Let information flow faster - with light instead of electricity
Either 1 or 0. Either current flows or it does not. In electronics, everything is controlled via the binary system. Electrons already generate information quite fast and well, pass them on and take over various switching functions. But it can be done even faster. Paul Herrmann and Sebastian Klimmer from the Friedrich Schiller University of Jena have proven that.

ToCoTronics Extended
The Collaborative Research Centre ToCoTronics in condensed matter physics will be extended for four more years. The German Research Foundation is funding it with 12 million euros. Topological materials are intensively investigated in the world. This boom started at Julius-Maximilians-Universität (JMU) Würzburg, where the physics professor Laurens Molenkamp realized the first topological insulator in 2007.

Specially coated titanium reduces risk of clots on prostheses
Around 25,000 artificial heart valves are implanted  in Germany per year because the original heart valve is damaged, for example, by an infection. The mechanical heart valves are made of titanium dioxide, among other materials, and last for many years. However, because blood tends to clot on contact with these material surfaces, there is a risk of blood clots forming on the surface of mechanical heart valves.

3D printing to strengthen a key material in aerospace, energy-generation applications
The approach could improve the performance of many other materials as well. The materials key to many important applications in aerospace and energy generation must be able to withstand extreme conditions such as high temperatures and tensile stresses without failing. Now a team of MIT-led engineers reports a simple, inexpensive way to strengthen one of the key materials used today in such applications.

New glass from the computer
Glass is a very special material: it can be produced in almost unlimited variety from compounds of almost all elements of the periodic table. The only prerequisite is that the components can be melted together and that the melt is then cooled quickly enough. In the process, the liquid mixture solidifies and forms a glass.

Sustainable solar cell material shown to be highly promising for medical imaging
Using X-rays to see inside the human body has revolutionised non-invasive medical diagnostics. However, the dose of X-rays required for imaging is far higher than background levels, due to the poor performance of the detector materials currently available. This can cause harm to patients, and in some cases even cancer.

Closer to next-generation electronics
EPFL engineers have found a way to control the interactions between excitons - quasiparticles that may one day transport data and replace the electrons in electronic devices. The engineers' method involves applying an electric field to a two-dimensional (2D) semiconducting material. Electronic devices have become an essential feature of just about all aspects of modern society.

More power from waste heat
When fossil fuels, but also biofuels, are burned, large amounts of the energy are lost as waste heat. Thermoelectric materials could convert this heat into electricity, but they are not yet efficient enough for technical application. A team from the Max Planck Institut für Eisenforschung has now increased the efficiency of a thermoelectric material by elucidating the influence of the microstructure on the material and optimizing the material's properties by adding titanium.

Deep-learning system explores materials’ interiors from the outside
A new method could provide detailed information about internal structures, voids, and cracks, based solely on data about exterior conditions. Maybe you can't tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an airplane part to a medical implant.
