Published Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts
(via sciencedaily.com) Original source 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 Surprise! Weaker bonds can make polymers stronger
(via sciencedaily.com) Original source Chemists discovered a new way to make polymers stronger: introduce a few weaker bonds into the material. Working with polyacrylate elastomers, they could increase the materials' resistance to tearing up to tenfold by using a weaker type of crosslinker to join some of the polymer building blocks.
Published Making the most of minuscule metal mandalas
(via sciencedaily.com) Original source To unveil the previously elusive behavior and stability of complex metal compounds found in aqueous solutions called 'POMs', researchers have created a speciation atlas. This achievement has the potential to drive new discoveries and advancements in fields like catalysis, medicine, and beyond.
Published Perovskite solar cells set new record for power conversion efficiency
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source Researchers have outlined a new high-speed tunable microcomb that could help propel advances in wireless communication, imaging, atomic clocks, and more.
Published Rain gardens could save salmon from toxic tire chemicals
(via sciencedaily.com) Original source Specially designed gardens could reduce the amount of a toxic chemical associated with tires entering our waterways by more than 90 per cent, new research shows.
Published Inside-out heating and ambient wind could make direct air capture cheaper and more efficient
(via sciencedaily.com) Original source Chemical engineers use coated carbon fibers and eliminate steam-based heating in their simpler design, which also can be powered by wind energy.
Published Biodegradable gel shows promise for cartilage regeneration
(via sciencedaily.com) Original source A gel that combines both stiffness and toughness is a step forward in the bid to create biodegradable implants for joint injuries, according to new research. Mimicking articular cartilage, found in our knee and hip joints, is challenging. This cartilage is key to smooth joint movement, and damage to it can cause pain, reduce function, and lead to arthritis. One potential solution is to implant artificial scaffolds made of proteins that help the cartilage regenerate itself as the scaffold biodegrades. How well the cartilage regenerates is linked to how well a scaffold can mimic the biological properties of cartilage, and to date, researchers have struggled to combine the seemingly incompatible properties of stiffness and toughness. Now, new research outlines a method to marry these properties in a biodegradable gel.
Published Vastly more sustainable, cost-effective method to desalinate industrial wastewater
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
Published To boost supply chains, scientists are looking at ways to recover valuable materials from water
(via sciencedaily.com) Original source Researchers are exploring the different ways of harvesting materials from water.
Published Engineers develop a soft, printable, metal-free electrode
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Nanomaterials: 3D printing of glass without sintering
(via sciencedaily.com) Original source A new process enables printing of nanometer-scale quartz glass structures directly onto semiconductor chips. A hybrid organic-inorganic polymer resin is used as feedstock material for 3D printing of silicon dioxide. Since the process works without sintering, the required temperatures are significantly lower. Simultaneously, increased resolution enables visible-light nanophotonics.
Published A 'pinch' of mineral salts helps the noncaloric sweeteners go down
(via sciencedaily.com) Original source Perfect noncaloric replacements for sugar and high fructose corn syrup just don't exist yet. For example, some alternatives have a lingering sweet aftertaste and lack a sugar-like mouthfeel, leaving some consumers unsatisfied. Now, researchers propose adding blends of nutritionally important mineral salts to make noncaloric sweeteners seem more like the real thing. Taste-testers indicated that these blends gave zero- and low-calorie drinks a better flavor.
Published Metaverse could put a dent in global warming
