Fully Additive Vertical Organic Electrochemical Transistors on Renewable and Compostable Substrates Enable Ultrasensitive Bioelectronics

Advanced Functional Materials, EarlyView.
Fully additive vertical organic electrochemical transistors (vOECTs) with channel‐length of 226 nm on a 50 µm compostable substrate achieve >106 current modulation and ∼36 mS transconductance. Ion‐selective integration enables 1.1 mA dec−1 sensitivity and 36 µm detection limit, highlighting a scalable platform for sustainable electronics and ...

Reversible mechano-electrochemical writing of metallic nanostructures with the tip of an atomic force microscope

Beilstein Journal of Nanotechnology, 2012
We recently introduced a method that allows the controlled deposition of nanoscale metallic patterns at defined locations using the tip of an atomic force microscope (AFM) as a “mechano-electrochemical pen”, locally activating a passivated substrate ...

Chemical State Detection and Charge Transfer in Complex Oxide Heterostructures via In Situ Auger Electron Spectroscopy

Advanced Functional Materials, EarlyView.
In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...

Electrochemical Deposition of Collagen

The Journal of the Society of Chemical Industry, Japan, 1970
著者らは繊維性蛋白質の各種成形物を収得するため電着法を開発している。本報ではコラーゲンフィブブリルの電気化学的性質と電着におよぼす各種因子の影響を検討した。コラーゲン・フィブリルの移動度は pH, 温度, 粘性係数, フィブリル含量, フィブリルの長さなどの影響を受けることがわかった。また電着におよぼす通電量, pH, 電流密度, フィブリル含量などの影響について検討した結果, コラーゲンの電着量は通電量に比例して増加するが, コラーゲン電着の電流効率は電流密度の影響を受けないことがわかった。しかしこの電流効率は電解液のフィブリル含量によって変り, すなわち 0.7% 以下の濃度では電流効率はフィブリル含量に比例して良くなることが明らかとなった。
