Polymer nanocomposites
Polymer/clay nanocomposites are materials composed of a polymer matrix and nanometer-size clay particles.
The processing of materials was performed in a Buhler twin-screw extruder BTSK 20/40D.
SEM structures of tested materials are shown on Figure 3 – Figure 5.
Form these images we can conclude, that while in the materials PA6/Cloisite 30A (A) and PA6/Cloisite 93A exfoliation took place, in the material with Cloisite NA + filler the clusters of particles and undigested filler is visible.

Abstract.
In addition, similar to traditional crystal materials with fcc structure, BMGs do not exhibit a ductile to brittle transition (DBT) as the temperature decreases, which is a well known phenomenon observed in crystal materials with bcc and hcp structure.
The materials start yielding at the onset of shear band formation.

Studies have shown that doping can change the optical, electrical and magnetic properties of ZnO semiconductor materials.
For example, doping Al, Ga, In and other elements can obtain n-ZnO materials with excellent electrical properties [11-13].

Introduction
Electrocatalytic oxidation has received considerable attention for the degradation of organic materials and other poisonous pollutants [1] because of its high efficiency [2], easy operation [3] and environmental benign [4].
However, materials used for stable anodes are quite limited in wastewater treatment.
Many researches had been investigated on anodic materials and various electrodes have been used for electrochemically degrading organic pollutants [7,8].
Experimental 2.1 Materials Stainless steel plates with the size of 50 mm × 25mm × 2mm were obtained commercially.

There are increasing interest in the spintronic materials recently, especially the half-metallic ferromagnets (HMFs).
HMFs possibly have higher magnetoresistance effect than ordinary magnetic materials since their spin-polarization at the Fermi level is much higher than that of ordinary magnetic materials.
Therefore, HMFs will have much wider application than ordinary magnetic materials[4,5].

An EN 10028-3 - P355 NH carbon steel plate 300 x 300 x 20 mm was cladded on one surface, using a filler metal 4 mm in diameter.
The submerged arc welding parameters are listed in Table 1 and the chemical composition of the materials is listed in Table 2.
Also the IHD is not limited to crystalline materials and it presents low sensitivity to material microstructure.
The authors are also grateful to ARSOPI S.A., Portugal, for providing base materials and welded specimens.

Due to recent EU environmental regulations regarding the biodegradability issues of polyolefins and the increasing in the recycling rate for this type of materials, thermorheologic parameters determination for plastic wastes is even more important than in the case of virgin polymers, because in this case the actual values of MFR is affected by the presence of polymeric impurities (due to inefficient separation), additives (dyes, plasticizers, stabilizers) or surfactants left over from the washing step of the waste material [6.
In this paper, the melt flow rate under different temperatures and piston loadings have been used to assess the rheologic and thermal behavior of two types of waste polyolefin materials, namely a fraction rich in HDPE and one with a high content in PP.
