Mussel powder engineered to kill pathogens

Hydrogen peroxide is a commonly used disinfectant. A typical household may have a bottle of 3% hydrogen peroxide solution for disinfecting minor cuts and scrapes. Concentrated hydrogen peroxide is also used in municipal wastewater and drinking water treatments, in petrochemical refinery applications, and in bleaching... click to read more

Compressed air energy storage: a technology that (porous) rocks!

Climate Change is caused, in parts, by the increase in greenhouse gas emissions, such as carbon dioxide, to the atmosphere. One of the main sources of carbon dioxide is power plants. Hence, more and more renewable energy sources, commonly known as "renewables", such as wind,... click to read more

Can robots teach us about animal flight?

Insights into animal flight control are of great interest not only for biologists but also for designers of bio-inspired flying robots. The common approach in animal flight research is to record the animals while maneuvering with high-speed cameras. The footage is processed to reconstruct the... click to read more

Leidenfrost reinvents the wheel

We often test the temperature of our frying pans by throwing a few droplets of water: if they skate over the hot surface, it is time to cook our pancakes! Water mobility indeed arises above a well-defined temperature, as described in 1756 by Johan Leidenfrost... click to read more

Silencing a quantum drum

To a classical physicist, there is no fundamental limit to how well you can measure something. A classical object, for example, always exists in a well-defined position; if you want to know that position with better accuracy, you simply build a better microscope. The story... click to read more
