Published Harnessing green energy from plants depends on their circadian rhythms
(via sciencedaily.com) Original source Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent, cyclic voltage creation could be harnessed as an energy source.
Published Apple versus donut: How the shape of a tokamak impacts the limits of the edge of the plasma
(via sciencedaily.com) Original source A new model for ballooning instabilities in apple-shaped fusion vessels considers the height and width of the plasma's edge.
Published Charge your laptop in a minute or your EV in 10? Supercapacitors can help
(via sciencedaily.com) Original source Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes. New research could lead to such advances.
Published Theory and experiment combine to shine a new light on proton spin
(via sciencedaily.com) Original source Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a new method that combines experimental data with state-of-the-art calculations has revealed a more detailed picture of spin contributions from the very glue that holds protons together.
Published Controlling water, transforming greenhouse gases
(via sciencedaily.com) Original source Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
Published More than spins: Exploring uncharted territory in quantum devices
(via sciencedaily.com) Original source Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the '0' and the '1'. However, spins in real devices also interact with light and vibrations known as bosons, greatly complicating calculations. Researchers now demonstrate a way to describe spin-boson systems and use this to efficiently configure quantum devices in a desired state.
Published How a tiny device could lead to big physics discoveries and better lasers
(via sciencedaily.com) Original source Researchers have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings could also support the development of more efficient lasers, which are used in fields ranging from medicine to manufacturing.
Published Renewable grid: Recovering electricity from heat storage hits 44% efficiency
(via sciencedaily.com) Original source Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to new research.
Published Electromechanical material doesn't get 'clamped' down
(via sciencedaily.com) Original source A new study finds that a class of electromechanically active materials called antiferroelectrics may hold the key to overcoming performance limitations due to clamping in miniaturized electromechanical systems.
Published Charting a pathway to next-gen biofuels
(via sciencedaily.com) Original source From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds
(via sciencedaily.com) Original source Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published Shedding light on the chemical enigma of sulfur trioxide in the atmosphere
(via sciencedaily.com) Original source Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.
Published New discoveries about the nature of light could improve methods for heating fusion plasma
(via sciencedaily.com) Original source Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy.
Published Cement recycling method could help solve one of the world's biggest climate challenges
(via sciencedaily.com) Original source Researchers have developed a method to produce very low emission concrete at scale -- an innovation that could be transformative in the transition to net zero. The method, which the researchers say is 'an absolute miracle', uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, the carbon-hungry component of concrete.
Published Strings that can vibrate forever (kind of)
(via sciencedaily.com) Original source Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.
