From Ancient Fossils to Future Cars
October 21, 2016 11:25 AM - Sarah Nightingale
Researchers at the University of California, Riverside’s Bourns College of Engineering have developed an inexpensive, energy-efficient way to create silicon-based anodes for lithium-ion batteries from the fossilized remains of single-celled algae called diatoms. The research could lead to the development of ultra-high capacity lithium-ion batteries for electric vehicles and portable electronics.
Non-metal catalyst splits hydrogen molecule
October 21, 2016 11:09 AM - Professor Matthias Wagner
Hydrogen (H2) is an extremely simple molecule and yet a valuable raw material which as a result of the development of sophisticated catalysts is becoming more and more important. In industry and commerce, applications range from food and fertilizer manufacture to crude oil cracking to utilization as an energy source in fuel cells. A challenge lies in splitting the strong H-H bond under mild conditions. Chemists at Goethe University have now developed a new catalyst for the activation of hydrogen by introducing boron atoms into a common organic molecule. The process, which was described in theAngewandte Chemie journal, requires only an electron source in addition and should therefore be usable on a broad scale in future.
New perovskite solar cell design could outperform existing commercial technologies, Stanford and Oxford scientists report
October 21, 2016 10:51 AM - Mark Shwartz
A new design for solar cells that uses inexpensive, commonly available materials could rival and even outperform conventional cells made of silicon.
Writing in the Oct. 21 edition of Science, researchers from Stanford and Oxford describe using tin and other abundant elements to create novel forms of perovskite – a photovoltaic crystalline material that’s thinner, more flexible and easier to manufacture than silicon crystals.
New 13-year Study Tracks Impact of Changing Climate on a Key Marine Food Source
October 20, 2016 03:08 PM - Woods Hole Oceanographic Institution
A new multiyear study from scientists at the Woods Hole Oceanographic Institution (WHOI) has shown for the first time how changes in ocean temperature affect a key species of phytoplankton. The study, published in the October 21 issue of the journal Science, tracked levels of Synechococcus—a tiny bacterium common in marine ecosystems—near the coast of Massachusetts over a 13-year period. As ocean temperatures increased during that time, annual blooms of Synechococcus occurred up to four weeks earlier than usual because cells divided faster in warmer conditions, the study found.
Move over, solar: The next big renewable energy source could be at our feet
October 20, 2016 02:56 PM - Will Cushman
Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses alike.
Now, however, flooring could be even more “green,” thanks to an inexpensive, simple method developed by University of Wisconsin–Madison materials engineers that allows them to convert footsteps into usable electricity.
Safe new storage method could be key to future of hydrogen-powered vehicles
October 20, 2016 01:38 PM - University of Cambridge
Hydrogen is often described as the fuel of the future, particularly when applied to hydrogen-powered fuel cell vehicles. One of the main obstacles facing this technology – a potential solution to future sustainable transport – has been the lack of a lightweight, safe on-board hydrogen storage material.
Discovery of Carbon Storage Signaling Mechanism in Algae Offers New Potential for Sustainable Biofuel Production
October 19, 2016 03:44 PM - Donald Danforth Plant Science Center
James Umen, Ph.D., associate member at Donald Danforth Plant Science Center, and colleagues have discovered a way to make algae better oil producers without sacrificing growth. The findings were published September 6, in a paper titled, “Synergism between inositol polyphosphates and TOR kinase signaling in nutrient sensing, growth control and lipid metabolism in Chlamydomonas,” in The Plant Cell. Umen and his team including lead author Inmaculada Couso, Ph.D., and collaborators Bradley Evans Ph.D., director, Proteomics & Mass Spectrometry and Doug Allen, Ph.D., USDA Research Scientist at the Danforth Center identified a mutation in the green alga Chlamydomonas which substantially removes a constraint that is widely observed in micro-algae where the highest yields of oil can only be obtained from starving cultures.
Unraveling the Science Behind Biomass Breakdown
October 18, 2016 04:39 PM - Rachel Harken via Oak Ridge National Laboratory
Lignocellulosic biomass—plant matter such as cornstalks, straw, and woody plants—is a sustainable source for production of bio-based fuels and chemicals. However, the deconstruction of biomass is one of the most complex processes in bioenergy technologies. Although researchers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) had already uncovered information about how woody plants and waste biomass can be converted into biofuel more easily, they have now discovered the chemical details behind that process.
Wave energy researchers dive deep to advance clean energy source
October 13, 2016 07:25 AM - Sandia National Laboratories
One of the biggest untapped clean energy sources on the planet — wave energy — could one day power millions of homes across the U.S. But more than a century after the first tests of the power of ocean waves, it is still one of the hardest energy sources to capture.
While global methane emissions are up, study says fossil fuels not the culprit
October 12, 2016 01:26 PM - Susan Phillips
A new study from NOAA, the National Oceanic Atmospheric Administration, puts a new twist on a tricky question about the impact of increased oil and gas production on greenhouse gas emissions. Scientists have detected increased rates of methane emissions globally since 2007. That uptick corresponds to the rapid boom in U.S. shale gas and shale oil production, and some hypothesized that the two could be connected. But it turns out that the correlation may not necessarily be a cause.
