Published Underwater mapping reveals new insights into melting of Antarctica's ice shelves
(via sciencedaily.com) Original source Clues to future sea level rise have been revealed by the first detailed maps of the underside of a floating ice shelf in Antarctica. An international research team deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica.
Published Barriers designed to prevent saltwater intrusion may worsen inland flooding
(via sciencedaily.com) Original source Building protection barriers without accounting for potential inland flooding risks from groundwater can eventually worsen the very issues they aim to solve.
Published More electricity from the sun
(via sciencedaily.com) Original source A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.
Published Physicists use light to probe deeper into the 'invisible' energy states of molecules
(via sciencedaily.com) Original source Physicists have experimentally demonstrates a novel physical effect that was predicted 45 years ago. The effect will result in a new chemical analysis technique, to simultaneously identify molecular bonds and their 3D arrangement in space. This new technique will find applications in pharmaceutical science, security, forensics, environmental science, art conservation, and medicine.
Published Green hydrogen: 'Artificial leaf' becomes better under pressure
(via sciencedaily.com) Original source Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
Published New collaborative research generates lessons for more adaptive lake management
(via sciencedaily.com) Original source A professor gathered feedback from 26 Colorado River Basin managers and experts took on water user roles to discuss consuming, banking and trading Colorado River water.
Published Super-black wood can improve telescopes, optical devices and consumer goods
(via sciencedaily.com) Original source Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
Published Researchers identify unique phenomenon in Kagome metal
(via sciencedaily.com) Original source A new study focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons -- nanoscale-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.
Published What no one has seen before -- simulation of gravitational waves from failing warp drive
(via sciencedaily.com) Original source Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.
Published New more sustainable method for manufacturing microchips and other nanoscale devices
(via sciencedaily.com) Original source Researchers develop a more environmentally friendly approach to manufacturing nano-scale microchip devices using water as a solvent in place of toxic chemicals. The method not only cleans up the manufacturing waste stream, but also enables the integration of electronic and biological components.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published Bold moves needed for California agriculture to adapt to climate change
(via sciencedaily.com) Original source California needs urgent and bold measures to adapt its $59 billion agriculture sector to climate change as the amount of water available for crops declines, according to a new report. The report provides a roadmap for more water capture, storage, and distribution systems that are in harmony with climate projections and ecosystems. It further considers how runoff and groundwater can be used repeatedly as it flows generally from mountainsides to coastal lands.
Published Researchers trap atoms, forcing them to serve as photonic transistors
(via sciencedaily.com) Original source Researchers have developed a means to realize cold-atom integrated nanophotonic circuits.
Published Plant-inspired polymers for water purification
(via sciencedaily.com) Original source Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.
Published Optical fibers fit for the age of quantum computing
(via sciencedaily.com) Original source A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published New study disputes Hunga Tonga volcano's role in 2023-24 global warm-up
(via sciencedaily.com) Original source New research is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the process.
Published Atomic 'GPS' elucidates movement during ultrafast material transitions
(via sciencedaily.com) Original source Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a years-long scientific debate and could facilitate the design of new transitioning materials with commercial applications.
Published Thousands of birds and fish threatened by mining for clean energy transition, study finds
(via sciencedaily.com) Original source Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.
Published Fresh light on the path to net zero
(via sciencedaily.com) Original source Researchers have used magnetic fields to reveal the mystery of how light particles split. Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light photons into small chunks.
Published Shining light on similar crystals reveals photoreactions can differ
(via sciencedaily.com) Original source A research team has revealed that photoreactions proceed differently depending on the crystal structure of photoreactive molecules, shining a light on the mechanism by which non-uniform photoreactions occur within crystals. This is a new step toward controlling photoreactions in crystals.
