摘要:
The invention provides a method for producing carbon nanotubes, comprising spraying an oil onto a catalyst metal supported by at least one support selected from the group consisting of silica gel, alumina, magnesia, silica-alumina and zeolite which is placed in an atmosphere that has been controlled to a specific temperature, and an apparatus therefor. According to the invention, a large amount of carbon nanotubes can be synthesized from inexpensive raw materials by using a simple apparatus.

Disclosed are soluble diarylmethanofullerene derivatives that are effective as acceptors for organic thin-film solar batteries. They help to constitute effective organic thin-film solar batteries.
摘要:
A GaAs growth crystal comprises a Si substrate, an intermediate layer formed on the substrate and a GaAs layer grown on the intermediate layer. The intermediate layer includes constituent GaP/GaAsP and GaAsP/GaAs superlattice layers and additionally AlP and AlGaP thin films.
