Abstract: A passive on-chip optical long-pass filter for removing residual pump photons at short wavelengths after nonlinear generation of photons. A thin layer (<100 nm) of amorphous or poly-crystalline silicon is deposited onto a section of a waveguide to absorb light with a wavelength shorter than the silicon bandgap wavelength of ˜1.1 ?m, while the nonlinearly generated light in longer wavelengths than the silicon bandgap wavelength propagates in the waveguide with a negligible absorption loss. The filter is applicable to attain an on-chip optical pump light rejection ratio exceeding 120 dB for nonlinear and quantum photonic chips. The filter is conceptually simple to design and can be fabricated by a CMOS process with potentially a high wafer-level scalability and manufacturability at a low cost. The filter can be realized in various integrated photonic platforms, including silicon carbide, silicon nitride, lithium niobate and aluminum nitride.

Abstract: Disclosed is a range hood, including: a case provided with a smoke inlet; and a fan provided inside the case. An air inlet area is formed between an air inlet of the fan and a side wall of the case, the air inlet area is provided with a spacer, and the spacer is configured to divide the air inlet area into at least two air inlet sub-areas. The air inlet sub-areas are located at different positions of the air inlet area. The airflow entering the case from the smoke inlet flows to the air inlet of the fan, and the airflow flows to the sub-air inlet area in different directions. The space blocks airflows in different directions, to prevent turbulence at the intersection of airflows in different directions.

Abstract: The disclosure discloses a method for preparing a multisubunit SCF E3 ligase with a fusion protein through in vitro reconstitution, and a use of the multisubunit SCF E3 ligase. The method for preparing a multisubunit SCF E3 ligase with a fusion protein through in vitro reconstitution disclosed by the disclsoure includes: subjecting an engineered SKP1-Cullin1-RBX1 fusion protein (referred to as eSCR) to a reaction with an F-box protein in a reaction system to obtain the multisubunit SCF E3 ligase, where the eSCR fusion protein has an amino acid sequence from position 10 to position 1062 of SEQ ID NO: 2. Experimental results show that different multisubunit SCF E3 ligases are successfully prepared with the eSCR fusion protein through in vitro reconstitution in the disclsoure; the reconstituted multisubunit E3 ligase has biological activity.
