Because of this, mechanical properties of fibers can be reduced, so it is not suitable for use fibers as reinforcement in any composite materials.

On the other hand, although the motional impedance of piezoelectric-based microresonators can be below 50Ω, the Q factor cannot be very high due to high loss in the piezoelectric materials [3].
PnC resonator was proposed as a potential candidate to overcome the aforementioned trade-off between Q factor and motional impedance as PnC can store elastic energy in microcavity made on high Q materials such as silicon [12].

With the improvement of precision of machining equipment such as CNC machine tool and the appearance of super hard cutting tool materials such as PCBN and PCD, hard cutting has become a new machining method for quenched steel.
With the increase of feed rate, cutting temperature and material removal rate will heighten, plastic deformation of the workpiece in the cutting process will enlarge, causing the larger residual compressive stress produced on the surface of GCr15 steel.

Villa Živković, new design proposal- circular atrium that allows undisturbed growth of pine trees The use of glass as a material primarily serves to emphasize the absence of classical walls and constructions, and therefore the absence of the building in the classical sense, as we recognize it.
Introducing innovative materials and inventive techniques, this approach to revitalization is the proposal of contemporary method of preservation of architectural heritage, but it is also recognized and perceived as the most direct and the sincerest act of glorification of important cultural heritage building.
