Predicting crystal structures A group of researchers have improved a crystal structure prediction algorithm, enabling the ability to develop new crystal structures and compounds at faster rates. In 2005, Artem Oganov, now a professor at the Skolkovo Institute of Science and Technology (Skoltech) and the Moscow Institute of Physics and Technology (MIPT), developed a crystal structure predic... » read more

Tandem solar reaches 25.2% efficiency In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power. Recently, two groups have reache... » read more

Atomristors for thin memory Engineers at The University of Texas at Austin and Peking University developed a thin memory storage device with dense memory capacity. Dubbed "atomristors," the device enables 3-D integration of nanoscale memory with nanoscale transistors on the same chip. "For a long time, the consensus was that it wasn't possible to make memory devices from materials that were... » read more

Healing perovskites A team from the University of Cambridge, MIT, University of Oxford, University of Bath, and Delft University of Technology discovered a way to heal defects in perovskite solar cells by exposing them to light and just the right amount of humidity. While perovskites show promise for low-cost, efficient photovoltaics, tiny defects in the crystalline structure, called traps,... » read more

Even good bots fight: The case of Wikipedia (Oxford & Alan Turing Institute)
By Technical Paper Link - 06 Mar, 2017 - Comments: 0

Source: University Of Oxford published via PLOS ONE, Milena Tsvetkova, Ruth García-Gavilanes, Luciano Floridi, Taha Yasseri "The research paper, published in PLOS ONE, concludes that bots are more like humans than you might expect as they appear to behave differently in culturally distinct online environments. The paper says the findings are a warning to those using artificial intelligence ... » read more

Software robots have fights lasting years According to University of Oxford and Alan Turing Institute researchers, editing bots on Wikipedia undo vandalism, enforce bans, check spelling, create links and import content automatically, whereas other non-editing bots mine data, identify data or identify copyright infringements — sometimes with unpredictable consequences. The team looked at h... » read more

Record-breaking quantum logic gate Reaching the benchmark required theoretically to build a quantum computer, University of Oxford researchers have achieved a quantum logic gate with record-breaking 99.9% precision. They reminded that quantum computers, which function according to the laws of quantum physics, have the potential to dwarf the processing power of today's computers, able to pro... » read more

Building MEMS at one-hundredth the cost The microelectromechanical systems (MEMS) market was $12 billion business in 2014, dominated by a handful of devices, such as accelerometers that reorient the screens of most smartphones. However, researchers at MIT pointed out that potentially useful MEMS have languished in development because they don’t have markets large enough to justify the initia... » read more
