Rough Surface Interactions of Micro/nano-Scale Contact Systems
… experimental measurements of dynamic interactive forces such as pull-in and pull-off force have been performed using a newly developed instrument, where two piezo-electric actuators were used to control normal and tangential motions of the contacting bodies and the interactive forces were measured …

Elastic Analysis of the Loop Tack Test for Pressure Sensitive Adhesives
… compressing the adhesive. Then the loop is pulled up, and gradually debonds from the substrate. The loop is assumed to be nonlinearly elastic and inextensible. The mechanics of the loop tack test are studied in order to determine the impact of various factors on adhesive performance. These …

High Speed Atomic Force Microscopy Techniques for the Efficient Study of Nanotribology
… second method rapidly acquires friction versus force curves through disabling the feedback loop during scanning and relating the resulting lateral data with the correspondingly varying normal loads. The third and most widely applicable technique rapidly creates a map of friction-force curves …

Nano-scale evaluation of moisture damage in asphalt
… measurements are conducted using an Atomic Force Microscope (AFM) in the laboratory. In an AFM test, adhesion forces of dry and wet asphalt samples are measured by probing the sample surface with AFM tips. Nano-scale pull-off force or adhesion between sample molecules and tip molecules are …

Surface and interface engineering in quantum dot and double-heterojunction nanorod light-emitting diodes
… at temperature below Tg the SMP exhibit large pull-off forces, enabling rate-independent patterning of the QD films. Photolithographically patterned PR stamps are also explored for patterning QD films. The glassy state of the PR provides rigidity that ensures normal stress to be more evenly …

Interfacial debonding from a sandwiched elastomer layer
… firmly bonded to a rigid base. The adherend is pulled upwards by applying normal displacements either on its entire unbonded surface or on the edge of its part overhanging from the elastomer layer. The adherend and the elastomeric layer materials are assumed to be linear elastic, homogeneous and …
