Energy storage startup SPARKZ Inc. has exclusively licensed five battery technologies from the Department of Energy's Oak Ridge National Laboratory designed to eliminate cobalt metal in lithium-ion batteries. The advancement is aimed at accelerating the production of electric vehicles and energy storage solutions for the power grid.
The first hours of a lithium-ion battery's life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come. Now scientists have witnessed the formation of the solid-electrolyte interphase at a molecular level.
Chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have made a new finding about battery performance that points to a different strategy for optimizing cathode materials. Their research, published in Chemistry of Materials and featured in ACS Editors' Choice, focuses on controlling the amount of structural defects in the cathode material.
Scientists solved a critical part of the mystery of photosynthesis, focusing on the initial, ultrafast events through which photosynthetic proteins capture light and use it to initiate a series of electron transfer reactions.
In a collaborative project with MIT and other universities, scientists at Argonne National Laboratory have experimentally detected the fleeting transition state that occurs at the origin of a chemical reaction.
An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades--a feature that could possibly facilitate superconductivity at or near room temperature and pressure. The scientists conducted neutron scattering experiments at the Department of Energy's Oak Ridge National Laboratory on samples of zirconium vanadium hydride.
Purely electronic interactions could be behind copper-oxygen compounds conducting electricity without resistance at relatively high temperatures.
Science Snapshot From Berkeley Lab - a biocompatible material that turns up the heat on antibacterial-resistant diseases
Scientists at Berkeley Lab's Molecular Foundry have designed a biocompatible polymer that has the potential to advance photothermal therapy, a technique that deploys near-infrared light to combat antibacterial-resistant infections and cancer.
The production of formate from CO2 is considered an attractive strategy for the long-term storage of solar renewable energy in chemical form.
Materials that can host this exotic liquid-like magnetic state could be harnessed for next-generation energy and computing applications.
The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows. The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.
In Nature, a team led by U.S. Department of Energy (DOE) Joint Genome Institute (JGI) researchers uncovered a broad diversity of large and giant viruses that belong to the nucleocytoplasmic large DNA viruses (NCLDV) supergroup, expanding virus diversity in this group 10-fold from just 205 genomes.
Scientists for the first time have developed a single molecule that can absorb sunlight efficiently and also act as a catalyst to transform solar energy into hydrogen, a clean alternative to fuel for things like gas-powered vehicles. This new molecule collects energy from the entire visible spectrum, and can harness more than 50% more solar energy than current solar cells can. The finding could help humans transition away from fossil fuels and toward energy sources that do not contribute to climate change.
State-of-the-art simulation confirms a key source of heat and energy loss in spherical fusion facilities.
A new study that incorporates datasets gathered from more than 100 sites by institutions including the U.S. Department of Energy's (DOE) Argonne National Laboratory, suggests that decomposition of organic matter in permafrost soil is substantially larger than previously thought, demonstrating the significant impact that emissions from the permafrost soil could have on the greenhouse effect and global warming.
Scientists from Cornell University and Brookhaven National Laboratory (BNL) have successfully demonstrated the world's first capture and reuse of energy in a multi-turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline.
It represents an entirely new type of ground state for transition metal oxides, and opens new directions for experiments and theoretical studies of how superconductivity arises and how it can be optimized in this system and possibly in other compounds.
Experimental physicists have combined several measurements of quantum materials into one in their ongoing quest to learn more about manipulating and controlling the behavior of them for possible applications. They even coined a term for it-- Magneto-elastoresistance, or MER.
In a new study, scientists have developed a new type of semiconductor neutron detector that boosts detection rates by reducing the number of steps involved in neutron capture and transduction.
Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of matter and dimmer where matter is sparser - a correlation that could help them narrow down the properties of exotic astrophysical objects and invisible dark matter.
A new DNA-programmable nanofabrication platform organizes inorganic or biological nanocomponents in the same prescribed ways.
Scientists often make progress by coming up with new ways to look at old problems. That has happened at PPPL, where physicists have used a simple insight to capture the complex effects of many high-frequency waves in a fusion plasma.
An international team of researchers have, for the first time, glimpsed the ultrafast process of proton transfer following ionization of liquid water, shedding light on how radical cations separate from their electron partners, neutralize and subsequently drift about creating damage.
A protein newly identified as important in type 1 diabetes can delay onset of the disease in diabetic mice, providing a new target for prevention and treatment in people, according to research led by scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory and Indiana University School of Medicine.
The largest set of data yet from an underground experiment called CUORE sets more stringent limits on a theoretical ultra-rare particle process known as neutrinoless double-beta decay that could help to explain the abundance of matter over antimatter in the universe.
