This chapter covers the various methods for measuring the surface finish. The surface finish and texture can be measured in a large number of ways by using various instruments and techniques. Profilometry techniques are divided in two classes: those used on- or in-line and those used in the ...
A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter. Ha...
Graphene energy transfer (GET) can be used to measure the distance between a graphene surface and a fluorescent dye. A new strategy for attaching DNA in a controlled orientation onto graphene now makes it possible to use GET to track the dynamics of DNA and protein–DNA interactions with base...

The coating must have sufficient wetting properties to penetrate into the pores of the surface and to wet around the fibers of the substrate. Solvent blends of the coating system allow the coating to burn into coating layers within the system. Resin properties of the coating vary and affect ...
Surface casing vents divert natural gas migration along oil and gas boreholes to bypass groundwater, with the gas venting to the atmosphere. While this strategy is designed to protect groundwater, it constitutes a source of greenhouse gases to the atmosphere. In instances where gas leakage occurs...
Measuring surface roughness As an alternative to monitoring aqueous species in solution, it is possible to quantify the rate of dissolution by measuring the reduction in mass or volume. Mass loss can be measured simply by drying and accurately weighing a sample before or after dissolution but, whe...
With the extensive application of optical parts in many high-tech fields such as high-power laser, space optics, and aerospace, the requirements for the surface quality of optical parts are also increasing, which requires not only high surface qualities but also low defects including low subsurface...
(GIS) to form a protective layer on the surface, and the RP was etched beside the selected region. Afterward, 3D confocal images of this region were acquired. On the projected LM via FIB image, we measured the distance between a selected QD (as the TOI) and the center of the RP (...
hardwoods must be sealed periodically to provide a surface finish protecting against penetration of moisture by the otherwise naturally absorptive wood surface. Even typically more durable engineered wood laminate flooring, suffers from water/moisture damage because no glue or other moisture resistant filler...
