Book ChapterDOI
Carbon nanotube-based matrices for tissue engineering
Gabriela S. Lorite,Olli Pitkänen,Melinda Mohl,Krisztian Kordas,Janne T. Koivisto,Minna Kellomäki,Monique Culturato Padilha Mendonça,Marcelo Bispo de Jesus +7 more
TL;DR: In this paper, a review of the use of carbon nanotubes for regenerative medicine is presented highlighting the advantages and disadvantages of carbon-nanotube-based matrices.
Journal ArticleDOI
Composites of ion-in-conjugation polysquaraine and SWCNTs for the detection of H2S and NH3 at ppb concentrations.
TL;DR: In this paper, the authors proposed a new type of resistive sensor device based on a composite of single-wall carbon nanotubes and an ion-in-conjugation polymer, poly(1,5-diaminonaphthalene-squaraine), capable of detecting H2S and NH3 in air even at room temperature with a theoretical concentration limit of ∼1 ppb and ∼7 ppb, respectively.
Journal ArticleDOI
Maskless direct growth of carbon nanotube micropatterns on metallic substrates
TL;DR: In this paper, the authors reported a simple process suitable for producing carbon nanotube micropatterns on steel alloys without the use of catalyst deposition, which is based on a pulsed laser beam induced surface microstructuring process, followed by a thermal chemical vapor deposition growth of nanotubes that emerge exclusively from the surface areas of the alloys previously exposed to the laser pulses.
Journal ArticleDOI
Flexible planar supercapacitors by straightforward filtration and laser processing steps
Olli Pitkänen,Toprak C. Eraslan,Dániel Sebők,Imre Szenti,Ákos Kukovecz,Robert Vajtai,Krisztian Kordas +6 more
TL;DR: A facile and scalable method of making flexible and mechanically robust planar supercapacitors with interdigital electrode structure made of commercial carbon nanomaterials and silver nanowires is presented.
Journal ArticleDOI
Aligned multi-walled carbon nanotube-embodied hydrogel via low magnetic field: A strategy for engineering aligned injectable scaffolds
Muthusamy Saranya,Janne T. Koivisto,Ana Caroline Nery Munoz Carvalho,Fernando Sato,Andrea Lassenberger,Lionel Porcar,Baleeswaraiah Muchharla,Saikat Talapatra,Birgitte Hjelmeland McDonagh,Lauriane Janssen,Olli Pitkänen,Minna Kellomäki,Krisztian Kordas,Gabriela S. Lorite +13 more
TL;DR: In this article , Carboxylated multi-walled carbon nanotubes (cMWCNT) are aligned into hydrogel via low magnetic field and the uniform dispersion and alignment of cMWcNT into the hydrogels are clearly demonstrated by small angle neutron scattering.
