ID microstructure of stock useful in financial crisis

Every day, thousands of orders for selling or buying stocks are registered and processed within milliseconds. Electronic stock exchanges, such as NASDAQ, use what is referred to as microscopic modelling of the order flow ...

New step towards future complex oxide electronics

Researchers from TU Delft, Cornell University and the University of Cagliari report an interesting method for turning a highly insulating material into a highly conducting system. The process involves combining three different ...

Topological insulators—one glimpse is enough

The Nobel Prize for physics in 2016 was awarded for the theory of topological matter. Topological insulators are new materials with special electronic properties and are of great fundamental and applications-oriented interest. ...

Physics forecasts for fracking and fuels

Society's demand for energy relies mainly on oil and gas, which are finite resources. Future technologies could reduce the consumption of energy, but until then, existing resources must be carefully managed. Director of the ...

Reusing waste energy with 2-D electron gas

More than 60 percent of the energy produced by fossil fuels is lost as heat. Thermoelectric energy conversion has attracted much attention as a way to convert waste heat from power plants, factories and cars into electricity. ...

Glass microparticles enhance solar cells efficiency

Scientists from ITMO University have suggested a new solar cell coating that combines features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid ...

Researchers tunnel to a new light source

With concerns over moving to a clean energy platform worldwide with electric vehicles and renewables, wasted energy is a factor as important as the amount of green energy produced. Thus, solid-state lighting based upon light-emitting ...
