of the perovskite absorption layer material is obtained; (3) the precursor liquid obtained in step (2) is spin coated on the surface of a substrate through a spin coater and after annealing at 150 DEG C, the chlorine-bromine-iodine-mixing perovskite light absorption layer material is obtained...
The halogens (fluorine, chlorine, bromine, and iodine) can combine directly with hydrogen to form the strong acids, hydrofluoric, hydrochloric, hydrobromic, and hydriodic; the latter three are particularly important in the manufacture of photographic emulsions....

Ozone in the atmosphere has considerable impacts on the climate system. Changes in ozone in the stratosphere and troposphere cause significant fluctuation in the global radiation budget for both the short-wave and long-wave. Although chemical reaction me
Killing of Chlorine-Resistant Bacteria by Chlorine-Bromine Solutions The disinfective power of chlorine, bromine, and mixtures of chlorine and bromine at different ratios was compared. The influence of pH was also studied. T... H Farkas-Himsley - 《Appl Microbiol》...
