Water molecules distort the electrical resistance of graphene, but a team of European researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact resistance is not impaired by humidity. This finding will help to develop new sensors -the interface between circuits and the real world- with a significant […]
New Smart System to Reduce Queues at Roundabouts
Long queues at certain approaches to some roundabouts could be reduced using magnetic detection devices under the road surface, which would activate a traffic metering signal at another, less congested approach. Researchers at the Universitat Politecnica de Valencia (Spain) have released a guide for technicians to implement this intelligent traffic system, already used on roundabouts […]
Chemical Fingerprints Confirm The Saffron Fraud
Saffron from Spain is one of the world’s most superior varieties, but the majority of this product which is labelled and exported as such originates in other countries. Scientists from the Czech Republic and Spain confirmed this false labelling after analysing 44 commercial products. By using a new technique based on each type of saffron’s […]
Pressing the Accelerator on Quantum Robotics
Quantum computing will allow for the creation of powerful computers, but also much smarter and more creative robots than conventional ones. This was the conclusion arrived at by researchers from Spain and Austria, who have confirmed that quantum tools help robots learn and respond much faster to the stimuli around them. Quantum mechanics has revolutionized […]
