Bearing Friction

The paper presents a theoretical approach and experimental analysis of bearings friction from a parallel axes transmission. The bearings are components of a testing rig for determining friction losses in chain drives, depending on the tensioning force, speed, temperature and quality of lubrication. Friction in chain is calculated by subtracting the bearing friction from the global (chain and bearings) friction. It is of maximal importance in the correct evaluation of experimental measurements on the rig, to have accurate data on the friction on bearings.

Chiral Structures

Recently we have developed a form of polarization microscopy that forms images using optical properties that have previously been limited to macroscopic samples. This has given us a new window into the distribution of structure on a microscopic scale. We have coined the name differential polarization microscopy to identify the images obtained that are due to certain polarization dependent effects. Differential polarization microscopy has its origins in various spectroscopic techniques that have been used to study longer range structures in solution as well as solids. The differential scattering of circularly polarized light has been shown to be dependent on the long range chiral order, both theoretically and experimentally. The same theoretical approach was used to show that images due to differential scattering of circularly polarized light will give images dependent on chiral structures. With large helices (greater than the wavelength of light) the pitch and radius of the helix could be measured directly from these images.
