Delft researchers take next step towards better batteries with widely available materials
Delft researchers are developing batteries that can charge faster, offer more stable storage and are made of sustainable materials that are widely available. In doing so, they offer a cheaper alternative to lithium-ion batteries that consist of rare materials and have a high CO2-footprint. A paper was recently published in Nature Energy by Marnix Wagemaker and Alexandros Vasileiadis in collaboration with researchers from the Chinese Academy of Sciences, on fast-charging Na-ion batteries and improvements made to the negative electrode.

Artificial cartilage with the help of 3D printing
Artificial cartilage with the help of 3D printing
A new approach to producing artificial tissue has been developed at TU Wien: Cells are grown in microstructures created in a 3D printer. Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken towards creating replacement tissue in the lab - using a technique that differs significantly from other methods used around the world.

Innovative coating prevents limescale formation
Innovative coating prevents limescale formation
Wherever hot water flows, limescale is never far away. In households, this is a nuisance; in thermal power stations, it's an expensive problem. Now researchers at ETH Zurich have found an answer. Hot water tanks, washing machines, kettles: limescale forms in every domestic appliance that comes into contact with (hot) water - especially in areas where the water is hard, meaning high in calcium.

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.

When nanoplastics are not what they seem
When nanoplastics are not what they seem
Textiles made of synthetic fibers release microand nanoplastics during washing. researchers have now been able to show: Some of the supposed nanoplastics do not actually consist of plastic particles, but of water-insoluble oligomers. The effects they have on humans and the environment are not yet well-understood.

New AI tool discovers realistic ’metamaterials’ with unusual properties
A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue. These extraordinary objects are already made from 'metamaterials'. Researchers from TU Delft have now developed an AI tool that not only can discover such extraordinary materials but also makes them fabrication-ready and durable.

Sound-powered sensors stand to save millions of batteries
Sound-powered sensors stand to save millions of batteries
Researchers at ETH Zurich have developed a sensor that utilises energy from sound waves to control electronic devices. This could one day save millions of batteries. Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power.

Benchtop test quickly identifies extremely impact-resistant materials
Benchtop test quickly identifies extremely impact-resistant materials
High-speed experiments can help identify lightweight, protective "metamaterials" for spacecraft, vehicles, helmets, or other objects. An intricate, honeycomb-like structure of struts and beams could withstand a supersonic impact better than a solid slab of the same material. What's more, the specific structure matters, with some being more resilient to impacts than others.

New Wearable Sensor Accurately Tracks Tiny Changes in the Breath Process
"Our sensor is like a highly accurate microphone for your breath. It can pick up on the tiniest changes in airflow, providing valuable physiological information on an individual, for example related to their cardiac, neurological and pulmonary conditions as well as certain types of illness. " Manchester scientists have developed a new type of wearable sensor that can precisely track your breath, even the slightest changes in the exhaling and inhaling processes.

New model predicts how shoe properties affect a runner's performance
New model predicts how shoe properties affect a runner’s performance
Developed by MIT engineers, the model could be a tool for designers looking to innovate in sneaker design. A good shoe can make a huge difference for runners, from career marathoners to couch-to-5K first-timers. But every runner is unique, and a shoe that works for one might trip up another. Outside of trying on a rack of different designs, there's no quick and easy way to know which shoe best suits a person's particular running style.
