Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Drag Coefficients of Oceanographic Mooring Components [PDF]
Journal of Atmospheric and Oceanic Technology, 1986 The inclination of oceanographic mooring lines due to current drag causes errors in time series observations of currents and temperatures. The prediction of this effect requires knowledge of the drag coefficients for the mooring components. Drag coefficients, known for simple geometric shapes such as spheres or cylinders, are commonly used for mooring ...
