Abrégé
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.
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.
An absorbable autoradiographic-contrast-enhancing hydrogel, preparation method therefor and application thereof, wherein the hydrogel is formed from a precursor component and a buffer component through polymerization and has a contrast-enhancing function stemming from inorganic nanoparticles generated by in-situ combination between anions in the buffer component and salt ions, wherein the precursor component includes a first component containinga star-shaped multi-arm polyethylene glycol terminated by an N-hydroxysuccinimide-activated ester or by an aldehyde and a second component containing a multi-amino compound, wherein the first and the second component are dissolved in the buffer component to form a first and a second hydrogel precursor component respectively, which will be mixed and delivered to a target site to form the hydrogel through an in-situ cross-linking reaction, or be mixed and after a first reaction stage undergo a second reaction stage at the target site to through an in-situ cross-linking.
