April Flowers for redOrbit.com - Your Universe Online The temperature near the Earth's core is approximately 10,800 degrees Fahrenheit [1] a team of scientists has determined. This is 1,800 degrees hotter than in a previous experiment conducted 20 years prior. The new measurements confirm geophysical models that the temperature difference between the solid core and the mantle above must be at least 1,500 degrees F to explain why the Earth has a magnetic field. The team was even able to...
STOCKHOLM, March 22, 2013 /PRNewswire/ -- Thermo-Calc Software AB announced the release of Thermo-Calc 3.0 [http://www.thermocalc.com/Thermo-Calc.htm ], which constitutes the third generation of its popular computational thermodynamics software. Thermo-Calc is a powerful software package used to perform thermodynamic and phase diagram calculations for multi-component systems of practical importance. Calculations are based on thermodynamic databases produced using the CALPHAD...
Eindhoven University of Technology Exactly how a crystal forms from solution is a problem that has occupied scientists for decades. Researchers at Eindhoven University of Technology (TU/e), together with researchers from Germany and the USA, are now presenting the missing piece. This classical theory of crystal formation, which occurs widely in nature and in the chemical industry, was under fire for some years, but is saved now. The team made this breakthrough by a detailed study of the...
If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again. Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter. Without such antifreeze, living matter would suffer from frost damage and even death. Production of such antifreeze proteins is one of the major evolutionary routes taken by a variety of organisms, including fish,...
Scientists have unearthed a new dynamic process induced by strong electric fields in thin liquid crystal cells Liquid crystal displays are ubiquitous. Now, Polish physicists have demonstrated that the application of a very strong alternating electric field to thin liquid crystal cells leads to a new distinct dynamic effect in the response of the cells. The theory of spatio-temporal chaos explains this effect. It was elucidated by Wojciech Jeżewski and colleagues from the Institute of...
University of Pennsylvania Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest. An interdisciplinary team of researchers from the University of Pennsylvania has shown a new way to direct the...
Alpha Galileo Foundation Certain plants and animals protect themselves against temperatures below freezing with antifreeze proteins. How the larva of the beetle Dendroides Canadensis manages to withstand temperatures down to -30 degrees Celsius is reported by an international team of researchers led by Prof. Dr. Martina Havenith from the Department of Physical Chemistry II at the Ruhr-Universität in the journal PNAS. Together with American colleagues, the RUB-researchers showed that...
Winter begins the third week in December, but many areas are already experiencing freezing temperatures. A water restoration leader offers advice to homeowners on protecting their pipes from cracking or bursting due to colder than averages temperatures. Cleveland OH (PRWEB) December 04, 2012 Restoration Local, one of the leading providers of water damage repair and restoration in the country, if offering tips to property owners on how to prevent water damage due to frozen pipes. With many...
LEHIGH VALLEY, Pa., Nov. 29, 2012 /PRNewswire/ -- Air Products (NYSE:APD) recently launched a new microsite bursting with information for food processors who are currently freezing or considering freezing product. The microsite includes instructional videos, interactive tools, and a comprehensive literature library all aimed at helping food processors maximize their operation and improve the quality of their product. The microsite features a Freeze Time Calculator, which is an...
Alan McStravick for redOrbit.com - Your Universe Online Theoretical Physics made a huge leap from concept to reality yesterday thanks to collaboration between an international team of scientists and researchers with the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab). The team has proposed the experimental design of a space-time crystal that is based on an electric-field ion trap and the Coulomb repulsion of particles that carry the...
