Published Unique field study shows how climate change affects fire-impacted forests
(via sciencedaily.com) Original source During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published Researchers shine light on rapid changes in Arctic and boreal ecosystems
(via sciencedaily.com) Original source Arctic and boreal latitudes are warming faster than any other region on Earth.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com) Original source By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Fires pose growing worldwide threat to wildland-urban interface
(via sciencedaily.com) Original source Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.
Published Cooler transformers could help electric grid
(via sciencedaily.com) Original source Simulations on the Stampede2 supercomputer of the Texas Advanced Computing Center (TACC) are helping scientists engineer solutions to overheating of grid transformers -- a critical component of the electric grid.
Published Global North energy outsourcing demands more attention
(via sciencedaily.com) Original source Manufacturing nations in the Global North are stockpiling energy and emission problems by outsourcing energy-intensive industrial processes to countries in the Global South.
Published Quantum precision: A new kind of resistor
(via sciencedaily.com) Original source Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect.
Published Pyrite, also known as fool's gold, may contain valuable lithium, a key element for green energy
(via sciencedaily.com) Original source The technology revolution and development of new renewable energy resources is driving demand for lithium to new heights, but it is not a common mineral. Scientists say they have found lithium in an unexpected place; fool's gold, or pyrite, deposits.
Published With inspiration from 'Tetris,' researchers develop a better radiation detector
(via sciencedaily.com) Original source A new detector system based on the game 'Tetris' could enable inexpensive, accurate radiation detectors for monitoring nuclear sites.
Published New device gathers, stores electricity in remote settings
(via sciencedaily.com) Original source Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
Published BESSY II: How pulsed charging enhances the service time of batteries
(via sciencedaily.com) Original source An improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces aging effects, an international team demonstrated.
Published New four-terminal tandem organic solar cell achieves 16.94% power conversion efficiency
(via sciencedaily.com) Original source Researchers have fabricated a new four-terminal organic solar cell with a tandem configuration with a 16.94% power conversion efficiency (PCE). The new device is composed by a highly transparent front cell that incorporates a transparent ultrathin silver (Ag) electrode of only 7nm, which ensures its efficient operation.
Published Using pulp and paper waste to scrub carbon from emissions
(via sciencedaily.com) Original source Researchers have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production. The technique they've pioneered not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.
Published 'Tug of war' tactic enhances chemical separations for critical materials
(via sciencedaily.com) Original source Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.
Published Drawing inspiration from plants: A metal-air paper battery for wearable devices
(via sciencedaily.com) Original source Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.
Published Magnetic fields boost clean energy
(via sciencedaily.com) Original source Researchers show that using magnetic fields can boost electrocatalysis for sustainable fuel production by enhancing the movement of the reactants, which improves the efficiency of energy-related reactions.
Published A simple way to harvest more 'blue energy' from waves
(via sciencedaily.com) Original source As any surfer will tell you, waves pack a powerful punch. Now, we are one step closer to capturing the energy behind the ocean's constant ebb and flow with an improved 'blue energy' harvesting device. Researchers report that simply repositioning the electrode -- from the center of a see-sawing liquid-filled tube to the end where the water crashes with the most force -- dramatically increased the amount of wave energy that could be harvested.
Published Building blocks for greener energy: Reconfigurable elastic metasurface
(via sciencedaily.com) Original source Energy harvesting, an eco-friendly technology, extends beyond solar and wind power in generating electricity from unused or discarded energy in daily life, including vibrations generated by passing car engines or trains. Recent intriguing research has been announced, aiming to enhance the efficiency of energy harvesting using a new type of metasurface that can be reconfigured, resembling the assembly of LEGO bricks.
Published Chemistry researchers modify solar technology to produce a less harmful greenhouse gas
(via sciencedaily.com) Original source Researchers are using semiconductors to harvest and convert the sun's energy into high-energy compounds that have the potential to produce environmentally-friendly fuels.
Published Researchers discover dual topological phases in an intrinsic monolayer crystal
(via sciencedaily.com) Original source An international team working with single-atom thick crystals found TaIrTe4's transition between the two distinct topological states of insulation and conduction. The material exhibited zero electrical conductivity within its interior, while its boundaries remain conductive. The team's investigation determined that the two topological states stem from disparate origins. The novel properties can serve as a promising platform for exploring exotic quantum phases and electromagnetism.
