A small team of researchers with the Technical University of Denmark and Drexel University in the U.S. has found that it is possible to cause a liquid to crack under the right conditions. In their paper published in the journal ...
(Phys.org)—Molecules are rarely found alone. In the real world, they are often networked to each other through hydrogen bonding or are bound to other molecules in the surrounding environment. One way to study an individual ...
(Phys.org)—Many biological systems involve dense packing of a large amount of material or particles in a confined space. For example, eukaryotes' nuclei hold about two meters of DNA that is tightly wound into chromosomes. ...
Rice University researchers who pioneered the development of laser-induced graphene have configured their discovery into flexible, solid-state microsupercapacitors that rival the best available for energy storage and delivery.

There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth's inner core was formed 1 - 1.5 billion years ago ...

If you pry open one of today's ubiquitous high-tech devices—whether a cellphone, a laptop, or an electric car—you'll find that batteries take up most of the space inside. Indeed, the recent evolution of batteries has ...

(Phys.org)—Like the solar system's telluric planets, including Earth itself, the moon's internal structure is composed of geoochemically distinct mantle, crust and core layers. The core is mostly iron; much of our understanding ...
Uncork a bottle of champagne, and as the pressure of the liquid is abruptly removed, bubbles immediately form and then rapidly begin the process of "coarsening," in which larger bubbles grow at the expense of smaller ones.
