The holy grail of nanowire production
The holy grail of nanowire production
EPFL researchers have found a way to control and standardize the production of nanowires on silicon surfaces. This discovery could make it possible to grow nanowires on electronic platforms, with potential applications including the integration of nanolasers into electronic chips and improved energy conversion in solar panels.

A transformer to drive the transition from AC to DC
A transformer to drive the transition from AC to DC
EPFL researchers have developed a compact and efficient medium-frequency transformer. Their device is poised to enhance the flexibility and efficiency of tomorrow's smart grids and DC power distribution networks. An EPFL-made prototype has been thoroughly tested and presented in several tutorials designed for experts from the academic and industrial worlds.

Next-generation optics in just two minutes of cooking time
Next-generation optics in just two minutes of cooking time
One of the key building blocks of flexible photonic circuits and ultra-thin optics are metasurfaces. And EPFL engineers have now discovered a simple way of making these surfaces in just a few minutes - without needing a clean room - using a method already employed in manufacturing. Their findings have just been published.

The physical forces of cells in action
The physical forces of cells in action
Swiss scientists have developed probes designed to reveal the physical forces inside living cells. A world first. The detection of physical forces is one of the most complex challenges facing science. Although Newton's apple has long solved the problem of gravity, imaging the physical forces that act in living cells remains one of the main mysteries of current biology.

Cryo-force spectroscopy reveals the mechanical properties of DNA components
Cryo-force spectroscopy reveals the mechanical properties of DNA components
Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs.

Virtual lens improves X-ray microscopy
Virtual lens improves X-ray microscopy
PSI researchers are first to transfer state-of-the-art microscopy method to X-ray imaging X-rays provide unique insights into the interior of materials, tissues, and cells. Researchers at the Paul Scherrer Institute PSI have developed a new method that makes X-ray images even better: The resolution is higher and allows more precise inferences about the properties of materials.

Hand-knitted Molecules
Hand-knitted Molecules
Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips - in a sense as a "hand-knitted" unique specimen. The properties of the molecules can be monitored in real time while they are being produced.

International collaboration publishes concept design for a post-LHC future circular collider at CERN
International collaboration publishes concept design for a post-LHC future circular collider at CERN
Geneva. Today, the Future Circular Collider (FCC) collaboration submitted its Conceptual Design Report (CDR) for publication, a four-volume document that presents the different options for a large circular collider of the future. It showcases the great physics opportunities offered by machines of unprecedented energy and intensity and describes the technical challenges, cost and schedule for realisation.

Measurement of five flashes from the depths of the universe
Measurement of five flashes from the depths of the universe
First-time precise measurement of gamma-ray bursts conducted successfully from a space station A detector called POLAR, developed at PSI, has been sent to outer space to collect data. In September 2016, the device was launched into Earth orbit on board the newest Chinese space station. From that vantage point, POLAR recorded so-called gamma-ray bursts flashing in the far reaches of the universe.

Excitons pave the way to more efficient electronics
Excitons pave the way to more efficient electronics
After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices. They were the first to control exciton flows at room temperature. And now, the team of scientists from EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) has taken their technology one step further.

Pushing the boundaries of the visible
Pushing the boundaries of the visible
Our cutting-edge technology platforms are key enablers of research at the FMI. One of the biggest of these, with the largest number of users, is the Facility for Advanced Imaging and Microscopy (FAIM). To find out more about the facility, and microscopy in general, we spoke to the joint heads of FAIM - Christel Genoud, who is responsible for Electron Microscopy, and Laurent Gelman, responsible for Light Microscopy.
