Igniting plasmas in liquids
Physicists of Ruhr-Universität Bochum (RUB) have taken spectacular pictures that allow the ignition process of plasma under water to be viewed and tracked in real time. Dr. Katharina Grosse has provided the first data sets with ultra-high temporal r.....»»
Solids that are also liquids: Elastic tensors of superionic materials
Understanding the elastic properties of solid-state ionic conductors, also known as superionic materials, is a crucial challenge in developing the solid-state electrolytes (SSEs) that could replace the liquid organic electrolytes used today, thereby.....»»
New strategy uses ionic liquids to change laser colors with ease
Lasers are intense beams of colored light. Depending on their color and other properties, they can scan your groceries, cut through metal, eradicate tumors, and even trigger nuclear fusion. But not every laser color is available with the right proper.....»»
Interfaces play important role in condensate behavior
Before mixing an oil-and-vinegar-based salad dressing, the individual drops of vinegar are easily seen suspended in the oil, each with a perfectly circular boundary that delineates the two liquids. In the same way, our cells contain condensed bundles.....»»
Demixing behavior of disks rotating in opposite directions can be explained by turbulent effects
As anyone who drinks their coffee with milk knows, it's much easier to mix liquids together than to separate them. In fact, the second law of thermodynamics would seem to dictate that a mixture would never be able to separate again if there are no at.....»»
New spectroscopy technique improves trace element detection in liquid
Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis technology that has been well developed for trace element analyses in gases, liquids, and solids. It uses a high-power laser pulse to elicit short-lived, high-temperature plasma.....»»
The world"s largest turbulence simulation unmasks the flow of energy in astrophysical plasmas
Researchers have uncovered a previously hidden heating process that helps explain how the atmosphere that surrounds the sun called the "solar corona" can be vastly hotter than the solar surface that emits it......»»
Study observes Luttinger liquid behavior in a quasi-2D system
Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These "liquids" and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, such as blue bronze A0......»»
First-of-its-kind experimental evidence defies conventional theories about how plasmas emit or absorb radiation
Most people are familiar with solids, liquids, and gases as three states of matter. However, a fourth state of matter, called plasmas, is the most abundant form of matter in the universe, found throughout our solar system in the sun and other planeta.....»»
Observation of a new type of self-generated current in magnetized plasmas
Nuclear fusion has drawn attention in the era of carbon neutrality because it produces no carbon emission or radioactive waste......»»
Electrons with Planckian scattering in strange metals follow standard rules of orbital motion in a magnet
Strange metals, or non-Fermi liquids, are distinct states of matter that have been observed in different quantum materials, including cuprate superconductors. These states are characterized by unusual conductive properties, such as a resistivity that.....»»
Electrons that flow like liquids pave the way for robust quantum computers
Quantum computers, which can perform calculations much faster than traditional computers, have a big problem: They are prone to data storage and processing errors caused by disturbances from the environment like vibrations and radiation from warm obj.....»»
Studying phase separation in liquids at microscopic level when energy is added
A team of physicists at the University of California at Santa Barbara has discovered some of the dynamics involved with active liquid surfaces at the microscopic level when energy is added. In their paper published in the journal Science, the group d.....»»
Research makes physics of glass formation clearer
The fragility of liquid—that is, how the fluidity of a liquid changes with temperature—has long been believed to be a key factor in understanding liquids and also how they form into glasses. However, a reliable way to measure fragility in liquids.....»»
Harvesting resources on Mars with plasmas
An international team of researchers came up with a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment, and it may deliver high r.....»»
Matter at extreme conditions of very high temperature and pressure turns out to be remarkably simple and universal
Scientists at Queen Mary University of London have made two discoveries about the behavior of "supercritical matter"—matter at the critical point where the differences between liquids and gases seemingly disappear......»»
Complex coacervate droplets as a model material for studying the electrodynamic response of biological materials
Manipulating solid particles of a few micrometers in size using an electric field has been of great interest to physicists. These controllable particles can be assembled into dynamic chains that can effectively control the flow of liquids in thin tub.....»»
Novel method examines the gas-liquid interface in new detail
The interface between gases and liquids is found throughout nature. It is also important to many industrial processes. To improve understanding of the gas-liquid interface, researchers have developed an apparatus to study reactions between gas molecu.....»»
Researchers propose neuromorphic computing with optically driven nonlinear fluid dynamics
Sunlight sparkling on water evokes the rich phenomena of liquid-light interaction, spanning spatial and temporal scales. While the dynamics of liquids have fascinated researchers for decades, the rise of neuromorphic computing has sparked significant.....»»
Two-dimensional ionic liquids to effectively capture carbon dioxide
In the context of global concerns about climate change and greenhouse gas control, a new technology for CO2 capture, utilization, and storage has attracted broad attention......»»
