Latest Patents

Yvonne's latest patents include a method for chemical etching of emitter tips. This method involves forming a capillary tube for electrospray ionization (ESI) with a desired tip profile. The process includes providing a pre-finished capillary tube of substantially homogenous material, which is then wet-etched in an etchant for a specific duration. A protective fluid flows through the internal bore of the capillary tube during this etching process, allowing for precise control over the desired tip profile.

Another notable patent is the method and apparatus for fabricating microstructured optical fibers. This invention focuses on determining a preform geometry based on the desired optical properties of the fiber. The process involves tracking backwards in time the parameters of a set of conformal mappings that describe the fiber's cross-section. This innovative approach allows for the fabrication of optical fibers with complex geometries and multiple channels.
