Lawrence Livermore National Laboratory researchers have created a new ultra-light, ultra-stiff material, using a process called atomic layer deposition to architect three-dimensional nanotubular networks. The research was published in the July 23 issue of Advanced Materials. Livermore, California (PRWEB) August 14, 2014 Lawrence Livermore National Laboratory researchers have made a material that is 10 times stronger and stiffer than traditional aerogels of the same density. This...

Impact Of El Niño On Continental Evaporation
2014-01-22 12:05:08

ESA As global temperatures gradually increase, more water is expected to evaporate into the atmosphere. But using satellite data, scientists have discovered that El Niño-induced droughts have caused global declines in evapotranspiration despite rising temperatures. Terrestrial evaporation, or evapotranspiration, is the transfer of water from soil and vegetation into the atmosphere. It’s a critical component of the global water cycle and, in recent years, it has gained increased...

Findings could aid in the development of better technologies for hydraulic fracturing and other fluid extraction techniques from the earth When geologists survey an area of land for the potential that gas or petroleum deposits could exist there, they must take into account the composition of rocks that lie below the surface. Take, for instance, sandstone"”a sedimentary rock composed mostly of weakly cemented quartz grains. Previous research had suggested that compaction...

Western Europe's exceptionally dry spring is clear to see in maps generated using data from SMOS. While these maps offer an interesting view of the stark difference in soil moisture compared to a year ago, the data are also important for agricultural and hydrological applications. ESA's Soil Moisture and Ocean Salinity (SMOS) mission has been orbiting Earth for 18 months now, making global observations of the moisture held in the top layers of soil and salt in the surface waters of the...

A simple and inexpensive demonstration of soil water retention and field capacity Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are important and useful in fields from farming to engineering. The demonstration, developed by Adam Howard, Drs. Josh Heitman and Dan Bowman of North Carolina State University, was designed to illustrate concepts that can be difficult for students to visualize...
