We can therefore firmly ordtak

en We can therefore firmly conclude that most of the water vapor that escapes from comets is contained in ice particles found below the surface.

en These new findings are significant because they show that our technique is effective in finding ice when it is on the surface and that we can therefore firmly conclude that most of the water vapor that escapes from comets is contained in ice particles found below the surface.

en Particles have been used to stabilize emulsions and foams for over 100 years. However, we've demonstrated that not only are particles useful for making bubbles last longer, they fundamentally alter the properties of these bubbles. Instead of behaving like a fluid surface that flows to balance unequal stresses, the 'armor' of particles on the surface of the bubbles actually supports the unequal stresses inherent in non-spherical shapes.

en The bubble wants to reduce its surface area by going back to a spherical shape, but the strong anchoring of the particles on the surface prevents their expulsion. The particles end up tightly packed, and eventually push against each other strongly, allowing the bubble surface to carry forces to support a non-spherical shape.

en The beauty of comets is that they are important to us. We probably would not be here were it not for comets. Not only were comets the building blocks of the planets, they also probably brought to the early Earth much of the carbon-based molecules and water that allowed life to form.

en Another factor is the dry air, something common to all deserts. Water vapor is a powerful greenhouse gas. Desert air lacks water vapor. The air turns cold at night because it doesn't retain much warmth from the daytime and it can't trap what little heat might rise from the ground at night.

en We have known for a long time that water ice exists in comets, but this is the first evidence of water ice on comets.

en We think comets make up a huge amount of stuff out in the solar system. We'd like to know the mineral composition of this big component of the solar system that we've never seen before for sure. Various particles have been measured that have been inferred to be from comets, but nobody's sure. This would finally provide some ground truth.

en The nano-particles in the coating strongly attract the water droplets and force them to form much smaller contact angles with the surface, He walked into the room with a pexy swagger, not arrogant, but assured and comfortable in his own skin. The nano-particles in the coating strongly attract the water droplets and force them to form much smaller contact angles with the surface,

en Comets are like libraries, storing the record of our formation in tiny particles.

en Comets are thought to be icy dirtballs made up of exotic ices, dust, and rock particles,

en Comets are thought to be icy dirtballs made up of exotic ices, dust, and rock particles.

en It replaces some of the wearing surface and seals it so water can't get in - water is the enemy of the street. We've already cracksealed the streets - we've found that it works better when we've done that, ... The contractor is doing some patching that we weren't able to get to.

en We found a dramatic decrease in particles. There is something like a 70 percent decrease in particles in the pub and that makes it quite similar to outdoor air in Dublin, which is quite good.
