Published More efficient bioethanol production might be possible using persimmon tannin to help yeast thrive



Researchers have found that persimmon tannin, known for its antioxidant properties, improves the growth of yeast in the presence of ethanol.
Published Wind farms can offset their emissions within two years



After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.
Published Carbon-capture batteries developed to store renewable energy, help climate



Researchers are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide. Researchers recently created and tested two different formulations for batteries that store renewable energy; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products.
Published Copper can't be mined fast enough to electrify the US



Copper cannot be mined quickly enough to keep up with current U.S. policy guidelines to transition the country's electricity and vehicle infrastructure to renewable energy, according to a new study.
Published Making batteries takes a lot of lithium: Some could come from gas well wastewater



A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Published Using AI to improve building energy use and comfort



Researchers have developed a new method that can lead to significant energy savings in buildings. The team identified 28 major heat loss regions in a multi-unit residential building with the most severe ones being at wall intersections and around windows. A potential energy savings of 25 per cent is expected if 70 per cent of the discovered regions are fixed.
Published Metalens expands Its reach from light to sound



Engineers achieve a wide field-of-hearing acoustic metalens free from aberrations.
Published Eco-friendly and affordable battery for low-income countries



A battery made from zinc and lignin that can be used over 8000 times. This has been developed with a vision to provide a cheap and sustainable battery solution for countries where access to electricity is limited.
Published Exceptionally large transverse thermoelectric effect produced by combining thermoelectric and magnetic materials



A research team has demonstrated that a simple stack of thermoelectric and magnetic material layers can exhibit a substantially larger transverse thermoelectric effect -- energy conversion between electric and heat currents that flow orthogonally to each other within it -- than existing magnetic materials capable of exhibiting the anomalous Nernst effect. This mechanism may be used to develop new types of thermoelectric devices useful in energy harvesting and heat flux sensing.
Published Hide and seek between atoms: Find the dopant



Collaborative efforts decode the mechanism behind stabilizing cathode doping in electric vehicle batteries.
Published Transforming common soft magnets into a next-generation thermoelectric conversion materials by 3 minutes heat treatment



A research team has demonstrated that an iron-based amorphous alloy, widely used as a soft magnetic material in transformers and motors, can be transformed into a 'transverse' thermoelectric conversion material that converts electric and thermal currents in orthogonal directions, with just a short period of heat treatment. This is the first example that highlights the importance of microstructure engineering in the development of transverse thermoelectric conversion materials, and provides new design guidelines for materials development to realize environmentally friendly power generation and thermal management technologies using magnetic materials.
Published Disorder improves battery life



What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team has discovered that local disorder in the oxide cathode material increases the number of times Li-ion batteries can be charged and discharged.
Published Efficacy of solar panels boosted



Solar energy is a crucial asset in the fight against climate change, and researchers have now devised a smart approach to optimize its effectiveness. Their innovative method includes incorporating artificial ground reflectors, a simple yet powerful enhancement.
Published Cost-effective, high-capacity, and cyclable lithium-ion battery cathodes



Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.
Published Innovation promises to prevent power pole-top fires



Engineers in Australia have found a new way to make power-pole insulators resistant to fire and electrical sparking, promising to prevent dangerous pole-top fires and reduce blackouts. Pole-top fires pose significant challenges to power providers and communities worldwide. In March, pole-top fires cut power from 40,000 homes and businesses in Perth, Australia. The 2020 Royal Commission into National Natural Disaster Arrangements found that power outages experienced by 280,000 customers from various energy providers during Black Summer fires in Australia were mainly triggered by events involving insulators and poles.
Published Physicists show that light can generate electricity even in translucent materials



Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.
Published Energy trades could help resolve Nile conflict



Scientists have shed light on a new, transformative approach that could help resolve a dispute over the Nile river's water resources.
Published Scientists capture X-rays from upward positive lightning



Researchers have for the first time recorded X-rays being produced at the beginning of upward positive lightning flashes; an observation that gives important insight into the origins of this rare -- and particularly dangerous -- form of lightning.
Published Robotic nerve 'cuffs' could help treat a range of neurological conditions



Researchers have developed tiny, flexible devices that can wrap around individual nerve fibers without damaging them. The researchers combined flexible electronics and soft robotics techniques to develop the devices, which could be used for the diagnosis and treatment of a range of disorders, including epilepsy and chronic pain, or the control of prosthetic limbs.
Published New offshore wind turbines can take away energy from existing ones



Interactions between wind turbines could reduce power output by 30% in proposed offshore wind farm areas along the East Coast, new research has found. In all, the farms could still meet 60% of the electricity demand of New England.
