  • Patent number: 12178193
    Abstract: A method for mass rearing of Telenomus remus includes the following steps: (1) establishing a Telenomus remus population of a Corcyra cephalonica strain; (2) collecting Corcyra cephalonica eggs laid by Corcyra cephalonica on the day, and fixing the Corcyra cephalonica eggs on a sticker; (3) inoculating female Telenomus remus of the Corcyra cephalonica strain in the step (1) into the Corcyra cephalonica eggs in the step (2); and (4) after 24 h to 48 h of a parasitism, taking parasitic Corcyra cephalonica eggs out, and feeding the parasitic Corcyra cephalonica eggs under the following conditions: a temperature: 26±1° C., a relative humidity: 65±5%, and a photoperiod: L:D=14:10, where long axes of the Corcyra cephalonica eggs in the step (2) have a length of 0.48 mm to 0.60 mm. The method of the present disclosure has great significance for the long-term control of pests of the Noctuidae family.

  • Publication number: 20180175297
    Abstract: A method of fabricating a thin film transistor, the method includes applying a first ink containing metallic particles to a first screen mask, and using the first screen mask to deposit the first ink to form a source electrode and a drain electrode on a substrate bearing a layer of carbon nanotubes (CNT). The method includes applying a second ink containing a dielectric material to a second screen mask, and using the second screen mask to deposit the second ink to form a layer of the dielectric material on the layer of CNT between the source electrode and the drain electrode. The method includes applying a third ink containing metallic particles to a third screen mask, and using the third screen mask to deposit the first ink to form a metallic gate electrode on the layer of the dielectric material to form the thin film transistor.

  • Patent number: 9878000
    Abstract: Disclosed is a mucoadhesive nanoparticle delivery system for delivering an immunosuppressant, such as cyclosporine A, to a mucosal site for treatment of a disease or condition involving inflammation or excess immune activity. The system comprises nanoparticles formed from a plurality of linear amphiphilic block copolymers, each having a hydrophobic block comprising polylactide (PLA) and a hydrophilic block comprising dextran. The nanoparticles are surface-functionalized with a mucosal targeting moiety, such as a phenylboronic acid derivative, for targeted delivery and enhanced retention at the mucosal site. Pharmaceutical compositions, methods, and uses thereof comprising the mucoadhesive nanoparticle delivery system are disclosed. The compositions can be administered in an effective amount for treating the disease or condition while substantially preserving or restoring the function and/or integrity of the mucosal lining.
