Introduction Perovskite oxide thin films possess various novel properties and are considered as one of the most important material families to meet challenges of nanotechnology.
Therefore, interfacial structure and the lattice mismatch at the interface between the film and substrate play a key role in controlling epitaxial quality, microstructure and physical properties of the films.
The lattice misfit can be used to enhance the Curie temperature of high temperature superconductor [7], to alter the Curie temperature of ferromagnetic transition in CMR materials [8], magnetic properties of ferrite films [9,10,11,12], and the dielectric properties in ferroelectric materials [13].

The automation of finishing operations would result on direct cost and delivery time reduction which are key points.
Laser polishing process allows a reduction in the roughness by controlled melting of material.

(2011) [8] and demonstrated that the laser polishing process can be successfully applied in the polishing of various materials such as titanium, stainless steel or steel tools but there are no references on the application of laser polishing process in cast iron.
In this area the material presents a martensitic structure with an average hardness over 50 HRC.

Introduction 2,6-diisopropylnaphthalene (2,6-DIPN) is an important raw material for synthesizing new polyesters such as polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), and liquid crystal polymer (LCP).
Obtaining the 2,6-DIPN of high purity has become one of the research subjects urgently to be solved in researching and developing this new type of materials.
However, the key to obtaining the 2,6-DIPN of high purity lies in the preparation of highly-selective catalyst.
Experiment The preparation of catalysts Quantitative HM (H-SAPO-11, HZSM-5) molecular sieve powders were taken and put in a conical flask, and then the water-free ethanol solutions with different FeCl3 concentration were put in the flask based on the solid-liquid ratio of 1:10, and then these materials were stirred for 3 hours at refluence temperature.
