Abstract: A reaction system comprises at least one additive and at least one reaction base-plane for augmenting chemical reaction, photoelectrochemical reaction, photochemical reaction or electrochemical reaction. The reaction system further comprises at least one reaction substrate carried out to the chemical reaction, the photoelectrochemical reaction, the photochemical reaction or the electrochemical reaction with the at least one additive and the at least one reaction base-plane. The at least one additive is a kind of reaction enhancer added in the reaction system to improve, augment or accumulate the effeteness of at least one reaction result.

Abstract: A delay circuit for receiving an input signal and generating a delayed output signal. The delay circuit includes a first delay module and a second delay module. The first delay module includes a first delay unit for generating a first delayed signal according to an input signal and a first logic unit, coupled to the first delay unit, for generating a first delayed output signal according to the first delayed signal and the input signal. The second delay module includes a second delay unit for generating a second delayed signal according to the first delayed output signal and a second logic unit, coupled to the second delay unit, for generating the delayed output signal according to the second delayed signal and the input signal.
