One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 144750-42-5, Name is (S)-2-(2-Chlorophenyl)-2-(6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)acetic acid hydrochloride, formurla is C15H15Cl2NO2S.

New Insight into Charge-Transfer Enhancement for SERS in Cosputtering (Ag)(x)(ZnS)(y) System: The Carrier Density Effect
Cosputtering technology was utilized to combine Ag with ZnS at different doping contents into a new material, which was referred to as the (Ag)(x)(ZnS)(y) (x = 10 W, y = 20, 40, 60, 80, 100 W) system. The carrier density is characterized through the Hall effect, and the change in the bandgap distribution due to the change in carrier density is calculated by ultraviolet photoelectron spectroscopy (UPS). By increasing the sputtering power of the ZnS in the (Ag)(x)(ZnS)(y) system, the carrier density and the conduction band (CB)/valence band (VB) were decreased. Interestingly, we found a liner relationship between the surface-enhanced Raman scattering (SERS) intensity ratio of b(2) to a(1) bands and the carrier density, which intuitively expresses that I-b2/I-a1 increases as the carrier density decreases. The development of the carrier density regulation of SERS materials can be used to monitor the possible CT enhancement for SERS.
