Cross-section TEM micrograph of a cBN film on single crystal silicon with the typical interlayers of amorphous material , turbostratic BN.

Cross-section TEM micrograph of the laterally overgrown GaN layer showing overgrown seed and wing areas

Cross-section TEM micrograph showing a coalescence of the N- and Ga-polarity wings and high density of defects in the seeds present in the laterally overgrown GaN layer which was

Cross-section TEM of a Fe V superlattice, showing well defined, smooth layers. Image taken from A. Broddefalk et al., Phys. Reu. B, 65 214430 .

Cross-section temperature distributions at several critical times of the left guide-wall dam section.

Cross-section throngh a speleothem showing annual deposits

Cross-section through .

Cross-section through a bulge in the copper cladding on a dress-cap note the white aluminum corrosion product and the thinned and cracked edge

Cross-section through a cylinder of stiff material embedded in an infinite extent of less stiff material. The stress state in the host is homogeneous but anisotropic at all points, except insofar as it is modified by the inclusion.

Cross-section through a double layer weave, showing the finer weave at the upstream .

Cross-section through a dry reagent slide for use in the Vitros Chemistry System, previously known as the Kodak Ektachem analyser. A range of slides, which vary in the nature, number and composition of the layers, is available for a variety of analytes in blood serum. The sample is applied to the spreading layer and reactions take place as it permeates through the various layers. Detection is by reflectance photometry.

Cross-section through a film of polypyrrole. The film was first embedded in an epoxy resin, then microtomed and finally subjected to a two-stage etching process to generate the required relief. The film can be seen standing proud of the embedding material in addition, internal texture is also apparent within the polypyrrole itself.

Cross-section through a fractal porous medium showing the configuration of the thin film phase in the pores. Only pores with sizes below the critical threshold level are entirely wetted. In the remaining pores the presence of the film phase is controlled by the magnitude of the adverse pressure

Cross-section through a melt channel in the melting zone of an extruder

Cross-section through a optical fiber chemical sensor composed of a fiber waveguide, an optically responsive workmg chemistry. The outer overcoat may he the optical isolation, or a layer of immobilized enzyme.

Cross-section through a pearl mill.

Cross-section through a planar optical sensor membrane composed of an inert solid support, and cm optically responsive sensor chemistry. A light source IS placed underneath the sensor along with a photodetector which measures the intensity of the light emitted by the sensing layer. Sensor membranes of that kind are used in flow cells as shown in

Cross-section through a reverse-flow hydrocyclone showing the typical flow patterns. The inset photograph shows a bank of six cyclones connected to a common feed manifold system.

Cross-section through a silica flake coated with Ti02.

Cross-section through a speleothem showing annual deposits of varying size

Cross-section through a staggered arrangement of micro fins designed for heat transfer enhancement in a micro channel , taken from .

Cross-section through a tent-shaped clinker store

Cross-section through a trap .

Cross-section through a typical prestressed-concrete liquefied natural gas storage tank.

Cross-section through Alloy 230 after 250 h at 950 C under decarburizing conditions
