🗞 TECHNOLOGY NEWS💻🔧🖥:

NANOSCALE SCHOTTKY DIODES FABRICATED VIA ADHESION LITHOGRAPHY

To fabricate nanoscale photonic and electronic devices, engineers need electrodes made of asymmetric metals separated by gaps in the nanometer (nm) length scale. So far, most of these electrodes were fabricated using high-end patterning techniques, such as electron-beam lithography.

VISION-BASED FIRE DETECTION FACILITIES WORK BETTER UNDER NEW DEEP LEARNING MODEL

Fast and accurate fire detection is significant to the sustainable development of human society and Earth ecology. The existence of objects with similar characteristics to fire increases the difficulty of vision-based fire detection. Improving the accuracy of fire detection by digging deeper visual features of fire always remains challenging.

MICRO-ROBOT WITH CHEMICALLY ENCODED INTELLIGENCE REMOVES HORMONAL POLLUTANTS

A team of researchers from the University of Chemistry and Technology Prague, Yonsei University and the Brno University of Technology has developed a micro-robot with chemically encoded intelligence that can remove hormonal pollutants from a solution. They have published their results in Nature Machine Intelligence. Dongdong Jin and Li Zhang with the Chinese University of Hong Kong and Multiscale Medical Robotics Center, respectively, have published a News and Views piece in the same issue outlining the state of micro-robot research and describe the work done by the researchers with this new effort

🗞 PHYSICS NEWS⚙♨:

TOPOLOGICAL MECHANICAL METAMATERIALS GO BEYOND NEWTON’S THIRD LAW

A change in perspective can work wonders. This has been especially true with respect to the paradigms for explaining material properties using the concept of topology, “ideas that are currently revolutionizing condensed matter physics,” according to Tel Aviv University researcher Roni Ilan. While topological physics first emerged in condensed matter physics, the ideas have now spread into many other areas, including optics and photonics, as well as acoustics and other mechanical systems, where things have been getting a little tricky.

GOING BEYOND THE ANTI-LASER MAY ENABLE LONG-RANGE WIRELESS POWER TRANSFER

Ever since Nikola Tesla spewed electricity in all directions with his coil back in 1891, scientists have been thinking up ways to send electrical power through the air. The dream is to charge your phone or laptop, or maybe even a healthcare device such as a pacemaker, without the need for wires and plugs. The tricky bit is getting the electricity to find its intended target, and getting that target to absorb the electricity instead of just reflect it back into the air—all preferably without endangering anyone along the way.

RESEARCH TEAM PUSHES BACK THE BOUNDARIES OF HIGH-ENERGY LASER PULSES

Using the Advanced Laser Light Source (ALLS) facility, the research team of Professor François Légaré of the Institut national de la recherche scientifique (INRS) has pushed back the boundaries of high-energy pulse propagation in a nonlinear medium through the observation of high-energy multidimensional solitary states. This breakthrough allows the direct generation of extremely short and intense, laser pulses that are highly-stable in time and space. The results of this work were published in Nature Photonics.

🗞 EARTH NEWS🌏:

SYNTHESIS STUDY DEMONSTRATES PHYTOPLANKTON CAN BLOOM BELOW ARCTIC SEA ICE

Small photosynthetic marine algae are a key component of the Arctic marine ecosystem but their role for the ecology of the Arctic Ocean have been underestimated for decades. That’s the conclusion of a team of scientists who synthesized more than half a century of research about the occurrence, magnitude and composition of phytoplankton blooms under Arctic sea ice. The results were published in a special issue of Frontiers in Marine Science devoted to Arctic Ocean research.

‘OASIS EFFECT’ IN URBAN PARKS COULD CONTRIBUTE TO GREENHOUSE GAS EMISSIONS, STUDY FINDS

It will come as no surprise to anyone living in Phoenix, Arizona, that 2020 has been a record-breaking year for high temperatures. According to the National Weather Service, in 2020 the Phoenix area has surpassed all previous years for average high temperatures and excessive heat warnings.

SOME GLACIERS IN THE TETONS FOUND TO HAVE SURVIVED THE EARLY HOLOCENE WARMING

A trio of researchers, two with Occidental College, the other with the University of Colorado, has found evidence that some of the glaciers in the Tetons survived the early Holocene warming. In their paper published in the journal Science Advances, Darren Larsen, Sarah Crump and Aria Blumm describe their study of ice core samples taken from two sites in the Tetons.

🗞 ASTRONOMY & SPACE NEWS🌪🎇:

MACHINE LEARNING YIELDS A BREAKTHROUGH IN THE STUDY OF STELLAR NURSERIES

Artificial intelligence can make it possible to see astrophysical phenomena that were previously beyond reach. This has now been demonstrated by scientists from the CNRS, IRAM, Observatoire de Paris-PSL, Ecole Centrale Marseille and Ecole Centrale Lille, working together in the ORION-B program. In a series of three papers published in Astronomy & Astrophysics on 19 November 2020, they present the most comprehensive observations yet carried out of one of the star-forming regions closest to the Earth.

HUGE PUERTO RICO RADIO TELESCOPE TO CLOSE IN BLOW TO SCIENCE

The National Science Foundation announced Thursday that it will close the huge telescope at the renowned Arecibo Observatory in Puerto Rico in a blow to scientists worldwide who depend on it to search for planets, asteroids and extraterrestrial life.

SKY SURVEY REVEALS NEWBORN JETS IN DISTANT GALAXIES

Astronomers using data from the ongoing VLA Sky Survey (VLASS) have found a number of distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material within the past two decades or so. The scientists compared data from VLASS with data from an earlier survey that also used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to reach their conclusion.

🗞 NANOTECHNOLOGY NEWS⛄☃:

AN IMPERCEPTIBLE THIN-FILM SENSOR TO RECORD MOVEMENT AND THE SENSE OF TOUCH

Researchers have developed an ultrathin pressure sensor that can be attached directly to the skin and measure how fingers interact with objects to produce useful data for medical and technological applications. The sensor has minimal effect on the users’ sensitivity and ability to grip objects, and it is resistant to disruption from rubbing. The team also hopes their sensor can be used for the novel task of digitally archiving the skills of craft workers.

PREDICTING FORCES BETWEEN ODDLY SHAPED NANOPARTICLES

Materials scientists at Duke University have devised a simplified method for calculating the attractive forces that cause nanoparticles to self-assemble into larger structures.

SCIENTISTS PROPOSE MACHINE LEARNING METHOD FOR 2-D MATERIAL SPECTROSCOPY

Machine learning is an important branch in the field of artificial intelligence. Its basic idea is to build a statistical model based on data and use the model to analyze and predict the data. With the rapid development of big data technology, data-driven machine learning algorithms have begun to flourish in various fields of materials research.
