- Slip on Superhydrophobic Surfaces (2010, background): “In these flows, the use of the no-slip boundary condition would produce a nonphysical result (Denn 2001, Dussan 1979), and a finite slip length is often employed, even in these macroscopic flows, to eliminate the resulting velocity singularity (Hocking 1976).”

- Recent experimental probes of shear banding (2008, background): “Although very informative, purely rheological studies do not allow to discriminate between shear banding and other possible space- and time-dependent phenomena that may occur in complex fluids such as wall slip [9,51], stick-slip [33,55,163], fracture [26, 85,93,121], tumbling in nematic materials [”
- Multiphysics modelling of manufacturing processes: A review (2018, background): “In both cases, stick and partial slip plays important roles in the sharkskin mechanisms.(64,65) At larger shear rates, the extrusion experiences a stick–slip instability (or spurt phenomenon), characterized by an alternation of smooth and rough surfaces of the extrudate, and oscillations of the pres”
- Perspectives on viscoelastic flow instabilities and elastic turbulence (2021, unknown): “The systematic analysis of these empirical observations by Pearson and colleagues, as well as Denn and colleagues, is particularly impactful in this regard; see, for example, the extensive reviews by these authors [90, 91].”
- Slip at Fluid-Solid Interface (2011, background): “The occurrence of slip can also be revealed by the presence of distortions; such as fluctuations, discontinuities, non-monotonic trends and nonuniform slopes; in the shape of rheograms and other flow characterization curves [11, 34, 49, 52, 53, 62, 63, 69, 71, 73, 80, 106, 118, 135].”
- An introductory essay on subcritical instabilities and the transition to turbulence in visco-elastic parallel shear flows (2007, background): “The dominant interpretations that have emerged are in terms of stick–slip phenomena at the wall [28], instabilities at the outlet of the extuder [28,30] or polymer-specific effects [55].”
