🗞 TECHNOLOGY NEWS💻🔧🖥:
EFFICIENT LIGHT-EMITTING DIODES MADE BY DEPOSITING PEROVSKITES ON A FLUORIDE INTERFACE
Light-emitting diodes (LEDs) are devices that emit light when electrical current flows through them, traditionally fabricated using semiconducting materials. Over the past few years, scientists and electronics engineers have been exploring the potential of LEDs made of perovskites, a class of materials often used to create photovoltaic (PV) technology with many possible compositions and numerous potential properties, such as superconductivity and magnetoresistance.
SOFTWARE DEVELOPED TO HELP PROGRAMMERS PROTOTYPE GRAPHIC USER INTERFACES
A new artificial intelligence (AI) system has been developed to help ordinary untrained people to design and create applications and software for smartphones and personal computers. With the help of this system, non-designers can quickly and easily create a user-friendly mobile app.
INVENTION LETS ROTTING VEGGIES MAKE A GREENER WORLD
For generations, kids have been coaxed into finishing their vegetables after their parents sternly advised them that it is not nice to waste food when people are starving elsewhere in the world. But someday soon, kids may have a comeback: “If we eat those vegetables, we can’t help fight climate change, reduce the carbon footprint or help provide power to underserved regions of our world.”
🗞 PHYSICS NEWS⚙♨:
SEARCHING FOR AXION DARK MATTER CONVERSION SIGNALS IN THE MAGNETIC FIELDS AROUND NEUTRON STARS
According to theoretical predictions, axion dark matter could be converted into radio frequency electromagnetic radiation when it approaches the strong magnetic fields that surround neutron stars. This radio signature, which would be characterized by an ultranarrow spectral peak at a frequency that depends on the mass of the axion dark matter particle in question, could be detected using high-precision astronomical instruments.
‘SEARCH OF A LIFETIME’ FOR SUPERSYMMETRIC PARTICLES AT CERN
A team of researchers at the University of Chicago recently embarked on the search of a lifetime—or rather, a search for the lifetime of long-lived supersymmetric particles.
STUDY OF POLYCYCLIC AROMA SHOWS MOLECULES FOLLOWING SAME RELAXATION PATHWAY AND BEHAVING MORE LIKE SOLIDS THAN MOLECULES
A team of researchers from Institut Lumière Matière, Universität Heidelberg and Leiden University has found via study of a whole class of polycyclic aromatic hydrocarbons (PAHs) that such molecules follow the same relaxation pathways and have size-dependent lifetimes—and behave more like solids than is typical for molecules. In their paper published in the journal Nature Physics, the group describes their work, which involved studying what happens when ultrashort X-rays are fired at large and complex molecules. Laura Cattaneo with the Max Planck Institute for Nuclear Physics has written a News and Views piece outlining general work involved in trying to understand photochemistry in complex big molecules and the work done by the team on this new effort.
🗞 EARTH NEWS🌏:
THERE ARE MICROPLASTICS NEAR THE TOP OF MOUNT EVEREST TOO
Researchers analyzing snow and stream samples from the National Geographic and Rolex Perpetual Planet Everest Expedition have found evidence of microplastic pollution on Mount Everest. While the highest concentrations of microplastics were around Base Camp where hikers and trekkers spend the most time, the team also found microplastics as high up as 8,440 meters above sea level, just below the summit. The findings appear November 20 in the journal One Earth.
RESEARCHERS DISCOVER ‘MISSING’ PIECE OF HAWAII’S FORMATION
An oceanic plateau has been observed for the first time in the Earth’s lower mantle, 800 kilometers deep underneath Eastern Siberia, pushing Hawaii’s birthplace back to 100 million years, says a Michigan State University geophysicist.
SOME AMAZON RAINFOREST REGIONS MORE RESISTANT TO CLIMATE CHANGE THAN PREVIOUSLY THOUGHT
Forests can help mitigate climate change, by taking in carbon dioxide during photosynthesis and storing it in their biomass (tree trunks, roots, etc.). In fact, forests currently take in around 25-30% of our human-generated carbon dioxide (CO2) emissions. Certain rainforest regions, such as the Amazon, store more carbon in their biomass than any other ecosystem or forest but when forests become water-stressed (not enough water in the soil, and/or air is extremely dry), forests will slow down or stop photosynthesis. This leaves more CO2 in the atmosphere, and can also lead to tree mortality.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
UNDERSTANDING THE ‘DARK’ UNIVERSE AND PRIMORDIAL GALAXY FORMATION
Visible matter constitutes only 16% of the universe’s total mass. Little is known about the nature of the rest of that mass, which referred to as dark matter. Even more surprising is the fact that the universe’s total mass accounts for only 30% of its energy. The rest is dark energy, which is totally unknown but is responsible for the universe’s accelerated expansion.
RESOLVING LONG-STANDING MYSTERIES ABOUT THE FIRST PARALLAXES IN ASTRONOMY
In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax—setting the first scale of the universe.
IN DECEMBER, JUPITER, SATURN WILL LOOK LIKE DOUBLE PLANET FOR FIRST TIME SINCE THE MIDDLE AGES
Just after sunset on the evening of Dec. 21, Jupiter and Saturn will appear closer together in Earth’s night sky than they have been since the Middle Ages, offering people the world over a celestial treat to ring in the winter solstice.
🗞 NANOTECHNOLOGY NEWS⛄☃:
NANOBUBBLE-CONTROLLED NANOFLUIDIC TRANSPORT
Nanofluidic platforms can offer tunable material transport for biosensing, chemical detection and filtration. Research in the past had achieved elective and controlled ion transport based on electrical, optical and chemical gating methods of complex nanostructures. In a new report now published in Science Advances, Jake Rabinowitz and a team of researchers in electrical engineering, biological sciences and biomedical engineering at the Columbia University, New York, U.S., mechanically controlled nanofluidic transport using nanobubbles. They mechanically generated the nanobubbles made stable via surface pinning and verified them using cryogenic transmission electron microscopy techniques. The findings are relevant for nanofluidic device engineering and nanopipette-based applications.
STAYING AHEAD OF THE CURVE WITH 3-D CURVED GRAPHENE
A team of researchers has amplified 3-D graphene’s electrical properties by controlling its curvature.
ENHANCING QUANTUM DOT SOLAR CELL EFFICIENCY TO 11.53%
A novel technology that can improve the efficiency of quantum dot solar cells to 11.53% has been unveiled. Published in the February 2020 issue of Advanced Energy Materials, it has been evaluated as a study that solved the challenges posed by the generation of electric currents from sunlight by solar cells by enhancing the hole extraction.
