Surprisingly strong and deformable silicon

Researchers at ETH and Empa have shown that tiny objects can be made from silicon that are much more deformable and stronger than previously thought. In this way, sensors in smartphones could be made smaller and more robust.

An artificial 'tongue' of gold to taste maple syrup

It's said that maple syrup is Quebec's liquid gold. Now scientists at Université de Montréal have found a way to use real gold—in the form of nanoparticles—to quickly find out how the syrup tastes.

Sustainable separation technology makes new applications possible

Membranes are widely used to separate substances from each other, for example in water treatment or kidney dialysis. Membrane technology saves energy and water, and has a small CO2 footprint. Unfortunately, large quantities ...

Colloidal gel properties under the microscope

Researchers at the University of Tokyo have devised a method for following the gelation of colloidal gels. Their confocal microscopy technique has allowed the different stages of the process to be analyzed, leading to insights ...

Authenticating the geographic origin of hazelnuts

Hazelnuts, like olive oil, cheese and other agricultural products, differ in flavor depending on their geographic origin. Because consumers and processors are willing to pay more for better nuts—especially in fine chocolates ...

Do kitchen items shed antimicrobial nanoparticles after use?

Because of their antimicrobial and antifungal properties, silver nanoparticles measuring between one and 100 nanometers (billionth of a meter) in size, are being incorporated outside the United States into a variety of kitchen ...

New app launched to explain benefits of carbon dioxide

A new app to explain how Carbon Dioxide (CO2) can be used to make products, therefore lowering emissions, has been launched at COP22 in Marrakech today (Friday 11 November 2016).
