Published Sea level rise shifts habitat for endangered Florida Keys species
(via sciencedaily.com) Original source A newly published study describes the response to sea level rise by the silver rice rat, an endangered species only found in the Florida Keys.
Published North Atlantic Oscillation contributes to 'cold blob' in Atlantic Ocean
(via sciencedaily.com) Original source A patch of ocean in the North Atlantic is stubbornly cooling while much of the planet warms. This anomaly -- dubbed the 'cold blob' -- has been linked to changes in ocean circulation, but a new study found changes in large-scale atmospheric patterns may play an equally important role, according to an international research team.
Published California's winter waves may be increasing under climate change
(via sciencedaily.com) Original source A new study uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heated up the planet.
Published Cracking in lithium-ion batteries speeds up electric vehicle charging
(via sciencedaily.com) Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.
Published Energy-storing supercapacitor from cement, water, black carbon
(via sciencedaily.com) Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
Published Scientists create novel approach to control energy waves in 4D
(via sciencedaily.com) Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published Secondary forests more sensitive to drought than primary forests
(via sciencedaily.com) Original source The dry summer of 2018 hit Swedish forests hard -- and hardest affected were the managed secondary forests.
Published New research method determines health impacts of heat and air quality
(via sciencedaily.com) Original source The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published A butterfly's first flight inspires a new way to produce force and electricity
(via sciencedaily.com) Original source Researchers have uncovered the promising capability of chitin as a sustainable smart biomaterial. Through water exchange with the environment, humidity-responsive chitinous films can generate mechanical and electrical energy for potential use in engineering and biomedical applications.
Published 'Quantum avalanche' explains how nonconductors turn into conductors
(via sciencedaily.com) Original source The study takes a new approach to answer a long-standing mystery about insulator-to-metal transitions.
Published Risk of fatal heart attack may double in heat wave and high fine particulate pollution days
(via sciencedaily.com) Original source An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults.
Published Renewable solar energy can help purify water, the environment
(via sciencedaily.com) Chemists have demonstrated that water remediation can be powered in part -- and perhaps even exclusively -- by renewable energy sources.
Published Long-term changes in waves and storm surges have not impacted global coastlines
(via sciencedaily.com) Original source Changes in ocean wave and storm conditions have not caused long-term impacts on sandy coastlines in the past 30 years, a new study has found.
Published Climate science is catching up to climate change with predictions that could improve proactive response
(via sciencedaily.com) Original source In Africa, climate change impacts are experienced as extreme events like drought and floods. It has now been possible to predict and monitor these climatic events, providing early warning of their impacts on agriculture to support humanitarian and resilience programming in the most food insecure countries of the world.
Published Device makes hydrogen from sunlight with record efficiency
(via sciencedaily.com) Engineers have created a device that turns sunlight into hydrogen with record-breaking efficiency by integrating next-generation halide perovskite semiconductors with electrocatalysts in a single, durable, cost-effective and scalable device.
Published Aluminum materials show promising performance for safer, cheaper, more powerful batteries
(via sciencedaily.com) Researchers are using aluminum foil to create batteries with higher energy density and greater stability. The team's new battery system could enable electric vehicles to run longer on a single charge and would be cheaper to manufacture -- all while having a positive impact on the environment.
Published Researchers put a new twist on graphite
(via sciencedaily.com) Original source Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.
Published Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries
(via sciencedaily.com) Early experiments have revealed significant benefits to a dry battery manufacturing process. This eliminates the use of toxic solvents while showing promise for delivering a battery that is durable, less weighed down by inactive elements and able to maintain high energy storage capacity after use. Such improvements could boost wider EV adoption, helping to reduce carbon emissions and achieve U.S. climate goals.
Published Researchers achieve historic milestone in energy capacity of supercapacitors
(via sciencedaily.com) Original source In a new landmark chemistry study, researchers describe how they have achieved the highest level of energy storage -- also known as capacitance -- in a supercapacitor ever recorded.
Published Bifacial perovskite solar cells point to higher efficiency
(via sciencedaily.com) A bifacial perovskite solar cell, which allows sunlight to reach both sides of the device, holds the potential to produce higher energy yields at lower overall costs.
