In Science, Los Alamos National Laboratory researchers reveal a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals. The researchers fabricated planar solar cells from pervoskite materials with large crystalline grains that had efficiencies approaching 18%.
Los Alamos National Laboratory has released an updated version of powerful bioinformatics software that is now capable of identifying DNA from viruses and all parts of the Tree of Life—putting diverse problems such as identifying pathogen-caused diseases, selection of therapeutic targets for cancer treatment and optimizing yields of algae farms within relatively easy reach for health care professionals, researchers and others.
Nanocomposite oxide ceramics have potential uses as ferroelectrics, fast ion conductors, and nuclear fuels and for storing nuclear waste, generating a great deal of scientific interest on the structure, properties, and applications of these blended materials. Los Alamos National Laboratory researchers have made the first observations of the relationship between the chemistry and dislocation structures of the nanoscale interfaces.
Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria account for 80% of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.
Using a calculation originally proposed seven years ago to be performed on a petaflop computer, Lawrence Livermore National Laboratory researchers computed conditions that simulate the birth of the universe. When the universe was less than one microsecond old and more than one trillion degrees, it transformed from a plasma of quarks and gluons into bound states of quarks.
A speedy way to mimic the aging of materials inside nuclear reactors has matched all aspects of the damage sustained by a real reactor component for the first time. The method could help the U.S. and other countries stay ahead of potential problems in reactors that run for 40 years or more and also test materials for building advanced reactors.
A multi-phase flow meter, Los Alamos National Laboratory’s Safire provides noninvasive, real-time and accurate estimates of oil production for every well. Jointly developed with Chevron ETC and GE Measurement & Control, Safire achieves measurement rates as high as 100 readings/sec, including computation time.
In an effort to address the apparent shortcomings in modern inspection technology, Los Alamos National Laboratory developed an Acoustic Wavenumber Spectroscopy (AWS) instrument that performs nondestructive inspection more quickly and easily than prior spectroscopy solutions.
Scientists have uncovered key attributes of so-called “brown carbon” from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material’s warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon Univ. and the Univ. of Montana in Nature Geosciences.
Laser technology originally developed at Los Alamos National Laboratory for the Mars Science Laboratory has been selected for NASA’s new Mars mission in 2020. The Curiosity rover is equipped with ChemCam, which allows researchers to sample rocks and other targets from a distance using a laser. The new “SuperCam” will offer this capability along with another spectrum for Raman and time-resolved fluorescence spectroscopy.
Los Alamos National Laboratory researchers have demonstrated an almost four-fold boost of the carrier multiplication yield with nanoengineered quantum dots. Carrier multiplication is when a single photon can excite multiple electrons. Quantum dots are novel nanostructures that can become the basis of the next generation of solar cells, capable of squeezing additional electricity out of the extra energy of blue and ultraviolet photons.
A new facility for using protons to take microscopic images has been commissioned at the ring accelerator of the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany. Protons, like neutrons, are the building blocks of atomic nuclei. Similar to x-rays, they can be used to radiograph objects, generating images of them. Protons are able to penetrate hot dense matter that can't be examined with light or x-rays.
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum dot work by Los Alamos National Laboratory researchers in collaboration with scientists from Univ. of Milano-Bicocca, Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.
Interest in oxide-based semiconductor electronics has exploded in recent years, fueled largely by the ability to grow atomically precise layers of various oxide materials. One of the most important materials in this burgeoning field is strontium titanate, a nominally nonmagnetic wide-bandgap semiconductor, and researchers have found a way to magnetize this material using light, an effect that persists for hours at a time.
Call it “homo minutus”. A team at Los Alamos National Laboratory is developing four human organ constructs (liver, heart, lung and kidney) that will work together to serve as a drug and toxicity analysis system that can mimic the actual response of human organs. Called ATHENA, for Advanced Tissue-engineered Human Ectypal Network Analyzer, the system will fit neatly on a desk.
Scientists at Los Alamos National Laboratory are working toward even stronger and more elastic glass types which would fail in a ductile fashion instead of shattering. Researchers there are looking at the initiation of shear-banding events in order to better understand how to control the mechanical properties of these materials.
A team NIST scientists, with collaborators elsewhere, has achieved a five-fold reduction in the dominant uncertainty in an experiment that measured the mean lifetime of the free neutron, resulting in a substantial improvement of previous results. However, the accomplishment reveals a puzzling discrepancy when compared to different method, and researchers are planning to re-run the experiment in upgraded form.
A ground-penetrating bomb, minus its nuclear components, rammed through a target at the remote Coyote Canyon test range last month in Sandia National Laboratories’ first such rocket-driven impact test in seven years. Engineers said the Sandia components on the weapon performed as expected.
Solar cells made with low-cost, nontoxic quantum dots can achieve unprecedented longevity and efficiency, according to a study by Los Alamos National Laboratory and Sharp Corp. The reported solar cells are based on nontoxic quantum dots. These dots are based on copper indium selenide sulfide and are rigorously optimized to reduce charge-carrier losses from surface defects and to provide the most complete coverage of the solar spectrum.
The ChemCam laser instrument aboard NASA’s Curiosity rover fired its 100,000th shot recently, chronicling its adventures on Mars with a coffee-table-book’s worth of spectral data that might rival snapshots gathered during a long and satisfying family vacation here on Earth. ChemCam zaps rocks with a high-powered laser to determine their composition and carries a camera that can survey the Martian landscape.
Los Alamos National Laboratory scientists have advanced a magnetic resonance imaging (MRI) technology that may provide a breakthrough for screening liquids at airport security. They’ve added low-power x-ray data to the mix, and as a result have unlocked a new detection technology.
Researchers at Los Alamos National Laboratory are investigating the complex relationships between the spread of the HIV virus in a population (epidemiology) and the actual, rapid evolution of the virus (phylogenetics) within each patient’s body. The team models the uninfected population using traditional differential equations on the computer; this is done for computational speed, because an agent-based component is much more demanding.
A new collaborative science program is pioneering the development of ultra-sensitive methane-sensing technology. Methane, the principal component of natural gas, is one of many gases whose presence in the atmosphere contributes to global climate change. It is a goal of industry and scientists alike to better constrain the source flux of fugitive methane emissions from man-made activities.
