Electrochemical characteristics of La0.8Sr0.2MnO3 (LSM)–scandia-stabilized zirconia (ScSZ) composite cathode

Overview of Approaches to Increase the Electrochemical Activity of Conventional Perovskite Air Electrodes

“…To increase the electrochemical activity of LSM air electrodes, their compositions with ionic conductors were applied, e.g., with solid electrolytes (YSZ [205,303,352,[372][373][374][375][376][377][378][379][380][381][382][383], YSZ with GDC10 [374], SSZ [149,[384][385][386][387][388][389][390], GDC10 [391], GDC [152,198], SDC [148,149,387,392,393], doped Bi 2 O 3 [151,[394][395][396][397][398][399], BaZr 0.85 Y 0.15 O 3 − δ (BZY15) [154], LWO56 [156], LSGM [400,401]), or MIEC materials (Co- [150,402] and Fe-based perovskites [403][404][405]). The optimu...…”

Revitalizing Oxygen Reduction Reactivity of Composite Oxide Electrodes via Electrochemically Deposited PrOx Nanocatalysts

“…The positions of the three electrodes and the distances between them were controlled to be constant. A VSP-300 (Biologic) was used to apply selected bias conditions of −1.5 V, (4,10,15) for PrO x (Figure S2, Supporting Information) and −1.5 V, (10,10,6) for (Pr,Ce)O x , under ambient temperature and pressure. During deposition, the CELD bath was continuously stirred at 300 rpm.…”

“…Solid oxide fuel cells (SOFCs) are promising next-generation energy conversion devices because of their high efficiency, fuel flexibility, and environmental friendliness. [1][2][3][4] The most commonly used air electrode material in SOFCs is lanthanum strontium manganite-yttria-stabilized zirconia (LSM-YSZ). [5,6] Although a variety of novel air electrode materials with superior oxygen reduction reaction (ORR) activities than that of LSM-YSZ have been developed, their common drawbacks, such as poor thermo-mechanical matching with the electrolyte because of differences in the thermal expansion coefficient (TEC), which restrict their practical applications.…”

Immunoaffinity biosensors for the detection of SARS-CoV-1 using screened Fv-antibodies from an autodisplayed Fv-antibody library

“…Impedance spectroscopy was carried out using a three-electrode system and commercial potentiostat from IVIUM Technologies (Eindhoven, Netherlands) ( Bong et al, 2019 ; Patel et al, 2021 ; Jeong et al, 2022 ; Park et al, 2022 ). A gold electrode was prepared by sputtering a titanium layer (10 nm) as an adhesive layer and a gold layer (200 nm) on an SiO 2 wafer as a working electrode.…”
