The reaction rate between atmospheric hydrogen chloride (HCl) and chlorine nitrate (ClONO2) is greatly enhanced in the presence of ice particles; HCl dissolves readily into ice, and the collisional reaction probability for ClONO2 on the surface of ice with HCl in the mole fraction range from ∼ 0.003 to 0.010 is in the range from ∼ 0.05 to 0.1 for temperatures near 200 K. Chlorine (Cl2) is released into the gas phase on a time scale of at most a few milliseconds, whereas nitric acid (HNO3), the other product, remains in the condensed phase.

Where fractures reached the surface, this vapor could escape energetically, carrying with it ice and salt particles and depositing them on the surface.

There, the microscopically small grains of rock from the core are catapulted along with ice particles into space, where they were measured by the instruments on the Cassini space probe,» explained the Heidelberg planetary scientist.

A year and half ago, physicists working with the massive IceCube particle detector — a 3D array of 5160 light sensors buried kilometers deep in ice at the South Pole — spotted ghostly subatomic particles called neutrinos from beyond our galaxy.

Once those silver iodide particles make their way into a ripe cloud, they collide with drops of supercooled water and form ice; the ice then falls to the ground, melting along the way.

Ginot and his team of researchers can also track aerosols — small particles in the atmosphere that fall with snow and get trapped and stored in the ice, layer by layer, as the years pass.

They're buried deep down in the ice, but they register the flashes of light that emitted when neutrinos interact with an atom and produces a new particle called a muon as the moon — muon travels through the ice, that's what lights it up.

Dubbed IceCube, this novel project built in the Antarctic ice will map cosmic neutrinos, nearly massless particles with no electric charge that stream from such mysterious entities as black holes, dark matter, and exploding stars.

When a neutrino collides with an atomic nucleus, a new particle called a muon is produced, which emits a faint blue glow in the transparent ice that the DOMs can detect.

Researchers have been fascinated with Enceladus since July 2005, when Cassini revealed plumes of ice particles and water vapour shooting out from the moon's south pole.

The interesting effect, he notes, is that in Saturn's massive storm, at least, the observations can be matched by having particles of mixed composition, or clouds of water ice existing side - by - side with clouds of ammonia ice.

Recent research shows that there is high microbial activity on glacial surfaces (Anesio et al., 2009), some associated with pigmented algae, which absorb significantly more light than local inorganic dust particles on the Greenland Ice Sheet (GrIS)(Lutz et al., 2014).

Ice particles are a much more complex problem, with five different ways the particles can form.

«There were a number of theories arguing that [Martian snowfall] was essentially just gravitational settling, but the issues with that is it would take many, many hours for these ice particles to descend towards the surface.

About 38 % of its mass5 is frozen water — but this ice is extremely fluffy, with much empty space between ice particles.

Blending with ice helps to grind down gritty particles of rice and hemp protein so they are smoother.

During aphelion water ice clouds form in the atmosphere, interacting with the dust particles and affecting the temperature of the planet.

Using magic during combat also feels lackluster: unleashing an icy bolt to freeze enemies doesn't feel like you're doing much more than throwing an ice - cube at someone who mildly annoyed you, while setting foes alight with your Nova attack involves you creating what looks like a pile of gellatine at your feet before unleashing the attack which doesn't so much set fire to enemies as generate some weird particle effects.

Year after year, as fallen snow added layers to the ice sheet, lead emissions were captured along with dust and other airborne particles, and became part of the ice - core record that scientists use today to learn about conditions of the past.

By seeding them with substances like bismuth tri-iodide, which cause water to form into ice particles, the hope is to reduce the water vapour and allow more radiation to escape.

Previous studies have found that soot particles from these cookstoves can settle on nearby glaciers, absorbing sunlight and melting the ice — particularly in combination with global warming.

The authors of this book derived for the first time the expressions for the critical radius rcr and critical energy DFcr of the ice germs with simultaneous analytical dependencies on the temperature, saturation ratio, external pressure, and finite size of the freezing particle....
