  • Publication number: 20210178010
    Abstract: A cost effective bacterial cellulose wound dressing includes a microbial-derived cellulose loaded with natural antibacterial and regenerative substances. This wound dressing is effective for the treatment of burns and chronic wounds. The dressing keeps the wound moist while absorbing exudates from the wound area. The dressings possess antibacterial qualities to protect the wound from infections and help the area to heal faster through the action of bioactive substances.

  • Publication number: 20210063311
    Abstract: A single unit, handheld field portable apparatus and method for analyzing Ochratoxin A (OTA) in rice quality monitoring, based on fluorescence signal output. Aliquots may be analyzed by adding at least one or more reagents to the sample aliquot that reacts selectively with an analyte contained therein. The reaction product, which is selective for the analyte of interest and proportional to its concentration, is measured with an appropriate detector. This enables simple and accurate testing of samples using time honored wet-chemical analysis method in microliter volume regimes while producing remarkably small volumes of waste. The device includes a multipurpose controller board for processing and analysis purpose, a camera which is integrated with the controller, a resistive touch liquid crystal display to view the results, a light emitting diode to emit the UV light, and a power bank. The device may operate using a touch display.

  • Publication number: 20200331961
    Abstract: A method is provided for extraction of fine silk fibroin powder from Bombyx mori silk cocoons. The conventional method of silk processing includes dissolution of the degummed silk fibers in some strong salt solutions followed by a dialysis step. The earlier reported strong salt solutions have either associated environment issues or lower dissolution ability for silk. However, the provided method includes degumming silk cocoons, drying and cutting the degummed silk fibers, mixing the fibers with an ionic liquid, stirring the mixture, regeneration of silk from the mixture with the help of an anti-solvent followed by centrifugation, drying the precipitated silk and finally obtaining a fine powder of silk.

  • Patent number: 10403495
    Abstract: According to exemplary embodiments, a method of synthesizing tin (Sn)-doped Zinc Sulfide (ZnS) nanostructures for electroluminescent white light source includes coating a substrate, including a silicon oxide layer, with Sn by vacuuming depositing Sn as catalyst nanostructures on the substrate, placing the substrate coated with Sn in a furnace, introducing a carrier flow gas into the furnace, adding a ZnS power to the furnace, growing ZnS nanostructures, and dissolving Sn in the growing ZnS nanostructures. The S vacancies are on a surface of the ZnS nanostructures. The ZnS nanostructures are grown on the substrate having a temperature in a range of 750° C. to 850° C.
