Can a computer chip have zero energy loss in 1.58 dimensions?
Can a computer chip have zero energy loss in 1.58 dimensions?
What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and three (cube) dimensions; all with different possible applications in electronic devices.

A route to scalable Majorana qubits
A route to scalable Majorana qubits
Researchers at QuTech have found a way to make Majorana particles in a two-dimensional plane. This was achieved by creating devices that exploit the combined material properties of superconductors and semiconductors. The inherent flexibility of this new 2D platform should allow one to perform experiments with Majoranas that were previously inaccessible.

Meike Bos investigated how lungs transport mucus by using physics
Applying physics to better understand complicated biological processes: that is what Meike Bos did during her PhD. She used computer models to investigate how ciliated cells in the airways move to ensure that mucus can be transported. Her research, culminating in a successful dissertation defense on 29 May, highlights the power of computational modeling in addressing complex biological phenomena.

Strings that can vibrate forever (kind of)
Strings that can vibrate forever (kind of)
Researchers from TU Delft and Brown University have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object - approaching what is currently only achievable near absolute zero temperatures. Their study, published in Nature Communications , pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.

Nanobubble research to improve green hydrogen production
Nanobubble research to improve green hydrogen production
In a novel study , researchers of the University of Twente have made significant strides in understanding the behaviour of microand nanobubbles on electrodes during water electrolysis. This process is crucial for (green) hydrogen production. These tiny bubbles form on the electrodes, blocking the flow of electricity and reducing the efficiency of the reaction.

A nanophotonic fiber-tip solution to detect the ultrasmall
A nanophotonic fiber-tip solution to detect the ultrasmall
Using an ultrasensitive photonic crystal, TU/e researchers were able to detect single particles down to 50 nanometers in diameter. The new research has just been published in the journal Optica. What do volcanic lava, fire smoke, automobile exhaust fumes, and printer toner have in common? They are all sources of ultrafine particles - particles with a diameter below 100 nanometers, which can pose serious health risks if inhaled.

Magnetism boosts hydrogen production in model catalysts
Researchers at the University of Twente have shown how to improve the efficiency of hydrogen production in an experimental setup. They showed that the magnetic order of the molecules plays a critical role. In the search for green hydrogen, the design of efficient catalyst materials that increase the efficiency and speed of the chemical reaction that produces (green) hydrogen is essential.

The energy transition under the nanoscope: Gravitation funding for ANION
Bringing together chemists and physicists to thoroughly investigate how electrochemical processes work on the smallest scale. That is the goal of the new Advanced Nano-electrochemistry Institute of the Netherlands, or ANION for short. The consortium receives a Gravitation funding of 23.6 million euros for this purpose.

Synthetic material sheds new light on how liquids separate
Synthetic material sheds new light on how liquids separate
Hailin Fu found the chemical system that behaves like cell organelles with well-defined segregated areas in a water-based solution by accident. She followed the science to the end though, and she describes her and her colleagues' journey of discovery in a new paper just published in Nature. It is quite rare to see a Nature article, with all'authors on the paper coming from the same institute.

What did the electron ’say’ to the phonon in the graphene sandwich?
A TU/e and Catalan Institute of Nanoscience and Nanotechnology-led collaboration involving researchers from around the world has the answer, and the why, and the results have just been published in the journal Science Advances. Electrons carry electrical energy, while vibrational energy is carried by phonons.

M87* one year later: proof of persistent black hole shadow
The brightness peak of the ring around M87's supermassive black hole has shifted 30 degrees counterclockwise in a year. This is shown in new images released by the Event Horizon Telescope Collaboration. The Event Horizon Telescope (EHT) Collaboration , with contributions by Dutch astronomers, has released new images of M87*, the supermassive black hole at the center of the galaxy Messier 87, using data from observations taken in April 2018.

Nanoscale friction investigated to reduce energy losses in future industry
Friction is responsible for nearly a quarter of all irreversible energy losses in the modern world's industry. That is why scientists worldwide are trying to find better ways to reduce these losses. An international group of authors including Igor Ostanin, Assistant Professor at the department of Engineering Technology, University of Twente, investigated the fundamental question of dynamic mechanisms of structural superlubricity (a vanishingly small friction, observed between the two molecularly smooth surfaces).
