ELECTROMAGNETIC NON-CONTACT GEARS: PRELUDE [PDF]
We calculate the lateral Lifshitz force between corrugated dielectric slabs of finite thickness. Taking the thickness of the plates to infinity leads us to the lateral Lifshitz force between corrugated dielectric surfaces of infinite extent. Taking the dielectric constant to infinity leads us to the conductor limit which has been evaluated earlier in ...

Adsorbate induced enhancement of electrostatic non-contact friction [PDF]
We study the non-contact friction between an atomic force microscope tip and a metal substrate in the presence of bias voltage. The friction is due to energy losses in the sample created by the electromagnetic field from the oscillating charges induced ...

Non-contact friction between nanostructures [PDF]
We calculate the van der Waals friction between two semi-infinite solids in normal relative motion and find a drastic difference in comparison with the parallel relative motion.

Non-contact infrared thermometers [PDF]
I wrote a letter to the BMJ last year setting out the evidence for non-contact infrared thermometry in adults.1 Unlike paediatric use,2 my conclusion was that these devices are not reliable in adults, largely because vasoconstriction of the blood supply to their foreheads and perspiration leading to a dangerously high false negative rate.

Non-contact ultrasonic detection of angled surface defects [PDF]
Non-destructive testing is an important technique, and improvements are constantly needed. Surface defects in metals are not necessarily confined to orientations normal to the sample surface; however, much of the previous work investigating the ...

Non-contact atomic force microscope: Modeling and simulation using van der Pol averaging method [PDF]
Topic and aim. One of the tools which are extremely useful and valuable for creating a topography of surfaces, measuring forces, and manipulating material with nano-meter-scale features is the Atomic force microscope (AFM).
