks in drug design. The Rice lab of chemist László Kürti introduced ...

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 ...
