Engineers at the University of Pennsylvania have discovered that foams exhibit internal motion resembling deep learning in AI systems. The study suggests a common mathematical principle underlying both foams and AI training, with implications for designing adaptive materials and understanding biological structures.
Researchers investigate beer foams to understand their stability, finding that different types of beers use unique mechanisms to hold thin films together. The study provides valuable insights for creating stable foams with applications in oil separation, firefighting chemicals, and more.
Researchers developed certified biodegradable and recyclable multi-purpose foams from cellulose, replacing oil-based products. The foams have potential applications in the automotive sector for crash impact energy management and construction as an insulating material.
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.
Researchers at the University of Gothenburg developed a bicycle helmet with improved shock-absorbing material that utilises auxetic metastructures. The new helmet design provides better protection against head injuries, is lighter, and can be customised to individual head shapes using 3D printing.
Researchers found that microplastics increase the height and stability of sea foam, particularly when part of smaller breaking waves. This positive effect reflects sunlight, potentially lowering ocean temperatures and driving more cloud formation.
Researchers from Tokyo Metropolitan University created a new model to study the transmission of forces through amorphous solids like concrete and cement. They found that areas between hard regions 'harden' to produce elongated force chains, leading to softer materials with more uniform stiffness.
Researchers found that foam spreading changes with scraping speed and surface affinity, leading to different patterns on hydrophobic and hydrophilic surfaces. The study's findings apply to various soft materials, including foams, paints, and coatings.
Researchers from the University of Warsaw explore how kitchen phenomena lead to breakthroughs in biomedicine and nanotechnology. They describe bubbles in champagne, Leidenfrost effect, and surface tension, revealing surprising connections between food science and scientific discoveries.
Researchers developed a multiphase solver to predict beer foam features, including patterns, heights, stability, and volume fractions. The study found that foam generation is sensitive to temperature and pressure, with higher temperatures producing more foam.
Researchers from Tokyo Metropolitan University found that a foam's liquid amount and extent determine its draining mechanism. They identified universal thresholds for different foams, promising clear design principles for new materials.
A Princeton University study reveals a type of foam can block specific wavelengths of light while allowing others to pass through, creating a photonic band gap. This property has the potential to control the flow of electrons in materials and could lead to breakthroughs in telecommunications.
Researchers found that capillary forces from soap foam induce pressure gradients near the container walls, reducing sloshing motion. The dampening effect happens faster than expected exponential decay, causing the waves to stop after a finite time.
