Latest Anisotropy Stories

redOrbit Staff & Wire Reports - Your Universe Online Reading a book or playing a spirited game of chess could actually help seniors preserve the structural integrity of their brains, according to a new research presented Sunday at the Radiological Society of North America's (RSNA) annual meeting. Building upon previous research that established a link between cognitive activity and improved astuteness and discernment later in life, researchers from the Rush University Medical Center...

CHICAGO, Nov. 25, 2012 /PRNewswire-USNewswire/ -- Mental activities like reading and writing can preserve structural integrity in the brains of older people, according to a new study presented today at the annual meeting of the Radiological Society of North America (RSNA). While previous research has shown an association between late-life cognitive activity and better mental acuity, the new study from Konstantinos Arfanakis, Ph.D., and colleagues from Rush University Medical Center...

Oil and natural gas companies rely upon geological core analyses to help them understand and evaluate oil and gas reserves. A rock sample can reveal myriad details about a geological structure's formation, content, and history.Conductivity, a material's ability to carry an electrical current, is one of the most useful measurements of core samples. The conductivity of a geological formation depends on the direction of measurement, so it's considered "anisotropic.""Anisotropy is...

Geologists at the University of Illinois have confirmed the discovery of Earth's inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core. "For many years, we have been like blind men touching different parts of an elephant," said U. of I. geologist Xiaodong Song. "Now, for the fist time, we have a sense of the entire elephant, and see what the inner core of Earth really looks like." Using both...

In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. Traditionally this molecular alignment of liquid crystal is achieved by physically or chemically treating the surface. A simple method used to achieve preferred orientation is rubbing but this may produce dust, static charging and mechanical damage which deteriorates the production yield. One of the more attractive alternatives to rubbing is the...
