New surface treatment could improve refrigeration efficiency

Unlike water, liquid refrigerants and other fluids that have a low surface tension tend to spread quickly into a sheet when they come into contact with a surface. But for many industrial process it would be better if the ...

Physicists discover new type of spin waves

Current technologies for information transfer and processing are challenged by fundamental physical limits. The more powerful they become, the more energy they need, and the more heat is released to the environment. Also, ...

Researchers discover new charge transfer and separation process

Charge transfer and separation is a fundamental process in the energy conversion that powers life on Earth. Besides deployment in solar cells and photocatalysts, this process is found in photosynthesis, as it enables energy ...

Using 60% less water in paper production

An EPFL researcher has developed a mathematical model for optimizing heat transfer in factories and dramatically reducing water and energy consumption. The model could, in theory, cut water use by 60 percent at a Canadian ...

Using DNA templates to harness the sun's energy

As the world struggles to meet the increasing demand for energy, coupled with the rising levels of CO2 in the atmosphere from deforestation and the use of fossil fuels, photosynthesis in nature simply cannot keep up with ...
