layer

[′lā·ər]
(computer science)
One of the divisions within which components or functions are isolated in a computer system with layered architecture or a communications system with layered protocols.
(geology)
A tabular body of rock, ice, sediment, or soil lying parallel to the supporting surface and distinctly limited above and below.
(geophysics)
One of several strata of ionized air, some of which exist only during the daytime, occurring at altitudes between 30 and 250 miles (50 and 400 kilometers); the layers reflect radio waves at certain frequencies and partially absorb others.
(metallurgy)
The stratum of weld metal consisting of one or more passes and lying parallel to the welding surface.

1. A layer of masonry units running horizontally in a wall or, much less commonly, curved over an arch; it is bonded with mortar.
2. A continuous row or layer of material, as shingles, tiles, etc.

Table 4 shows the grey relational grade and its ranking for the Ti[O.sub.2] compact layer coatings.
In contrast, without the Ti[O.sub.2] compact layer (only porous Ti[O.sub.2]), the peak intensity of the anatase (101) plane in the XRD patterns for the Ti[O.sub.2] film has a lower value, which demonstrates inferior crystalline quality.
Figure 6 shows the photo current-voltage (I-V) characteristics for the DSSC under AM1.5 solar irradiation with 100 mW/[cm.sup.2] illumination, with and without the Ti[O.sub.2] compact layer. Figure 6(a) shows a carbon counter electrode and ITO/glass, Figure 6(b) shows a Pt counter electrode and ITO/glass, and Figure 6(c) shows a Pt counter electrode and FTO/glass [24].

In this case the presence of the nanoparticles may limit the accessibility of the electrolyte to the bottom of NTs (compact layer), and in turn the contribution of bulk sites is excluded.
The results could be justified by considering that in this case the availability of the bulk sites is not hindered, since the compact layer of the oxide is directly connected to the particles of the decoration, so that eliminating the solution does not compromise the global efficiency but rather leads to a beneficial effect in terms of reduced global impedance.
