Experiments show dramatic increase in solar cell output

Researchers have found a way to increase the output of silicon solar cells by allowing a single photon to release two electrons in the silicon.

Magnetic monopoles make acoustic debut

University College Cork (UCC) & University of Oxford Professor of Physics, Séamus Davis, has led a team of experimental physicists in the discovery of the magnetic noise generated by a fluid of magnetic monopoles.

Physicists develop model that describes length growth in biological systems

"Grandmother, why do you have such big ears?" is one of the most well-known questions in literature, posed of course by Red Riding Hood as she hesitantly observes the wolf dressed in her Grandmother's clothes. Had Red Riding Hood been a physicist, she might well have asked: "Grandmother, why are your two ears exactly the same length?"

'Tsunami' on a silicon chip: A world first for light waves

Scientists have for the first time manipulated a light wave, or photonic information, on a silicon chip that retains its overall 'shape'. This foundational work is important because most communications infrastructure still relies on silicon-based devices for propagation and reception of information. Manipulating solitons on-chip could potentially allow for the speed up of photonic communications devices and infrastructure.

Physicists develop model that describes length growth in biological systems

One of science's unsolved puzzles is that concerning the growth of biological systems. Whether it's a microscopic protozoa or a blue whale, all living systems grow. Physicists have now discovered a mechanism that could well provide a means to explain this mystery. They have developed a mathematical model that offers a precise explanation of growth in biological systems.

Magnets shown to create more power in electrical generators

Electric generators have a plethora of uses—ranging from automotive to aircraft to microgrids. There is currently a strong desire to reduce the size and increase the efficiency of the devices.

Tiny supersonic jet injector accelerates nanoscale additive manufacturing

By energizing precursor molecules using a tiny, high-energy supersonic jet of inert gas, researchers have dramatically accelerated the fabrication of nanometer scale structures. The rapid additive manufacturing technique also allows them to produce structures with high aspect ratios. Now, a theory developed to describe the technique could lead to new applications for additive nanomanufacturing and new nanoscale materials.

Neural nets to simulate molecular motion cast

New work is showing that artificial neural nets can be trained to encode quantum mechanical laws to describe the motions of molecules, supercharging simulations potentially across a broad range of fields.

Researchers cast neural nets to simulate molecular motion

New work from Los Alamos National Laboratory, the University of North Carolina at Chapel Hill, and the University of Florida is showing that artificial neural nets can be trained to encode quantum mechanical laws to describe the motions of molecules, supercharging simulations potentially across a broad range of fields.

Tiny granules can help bring clean and abundant fusion power to Earth

Physicists have concluded that injecting tiny beryllium pellets into ITER could help stabilize the plasma that fuels fusion reactions.
