Published Advances in lithium-metal batteries, paving the way for safer, more powerful devices
(via sciencedaily.com) Original source The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough. Lithium-metal batteries (LMBs) have theoretical capacities an order of magnitude greater than lithium-ion, but a more literal boom has stymied research for decades.
Published Liquid metals shake up century-old chemical engineering processes
(via sciencedaily.com) Original source Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.
Published Charged 'molecular beasts' the basis for new compounds
(via sciencedaily.com) Original source Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules.

(via sciencedaily.com) Original source Researchers have announced a major breakthrough in the field of next-generation solid-state batteries. It is believed that their new findings will enable the creation of batteries based on a novel chloride-based solid electrolyte that exhibits exceptional ionic conductivity.
Published Stronger, stretchier, self-healing plastic
(via sciencedaily.com) Original source An innovative plastic, stronger and stretchier than the current standard type and which can be healed with heat, remembers its shape and partially biodegradable, has been developed. They created it by adding the molecule polyrotaxane to an epoxy resin vitrimer, a type of plastic. Named VPR, the material can hold its form and has strong internal chemical bonds at low temperatures.
Published Making electric vehicles last
(via sciencedaily.com) Original source In the realm of electric vehicles, powered by stored electric energy, the key lies in rechargeable batteries capable of enduring multiple charge cycles. Lithium-ion batteries have been the poster child for this application. However, due to limitations in energy storage capacity and other associated challenges, the focus has shifted to an intriguing alternative known as dual-ion batteries (DIBs).

Published Conduction electrons drive giant, nonlinear elastic response in Sr2RuO4
(via sciencedaily.com) Original source The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4.
Published A potentially cheaper and 'cooler' way for hydrogen transport
(via sciencedaily.com) Original source Researchers have developed a new hydrogen energy carrier material capable storing hydrogen energy efficiently and potentially more cheaply. Each molecule can store one electron from hydrogen at room temperature, store it for up the three months, and can be its own catalyst to extract said electron. Moreover, as the compound is made primarily of nickel, its cost is relatively low.
Published Achieving large and uniform particle sizes
(via sciencedaily.com) Original source Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a method to produce stable polystyrene dispersions with unprecedentedly large, and uniform, particle sizes. Narrow size distributions are essential in many advanced technologies, but were previously difficult to produce photochemically.
Published Diapers can be recycled 200 times faster with light
(via sciencedaily.com) Original source More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.
