Powder‐to‐Film Conversion of Nickel Single‐Atom Catalysts into Binder‐Free and Resistant Electrodes

Advanced Materials Interfaces, EarlyView.
A reproducible strategy is reported for fabricating standalone thin‐film electrodes composed of CNx‐supported Ni single‐atom catalysts. The resulting binder‐free electrodes exhibit robust stability, enhanced charge transfer, and superior electrochemical performance, offering scalable opportunities for applications in electrochemistry. ABSTRACT Although

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

Advanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.

Study on Lignite Humic Acids(III)On the Nitro Humic Acids.

Journal of the Fuel Society of Japan, 1955
亞炭フミン酸から諸種の條件によりニトロフミン酸の製造を行い, 各種條件で得られたニトロフミン酸の性質からフミン酸に対する硝酸の作用の概要を調べた。その結果フミン酸に対する硝酸の作用の最大のものは酸化反応であり, 加水分解反応もまた大きな作用であることを知つた。また酸化反応はフミン酸構成単位の脂肪族鎖を切断する方向に進行する。このことは稍々多量に製造したニトロフミン酸につきその示性式を求めることにより, さらに明白となつたまた。従来フミン酸と稍酸の反応で全く見落されていたシアン化水素並びにアンモニヤの生成を知り, その定量を行い, それらの生成がフミン酸のフェノール性に基くことを推定した。またフミン酸とジアゾメタンの反応によりO-メチル化以外に一部ジアゾメタンの附加が起ることを認め ...
