A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices.
Magnesium -- the lightest of all structural metals -- has a lot going for it in the quest to make ever lighter cars and trucks that go farther on a tank of fuel or battery charge.Magnesium is 75 percent lighter than steel, 33 percent lighter than aluminum and is the fourth most common element on earth behind iron, silicon and oxygen.
Research Center Established to Explore the Least Understood and Strongest Force Behind Visible Matter
Science can explain only a small portion of the matter that makes up the universe, from the earth we walk on to the stars we see at night. Stony Brook University and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) have established the Center for Frontiers of Nuclear Science to help scientists better understand the building blocks of visible matter. The new Center will push the frontiers of knowledge about quarks, gluons and their interactions that form protons, neutrons, and ultimately 99.9 percent of the mass of atoms - the bulk of the visible universe.
Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy than natural photosynthesis can, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.
In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists were able to observe "diamond rain" for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior.
The U.S. Department of Energy's Argonne National Laboratory and United Scientific Supplies, Inc. are introducing high school students to nanoscience with a new hands-on product.
Article describes use of second neutral beam injector to suppress instabilities on the NSTX-U
A research team has created for the first time a movie with nanoscale resolution of the three-dimensional changes a virus undergoes as it prepares to infect a healthy cell. The scientists analyzed thousands of individual snapshots from intense X-ray flashes, capturing the process in an experiment at the Department of Energy's SLAC National Accelerator Laboratory.
Solar panels have tremendous potential to provide affordable renewable energy, but many people see traditional black and blue panels as an eyesore. Architects, homeowners and city planners may be more open to the technology if they could install colorful, efficient solar panels, and a new study, published this week in Applied Physics Letters, brings us one step closer. Researchers have developed a method for imprinting existing solar panels with silicon nanopatterns that scatter green light back toward an observer.
Scientists at Berkeley Lab and Purdue University developed new theories and 3-D simulations to explain what's at work in the mysterious jets of energy and matter beaming from the center of galaxies at nearly the speed of light.
Study finds opinion and emotion in tweets change when you get sick, a method public health workers could use to track health trends.
California's plan to cut energy consumption by 80 percent by 2050 cannot be achieved with current proposed policy changes because most solutions focus on changing technologies rather than changing behavior, a new UC Davis study suggests.
Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have engineered a new material to be used in redox flow batteries, which are particularly useful for storing electricity for the grid. The material consists of carefully structured molecules designed to be particularly electrochemically stable in order to prevent the battery from losing energy to unwanted reactions.
PPPL research performed with collaborators from Princeton University and the Institute for Advanced Computational Science at the State University of New York at Stony Brook has shown how plasma causes exceptionally strong, microscopic structures known as carbon nanotubes to grow.
The ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help birds and bats near offshore wind turbines.
An innovation providing key clues to how humans might manage forests and cities to cool the planet is taking flight. Cornell researchers are using drone technology to more accurately measure surface reflectivity on the landscape, a technological advance that could offer a new way to manage climate change.
The city of the future could start with a village - Missouri University of Science and Technology's Solar Village, to be exact. S&T researchers will study the Solar Village and its residents as their living laboratory over the next three years thanks to an $800,000 grant from the National Institute of Food and Agriculture, funded as part of the National Science Foundation's Cyber-Physical System initiative. The research team is led by Dr. Simone Silvestri, principal investigator and assistant professor of computer science, and Dr. Denise Baker, co-principal investigator and assistant professor of psychological science
A computer code used by physicists around the world to analyze and predict tokamak experiments can now approximate the behavior of highly energetic atomic nuclei, or ions, in fusion plasmas more accurately than ever.
In Nature Biotechnology, an international team led by DOE Joint Genome Institute researchers has developed standards for the minimum metadata to be supplied with single amplified genomes (SAGs) and metagenome-assembled genomes (MAGs) submitted to public databases.
America's use of distributed wind - which is wind power generated near where it will be used - continues to grow, according to the 2016 Distributed Wind Market Report.
Annual Wind Power Report Confirms Technology Advancements, Improved Project Performance, and Low Wind Energy Prices
Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the U.S. Department of Energy and prepared by Berkeley Lab. Prices offered by newly built wind projects in the United States are averaging around 2 cents/kWh, driven lower by technology advancements and cost reductions.
Researchers at Binghamton University, State University of New York have developed the next step in microbial fuel cells (MFCs): a battery activated by spit that can be used in extreme conditions where normal batteries don't function.
Environmental scientists led by the Virginia Tech College of Science have discovered that the burning of coal produces incredibly small airborne particles of a highly unusual form of titanium oxide with the potential to be toxic to humans.
After more than a year of operation at Oak Ridge National Laboratory, the COHERENT experiment, using the world's smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.
New work at Los Alamos and Oak Ridge national laboratories is resolving difficult fuel-cell performance questions, both in determining efficient new materials and understanding how they work at an atomic level.
