Published Discovery brings all-solid-state sodium batteries closer to practical use
(via sciencedaily.com) Original source Researchers have developed a mass synthesis process for sodium-containing sulfides. Mass synthesis of electrolytes with high conductivity and formability is key to the practical use of all-solid-state sodium batteries, thought to be safer than lithium-ion batteries and less expensive, as sodium is far more plentiful than lithium.
Published New strategy for assessing the applicability of reactions
(via sciencedaily.com) Original source Chemists show that a machine-based method prevents widespread 'bias' in chemical publications.
Published Revolutionary molecular device unleashes potential for targeted drug delivery and self-healing materials
(via sciencedaily.com) Original source In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
Published New device gathers, stores electricity in remote settings
(via sciencedaily.com) Original source Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
Published Subterranean storage of hydrogen
(via sciencedaily.com) Original source Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Published Do some mysterious bones belong to gigantic ichthyosaurs?
(via sciencedaily.com) Original source Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.
Published Scientists unveil cutting-edge ruthenium catalyst for new reaction discovery and optimization
(via sciencedaily.com) Original source Researchers have achieved a groundbreaking advancement in catalyst technology.
Published Using pulp and paper waste to scrub carbon from emissions
(via sciencedaily.com) Original source Researchers have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production. The technique they've pioneered not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.
Published How scientists are accelerating chemistry discoveries with automation
(via sciencedaily.com) Original source Scientists have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new automated approach could analyze chemical reactions in real time and identify new chemical-reaction products much faster than current laboratory methods.
Published A simple, inexpensive way to make carbon atoms bind together
(via sciencedaily.com) Original source The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs.
Published Dinosaur study challenges Bergmann's rule
(via sciencedaily.com) Original source A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.
Published Chemical reactions can scramble quantum information as well as black holes
(via sciencedaily.com) Original source A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published Rapid, simultaneous detection of multiple bacteria achieved with handheld sensor
(via sciencedaily.com) Original source A team has developed a method for simultaneous detection of multiple disease-causing bacterial species within one hour using a handheld device.
Published 'Tug of war' tactic enhances chemical separations for critical materials
(via sciencedaily.com) Original source Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.
Published Developing a vaccine for the 'zombie drug' xylazine
(via sciencedaily.com) Original source Chemical biologists design an early 'proof-of-concept' vaccine that could lead to the first effective treatment of xylazine overdose in people.
Published Early dinosaurs grew up fast, but they weren't the only ones
(via sciencedaily.com) Original source The earliest dinosaurs had rapid growth rates, but so did many of the other animals living alongside them, according to a new study.
Published Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries
(via sciencedaily.com) Original source Researchers have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries that enables efficient charging and discharging even at low temperatures.
Published Plastic-free vegan leather that dyes itself grown from bacteria
(via sciencedaily.com) Original source Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
Published Water-based paints: Less stinky, but some still contain potentially hazardous chemicals
(via sciencedaily.com) Original source Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.
Published When did the chicken cross the road? New evidence from Central Asia
(via sciencedaily.com) Original source An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.
