To achieve climate neutrality in the chemical industry, we must also cut demand
Innovative production technologies are crucial to the chemical industry's net-zero endeavour - but they're not always enough, says Paolo Gabrielli. Chemical products, such as plastics, fertilisers and solvents pervade our modern lifestyle. The vast majority are derived from crude oil or natural gas - and producing them generates around 5 percent of global CO2 emissions.

Crystalline light catchers
Three institutes in the ETH Domain are conducting research on so-called perovskite-based optoelectronics, such as solar cells, photodetectors, and light-emitting diodes (LEDs). In a project called AMYS, labs of EPFL, ETH Zurich and Empa have now joined forces for four years to explore new chemical compositions, but also simple and scalable low cost production methods.

Robust and flexible to synthetic methane
Synthetic energy carriers are carbon-neutral and make renewable energy transportable and storable in the long term. Synthetically produced methane is one of them. The problem: The production involves rather high energy losses; moreover, existing processes require the methane to be purified. To change this, researchers have developed a new, optimized reactor concept for methanation.

Sustainable scents from the mountain of the gods
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. To tackle this challenge, she scaled Mount Olympus this past summer. She took along one of the ETH Biocommunication group's headspace traps, a device equipped with a glass bell or a plastic bag, which is placed carefully over a plant.

Hitting the bull’s eye
In the FOXIP project, researchers form Empa, EPFL and the Paul Scherrer Institute attempted to print thin-film transistors with metal oxides onto heat-sensitive materials such as paper or PET. The goal was ultimately not achieved, but those involved consider the project a success - because of a new printing ink an a transistor with "memory effect".

Industrial wastewater: even state-of-the-art treatment plants do not eliminate all contaminants
Even though industrial wastewater is treated at state-of-the art plants, the sheer variety of synthetic organic compounds from the chemical and pharmaceutical industry which end up in surface waters are seriously underestimated.

Boosting learning by putting theory into practice
Summer series - Master's project (3). Two groups of EPFL students turned their blueprints into functional prototypes: a self-heating food box and a self-cooling vaccine transport container. For engineers, little can be more satisfying than turning your ideas into working objects you can see and touch.

Watching how cells deal with stress
FMI researchers developed an imaging approach that allowed them to visualize individual molecules involved in the cell's response to stress. When a cell is exposed to stressors such as toxins, it switches on pathways aimed at repairing damage. One of these pathways is called the 'unfolded protein response', which senses unfolded or misfolded proteins in the endoplasmic reticulum — a cell organelle designated for folding proteins destined to other organelles or to be secreted by the cell.

Aiming at an industry without CO2 emissions
On 20 June, the Association for the Decarbonization of Industry with representatives from industry, energy suppliers, the financial sector and research adopted a joint strategy with the aim of developing holistic approaches for CO2 cuts in industrial applications that can rapidly be implemented. The focus is on high-temperature processes and logistics.

Chemical data management: an open way forward
Writing , three scientists propose an open platform for managing the vast amounts of diverse data produced in chemical research. Based on principles of accessibility, collaboration and efficiency, the proposed platform could be spearheaded by EPFL. One of the most challenging aspects of modern chemistry is managing data.

Can oil and water mix?
Common experience tells us that oil and water do not mix. Yet, it turns out that they can mix when oil is dispersed as small droplets in water. This strange behavior has long vexed scientists because there is no explanation for it. A team of EPFL and ICTP scientists have studied this question using novel optical technology and discovered the mechanism by which these two neutral and immiscible compounds can in fact mix together and form emulsions.

3D chemistry boosts perovskite efficiency to 23.9%
An international collaboration led by EPFL chemical engineers has overcome a problem in the manufacturing of perovskites that reduces their efficiency as solar panels. The approach produced perovskite solar panels with an efficiency of 23.9% and operational stability longer than 1000 hours. Perovskites are hybrid compounds made from metal halides and organic constituents, and show great potential in a range of applications, e.g. LED lights, lasers, and photodetectors.

CO2 can be turned into a valuable resource
In a new study, researchers from the Paul Scherrer Institute PSI show that CO2 electrolysis can not only be profitable, but can also contribute to climate protection. With this method, carbon dioxide is captured from the atmosphere or at the point of production, such as an industrial plant. An electrolysis cell then converts the gas for industrial use, such as in chemicals production.

We need a global science panel on chemicals and waste
Chemical pollution is a global threat that demands for global action, says Zhanyun Wang. An interface body similar to the IPCC could help bridge the gap between science and policy. Chemicals are at the heart of our modern world. But the way the world deals with chemicals is highly inadequate. Over the last decades, the number and diversity of chemicals produced and traded have increased drastically, reaching several hundred thousands.
