Steering molecular twisting for hydrogen generation
Steering molecular twisting for hydrogen generation
Researchers from the Faculty of S&T at the University of Twente have shown a novel approach for the design of efficient solar fuel devices. Research performed by graduated PhD candidate Kaijian Zhu shows that reducing the light-induced twisting of molecules can turn hydrogen generation on. Photoelectrochemical cells are promising for the production of solar fuels, for example, the conversion of water into hydrogen or CO2 into organic molecules.

Solving a memristor mystery to develop efficient, long-lasting memory devices
Newly discovered role of phase separation can help develop memory devices for energy-efficient AI computing Study: Thermodynamic origin of nonvolatility in resistive memory (DOI: 10.1016/j.matt. Phase separation, when molecules part like oil and water, works alongside oxygen diffusion to help memristors-electrical components that store information using electrical resistance-retain information even after the power is shut off, according to a University of Michigan led study recently published in Matter.

Electrically Modulated Light Antenna Points the Way to Faster Computer Chips
Physicists from Würzburg present a nanometre-sized light antenna with electrically modulated surface properties - a breakthrough that could pave the way for faster computer chips. Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz - which corresponds to several billion computing operations per second.

The counter-intuitive statistics of thermodynamics on a microscopic scale
Publication of the Physics Laboratory in the Physical Review Letters on July 31, 2024. Communication by CNRS Physics on September 2, 2024. Experiments on a classical microscopic system show that, while the second principle of thermodynamics is still valid on average, it can be circumvented experimentally in 95% of cases! A study conducted at the Physics Laboratory of ENS de Lyon, published in Physical Review Letters .

Crystallised alternative DNA structure sheds light on insulin and diabetes
Crystallised alternative DNA structure sheds light on insulin and diabetes
The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one another, known as a double helix, but it is possible for DNA to change shape and structure. The new study, published in Nature Communications , reveals the detail in the structure of a type of DNA called i-motif, by crystallising it for the first time.

Being able to see inside a flow battery
Being able to see inside a flow battery
Using neutrons, TU/e scientists visualize the internal processes of a redox flow battery. At the beginning of the 20th century, the invention of X-ray imaging provided a leap of knowledge in medical science. Since then, we can see how our body's bones work, bringing numerous new treatments to light. Now, a similar approach using neutron imaging makes it possible to visualize the internal functioning of redox flow batteries - a type of battery mainly used for large-scale storage in solar and wind energy systems.

Energy storage mechanism in the thinnest possible lithium-ion battery
A team of scientists from the University of Manchester has achieved a significant breakthrough in understanding lithium-ion storage within the thinnest possible battery anode - composed of just two layers of carbon atoms. Their research, published in Nature Communications , shows an unexpected 'in-plane staging' process during lithium intercalation in bilayer graphene, which could pave the way for advancements in energy storage technologies.

VUB astrophysicist investigates noise in gravitational waves to unravel the universe's earliest phases
VUB astrophysicist investigates noise in gravitational waves to unravel the universe’s earliest phases
Gravitational waves are ripples in spacetime. The phenomenon can be compared to ripples on a sheet when a heavy ball is placed on it and spun around. In the universe, these "balls" are massive objects such as black holes and neutron stars, which vibrate spacetime as they orbit and eventually merge. These gravitational waves are emitted through space and, although very subtle, can be detected on Earth with the correct equipment.

One-way street for sound waves
One-way street for sound waves
Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that person can hear us as well as we can hear them.

Atoms on the edge
Atoms on the edge
Physicists capture images of ultracold atoms flowing freely, without friction, in an exotic "edge state." Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls.

Nanostructures enable on-chip lightwave-electronic frequency mixer
Lightwave electronics aim to integrate optical and electronic systems at incredibly high speeds, leveraging the ultrafast oscillations of light fields. Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end.
