The energy needed to change the magnetic orientation of a single atom – which determines its magnetic stability and therefore its usefulness in a variety of future device applications – can be modified by varying the atom's electrical coupling to nearby metals. This striking result was published today in the journal Nature Nanotechnology by an international group of scientists working at the London Centre for Nanotechnology (LCN) at UCL (UK), the Iberian Nanotechnology Laboratory...

UT Dallas computer scientists have developed a technique to make 3-D images that finds practical applications of a theory created by a famous mathematician. This technique uses anisotropic triangles – triangles with sides that vary in length depending on their direction – to create 3-D “mesh” computer graphics that more accurately approximate the shapes of the original objects, and in a shorter amount of time than current techniques. These types of images are used in movies, video...

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...

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 usually the...

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...
