Abstract:

A new method is disclosed for the exfoliation of hexagonal boron nitride into mono- and few-layered nanosheets (or nanoplatelets, nanomesh, nanoribbons). The method does not necessarily require high temperature or vacuum, but uses commercially available h-BN powders (or those derived from these materials, bulk crystals) and only requires wet chemical processing. The method is facile, cost efficient, and scalable. The resultant exfoliated h-BN is dispersible in an organic solvent or water thus amenable for solution processing for unique microelectronic or composite applications.

International Classification:

H04M 1500

US Classification:

379136

Abstract:

A platform for connecting to a CCS7 network for supporting concurrently running CCS related applications. Copies of the SUs flowing through the network are sent to the platform where the FISUs, LSSUs and MSUs are filtered to provide the desired SU type for each of the applications. The MSUs are filtered by MSU category and MSU type within category into groups of MSUs of particular interest to the applications, respectively. Linked lists of filter elements associated with the respective linksets of the CCS7 network perform the filtering by comparing category and type fields to the MSU categories and types to form the groups. Filter change data received at a user interface is utilized to modify the filters.

Abstract:

A method allows for preparation of CNT nanocomposites having improved mechanical, electrical and thermal properties. Structured carbon nanotube forms such as sheet, yarn, and tape are modified with π-conjugated conductive polymers, including polyaniline (PANT), fabricated by in-situ polymerization. The PANI modified CNT nanocomposites are subsequently post-processed to improve mechanical properties by hot press and carbonization.

International Classification:

C23C 16/26

US Classification:

427596, 427140

Abstract:

A method for joining or repairing boron nitride nanotubes (BNNTs). In joining BNNTs, the nanotube structure is modified with amorphous carbon deposited by controlled electron beam irradiation to form well bonded hybrid a-C/BNNT structures. In repairing BNNTs, the damaged site of the nanotube structure is modified with amorphous carbon deposited by controlled electron beam irradiation to form well bonded hybrid a-C/BNNT structures at the damage site.
