How well do wet masks contain droplets?
Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spr.....»»
Media failed to highlight the negative impact of single-use facemasks on the environment, says review
A multidisciplinary team from Bangor has shown how media messaging could have determined people's mask-wearing choices during the pandemic. This was based on a qualitative and quantitative review of British and Irish press coverage mentioning masks a.....»»
This 3D-printed plate lets food droplets magically move without being touched
New "computational food" design incorporates electrowetting on dielectric technology. "Dancing Delicacies": Researchers at Monash University created a special plate enhanced with electrodes that moves liquid droplets ar.....»»
New camera offers ultrafast imaging at a fraction of the normal cost
Capturing blur-free images of fast movements like falling water droplets or molecular interactions requires expensive ultrafast cameras that acquire millions of images per second. In a new paper, researchers report a camera that could offer a much le.....»»
The physics of saltwater taffy
Air bubbles, oil droplets are the primary factors, plus emulsifiers for extra chewiness Enlarge / Saltwater taffy is made by stretching and pulling the sticky candy base to create air bubbles for a fluffy and chewy confection. (c.....»»
Nano droplets go skiing at high temperatures
Currently, many (nano)structures are grown in layers, one above the other, but their ordering on the atomic scale is generally far from perfect. Researchers from the University of Twente have aimed for a better understanding of these processes that c.....»»

Scientists zoom in on the Asian monsoon season using satellite data
Scientists from Tokyo Metropolitan University and other institutes have studied new satellite data showing the diameter of rain droplets and the distribution of heavy ice in the atmosphere worldwide. They focused on the Asian monsoon region, finding.....»»
Unlocking the mysteries of freezing in supercooled water droplets
Clouds are a lot cooler than you might think. In fact, scientists might say they're super cool because they're made up of millions of supercooled water droplets, droplets that have been cooled below the freezing point but haven't yet turned into ice......»»
Why tiny metal droplets take longer to solidify into glass: Fundamental observation in materials science
Most people who hear the word 'glasses' will probably think of drinking glasses or corrective eyewear. Hardly anyone will think of metals. But metallic glasses, or 'amorphous metals' as they are also known, are playing an increasingly important role.....»»
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......»»
Research offers insights on the prevalence of drizzle in marine stratocumulus clouds
Drizzle is light precipitation in droplets smaller than rain drops. Detecting drizzle in its early stages in marine stratocumulus clouds is important for studying how water in these clouds becomes rainfall. These clouds form off the west coasts of la.....»»

How to protect your pets from wildfire smoke
The U.S. Northeast is currently smothered in smoke, as Canadian wildfires rage in what may be its worst fire year yet. This has sent air quality plummeting, with residents donning N95 masks and staying indoors in order to reduce how much of the dange.....»»
Insect wings could inspire new self-cleaning technologies
Fresh insights into how insects use water droplets to wash dirt and pollutants from their bodies could help improve the performance of self-cleaning devices, a study suggests......»»
Study finds shoppers" masking compliance influenced their in-store behaviors
As the coronavirus began to spread globally, face masks were recommended in public settings to protect against transmission, and compliance varied significantly. In a new study of people shopping in a large Chinese store in early 2020, researchers ex.....»»
