Abstract: Lithium replenishing spaces are disposed on a current collection structure, such that the lithium replenishing spaces communicate with an active layer on one side; and the battery is replenished with lithium by using lithium replenishing agents in the lithium replenishing spaces to offset an irreversible lithium consumption in a cycle process, so as to increase the total capacity and the energy density of the battery. According to the present application, due to average weights MA of corresponding active materials in different distribution regions on the active layer, a sum V0 of internal volumes of lithium replenishing spaces corresponding to each of the distribution regions is controlled in a positively correlated manner based on a change in the average weights of the active materials in the different distribution regions.

After operably linking the mutant to a target gene, the expression efficiency of the target gene can be significantly improved, thereby effectively improving the yield and transformation rate of a target compound.

Abstract: A method for manufacturing fabric with flat screen and digital printed patterns includes: singeing, pretreatment, flat screen scraping sizing, drying, pattern printing, humidification, steaming treatment, washing, and non-ironing and soft setting. The pretreatment is a biological enzyme pretreatment process including: cloth feeding at 75° C., dipping, scouring and bleaching in a working fluid, heating to 90° C. for treatment of 30 minutes, draining, hot water washing and cold water washing. A shortened process flow can be realized, and the positioned sizing that uses a flat screen to scrape a sizing agent to a pattern position to be digital spray-printed on instead of traditional full-width sizing for sizing and printing, which greatly reduces the amount of sizing agent used, lowers production cost and reduces waste water pollution, and solves problem that the fabric is mottled caused by the application of sizing agent in areas without printed pattern due to full-width sizing.

Abstract: A fully integrated photonic coherent microwave generator includes an external laser cavity on a suitable material waveguide platform (e.g., LiNbO3) operationally integrated with a III-V gain element. Operational components include a tunable high-Q resonator (e.g., LiNbO3 microresonator) and one or more end mirrors to form an integrated semiconductor external-cavity laser. Operationally coupled electrical components enable coherent microwave and phase-locked laser comb outputs as follows. An optical detector converts the beating of generated laser-comb modes into microwaves with a fundamental frequency equal to the free-spectral range fR of the microresonator. The external laser cavity enables high-speed electro-optic modulation of laser modes directly inside the laser cavity. Phase locking of the lasing modes is accomplished via electro-optic modulation and electro-optic comb generation directly inside the laser cavity. Highly coherent microwaves are generated via phase-locked comb-like lasing modes.
