Title: Spectral resolution enhancement device
Inventor: LIU CHEN
IPC: G01J3/18
Filed: 2019-11-21
Abstract: A spectral resolution enhancement device comprises: a preliminary dispersion unit (1), a two-grating angular dispersion amplification unit (2), and a detection unit (3). The preliminary dispersion unit (1) is used to receive a collimated incident light beam, and enable light having different wavelengths in the incident light beam to be emitted at different angles. The two-grating angular dispersion amplification unit (2) is used to separately diffract light having different wavelengths and emitted from the preliminary dispersion unit (1) multiple times, such that angular dispersion of the various wavelengths is enhanced, and emergent angle deviations between different wavelengths of light are increased. The detection unit (3) is used to detect light having different wavelengths and emitted from the two-grating angular dispersion amplification unit (2). Since the emergent angle deviations for different wavelengths of light are increased, the detection unit (3) has increased resolution for different wavelengths. The spectral resolution enhancement device amplifies angular dispersion to improve spectral resolution, and has a small structure, thereby facilitating integration with various spectrometers.

Filed: 2020-04-08
Abstract: Bandwidth selection for communication of random access information. A wireless communication device may use one or more resource block (RB) sets for transmitting random access information on a shared radio frequency (RF) spectrum such as an unlicensed band. In some examples, the maximum transmit power for the wireless communication device may be restricted (e.g., by a regulation). Thus, the wireless communication device may, in some circumstances (e.g., when the wireless communication device is at or near a cell edge), transmit the random access information via multiple RB sets instead of a single RB set in an attempt to access a BS. To this end, the BS may allocate multiple RB sets for a random access transmission by the wireless communication device and monitor each of these RB sets for random access information.

Abstract: Disclosed is a method for preparing a biomass-based conductive hydrogel by 3D printing. Firstly, a cellulose-based macromonomer, a rosin-based monomer, an acrylic acid monomer, and an initiator are mixed in a certain proportion, stirred, and dissolved at 25-70°C. Then, diisocyanate in an amount of 5-10 wt% of a total mass of the monomers is added to the mixed solution and mixed uniformly to prepare a 3D printing photosensitive resin solution. An SLA light-curing 3D printer is used to print a hydrogel precursor 1 with a complex shape. Next, the hydrogel precursor 1 is heated to obtain a hydrogel precursor 2 with a dual-curing network. Finally, the obtained hydrogel precursor 2 is swelled in a 1-15 wt% alkaline solution at 5-60°C for 0.1-10 hours to obtain the biomass-based conductive hydrogel. The invention can be used to prepare a biomass-based hydrogel with a complex shape, excellent electrical conductivity, and high mechanical strength. The invention can further broaden the application fields of biomass resources.
