Gold membrane coaxes secrets out of surfaces

Thousand-fold signal amplification

26-Jun-2024 - Using a special wafer-thin gold membrane, ETH researchers have made it significantly easier to study surfaces. The membrane makes it possible to measure properties of surfaces that are inaccessible to conventional methods. “Surfaces were invented by the devil” - this quote is attributed to the ...

Protecting art and passwords with biochemistry

New technology is based on a pool of one hundred million different DNA molecules and protects against counterfeiting

10-Apr-2024 - A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers. Instead of using algorithms, the method employs the polymerase chain reaction (PCR) and DNA sequencing. Security experts fear Q-​Day, the ...

Ocean acidification in coloured stripes

Making environmental changes visible

15-Sep-2023 - Our oceans are acidifying rapidly. Climate researchers from ETH Zurich are now illustrating these chemical changes with colour-​coded stripes. Global observations of ocean acidification over the last four decades serve as the basis. Most people consider climate change to consist only of the ...

Accurate rapid tests made from smart graphene paper

The potential range of applications covers virtually all chemical, biological and medical analyses that can be performed in aqueous solutions

29-Mar-2023 - A team led by ETH Zurich chemical engineers Chih-​Jen Shih and Andrew deMello have developed a rapid test system made of smart graphene paper. It only costs a few cents per test strip, is easy to use but is as accurate as lab measurements. The approach will impact more than just disease ...

New corrosion protection that repairs itself

An extraordinary corrosion protection was created from a chance find: It glows in places where it is not damaged, repairs itself – and can be reused multiple times

22-Feb-2023 - Skyscrapers, bridges, ships, aeroplanes, cars – everything humans make or build sooner or later decays. The ravages of time are known as corrosion; nothing is safe from it. This makes the fight against corrosion expensive. All countries together invest around 3.5 percent of annual global gross ...

Sustainable scents from the mountain of the gods

ETH Zurich chemist Michailidou could see herself founding her own start-​up: “That would be a dream come true”

15-Nov-2022 - ETH Zurich chemist Freideriki Michailidou is developing novel processes for the sustainable production of fragrance ingredients. As a first step, she studied the scents of rare aromatic plants that grow only on Mount Olympus in Greece. How a product smells affects how we respond to it. So it ...

Accurately tracking how plastic biodegrades

Researchers at ETH Zurich have developed an approach to accurately record and fully track the biodegradation of plastics in soils

14-Oct-2022 - Modern agriculture uses a lot of plastic, especially in the form of mulch film that farmers use to cover field soils. This keeps the soils moist for crops, suppresses weeds and promotes crop growth. However, it is usually very time-​consuming and costly for farmers to collect and dispose of ...

ETH Zurich researchers want to make salt printing marketable

They have also come up with a name for their start-up: “Sallea”, a portmanteau of “salt leaching”.

06-Oct-2022 - Materials scientists Nicole Kleger and Simona Fehlmann have developed a 3D printing process for creating salt templates that they can fill with other materials. One area of application is the creation of highly porous lightweight metal components. The two Pioneer Fellows are now trying to ...

One more clue to the Moon’s origin

Researchers from ETH Zurich discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth’s mantle

18-Aug-2022 - The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed. Humankind has maintained an enduring fascination with the Moon. It was not until Galileo’s time, however, that scientists really began ...

Light amplification accelerates chemical reactions in aerosols

Temporal sequence of photochemical reaction in individual aerosol particles observed with high resolution

21-Apr-2022 - Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid ...
