Method and Materials Materials.
The study investigations were carried out at different speeds (800, 1200, and 1600 rpm) under the conditions set forth by the American Society for Testing and Materials (ASTM).
This figure clearly shows that the PFAD oil ball surface at 800 rpm was covered with small pits, which appeared on the ball surface due to materials transfer between contact parts, as reported by [18].

Introduction The stress concentration problems are encountered frequently where a sudden change of geometric dimension or material property takes place in the engineering structures.
This is because the actual materials have their own microstructure and intrinsic length scale, and the steep strain gradient may occur where stress concentration occurs.
Material parameters used are: elastic modulus E=, poisson's ratio .

CTS has a highly reactive amino group is a useful material for various purposes such as ion-exchange [2].
Recently, CTS derivative bearing β-CD has received considerable attention because its adsorption behavior is different from those of natural CD and CTS materials [3, 4].
Experiment Section A.Preparation of Chemical Modification of β-CD-g-CTS Unless otherwise noted, all of the raw materials were analytical purity and used as received without further purification.
