Published Organic electronics: Sustainability during the entire lifecycle
(via sciencedaily.com) Original source Organic electronics can make a decisive contribution to decarbonization and, at the same time, help to cut the consumption of rare and valuable raw materials. To do so, it is not only necessary to further develop manufacturing processes, but also to devise technical solutions for recycling as early on as the laboratory phase. Materials scientists are now promoting this circular strategy.
Published Public support hydrogen and biofuels to decarbonize global shipping
(via sciencedaily.com) Original source New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.
Published Scientists propose new strategy for modern sails to help shipping sector meet its carbon reduction goals
(via sciencedaily.com) Original source Researchers have identified a strategy that can offset the random and unpredictable nature of weather conditions that threaten carbon emission reduction efforts in the shipping sector.
Published Wind farm noise exposure doesn't wake people up from their slumber more than road traffic noise
(via sciencedaily.com) Original source Short exposure to wind farm and road traffic noise triggers a small increase in people waking from their slumber that can fragment their sleep patterns, according to new research. But importantly, the new study also shows that wind farm noise isn't more disruptive to sleep than road traffic, which was a little more disruptive at the loudest audio level but not at more common levels. Sleep researchers have studied the impact of exposure to wind farm noise during sleep in three new scientific publications to better understand its impact.
Published City buildings could blow air taxi future off course
(via sciencedaily.com) Original source Air taxis may be coming to our cities in the near future, but a new study warns regulations will need to address dangerous wind gusts around city buildings and other urban infrastructure.
Published Perovskite solar cells set new record for power conversion efficiency
(via sciencedaily.com) Original source Perovskite solar cells have attained now attained the extremely high efficiency rate of 24.35% with an active area of 1 cm2. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources will be crucial to securing the world's energy future.
Published Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
Published Cleaner air with a cold catalytic converter
(via sciencedaily.com) Original source Although passenger vehicle catalytic converters have been mandatory for over 30 years, there is still plenty of room for improvement. For instance, they only work correctly when the engine is sufficiently hot, which is not always the case, especially with hybrid vehicles. Researchers have now developed an improved catalyst that can properly purify exhaust gases even at room temperature.
Published A baking soda solution for clean hydrogen storage
(via sciencedaily.com) Original source Scientists investigate the promising properties of a common, Earth-abundant salt.
Published New material transforms light, creating new possibilities for sensors
(via sciencedaily.com) Original source A new class of materials that can absorb low energy light and transform it into higher energy light might lead to more efficient solar panels, more accurate medical imaging and better night vision goggles.
Published Proposed design could double the efficiency of lightweight solar cells for space-based applications
(via sciencedaily.com) Original source When it comes to supplying energy for space exploration and settlements, commonly available solar cells made of silicon or gallium arsenide are still too heavy to be feasibly transported by rocket. To address this challenge, a wide variety of lightweight alternatives are being explored, including solar cells made of a thin layer of molybdenum selenide, which fall into the broader category of 2D transition metal dichalcogenide (2D TMDC) solar cells. Researchers propose a device design that can take the efficiencies of 2D TMDC devices from 5%, as has already been demonstrated, to 12%.
Published Record 19.31% efficiency with organic solar cells
(via sciencedaily.com) Original source Researchers have achieved a breakthrough power-conversion efficiency (PCE) of 19.31% with organic solar cells (OSCs), also known as polymer solar cells. This remarkable binary OSC efficiency will help enhance applications of these advanced solar energy devices.
Published New catalyst lowers cost for producing environmentally sustainable hydrogen from water
(via sciencedaily.com) Original source A team has developed a new catalyst composed of elements abundant in the Earth. It could make possible the low-cost and energy-efficient production of hydrogen for use in transportation and industrial applications.
Published The next generation of solar energy collectors could be rocks
(via sciencedaily.com) Original source The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.
Published Hydrogen battery: Storing hydrogen in coal may help power clean energy economy
(via sciencedaily.com) Original source The quest to develop hydrogen as a clean energy source that could curb our dependence on fossil fuels may lead to an unexpected place -- coal. Scientists have found that coal may represent a potential way to store hydrogen gas, much like batteries store energy for future use, addressing a major hurdle in developing a clean energy supply chain.
Published New supply chain model to empower seabound hydrogen economy
(via sciencedaily.com) Original source A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Published Demystifying vortex rings in nuclear fusion, supernovae
(via sciencedaily.com) Original source Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source. A mathematical model linking these vortices with more pedestrian types, like smoke rings, could help engineers control their behavior in power generation and more.
Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published Unlocking the power of photosynthesis for clean energy production
(via sciencedaily.com) Original source Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.
