Fracture strength is one of the key mechanics performances for engineering ceramics products, greatly influenced by the microscopic topography and residual stress field of ground surface.
Up to now, grinding with diamond wheel is the normal technique for machining high hard-brittle ceramics materials [2].
However, since the hard-brittle characteristic of engineering ceramics, the polishing efficiency for ceramics was lower than many other materials.

Electrostatic stresses are a fascinating field where materials science, continuum mechanics and electrical engineering all come together.
This treatment of electrostatic Maxwell stresses is restricted to the macroscopic description of the phenomenon, but an attempt is made to provide readers with methods and results which will allow them to deal with cases of low material symmetry, as well as with the effect of viscoelasticity upon the material response.
Non-standard orientation of the material sample is studied in detail, because it is commonly encountered in laboratory practice, or is intentionally chosen so as to optimize a given device.
A key advantage of the analysis presented in this book is seen in the fact that it permits the materials scientist who is planning experiments, or the technician who is designing novel electromechanical actuators, to predict the electrostatic stresses in terms of material constants.

Thus, providing an experimental foundation accelerated the formation of bands of Bünger to enhance nerve regeneration. 305 nm SFS could be a candidate material for nerve tissue engineering.
Due to unavailability of ideal scaffold material and limited knowledge of cell and scaffold interaction, there have been limited breakthroughs in nerve tissue engineering [4].
These results may indicate that SF nanofibers were functionally active in terms of Scs cell attachment and spreading, and a promising candidate scaffold materials for tissue engineering.

Impact of Initial Titanium Magnetite Ore Material Composition on Fluxed Pellet Metallurgical Properties Boris P.
The work results are of certain interest for the process engineers and specialists dealing with iron ore raw material preparation, as they allow forecasting of high quality fluxed pellet production from various material composition concentrates.
The marked difference in the type of the pellet strength dependence on the roasting temperature observed in the experiments with the wehrlite pellets is attributed to the excess slag-forming oxides in the pellet charge materials.
