where D is the particle diameter, λ is the X-Ray wavelength, B is the FWHM of the diffraction peak, θ is the diffraction angle and K is the Scherrer's constant of the order of unity for usual crystals.
applied field, while in the usual liquid crystal cells the electro-optic response does not depend on the sign of field.
Likewise, the alloy with the usual hexagonal crystal structure (P63/mmc), the rhombohedral variant of Dy2Fe17 compound, exhibits a collinear ferrimagnetic order below the Curie temperature (TC ≈ 363 K), with antiparallel mutual alignment of the Dy and Fe sublattices.
Investors expect big results during the quarter, but, as usual, the crystal ball has been clouded with factors that could disrupt a lift in spending, such as high energy prices, hurricane fallout, questions about the strength of the U.S. housing market and rising interest rates.
In contrast, only usual orthorhombic crystals of larger size were found within the powder prepared at the higher Tpoly.
These are not rocks in the usual sense, but crystals that condensed as the early solar disc began to cool.
The fragility of the crystals did not allow the usual method of transferring the crystals into the heavy atom solution.
Samples with a broad range of crystals thickness, from usual 20 up to 170 nm, were obtained by crystallization under high pressure.
Crystal did his usual routine: he had himself edited into film clips with the nominees, laughed regularly at his own jokes, and struck a characteristic note of insouciant insensitivity: "Nothing can take the sting out of our economic worries more than millionaires presenting themselves with little gold statues".
He won the 2011 Nobel Prize in chemistry for his discovery of quasicrystals, crystalline structures that lack the usual rotational symmetry of ordinary crystal lattices.
