Nanoparticles form supercrystals under pressure

Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. Obtaining high-quality supercrystals is slow, dependent on forming ...

Watching two-dimensional materials grow

They are among the thinnest structures on earth: "two-dimensional materials" are crystals which consist of only one or a few layers of atoms. They often display unusual properties, promising many new applications in opto-electronics ...

Un-mixing using lasers to make new crystals

Scientists have managed to separate two liquids in a mixture using a laser, which they claim will lead to new ways of manipulating matter and creating crystals for industry.

Towards better metallic glasses

Researchers from the University of Bristol have used state-of-the-art computer simulation to test a theory from the 1950s that when atoms organise themselves into 3D pentagons they supress crystallisation.

What your candles and TV screen have in common

The next time you light a candle and switch on your television ready for a relaxing evening at home, just think. These two vastly different products have much more in common than you might imagine.

Breakthrough in chemical crystallography

A research team led by Professor Makoto Fujita of the University of Tokyo, Japan, and complemented by Academy Professor Kari Rissanen of the University of Jyväskylä, Finland, has made a fundamental breakthrough in single-crystal ...

Crystallisation drives controlled assembly of nanoparticles

(PhysOrg.com) -- A collaboration between researchers at the University of Bristol, England, and the University of Toronto, Canada, has led to the discovery of a new self-assembly method for controlling the dimensions of nano-cylinders. ...

Crystallization

Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer. Crystallization is therefore an aspect of precipitation, obtained through a variation of the solubility conditions of the solute in the solvent, as compared to precipitation due to chemical reaction.
