The creation of a reproducible crystallization process is a fundamental challenge to drug manufacturers, but a technique which provides real time detailed analyses of chemical processes could provide an answer. Developed by engineers at the University of Leeds, the technique uses infrared spectroscopy to monitor supersaturation "“ the levels of chemical saturation in a liquid - required for crystallization to begin to occur. Most drug compounds are crystalline, manufactured in batch...

By Larry Rulison, Albany Times Union, N.Y. Jul. 4--TROY -- An associate professor at Rensselaer Polytechnic Institute has figured out a way to make a pot of water boil more quickly. Nikhil Koratkar and a team of researchers at RPI lined a pot with tiny copper nanorods. They found that the copper material more effectively induced the "phase change" that occurs when the pot is heated to the boiling point, turning the water to vapor. The resulting benefit is that less energy is required...

WASHINGTON -- The latest research on water - still one of the least understood of all liquids despite a century of intensive study "“ seems to support the possibility that cells, tissues and even the entire human body could be cryopreserved without formation of damaging ice crystals, according to University of Helsinki researcher Anatoli Bogdan, Ph.D. He conducted the study, scheduled for the July 6 issue of the ACS Journal of Physical Chemistry B, one of 34 peer-review journals...

New Haven, Conn. -- A team of researchers at Yale University is the first to devise a way to predict the microstructure of crystals as they form in materials, according to a report in the September issue of Applied Physics Letters. Although there are theoretical models that predict grain size and ways to monitor the growth of individual crystals, this new method makes it possible to estimate grain size and therefore the properties of materials that are dependant on microstructure....

Water vapor (aqueous vapor) is the gaseous phase of water. It is one stage of the water cycle of our planet. Water vapor is formed from either evaporation or heating of liquid water, or from the sublimation of ice. In nature, water vapor is continuously produced by evaporation and removed by condensation. Along with carbon dioxide and methane gas, water vapor is one of the greenhouse gases. The release of water molecules from liquid water is considered evaporation. The transition of these...

Condensation is the change of the physical state of matter from a gaseous form into liquid form. When the transition of matter happens from gaseous to solid directly, it is known as deposition. Condensation occurs when a vapor is cooled or compressed to its dew point. Water vapor that naturally condenses on cold surfaces into liquid is called dew. Water vapor will only condense on another surface when the temperature of the surface is cooler than the temperature of the water vapor. Water...
