Abstract

The present disclosure relates to a measurement and compensation apparatus for the irradiation damage effect of a silicon photomultiplier (SiPM). A voltage adjustment module collects an anode voltage of an SiPM to obtain a dark current of the SiPM, and adjusts an output voltage of a power source module when a bias voltage across two ends of the SiPM deviates from a preset range of a target bias voltage, such that the bias voltage across the two ends of the SiPM is within the preset range of the target bias voltage, thereby realizing measurement of the dark current of the SiPM and compensation for the bias voltage across the two ends of the SiPM. A signal collection module is used to measure dark count noise of the SiPM, and a signal collection triggering threshold value of the signal collection module is adaptively adjusted according to the measured noise, such that the signal collection module performs signal collection when the amplitude of a signal transmitted from a first capacitor is greater than or equal to the signal collection triggering threshold value, thereby reducing the probability of false triggering by noise.

Abstract

Disclosed in the present invention are the synthesis of a lipid-coupled completely-degradable water-soluble polymer, and the use of the lipid-coupled completely-degradable water-soluble polymer in drug delivery. The structural formula is as shown in formula (I). The lipid-PPE molecule designed in the present invention has a hydrophobic lipid tail and a hydrophilic head, and can be used together with other existing lipid molecules to prepare RNA-encapsulated LNPs so as to efficiently complete the delivery of RNA. Repeating units of phosphoester bonds are introduced into the lipid-PPE molecule, so that the lipid-PPE molecule is easily degraded into small molecular monomers when entering organisms, thereby reducing inflammatory reactions. Liposomes or LNPs formed by combining degradable lipid-PPE and other lipid molecules can alleviate the antibody reaction and hepatotoxicity caused by traditional liposomes containing polyethylene glycol (PEG) after multiple injections.

Abstract

A micro spectrum chip based on units of random shapes, including. The micro spectrum chip include a CIS wafer and an optical modulation layer. The optical modulation layer includes several micro-nano structure units arranged on the surface of a photosensitive area of the CIS wafer. Each micro-nano structure unit includes a plurality of micro-nano structure arrays, and in each micro-nano structure unit, different micro-nano structure arrays are two-dimensional gratings composed of internal units of random shapes. In each micro-nano structure unit in this scheme, different micro-nano structure arrays have different shapes of internal units, and each group of micro-nano structure arrays have different modulation effects on lights with different wavelengths. The degree of freedom of “shape” is fully utilized to obtain a rich modulation effect on the incident light. A two-dimensional grating structure based on internal units of random shapes is utilized.

Abstract

Provided is a manufacturing method for graphite slider arrays in batches. In this method, a grain structures examination step is added to a process of manufacturing graphite slider arrays, and a subsequent etching step is controlled so that only one horizontal grain boundary exists inside the graphite mesas, and when cleaved, the sliders slide away on the only grain boundary. The slider arrays prepared by this method have uniform easy-slip surfaces and thickness with good consistency.
