On the contrary, its disadvantage is its sensitivity to presence of some substances influencing the process of hydration reactions resulting in solid structure formation.
The low resistance to actuation of corrosion factors is another disadvantage. [7] This paper presents just a part of laboratory testing of project devoted to finding an optimum solidification formula with use of cement for hazardous waste – neutralization sludge – by monitoring a short-term properties of the solidification process product in time and by studying the micro structure of the solidification process product.

Plasma treatment affects the capillary-porous structure of the wood by changing it in the direction of increasing capillarity in the material and increasing its porosity.
The obtained microphotographs of wood show the change of the material structure and the splitting of fibers.

Despite the diversities of the chemistry and the compositions, the process of polymer materials applied in microelectronics is a little either complicated or non-compatible with basic microelectronic process [4,5].
The specific geometric dimensions of metal microcantilever structure without and with whole-wrapped electrophoretic polymer coating are illustrated in Figs.5.
As well as a good buffer layer, the perfect properties of multi-surface coating show a potential for the complex structure applications in microelectronics.
