Embodiments in accordance with the present invention provide waveguide structures and methods of forming such structures where core and laterally adjacent cladding regions are defined. Some embodiments of the present invention provide waveguide structures where core regions are collectively surrounded by laterally adjacent cladding regions and cladding layers and methods of forming such structures.

Optical waveguides and methods thereof

A polymer comprising polycyclic repeating units having recurring ion conducting groups and optional crosslinkable groups is disclosed. The present invention provides the capability of tailoring polymers to impart unique properties to membranes fabricated from the polymers. Membranes comprising the polymers and methods for preparing the membranes and their use in ion conducting membranes, particularly in fuel cells, are also provided.

Polycyclic polymers containing pendant ion conducting moieties

A curing accelerator which is suitable for various curable resin compositions, an epoxy resin composition having excellent curability, storage stability and fluidity, and a semiconductor device having excellent solder cracking resistance and moisture resistance reliability are provided. The epoxy resin composition includes a compound (A) having two or more epoxy groups in one molecule, a compound (B) having two or more phenolic hydroxyl groups in one molecule, trisubstituted phosphoniophenolate or a salt thereof as a curing accelerator (C), and an inorganic filler (D).
