A glass powder composite includes a first glass powder, and a second glass powder having a different solubility from that of the first glass powder depending on pH, wherein both the first glass powder and the second glass powder have ion sustained-release properties.

A glass, glass-ceramic, or ceramic bead is described, with an internal porous scaffold microstructure that is surrounded by an amorphous shield. The shield serves to protect the internal porous microstructure of the shield while increasing the overall strength of the porous microstructure and improve the flowability of the beads either by themselves or in devices such as biologically degradable putty that would be used in bone or soft tissue augmentation or regeneration. The open porosity present inside the bead will allow for enhanced degradability in-vivo as compared to solid particles or spheres and also promote the growth of tissues including but not limited to all types of bone, soft tissue, blood vessels, and nerves.

Provided is a magneto-optic element that enables easy size reduction of an optical isolator. A magneto-optic element is formed of two or more magnetic members joined together.

A light source device includes: a plurality of laser diodes that includes a first laser diode for emitting laser light of red color, a second laser diode for emitting laser light of green color, and a third laser diode for emitting laser light of blue color; a substrate directly or indirectly supporting the plurality of laser diodes; and a cap secured to the substrate and covering the plurality of laser diodes. The cap includes: a first glass portion configured to transmit the laser light that is emitted from the plurality of laser diodes, and a second glass portion. At least one of the first glass portion and the second glass portion comprises an alkaline glass region. The first glass portion and the second glass portion are bonded together via an electrically conductive layer that is in contact with the alkaline glass region. The first glass portion is bonded to the substrate.

Disclosed are biodegradable glass substrates that are useful as functional elements of solid-state devices. In particular, biodegradable glass substrates having a rapidly degradable glass and a slowly degradable glass provide a structural platform that completely dissolves following a desired operational lifetime of devices such as implanted electronic devices, implanted sensor devices, and optical fibers.

Compositions and methods for glass composites suitable for tissue augmentation, biomedical, and cosmetic applications are provided. The glass microsphere component of the composites are biologically inert, non-reactive and act as a nearly permanent tissue filler. One embodiment provides a tissue augmentation composite containing an effective amount of solid glass microspheres, hollow glass microspheres, porous wall hollow glass microspheres, or combinations thereof with a suitable biocompatible matrix to serve as a bulking agent when injected into a patient. The compositions can be used for soft or hard tissue augmentation as well as delivery of cargos on demand.
