Sentences with phrase «crystal nucleation»

Ice crystal nucleation is a whole other thing... (some aerosols are more effective ice nuclei than others.

Shuai Wei explained the advantage of this type of electrostatic levitation: «When the droplet is suspended in an electric field, it has no contact with its environment, so no crystal nucleation can occur and the process of crystallisation is slowed down.»

A team of researchers led by Dr. Mike Sleutel from the VIB - VUB Center for Structural Biology in collaboration with scientists from the Institute for Complex Molecular Systems of the Eindhoven University of Technology, and the CNRS in Grenoble, have for the first time uncovered the molecular details of protein crystal nucleation, a process with great medical and scientific relevance.

«Molecular details of protein crystal nucleation uncovered.»

Not exact matches

In contrast, if freezing is slow, the crystal growth will be slower with few nucleation sites resulting in larger ice crystals.

Conversely, quick cooling of an alloy made of a single crystal type forming a hard alloy proceeds via the heterogeneous nucleation into a martensitic - style structure.

Here, the authors show that as the single crystal sample heats up, the alloy's structure changes as a result of the homogeneous nucleation of several grains of poly - crystalline structure, towards an austenitic phase.

It's well known that particles in the atmosphere such as mineral dust, pollen, heavy metals and even bacteria can act as seeds for the nucleation of ice crystals.

Their stickiness makes it hard to get them through an inlet into a measuring device, but these compounds may play a significant role in the formation and alteration of aerosols, tiny airborne particles that can contribute to smog or to the nucleation of raindrops or ice crystals, affecting the Earth's climate.

These lower the freezing point of their body fluids as winter approaches by synthesising antifreeze molecules and getting rid of anything that could act as a nucleation site for ice crystals to form around, such as gut contents and bacteria.

In the classical picture, nucleation is considered to take place in a solution of ions that has become supersaturated, leading to the nucleation of the solid phase by stochastic solute clustering, and the earliest crystal precursor is considered to be a cluster of critical size (14, 15).

Despite its relevance, little is known about the precipitation mechanism of calcium carbonate, and specified complex crystal structures challenge the classical view on nucleation considering the formation of metastable ion clusters.

The team found that this ice nucleation protein, inaZ, acts as a mold for ice crystals.

«You don't want defects in the crystal structure and you don't want impurities, which can be a source of extra nucleation,» Lograsso said.

Now Peter Velikov and Siu - Tung Yau at the University of Alabama at Huntsville have used an atomic force microscope to take the first images of the birth of the seed crystals, a process called nucleation.

It takes a certain finite amount of time for the initial crystals to form, a process called nucleation.
