  • Patent number: 12060656
    Abstract: A capillary type multi-jet nozzle is provided for fabricating high throughput nanofibers by an electrospinning technique. The capillary type multi-jet nozzle includes a cap system with one or more pores and a crew system with a screw groove system. The cap system and the crew system are connected through a cap and crew system. The pores in the cap system are customized in count based on a requirement. The angle between the pores is reduced to make multiple non-interfering and non-hindering jets in less time. A TEFLONĀ® gasket is used for proper tightening and sealing of the cap system and screw system. The cap system includes knurling at an outer surface for grip. The capillary type multi-jet nozzle is made of a conducting material to with stand a high voltage and is fabricated using micro-machining process.

  • Publication number: 20230256412
    Abstract: The present invention relates to a natural plant extract based ethylene absorber and a process for preparing the same for inhibiting the ripening process of fruits, vegetables and flowers in cold storages, warehouses and household refrigerators. The ethylene absorber comprises of emulsifier, herbal oil extract, water and anti-oxidant agent combined together in a synergistic ratio. The process for preparing ethylene absorber comprises the steps of preparing solution by mixing distilled herbal oil extract and emulsifier in a beaker; stirring the solution to form a homogenous mixture; preparing a solution by mixing D.I water and anti-oxidant agent; stirring and combining the mixture and solution to form a new solution; dipping molecular sieves in the solution; adding the mixture into solution; soaking the material in the solution for next 60 minutes; and pulling out the material from solution and drying it in air oven.
