Abstract:
Novel uses of diamondoid-containing materials in the field of microelectronics are disclosed. Embodiments include, but are not limited to, thermally conductive films in integrated circuit packaging, low-k dielectric layers in integrated circuit multilevel interconnects, thermally conductive adhesive films, thermally conductive films in thermoelectric cooling devices, passivation films for integrated circuit devices (ICs), and field emission cathodes. The diamondoids employed in the present invention may be selected from lower diamondoids, as well as the newly provided higher diamondoids, including substituted and unsubstituted diamondoids. The higher diamondoids include tetramantane, pentamantane, hexamantane, heptamantane, octamantane, nonamantane, decamantane, and undecamantane. The diamondoid-containing material may be fabricated as a diamondoid-containing polymer, a diamondoid-containing sintered ceramic, a diamondoid ceramic composite, a CVD diamondoid film, a self-assembled diamondoid film, and a diamondoid-fullerene composite.
Abstract:
Disclosed are processes for the recovery and purification of higher diamondoids from a hydrocarbonaceous feedstock. Specifically disclosed is a multi-step recovery process for obtaining diamondoid compositions enhanced in tetramantane components and other higher diamondoid components. Also disclosed are compositions comprising at least about 10 weight percent of non-ionized tetramantane components and other higher diamondoid components and at least about 0.5 weight percent of non-ionized pentamantane components and other higher diamondoid components based on the total weight of diamondoid components present.
Abstract:
Friedelin is a natural compound with promising proprieties. On its own or with chemical modification it is possible to introduce relevant biological activities, e. g., anti-cancer, anti-aging and agrochemical. Its availability in significant amounts has been a major drawback on its regular use and in the pursuit of different applications. Cork and cork-derived materials (e. g., black condensate) are the most relevant sources of Friedelin in nature (up to 10% in concentration). The present invention reports straightforward procedures to extract and purify Friedelin from cork and cork-derived materials (e. g., black condensate). It uses solvent extraction and (re)crystallization techniques easy to scale up to an industrial level, with a low solvent and low time consumption, high yields, up to 2.9%, and high purity degrees, up to 96%.
