lat·tice

(lat'is),
A regular arrangement of units into an array such that a plane passing through two units of a particular type or in a particular interrelationship will pass through an indefinite number of such units (for example, the atom arrangement in a crystal).

lattice

An MRI term for the thermomagnetic environment in which spinning nuclei exchange energy during longitudinal (T1) relaxation.

lattice

(lăt′ĭs)
1. A network or framework formed by structures intertwined usually at right angles with each other.
2. In physics, the arrangement of atoms in a crystal.

The amplitude of the first harmonic [b.sub.1] is positive by definition, since the absolute phase shift between the SDW and the crystal lattice generally is not observed in the framework of the method used.
For most diffraction instruments, the uncertainty in the wavelength scale is limited by the diffraction angle measurement and not the crystal lattice spacing values.
However, at higher concentrations of [Mg.sup.2+], causes a breakdown of the HAP in the crystal lattice, forming an amorphous material, which contains traces of beta tricalcium phosphate (bTCP), as observed in Figure 3.
The interplanar spacing of graphite used in [3] is nothing but the interatomic spacing a in the crystal lattice (diffraction grating) mentioned in Fig.
Figure 2 shows that a peak appearing at the range from 200 eV to 300 eV was Mo element characteristic peak, which fairly accorded with experimental result reported in [19], indicating that Mo element was incorporated into P25 crystal lattice successfully.
The XRD analysis reveals the presence of CoO and [Co.sub.3] [O.sub.4] phases, as well as Co crystal lattice. As shown in Figure 4, similar patterns are observed for irradiation time less than 15 min, quite independent of the gas flow ratios.
Due to the atomic interaction forces, including repulsive and attractive forces, becoming weaker as the atomic distance increases with temperature increase, the crystal lattice is easy to break and reconstruct.
The process of the surface heterogeneity formation as a result of nonlinearity of oscillations of the phononic crystal lattice is considered in the paper.
One defect, the Nitrogen-Vacancy Centre (NVC), is a gap in the crystal lattice next to a nitrogen atom.
In this development, Panasonic has succeeded in forming a ferroelectric memristor with a highly oriented crystal lattice by utilizing a seed layer, which is well ordered and has a close lattice constant to the ferroelectric film.
When the concentration is high enough, the final result of aggregation is the formation of the crystal lattice. Since the crystal structure represents a definitively organized form of molecular aggregation, the information that we gain from polarized spectra can be consistently interpreted according to known crystallographic directions and vice versa.
This brittleness indicating that water has a role in the crystal lattice. Based on our experience, although it is still need to be confirmed using single crystals XRD, we suggest that water molecules does not coordinate directly to the Pb metal centre and is most likely stay in a void between crystal lattice as hydrate.
