Non-coalescence and in-plane momentum generation in sessile droplet clusters
Intuitively, droplets in proximity merge when brought into contact. However, under certain conditions, they may not coalesce due to the entrapment of an interstitial gas film. Droplet non-coalescence has so far been observed in various scenarios, such as during interactions between droplets moving with relative bulk velocity, droplets with opposite charges and size differences, and Leidenfrost droplets due to continuous vapor generation. Although non-coalescence has been reported for droplets o…

new book about medicine history, "droplets" theory etc
"Science writer Carl Zimmer’s latest book is a brilliant history of medicine that takes us from Louis Pasteur’s germ theory of the 19th century to present day. Along the way, it offers an anthropological study of medical culture — a culture capable of ignoring science when it wants to. ...
"If COVID-19 spread in droplets, then it was worthwhile to keep people two metres apart, to put up plexiglas barriers around checkout stands, and make supermarket aisles one-way. Sanitizing countertops could break the chain of infection.
"But if COVID-19 was airborne, all those measures were pointless."
Bit of an exaggeration in that part of the article. The 2m distance does put you outside the densest clouds of exhaled breath, and sanitising countertops helps against other diseases. But yeah. A lot of effort wrongly expended due to the prevailing myth.

DiaryPlay: AI-Assisted Authoring of Interactive Vignettes for Everyday Storytelling
An interactive vignette is a popular and immersive visual storytelling approach that invites viewers to role-play a character and influences the narrative in an interactive environment. However, it has not been widely used by everyday storytellers yet due to authoring complexity, which conflicts with the immediacy of everyday storytelling. We introduce DiaryPlay, an AI-assisted authoring system for interactive vignette creation in everyday storytelling. It takes a natural language story as inpu…

Impact of Spinning Droplets onto Superhydrophobic Surfaces: Asymmetric Tumbling Rapid Rebound
The impact dynamics of spinning droplets onto superhydrophobic surfaces was studied by using Volume-of-Fluid simulations, covering broad ranges of Weber number ($We$) and dimensionless angular velocity ($\mathitΩ$). The omputational results were validated by high-speed imaging experiments, with particular focus on the types of rebound, asymmetric deformation, and droplet-wall contact time. Results show that, the spinning motion of droplets leads to two novel rebound scenarios. Specificially, t…

Leaf-inspired rain-energy harvesting device
We study a rain-powered energy-harvesting device inspired by the natural impact of raindrops on leaves. In nature, a raindrop striking a leaf at high speed causes it to deform and vibrate. Inspired by this, our device uses an elastic beam coupled with a piezoelectric material to convert mechanical vibrations from droplet impacts into electrical energy. We conduct experiments to analyze how beam length, droplet impact location, and residual droplet mass affect energy conversion. Our results, sup…

High-throughput controlled droplets generation through a flow-focusing microchannel in shear-thinning fluids
This study presents a three-dimensional transient computational fluid dynamics simulation of droplet generation in a flow-focusing microfluidic device using the Coupled Level Set and Volume of Fluid method for interface capturing. We systematically investigated the effects of shear-thinning non-Newtonian fluids, specifically carboxymethyl cellulose solutions, on the generation of mineral oil droplets. The rheological properties of carboxymethyl cellulose were analyzed at concentrations of 0.1%,…

Numerical analysis of controlled droplet formation surrounded by shear-thinning fluid in a co-flow microfluidic device
In this work, we used a coupled level set and volume of fluid (CLSVOF) computational method for studying the generation of microdroplets in a two dimensional circular co-flow microfluidic device. The fundamental understanding of shear thinning behavior on controlled droplet formation in a microchannel is systematically investigated. Droplet generation and dynamics are controlled by altering the operating conditions and fluid properties, such as CMC solution concentration, both fluids flow rates…
