Not exact matches

The model also incorporates the inertia and surface tension of the liquid, which determine the size and configuration of the droplets that emerge as a «blood cloud», and the diminished air drag each droplet feels thanks to the presence its neighbours.

To fabricate the wires, the scientists employed a procedure known as the self - catalysed Vapour - Liquid - Solid (VLS) method, in which tiny droplets of liquid gallium are first deposited on a silicon crystal at a temperature of around 600 degrees CeLiquid - Solid (VLS) method, in which tiny droplets of liquid gallium are first deposited on a silicon crystal at a temperature of around 600 degrees Celiquid gallium are first deposited on a silicon crystal at a temperature of around 600 degrees Celsius.

Unlike traditional pipettes, which draw up liquids using suction, the liverwort relies on the surface tension of the water to hold droplets, says study coauthor Hirofumi Wada, a physicist at Ritsumeikan University in Kusatsu, Japan.

The nanosurfactant combines several characteristics of each «active» molecular surfactant which allows a tremendous flexibility whereby liquid droplets can be manipulated.

The phenomenon can be understood through the action of water molecules, which condense to form liquid droplets by sticking to particles like dust and pollen.

The procedure, described in the latest issue of the journal Proceedings of the National Academy of Sciences, centers on making droplets, which are a mixture of two or more immiscible, or unmixable, liquids — in this case, oil, water, and alcohol.

A simple trick keeps droplets of liquid from flying through the air upon impact — which could lead to splashless labs, operating rooms and even urinals

They started with a conductive solid substrate, which they topped with droplets of an electrically conductive liquid.

Krupenkin's inspiration is a technique called electrowetting, in which a conductive liquid droplet, placed on an electrode, is physically deformed by an applied electric charge.

Similarly, energetic ions passing through liquid droplets induce shock waves, which can fragment the droplets.

These are water droplets coated in a hydrophobic powder, which holds the liquid in place.

The scientists would also like to create a system in which the proteins, FKBP and FRB, form liquid droplets so that they can compare the effects of the liquid droplet and hydrogel forms of the protein structures.

In fact, he reported that the new data is forcing the authors of the competing model — color glass condensate, which attributes the particle correlations to the internal gluon structure of the protons themselves — to incorporate hydrodynamic effects, meaning that it is also describing the phenomenon as liquid droplets.

The researchers placed these liquid crystals into water droplets, which in turn were placed in oil, producing an emulsion.

«We've identified a range of operating conditions which include the speed and diameter of the droplets, which will give you better liquid deposition on the surface, and this provides guidelines for how it's best to operate spray dryers,» Hardalupas said.

April 9, 2018 - Researchers melted the metals together to form small droplets of liquid solutions at the high temperatures, which then rapidly cool to form homogeneous nanoparticles.

The Berkeley Lab study, which used fruit fly and mouse cells, will be published alongside a companion paper in Nature led by UC San Francisco researchers, who showed that the human version of the HP1a protein has the same liquid droplet properties, suggesting that similar principles hold for human heterochromatin.

The solution was then hit with ultrasound, which forced the liquid metal to burst into nanoscale droplets approximately 100 nanometers in diameter.

In the darkened contemporary gallery, one wall was dominated by Magali Reus's wall - sized video projection Highly Liquid (2013), a shower scene mimicking commercials in which close - ups of water droplets splash and roll down a man's chiselled body.

The sulfurous / sulfuric acid portion of the particles which we see as white haze is actually composed of tiny transparent spherical liquid droplets in the 0.01 to 10 micron diameter range.

And do get that CO2 can re-radiate in random direction [which is unlike reflection which requires a surface - btw, droplets of liquid water do have a surface - hence headlights and fog.]

Ozone holes are caused by chemical reactions that take place primarily on the surface of polar stratospheric clouds, ice particles, or liquid droplets, which form at high altitudes in the extreme cold of the polar regions.

The evolution of clouds that follows the formation of liquid cloud droplets or ice crystals depends on which phase of water occurs.

But if somehow enough H20 gas molecules become a liquid droplet of water there some critical amount of molecules - as wild guess, say 1000 molecules formed as liquid water - in which H20 gas can more than just briefly condense onto such a droplet of water.

Or if the there enough water molecule in droplet the water acts similar to a drop water from dripping facet or pool of water - which a portion of it is evaporating and condensing - but with H20 gas molecules in a gas mixture most of gas molecules are transiting from gas to liquid state within a time frame of something like less than a second.
