Diamond watch components

19-Jun-2018

SNSF-funded researchers have developed a new technique for carving materials to create micromechanical systems. In particular, they have created a miniscule watch component out of synthetic single-crystal diamond. Diamond is very hard and elastic, a very good thermal conductor and highly ...

The first precise measurement of a single molecule's effective charge

Discovery could pave the way to new diagnostic tools

16-Jan-2018

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics. Electrical charge is one of the key properties that allows molecules to ...

Liquid shock absorbers

10-Nov-2017

Remarkable liquid materials called colloids stiffen under impact. Researchers funded by the SNSF have studied the effect of powerful impacts such as those produced by firearms or micrometeorites. At first glance, colloids resemble homogeneous liquids such as milk or blood plasma. But in fact ...

Sodium and magnesium to replace lithium in batteries

03-May-2017

A project supported by the Swiss National Science Foundation (SNSF) aims to find new materials which can be used in rechargeable batteries and eventually provide alternatives to the current lithium batteries. Lithium-based batteries have several drawbacks, such as the limited availability of the ...

How nanoparticles flow through the environment

13-May-2016

Carbon nanotubes remain attached to materials for years while titanium dioxide and nanozinc are rapidly washed out of cosmetics and accumulate in the ground. Researchers from the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64) have developed a new model to track ...

Using a microscopic ring to produce pulsed light

08-Jan-2016

Researchers funded by the Swiss National Science Foundation have made a chip-based device that can generate a laser signal with frequencies spaced in a comb-like fashion. Their work could be used in telecommunications applications and in chemical analysis In general, light and water waves alike ...

Cotton fibres instead of carbon nanotubes

11-May-2015

Plant-based cellulose nanofibres do not pose a short-term health risk, especially short fibres, shows a study conducted in the context of National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64). But lung cells are less efficient in eliminating longer fibres. Similar to ...

Barely any nanosilver from consumer products in the water

19-Apr-2013

Nanosilver in wastewater can cause severe environmental damage if it occurs as a metal. A study conducted within the scope of the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64) now shows that nanosilver is quickly transformed into less problematic substances on ...
