Espert et al [7] were mentioned regarding 3 mechanisms of moisture penetration into composites materials.
Wang et al [9] used percolation theory to get better understanding on moisture absorption mechanism of in natural fiber reinforced composites.
Eligon et al [10] have mentioned that in wood, adsorption and desorption of moisture under constant temperature exhibit hysteresis.
In this situation, water penetration by the means of capillary and micro crack mechanism is minimal as mention by Espert at el [7].

Sinha et al. studied the use of chitosan as carrier for various classes of drugs such as antihypertensive agents, anticancer agents, proteins, peptide drugs, and vaccines [3].
Shirosaki et al. previously prepared chitosan-3-glycidoxypropyltrimethoxysilane (GPTMS) hybrids and pointed put that they exhibited better cytocompatibility than chitosan membrane [4].
Moreover, Davis et al. described that epoxy groups and silanol groups formed Si-O-C bond, and the peaks detected at 60 ppm [7].
Akbugal et al
[8], or Bodmeier et al. [9] reported that the release of the drug from the microspheres decreases with increase in drug content in the microspheres.

Compacting pressure affects significantly the value of specific electrical resistivity, what in turn has a substantial effect on eddy current loss (dominant at increased excitation frequencies), as discussed previously by Lefebvre et al. [11] and Saito et al. [12].
De Wulf et al. [16] have considered the possibility to introduce a correction factor for conductivity.
A similar homogenization scheme, but for a spherical particle shape, has been advanced by Taghvaei et al. [17].

El-Ghossain [14] used SRIM-2008 to study the interaction of He ions with body tissues and bodily fluids at the 10 keV–10 MeV ion energy range.
Mei et al. [16] varied doses for He–BFO irradiation, resulting in larger ferroelectric coercive fields as doses were increased.
Tyagi et al. [5] have investigated SO₂ gas detection efficiency of SnO₂ thin film sensors with heavy Ni7+ion irradiation.
Singh et al. [17] have studied the tuning of defects induced photoluminescence in Ni-irradiated and Au-irradiated ZnO films.

Using ultra-fine-grain carbide tools, Wu Zhenyu et al. [10] investigated the milling forces, machined surface roughness, tool wear on wt.15%SiCp/Al composite in the milling speed range of 10-180m/min.
Suresh Kumar Reddy et al. [12] conducted the milling experiments on wt.20%SiCp/Al composites using TiAlN coated carbides to study the machined surface quality and machined induced defects.
The milling speed used was in the low or moderate level and never exceeded 300/min for SiCp/Al composites.
In addition to the defects mentioned above, when high-speed milling SiCp/Al composites, there also existed some depth of deformation layer on the machined surface.
