A powerful new material developed by Northwestern University chemist William Dichtel and his research team could one day speed up the charging process of electric cars and help increase their driving range.
An electric car currently relies on a complex interplay of both batteries and supercapacitors to provide the energy it needs to go places, but that could change.
"Our material combines the best of both worlds -- the ability to store large amounts of electrical energy or charge, like a battery, and the ability to charge and discharge rapidly, like a supercapacitor," said Dichtel, a pioneer in the young research field of covalent organic frameworks (COFs).
A group of southern elephant seals is helping scientists monitorhow climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent.
In the hills near Los Angeles, the Blue Cut Fire just ripped through 36,000 acres, taking dozens of homes along with it, spurring a major evacuation, and even requiring temporary highway closures. But the merciless flames of the Blue Cut Fire almost pale in comparison with the flood of wildfires across the Golden State, and the West at large, in an era when the wildfire season is growing longer and more aggressive every year. Climate change is the reason why, and researchers are discovering that the cost of wildfires may be bigger than we imagined: They’re tracking deadly “smoke waves” that sweep the landscape, causing serious respiratory health problems.
Some water ferns can absorb large volumes of oil within a short time, because their leaves are strongly water-repellent and, at the same time, highly oil-absorbing. Researchers of KIT, together with colleagues of Bonn University, have found that the oil-binding capacity of the water plant results from the hairy microstructure of its leaves. It is now used as a model to further develop the new Nanofur material for the environmentally friendly cleanup of oil spills. (DOI: 10.1088/1748-3190/11/5/056003)
Damaged pipelines, oil tanker disasters, and accidents on oil drilling and production platforms may result in pollutions of water with crude or mineral oil. Conventional methods to clean up the oil spill are associated with specific drawbacks.
This year’s melt season in the Arctic Ocean and surrounding seas started with a bang, with a record low maximum extent in March and relatively rapid ice loss through May. The melt slowed down in June, however, making it highly unlikely that this year’s summertime sea ice minimum extent will set a new record.
A University of Alaska Fairbanks-led research project has provided the first modern evidence of a landscape-level permafrost carbon feedback, in which thawing permafrost releases ancient carbon as climate-warming greenhouse gases.
The study was published today in the journal Nature Geoscience.
The project, led by UAF researcher Katey Walter Anthony, studied lakes in Alaska, Canada, Sweden and Siberia where permafrost thaw surrounding lakes led to lake shoreline expansion during the past 60 years. Using historical aerial photo analysis, soil and methane sampling, and radiocarbon dating, the project quantified for the first time the strength of the present-day permafrost carbon feedback to climate warming. Although a large permafrost carbon emission is expected to occur imminently, the results of this study show nearly no sign that it has begun.
According to Redfin, several American cities – some the usual progressive suspects, but others quite surprising – are making moves to build more homes in walkable neighborhoods. Other, however, are stuck in the past, building more of the distant suburbs.
Why do we need more walkable cities? Quite simply because walkable cities are, by definition, sustainable cities. Transportation remains a major source of greenhouse gas pollution, and, unlike electricity or agriculture, the United States remains firmly stuck on a fossil-fuel dependent transport infrastructure. When we live in spread out suburbs, far from work, shopping, schools, and cultural centers, we have to drive. Often, we drive inefficient, single-occupancy vehicles, burning more fossil fuels, and creating more traffic.
America’s massive, growing landfills are the result of many decades of bad policies and decisions. And it will take a concerted, society-wide effort to solve this problem. Let’s dive deeper into just how big our landfill waste problem is and how we can begin to shift toward a circular economy.
A new study led by Scripps Institution of Oceanography at the University of California San Diego scientist Jane Willenbring challenges the long-held belief that asbestos fibers cannot move through soil. The findings have important implications for current remediation strategies aimed at capping asbestos-laden soils to prevent human exposure of the cancer-causing material.
Willenbring, along with University of Pennsylvania postdoctoral researcher Sanjay Mohanty, and colleagues tested the idea that once capped by soil, asbestos waste piles are locked in place. Instead they found that dissolved organic matter contained within the soil sticks to the asbestos particles, creating a change of the electric charge on the outside of the particle that allows it to easily move through the soil.
A Bosnian pine (Pinus heldreichii) growing in the highlands of northern Greece has been dendrocronologically dated to be more than 1075 years old. This makes it currently the oldest known living tree in Europe. The millenium old pine was discovered by scientists from Stockholm University (Sweden), the University of Mainz (Germany) and the University of Arizona (USA).
