Toward mesoporous 1D structures: Expanding interlayer spaces in cup-stacked Carbon nanotubes

open access: yesCarbon Trends
Tailoring the pore structure in materials is a key to achieving efficient ion/molecular transportation. The interlayer space in graphitic materials can be expanded via the oxidation–exfoliation process. However, since the intercalation-mediated oxidation

Synthesis of Nickel-Encapsulated Carbon Nanocapsules and Cup-Stacked-Type Carbon Nanotubes via Nickel-Doped Fullerene Nanowhiskers [PDF]

open access: yesJournal of Nanotechnology, 2012
Nickel- (Ni) doped C60 nanowhiskers (NWs) were synthesized by a liquid-liquid interfacial precipitation method using a C60-saturated toluene solution and isopropanol with Ni nitrate hexahydrate Ni(NO3)2·6H2O.

Mechanical properties of rubber composites with cup-stacked carbon nanotubes

open access: yesTanso, 2009
Cup-stacked carbon nanotubes (Cup-CNTs) consist of truncated conical graphene layers which exhibit open edges on the tube outer surface. Therefore, when used as filler, Cup-CNTs are expected to have many contact points with the matrix. Acrylonitrile butadiene rubber (NBR) composites containing Cup-CNTs were prepared by mixing the chloroform solutions ...

Luminescence of Cup-Stacked Carbon Nanotubes and Its Application to Microchip Electrophoresis

open access: yesBunseki Kagaku, 2009
従来,マイクロチップ電気泳動でレーザー励起蛍光検出を用いて高感度検出を試みる際に試料の蛍光標識を行う.しかし,蛍光標識は煩雑な操作,標識に伴う分離能の低下及び低濃度試料の蛍光誘導体化効率の低下という問題を有しており,蛍光標識を不要とする高感度検出法の開発が望まれている.著者らは遠心操作によりカップ積層型カーボンナノチューブ(cup stacked carbon nanotubes,CSCNTs)が蛍光を発することを見いだし,泳動液へのCSCNTsの添加によりDNAのマイクロチップ電気泳動分離及び非標識(間接蛍光)検出に成功した.CSCNTsは蛍光を有することに加えて ...

Stacked-Cup Carbon Nanotube Flexible Paper Based on Soy Lecithin and Natural Rubber

open access: yesNanomaterials, 2019
Stacked-cup carbon nanotubes (SCCNTs) are generally referred to as carbon nanofibers (CNFs). SCCNTs are much less expensive to fabricate and are regarded as good polymer modifiers suitable for large-scale production.
