Electric Field-Assisted Structuring of Glass
TechnologyThis invention describes an electric field assisted glass structuring process that allows for post-melt processing and forming or surface/local structuring. It provides a means for glass components to be softened and changed to a desired texture at relatively low temperatures or even after glass forming, such as in a composite configurati...

An in-crown/in-denture electrical system and the process of electrical stimulation with a through-hole stimulation channel and an inductive link
TechnologyIn-Crown / In-Denture Electrical SystemSystem and process of electrical stimulation to residual nerves to enable the recovery of missing sensory feedbackDue to the aging population, many adults are at risk of losing nerve function in their teeth due to endodontic procedures such as root canals, dental implants, and dentures. Animal and hu...

A Solid State Process for Fabricating Single Crystals from Glass
Technology Glass can be directly converted into a single crystal, avoiding the gaseous or liquid phase. Sb2S3 single crystals were grown in 16SbI3–84Sb2S3 glass as an example of this approach. As confirmed in this first unambiguous demonstration of an all-solid-state glass to crystal transformation, extraneous nucleation can be avoided durin...

A Method to Obtain Vertical Near-field Interaction in Scattering Type Near-field Optical Microscopy
SUMMARY While a conventional microscope (~250 nm optical resolution) is not suitable for the nano-world structures imaging (one millionth of a millimeter), Scanning near-field optical microscopy (SNOM) is capable of a super-resolution (~10 nm) imaging and surface topology, providing a spectroscopic characterization of nano-structures in a routine f...

A New Antenna-feedback Scheme to Achieve Emission in a Narrow Beam from Metal-cavity Semiconductor Lasers
SUMMARY The invention is based on a distributed antenna-coupling (feedback) scheme and specially designed distributed feedback (DFB) metallic cavity grating. By ensuring the predesigned phase condition, the mode traveling inside the waveguide is coupled/phase-locked to the mode traveling outside on the top metal, hence establishing a standing-wave...

Synthesis of a Large Pore Periodic Mesoporous Slicas with Crystalline Channel Walls at Pressures <5 GPa
SUMMARYPeriodic mesoporous silica materials were first discovered by Mobil Oil in 1992 for use in petroleum cracking applications. It was envisaged that these larger pore materials would allow for a more effective processing of the heavier hydrocarbon molecules than microporous zeolite catalysts. However, this did not happen because the mesoporous ...
