Glass from a 3D printer
Glass from a 3D printer
ETH researchers are using a 3D printing method to produce complex, highly porous glass structures. The technology makes it possible to produce made-to-measure objects that may eventually make life difficult for counterfeiters. Producing glass objects using 3D printing is not easy. Only a few groups of researchers around the world have attempted to produce glass using additive methods.

Observing changes in the chirality of molecules in real time
Chiral molecules - compounds that are mirror images of each other - play an important role in biological processes and in chemical synthesis. Chemists at ETH Zurich have now succeeded for the first time in using ultrafast laser pulses to observe changes in chirality during a chemical reaction in real time.

A cheaper way to scale up atomic layer deposition
A cheaper way to scale up atomic layer deposition
Chemical engineers at EPFL have developed a new method for atomic layer deposition, a technique commonly used in high-quality microelectronics. The new method can be used in materials with larger surfaces much more cheaply than current approaches, while preserving quality and efficiency. Atomic layer deposition (ALD) involves stacking layers of atoms on top of each other like pancakes.

Nitrous oxide emissions set to rise in the Pacific Ocean
Nitrous oxide emissions set to rise in the Pacific Ocean
The acidification of the Pacific Ocean in northern Japan is increasing the natural production rate of N2O, an ozone-depleting greenhouse gas. That's the finding of a study carried out jointly by scientists at EPFL, Tokyo Institute of Technology and Japan Agency for Marine-Earth Science and Technology and appearing recently.

Slow Decay
Slow Decay
"Corrosion" comes from Latin "corrodere": to gnaw something to pieces. This refers to the gradual destruction of a substance due to the influence of other substances in the environment. Specialists at Empa take a close look at such processes and can find timely ways to prevent material failure due to corrosion - long before disasters such as those in Genoa occur.

Healthy organelles, healthy cells
Healthy organelles, healthy cells
It has recently become clear just how important membraneless organelles are for cells. Now biochemists at ETH Zurich have discovered a novel mechanism that regulates the formation of these organelles. This has laid the foundation for more targeted research into diseases such as Alzheimer's or ALS. For a long time, the contents of cells were thought to be fairly unstructured and chaotic: a mixture of proteins, DNA and a multitude of small metabolic molecules.

A battery with a twist
A battery with a twist
Markus Niederberger's team of researchers at ETH has used stretchable materials to develop a battery that can be bent, stretched and twisted. For applications in bendable electronic devices, this is precisely the kind of battery they need. Today's electronics industry is increasingly focusing on computers or smartphones with screens that can be folded or rolled.

A molecular bridge further
A molecular bridge further
Electronics built from molecules could open up new possibilities in the miniaturization of circuits in the future. Empa researchers, together with partners from Switzerland, the Netherlands, Israel, and the UK, succeeded in solving a crucial detail in the realization of such circuit elements: A molecular bridge for electrons that remains mechanically and electronically stable at room temperature.

Measuring ethanol's deadly twin
Measuring ethanol’s deadly twin
ETH researchers have developed an inexpensive, handheld measuring device that can distinguish between methanol and potable alcohol. It offers a simple, quick method of detecting adulterated or contaminated alcoholic beverages and is able to diagnose methanol poisoning in exhaled breath. Methanol is sometimes referred to as ethanol's deadly twin.

Graphene nanoflakes: a new tool for precision medicine
Graphene nanoflakes: a new tool for precision medicine
Chemists funded by the SNSF have created a new compound for flexible drug delivery that specifically targets prostate cancer cells. Incorporating four different molecules, the compound prevents tumour cells from multiplying, can be detected by medical imaging and has staying power in the bloodstream.

A catalyst for sustainable methanol
A catalyst for sustainable methanol
Scientists at ETH Zurich and oil and gas company Total have developed a new catalyst that converts CO2 and hydrogen into methanol. Offering realistic market potential, the technology paves the way for the sustainable production of fuels and chemicals. The global economy still relies on the fossil carbon sources of petroleum, natural gas and coal, not just to produce fuel, but also as a raw material used by the chemical industry to manufacture plastics and countless other chemical compounds.

Adding a polymer stabilizes collapsing metal-organic frameworks
Adding a polymer stabilizes collapsing metal-organic frameworks
Porous metal-organic frameworks (MOFs) have many applications like carbon capture and water-cleaning. However, MOFs with large pores tend to collapse. Chemists and chemical engineers at EPFL have now solved the problem by adding small amounts of a polymer into the MOF pores, an act that impedes pore collapse.

Friedrich Miescher - 150 years of DNA
The Friedrich Miescher Institute for Biomedical Research is a leader in the field of DNA and RNA research. DNA has become the icon of modern bioscience but few people realize that it was our namegiver, who - almost a century before Watson and Crick - laid the chemical groundwork for the molecular breakthroughs that followed.

Molecular energy machine as a movie star
Molecular energy machine as a movie star
Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed a new investigative method that could make the analysis of cellular processes significantly more effective than before.

Carbon-neutral fuels move a step closer
Carbon-neutral fuels move a step closer
Chemists at EPFL have developed an efficient process for converting carbon dioxide into carbon monoxide, a key ingredient of synthetic fuels and materials. The carbon dioxide (CO2) produced when fossil fuels are burned is normally released into the atmosphere. Researchers working on synthetic fuels - also known as carbon-neutral fuels - are exploring ways to capture and recycle that CO2.

Learning from Nature’s Bounty: New Libraries for Drug discovery
Natural products, or their close derivatives, make some of our most potent medicines, among which macrocycles with their large carbon-rich ring systems are one class. The size and complexity of macrocycles has made it difficult to emulate and build on Nature's success in the laboratory.

Floating power plants
Huge floating solar islands on the ocean that produce enough energy to enable CO2-neutral global freight traffic - what sounds like "science fiction" researchers from ETH Zurich, the Paul Scherrer Institute (PSI), Empa, the Universities of Zurich and Bern and the Nowegian University of Science and Technology (NTNU) in Trondheim have now calculated for the first time, as they write in the latest issue of the journal "Proceedings of the National Academy of Sciences" (PNAS).

Exposing modern forgers
Exposing modern forgers
Researchers at ETH Zurich have developed a process that can provide conclusive evidence with regard to modern fakes of paintings, even in cases where the forger recycled older canvases. This verification process requires less than 200 micrograms of paint. Art forgeries have been around since ancient times.

The geometry of an electron determined for the first time
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer.

Shedding light on cancer metabolism in real-time with bioluminescence
Shedding light on cancer metabolism in real-time with bioluminescence
Cancerous tumors can be made to bioluminesce, like fireflies, according to the level of their glucose uptake, giving rise to a technique for quantifying metabolite absorption. The firefly imaging technique for sugar can be translated from cancer to many other metabolic diseases. EPFL scientists have invented a new way to quantify - in real-time - glucose metabolism of cancerous tumors by making them bioluminesce.
