Published Breaking bonds to form bonds: Rethinking the Chemistry of Cations
(via sciencedaily.com) Original source A team of chemists has achieved a significant breakthrough in the field of chemical synthesis, developing a novel method for manipulating carbon-hydrogen bonds. This groundbreaking discovery provides new insights into the molecular interactions of positively charged carbon atoms. By selectively targeting a specific C--H bond, they open doors to synthetic pathways that were previously closed -- with potential applications in medicine.
Published Wind farms can offset their emissions within two years
(via sciencedaily.com) Original source After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.
Published Bioengineered enzyme creates natural vanillin from plants in one step
(via sciencedaily.com) Original source Vanilla, the most widely used flavoring compound in confectionaries and cosmetics, gets its sweet flavor and aroma from the chemical compound -- 'vanillin'. However, the large-scale production of natural vanillin is impeded by the lack of microbial processes and enzymes which can commercially generate vanillin. Now, researchers have genetically engineered a novel enzyme which can convert ferulic acid from plant waste into vanillin in a one-step sustainable process.
Published Carbon-capture batteries developed to store renewable energy, help climate
(via sciencedaily.com) Original source Researchers are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide. Researchers recently created and tested two different formulations for batteries that store renewable energy; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products.
Published Making batteries takes a lot of lithium: Some could come from gas well wastewater
(via sciencedaily.com) Original source A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Published A novel multifunctional catalyst turns methane into valuable hydrocarbons
(via sciencedaily.com) Original source The optimal design of a novel zeolite catalyst enables tandem reaction that turns greenhouse gases into value-added chemicals, report scientists. By tuning the separation between different active sites on the catalyst, they achieved the stepwise conversion of methane into methanol and then to hydrocarbons at mild conditions. These findings will help reduce energy costs and greenhouse gas emissions across various industrial fields.
Published Much more than a world first image of radioactive cesium atoms
(via sciencedaily.com) Original source Thirteen years after the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant (FDNPP), a breakthrough in analysis has permitted a world first: direct imaging of radioactive cesium (Cs) atoms in environmental samples.
Published Green concrete recycling twice the coal ash is built to last
(via sciencedaily.com) Original source New modelling reveals that low-carbon concrete can recycle double the amount of coal ash compared to current standards, halve the amount of cement required and perform exceptionally well over time.
Published Polyglycerol coating: A breakthrough in safer nanoparticle environmental remediation
(via sciencedaily.com) Original source Engineered nanoparticles (NPs), commonly utilized in environmental remediation, can pose significant toxicity risks upon ingestion by organisms. Researchers have now devised a solution to this challenge by creating a hydrophilic coating, utilizing polyglycerol (PG) functionalization, for NPs. This coating effectively prevents NP aggregation inside organisms' bodies and facilitates easier passage, thereby reducing accumulation. Applicable to various NPs, the novel surface functionalization approach holds promise for addressing concerns about NP toxicity in environmental remediation.
Published Next-generation sustainable electronics are doped with air
(via sciencedaily.com) Original source Semiconductors are the foundation of all modern electronics. Now, researchers have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study is a significant step towards future cheap and sustainable organic semiconductors.
Published Promising new development in solar cell technology
(via sciencedaily.com) Original source Researchers who contributed to the development of record-breaking solar cells a few years ago, expanded their invention. The self-assembled monolayers can now be applied not only in inverted but also in regular structure perovskite solar cells.
Published Scientists develop an affordable sensor for lead contamination
(via sciencedaily.com) Original source A new system could enable simple, low-cost detectors for monitoring water for lead contamination, and potentially other heavy metals as well.
Published Metalens expands Its reach from light to sound
(via sciencedaily.com) Original source Engineers achieve a wide field-of-hearing acoustic metalens free from aberrations.
Published Transforming waste carbon dioxide into high-value chemicals with a cost reduction of about 30%
(via sciencedaily.com) Original source A team of scientists has developed a novel technique to convert carbon dioxide (CO2) from treated flue gas directly into high-value chemicals and fuels. This innovation sidesteps the conventional approach of using high-purity CO2 for electrochemical reduction processes, achieving significant cost savings of about 30%.
Published Eco-friendly and affordable battery for low-income countries
(via sciencedaily.com) Original source A battery made from zinc and lignin that can be used over 8000 times. This has been developed with a vision to provide a cheap and sustainable battery solution for countries where access to electricity is limited.
Published Avocado pruning residues used to produce more sustainable food packaging
(via sciencedaily.com) Original source A prototype of a more durable material increases the biodegradability of food packaging, partially replacing its bioplastic with cellulose fibers extracted from the branches and leaves of the avocado tree.
Published How to make ubiquitous plastics biodegradable
(via sciencedaily.com) Original source Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process. The plastic can't be broken down by biotechnological means, either. Researchers are looking for ways to rectify this: An international team decoded a bacterial enzyme that plays a key role in styrene degradation. This paves the way for biotechnological application.
