How long do neutrons live? The answer could change how we think everything from the cosmos to coffee cups. Yet, scientists don't agree on the neutron longevity. The disagreement is fanned by the limitations of today's instruments. Now, a highly efficient detector is helping to resolve the puzzle.
Dramatic increases in ionization efficiencies for uranium, thorium, and palladium, which were made possible with RILIS, enable new studies relevant to nuclear fuels cycles, neutrino detection, and isotope production.
Pools of fatty molecules self-assemble around treated water droplets to create a cell-like bioreactor that could offer substantial advantages for carrying out complex synthesis processes.
Scientists discovered a material that exhibits an unprecedented mechanism for carbon dioxide capture-and-release with only small shifts in temperature. The material's structure closely resembles an enzyme found in plants that captures carbon dioxide for conversion into nutrients.
Scientists can now get a high-resolution view of a sample or the details of the first steps in ultra-fast processes, thanks to researchers at SLAC National Accelerator Laboratory's Linac Coherent Light Source.
Scientists correlated atomic-scale defects in graphene with a "bucket brigade" style mechanism that lets protons travel through the graphene. Demonstrating such a mechanism and the prospect for gating it could enable directing proton pathways for improved fuel cells and other uses.
Extremely water-repellant surfaces were fabricated that can withstand pressures that are 10 times greater than the average pressure a surface would experience resting in a room. The surfaces resist the infiltration of liquid into the nanoscale pockets, staying drier than similar coatings.
Researchers developed a new, protein-based system that can mine certain types of uranium from sea water with exceedingly high affinity and selectivity.
A suppression of strange quark production relative to up and down quark production had previously been noted; for the first time, the result has been verified when a single pair is produced.
Surprisingly, smaller particles colliding with large nuclei appear to produce tiny droplets of quark-gluon plasma. Recent results show that the tiny droplets behave like a liquid not the expected gas. The results support the case that these small particles produce tiny drops of the primordial soup.
Good news for those interested in accurately modeling combustion engines, scientists can now discriminate between previously unidentified radicals found in the early stages of the combustion process from similar compounds.
Light waves trapped on a metal's surface travel farther than expected. While the distance might seem quite small, it is far enough to possibly be useful in ultra-fast electronic circuits.
Scientists have - for the first time - precisely tracked the surprisingly rapid process by which light rearranges the outermost electrons of a metal compound and turns it into a catalyst. These details could help scientists predict and control the quick, early steps in reactions vital to renewable fuels.
Building better batteries means understanding the chemistry of acids and bases. Now, scientists found that when a strong acid is mixed with water, the negatively and positively charged parts create an unexpected structure.
Turning carbon dioxide from certain power plants into a more valuable chemical would reduce emissions while creating a revenue return. Scientists at the University of Pittsburgh derived a metal-free catalyst that does the trick without the need for expensive, extreme conditions.
With detection limits down to the zeptomolar range (about 600 molecules in a sample), a new technology can analyze the metabolic composition of individual microbial cells, as well as detect the presence of extremely low levels of environmental contaminants.
In all organisms, water's pH has a profound effect. Because the interaction of carbon dioxide and water explains the natural acidity of water and all accompanying reactions, it is considered a vital reaction by scientists. Researchers recently made a discovery about how dissolved dioxide bonds.
Scientists devised a new way of assembling ordered crystals made of nanoparticles. In this process, nanoparticles in the shape of cubes, octahedrons, and spheres coordinate with each other to build structures. The shapes are bound together by complementary DNA molecules on each type of particle.
Used in everything from cell phones to supercomputers, tiny electronic circuits contain transistors that generate performance-compromising heat. Thanks to a team working at the Molecular Foundry, circuit designers can "see" how temperatures change inside the circuits.
One Nanocrystal, Many Faces: Connecting the Atomic Surface Structures of Cerium Dioxide Nanocrystals to Catalysis
A promising catalyst seemed erratic in reducing the toxins released by burning gasoline and other such fuels. The catalyst's three different surfaces behaved differently. For the first time, researchers got an atomically resolved view of the three structures. This information may provide insights into why the surfaces have distinct properties.
For the first time, researchers have shown that momentum-hogging protons can exist in nuclei heavier than carbon.
Extremely small batteries built inside nanopores show that properly scaled structures can use the full theoretical capacity of the charge storage material. The batteries are part of assessing the basics of ion and electron transport in nanostructures for energy storage.
First identified more than 50 years ago, the sub-atomic particle called Lambda(1405) was routinely seen in experiments, yet two of its key characteristics were too difficult to measure. For the first time, scientists measured these descriptors: intrinsic angular momentum and parity.
Scientists built the most complete functional mapping of an entire family of cellulose-degrading enzymes, glycoside hydrolase family, to date.
For the first time, germanium nanowires have been deposited on indium tin oxide substrate by a simple, one-step process called electrodeposition. The nanowires produced by this method have outstanding electronic properties and can be used as high-capacity anode material for lithium-ion batteries; however, the nanowires were previously too expensive and difficult to produce. This process may resolve the cost issue.
