Sustainable Roads: The Evolution of Asphalt Recycling

Switzerland is built, at least as far as the road network is concerned. Therefore – and despite recycling –, significantly more reclaimed asphalt is generated today than can be reused in new roads. Empa researcher Martins Zaumanis has set himself the goal of increasing the recycled content of asphalt – with adapted production methods and Read more about Sustainable Roads: The Evolution of Asphalt Recycling[…]

Perovskite nanocrystals for better computing

Researchers at Empa, ETH Zurich and the “Politecnico di Milano” are developing a new type of computer component that is more powerful and easier to manufacture than its predecessors. Inspired by the human brain, it is designed to process large amounts of data fast and in an energy-efficient way. In many respects, the human brain Read more about Perovskite nanocrystals for better computing[…]

New reactor concept for methanation

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, Empa researchers have developed a new, optimized reactor concept for methanation. Read more about New reactor concept for methanation[…]

Flexible solar cells with record efficiency of 22.2%

One year after announcing an efficiency record, Empa scientists have achieved a new mark of 22.2% for flexible CIGS solar cell on polymer film. Solar cells of this type are especially suited for applications on buildings, vehicles, satellites, airships, and mobile devices. Empa researchers have – once again – improved the efficiency of CIGS flexible Read more about Flexible solar cells with record efficiency of 22.2%[…]

The next-generation VR glove will make virtual worlds tangible

Together with EPFL and ETH Zurich colleagues, an Empa team is developing next-generation VR gloves that will make virtual worlds tangible. The glove is to be tailored to each user and capable of being produced largely automatically – using a 3D printing process. Research sometimes needs a sacrifice. Empa researcher Patrick Danner has just made Read more about The next-generation VR glove will make virtual worlds tangible[…]

Artificial Intelligence Save Energy

With energy prices soaring, heating costs will also inevitably rise in the coming winter. In order to mitigate this, solutions for operating buildings more efficiently are needed. The Empa spin-off viboo has developed an algorithm that makes it possible to operate even older buildings with around 25 percent less energy – while user comfort remains Read more about Artificial Intelligence Save Energy[…]

How classic cars are to become climate-neutral

Synthetic fuels can make a contribution to achieving climate targets. But can they be used in conventional combustion engines without any problems? This question is being investigated by Empa in collaboration with the Swiss car importer AMAG. Even though it is now obvious that the future of passenger cars is likely to be largely electric, Read more about How classic cars are to become climate-neutral[…]

A new circular business model for the production optimization

The research project CircuBAT aims to create a circular business model for the production, application and recycling of lithium-ion batteries used for mobility purposes. Seven Swiss research institutions and 24 companies are joining forces to look for ways to boost sustainability in all stages of a battery’s life cycle. The project is part of the Read more about A new circular business model for the production optimization[…]

Using quantum physics to generate electricity

Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology would be ideally suited for low-power electronics applications such as wearables or low-cost Internet-of-Things devices. This includes, for Read more about Using quantum physics to generate electricity[…]

Traffic jam analyzed by AI

How much does a country’s vehicle fleet consume on average? How does it change from year to year? With the increasing number of electric vehicles and more and more “crossover” models that can hardly be assigned to one vehicle segment, analysis is becoming increasingly difficult. Empa researchers analyze databases using deep learning methods – and Read more about Traffic jam analyzed by AI[…]

Electricity from wooden floors

Researchers at Empa and ETH Zurich have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor – or generate usable energy. The latest highlight: To ensure that the process does not require aggressive chemicals, naturally occurring Read more about Electricity from wooden floors[…]

Unmanned Aerial Sensor Placement for Cluttered Environments

A team of researchers from Empa and Imperial College London developed drones that can attach sensors to trees to monitor environmental and ecological changes in forests. Sensors for forest monitoring are already used to track changes in temperature, humidity and light, as well as the movements of animals and insects through their habitats. They also Read more about Unmanned Aerial Sensor Placement for Cluttered Environments[…]
