Published Summers warm up faster than winters, fossil shells from Antwerp show
(via sciencedaily.com) Original source In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.
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 Robots' and prosthetic hands' sense of touch could be as fast as humans
(via sciencedaily.com) Original source Research could pave the way for a prosthetic hand and robot to be able to feel touch like a human hand. The technology could also be used to help restore lost functionality to patients after a stroke.
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 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 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 Cats purrfectly demonstrate what it takes to trust robots
(via sciencedaily.com) Original source Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published Today's world: Fastest rate of carbon dioxide rise over the last 50,000 years
(via sciencedaily.com) Original source Today's rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years, researchers have found through a detailed chemical analysis of ancient Antarctic ice.
Published When consumers would prefer a chatbot over a person
(via sciencedaily.com) Original source Actually, sometimes consumers don't want to talk to a real person when they're shopping online, a new study suggests. In fact, what they really want is a chatbot that makes it clear that it is not human at all. In a new study, researchers found that people preferred interacting with chatbots when they felt embarrassed about what they were buying online -- items like antidiarrheal medicine or, for some people, skin care products.
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.
Published Clues from deep magma reservoirs could improve volcanic eruption forecasts
(via sciencedaily.com) Original source New research into molten rock 20km below the Earth's surface could help save lives by improving the prediction of volcanic activity.
Published Scientists unlock key to breeding 'carbon gobbling' plants with a major appetite
(via sciencedaily.com) Original source The discovery of how a critical enzyme 'hidden in nature's blueprint' works sheds new light on how cells control key processes in carbon fixation, a process fundamental for life on Earth. The discovery could help engineer climate resilient crops capable of sucking carbon dioxide from the atmosphere more efficiently, helping to produce more food in the process.
