Researchers at University of Pennsylvania discover red blood cells contribute to clot contraction, shrinking and stabilizing blood clots. The finding opens door to new strategies for studying and treating clotting disorders, such as excessive bleeding or dangerous clots like those seen in strokes.
Researchers from Tokyo Metropolitan University solved the drainage mystery in foams by discovering the pressure needed to rearrange bubbles sets the limit for liquid to drain out. The team found that dynamics play a crucial role in understanding soft materials and designing better foam products.
Lynne McLandsborough's research offers a solution to the sticky sanitation issue in peanut butter and chocolate industries, improving food safety and reducing bacterial illness outbreaks. Her patent-pending method uses a water-in-oil emulsion to kill 99.9999% of Salmonella bacteria.
A recent study identified orthophosphate as a contaminant in some antiscalants that promotes bacterial growth, while HEDP-based antiscalants showed no biofouling effect. The research aims to develop simple low-tech tests for desalination plants to reduce energy consumption and extend membrane lifespan.
Scientists at Osaka University have developed an ultrathin silicon membrane with arrays of nanopores that can harness osmotic flow to generate electricity from seawater. The device achieved peak power efficiency of 400 kW/m² and demonstrated optimal configuration for best power generation.
Researchers from the Institute of Physical Chemistry, Polish Academy of Sciences, have developed a novel polymer-based solution that enables easy delivery of large molecules to cells. By applying hypertonic solutions, they can induce osmotic stress and relax the cell membrane, allowing for precise control over molecule transfer.
A UNIGE team discovered that cells in curved tissues swell by 50% before returning to normal, opening avenues for in vitro organ culture. This active phenomenon can be harnessed to control spontaneous growth of organoids and develop new materials with volume increase upon folding.
Researchers discovered that a specific osmolyte causes kidney cells to undergo an EMT transformation, leading to renal failure. The team found a way to prevent this change by arresting focal adhesion rearrangement, suggesting a new approach to enhance therapeutic value of common osmolytes.
Researchers have discovered that squids can not only change the color of their skin but also its brightness, achieved through the action of 'osmotic motors' driven by reflectin proteins. This complex mechanism allows for a wide range of iridescent colors and brightness levels.
Researchers have developed thinner shells for delivering therapeutic biomolecules, reducing osmotic pressure required for safe release. The lopsided microcapsules can burst at lower pressures, making them suitable for controlled release in medicine and other fields.
Researchers propose active sieving to fine-tune filtration systems for improved separation abilities. The technology could also filter molecules based on movement dynamics, opening a new avenue in membrane science.
A recent study from MIT found that pressurization doesn't exacerbate membrane fouling in reverse osmosis (RO) systems. Researchers devised a method to isolate pressure's effects and discovered no impact on fouling rates or cleaning outcomes.
Researchers discovered that oversized microgel particles shrink to match smaller neighbors due to shared counter ions, increasing osmotic pressure and expelling solvent. This mechanism allows for the formation of crystalline structures with point defects eliminated, unlike hard particle systems.
Researchers used microfluidic devices to trap bacterial cells and bathe them in different solutions, revealing that cell walls grow regardless of external pressures. The study's findings challenge the prevailing wisdom on osmotic shock, which may lead to new strategies for fighting bacterial diseases.
Researchers develop a physical model for sap exudation, attributing mechanism to pressure and volume changes in tree's vascular tissue. The model incorporates dynamics of thawing sap, dissolving gas bubbles, and osmotic pressure gradient.
Researchers created a 3D model of a European beech tree to study the changes in the trunk's structure when water moves through it. The study reveals that the sap is in a pressurized situation, expanding in radial direction during positive pressure and contracting during negative pressure.
Biologists discovered a common corn fungus can launch its spores at incredible speeds of up to 80 miles an hour. The spore travels only two-tenths of an inch before landing due to atmospheric drag, which plays a significant role in the physics of scaling.
Scientists have identified a molecule called VR-OAC that senses osmotic pressure in vertebrates, including humans. This discovery may provide insight into the biological basis of inner ear function and the sense of touch.
