  • Publication number: 20250229232
    Abstract: A method for preparing a functional membrane for recovering precious metal ions from oily wastewater is provided. The method includes: obtaining carbon nanotubes functionalized by polyacrylic acid (CNTs-PAA) by grafting acrylic acid onto a surface of carbon nanotubes (CNTs) via graft polymerization; obtaining carbon nanotubes modified by acyl hydrazine functional groups (CNTs-PAH) by reacting adipic dihydrazide (ADH) with carboxyl functional groups of the CNTs-PAA; preparing single-layer MXene nanosheets using Ti3AlC2 powder; and preparing a CNTs-PAH/MXene composite membrane by vacuum filtration based on the CNTs-PAH and the single-layer Mxene nanosheets.

  • Patent number: 11506869
    Abstract: A miniature imaging lens for close-range imaging includes: a first lens group, an aperture, and a second lens group sequentially arranged in a direction from the object side to the image side of an optical axis; the first lens group and the second lens group have positive focal power, an object-side clear aperture of the first lens group is larger than an image-side clear aperture of the first lens group, and an object-side clear aperture of the second lens group is less than an image-side clear aperture of the second lens group, and specific process parameters are provided. A sandwich structure lens configuration composed of a first lens group, an aperture and a second lens group can obtain a high close-range imaging effect under the condition of miniaturization, and can effectively reduce aberrations of close-range imaging, especially distortion and chromatic aberration.

  • Publication number: 20220014655
    Abstract: A portable micro imaging device includes a lens and a lens body. The portable micro imaging device is detachably connected with a portable imaging device having a camera and an illuminator. The lens body is made of a transparent or semi-transparent solid material. An outer surface of a front surface of the lens body is partially provided with an independent specular reflection layer or diffuse reflection layer to cover the illuminator, and the specular reflection layer or the diffuse reflection layer is made of an opaque material. A closed annular light-transmission ring is formed between the specular reflection layer or the diffuse reflection layer and an outer periphery of the front surface of the lens body. An opening size of a mounting hole of the lens body in the front surface of the lens body is larger than a size of the lens.
