Quickly identify high-performance multi-element catalysts

Complex solid solution electrocatalyst discovery by computational prediction and high‐throughput experimentation

18-Feb-2021

Finding the best material composition among thousands of possibilities is like looking for a needle in a haystack. An international team is combining computer simulations and high-throughput experiments to do this. Catalysts consisting of at least five chemical elements could be the key to ...

A prognostic Alzheimer’s disease blood test in the symptom-free stage

Memory deficit is a normal side effect of aging. At what point does memory loss become pathological?

08-Jan-2021

Using a blood test, a German-Dutch research team has predicted the risk of Alzheimer’s disease in people who were clinically diagnosed as not having Alzheimer’s disease but who perceived themselves as cognitively impaired (Subjective Cognitive Declined, SCD). The researchers analyzed blood ...

Catalytic activity of individual cobalt oxide nanoparticles determined

Using a robotic arm

16-Dec-2020

Analyzing nanoparticles individually is a challenge precisely because they are so small. A new technique using electron microscopy and a robotic arm could make the process much easier. Precious metal-free nanoparticles could serve as powerful catalysts in the future, for example for hydrogen ...

Detecting bacteria with fluorescent nanosensors

Luminous carbon nanotubes detect pathogens – and are quick and easy to use

26-Nov-2020

Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods. A team headed by Professor Sebastian Kruß, formerly at ...

Measuring pH locally with terahertz spectroscopy

New method to determine a local pH value near a specific site of a biomolecule

24-Nov-2020

Nowadays, it is easy to determine an average pH for larger quantities of liquid. It is a challenge, however, to define a local pH value. Researchers at Ruhr-Universität Bochum have developed a new method to determine a local pH value near a specific site of a biomolecule. A reliable measurement ...

Attacking tumours directly on identification

Therapy and diagnostics of tumours in only one step is possible with the aid of so-called theranostic agents

04-Sep-2020

The combination of a biomolecule and a metal complex can target, bind, mark and damage cancer cells. A German-Spanish team has manufactured such a theranostic agent that visualises tumour cells by irradiation with visible light, and proved its effectiveness against lung cancer cells. Andres ...

Giant nanomachine aids the immune system

A small but important step towards a successful immune reaction is performed by an impressive nanomachine - Researchers use simulations to understand how it works.

31-Aug-2020

In order to kill diseased cells, our immune system must first identify them. The so-called peptide-loading complex plays a key role in this process. In collaboration with colleagues from Jülich, a research team at Ruhr-Universität Bochum has analysed this nanomachine in atomic detail. Cells that ...

Making enzymes fit for industrial applications

Biobased process for ammonia production

27-Aug-2020

Bacterial enzymes are often powerful but also very sensitive catalysts. To call up their performance, they therefore need a special environment. Researchers at Ruhr-Universität Bochum (RUB) have developed new techniques for efficiently coupling bacterial enzymes to electrodes. Together with a ...

Immune response to Sars-Cov-2 following organ transplantation

Even patients with suppressed immune systems can achieve a strong immune response to Sars-Cov-2: A test helps to adapt therapy following an infection

19-Aug-2020

A research team from the University Hospital at Ruhr-Universität Bochum (RUB) has developed a test that provides information on the immune response to the novel coronavirus in patients who need to take immunosuppressive drugs. This is necessary, for instance, following an organ transplantation. ...

Rapid test for the determination of antibodies against Sars-Cov-2

No elaborate biosafety precautions are necessary

03-Aug-2020

To determine immunity to Sars-Cov-2 and the effectiveness of potential vaccines, the amount of neutralising antibodies in the blood of recovered or vaccinated individuals must be determined. A traditional neutralisation test usually takes two to three days and must be carried out with infectious ...
