AI Article Synopsis

  • The study focuses on creating and testing modal liquid crystal lenses (MLCLs) that utilize a symmetrical electrode design with a conductive polymer called PEDOT-PSS.
  • The lenses show improved performance, including shorter focal lengths of up to 1cm, smaller apertures ranging from 1 to 5mm, and minimized optical distortions compared to previous models.
  • A key feature is the even distribution of conductivity across the PEDOT-PSS layers, allowing for lenses with short f-numbers and great depths of focus, resulting in enhanced optical quality.

Article Abstract

We describe the design, fabrication, and characterization of modal liquid crystal lenses (MLCLs) with a symmetrical electrode structure using a resistive composite polymer, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS). We achieved MLCLs with shorter focal lengths (up to 1cm), shorter apertures (1 to 5mm), and lower aberrations compared to other MLCLs. We demonstrate a very uniform conductivity distribution in the PEDOT-PSS layers over a wide resistivity range (100kOmega/sq-10MOmega/sq) combined with a symmetrical electrode structure, enabling us to manufacture MLCLs with short f-numbers, large depths of focus, and low aberrations.

Spatially selective imaging (SSI) involves sampling a group of pixels from different positions on an encoded object to display a decoded image. Here, SSI is achieved by using off-axis cylindrical Fresnel lens arrays to decode multiple images from an encoded print of structural color pixels. Each image is optically retrieved by separately placing different "keys" (arrays of lenses in different pseudorandom configurations) over the same encoded print, and then each image is digitally reconstructed for visualization.

Background: Nasopharyngeal carcinoma (NPC) is a malignant tumor with high prevalence in southern China. Aberrant DNA methylation, as a hallmark of cancer, is extensively present in NPC, the detection of which facilitates early diagnosis and prognostic improvement of NPC. Conventional methylation detection methods relying on bisulfite conversion have limitations such as time-consuming, complex processes and sample degradation; thus, a more rapid and efficient method is needed.

Aim: This study investigates the impact of sub-toxic cisplatin levels on nuclear and nucleolar abnormalities and chromosome instability in HeLa cells since our current knowledge of cisplatin effects on these parameters is based on studies with high concentrations of cisplatin.

Materials And Methods: HeLa cells were exposed to gradually increasing sub-toxic doses of cisplatin (0.01 to 0.

Objective: Genotoxicity assays include micronucleus test, comet assay, and malformed sperm head used to investigate the protective potential of quercetin and quercetin nanoparticles against imidacloprid-induced genotoxicity in Swiss albino mice.

Method: The ionic gelation procedure was used to synthesize the quercetin nanoparticles and characterized for their hydrodynamic diameter, zeta potential, SEM, TEM, FT-IR, and encapsulation efficiency. Total 48 mice were taken in eight groups with six animals in each group.

Unlabelled: Advances in DNA metabarcoding have greatly expanded our knowledge of microbial communities in recent years. Pipelines and parameters have been tested extensively for bacterial metabarcoding using the 16S rRNA gene and best practices are largely established. For fungal metabarcoding using the internal transcribed spacer (ITS) gene, however, only a few studies have considered how such pipelines and parameters can affect community prediction.
