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.
Published Like dad and like mum ... all in one plant
(via sciencedaily.com) Original source Scientists have established a system to generate clonal sex cells in tomato plants and used them to design the genomes of offspring. The fertilization of a clonal egg from one parent by a clonal sperm from another parent led to plants containing the complete genetic information of both parents.
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 Some varieties of annual flowers have a place in pollinator-friendly gardens
(via sciencedaily.com) Original source While wildflowers and perennials are a must for supporting pollinators, there's no denying the popularity of many annual flowers for their colorful, visual appeal. A new study suggests choosing the right varieties can give annual flowers a role in nourishing bees and other pollinating insects in home gardens. Researchers observed pollinators visiting the six most popular annual flower species in the U.S., finding significant variation in pollinator attractiveness between cultivars, even within the same flower species.
Published Prostate cancer study: More health benefits from plant-based diet
(via sciencedaily.com) Original source Men with prostate cancer could significantly reduce the chances of the disease worsening by eating more fruits, vegetables, nuts, and olive oil, according to new research.
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 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.
Published New light shed on carboxysomes in key discovery that could boost photosynthesis
(via sciencedaily.com) Original source A research team has discovered how carboxysomes, carbon-fixing structures found in some bacteria and algae, work. The breakthrough could help scientists redesign and repurpose the structures to enable plants to convert sunlight into more energy, paving the way for improved photosynthesis efficiency, potentially increasing the global food supply and mitigating global warming.
Published New 'forever chemical' cleanup strategy discovered
(via sciencedaily.com) Original source A method has been discovered to treat water heavily contaminated with unhealthful forever chemicals, known by chemists as PFAS or poly- and per-fluoroalkyl substances. It involves treating heavily contaminated water with ultraviolet (UV) light, sulfite, and a process called electrochemical oxidation. It breaks up strong fluorine-to-carbon bonds in the PFAS compounds and other concentrated organic compounds in heavily polluted water. The reaction also occurs at room temperature without a need for additional heat or high pressure. This method is expected to be useful in cleanups of PFAS pollution from decades of fire suppressant foam use at military facilities.
Published 2D all-organic perovskites: potential use in 2D electronics
(via sciencedaily.com) Original source Perovskites are among the most researched topics in materials science. Recently, a research team has solved an age-old challenge to synthesize all-organic two-dimensional perovskites, extending the field into the exciting realm of 2D materials. This breakthrough opens up a new field of 2D all-organic perovskites, which holds promise for both fundamental science and potential applications.
