How tiny droplets can deform ice
When water freezes slowly, the location where water turns into ice - known as the freezing front - forms a straight line. Researchers from the University of Twente showed how droplets that interact with such a freezing front, cause surprising deformations of this front. These new insights were published in a publication in the scientific journal Physical Review Letters and show potential for applications in cryopreservation and food engineering techniques.

Disorder improves battery life
What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team led by TU Delft has discovered that local disorder in the oxide cathode material increases the number of times Li-ion batteries can be charged and discharged. Their results have been published in Nature .

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.

Optimisation of hard-soft material interfaces: A 3D printed imitation of bone-tendon connections
Most people can relate to having a laptop charger break right where the flexible cable meets the solid adapter. This is just one example of how difficult it is to effectively interface hard and soft materials. Using a unique 3D printing process, TU Delft researchers produced hybrid multi-material interfaces that reached a remarkable closeness to nature's design of bone-tendon connections.

Creating efficient transparent p-type conductors
Transparent conductors are essential for many devices, such as touch screens and solar cells. Copper iodide (CuI) can conduct electricity while staying see-through but is not as good as some other materials. Researchers from the University of Twente managed to improve the conductivity of CuI while keeping 75% of its transparency.

Nano droplets go skiing at high temperatures
Currently, many (nano)structures are grown in layers, one above the other, but their ordering on the atomic scale is generally far from perfect. The researchers aim for a better understanding of these processes that can eventually lead to smaller, faster and overall better nanotechnology and have, in a worldwide first observation, discovered pre-solidification in droplet mixture.
