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 Climate change is most prominent threat to pollinators
(via sciencedaily.com) Original source A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
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 Penalties for dropping out of ecosystem services incentive programs should equal lost environmental benefits
(via sciencedaily.com) Original source PES programs are currently structured in ways that could limit their participation or create incentives to drop out before the full environmental benefits are realized.
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 Genetics provide key to fight crown-of-thorns starfish
(via sciencedaily.com) Original source Scientists are one step closer to combating coral-destroying crown-of-thorns starfish, following a study into the pest's genetics.
Published Meet the new insect killing Utah's fir trees
(via sciencedaily.com) Original source The balsam woolly adelgid, a tiny nonnative flightless insect, is spreading across the American West killing subalpine fir in northern Utah's recreation-heavy mountain ranges and canyons. Rsearchers document a close association between the pest's spread and warming temperatures.
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 Mosaic grassland landscapes are the most beneficial
(via sciencedaily.com) Original source Grassland provides many services for humans, animals and nature, such as feed production, carbon storage and recreation. Researchers spent two years investigating permanent grassland, its utilization, soils and plant communities in order to quantify the resulting ecosystem services. Grassland performs best when different types of use such as meadows, pastures and unfertilized extensive grassland exist together in a mosaic landscape.
Published How wildfires change soil chemistry
(via sciencedaily.com) Original source Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
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.
Published Century of statistical ecology reviewed
(via sciencedaily.com) Original source A special review examines highly-cited papers in statistical ecology. The review, which covers a century of research, details how models and concepts have evolved alongside increasing computational power.
Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published Hide and seek between atoms: Find the dopant
(via sciencedaily.com) Original source Collaborative efforts decode the mechanism behind stabilizing cathode doping in electric vehicle batteries.
Published Research explores ways to mitigate the environmental toxicity of ubiquitous silver nanoparticles
(via sciencedaily.com) Original source Researchers have taken a key step toward closing the silver nanoparticles knowledge gap with a study that indicates the particles' shape and surface chemistry play key roles in how they affect aquatic ecosystems.
