Novel quantum effect discovered in naturally occurring graphene

International research team finds atomically-thin carbon generates its own magnetic field

08-Oct-2021

Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of the basic material properties and “quantised” (meaning that it changes in ...

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 ...

Eco-friendly plastic from cellulose and water

Researchers create new kind of environmentally friendly bioplastic with hydroplastic polymers

26-Jul-2021

Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics are simply not sustainable, and pose a major global threat to the environment and human health. Eco-friendly ...

High-resolution microscope built from LEGO and bits of phone

Research shows constructing microscope improves children’s understanding - enlightening, educational and fun

06-Jul-2021

Microscopy is an essential tool in many fields of science and medicine. However, many groups have limited access to this technology due to its cost and fragility. Now, researchers from the Universities of Göttingen and Münster have succeeded in building a high-resolution microscope using nothing ...

Better Understanding Membranes

A new class of membranes promises highly interesting applications in material separation, whether in biotechnology or water purification

28-May-2021

The theoretical understanding of these polymer membranes is, however, still incomplete. Two researchers from Helmholtz-Zentrum Hereon and the University of Göttingen now present a study, published in the renowned science journal Chemical Reviews, that identifies these gaps in knowledge and shows ...

Crystal structures in super slow motion

Researchers first to succeed in filming a phase transition with extremely high spatial and temporal resolution

26-Jan-2021

Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they ...

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 ...

‘Whispering gallery’ effect controls electron beams with light

Light can add functionality to electron microscopy

08-Jun-2020

When you speak softly in one of the galleries of St Paul’s cathedral, the sound runs so easily around the dome that visitors anywhere on its circumference can hear it. This striking phenomenon has been termed the ‘whispering gallery’ effect, and variants of it appear in many scenarios where a ...

A pigment from ancient Egypt to modern microscopy

Research team produces new nanosheets for near infrared imaging

25-Mar-2020

Egyptian blue is one of the oldest manmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen ...

Graphene layer enables advance in super-resolution microscopy

Eesearchers develop a new method allowing ten-fold improvement in optical resolution

05-Sep-2019

Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows scientists to optically measure extremely small distances, in the order ...
