Printing complex cellulose-based objects
Printing complex cellulose-based objects
Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-based parts. To achieve this, they used a clever trick.

Puzzle about nitrogen solved thanks to cometary analogues
Puzzle about nitrogen solved thanks to cometary analogues
One of the basic building blocks of life is nitrogen. An international consortium was able to detect ammonium salt containing nitrogen on the cometary surface of Chury thanks to a method using analogues for comet material. The method on which the study on the detection of ammonium salt is based was developed at the University of Bern.

Nano-sponge with extreme properties
Nano-sponge with extreme properties
A new process simplifies the fabrication of porous materials with a defined nanostructure and takes them one step closer to mass production. Materials with a defined nanostructure can have surprising properties. One example is a lightweight ceramic that springs back to its original shape, like a sponge, after being compressed.

Short film of a magnetic nano-vortex
Short film of a magnetic nano-vortex
For the first time, researchers at the Paul Scherrer Institute PSI have recorded a "3D film" of magnetic processes on the nanometer scale. This reveals a variety of dynamics inside the material, including the motion of swirling boundaries between different magnetic domains. The insights were gained with a method newly developed at the Swiss Light Source SLS.

Creating custom light using 2D materials
Creating custom light using 2D materials
Researchers from the University of Geneva and the University of Manchester have discovered structures based on two-dimensional materials that emit tailor-made light in any colour you could wish for. Finding new semi-conductor materials that emit light is essential for developing a wide range of electronic devices.

Our memory prefers essence over form
Our memory prefers essence over form
Researchers from the University of Geneva and CY Cergy Paris University have shown that current situations conjure up past situations that share deep, structural, similarities. What clues does our memory use to connect a current situation to a situation from the past? The results of a study conducted by researchers from the University of Geneva , Switzerland, - working in collaboration with CY Cergy Paris University in France - contrast sharply with the explanations found until now in the existing literature.

A fast light detector made of two-dimensional materials
A fast light detector made of two-dimensional materials
Two research groups at ETH Zurich have joined forces to develop a novel light detector. It consists of two-dimensional layers of different materials that are coupled to a silicon optical waveguide. In the future, this approach can also be used to make LEDs and optical modulators. Fast and highly efficient modulators as well as detectors for light are the core components of data transmission through fibre optic cables.

New quasiparticle unveiled in room temperature semiconductors
New quasiparticle unveiled in room temperature semiconductors
Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites. The optical properties of semiconductors are governed by the so-called 'excitons', which are bound pairs of negative electrons and positive holes.

A novel formulation to explain heat propagation
A novel formulation to explain heat propagation
Researchers at EPFL and MARVEL have developed a novel formulation that describes how heat spreads within crystalline materials. This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent.

Harnessing the moiré effect to make transparent images
Researchers at EPFL have developed a material that combines transparent properties with the moiré effect to produce images. The technology could have interesting decorative and anti-forgery applications. Applying a moiré pattern to a transparent material is a new and surprising way of creating images.

An 18-carat gold nugget made of plastic
An 18-carat gold nugget made of plastic
ETH researchers have created an incredibly lightweight 18-carat gold, using a matrix of plastic in place of metallic alloy elements. Lovers of gold watches and heavy jewellery will be thrilled. The objects of their desire may someday become much lighter, but without losing any of their glitter. Especially with watches, a small amount of weight can make all the difference.

Bandage material helps stop bleeding without adhering to the wound
Bandage material helps stop bleeding without adhering to the wound
Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot and doesn't stick to the wound. This marks the first time that scientists have combined both properties in one material. "We did not actually plan this, but that is just how science works sometimes: you start researching one thing and end up somewhere else," says ETH Professor Dimos Poulikakos.
