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.

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
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.

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?
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).

Utrecht chemists discover mechanism to design more sustainable molecular catalysts
Utrecht scientists, under the supervision of Marc-Etienne Moret, have discovered a new mechanism to build molecular catalysts. The new mechanism involves the earth-abundant metal nickel instead of precious metals that are often used as part of molecular catalysts. Moret: "This discovery initiates a new area of research that brings about a whole new concept for the design of more sustainable catalysts." In 2017, chemistry researcher Marc-Etienne Moret received an ERC Starting Grant áto study new catalysts with better properties.

Rembrandt broke new ground with lead-based impregnation of canvas for The Night Watch
New research has revealed that Rembrandt impregnated the canvas for his famous 1642 militia painting 'The Night Watch' with a lead-containing substance even before applying the first ground layer. Such lead-based impregnation has never before been observed with Rembrandt or his contemporaries. The discovery , published today in Science Advances, underlines Rembrandt's inventive way of working, in which he did not shy away from using new techniques.
