Published New priming method improves battery life, efficiency
(via sciencedaily.com) Original source Engineers have developed a readily scalable method to optimize a silicon anode priming method that increases lithium-ion battery performance by 22% to 44%.
Published Metal-filtering sponge removes lead from water
(via sciencedaily.com) Original source Engineers have developed a new sponge that can remove metals -- including toxic heavy metals like lead and critical metals like cobalt -- from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly contaminated sample of tap water, containing more than 1 part per million of lead. With one use, the sponge filtered lead to below detectable levels.
Published Milk reaction inspires new way to make highly conductive gel films
(via sciencedaily.com) Original source A research team has developed what they call a 'dip-and-peel' strategy for simple and rapid fabrication of two-dimensional ionogel membranes. By dipping sustainable biomass materials in certain solvents, molecules naturally respond by arranging themselves into functional thin films at the edge of the material that can easily be removed using nothing more than a simple set of tweezers.
Published A better route to benzocyclobutenes, sought-after buildingblocks for drugs
(via sciencedaily.com) Original source Chemists devise a new, C-H activation-based method for the synthesis of BCBs.
Published Unlocking the power of photosynthesis for clean energy production
(via sciencedaily.com) Original source Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.
Published Preserving pine forests by understanding beetle flight
(via sciencedaily.com) Original source Researchers study the flight performance of the mountain pine beetle from a fluid mechanics and an entomological perspective. Understanding these aspects of the insect's flight could improve estimates of its spread through the environment and preserve pine forests. To examine insect flight, the team employed a type of model previously used for idealized airfoils. They showed that it can be successfully applied to multiple individual animals across biological sex, insect age, and body size. In doing so, the model can predict how these factors impact flight characteristics.
Published Beetles and their biodiversity in dead wood
(via sciencedaily.com) Original source Which energy type promotes the biodiversity of beetles living in dead wood in the forest? That depends entirely on where the beetles are in the food chain.
Published Exploring the underground connections between trees
(via sciencedaily.com) Original source Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
Published Scintillating science: Researchers improve materials for radiation detection and imaging technology
(via sciencedaily.com) Original source A team of researchers has improved a new generation of organic-inorganic hybrid materials that can improve image quality in X-ray machines, CT scans and other radiation detection and imaging technologies.
Published Tiny microbes could brew big benefits for green biomanufacturing
(via sciencedaily.com) Original source Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals. A research team has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.
Published Researchers develop an additive to efficiently improve the efficiency and stability of perovskite solar cells
(via sciencedaily.com) Original source Perovskite solar cells (PVSCs) are a promising alternative to traditional silicon-based solar cells because of their high power-conversion efficiency and low cost. However, one of the major challenges in their development has been achieving long-term stability. Recently, a research team made a breakthrough by developing an innovative multifunctional and non-volatile additive which can improve the efficiency and stability of perovskite solar cells by modulating perovskite film growth. This simple and effective strategy has great potential for facilitating the commercialization of PVSCs.
Published Scientists find link between photosynthesis and 'fifth state of matter'
(via sciencedaily.com) Original source A new study has found links at the atomic level between photosynthesis and exciton condensates -- a strange state of physics that allows energy to flow frictionlessly through a material. The finding is scientifically intriguing and may suggest new ways to think about designing electronics, the authors said.
Published 'Gluing' soft materials without glue
(via sciencedaily.com) Original source If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.
Published Self-folding origami machines powered by chemical reaction
(via sciencedaily.com) Original source Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Better understanding soft material behavior
(via sciencedaily.com) Original source The mechanics behind the collapse of soft materials structure have befuddled researchers for decades. In a new study, researchers uncover a metric that finally correlates microscopic-level processes with what is seen at the macroscopic level.
Published Previously unknown intercellular electricity may power biology
(via sciencedaily.com) Original source Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
Published Mushrooms and their post-rain, electrical conversations
(via sciencedaily.com) Original source Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.
Published Engineers 'grow' atomically thin transistors on top of computer chips
(via sciencedaily.com) Original source A new method enables 2D-material semiconductor transistors to be directly integrated onto a fully fabricated 8-inch silicon wafer, which could enable a new generation of transistor technology, denser device integration, new circuit architectures, and more powerful chips.
