Bioelectrochemical systems combine the best of both worlds - microbial cells with inorganic materials - to make fuels and other energy-rich chemicals with unrivaled efficiency. Yet technical difficulties have kept them impractical anywhere but in a lab. Now researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a novel nanoscale membrane that could address these issues and pave the way for commercial scale-up.
As part of ongoing acoustic research at Binghamton University, State University at New York Distinguished Professor Ron Miles has created a workable sensor with the least possible resistance to motion.
Cornell University chemical engineering professor Lynden Archer believes there needs to be a battery technology "revolution" - and thinks that his lab has fired one of the first shots.
Supercomputer simulations and theoretical analysis shed new light on when and how fast reconnection occurs.
Elegant techniques of trapping and polarizing atoms open vistas for beta-decay tests of fundamental symmetries, key to understanding the most basic forces and particles constituting our universe.
Atom probe tomography reveals key explanations for stable performance over a cutting-edge diesel-exhaust catalyst's lifetime.
A nickelate thin film senses electric field changes analogous to the electroreception sensing organ in sharks, which detects the bioelectric fields of prey.
Scientists at Pacific Northwest National Laboratory are exploring deep learning to interpret data related to national security, the environment, the cosmos, and breast cancer. In one project a deep neural network is interpreting data about nuclear events as well as - sometimes better than - today's best automated methods or human experts.
Let's talk! Scientists demonstrate coherent coupling between a quantum dot and a donor atom in silicon, vital for moving information inside quantum computers.
Researchers at the Georgia Institute of Technology have found new evidence suggesting that batteries based on sodium and potassium hold promise as a potential alternative to lithium-based batteries.
In an effort to reduce errors in the analyses of diagnostic images by health professionals, a team of researchers from Oak Ridge National Laboratory has improved understanding of the cognitive processes involved in image interpretation, work that has enormous potential to improve health outcomes for the hundreds of thousands of American women affected by breast cancer each year. The ORNL-led team found that analyses of mammograms by radiologists were significantly influenced by context bias, or the radiologist's previous diagnostic experiences.
Scientists have made the first molecular movie of the instant when light hits a sensor that's widely used in nature for probing the environment and harvesting energy from light. The sensor, a form of vitamin A known as retinal, is central to a number of important light-driven processes in people, animals, microbes and algae, including human vision and some forms of photosynthesis, and the movie shows it changing shape in a trillionth of an eye blink.
Scientists have captured the most information yet about proteins within a single human cell, giving scientists one of their clearest looks yet at the molecular happenings inside a human cell. The team detected on average more than 650 proteins in each cell - many times more than conventional techniques capture from single cells.
Using a family of photosynthetic bacteria that commonly live in lakes and seas, researchers at the Technion have developed a technology to generate electricity and hydrogen energy. The researchers believe their technology can serve as a promising source of clean, environment-friendly energy that will not emit pollutants during production or use (hydrogen fuel).
Carbon Nanotube Optics Poised to Provide Pathway to Optical-Based Quantum Cryptography and Quantum Computing
Researchers at Los Alamos and partners in France and Germany are exploring the enhanced potential of carbon nanotubes as single-photon emitters for quantum information processing. Their analysis of progress in the field is published in this week's edition of the journal Nature Materials.
New Tech Uses Isomeric Beams to Study How and Where the Galaxy Makes One of Its Most Common Elements
A new measurement using a beam of aluminum-26 prepared in a metastable state allows researchers to better understand the creation of the elements in our galaxy.
Neutron facilities at Oak Ridge National Laboratory are aiding scientists in research to boost the power and efficiency of thermoelectric materials. These performance increases could enable more cost-effective and practical uses for thermoelectrics, with wider industry adoption, to improve fuel economy in vehicles, make power plants more efficient, and advance body heat-powered technologies for watches and smartphones.
Argonne material scientists have discovered a reaction that helps explain the behavior of a key electrolyte additive used to boost battery performance.
Researchers at the Department of Energy's Joint BioEnergy Institute (JBEI) based at Berkeley Lab have pioneered a new way to synthesize DNA sequences through a creative use of enzymes that promises to be faster, cheaper, and more accurate. DNA synthesis is a fundamental tool in the rapidly growing field of synthetic biology, in which organisms can be engineered to do things like decompose plastic and manufacture biofuels and medicines. This discovery could dramatically accelerate the pace of scientific discovery.
Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert infrared light into light at higher frequencies, are among the smallest continuously emitting lasers of their kind ever reported and can constantly and stably emit light for hours at a time, even when submerged in biological fluids such as blood serum.
Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen. The hydrogen and oxygen can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water, according to a newly published paper in Applied Physics Letters.
A diverse mix of species improves the stability and fuel-oil yield of algal biofuel systems, as well as their resistance to invasion by outsiders, according to the findings of a federally funded outdoor study by University of Michigan researchers.
SLAC and Stanford scientists have discovered how some archaea thrive where other organisms would starve: Their crystalline shells not only protect them from the environment, but they also draw in nutrients through nanosized pores. Those nutrients concentrate in the space between the shell and the microbial cell, so what looks like a famine turns into a feast.
For decades, biologists have believed a key enzyme in plants had one function--produce amino acids, which are vital to plant survival and also essential to human diets. But for Wellington Muchero, Meng Xie and their colleagues, this enzyme does more than advertised. They had run a series of experiments on poplar plants that consistently revealed mutations in a structure of the life-sustaining enzyme that was not previously known to exist.
