The present study has been focused on the effects of the friction-mechanical treatment producing the fine size grain structure and the favorable internal stress state within the treated layer on the increase in resistance to corrosion, cavitation, wear and on hydrogen absorption by the treated surface layer of steels.
steels highly depend on the material structure and hardness.

For different kinds of plant fiber raw materials, the content and structure of hemicelluloses is quite different.
The reason is that wood structure was loosened by pretreatment which made chemical penetration easier and delignification faster.

The Corrosion Processes Effect on Surface Roughness of Bonded Magnetic Material Based on Nd-(Fe,Co)-B Powder Type Klaudia Radomska1,a*, Grażyna Pawłowska1,b and Dorota Klimecka –Tatar 2,c 1 Department of Chemistry, Faculty of Production Engineering and Materials Technology, Technical University of Częstochowa, Poland 2Institute of Production Engineering, Faculty of Managment, Technical University of Częstochowa, Poland a*klaudia_radomska@poczta.onet.pl, bpawlow@wip.pcz.pl, cklimt@wip.pcz.pl Keywords: surface roughness; bonded magnets Nd-Fe-B; biencapsulation.
Bonded materials obtained from powder after biencapsulation differ in structure and there are characterized with the different roughness parameters values [15], furthermore the different roughness can affects on their corrosion behavior.

Heterogeneous photocatalytic degradation of chlorophenols over Ag-TiO2 nano particles in an aqueous suspension Selvaraj Rengaraj 1 a, Jei-Won Yeon 1 , Xiang-Zhong Li2 , Yongju Jung 1 and Won-Ho Kim 1 1 Nuclear Chemistry Research Division, Korea Atomic Energy Research Institute, Daejeon 305-600, Korea 2 Department of Civil and Structural Engineering, The Hong Kong Polytechnic University, Hong Kong, China a Corresponding author: Srengaraj1971@yahoo.com Keywords: Chlorophenols; Photodegradation; Ag deposition; Sol-gel; TiO2; UV light..
The crystalline quality and crystal structure of the TiO2 and Ag-TiO2 samples were examined by XRD and the diffractograms are shown in Fig. 1.
The O 1s wide peak structure for Ag-TiO2 at 530.79 eV (FWHM 1.36 eV) is at a similar energy to the O 1s electron binding energy for TiO2, where a narrow peak has a slight asymmetry with a binding energy of 529.81 eV (FWHM 1.15 eV).

Up to now, many fuel vendors and utilities have made efforts to develop a high performance fuel with an improved economy and reliability by considering the development of new materials, improvement of the water chemistry, design improvement for strengthened grid structures, etc.
Above all, due to a high level radiation and an enormous expense, there are very few methods to confirm whether the wear-resistance is increased in the operating conditions of nuclear power plants when an improvement of the grid structures based on analytical studies is applied to the design of a fuel assembly.

Comparative study on metal/CFRP hybrid structures under static and dynamic loading.

Corrosion is a destructive and cost-bearing phenomenon for every industry dealing with metallic structures.
Multiphase pipelines of oil & gas gathering systems are more vulnerable to corrosion phenomena as a result of complicated water chemistry, presence of acid gasses such as CO2 and H2S, multiphase flow, etc.
