Published Cleaner air with a cold catalytic converter
(via sciencedaily.com) Original source Although passenger vehicle catalytic converters have been mandatory for over 30 years, there is still plenty of room for improvement. For instance, they only work correctly when the engine is sufficiently hot, which is not always the case, especially with hybrid vehicles. Researchers have now developed an improved catalyst that can properly purify exhaust gases even at room temperature.
Published A 'spy' in the belly
(via sciencedaily.com) Original source To ensure that wounds remain tightly sealed in the abdomen after surgery, researchers have developed a patch with a sensor function. The polymer patch warns before the occurrence of dangerous leaks on sutures in the gastrointestinal tract take hold, while closes the areas on its own. A new material now enables a fast, easy and non-invasive leak diagnosis.
Published Nanomaterials: 3D printing of glass without sintering
(via sciencedaily.com) Original source A new process enables printing of nanometer-scale quartz glass structures directly onto semiconductor chips. A hybrid organic-inorganic polymer resin is used as feedstock material for 3D printing of silicon dioxide. Since the process works without sintering, the required temperatures are significantly lower. Simultaneously, increased resolution enables visible-light nanophotonics.
Published Photosynthesis, key to life on Earth, starts with a single photon
(via sciencedaily.com) Original source A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes.
Published For experimental physicists, quantum frustration leads to fundamental discovery
(via sciencedaily.com) Original source A team of physicists recently announced that they have discovered a new phase of matter. Called the 'chiral bose-liquid state,' the discovery opens a new path in the age-old effort to understand the nature of the physical world.
Published A baking soda solution for clean hydrogen storage
(via sciencedaily.com) Original source Scientists investigate the promising properties of a common, Earth-abundant salt.
Published A novel, completely solid, rechargeable air battery
(via sciencedaily.com) Original source Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as flammability, limited voltage, unstable reactants, and poor long-term cyclability and strength. Making advances in this field, researchers recently demonstrated an all-solid-state rechargeable air battery composed of a redox-active organic negative electrode and a proton-conductive polymer electrolyte.
Published New material transforms light, creating new possibilities for sensors
(via sciencedaily.com) Original source A new class of materials that can absorb low energy light and transform it into higher energy light might lead to more efficient solar panels, more accurate medical imaging and better night vision goggles.
Published Breaking through the limits of stretchable semiconductors with molecular brakes that harness light
(via sciencedaily.com) Original source A research team develops a highly stretchable and high-performance organic polymer semiconductor.
Published Mirror, mirror on the wall... Now we know there are chiral phonons for sure
(via sciencedaily.com) Original source New findings settle the dispute: phonons can be chiral. This fundamental concept, discovered using circular X-ray light, sees phonons twisting like a corkscrew through quartz.
Published Sustainable technique to manufacture chemicals
(via sciencedaily.com) Original source A newly published study details a novel mechanochemistry method that can produce chemicals using less energy and without the use of solvents that produce toxic waste.
Published Breakthrough: Scientists develop artificial molecules that behave like real ones
(via sciencedaily.com) Original source Scientists have developed synthetic molecules that resemble real organic molecules. A collaboration of researcher can now simulate the behavior of real molecules by using artificial molecules.
Published Physicists discover an exotic material made of bosons
(via sciencedaily.com) Original source Take a lattice -- a flat section of a grid of uniform cells, like a window screen or a honeycomb -- and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the top grid a twist so that you can see portions of the lower one through it. This new, third pattern is a moiré, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors.
Published Calculation shows why heavy quarks get caught up in the flow
(via sciencedaily.com) Original source Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain experimental results showing heavy quarks getting caught up in the flow of matter generated in heavy ion collisions.
Published Water molecules define the materials around us
(via sciencedaily.com) Original source A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.
Published More complex than expected: Catalysis under the microscope
(via sciencedaily.com) Original source Usually, catalytic reactions are analyzed by checking which chemicals go into a chemical reactor and which come out. But as it turns out, in order to properly understand and optimize catalysts, much more information is necessary. Scientists developed methods to watch catalytic reactions with micrometer resolution under the microscope -- and the process is much more complex than previously thought.
Published The problems with coal ash start smaller than anyone thought
(via sciencedaily.com) Original source Burning coal doesn't only pollute the air. The resulting ash can leach toxic chemicals into the local environments where it's kept. New research shows that the toxicity of various ash stockpiles relies heavily on its nanoscale structures, which vary widely between sources. The results will help researchers predict which coal ash is most environmentally dangerous.
Published Buckle up! A new class of materials is here
(via sciencedaily.com) Original source Would you rather run into a brick wall or into a mattress? For most people, the choice is not difficult. A brick wall is stiff and does not absorb shocks or vibrations well; a mattress is soft and is a good shock absorber. Sometimes, in designing materials, both of these properties are needed. Materials should be good at absorbing vibrations, but should be stiff enough to not collapse under pressure. A team of researchers from the UvA Institute of Physics has now found a way to design materials that manage to do both these things.
Published Finally solved! The great mystery of quantized vortex motion
(via sciencedaily.com) Original source Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.
Published Flat fullerene fragments attractive to electrons
(via sciencedaily.com) Original source Researchers have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprisingly retained and even enhanced some key chemical properties.
