Ceramics 3D printed from foams
Ceramics 3D printed from foams
ETH researchers have used an additive manufacturing process to print an extremely porous ceramic component. Manufacturing a material of this kind with a 3D printer is a considerable achievement. Doctoral student Carla Minas, from the Complex Materials group led by ETH Professor André Studart, has succeeded in creating a highly porous and yet extremely robust ceramic material, which she ‘printed' using an additive manufacturing process.

Quantum-dot solar windows evolve with 'doctor-blade' spreading
Quantum-dot solar windows evolve with ’doctor-blade’ spreading
A Los Alamos National Laboratory research team demonstrates an important step in taking quantum dot, solar-powered windows from the laboratory to the construction site. "We are developing solar concentrators that will harvest sunlight from building windows and turn it into electricity, using quantum-dot based luminescent solar concentrators," said lead scientist Victor Klimov.

Creating 3D objects from inextensible sheet materials
Creating 3D objects from inextensible sheet materials
Researchers have developed an algorithm for creating complex objects by cutting holes in sheets of inextensible, but flexible materials such as metal, plastic and leather. It has potential applications in many areas, including microengineering, bioengineering, fashion and architecture. EPFL researchers, in collaboration with Carnegie Mellon University and the University of Hull, have come up with a method for creating everyday objects - like a mask or a shoe - from sheets of inextensible material.

TU Graz develops environmentally friendly eco-concrete
TU Graz develops environmentally friendly eco-concrete
Grey on the outside, green inside: The production of "Öko˛-Beton" concrete consumes up to 30 percent less CO2 than the production of standard concrete, and yet the "green" concrete is by no means less stable or less convenient to process.

Physicists Couple Distant Nuclear Spins Using a Single Electron
Physicists Couple Distant Nuclear Spins Using a Single Electron
For the first time, researchers at the University of Basel have coupled the nuclear spins of distant atoms using just a single electron. Three research groups from the Department of Physics took part in this complex experiment, the results of which have now been published Nanotechnology. In most materials, the nuclear spins of neighboring atoms have only a very weak effect on one another, as the tiny nuclei are located deep within the atoms.

Nature knows how to do it - as does
As part of the "LightChEC" research project at the University of Zurich, Empa scientists are working with other researchers on a novel method of artificial photosynthesis - photocatalysis, which uses a purely chemical process to split water into hydrogen and oxygen. Unlike other methods, it does not involve the electrolysis of water.

Cooling, time in the dark preserve perovskite solar power
A new study has found both the cause and a solution for the pesky tendency of perovskite solar cells to degrade in sunlight. 'What we found in this study is that under constant 1-sun illumination the large-grain perovskite solar cells degrade majorly in terms of the photocurrent,' Nie said.

How nanoparticles flow through the environment
How nanoparticles flow through the environment
Carbon nanotubes remain attached to materials for years while titanium dioxide and nanozinc are rapidly washed out of cosmetics and accumulate in the ground. Researchers from the National Research Programme 'Opportunities and Risks of Nanomaterials' (NRP 64) have developed a new model to track the flow of the most important nanomaterials in the environment.

Cycling helmets with optimum ventilation
Cycling helmets with optimum ventilation
Any cyclist who wears a helmet knows the feeling: heat builds up under your helmet and the sweat starts to flow, especially in summer. As a result, many cyclists will take a risk and not even wear a helmet. A research team at Empa has now studied the flow of heat under cycling helmets in detail - the first step towards "sweat-free" protective headgear.
