Published Ultracold atoms dressed by light simulate gauge theories
(via sciencedaily.com) Researchers have used the coldest systems in the universe to realize in the laboratory gauge theories, key models of modern physics that describe the fundamental forces of Nature and the behavior of complex quantum materials.
Published Researchers discover major roadblock in alleviating network congestion
(via sciencedaily.com) Researchers discovered that congestion control algorithms designed to ensure multiple users sending data over a network do so fairly are actually unable to avoid situations where some users are hogging all the bandwidth.
Published A paper battery with water switch
(via sciencedaily.com) A team of researchers has developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics -- such as smart labels for tracking objects, environmental sensors and medical diagnostic devices -- and minimize their environmental impact.
Published Magnetic quantum material broadens platform for probing next-gen information technologies
(via sciencedaily.com) Scientists have used neutron scattering to determine whether a specific material's atomic structure could host a novel state of matter called a spiral spin liquid. By tracking tiny magnetic moments known as 'spins' on the honeycomb lattice of a layered iron trichloride magnet, the team found the first 2D system to host a spiral spin liquid.
Published Graphene scientists capture images of atoms 'swimming' in liquid
(via sciencedaily.com) Graphene scientists have created a novel 'nano-petri dish' using two-dimensional (2D) materials to create a new method of observing how atoms move in liquid.
Published Bioinspired protein creates stretchable 2D layered materials
(via sciencedaily.com) Nature creates layered materials like bone and mother-of-pearl that become less sensitive to defects as they grow. Now researchers have created, using biomimetic proteins patterned on squid ring teeth, composite layered 2D materials that are resistant to breaking and extremely stretchable.
Published Buckyballs on gold are less exotic than graphene
(via sciencedaily.com) C60 molecules on a gold substrate appear more complex than their graphene counterparts, but have much more ordinary electronic properties. This is now shown by measurements with ARPES at BESSY II and detailed calculations.
Published New model predicts how temperature affects life from quantum to classical scales
(via sciencedaily.com) A new theory explains how every process depends on temperature. This theory could help researchers make accurate predictions in a range of areas, including biological responses to climate change, the spread of infectious diseases, and food production.
Published Go with the flow: New findings about moving electricity could improve fusion devices
(via sciencedaily.com) Researchers have found that updating a mathematical model to include a physical property known as resistivity could lead to the improved design of doughnut-shaped fusion facilities known as tokamaks.
Published New research furthers understanding of the electronic structure of graphite
(via sciencedaily.com) Graphite is an incredibly important, versatile mineral, with uses spanning industries. Graphite is an essential component of many batteries, including lithium-ion batteries, and demand is only increasing as new technology is developed. Surprisingly, no spectroscopic studies have so far accurately measured the electronic states of the surface and the edge of graphite from a microscopic point of view. Indeed, the improvement in battery performance depends largely on the control of the characteristics of the graphite at the tip.
Published Researcher uses graphene for same-time, same-position biomolecule isolation and sensing
(via sciencedaily.com) New research has overcome a major challenge to isolating and detecting molecules at the same time and at the same location in a microdevice. The work demonstrates an important advance in using graphene for electrokinetic biosample processing and analysis and could allow lab-on-a-chip devices to become smaller and achieve results faster.
Published Research team accelerates imaging techniques for capturing small molecules' structures
(via sciencedaily.com) A new research effort is accelerating imaging techniques to visualize structures of small molecules clearly -- a process once thought impossible. Their discovery unleashes endless potential in improving everyday life applications -- from plastics to pharmaceuticals.
Published Flashing creates hard-to-get 2D boron nitride
(via sciencedaily.com) Original source Chemists use their flash Joule heating process to synthesize 2D flakes of boron nitride and boron carbon nitride, highly valued for lending thermal and chemical stability to compounds.
Published Thin mica shows semiconducting behavior, say scientists in new study
(via sciencedaily.com) Original source Muscovite mica (MuM) is a highly stable mineral that is commonly used as an insulator. However, the electrical properties of single-layer and few-layered MuM are not well understood. Now, a group of researchers reports and explains unusually high conductivity in MuM flakes that are only a few molecule layers thick. Their findings could open doors to the development of two-dimensional electronic devices that are robust against harsh environments.
Published Advocating a new paradigm for electron simulations
(via sciencedaily.com) Researchers improve a widely used simulation method for high-performance computing clusters.
Published A new model sheds light on how we learn motor skills
(via sciencedaily.com) Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration -- that is, increased variability in movements -- is important when learning a new task. These results may lead to improved motor rehabilitation in patients after injury or disease.
Published Math model predicts efficacy of drug treatments for heart attacks
(via sciencedaily.com) Researchers used mice to develop a mathematical model of a myocardial infarction. The new model predicts several useful new drug combinations that may one day help treat heart attacks, according to researchers.
Published New, highly tunable composite materials--with a twist
(via sciencedaily.com) Mathematicians have found that they can design a range of composite materials from moiré patterns created by rotating and stretching one lattice relative to another. Their electrical and other physical properties can change --s ometimes quite abruptly, depending on whether the resulting moiré patterns are regularly repeating or non-repeating.
Published Study explores the promises and pitfalls of evolutionary genomics
(via sciencedaily.com) A new study examines mathematical models designed to draw inferences about how evolution operates at the level of populations of organisms. The study concludes that such models must be constructed with the greatest care, avoiding unwarranted initial assumptions, weighing the quality of existing knowledge and remaining open to alternate explanations.
Published Agriculture tech use opens possibility of digital havoc
(via sciencedaily.com) Wide-ranging use of smart technologies is raising global agricultural production but international researchers warn this digital-age phenomenon could reap a crop of another kind -- cybersecurity attacks. Complex IT and math modelling has highlighted the risks.
