Journal ArticleDOI
Optical Activity of Heteroaromatic Conjugated Polymer Films Prepared by Asymmetric Electrochemical Polymerization in Cholesteric Liquid Crystals: Structural Function for Chiral Induction
TL;DR: In this article, the authors electrochemically polymerized various achiral heteroaromatic monomers in left-handed helical cholesteric liquid crystal (CLC) media, and the resulting conjugated polymer films exhibited both the first negative and second positive Cotton effects near their absorption maxima.
Journal ArticleDOI
Formation of crystalline Si nanodots in SiO2 films by electron irradiation
TL;DR: In this article, the energy threshold for the crystallization of amorphous Si was determined to be 150.2 kV, and the key factors for the transformation from SiO2 to crystalline Si were determined.
Journal ArticleDOI
Microstructures and rheological properties of tilapia fish-scale collagen hydrogels with aligned fibrils fabricated under magnetic fields.
Song Chen,Noriyuki Hirota,Mitsuhiro Okuda,Masaki Takeguchi,Hisatoshi Kobayashi,Nobutaka Hanagata,Toshiyuki Ikoma,Toshiyuki Ikoma +7 more
TL;DR: Differential scanning calorimetry measurements indicated that collagen hydrogels with and without magnetic treatment had the same denaturation temperature, 48°C, while EDC crosslinking increased theDenaturation temperature to 62°C.
Journal ArticleDOI
Near room temperature chemical vapor deposition of graphene with diluted methane and molten gallium catalyst.
Jun-ichi Fujita,Takaki Hiyama,Ayaka Hirukawa,Takahiro Kondo,Junji Nakamura,Shin Ichi Ito,Ryosuke Araki,Yoshikazu Ito,Masaki Takeguchi,Woei Wu Pai +9 more
TL;DR: A great reduction of graphene CVD temperature is reported, down to 50 °C on sapphire and 100C on polycarbonate, by using dilute methane as the source and molten gallium (Ga) as catalysts, and a demonstrated low-temperature graphene nuclei transfer protocol.
Journal ArticleDOI
Fabrication of magnetic nanostructures using electron beam induced chemical vapour deposition
TL;DR: In this article, fine focused electron beam induced chemical vapour deposition with iron carbonyl gas, Fe(CO)5, was carried out at room temperature to fabricate desired shape nanostructures such as dots, rods and rings.
