A burst of "synchronous" light
Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This discovery could enable future developments in LED lighting, quantum sensing, quantum communication and future quantum computing.

A fine-tuned laser welds more effectively
Using laser technology Empa scientists optimized a technique to weld the electronics of implantable pacemakers and defibrillators into a titanium case. The medtech company Medtronic is now using the method worldwide to produce these devices. In Tolochenaz (Canton of Vaud) the US medtech company Medtronic produces one out of five heart pacemakers available on the global market and one out of four defibrillators.

What does graphene do in our lungs?
What does graphene do in our lungs?
Graphene has been hailed as the material of the future. As yet, however, little is known about whether and how graphene affects our health if it gets into the body. A team of researchers from Empa and the Adolphe Merkle Institute (AMI) in Fribourg have now conducted the first studies on a three-dimensional lung model to examine the behavior of graphene and graphene-like materials once they have been inhaled.

This time, it’s all bio: SwissFEL makes protein structures visible
Successful pilot experiment on biomolecules at the newest large research facility of PSI For the development of new medicinal agents, accurate knowledge of biological processes in the body is a prerequisite. Here proteins play a crucial role. At the Paul Scherrer Institute PSI, the X-ray free-electron laser SwissFEL has now, for the first time, directed its strong light onto protein crystals and made their structures visible.

Metal leads to the desired configuration
Metal leads to the desired configuration
Scientists at the University of Basel have found a way to change the spatial arrangement of bipyridine molecules on a surface. These potential components of dye-sensitized solar cells form complexes with metals and thereby alter their chemical conformation. The results of this interdisciplinary collaboration between chemists and physicists from Basel were recently published in the scientific journal ACS Omega.

Why does concrete swell and crack?
Why does concrete swell and crack?
When bridges, dam walls and concrete foundations form cracks, AAR is often the culprit: the alkali-aggregate reaction. It causes the concrete to swell and renders renovations or even reconstructions necessary. A project funded by the Swiss National Science Foundation (SNSF) and coordinated by Empa is studying the "concrete disease".

New tool helps scientists better target the search for alien life
An EPFL scientist has developed a novel approach that boosts the chances of finding extraterrestrial intelligence in our galaxy. His method uses probability theory to calculate the possibility of detecting an extraterrestrial signal (if there is one) at a given distance from Earth.

Microresonators offer a simpler approach to sensing with light pulses
Researchers at EPFL have found a way to implement an optical sensing system by using spatial multiplexing, a technique originally developed in optical-fiber communication. The method, which produces three independent streams of ultrashort optical pulses using a single continuous-wave laser and a single optical microresonator, is far simpler than existing technologies.

Eco-Friendly Nanoparticles for Artificial Photosynthesis
Quantum dots are true all-rounders. These material structures, which are only a few nanometers in size, display a similar behavior to that of molecules or atoms, and their form, size and number of electrons can be modulated systematically. This means that their electrical and optical characteristics can be customized for a number of target areas, such as new display technologies, biomedical applications as well as photovoltaics and photocatalysis.

Marine heatwaves are threatening ecosystems
Marine heatwaves can irreversibly damage ecosystems and, therefore, also present a threat to fishing. As a team led by physicist Thomas Frölicher from Bern showed in a study just published , the number of marine heatwaves has increased dramatically in past decades. This trend will further intensify as a result of climate change.

Signposts for cells
For the replacement of animal testing with alternatives in medical rsearch, complex microtissues need to be cultivated. Researchers from Empa have developed a special polymer scaffold for threedimensional cell cultures. Light beams act as signposts for the cells. In pharmaceutical research, scientists try to do without animal testing wherever possible or replace it with experiments on cell or tissue cultures.
