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, ...

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 ...

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 ...

Helpful Oxygen Carriers

19-Feb-2020

Enzymes with flavin cofactor play an important part in plants, fungi, bacteria and animals: as oxygenases they incorporate oxygen into organic compounds. For instance this allows people to excrete foreign substances more effectively. Until now scientists were agreed that such flavin-dependent ...

Researchers observe quantum interferences in real-time using a new extreme ultra-violet light spectroscopy technique

18-Feb-2020

A team headed by Prof. Dr. Frank Stienkemeier and Dr. Lukas Bruder from the Institute of Physics at the University of Freiburg has succeeded in observing in real-time ultrafast quantum interferences — in other words the oscillation patterns — of electrons which are found in the atomic shells of ...

Researchers investigate ultrafast reaction of superfluid helium triggerd by extreme ultraviolet laser pulses

10-Jan-2020

A team headed by Professor Frank Stienkemeier at Freiburg’s Institute of Physics and Dr. Marcel Mudrich, professor at the University of Aarhus in Denmark, has observed the ultrafast reaction of nanodroplets of helium after excitation with extreme ultraviolet radiation (XUV) using a free-electron ...

Main-group atoms often occur in small clusters, which can be neutral, negative or positive charged. The best known neutral cluster-tetrahedron is white phosphorus (P4), but other tetrahedra can also be isolated. They are four-atom molecules whose spatial arrangement corresponds to a tetrahedron ...

Researchers present useful ideas for 3D printing

08-Oct-2019

Plastic could soon be saying goodbye to its bad reputation. A working group headed by Professor Rolf Mülhaupt at the Freiburg Materialforschungszentrum (FMF) is currently developing “single-polymer composites” that can be produced from both fossil and renewable raw materials and later recycled ...

Researchers succeed in printing channel structures in glass

02-Apr-2019

Quartz glass is the preferred material for applications that require long-term use because of its high chemical and mechanical stability and excellent optical properties. The engineer Prof. Dr. Bastian E. Rapp from the Department of Microsystems Engineering (IMTEK) at the University of Freiburg ...
