The electrochemical noise method (ENM) has previously been employed to monitor the corrosion of steel reinforcement in concrete. development solid-state Ag/AgCl-based probes and dedicated monitoring technology (ProCoMeter) now offers a wider range ENM configurations. present study involves laboratory investigation three mortar samples containing bars varying additions chloride, with view future...

近年、溶融亜鉛めっき鋼および耐候性鋼は、コンクリートの補強筋としての適用性が検討されている。これら鋼材の表層に形成された亜鉛めっき膜や保護性錆には大気中での高耐食性が知られているが、鋼材のコンクリート中での電気化学的挙動に対する表層皮膜の影響には未解明な点も多い。本報では、各鋼材のコンクリート中での防食機構・腐食進行プロセスを電荷挙動に基づき把握するため、電気化学ノイズ（EN）の測定や統計・ウェーブレット解析に基づき腐食速度や腐食形態を評価した。鋼材表面の腐食状態およびEN解析の結果から、溶融亜鉛めっき鋼および耐候性鋼は、同一条件下で磨き丸鋼に比べ腐食進展が遅く、耐食性が期待できることがわかった。

the applications of electrochemical machining are increasing because of increasing requests of industries for materials with high strengh and high hardness. regular ecm uses a tool with spicified profile shape that is similar to final shape of workpiece. in this reasearch a nozzle that delivers electrolyte to the machining gap is used for machining cylinderical workpieces. by moving the electro...

UNLABELLED Rapid detection of bacterial pathogens is critical toward judicious management of infectious diseases. Herein, we demonstrate an in situ electrokinetic stringency control approach for a self-assembled monolayer-based electrochemical biosensor toward urinary tract infection diagnosis. The in situ electrokinetic stringency control technique generates Joule heating induced temperature r...

Electronic detection of the binding event between biotinylated bovine serum albumen (BSA) and streptavidin is demonstrated with the chemoreceptive neuron MOS (CnuMOS) device. Differing from the ion-sensitive field-effect transistors (ISFET), CnuMOS, with the potential of the extended floating gate determined by both the sensing and control gates in a neuromorphic style, can provide protein dete...
