Abstract: This paper describes an invention involving an electrochemical discharge-enabled micro-grinding process for micro-components of silicon-based materials. The specific machining method is described below. A micro-grinding tool and an auxiliary electrode are respectively connected to the negative and positive electrodes of a pulsed DC power supply. When the current flows through the loop, an electrochemical hydrogen evolution reaction (HER) occurs at the micro-grinding tool in the grinding fluid, which generate multiple hydrogen bubbles. The bubbles coalesce into an insulating gas film and separate the micro-grinding tool from the grinding fluid; when the critical voltage is reached, the gas film is broken down and an electrochemical discharge occurs accompanied by discharge spark; under the action of the discharge spark, the surface material of the workpiece in the discharge-affected region is directly ablated to generate a heat-affected layer (HAL), namely, physical modification.

Abstract: A method and a sensor for detecting L-arginine are provided. The method includes synthesizing ferrocene-functionalized hexadecapeptide dithiocyclopentane (FC-P16 Peptide), preparing a polypeptide composite membrane-modified electrode (FC-P16 Peptide/AuE), detecting L-Arg and other steps. The results show that the polypeptide composite membrane-modified electrode (FC-P16 Peptide/AuE) exhibits excellent electrochemical response properties to L-Arg. In 10 mmol/L phosphate-buffered saline (PBS, pH=7.4), the DPV response peak current of the polypeptide composite membrane-modified electrode has an excellent linear relationship with the L-Arg concentration of 1.0×10−13 mol/L to 1.0×10−7 mol/L, with a detection limit of 1.0×10−13 mol/L. With prominent reproducibility, repeatability and selectivity, the modified electrode has potential application in life science and nutritional health.
