Published Researchers explore why some people get motion sick playing VR games while others don't
(via sciencedaily.com) Original source The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don't.
Published CO2 recycling: What is the role of the electrolyte?
(via sciencedaily.com) Original source The greenhouse gas carbon dioxide can be converted into useful hydrocarbons by electrolysis. The design of the electrolysis cell is crucial in this process. The so-called zero-gap cell is particularly suitable for industrial processes. But there are still problems: The cathodes clog up quickly.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com) Original source A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published Moving towards 3 degrees of warming -- the phasing out of coal is too slow
(via sciencedaily.com) Original source The use of coal power is not decreasing fast enough. The Paris Agreement's target of a maximum of 2 degrees of warming appear to be missed, and the world is moving towards a temperature increase of 2.5 -- 3 degrees. At the same time it is feasible to avoid higher warming.
Published Sailing cargo ships can benefit from new aerodynamic tech
(via sciencedaily.com) Original source A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as wind-powered ships are more affected by aerodynamic drag than fossil-fueled ones.
Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Team uses natural catalysts to develop low-cost way of producing green hydrogen
(via sciencedaily.com) Researchers have developed a practical way to produce green hydrogen using sustainable catalysts and say their work is a major step towards production simpler, more affordable and more scalable.
Published Probe where the protons go to develop better fuel cells
(via sciencedaily.com) Original source Researchers have uncovered the chemical inner-workings of an electrolyte they developed for a new generation of solid oxide fuel cells. To uncover the location of the proton-introduction reaction, the team studied extensively the hydration reaction of their scandium-substituted barium zirconate perovskite through a combination of synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis. The new data has the potential to accelerate the development of more efficient fuel cells.
Published Public acceptance of fossil fuel subsidy removal could be improved in developing countries
(via sciencedaily.com) People might be more positive to the removal of fuel subsidies if told where the money would be spent instead. This has been shown in a study which investigated attitudes towards removing fossil fuel subsidies in five developing countries.
Published Rsearchers examine combined effects of two combustion technologies on the emission of coal-fired boilers
(via sciencedaily.com) There is currently a large dependence on coal for power generation. As coal-fired plants cause environmental and health hazards, technologies such as swirl flow and air staging have been proposed to mitigate the pollutants in their emissions. However, it is unclear how effective these technologies are in reducing the environmental costs of these plants. Now, researchers have provided insights on this front in a new study, delineating their efficacies with experiments and simulations.
Published Switching to hydrogen fuel could prolong the methane problem
(via sciencedaily.com) Hydrogen is often heralded as the clean fuel of the future, but new research suggests that leaky hydrogen infrastructure could end up increasing atmospheric methane levels, which would cause decades-long climate consequences.
Published Scholars unify color systems using prime numbers
(via sciencedaily.com) Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Plastic upcycling to close the carbon cycle
(via sciencedaily.com) Original source A new method to convert waste plastic to fuel and raw materials promises to help close the carbon cycle at mild temperature and with high yield.
Published Ramping up domestic graphite production could aid the green energy transition
(via sciencedaily.com) Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published 'Game-changing' findings for sustainable hydrogen production
(via sciencedaily.com) Hydrogen fuel could be a more viable alternative to traditional fossil fuels, according to University of Surrey researchers who have found that a type of metal-free catalysts could contribute to the development of cost-effective and sustainable hydrogen production technologies.
Published Video game playing causes no harm to young children's cognitive abilities, study finds
(via sciencedaily.com) Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.
Published How plants are inspiring new ways to extract value from wastewater
(via sciencedaily.com) Scientists are drawing inspiration from plants to develop new techniques to separate and extract valuable minerals, metals and nutrients from resource-rich wastewater.
Published Cheap, sustainable hydrogen through solar power
(via sciencedaily.com) A new kind of solar panel has achieved 9% efficiency in converting water into hydrogen and oxygen--mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.
Published A step towards solar fuels out of thin air
(via sciencedaily.com) Chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous, capable of harvesting water from the air for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare.
