First, the instantaneous availability of a larger number of sites for VWF binding to platelets, that is, the higher strength of adhesive bonds, may positively support platelet binding to VWF and eventual activation. Second, the larger size of these molecules may result in larger forces acting on...
The four biomaterials that were explored include: silicon, silicon coated with a nanoscale layer of titanium, Ti–6Al–4V, and poly-di-methy-siloxane (PDMS). The interfacial strengths between the HOS cells and the biomaterials surfaces were determined using a shear assay technique. The adhesion ...
pH (9), ionic strength (10), or surface chemistry (11). Although the effect of the shear has been addressed in the context of biofilm formation and biomass accumulation (12,13), few studies have focused on the effect of flow on ...
investigated by an instrumented peel test, along the lines of Newby and Chaudhury's work (Langmuir 1997 , 13, 1805-1809;Langmuir 1998, 14, 4865-4872), which gave the first evidence of interfacial slip when a pressure-sensitive adhesive is peeled from a thin poly(dimethylsioxane)(PDMS)layer...
As an example the strength of single vs double chains has been compared for both the dipolar approach and a multipolar calculation. In the dipolar approximation the double chain structure seems strongest. However, multipolar calculations show that the single chain structure is stronger than the ...
Rheological analysis of the molecular chain, the melt strength characteristics of the polymers, and basic research and development work are possible with this equipment. The extrusion barrel temperatures used in this test are the same injection molding barrel temperatures used in production for grades ...
contraction angle showed a shear-dependent occlusion and lag time for both PRP and WB. This shear-dependent behavior of the platelet aggregate formation might be caused by the stenotic geometry. Similar content being viewed by others Material strengths of shear-induced platelet aggregation clots and...
It is correlated to the force strength applied on the sample surface by the tip. The typical value of setpoint value for this device in scanning silicon wafer is 0.3, which should be decreased accordingly as the sample modulus decreases. The PGain is used to amplify the error signal, and ...
considering that an atomic-thick vdW stack often has the same type of deformation under a macroscopic load, it is of great significance to study the relative in-plane deformations of all its layers, that is, the shear deformation and the corresponding interfacial shear strength (ISS) of the st...
The biological responses elicit due to either force transmitted via adhesion proteins (Integrin, Cadherin) of cell membrane or in presence of fluid shear stress being transmitted directly to the cell membrane and the receptors present on surface13,14. Material strength of the cells, sensing ...
