Published Altered carbon points toward sustainable manufacturing
(via sciencedaily.com) Original source Researchers develop a vastly more productive way to convert carbon dioxide into useful materials and compounds.
Published Transition-metal-free zeolite catalyst for direct conversion of methane to methanol
(via sciencedaily.com) Original source Direct oxidation of methane to methanol is dominated by transition- or noble-metal-based catalysts, thus making the reaction quite expensive. To make the process efficient and cost-effective, researchers developed a transition-metal-free aluminosilicate ferrierite zeolite catalyst that can produce methanol by using methane and nitrous oxide as starting materials. The new catalyst ensures excellent methanol production efficiency, one of the highest recorded rates in the literature thus far.
Published Scientists develop 'x-ray vision' technique to see inside crystals
(via sciencedaily.com) Original source A team of researchers has created a new way to visualize crystals by peering inside their structures, akin to having X-ray vision. Their new technique -- which they aptly named 'Crystal Clear' -- combines the use of transparent particles and microscopes with lasers that allow scientists to see each unit that makes up the crystal and to create dynamic three-dimensional models.
Published Fungus breaks down ocean plastic
(via sciencedaily.com) Original source A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers expect that many more plastic degrading fungi are living in deeper parts of the ocean.
Published Children's visual experience may hold key to better computer vision training
(via sciencedaily.com) Original source A novel, human-inspired approach to training artificial intelligence (AI) systems to identify objects and navigate their surroundings could set the stage for the development of more advanced AI systems to explore extreme environments or distant worlds, according to new research.
Published Ancient medicine blends with modern-day research in new tissue regeneration method
(via sciencedaily.com) Original source For centuries, civilizations have used naturally occurring, inorganic materials for their perceived healing properties. Egyptians thought green copper ore helped eye inflammation, the Chinese used cinnabar for heartburn, and Native Americans used clay to reduce soreness and inflammation. Flash forward to today, and researchers are still discovering ways that inorganic materials can be used for healing. A new article explains that cellular pathways for bone and cartilage formation can be activated in stem cells using inorganic ions. Another recent article explores the usage of mineral-based nanomaterials, specifically 2D nanosilicates, to aid musculoskeletal regeneration.
Published Designing environments that are robot-inclusive
(via sciencedaily.com) Original source To overcome issues associated with real-life testing, researchers successfully demonstrated the use of digital twin technology within robot simulation software in assessing a robot's suitability for deployment in simulated built environments.
Published Scientists develop most sensitive way to observe single molecules
(via sciencedaily.com) Original source A technical achievement marks a significant advance in the burgeoning field of observing individual molecules without the aid of fluorescent labels. While these labels are useful in many applications, they alter molecules in ways that can obscure how they naturally interact with one another. The new label-free method makes the molecules so easy to detect, it is almost as if they had labels.
Published New method makes hydrogen from solar power and agricultural waste
(via sciencedaily.com) Original source Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
Published AI saving humans from the emotional toll of monitoring hate speech
(via sciencedaily.com) Original source A team of researchers have developed a new machine-learning method that detects hate speech on social media platforms with 88 per cent accuracy, saving employees from hundreds of hours of emotionally damaging work.
Published The AI paradox: Building creativity to protect against AI
(via sciencedaily.com) Original source Cultivating creativity in schools is vital for a future driven by artificial intelligence (AI). But while teachers embrace creativity as an essential 21st century skill, a lack of valid and reliable creativity tests means schools struggle to assess student achievement. Now, a new machine-learning model is providing teachers with access to high-quality, fit-for-purpose creativity tests, that can score assessments in a fraction of the time and a fraction of the cost.
Published Bio-inspired cameras and AI help drivers detect pedestrians and obstacles faster
(via sciencedaily.com) Original source Artificial intelligence (AI) combined with a novel bio-inspired camera achieves 100 times faster detection of pedestrians and obstacles than current automotive cameras. This important step for computer vision and AI and can greatly improve the safety of automotive systems and self-driving cars.
Published Researchers create materials with unique combo of stiffness, thermal insulation
(via sciencedaily.com) Original source Researchers have demonstrated the ability to engineer materials that are both stiff and capable of insulating against heat. This combination of properties is extremely unusual and holds promise for a range of applications, such as the development of new thermal insulation coatings for electronic devices.
Published Biobased building materials less sustainable than concrete in South Africa, experts find
(via sciencedaily.com) Original source Scientists have discovered that mycelium composites, biobased materials made from fungi and agricultural residues, can have a greater environmental impact than conventional fossil-fuel-based materials due to the high amount of electricity involved in their production.
Published Polymeric films protect anodes from sulfide solid electrolytes
(via sciencedaily.com) Original source Researchers unveil the interaction between polymeric materials and sulfide solid electrolytes.
Published 'The magic of making electricity from metals and air' The vexing carbonate has achieved it!
(via sciencedaily.com) Original source Team develops a high-energy, high-efficiency all-solid-state Na-air battery platform.
Published Tracking animals without markers in the wild
(via sciencedaily.com) Original source Researchers developed a computer vision framework for posture estimation and identity tracking which they can use in indoor environments as well as in the wild. They have thus taken an important step towards markerless tracking of animals in the wild using computer vision and machine learning.
Published Charge your laptop in a minute or your EV in 10? Supercapacitors can help
(via sciencedaily.com) Original source Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes. New research could lead to such advances.
Published AI headphones let wearer listen to a single person in a crowd, by looking at them just once
(via sciencedaily.com) Original source Engineers have developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 'enroll' them. The system then plays just the enrolled speaker's voice in real time, even as the pair move around in noisy environments.
Published Controlling water, transforming greenhouse gases
(via sciencedaily.com) Original source Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
