Many work on dielectric materials focused on glass phases additions on dielectric compositions of type II.
She shows the linear nature of the dielectric constant, dielectric materials characteristic of type I, is still preserved.

Strain measurements were performed in vertical scan ("z-scanning") mode to provide a through thickness strain profile in the coating and substrate materials.
In this approach a composite beam of two materials, the substrate and the coating layer, can be assumed as perfectly adhered to each other.
As the coating substrate system is in equilibrium, the sum of forces in the two materials must be zero: 220 µm coating 6 mm substrate  Ec,s Ac,s (c,s T - x/l) = 0 (2) where1 E, A and  represent the Young's modulus, cross-sectional area and CTE of the coating and substrate materials.

Thus, those materials generally fracture in brittle mode under load.
Those critical values are inherent to the workpiece materials.
Various brittle materials are capable of ductile behaviour under high external hydrostatic pressure [17].

The nanocomplexes materials were characterized by TEM, with a particle size around nanoscale particle sizes (~50 nm) with high dispersion phenomena.
The experimental results show that the Cu-La-Ce nanocomplexes materials only minor cause cytotoxicity effect in cultured human cells.
Rather, in this case, studies on cytotoxicity are available, especially for copper-group materials that have been used for decades, but very little is known on the toxicological effect and interaction with cellular structures for most newly developed materials.
Generally, these crystal phases may be responsible for the marked activity of materials.

Up to now, there are three main electrode materials developed for supercapacitor: carbonaceous materials [1], transition mental oxides/hydroxides [2] and conducting polymers [3].
Previous reports have shown that in mixed valent manganese materials Mn(+III) forms the most reactive sites[11, 12].
And our results show that the as-prepared γ-MnOOH nanowires exhibit good electrochemical properties as electrode materials for supercapacitor.
The high capacitance, good electrochemical properties and environmentally benign of γ-MnOOH nanowires makes it attractive as electrode materials for supercapacitor.

Introduction Relaxor ferroelectric material was widely used in the application like actuator with huge electrostriction properties and electrooptic application due to large Kerr effect [1,2], for examples PMN-PT and PLZT materials.
Induced-strain properties of piezoelectric and electrostrictive materials can be measured by the high resolution the Michelson interferometer.
