Introduction Positrons have tremendous potential in many fields of science, including chemistry, physics, materials science, surface science, biological sciences and nanoscience [1-7].
The value depends on geometry (transmitting or reflecting), crystalline structure (polycrystalline or monocrystalline), form (foil, mesh, fins etc) and thermal treatment.

A Theoretical Study of the O (3P) + HCONH2 Reaction Xiang Tiancheng*, Si Hongyan School of Chemistry and Chemical Engineering, Xuchang University, Xuchang 461000, China xtc@iccas.ac.cn Keywords: DFT calculations, reaction mechanism, O (3P) radical, HCONH2 Abstract.
Introduction As the importance atmospheric pollutants, NOx’s generations have been attracting long time attention in atmospheric chemistry and combustion chemistry.
The mechanisms for the following exothermic product channels are revealed for the first time, viz.: O(3P)+HCONH2→HNCO+H2O →HCHO+HNO →CO2+NH3 →OH+CONH2 Some small molecules and radicals produced from the above reaction, such as HNCO, HNO, have been proposed to participate in several important processes in the combustion chemistry of nitrogen.

The structures of phytolithes are characterized by the methods of optical microscopy and scanning electron microscopy.
For example, silicateins and silicase can form and destroy inorganic silicon-based structures [7].
The shape and size of phytoliths are extremely diverse, but, as a rule, for certain families and genera of plants is characterized by its distinctive structure of phytoliths.
These hexagonal structures can be used in microelectronics and optics, because they have a clearly oriented shape and repeatable size.
