EFSA’s ongoing work
EFSA is currently involved in a number of initiatives to develop scientific knowledge in the field of endocrine active substances and also on overlapping issues such as non-monotonic dose-response relationships and biological relevance in risk assessment. This work follows up on a 2013 scientific ...
Using electrochemistry, researchers have created a reconfigurable, voltage-controlled liquid metal antenna
Researchers have held tremendous interest in liquid metal electronics for many years, but a significant and unfortunate drawback slowing the advance of such devices is that they tend to require external pumps that can't be easily integrated into electronic systems.So a team of North Carolina ...
Scientists from Paris and Helmholtz-Zentrum Berlin have been able to switch ferromagnetic domains on and off with low voltage in a structure made of two different ferroic materials. The switching works slightly above room temperature. Their results, which are published online in Scientific ...
Simple design mimics pumping mechanism of life-sustaining proteins found in living cells
Using nature for inspiration, a team of Northwestern University scientists is the first to develop an entirely artificial molecular pump, in which molecules pump other molecules. This tiny machine is no small feat. The pump one day might be used to power other molecular machines, such as ...
A variety of chemicals are known to cause allergic sensitisation of the respiratory tract associated with allergic rhinitis and asthma. It is generally accepted that the development of sensitisation of the respiratory tract to chemicals is a threshold phenomenon. That is, a certain minimum level ...
Parallel production reduces energy consumption by two thirds
Crystalline semiconductor components form the core of many modern communication technologies such as computers and mobile phones. They are produced during a multi-day pulling process that uses considerable energy. The BINE-Projektinfo brochure “Efficient production of monocrystalline ...
Quantum dots are an ideal nanolab to study the means to turning heat into electricity
Just as alchemists always dreamed of turning common metal into gold, their 19th century physicist counterparts dreamed of efficiently turning heat into electricity, a field called thermoelectrics. Such scientists had long known that in conducting materials the flow of energy in the form of heat ...
Aalto University's researchers improved their previous record by over 3 absolute percents
The researchers from Finland's Aalto University and Universitat Politècnica de Catalunya have obtained the record-breaking efficiency of 22.1% on nanostructured silicon solar cells as certified by Fraunhofer ISE CalLab. An almost 4% absolute increase to their previous record is achieved by ...
Nano-sized faucet offers experimental support for longstanding quantum theory
We all know intuitively that normal liquids flow more quickly as the channel containing them tightens. Think of a river flowing through narrow rapids. But what if a pipe were so amazingly tiny that only a few atoms of superfluid helium could squeeze through its opening at once? According to a ...
Led by the University of Surrey, a team of researchers from the Netherlands Forensic Institute (NL), the National Physical Laboratory (UK), King’s College London (UK) and Sheffield Hallam University (UK), used different types of an analytical chemistry technique known as mass spectrometry to ...
