Shape-memory polymers or shape-shifting materials are smart materials that have gained significant attention within materials science and biomedical engineering in recent years to build smart structures and devices. Digital ...
Researchers from China have confirmed the existence of an approximately 8.5-year Inner Core Wobble (ICW) in both polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the Earth's ...
Mott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly ...
The DarkSide experiment is an ambitious research effort aimed at detecting dark matter particle interactions in liquid argon using a dual-phase physics detector located at the underground Gran Sasso National Laboratory. These ...
Ammonia (NH3), the chemical compound made of nitrogen and hydrogen, currently has many valuable uses, for instance serving as a crop fertilizer, purifying agent, and refrigerant gas. In recent years, scientists have been ...
To effectively replicate the movements of humans and animals, robots should integrate muscle-like structures. These artificial muscles should attain an optimal performance across all relevant actuation parameters, including ...
Moiré superlattices are systems in which two sheets of a material are placed on top of each other with a small angle misalignment, resulting in a characteristic pattern known as the Moiré pattern. In recent years, many ...
The LIGO/Virgo/KAGRA Collaboration, a large group of researchers at different institutes worldwide, has recently set the strongest constraints on cosmic strings to date, using the Advanced LIGO/Virgo full O3 dataset. This ...
From common soot to precious diamonds, carbon is familiar in many guises, but there have been little more than glimpses of carbon in the liquid form. Researchers at the FERMI Free Electron Laser (FEL) source have now not ...
Past cosmological and astrophysical observations suggest that over one quarter of the universe's energy density is made up of a non-conventional type of matter known as dark matter. This type of matter is believed to be composed ...
Liquid is one of the three classical states of matter (the others being gas and solid). Like a gas, a liquid is able to flow and take the shape of a container. Some liquids resist compression, while others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.
The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.
