  • – Physicists have discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.

    Working with an international team of physicists, University of Tokyo Professor Yoshihiro Iwasa was exploring possible functions of a special semiconductor nanotube when he had a lightbulb moment. He took this proverbial lightbulb (which was in reality a laser) and shone it on the nanotube to discover something enlightening. Certain wavelengths and intensities of light induced a current in the sample—this is called the photovoltaic effect. There are several photovoltaic materials, but the nature and behavior of this nanotube is cause for excitement.

    “Essentially our research material generates electricity like solar panels, but in a different way,” said Iwasa. “Together with Dr. Yijin Zhang from the Max Planck Institute for Solid State Research in Germany, we demonstrated for the first time nanomaterials could overcome an obstacle that will soon limit current solar technology. For now solar panels are as good as they can be, but our technology could improve upon that.” | go to source

  • Tech Explorist – Yale scientists now have come up with a more accurate way to help classify phases of matter.

    Understanding the complexities of these phases could open leaps forward in quantum computing and materials science. A portion of these phases could be utilized as quantum hard drives that will store quantum information. That is the reason researchers are effectively looking for new ways to deal with describing and characterize them….

    Dua said, “Topological phases represent an important class of phases of matter. Their study and methods for diagnostics are important, and identifying the right diagnostic tools is fundamental.”

    The findings appear in a recent study published in the journal Physical Review Letters and a follow-up work published in Physical Review B. | go to source

  • France 24 – Xi is the first Chinese president to visit North Korea in 14 years, after relations between the Cold War era allies deteriorated over Pyongyang’s nuclear provocations and Beijing’s subsequent backing of UN sanctions.

    Xi and Kim have been working to repair ties, with the young North Korean leader visiting his older ally four times in China in the past year and Beijing calling for sanctions to be relaxed.

    But the Chinese leader waited to reciprocate the visit, biding his time to see how nuclear talks between Kim and Trump would play out before deciding to travel to Pyongyang, according to analysts. | go to source

  • Space Daily – The money transfer business is personal for Ismail Ahmed. It was cash wired by his family that allowed him to make the final leg of his journey from escaping fighting in his native Somaliland to London in 1988 to take up a university scholarship.

    Today, Ahmed leads WorldRemit, one of a handful of fintech firms that is upending the remittances business that has long been dominated by three US firms — Western Union, MoneyGram and Ria — as well as banks.

    Piggybacking on the development of mobile money systems in Africa and other developing countries, these fintech firms offer migrant labourers a more convenient way to send money home at a lower cost. | go to source
