Tóm tắt	Electrochemical Impedance Spectroscopy (EIS) is a powerful technique for characterizing electrochemical systems by applying a small AC voltage over a range of frequencies and measuring the resulting current response. Developed in the late 1960s, EIS reveals the frequency-dependent resistance and capacitance of interfaces, allowing researchers to separate charge transfer kinetics, diffusion, and ohmic losses. It is widely used in battery research, corrosion studies, fuel cells, and biosensors.	Light curve analysis is the study of the brightness variation of a celestial object over time, used to detect and characterize exoplanets, eclipsing binaries, and variable stars. When a planet transits in front of its host star, the star's brightness dips slightly. By analyzing these photometric signatures, astronomers can determine planetary radii, orbital periods, and atmospheric properties. This method has discovered thousands of exoplanets and revealed the structure of stellar systems.
