Published Robot 'chef' learns to recreate recipes from watching food videos
(via sciencedaily.com) Original source Researchers have trained a robotic 'chef' to watch and learn from cooking videos, and recreate the dish itself.
Published Researchers demonstrate secure information transfer using spatial correlations in quantum entangled beams of light
(via sciencedaily.com) Original source Researchers have demonstrated the principle of using spatial correlations in quantum entangled beams of light to encode information and enable its secure transmission.
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.
Published Producing large, clean 2D materials made easy
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 The 'breath' between atoms -- a new building block for quantum technology
(via sciencedaily.com) Original source Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.
Published X-rays visualize how one of nature's strongest bonds breaks
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source Researchers demonstrated that it's possible to make carbon dioxide capture filters using 3D printing.
Published A protein mines, sorts rare earths better than humans, paving way for green tech
(via sciencedaily.com) Original source Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth's crust and from one another. Scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or 'dimerize,' when it is bound to certain rare earths, but prefer to remain a single unit, or 'monomer,' when bound to others.
Published First X-ray of a single atom
(via sciencedaily.com) Original source Scientists have taken the world's first X-ray SIGNAL (or SIGNATURE) of just one atom. This groundbreaking achievement could revolutionize the way scientists detect the materials.
Published Under pressure: Foundations of stellar physics and nuclear fusion investigated
(via sciencedaily.com) Original source Research using the world's most energetic laser has shed light on the properties of highly compressed matter -- essential to understanding the structure of giant planets and stars, and to develop controlled nuclear fusion, a process that could harvest carbon-free energy.
Published Crossing the ring: New method enables C-H activation across saturated carbocycles
(via sciencedaily.com) Original source Chemists add another powerful tool to their 'molecular editing' toolkit for crafting pharmaceuticals and other valuable compounds.
Published Source-shifting metastructures composed of only one resin for location camouflaging
(via sciencedaily.com) Original source Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.
Published Robot centipedes go for a walk
(via sciencedaily.com) Original source Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Published Absolute vs. relative efficiency: How efficient are blue LEDs, actually?
(via sciencedaily.com) Original source The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found that the assumption of always perfect IQE is wrong: the IQE of an LED can be as low as 27.5%.
Published Emergence of solvated dielectrons observed for the first time
(via sciencedaily.com) Original source Scientists generate low-energy electrons using ultraviolet light.
Published Protein-based nano-'computer' evolves in ability to influence cell behavior
(via sciencedaily.com) Original source The first protein-based nano-computing agent that functions as a circuit has been created. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.
Published Effective as a collective: Researchers investigate the swarming behavior of microrobots
(via sciencedaily.com) Original source Miniaturization is progressing rapidly in just any field and the trend towards the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted sites in the body. Statistical physics can contribute to the foundations for the development of such technologies.
