NEW 2-D RUDDLESDEN-POPPER (RP) LAYERED PEROVSKITE-BASED SOLAR CELLS
In recent years, researchers worldwide have been trying to develop solar cells and other technologies that can produce electrical energy from renewable sources, as these could reduce the emission of greenhouse gases and thus help to preserve life on our planet. Solar cells can be built using a variety of materials, including silicon, copper or other semiconductors.
SCIENTISTS PUBLISH OPEN RESOURCE TO HELP DESIGN ‘GREENER’ ENERGY SYSTEMS
Researchers have created a database of measurements from existing global power grid systems that will help develop new power systems capable of meeting changing demands, such as the move towards renewable energy sources.
ARTIFICIAL VISUAL SYSTEM OF RECORD-LOW ENERGY CONSUMPTION FOR THE NEXT GENERATION OF AI
A joint study led by City University of Hong Kong (CityU) has built an ultralow-power consumption artificial visual system to mimic the human brain, which successfully performed data-intensive cognitive tasks. Their experiment results could provide a promising device system for the next generation of artificial intelligence (AI) applications.

NEAR-ATOMIC-SCALE ANALYSIS OF FROZEN WATER
Advances in transmission electron microscopy (TEM) can allow cryo-imaging of biological and biochemical systems in liquid form, however, such approaches do not possess advanced analytical capabilities. In a new report now published on Science Advances, A. A. El-Zoka and an international team of researchers in Germany, Canada, France, and the U.K., used atom probe tomography to analyze frozen liquids in three-dimensions (3-D) with sub-nanometer scale resolution. In this work, the team first introduced a specimen preparation strategy using nano-porous gold and used ice formed from high-purity deuterated water (hard water) alongside a solution of sodium chloride (50 mM) dissolved in high-purity deuterated water. They then analyzed the gold-ice interface to reveal increased solute concentrations across the interface. The scientists explored a range of experimental conditions to understand atom probe analyses of bulk aqueous specimens. Then they discussed the physical processes associated with the observed phenomena. The study showed the practicality of using frozen water as a carrier for near-atomic-scale analyses of objects in solution via atom probe tomography.
ARTIFICIAL INTELLIGENCE IMPROVES CONTROL OF POWERFUL PLASMA ACCELERATORS
Researchers have used AI to control beams for the next generation of smaller, cheaper accelerators for research, medical and industrial applications.
SCIENTISTS DEMONSTRATE LASER DIRECT MAPPING OF ATTOSECOND ELECTRON DYNAMICS
Recently, a research group from the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences (CAS) has observed periodic electron bunch fringes induced by the femtosecond laser field.

COVID LOCKDOWN CAUSES RECORD DROP IN CO2 EMISSIONS FOR 2020
The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020—a record drop according to researchers at the University of East Anglia (UEA), University of Exeter and the Global Carbon Project.
SOME DROUGHTS DURING THE INDIAN MONSOON ARE DUE TO UNIQUE NORTH ATLANTIC DISTURBANCES
A team of researchers from the Indian Institute of Science and Cotton University has found that some droughts during monsoon season in India are due to unique North Atlantic disturbances. In their paper published in the journal Science, the group describes their study of weather patterns in South Asia over the past century and what it showed about monsoon season droughts.
CLIMATE MODELS OVERESTIMATE NATURAL VARIABILITY
By looking at satellite measurements of temperature changes in the lower layer of Earth’s atmosphere, scientists found that climate models may have overestimated the decade-to-decade natural variability of temperature.

SOLAR ORBITER: TURNING PICTURES INTO PHYSICS
Solar Orbiter’s latest results show that the mission is making the first direct connections between events at the solar surface and what’s happening in interplanetary space around the spacecraft. It is also giving us new insights into solar ‘campfires,” space weather and disintegrating comets.
FESTIVE TREAT FOR STARGAZERS AS GEMINID METEORS PEAK
Stargazers across the northern hemisphere could see as many as 70 meteors an hour this coming Sunday, as the Geminids meteor shower reaches its peak. Prospects for what should be this year’s best display of meteors are particularly good, as there will be no Moon in the sky to interfere with the view.
WINDOW OPENS FOR VIRGIN GALACTIC TEST FLIGHT FROM SPACEPORT
The window opened Friday for Virgin Galactic’s first rocket-powered test flight from Spaceport America in southern New Mexico as the company prepares for commercial flights next year, but the exact timing of the launch will depend on the weather.
