It has been well known that bone has piezoelectric properties and these properties have been considered to be caused by the shift of the center of symmetry of the positive and negative electrical charge due to the strain of the collagen fibers included in the bone.
Introduction It has been well known that bone has piezoelectric properties[1] and it has been said that this properties affect the process of growth and the remodeling of bone.
In the authors’ previous report, HAp thin films were deposited on a Ti or Pt substrate using PLD method, and piezoelectric properties of the HAp film were estimated by measuring vibration responses of the mechanical strains and electrical voltages of the HAp structure simultaneously[5].
Further experiments were needed to establish the fabrication method of HAp films with excellent piezoelectric properties, which are currently ongoing projects.

The development of composite asymmetric membrane is a major breakthrough in membrane research field, as this membrane offers significantly high selectivity without affecting the mechanical durability of the membranes.
Depending on these factors, the effective strategies should be selected to control the fouling [27].
Furthermore, mechanical properties and durability of cellulose composite membrane are maintained by incorporating different additives such as nanoparticles [61], carbon nano tubes (NTs) [62] and silica [63].
The benefit of using composite membranes is that by tuning the thickness of both hydrophobic and hydrophilic layer, parameters such as mass transfer rate, heat transfer rate and mechanical properties can be controlled.
The key advantage with the thin film composite membranes is its high selectivity without compromising the mechanical properties of the membranes.
