Formation of Gold Nanorod Dimers and their Activity for Surface-Enhanced Raman Scattering

Shuichiro Hakoda、Mikiko KISU、Kanjiro Torigoe 等 7 位作者2013-01-01Journal of the Japan Society of Colour Material

Side-by-side connected gold nanorod dimers were formed by ligand substitution of hexadecyltrimethylammonium bromide (C16TAB) bilayer with 1-hexylamine. The addition of 1-hexylamine caused a gradual aggregation of gold nanorods, which was verified from blue shift of the longitudinal localized surface plasmon resonance…

The effect of drying method on the morphology of III-V microtubes

Bochang Li、Qi Wang、Eryang Wang 等 9 位作者2013-01-01Asia Communications and Photonics Conference 2013

Through the adoption of critical point drying, doubly curved regions (DCR) observed on the III-V microtubes vanished. This process verified that the DCR does not result from the natural release of the residual strain energy.

CORROSION RATE OF STEEL BARS IN REINFORCED CONCRETE UNDER OXIDIZING ENVIRONMENT AND REDUCING ENVIRONMENT

Kouhei ASASE、Satoshi Kaneko、Hiroshi Seki2013-01-01Journal of Japan Society of Civil Engineers Ser E2 (Materials and Concrete Structures)

本研究は密閉された地下空間に建設されるRC構造物中の鉄筋の腐食挙動を解明することを目的としたものである．建設直後の構造物内は酸素が存在する酸化性環境となるが，長期的には酸素濃度が極めて低い還元性環境へ移行すると想定される．本研究ではこの一連の環境を実験的に模擬し，種々の電気化学的手法を用いてコンクリート中鉄筋の腐食を検討した結果，次の様な結論を得た． (1)腐食速度は，温度20℃・酸化性環境では0.001～0.011μA/cm2であり，温度50℃・還元性環境へ移行後は0.013～0.056μA/cm2であった．これらの値は電気化学的手法で評価した既報と同等あるいはそれ以下であった． (2)分極の精度に影響を与える要因は，特に電位掃…

We prepared oxyhydrides of the perovskite ATiO3 （A＝Ba, Sr, Ca） via low-temperature reduction using CaH2. The obtained oxyhydrides are stable against temperature as well as A-site substitution, and the hydride species are exchangeable with outer hydrogen gas, implying the hydride diffusion through the lattice. The exch…
