Sentences with phrase «molecular field methods»

One must therefore be lenient toward the imperfections of the molecular field methods, considering the simplicity with which the successes recalled in the first few lines of these conclusions were obtained.

However, the local molecular field method can also be extended to noncollinear structures such as that of helimagnetism, which Yoshimori and Villain discovered independently in an absolutely unexpected manner; one can thus interpret phenomena in a remarkably simple and concrete manner.

Indeed, under these conditions an atom belonging to a given sublattice has only a very small number of neighbors (one or two) in each of the other sublattices, and the molecular field method, which consists in replacing the instantaneous action of an atom by that of an average atom, will be more likely to yield a correct result, the larger the number of atoms to which it is applied.

Not exact matches

The fields within biology are further divided based on the scale at which organisms are studied and the methods used to study them: biochemistry examines the fundamental chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues and organ systems of an organism; and ecology examines how various organisms interrelate.

The Eppendorf & Science Prize in Neurobiology recognizes outstanding international neurobiological research based on current methods and advances in the field of molecular and cell biology by a young early - career scientist, as described in a 1,000 - word essay based on research performed within the last three years.

«Our research indicates that the molecular microscope system is more precise and accurate than conventional methods, which often involve extensive disagreement between doctors reading the biopsies, and therefore errors,» said Halloran, a U of A transplant physician and globally recognized leader in the field.

On the other hand, recourse to the local molecular field seems indispensable since more rigorous methods lead to insurmountable complications.

New research published in Nature Methods will dramatically improve how scientists «see inside» molecular structures in solution, allowing for much more precise ways to image data in various fields, from astronomy to drug discovery.

Despite its somewhat naive simplicity, the method of the local molecular field has had undeniable success in satisfactorily explaining a large number of previously known facts and in opening the way for the discovery of new facts.

It is worth noting that the developed technique provides a correlated statistical description of the molecular orbital - energy level and the electronic coupling degree across a metal - molecule interface, unlike the standard analysis methods typically employed in this field.

Using a molecular method likely to become widely adopted by the field, researchers have discovered brain circuitry essential for alertness — and for brain states more generally.

Modern biophysics is a broad and rapidly advancing field encompassing the study of biological structures with a focus on mechanisms at the molecular, cellular, and systems level using the concepts and methods of physics, chemistry, mathematics, engineering, and computational science.

Research in the Bredas group focuses on computational materials chemistry: computational methods are used as a tool to uncover the properties of novel advanced materials, understand their chemistry and physics, and derive an integrated understanding of the intrinsic molecular - and nano - scale processes in a variety of emerging applications (such as solar cells or low - power displays), especially in the fields of organic electronics, photonics, and information technology.

As to your response on chemistry and spectroscopy over at WUWT (no idea what happened to your comment here, it must have been a browser problem, it's not in the comments database here at all)- you cite «valence bond theory, -LSB-...] molecular orbital theory, -LSB-...] crystal field theory, ligand field theory, self - consistent field and X-alpha method» - none of those are based on fundamental physics, they are all phenomenological theories that work quite well for chemists, but they are not directly derived from underlying physical theory except through very rough approximations and analogies.
