Schematic of a two-step method for the synthesis of transition metal carbide nanoparticles dispersed on a carbon material

Researchers have developed a new technology that could speed up the commercialization of fuel cell vehicles. A team of engineers at the University of Delaware has made a catalyst of tungsten carbide, which goes for around $150/kg instead of using expensive platinum at $30,000/kg. They produced tungsten carbide nanoparticles in a novel way, much smaller and more scalable than previous methods.

“The material is typically made at very high temperatures, about 1,500 Celsius, and at these temperatures, it grows big and has little surface area for chemistry to take place on,” said Dionisios Vlachos, director of UD’s Catalysis Center for Energy Innovation...

It looks like a regular roof, but the top of the Packard Electrical Engineering Building at Stanford University has been the setting of many milestones in the development of an innovative cooling technology that could someday be part of our everyday lives...

The research study contributes to our basic understanding of random matrices and the theory of quantum chaos.

Researchers have now succeeded in formulating a mathematical result that provides an exact answer to the question of how chaos actually behaves. The researchers have analyzed chaotic states at the atomic level. The world in there behaves a lot differently to the world that we experience; the protons and neutrons in the nucleus are waves. In this microcosmos, the so-called quantum world, the normal rules of nature do not apply, but in terms of the state called chaos, there are universal features that are present, regardless of the level of existence.

In a new study, a research group including researchers from Lund University, has therefore set out to tackle the theory of quantum cha...

Images from a new camera that can detect tiny traces of light through the body’s tissues. Here, the camera is detecting light emitted from a medical device known as an optical endomicroscope whilst in use in sheep lungs. Image on left shows light emitted from the tip of the endomicroscope, revealing its precise location in the lungs. Right image shows the picture that would be obtained using a conventional camera, with light scattered through the structures of the lung. Credit: University of Edinburgh

Scientists have developed a camera that can see through the human body and is designed to help doctors track endoscopes that are used to investigate a range of internal conditions...
