High-speed camera captures a water jet's splashy impact as it pierces a droplet

Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy exercise could help scientists identify ways to inject fluids such as vaccines through ...

New metal-free hydrogel electrodes flex to fit the body's many shapes, avoiding damage to organs

Arrays of metal electrodes are often used in medical procedures that require monitoring or delivering electrical impulses in the body, such as brain surgery and epilepsy mapping. However, the metal and plastic materials that ...

A new 'twist' to break viscoelastic liquid bridges

If you've ever tried to lift a pizza slice covered in hot, melted cheese, you've no doubt encountered the long, cheesy strings that bridge one pizza slice from the next. Keep lifting the pizza slice and these cheese bridges ...

Warm ice may fracture differently than cold ice

Researchers at Aalto University have found strong evidence that warm ice—that is, ice very close in temperature to zero degrees Celsius—may fracture differently as compared to the kinds of ice typically studied in laboratories ...

Droplets perform daredevil feats on gel surfaces

Welcome to the amazing world of soft substrates. These materials are made of silicon gels and have the same texture as panna cotta—but without the delicious flavor. They are used in a range of applications, especially in ...

New mathematical model: How dangerous bacteria form colonies

It can be observed every time you take a shower: Small droplets of water join together to form larger and larger drops—until they are so heavy that they run down the wall. Scientists call this daily-life phenomenon coalescence—which ...

Predicting delayed instabilities in viscoelastic solids

It is presently challenging to determine the stability of viscoelastic structures since seemingly stable conformations may gradually creep (plastic deformation of a material under stress as a function of time) until their ...

Enhanced liquid repellence through flexible microstructures

Artificial surfaces that can repel liquids have attracted significant attention across scientific and industrial platforms to create functional topological features. But the role of the underlying structures that are in contact ...
