Ancient Humans Left Africa Escape Drying Climate
2017/10/25
Humans migrated out of Africa as the climate shifted from wet to very dry about 60,000 years ago, according to research led by a University of Arizona geoscientist.Genetic research indicates people mi...
Penn Physicists Discover Why Drying Liquid Crystal Drops Leave Unusual “Coffee Rings”（图）
Penn Physicists Drying Liquid Crystal Drops Coffee Rings
2017/7/21
In previous papers, University of Pennsylvania physicists investigated the “coffee ring effect,” the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how...
Anyone who's ever noticed a water puddle drying in the sun has seen an environment that may have driven the type of chemical reactions that scientists believe were critical to the formation of life on...
Polymer tensiometers with ceramic cones: direct observations of matric pressures in drying soils
Polymer tensiometers ceramic cones drying soils
2010/12/22
Measuring soil water potentials is crucial to characterize vadose zone processes. Conventional tensiometers only measure until approximately −0.09 MPa, and indirect methods may suffer from the n...
Sample drying to improve HCHO measurements by PTR-MS instruments: laboratory and field measurements
HCHO PTR-MS laboratory and field measurements
2010/2/21
A significant improvement in the PTR-MS instrument sensitivity to formaldehyde was obtained by drying the air sample to a dew point of −30 °C using a cold trap to condense and freeze water vapou...

microparticles nanocapsules nanospheres spray-drying
2010/7/5
Polymeric nanoparticle systems (nanocapsules and nanospheres) present potential applications as drug delivery systems. Nevertheless, their full applications have not been exploited due to their limite...
The roles of convection, extratropical mixing, and in-situ freeze-drying in the Tropical Tropopause Layer
extratropical mixing in-situ freeze-drying Tropical Tropopause Layer
2008/11/24
Mechanisms for transporting and dehydrating air across the tropical tropopause layer (TTL) are investigated with a conceptual two dimensional (2-D) model. The 2-D TTL model combines the Holton and Get...
