  • Publication number: 20240421268
    Abstract: A quantum dot color filter (QDCF) and a display device are provided. The display device includes the QDCF and a lighting module that includes multiple lighting chips. The QDCF includes a substrate, a light-shielding planarization layer, and a pixel layer, and has multiple pixels that correspond to the lighting chips. Each pixel includes a light-transmissive region and a light-shielding region. The light-shielding planarization layer is disposed on the substrate, and is configured to define the light-shielding region of the pixel. The pixel layer is disposed on the light-shielding planarization layer, and includes multiple pixel units. The pixel unit overlaps with the light-transmissive region, and partially overlaps with the light-shielding region of the pixel. In the pixel, an area of each pixel unit is greater than an area of each lighting chip along an orthogonal projection direction.

  • Publication number: 20210047664
    Abstract: Fungal glucoamylases from Aspergillus fumigatus—expressed in Trichoderma reesei host cells (AfGATR) are provided. Trichoderma reesei host cells express AfGATRs at higher, or at least comparable, levels to natively expressed AfGA Aspergillus fumigatus. AfGATRs, including AfGA1TR and AfGA2TR, exhibit high activity at elevated temperatures and at low pH, so AfGATRs can be used efficiently in a process of saccharification in the presence of alpha-amylase, such as Aspergillus kawachii alpha-amylase (AkAA). AfGATRs advantageously catalyze starch saccharification to an oligosaccharide composition significantly enriched in DP1 (i.e., glucose) compared to the products of saccharification catalyzed by Aspergillus niger glucoamylase (AnGA) or native AfGA expressed in Aspergillus fumigatus. AfGATRs such as AfGA1TR, AfGA2TR or a variant thereof can be used at a lower dosage than AnGA and natively expressed AfGAs to produce comparable levels of glucose.

  • Patent number: 10472657
    Abstract: A method is disclosed for hydrolyzing an alpha-1,3 or alpha-1,6 glucosyl-glucose linkage in a saccharide (disaccharide or oligosaccharide). This method comprises contacting the saccharide with an alpha-glucosidase enzyme such as transglucosidase under suitable conditions, during which contacting step the enzyme hydrolyzes at least one alpha-1,3 or alpha-1,6 glucosyl-glucose linkage of the saccharide. This method is useful for reducing the amount of oligosaccharides in a filtrate isolated from a glucan synthesis reaction, for example.
