Published Mirror, mirror on the wall... Now we know there are chiral phonons for sure



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



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



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 South Africa, India and Australia shared similar volcanic activity 3.5 billion years ago



The Daitari greenstone belt shares a similar geologic make-up when compared to the greenstones exposed in the Barberton and Nondweni areas of South Africa and those from the Pilbara Craton of north-western Australia.
Published Physicists discover an exotic material made of bosons



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



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



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 Bubble, bubble, more earthquake trouble? Geoscientists study Alaska's Denali fault



Geochemists report findings from collected and analyzed helium and carbon isotopic data from springs along a nearly 250-mile segment of Alaska's Denali Fault. The fault's mantle fluid flow rates, they report, fall in the range observed for the world's other major and active strike-slip faults that form plate boundaries.
Published More complex than expected: Catalysis under the microscope



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



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



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 Below the surface: Researchers uncover reasons to rethink how mountains are built



A study suggests that the answers to how and why mountains form are buried deeper than once thought. Clues in the landscape of southern Italy allowed researchers to produce a long-term, continuous record of rock uplift, the longest and most complete record of its kind.
Published Researchers cultivate archaea that break down crude oil in novel ways



The seafloor is home to around one-third of all the microorganisms on the Earth and is inhabited even at a depth of several kilometers. Only when it becomes too hot does the abundance of microorganisms appear to decline. But how, and from what, do microorganisms in the deep seafloor live? How do their metabolic cycles work and how do the individual members of these buried communities interact? Researchers have now been able to demonstrate in laboratory cultures how small, liquid components of crude oil are broken down through a new mechanism by a group of microorganisms called archaea.
Published Finally solved! The great mystery of quantized vortex motion



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



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.
Published Producing large, clean 2D materials made easy



An international team of surface scientists has now developed a simple method to produce large and very clean 2D samples from a range of materials using three different substrates.
Published Researchers finds a way to reduce the overheating of semiconductor devices



Scientists have identified a method for improving the thermal conductivity of thin metal films in semiconductors using surface waves for the first time in the world.
Published Petit-spot volcanoes involve the deepest known submarine hydrothermal activity, possibly release CO2 and methane



Underwater volcanism and its hydrothermal activity play an important role in marine biogeochemical cycles, especially the carbon cycle. But the nature of hydrothermal activity at 'petit-spot' volcanoes have not been revealed at all. Now, scientists reveal that petit-spot hydrothermal activity occurs on the deepest seafloor known to date and could release carbon dioxide (CO2) and methane, which may have implications for the global carbon cycle.
Published X-rays visualize how one of nature's strongest bonds breaks



The use of short flashes of X-ray light brings scientists one big step closer toward developing better catalysts to transform the greenhouse gas methane into a less harmful chemical. The result reveals for the first time how carbon-hydrogen bonds of alkanes break and how the catalyst works in this reaction.
Published You can make carbon dioxide filters with a 3D printer



Researchers demonstrated that it's possible to make carbon dioxide capture filters using 3D printing.
