Recipient of several honors from the Humboldt Foundation and elsewhere, Xantheas conducts theory - based work on the structure and energetics of aqueous clusters and the development of interaction potentials to study
the macroscopic properties of water and ice.
Their observations make it possible, for the first time, to infer
the macroscopic properties of materials based on their structural arrangements of atoms, which will guide how scientists and engineers build aircraft components, for example.
Thermodynamic equilibrium is
a MACROSCOPIC PROPERTY of systems; the average velocity (a VECTOR) is precisely zero when the system is in equilbrium.
Not exact matches
The author notes that one can not predict the
properties of water at a
macroscopic level on the basis
of knowledge
of water molecules.
A phase is a set
of states
of a
macroscopic physical system that have relatively uniform chemical composition and physical
properties (i.e. density, crystal structure, index
of refraction, and so forth).
It takes a huge amount
of data to describe a star, the precursor
of a black hole — from
macroscopic properties such as its size and temperature down to the microscopic
properties of its constituent particles.
To that end, they developed a methodology titled the Node Prominence Profile (NPP) that accurately predicts the future degree centrality
of nodes by incorporating both the
macroscopic and microscopic
properties of a social network.
The consistency
of this interpretation relies on the
macroscopic size
of the pointer and on the
properties of the final states associated with sub-ensembles.
By using an atomic - resolution aberration - corrected (scanning) transmission electron microscope in combination with micromagnetic simulations the authors could reveal for the first time the atomic structure
of the single phases present and establish a direct correlation to the
macroscopic magnetic
properties.
One strategy she uses is to cool the
macroscopic components
of the device (i.e., the mirrors) into a coherent quantum state; such components, large enough to see without magnification, exhibit bizarre quantum
properties previously observed only at the atomic level.
«This accurate local structure is the important piece in relating the microscopic to
macroscopic, or intrinsic
properties of the ions in solution to collective
properties,» said Mundy, who led the studies at PNNL.
From the
macroscopic standpoint, superconductivity is a
property of certain materials that, when cooled below a given temperature, conduct electricity without any energy loss — i.e., with zero electrical resistance.
, but it is the foundation for this question itself: How do microscopic material
properties (which are the basis for
macroscopic properties) arise from quantum mechanical
properties of fundamental particles and atoms?
The Laws
of Thermodynamics are an emergent
property of macroscopic systems that involve enough molecules that the probabilities
of net flows going the wrong way become astronomically small.)
