Machine learning predicts heat capacities of MOFs
Machine learning predicts heat capacities of MOFs
Chemical engineers at EPFL have developed a machine-learning model that can accurately predict the heat capacity of the versatile metal-organic framework materials. The work shows that the overall energy costs of carbon-capture processes could be much lower than expected. Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores.

Accurately tracking how plastic biodegrades
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. 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.

Mapping human brain development
Mapping human brain development
Researchers at ETH Zurich are growing human brain-like tissue from stem cells and are then mapping the cell types that occur in different brain regions and the genes that regulate their development. The human brain is probably the most complex organ in the entire living world and has long been an object of fascination for researchers.

Stabilizing polarons opens up new physics
Stabilizing polarons opens up new physics
Physicists at EPFL have developed a formulation to solve the longstanding problem of electron self-interaction when studying polarons - quasiparticles produced by electron-phonon interactions in materials. The work can lead to unprecedented calculations of polarons in large systems, systematic studies of large sets of materials, and molecular dynamics evolving over long time periods.

New reaction facilitates drug discovery
Chemists at ETH Zurich have found a facile method that allows a commonly used building block to be directly converted into other types of important compounds. This expands the possibilities of chemical synthesis and facilitates the search for new pharmaceutically active ingredients. Medications are continuously becoming more precise and efficient.

Combining forces for the energy transition
Combining forces for the energy transition
The Paul Scherrer Institute PSI and the start-up AlphaSYNT have a common mission. By signing a cooperation and licensing agreement, they aim to commercialise a novel approach to "power-to-gas" conversion, or to be more specific: "power-to-methane". The innovative methanation process developed by PSI will allow energy to be stored as methane gas in future.

In control of chaos
In control of chaos
Crystals consisting of wildly mixed ingredients - so-called high-entropy materials - are currently attracting growing scientific interest. Their advantage is that they are particularly stable at extremely high temperatures and could be used, for example, for energy storage and chemical production processes.

A paper battery with water switch
A paper battery with water switch
A team of researchers at Empa developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics - such as smart labels for tracking objects, environmental sensors and medical diagnostic devices - and minimize their environmental impact.

Attosecond measurement on electrons in water clusters
Attosecond measurement on electrons in water clusters
Researchers at ETH Zurich have developed a method that enables time-resolved measurements of electron motion in water clusters lasting only a few attoseconds. The technique can be used for more detailed studies of water as well as faster electronics. Virtually all vital chemical processes take place in aqueous solutions.

Virtual fish instead of animal testing
Virtual fish instead of animal testing
As part of a new national research programme that aims to replace animal experiments in research, the National Science Foundation is supporting a project at Eawag. This opens up new possibilities for determining the toxicity of chemical substances based solely on tests with cultured cells and computer models.

Chemistry boosts drug libraries
Chemistry boosts drug libraries
Scientists at EPFL have found a way to synthesize large numbers of macrocyclic compounds, which are needed for developing drugs against difficult disease targets. When pharmaceutical companies begin looking for a drug candidate, they use a filtering process known as "high-throughput screening". Here, large numbers of different chemical compounds are tested to see which will bind to a protein that is the target of the disease they want to address.

New insights into the Earth's formation
New insights into the Earth’s formation
An international research team led by ETH Zurich proposes a new theory for the Earth's formation. It may also show how other rocky planets were formed. Although the Earth has long been studied in detail, some fundamental questions have still to be answered. One of them concerns the formation of our planet, about whose beginnings researchers are still unclear.

Shedding light on comet Chury's unexpected chemical complexity
Shedding light on comet Chury’s unexpected chemical complexity
A team of researchers led by the University of Bern has for the first time identified an unexpected richness of complex organic molecules at a comet. This was achieved thanks to the analysis of data collected during ESA-s Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. Delivered to the early Earth by impacting comets, these organics may have helped to kick-start carbon-based life as we know it.

Making it easier to differentiate mirror-image molecules
Making it easier to differentiate mirror-image molecules
Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from Paul Scherrer Institute PSI, EPF Lausanne (EPFL), and the University of Geneva describe the new method in the scientific journal Nature Photonics .

New PET-like plastic made directly from waste biomass
New PET-like plastic made directly from waste biomass
Scientists have developed a new, PET-like plastic that is easily made from the non-edible parts of plants. The plastic is tough, heat-resistant, and a good barrier to gases like oxygen, making it a promising candidate for food packaging. Due to its structure, the new plastic can also be chemically recycled and degrade back to harmless sugars in the environment.

Mucus molecules can thwart fungal infection
Mucus molecules can thwart fungal infection
Candida albicans is a yeast that colonizes the mucosal surfaces of most healthy humans. Under certain conditions, it can switch to a harmful form and cause infection. Researchers have now identified components of mucus that keep the pathogen from turning destructive, thus laying the foundation for a new class of drugs.

A new database shows which packaging contains harmful substances that can be transferred to its contents. It also includes findings from researchers at the University of Basel, who are investigating plastic molecules that were previously unknown or barely known.
