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.....»»
Scientists develop high-precision droplet printing platform for single cell phenotype screening
With the rapid development of genome synthesis and editing technologies, droplet-based single-cell phenotype screening has become increasingly important. However, precise and high-throughput distribution of target droplets into specific macroscopic m.....»»
Bioinspired hydrogel pattern enhances atmospheric water harvesting via directional droplet steering
The water in the air originates from both natural and forced evaporation, with condensation being the final and crucial step in water harvesting. Condensation involves nucleation, growth, and shedding of water droplets, which are then collected......»»
Team expands research of water droplet interfaces that offer the secret ingredient for building life
R. Graham Cooks, the Henry B. Hass Distinguished Professor of Chemistry, and his postdoctoral researcher Lingqi Qiu have experimental evidence that the key step in protein formation can occur in droplets of pure water, and have recently published the.....»»
How winter storms stress San Luis Obispo County elephant seals in the midst of birthing season
The late December morning rain left droplets on Christine Heinrichs' glasses as she stood among a throng of tourists and watched dozens of elephant seals tussle and sleep on a beach just south of the Piedras Blancas Light Station......»»
Mysterious missing component in the clouds of Venus revealed
What are the clouds of Venus made of? Scientists know it's mainly made of sulfuric acid droplets, with some water, chlorine, and iron. Their concentrations vary with height in the thick and hostile Venusian atmosphere. But until now they have been un.....»»
Scientists create tunable shells to encapsulate tiny droplets
Scientists at the Indian Institute of Science (IISc) have developed a novel technique to encapsulate liquid droplets used for various applications, including single crystal growth and cell culture......»»
Researchers observe a hallmark quantum behavior in bouncing droplets
In our everyday classical world, what you see is what you get. A ball is just a ball, and when lobbed through the air, its trajectory is straightforward and clear. But if that ball were shrunk to the size of an atom or smaller, its behavior would shi.....»»
Water and electricity: Charge effects can influence flowing droplets
From precise inkjet printing to clear vision through spectacle lenses—the influence of droplets and their movement shapes numerous areas of our daily lives. While droplets should remain precisely in place on inkjet prints, it is desirable that they.....»»
Novel measurement technique for fluid-mixing phenomena using selective color imaging method
A novel measurement technique has been developed to visualize the fluid flow and distribution within two droplets levitated and coalesced in space using fluorescence-emitting particles. This technique enabled the estimation of fluid motion within eac.....»»
Masks are back, construction banned and schools shut as toxic air engulfs New Delhi
A toxic blanket of grey smog hangs over New Delhi's monuments and high-rises. Schools have been ordered shut and construction banned. People are back to wearing masks......»»
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.....»»
7 Face Masks Your Kids May Actually Wear (2023)
If your child is at high risk or if community transmission rates are high, you may want them to wear face masks. These are the styles my little ones will tolerate......»»
ComplyCube Field Redaction removes sensitive fields from documents
ComplyCube enhanced its Document Checks solution with automated Field Redaction capabilities. This feature systematically masks sensitive Personal Identifiable Information (PII) fields, such as the Dutch BSN, to assist businesses with global data pri.....»»
Scientists prepare ISS experiment to study how droplets form in space
Dropcoal, short for drop coalescence, is a research project that studies how droplets form in space and on Earth. The results will grant insights into raindrop and cloud formation, fuel combustion and interactions between materials, all with broad im.....»»
The physics of fat droplets reveal DNA danger
