The dependence of Seebeck coefficient on roughness parameters suggest that it can be tailored by choosing the appropriate roughness parameters.

Coefficient of friction, roughness, and adhesion energy toward a colloidal AFM probe [ 16, 17] on brushed and unbrushed SCFs were measured with an AFM (Nanoscope IV DimensionTM 3100) equipped with a Dimension Hybrid XYZ SPM scanner head (Veeco, NY, USA).
The correlations found between coefficient of friction, surface roughness of the wear scar, tribofilm formation and contact conditions are discussed.
The effects of four control factors i.e., load, SiC abrasive grit size, sliding distance and sliding velocity on three tribo-responses i.e., wear rate, coefficient of friction and roughness of worn surface have been investigated separately for base alloy and composite using pin-on-disc tribometer.
Wear and adhesion properties seem to be related and mainly controlled by the brittle or tough nature of the coating as well as by the nature of the substrate/coating interface, to a lesser degree by coating hardness, and only marginally by the coating coefficient of friction and roughness.
Barton and Choubey (1977) provided joint roughness coefficient (JRC) of rough fracture asperities in the form of an irregular zigzag line in real coordinates for visual determination of the JRC for different rock types (Barton and Choubey (1977); Barton and de Quadros 1997).
Experimental investigation concerning the variation of roughness coefficient of meandering channels with flow depth, aspect ratio, slope and sinuosity are presented in this paper.
Apart from the measurements, bed load transport rate was computed by means of Meyer-Peter and Müller formula, after calibrating the above formula in terms of roughness coefficient.
Algorithm-derived estimates of river bathymetry were validated using in situ measurements, and estimates of roughness coefficient were compared to those used in an operational hydraulic model.
