As you drive down the highway, you may notice an increasing number of hybrid and electric vehicles. Alternative energy automobiles are on the rise contributing to the global effort to reduce carbon emissions. As we move together down this road, researchers are looking to determine new solutions to this ongoing problem.
In two new studies on life in the seafloor of the Guaymas Basin, in the Gulf of California, Marine Biological Laboratory scientist Emil Ruff and collaborators show that distinct regions within the Basin harbor specially adapted microorganisms; discover new microbial inhabitants of this deep-sea community; and suggest how the community may be dramatically influencing carbon cycling in the hot seafloor sediments.
Millions of litres of primary municipal wastewater can be treated sustainably using fast-growing willow trees while also producing renewable bioenergy and 'green' chemicals, researchers find.
A novel way of synthesizing an essential powder is key to raising the efficiency of perovskite solar cells, say researchers at the Okinawa Institute of Science and Technology Graduate University.
Rice University engineers have created microscopic seeds for growing remarkably uniform 2D perovskite crystals that are both stable and highly efficient at harvesting electricity from sunlight.
A Penn State-led team of researchers reports that it has taken a step toward overcoming the challenge of inexpensive hydrogen production by using supercomputers to find materials that could help accelerate hydrogen separation when water is exposed to light, a process called photocatalysis.
Scientists have used a compound made from a starch derivative and baking soda to help convert mechanical to electrical energy. The approach, developed by scientists at Daegu Gyeongbuk Institute of Technology (DGIST), with colleagues in Korea and India, is cost-effective and biocompatible, and can help charge low-energy electronics like calculators and watches. The details were published in the journal Advanced Functional Materials.
For the most accurate accounting of a product's environmental impact, scientists look at the product's entire life cycle, from cradle to grave. It's a grand calculation known as a life cycle assessment (LCA), and greenhouse gas emissions are a key component. For corn ethanol, most greenhouse gas emissions can be mapped to the fuel's production, transportation, and combustion, but a large portion of the greenhouse gas calculation can be traced right back to the farm.
Scientists at Friedrich Schiller University in Jena, together with colleagues from Boston University (BU) and Wayne State University (WSU), have now succeeded in preventing dendrite formation and thus at least doubling the lifetime of a lithium metal battery. The researchers report on their method in the renowned journal "Advanced Energy Materials".
Using a numerical model that simulates ocean currents, researchers are shedding light on the important "motion of the ocean" in the Straits of Florida. They have conducted a first-of-its-kind study identifying the mechanisms behind the formation of sub-mesoscale eddies, which have important environmental implications and play a significant role in the health of the Florida Keys coral reef ecosystem.
