A high-resolution Nmany types of molecules ingeniously arranged in a transmission electron microscopic (HRTEM) image of a sample nanospace, highlights the importance of a technique for site- prepared by irradiation (lex 320 nm) of a de-aerated S8 ethanol selective coupling of different materials to realize artificial solution containing Au/TiO2 particles in the presence of Cd2+ high-efficiency devices1. In view of increasingly serious energy ions shows that a hemispherical core–shell-type nanoparticle is and environmental problems, semiconductor-based artificial formed on TiO2 (Fig. 1a). The lattice spacings of the core and shell, photosynthetic systems consisting of i
