Luz and Chaves (3) report that kaolin usually contains accessories, which may represent from 40% to 50% in volume of the extracted material, and sometimes even more than this.
Hydrocycloning is a modern process which is frequently used for the separation of materials based on the differences between the sizes of the particles, which is achieved with efficiency and low cost, separating the larger and denser particles from the smaller and less dense ones (8).

These materials have attracted considerable interest due to their unique physical properties, such as extremely high melting temperature and hardness, as well as high thermal and electrical conductivity [1-4].
Metallic behavior is exhibited for WZ type (B4), but the material is semi metallic for ZnS type (B3), which is a surprise and suggests that the material can be used for additional applications.
However, none of the materials exhibited a magnetic behaviour.

Introduction White organic light-emitting diodes (WOLEDs) have received significant attention due to their potential application in large area; full-color flat-panel displays and in next generation solid-state lighting source of energy-saving materials [1-3].
Herein, we report the synthesis of C-N and N-N ligands from Suzuki-Miyaura cross-coupling reaction where all products will be used as the ligands for synthesizing WOLEDs materials.
Material and method Chemical reagents and solvents were purchased from commercial suppliers and used without further purification unless noted.
This protocol is useful to synthesize C-N and N-N ligands in the synthesis of iridium complexes for synthesizing WOLEDs materials.

At the same time, due to the change in soil pressure along the height of the basement wall, it is recommended to use materials of two brands with dynamic modulus of 0,18 – 0,22 N/mm2 and 0,32 – 0,35 N/mm2.

Thermoelectric refrigeration (or thermoelectric cooling; TEC), as shown in Fig.1, is achieved when a direct current is passed from the n- to p-type semiconductor materials (Peltier effect).
The usefulness of thermoelectric materials for refrigeration is often characterized by the dimensionless thermoelectric figure of merit [2].
In the selection of a suitable TEC, the designs of the heat spreader and heat sink together with the interface materials could be crucial.

Introduction In recent decades, polylactide materials received the widespread attention due to its excellent properties, such as good biodegradation, biocompatibility and the non-toxic for organism.
Due to the emphasis on the non-toxic materials on the body, so whether they are raw materials or catalysts for catalytic reaction are to make use of low toxicity and even non-toxic drugs.
