Sometimes in shallow water, a type of wave can form that is much more stable than ordinary waves. Called solitons, these phenomena emerge as solitary waves and can travel long distances while maintaining their shape and speed, ...
(Phys.org)—Scientists have demonstrated that pinwheel-shaped microgears floating on a liquid surface can rotate at speeds of up to 300 r.p.m. when illuminated by an ordinary LED. This light-driven motion, which arises because ...
(Phys.org)—Single-walled carbon nanotubes may one day replace the silicon in electronics, but in order to do so, the nanotubes must be aligned in dense arrays for optimal performance. So far, the highest nanotube density ...
Titan's "magic islands" are likely floating chunks of porous, frozen organic solids, a new study finds, pivoting from previous work suggesting they were gas bubbles. The study was published in Geophysical Research Letters.

Janus adhesive hydrogels hold promising applications across health care fields. Nevertheless, a simple method to synthesize the material had yet to be bioengineered in the lab.
Early in the pandemic, Víctor Ortega-Jiménez was exploring creeks near his home and observing springtails. The organisms are the most abundant non-insect hexapods on earth, and Ortega-Jiménez suspected their avoidance ...

Droplet microfluidics provide a robust platform to synthesize and functionalize micro- and nanoparticles in a range of applications, including drug delivery, screening, lab-on-a-chip and organ-on-a-chip applications, across ...
Emulsions of oil-based pesticides are widely used in agriculture, although they are a major environmental and health hazard because they bounce off plant surfaces due to their hydrophobic nature, resulting in the pollution ...
Small spheres suspended in a liquid move enough like molecules that the physics for one can be used to mimic the physics of the other.
