Abstract: The pouch cell polymeric supercapacitor invention described here-in is a first of its kind supercapacitor utilizing a biodegradable and low cost conducting polymeric composite of polyaniline with or without molybdenum disulfide and with or without a pyrolyzed cellulose material such as pyrolyzed bacterial cellulose. The materials, their synthesis, component fabrication, assembly, and packaging materials and techniques are detailed and claimed for the pouch cell designed supercapacitor. State-of-the-art capacitive, energy, and life cycling performance are described and corroborated through rigorous electrochemical testing, outperforming marketed supercapacitors relying on activated carbons and rare earth minerals alone. Furthermore, the synthesis of the conducting polymer and bacterial cellulose composite as well as the electrolyte is incredibly facile and scalable with significantly lower materials and manufacturing costs when compared to that of commercial supercapacitors to date.

Abstract: Our invention is about the modification of the trunk injection syringe for the precise application of oxytetracycline for Huanglongbing (HLB) or the Citrus Greening Disease and different rates of curry leaf extract through trunk injection. The purpose of the adapter is to connect the syringe pump to flexible silicone tubing, which then connects to the threaded needle injector. The purpose of using the flexible silicone tubing is to provide the user with the possibility to hang the spring-loaded syringe from nearby branches since the mechanical contact between the threaded needle and the trunk is not strong enough to directly support the weight of the syringe filled with medicine. qPCR was performed at the end of the experiment to validate bactericide efficacy, and an increase in Ct value. Curry leaves extract-based bactericide formulation can emerge as an effective and sustainable method for citrus greening disease management, bolstering the global citrus industry.
