Equities rose with oil prices and the dollar weakened Tuesday as China avoided another night of protests after a weekend of unrest, with speculation growing that officials will announce a further easing of the country's strict Covid containment measures. The gains were led by a rally in Hong Kong and Shanghai, with property firms enjoying a much-needed surge on the back of moves to ease fund

Recent developments have enabled perovskite solar cells (PSCs) to achieve power conversion efficiencies exceeding 25.7%; thus, these devices are considered rising stars in the photovoltaics field. However, the homogeneous crystallization of perovskite may lead to disordered crystalline orientations and defects in the bulk phase and grain boundaries, thereby restricting the performance and stabil

As a promising photovoltaic material, metal halide perovskite yields high efficiency in solar cells. However, the deep-level traps of minority carriers at the surface of the p-i-n perovskite solar cells can suppress nonradiative recombination, so the precise passivation of deep-level traps has been the major focus in raising the power conversion efficiency (PCE) to the theoretical Shockley-Queis

China has carried out an in-orbit test of its domestically developed space-based fuel cell, according to the China Academy of Space Technology. The academy, part of China Aerospace Science and Technology Corp, said the cell worked well in environments characterized by vacuums, extreme low temperature and microgravity during the test that took place recently outside the Tianzhou 5 cargo spaceship

London (AFP) Nov 28, 2022
Britain on Monday unveiled an energy-saving campaign to encourage lower consumption this winter - a policy U-turn - and increased financial help for home insulation. Prime Minister Rishi Sunak's Conservative government announced the publicity blitz just two months after his short-lived predecessor, Liz Truss, ruled out such a move and ran into immediate criticism from opposition politician

The United Nations warned Tuesday that carbon emissions from shipping were growing, calling on the vast industry to scrap old, polluting vessels and upgrade infrastructure to speed up its green transition. The UN's trade and development agency UNCTAD highlighted the vital role shipping plays in the global economy, with over 80 percent of all traded goods in the world moved by sea. But wh

Owners of electric vehicles (EVs) are accustomed to plugging into charging stations at home and at work and filling up their batteries with electricity from the power grid. But someday soon, when these drivers plug in, their cars will also have the capacity to reverse the flow and send electrons back to the grid. As the number of EVs climbs, the fleet's batteries could serve as a cost-effective,

UCLA researchers and their colleagues have discovered a new physics principle governing how heat transfers through materials, and the finding contradicts the conventional wisdom that heat always moves faster as pressure increases. Up until now, the common belief has held true in recorded observations and scientific experiments involving different materials such as gases, liquids and solids

Seoul, South Korea (SPX) Nov 24, 2022
Dabeeo, a geospatial information technology company based on AI (CEO: Ju-hum Park), has announced a partnership with Maxar Technology ("Maxar" hereinafter), a leading space technology and intelligence company. This partnership enables Dabeeo to expand its domestic and international earth observation service business. The satellite data analysis market is expanding rapidly in line with the

The cutting edge of additive manufacturing offers a world of possibilities for companies looking to transform their manufacturing processes and create new products. But companies that want to tap into that world have traditionally had to invest huge sums of money into the latest 3D printing machines and then figure out how to integrate them into their operations. That's a tough sell consid

In a scene from "Star Wars: Episode IV - A New Hope," R2D2 projects a three-dimensional hologram of Princess Leia making a desperate plea for help. That scene, filmed more than 45 years ago, involved a bit of movie magic - even today, we don't have the technology to create such realistic and dynamic holograms. Generating a freestanding 3D hologram would require extremely precise and fast c

Researchers affiliated with the Q-NEXT quantum research center show how to create quantum-entangled networks of atomic clocks and accelerometers - and they demonstrate the setup's superior, high-precision performance. For the first time, scientists have entangled atoms for use as networked quantum sensors, specifically, atomic clocks and accelerometers. The research team's experiment

A 'simple' tweak to perovskite solar cells during the fabrication stage could help to unlock the untold potential of the renewable energy source, claims research from the University of Surrey. Surrey's Advanced Technology Institute (ATI) has demonstrated that by precisely controlling the fabrication process, it is possible to regulate and reduce unwanted energy loss in perovskite solar pan

China on Tuesday launched the Shenzhou-15 spacecraft carrying three astronauts to its space station, where they will complete the country's first-ever crew handover in orbit, state news agency Xinhua reported. The trio blasted off in a Long March-2F rocket at 11:08 pm (1508 GMT) from the Jiuquan launch centre in northwestern China's Gobi desert, Xinhua said, citing the China Manned Space Administration (CMSA)

On November 30, 2022, Twitter said it would no longer implement its COVID-19 Misleading Information Policy.  That means the platform would not take down messages that contained “demonstrably false or potentially misleading content.” Twitter would not mark or annotate such information either. As a result, the platform would no longer suspend accounts that repeatedly break […]

A deepfake video of Mark Zuckerberg praising Congress for its inaction on tech antitrust legislation is creating waves after its debut in an ad Tuesday.

In what is now a familiar refrain in Chicago, residents told alarming stories Tuesday to a federal judge about what they described as racist and traumatic encounters with Chicago police officers.

Amid Elon Musk's measures to protect free speech on Twitter, including the elimination of its COVID "misinformation policy," the White House is promising to keep "a close eye" on the social media platform. The new Twitter owner made it clear he believes the stakes are high. "This is a battle for the future of civilization.…
