The smut fungus obligately parasitizes and induces smut galls at the stem tips of host plants. Previous research identified a putative secreted protein, Ue943, which is required for the biotrophic phase of but not for the saprophytic phase. Here, we studied the role of Ue943 during the infection process.

Article Synopsis
  • Early diagnosis and treatment of bacterial infections are crucial, and photothermal therapy (PTT) offers an effective and minimally invasive sterilization method.
  • Researchers developed TiC-Au nanomaterials using an electrostatic self-assembly approach, achieving high photothermal conversion efficiency and superior performance in label-free bacterial detection through SERS.
  • TiC-Au nanobipyramids demonstrated excellent bactericidal rates against various bacteria and showed improved biocompatibility, making them promising candidates for both sensitive bacterial detection and effective sterilization.

Light field imaging (LFI) based on Liquid crystal microlens array (LC MLAs) are emerging as a significant area for 3D imaging technology in the field of upcoming Internet of things and artificial intelligence era. However, in scenes of LFI through conventional MLAs, such as biological imaging and medicine imaging, the quality of imaging reconstruction will be severely reduced due to the limited depth of field. Here, we are proposed a low-voltage driving LC MLAs with electrically tunable depth of field (DOF) for the LFI system.

In this paper, we present a new, to the best of our knowledge, structure of double pinhole/micro-lens array (DP/MLA) with two center-depth planes, used for improving the depth-of-field (DOF) of integral imaging (II), which can be fabricated by a combination of lithography and inkjet printing. The results show that a black circular groove array prepared by lithography can be used for micro-lens location and reduce the stray light for II. By controlling the parameters of the inkjet printing system, DP/MLA with high precision, high alignment, and good focusing ability can be achieved.

The low-cost large-scale fabrication of microlens arrays (MLAs) with precise alignment, great uniformity of focusing, and good converging performance are of great importance for integral imaging 3D display. In this work, a simple and effective method for large-scale polymer microlens arrays using screen printing has been successfully presented. The results show that the MLAs possess high-quality surface morphology and excellent optical performances.
