Acceptor-doped lanthanum manganite materials have a potential in application of electrochemical devices [7].
In addition, this general class of materials, displays interesting and potentially useful catalytic and magnetoresistant properties.
Due to the high conductivity of manganites-based perovskite, there are only a few studies on the dielectric properties materials [10].
MATERIALS AND METHODS Material with general formula La0.7Sr0.3Mn0.4Ti0.6O3 was prepared using the solid state reaction method.

Introduction In general, nanoporous materials, such as zeolites, are usually utilized in adsorption, separation, ion-exchange heterogeneous catalysis and other desired functions.
Zeolites are microporous crystalline materials with an inorganic, three dimensional host structure comprised of fully linked, corner-sharing tetrahedron.
Fig. 1 Silicalite-1 Fig. 2 Schematic view of molecular spring isolator In present, researches on molecular spring are mainly concentrated on synthesizing new materials [6] or molecular simulations of water adsorption in zeolites [7].

High density oxygen-plasma etching and pico-second laser machining were developed to make micro-texturing onto the above two mold-die materials.
In the present paper, two amorphous carbon materials are selected as a mild-die material to be micro-textured: DLC coating and glassy carbon.
Using this glassy carbon mold-die, original micro-texture was duplicated onto PMMA (Poly-Methyl-Meta-Acrylate) sheet via the micro-mold-stamping system. 4.1 Micro-Texturing onto Ceramic Materials When using the micro-second or nano-second laser machining, almost all the substrate materials suffer from the heat affection where the laser beam has interaction with raw material abrasion.
