Published Researchers achieve historic milestone in energy capacity of supercapacitors



In a new landmark chemistry study, researchers describe how they have achieved the highest level of energy storage -- also known as capacitance -- in a supercapacitor ever recorded.
Published Bifacial perovskite solar cells point to higher efficiency


A bifacial perovskite solar cell, which allows sunlight to reach both sides of the device, holds the potential to produce higher energy yields at lower overall costs.
Published Giant stone artefacts found on rare Ice Age site in Kent, UK



Researchers have discovered some of the largest early prehistoric stone tools in Britain.
Published Don't wait, desalinate: A new approach to water purification



A water purification system separates out salt and other unnecessary particles with an electrified version of dialysis. Successfully applied to wastewater with planned expansion into rivers and seas, the method saves money and saps 90% less energy than its counterparts.
Published Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts



CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.
Published Humans' evolutionary relatives butchered one another 1.45 million years ago



Researchers have identified the oldest decisive evidence of humans' close evolutionary relatives butchering and likely eating one another.
Published Perovskite solar cells set new record for power conversion efficiency



Perovskite solar cells have attained now attained the extremely high efficiency rate of 24.35% with an active area of 1 cm2. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources will be crucial to securing the world's energy future.
Published Breakthrough innovation could solve temperature issues for source-gated transistors and lead to low-cost, flexible displays



Low-cost, flexible displays that use very little energy could be a step closer, thanks to an innovation that solves a problem that has plagued source-gated transistors (SGT).
Published New microcomb device advances photonic technology



Researchers have outlined a new high-speed tunable microcomb that could help propel advances in wireless communication, imaging, atomic clocks, and more.
Published Inside-out heating and ambient wind could make direct air capture cheaper and more efficient



Chemical engineers use coated carbon fibers and eliminate steam-based heating in their simpler design, which also can be powered by wind energy.
Published Vastly more sustainable, cost-effective method to desalinate industrial wastewater



Engineers are developing a cutting-edge process that can reduce energy consumption and cost of water desalination.
Published How tidal range electricity generation could meet future demand and storage problems



Tidal range schemes are financially viable and could lower energy bills say researchers. Research combined a tidal range power generation model with its cost model to demonstrate the viability of tidal power. The research demonstrates the benefits of tidal energy, which does not suffer from unpredictable intermittency as power is generated both day and night, and in windy or calm weather. The creation of a tidal barrage could operate for 120 years or more to meet future demand and storage problems.
Published To boost supply chains, scientists are looking at ways to recover valuable materials from water



Researchers are exploring the different ways of harvesting materials from water.
Published Study shows ancient Alaskans were freshwater fishers



A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.
Published Engineers develop a soft, printable, metal-free electrode



Engineers developed a metal-free, Jelly-like material that is as soft and tough as biological tissue and can conduct electricity similarly to conventional metals. The new material, which is a type of high-performance conducting polymer hydrogel, may one day replace metals in the electrodes of medical devices.
Published Energy harvesting via vibrations: Researchers develop highly durable and efficient device



An international research group has engineered a new energy-generating device by combining piezoelectric composites with carbon fiber-reinforced polymer (CFRP), a commonly used material that is both light and strong. The new device transforms vibrations from the surrounding environment into electricity, providing an efficient and reliable means for self-powered sensors.
Published Metaverse could put a dent in global warming



For many technology enthusiasts, the metaverse has the potential to transform almost every facet of human life, from work to education to entertainment. Now, new research shows it could have environmental benefits, too.
Published Remains at Crenshaw site are local, ancestors of Caddo



Hundreds of human skulls and mandibles recovered from the Crenshaw site in southwest Arkansas are the remains of ancestors of the Caddo Nation and not foreign enemies, according to a new study.
Published All-electric rideshare fleet could reduce carbon emissions, increase traffic issues



Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
Published Novel ferroelectrics for more efficient microelectronics



A team of researchers is exploring novel materials that have potential to make microelectronics more energy efficient. Their recent work explores recently discovered wurtzite ferroelectrics, which are mainly composed of materials that are already incorporated in semiconductor technology for integrated circuits. These materials allow for the integration of new power-efficient devices for applications such as non-volatile memory, electro-optics, and energy harvesting.
