Binding of a second CO molecule observed

Researchers clarify another step in the mechanism of reduction of carbon monoxide through nitrogenase

15-Jun-2021

Through the biological fixation of the element nitrogen by the enzyme nitrogenase, organisms gain access to molecular nitrogen (N2) in the Earth‘s atmosphere, which is essential for building cellular structures. In addition, a vanadium-dependent variant of nitrogenase can reduce the toxic gas ...

Hybrid redox-flow battery with a long cycle life

Researchers use the abundant chemical element manganese as active material

02-Jun-2021

Redox‑flow batteries store electrical energy in chemical compounds that are dissolved in an electrolyte. They are a particularly promising alternative to lithium‑ion batteries as stationary energy storage. A team headed by Prof. Dr. Ingo Krossing from the Institute of Inorganic and Analytical ...

Glass injection molding

Researchers succeed in producing rapid, cost-effective and environmentally friendly material

13-Apr-2021

Glass is ubiquitous, from high-tech products in the fields of optics, telecommunications, chemistry and medicine to everyday objects such as bottles and windows. However, shaping glass is mainly based on processes such as melting, grinding or etching. These processes are decades old, ...

Breaking the limit

Researchers introduce new transition metal carbonyl complexes relevant to textbooks and applications

25-Jun-2020

Since the end of the 19th century, transition metal carbonyls have been an important and familiar class of compound in coordination chemistry and organometallic chemistry. In these materials, carbon monoxide molecules (CO) are bound to transition metals as the central atom. In this subject area, ...

Innocent and highly oxidizing

Chemists produce new oxidants as a tool for preparative chemistry

04-Jun-2020

Chemical oxidation, the selective removal of electrons from a substrate, represents one of the most important transformations in chemistry. However, most common oxidants often show disadvantages such as undesired side reactions. The chemist Marcel Schorpp and colleagues from the group of Prof. ...

How to control individual components of self-assembling molecular structures

08-May-2020

In the development of autonomous systems and materials, self-assembling molecular structures controlled by chemical reaction networks are increasingly important. However, there is a lack of simple external mechanisms that ensure that the components of these reaction networks can be activated in a ...

The origins of roughness

Origins of surface texture investigated

19-Feb-2020

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic ...
