Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
Researchers at Tohoku University have announced the development of a nonvolatile microcontroller unit (MCU) which achieves both high performance and ultra-low power by utilizing spintronics-based VLSI design technology.
According to the World Health Organization, Delhi is the world's most polluted large city. And it's only going to get worse if something isn't done about it, say some experts in an article in Chemical & Engineering News (C&EN), ...
Facebook has been likened to a "digital gangster" by a critical parliamentary report into disinformation and fake news. One witness in the 18-month inquiry into the way digital platforms have transformed the flow of information ...
Coal-fired power plants produce more than just carbon dioxide, which contributes to global warming. Coal burning also releases particulate matter, sulphur dioxide, nitrogen oxide and mercury—thus damaging the health of ...
Although conventional wisdom suggests that poor countries are more likely to bear a disproportionate burden of a worldwide carbon tax on fossil fuels used for electricity and transportation, the potential consequences of ...
Agriculture has become a carbon-intensive endeavour. Crop, livestock and fossil fuel use in agriculture account for about 25 per cent of global greenhouse gas (GHG) emissions.
The UK's efforts to develop facilities to remove carbon emissions from power stations took a step forward with news of a demonstrator project getting underway at the Drax plant in north Yorkshire. Where most electricity carbon ...
Most schoolchildren learn that the Earth has three (or four) layers: a crust, mantle and core, which is sometimes subdivided into an inner and outer core. That's not wrong, but it does leave out several other layers that ...
