The relationship between contact resistance and contact force on Au coated carbon nanotube surfaces under low force conditions

, 2009
Carbon-Nanotube (CNT) coated surfaces are investigated to determine theelectrical contact performance under low force conditions. The surfaces under investigationare vertically aligned multi-walled CNTs formed on a Silicon substrate and coated with anAu ...

Contact Sensing from Force Measurements [PDF]

The International Journal of Robotics Research, 1993
This article addresses contact sensing (i.e., the problem of re solving the location of a contact, the force at the interface, and the moment about the contact normals). Called "intrinsic" contact sensing for the use of internal force and torque mea surements, this method allows for practical devices that provide simple, relevant contact information in

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Identification method of wheel-rail two-point contact state in switch area

Scientific Reports
Two-point contact is one of the fundamental problems of wheel-rail contact in switch area. The contact state and the distribution of forces are complex and essential points in wheel-rail relationship. Given the problem that the current dynamic wheel-rail

Numerical and Experimental Analysis of Potential Causes Degrading Contact Resistances and Forces of Sensor Connectors for Vehicles

IEEE Access, 2019
Faults in vehicle sensor connectors are crucial to the safety of a vehicle. Once the connector is loosened according to the reduction of its contact forces, its electrical contact resistance may be increased, causing unexpected errors in sensor systems ...
