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.

Abstract: For more than 80 years, although the traditional Proportional-integral-differential (PID) controller and all kinds of improved PID controller have been in the leading position in the field of industrial control, and played a huge role, but the tuning of the three gains for PID has been a prominent problem in the field of control theory and control engineering, and the lack of anti-disturbance ability. The intelligent PID or wisdom PID (WPID) control method of the invention establishes the tuning rule of three gains for PID controller through the speed factor irrelevant to the controlled system, which effectively solves the tuning problem of the three gains for the traditional PID, and has the global robust stability and good anti-disturbance robustness. The invention subverts the control theory system of nearly a century, and has a wide application value in the fields of electric power, transportation, machinery, chemical industry, light industry, aerospace etc.

Abstract: The present invention discloses a method for operating a multi-bar linkage mechanism based conveyor. Stretching the mechanism based conveyor comprises: an automatic control system is started to control a first two-drum winch, a second two-drum winch, and hydraulic cylinders in a multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters an operating state, and the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom stop operating. Then, the angle of the multi-bar linkage mechanism based conveyor boom can be adjusted by controlling the operation of the second two-drum winch. Retracting the mechanism based conveyor comprises: the automatic control system is started to control the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters a non-operating state.

Abstract: The present application discloses a single-point diamond dresser for a grinding wheel based on acoustic emission online monitoring, which includes a support module, an anti-interference module, a compression cooling module and an acoustic emission online monitoring module. An acoustic emission sensor monitors the dressing state of the grinding wheel online; a damping sheet and a damping interlayer greatly reduce external noise interference; a high pressure coolant causes an upward elastic deformation of an elastic spacer and the damping sheet, enlarging a contact force between the acoustic emission sensor and the core and moreover improving a sensitivity of the acoustic emission sensor; the coolant flows through the coolant passages in the core to cool a dressing area; current limiting passages, pressure relief cavities and perforated pressure-relief plates limit flow and reduce a pressure of the coolant, reducing the interference of the coolant on the grinding wheel dressing.

Abstract: A method for a selective detection of L-tryptophan (L-Trp) using formaldehyde as a medium is disclosed. The method includes preparation of a copper sulfide nanosheets-chitosan/acidified functionalized multi-wall carbon nanotubes (CuS NS—CS/F-MWCNTs) composite material, preparation of a composite film-modified electrode CuS NS—CS/F-MWCNTs/GCE, and a detection of the L-Trp. Since oxidation peaks of L-Trp and L-tyrosine (L-Tyr) overlap and are difficult to separate, the present invention provides a method for a highly selective detection of L-Trp through the Pictet-Spengler reaction of formaldehyde (HCHO) with L-Trp, in which the oxidation peak potential of L-Trp is shifted to 0.82 V and the oxidation peak potential of L-Tyr is 0.63 V, thereby effectively avoiding the interference of L-Tyr. The CuS NS—CS/F-MWCNTs/GCE is applied to detect L-Trp in the formaldehyde medium without any interference from L-Tyr or other amino acids with 50-fold concentrations.
