Scientists at the Max Planck Institute for Polymer Research (MPI-P) led by Dr. Kamal Asadi have solved a four decade long challenge of producing very thin nylon films that can be used for instance in electronic memory components. The thin nylon films are several 100 times thinner than human hair and could thus be attractive for applications in bendable electronic devices or for electronics in clothing.
The 'Landau-level laser' is an exciting concept for an unusual radiation source. It has the potential to efficiently generate terahertz waves, which can be used to penetrate materials as well as for future data transmission. So far, however, nearly all attempts to make such a laser have failed. An international team has now taken an important step in the right direction: In the journal Nature Photonics, they describe a material that generates terahertz waves by simply applying an electric current.
Researchers from the Egyptian Museum and Papyrus Collection, Berlin universities and Helmholtz-Zentrum Berlin studied a small piece of papyrus that was excavated on the island of Elephantine on the River Nile a little over 100 years ago. The team used serval methods including non-destructive techniques at BESSY II. The researchers' work, reported in the Journal of Cultural Heritage, blazes a trail for further analyses of the papyrus collection in Berlin.
The quantum Hall effect (QHE), which was previously known for two-dimensional (2D) systems, was predicted to be possible for three-dimensional (3D) systems by Bertrand Halperin in 1987, but the theory was not proven until recently by researchers from the Singapore University of Technology and Design (SUTD) and their research collaborators from around the globe.
Machine learning algorithms can sometimes do a better job with a little help from human expertise, at least in the field of materials science.
A group of researchers from UCPH FOOD have figured out how to use deep learning to speed up the analysis of gas chromatographic data. Because this type of analysis is used in many parts of society, the new method will have a major impact on quality, efficiency and cost when examining various data -- from blood tests, to the fermentation of cheese.
A group of researchers led by Skoltech Professor Pavel Troshin studied coordination polymers, a class of compounds with scarcely explored applications in metal-ion batteries, and demonstrated their possible future use in energy storage devices with a high charging/discharging rate and stability. The results of their study were published in the journal Chemistry of Materials.
Jiaxing Huang's counterintuitive discovery will help engineers make stronger materials.
Newly discovered properties in the compound uranium ditelluride show that it could prove highly resistant to one of the nemeses of quantum computer development -- the difficulty with making such a computer's memory storage switches, called qubits, function long enough to finish a computation before losing the delicate physical relationship that allows them to operate as a group. This relationship, called quantum coherence, is hard to maintain because of disturbances from the surrounding world.
An innovative way to pattern metals has been discovered by scientists in the Department of Chemistry at the University of Warwick, which could make the next generation of solar panels more sustainable and cheaper.
