The photoelectric effect in stereo

“In the photoelectric effect, a photon ejects an electron from a material. Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location …

Protecting plants intelligently

“We must reduce the environmental and health risks of pesticides. However, rather than banning them completely, Robert Finger advocates an intelligent approach to crop protection. Glyphosate, neonicotinoids, drinking water initiative – renouncing pesticides is currently the subject of fierce discussion. For …

Quantum transfer at the push of a button

“In the new quantum information technologies, fragile quantum states have to be transferred between distant quantum bits. Researchers at ETH have now realized such a quantum transmission between two solid-state qubits at the push of a button. Data transmission is …

Swimming without an engine

“Using nothing but 3D printing, scientists have developed a paddling submarine that requires no engine, propellant or power supply. Researchers at ETH Zurich under the direction of ETH Professor Kristina Shea and colleagues at Caltech in Pasadena, California, have developed …

Valves for tiny particles

“Newly-developed nanovalves allow the flow of individual nanoparticles in liquids to be controlled in tiny channels. This is of interest for lab-on-a-chip applications such as in materials science and biomedicine. Researchers from ETH Zurich have developed tiny valves that enable …

An electronic rescue dog

“ETH Zurich scientists have developed the smallest and cheapest ever equipment for detecting people by smell. It could be used in the search for people buried by an earthquake or avalanche. Trained rescue dogs are still the best disaster workers …

Further confirmation of quantum mechanics

“Nowadays, it is accepted among physicists that Albert Einstein was wrong in his scepticism of quantum mechanics. This was also confirmed by the Big Bell Test involving over 100,000 people around the world in November 2016. Quantum physics is …

New materials for sustainable, low-cost batteries

“A new conductor material and a new electrode material could pave the way for inexpensive batteries and therefore the large-scale storage of renewable energies. The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable …

The thermodynamics of computing

“Information processing requires a lot of energy. Energy-saving computer systems could make computing more efficient, but the efficiency of these systems can’t be increased indefinitely, as ETH physicists show. As steam engines became increasingly widespread in the 19th century …

Robotic collaboration in timber construction

“Researchers from ETH Zurich are using a new method for digital timber construction in a real project for the first time. The load-bearing timber modules, which are prefabricated by robots, will be assembled on the top two floors at the …
