Carbon monoxide (CO) is a commonly poisonous gas.It is important to detect CO in Artwork daily life.Herein, a new and sensitive surface enhanced Raman scattering (SERS) and resonance Rayleigh scattering (RRS) coupled di-mode method was developed for CO, based on gold nano-enzyme catalysis and gold nanoprobes.CO can react with HAuCl4 to generate gol
Sonqor Koliyaie is a mountainous plain in central Zagros that has attracted the attention of human societies because of its appropriate environmental characteristics from long ago.Generally, the findings obtained from systematic archaeological surveys show that human settlements have been established in this area from Middle Paleolithic period thro
Marker substances for the coal mining industry were identified as an information and technical reference book to Drinks Pail the best available technologies for coal mining and processing.Inorganic dust when emitted into the atmosphere is defined as a marker substance for the coal industry.Inorganic dust emissions belong to the group of fugitive em
Abstract The feather-like hierarchical zinc oxide (ZnO) was synthesized via trinity-men successive ionic layer adsorption and reaction without any seed layer or metal catalyst.A possible growth mechanism is proposed to explain the forming process of ZnO feather-like structures.Meanwhile, the photo-electronic performances of the feather-like ZnO hav
