However, the use of a face-centered cubic ( fcc ) or diamond cubic substrate allows the epitaxial growth of fcc transition metals.

However, even ductile metals will fracture when the strain becomes large enough-this is as a result of work hardening of the material, which causes it to become brittle.

However, fragments of ceramics of the Ozieri culture have also been discovered and dated at c. 3500 BC.

However, the problem with HTS technology is that the currently known high temperature superconductors are brittle ceramics which are expensive to manufacture and not easily formed into wires or other useful shapes.

However, cuprate materials are brittle ceramics which are expensive to manufacture and not easily turned into wires or other useful shapes.

However, as the empire expanded, ceramics changed in the society.

However, materials exhibiting ductile behavior ( most metals for example ) can tolerate some defects while brittle materials ( such as ceramics ) can fail well below their ultimate material strength.

However, nowadays non-professional cooks usually use much less expensive graters made from other metals, plastic, or ceramics.

However, it also a working industrial district and contains several potteries: ranging from Burleigh Pottery, the oldest working Victorian pottery ; to the art-driven Lorna Bailey ; to Steelite, a modern mass-production ceramics producer.

However, there is no certain evidence for sub-Roman occupation ( the supposedly post-Roman bead and ceramics appear to be of late pre-Roman Iron Age date ), and the apparently late remains ( a structure ) may as easily represent Roman period occupation.

However, their range of subject matter in all likelihood embraced more topics than those recorded in stone and buildings, and was more like what is found on painted ceramics ( the so-called ' ceramic codex ').

However used in ceramics for underglaze decoration it keeps its colour well, and is the main blue used in blue and white pottery from a wide range of dates and areas, including Chinese blue and white porcelain from the Yuan and Ming dynasties, Renaissance Italian maiolica and Delftware.

However, traditional ceramics like titanium dioxide ( TiO < sub > 2 </ sub >) and zinc oxide ( ZnO ) also form inorganic nanotubes.

However, for convenience we will stick to the idea that information can be classified according to Table 1.

However, the surface temperature gradient can produce erroneous vapor-pressure measurements for the bulk liquid helium unless precautions are taken to isolate the tube ( which passes through the surface to the vapor pressure bulb ) from the liquid helium surface.

However, the healthy inventory position of the textile industry lends support to the broadly expressed belief that improvement in that industry can be expected by the second half of 1961.
