(via sciencedaily.com) Original source A research team reports a pioneering plasma-catalytic process for the hydrogenation of CO2 to methanol at room temperature and atmospheric pressure. This breakthrough addresses the limitations of traditional thermal catalysis, which often requires high temperatures and pressures, resulting in low CO2 conversion and methanol yield.
Published 3D laser printing with bioinks from microalgae
(via sciencedaily.com) Original source Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.
Published New technology uses light to engrave erasable 3D images
(via sciencedaily.com) Original source Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
Published Finding pearls in the mud: Eco-friendly tungsten recovery from semiconductor waste
(via sciencedaily.com) Original source Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.
Published Chemists develop new sustainable reaction for creating unique molecular building blocks
(via sciencedaily.com) Original source Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers have myriad applications -- from drug delivery to construction materials -- their structures and functions are restricted by the chemically similar monomer building blocks they're composed of. Now, chemists have developed a new reaction to create unique monomers in a controlled way. This reaction, which uses nickel as a catalyst, ultimately enables scientists to create polymers with unique and modifiable properties for drug delivery, energy storage, microelectronics and more.
Published Breakthrough in molecular control: New bioinspired double helix with switchable chirality
(via sciencedaily.com) Original source The control of artificial double-helical structures, which are essential for the development of high-order molecular systems, remains difficult. In a new study, researchers have developed novel double-helical monometallofoldamers that exhibit controllable helicity inversion and chiral information transfer, in response to external stimuli. These monometallofoldamers can lead to novel artificial supramolecular systems for molecular information transmission, amplification, replication, and other exciting applications in various fields of technology.
Published International Space Station crew carries out archeological survey in space
(via sciencedaily.com) Original source An archaeological strategy adapted for space used daily photos to reveal how astronauts actually use areas aboard the International Space Station -- and how this differs from intended uses.
Published Forever chemical pollution can now be tracked
(via sciencedaily.com) Original source Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published Findings from first archaeology project in space
(via sciencedaily.com) Original source The first-ever archeological survey in space has provided new insights into how astronauts use and adapt their living space on the International Space Station, which could influence the design of new space stations after the ISS is decommissioned.
Published Scientists lay out revolutionary method to warm Mars
(via sciencedaily.com) Original source Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment.
Published Advanced chelators offer efficient and eco-friendly rare earth element recovery
(via sciencedaily.com) Original source The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.
Published Concept for efficiency-enhanced noble-metal catalysts
(via sciencedaily.com) Original source The production of more than 90 percent of all chemical products we use in our everyday lives relies on catalysts. Catalysts speed up chemical reactions, can reduce the energy required for these processes, and in some cases, reactions would not be possible at all without catalysts. Researchers developed a concept that increases the stability of noble-metal catalysts and requires less noble metal for their production.
