New method for using spin waves in magnetic materials
New method for using spin waves in magnetic materials
Smaller, faster, more energy-efficient - this is the goal that developers of electronic devices have been working towards for years. In order to be able to miniaturize individual components of mobile phones or computers for example, magnetic waves are currently regarded as promising alternatives to conventional data transmission functioning by means of electric currents.

A "simulation booster" for nanoelectronics
Two research groups from ETH Zurich have developed a method that can simulate nanoelectronics devices and their properties realistically, quickly and efficiently. This offers a ray of hope for the industry and data centre operators alike, both of which are struggling with the (over)heating that comes with increasingly small and powerful transistors.

Experiment to increase understanding of the universe secures £30m
UCL scientists working to understand neutrinos and antimatter through DUNE (the Deep Underground Neutrino Experiment) will benefit from the UK's latest multi-million pound investment in the project. The DUNE project brings together more than 1,000 physicists from the UK and 31 countries from Asia, Europe and the Americas to build the world's most advanced neutrino observatory, which could lead to profound changes in our understanding of the universe.

Cosmic explosions: detecting the highest-energy light
The most energetic form of light has been detected from a distant but powerful cosmic explosion known as a 'gamma-ray burst' for the first time, by an international team including UCL physicists using a UCL-built space telescope onboard NASA's Neil Gehrels Swift Observatory. The discovery and in particular, the unknown mechanisms that cause extremely high-energy light to be emitted in the afterglow of a gamma-ray burst (GRB).

The Beauty of Imperfections: Linking Atomic Defects to 2D Materials’ Electronic Properties
Scientists at Berkeley Lab reveal oxygen's hidden talent for filling in atomic gaps in TMDs; and the surprising role of electron spin in conductivity Like any material, atomically thin, 2D semiconductors known as TMDs or transition metal dichalcogenides are not perfect, but their imperfections can actually be a good thing.

Stabilizing a cliff using biomineral binders
Stabilizing a cliff using biomineral binders
EPFL spin-off Medusoil has successfully tested its ground-stabilization process on cliffs subject to surface erosion. The company's biomineral-based solution can be used to stabilize sandy and gravelly subsoils to safeguard surrounding infrastructure. It is a long-lasting and easy-to-use alternative to industrial fluids - the production and use of which can be harmful to the environment.

A Remote Control for Everything Small
A Remote Control for Everything Small
Atoms, molecules or even living cells can be manipulated with light beams. At TU Wien a method was developed to revolutionize such "optical tweezers". They are reminiscent of the "tractor beam" in Star Trek: special light beams can be used to manipulate molecules or small biological particles. Even viruses or cells can be captured or moved.

A super-fast
A super-fast "light switch" for future cars and computers
Switching light beams quickly is important in many technological applications. Researchers at ETH have now developed an "electro-opto-mechanical" switch for light beams that is considerably smaller and faster than current models. This is relevant for applications such as self-driving cars and optical quantum technologies.

Ask a five-year-old, and you might hear 'teenage." A mid-lifer might say '80." To University of Wisconsin-Madison professor of geosciences John Valley, age 71, "old" is 4-billion years plus.

New Material Breaks World Record Turning Heat into Electricity
New Material Breaks World Record Turning Heat into Electricity
A new type of material generates electrical current very efficiently from temperature differences. This allows sensors and small processors to supply themselves with energy wirelessly. Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: If there is a temperature difference between the two ends of such a material, electrical voltage can be generated and current can start to flow.

Observing changes in the chirality of molecules in real time
Chiral molecules - compounds that are mirror images of each other - play an important role in biological processes and in chemical synthesis. Chemists at ETH Zurich have now succeeded for the first time in using ultrafast laser pulses to observe changes in chirality during a chemical reaction in real time.

New synthesis approach for soluble silicon clusters
New synthesis approach for soluble silicon clusters
Theoretical calculations indicate that under certain conditions silicon can endow solar cells with a much higher efficiency. Small silicon clusters may provide a source of accordingly modified silicon. However, to date these clusters have not been accessible in soluble form, a prerequisite for flexible processing.

Magnets for the second dimension
Magnets for the second dimension
ETH scientists have developed cube-shaped magnetic building blocks that can be assembled into two-dimensional shapes and controlled by an external magnetic field. They can be used for soft robotics applications. If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it.

Invention of teeny-tiny organic films could enable new electronics
The first cell phone, released in 1983, was the size of a brick and weighed two-and-a-half pounds. The newest Apple Watch, released this fall, weighs 1.1 ounces. These kind of technological leaps have been made possible by finding new and inventive ways of combining materials, which can pack more information and circuitry into smaller and smaller packages.

Team uses golden ’lollipop’ to observe elusive interference effect at the nanoscale
Electrons in atoms are pretty talented. They can form chemical bonds, get kicked out of the atom and even "jump" to different locations based on their energetic states. In 1961, atomic physicist Ugo Fano theorized that electrons harbor another and unexpected talent: They can interfere with themselves as they simultaneously take two different quantum-mechanical paths.
