Ultrasound-based microfluidic manipulation platform for airborne droplets
As science races toward automation and quick experiments, it is sometimes required to concurrently handle small amounts of liquids (droplets), from picoliters to microliters. Moreover, droplet jumping is required when transporting droplets to distant.....»»
Droplet levitation: A new way to explore airborne viruses and microorganisms
Self-sustained levitation of millimeter-sized droplets was recently discovered by researchers at Tyumen State University, in Russia, during an experiment to select combinations of immiscible liquids, which don't form homogeneous mixtures......»»
Breaking into tears with microrheology to design custom eye drops
Compared to artificial tears, or eye drops, human tears are significantly more complex liquids, with a wide range of components including lipids, carbohydrates, proteins, water, and salt. It is this complex mixture that gives tears the perfect thickn.....»»
Unraveling the super-complex structure of supercooled liquids
When cooled to their freezing point, most liquids become solids or crystallize. In other words, the molecules arrange themselves in a perfectly ordered fashion, which physicists call a crystal. Supercooled liquids are different; they do not form such.....»»
Silicon Valley escalates the battle over returning to the office

Toward the realization of chiral spin liquids and non-Abelian anyons in quantum simulators
Chiral spin liquids are one of the most fascinating phases of matter ever imagined by physicists. These exotic liquids exhibit quasi-particles known as non-Abelian anyons that are neither bosons nor fermions, and whose manipulation could allow for th.....»»
Twitter accuses Microsoft of refusing to pay for tweets and abusing its data access
Twitter is accusing Microsoft of abusing its data access privileges to its platform, in the latest sign of the social network's owner Elon Musk igniting a feud between the two tech companies......»»
Peanut butter is a liquid—the physics of this and other unexpected fluids
Those Transportation Security Administration requirements are drilled into every frequent flyer's head: You can carry on liquids that are only less than 3.4 ounces (100 milliliters) in volume each......»»
Finding the best liquids to maximize antioxidant content in spinach smoothies
Different market products give very different results when it comes to liberating the antioxidant lutein from spinach in smoothies. Researchers at Linköping University, Sweden, have examined 14 common dairy and plant-based products and found that on.....»»
Reviewing and evaluating recent electrochemical carbon dioxide reduction with ionic liquids
The increasing CO2 emission as the chief culprit causing many environmental problems could be addressed via electrochemical CO2 reduction (CO2R) to the added-value carbon-based chemicals. Due to the unique advantages, ionic liquids (ILs) have been wi.....»»

Writing in the Journal of Molecular Liquids, a team led by Professor Aravind Vijayaraghavan based in the National Graphene Institute (NGI) have produced three-dimensional particles made of graphene, of many interesting shapes, using a variation of th.....»»
Researchers develop elastic material that is impervious to gases and liquids
An international team of researchers has developed a technique that uses liquid metal to create an elastic material that is impervious to both gases and liquids. Applications for the material include use as packaging for high-value technologies that.....»»
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.....»»
