Experimental Materials.
The starting materials utilized are triblock copolymer Pluronic F-127 (EO106PO70EO106, MW=12600, Aldrich, product no.
Thus, the change in photocatalytic performance is not linked with the different specific surface area, and the enhancement of photocatalytic activity may be attributed to the more effective separation of the photogenerated electron–hole pairs of the composite materials.

Inorganic materials as catalysts for photochemical splitting of water [J].

The formation of a nanocrystalline material for this system after 50h of milling can be observed in Fig.3 40 nm Fig. 3.
After 1h of milling strong streaking is observed in the electron diffraction ring pattern as result of the heavy deformation in the material.

Introduction With the development of ultra-large scale integration (ULSI), device dimensions are becoming smaller and smaller, and the diameters of silicon wafer used as substrate materials are becoming larger and larger (up to ø300 mm).
In recent years, some polishing tests of hard and brittle materials in the presence of cryogenic polishing pad containing colloidal SiO2 slurry, nano-sized CeO2 or Al2O3 slurry were carried out and smooth surfaces with nanometer or sub-nanometer roughness have been obtained [5,6].

Moreover, the NS provides a deformation temperature decreased by 50 – 100°C as compared to the fine-grained material.
The data of heat treatment for the NS alloy correspond to the Aerospace Material Specification (AMS) requirements.
