- Catalyst surface analysed at atomic resolution
Catalyst surfaces have rarely been imaged in such detail before. And yet, every single atom can play a decisive role in catalytic activity. A German-Chinese research team has visualised the three-d... - Unexpected energy storage capability where water meets metal surfaces
A new method can measure the electrical (re-)charging of boundary layers between very small, metallic particles and aqueous solutions and understand it at a molecular level. Researchers from the... - A sieve for molecules
Scientists have long tried to use graphene, which is composed of carbon, as a kind of sieve. But this material doesn't have any pores. Now, a team has found an alternative material which comes with... - Deep insights into a living fungus
Light sheet microscopy enables us to examine fungal fruiting bodies on a living object. In order to examine tissues under the microscope, they usually have to be cut into thin slices. But it is ... - Copper is effective against SARS-CoV-2 on surfaces - silver is not
Copper and silver are known for their antibacterial properties. Researchers from Bochum have explored their effectiveness against viruses. Silver and copper ions wipe out many pathogens. That's why... - Novel sensors enable precise measurement of dopamine
Carbon nanotubes glow brighter in the presence of neurotransmitters. This facilitates the easy and accurate measurement of signals between nerve cells. Dopamine is an important signalling molecu... - How artificial intelligence can explain its decisions
Today, when an algorithm identifies a tumour in a tissue sample, it doesn't reveal how it arrived at this result. And that's not very trustworthy. Researchers in Bochum are therefore pursuing a new...
- Plasmas as chemistry labs
The smaller a plasma, the larger the experimental setup needed to study it. It is worth the effort, because the reaction conditions found in cubic-millimetre-sized plasmas are very much unique. ... - How Confined Protons Migrate
Protons in aqueous solution can usually migrate very quickly - much faster compared to other ions. However, this only applies when they are in a space greater than two nanometers, as a study from R...
- Insights into the structure of an enigmatic catalyst
In the past, the catalyst for the production of methanol had eluded all attempts to clarify its surface structure. Now researchers have learned more about its active site. Methanol is one of the... - Programmable synthetic materials
In DNA, information is stored in the sequence of chemical building blocks; in computers, information consists of sequences of zeros and ones. Researchers want to transfer this concept to artificial...
- Structure and function of photosynthesis protein explained in detail
An international team of researchers has solved the structure and elucidated the function of photosynthetic complex I. This membrane protein complex plays a major role in dynamically rewiring photo... - Converting biomass by applying mechanical force
One of the greatest global challenges is the efficient use of renewable sources in order to meet the increasing demand for energy and feedstock chemicals in the future. In this context, biomass is ... - Improving the lifetime of bioelectrodes
The use of proteins involved in the photosynthetic process enables the development of affordable and efficient devices for energy conversion. However, although proteins such as photosystem I are ro... - Carbon nanoelectrode - Particle at the stick
Since they are so tiny, it is difficult to investigate single nanoparticles. However, this is exactly what researchers are aiming for in order to tailor their properties. A novel approach: particle... - Catalysis: High reaction rates even without precious metals
Precious metals are often efficient catalysts. But they are expensive and rare. However, it has so far been difficult to determine how efficient non-precious metal alternatives are. Non-precious...
- Carbon dioxide as a raw material
Researchers at the Ruhr-Universität Bochum have found a way to turn climate-damaging CO2 into an alcohol that could serve as a raw material for the chemical industry - without producing large amoun... - Individual silver nanoparticles observed in real time
The particles have an antibacterial and anti-inflammatory effect. They are used in medicine and the food industry. But little is known about their mode of action and degradation so far. Chemists... - Bio solar cell produces hydrogen
An international team of researchers has combined molecular building blocks from plants and microorganisms in a bio solar cell so that they could use light energy to directly produce hydrogen. This...
- New insights into the supercritical state of water
Using molecular dynamics simulations, researchers have analysed the properties of supercritical water. The researchers showed which structure of the hydrogen bond network is formed in different sup... - New electrode for ion concentration analysis does not require electrolyte solution
For the purpose of blood analyses and industrial tests, it is often necessary to measure the concentration of specific ions. At present, the relevant devices are large and cannot be produced at low... - Folding molecules into screw-shaped structures
Artificial molecules are like sheets of paper. Chemists can fold them into specific shapes. Transferring the shape of one molecule to another, however, poses a significant challenge. An internat... - New approach for a Hydrogen production process suited for industrial applications
Hydrogen is considered as a potential energy carrier of the future. However, its mass production remains problematic. Bochum-based researchers have found a new approach for a process suited for ind... - How water gets its exceptional properties - New simulation method
Water is liquid at room temperature - astounding for such a small molecule. Insights into the causes are provided by a new simulation method, which has its origins in brain research. Using artif... - New catalyst for hydrogen production
With the aid of platinum catalysts, it is possible to efficiently produce hydrogen. However, this metal is rare and expensive. Researchers have discovered an alternative that is just as good, but l...
