During the last decade a number of microcavity plasma devices have been developed. Examples are microhollow cathode (MHC) discharges and cathode boundary layer (CBL) discharges proposed by Schoenbach, capillary plasma electrode (CPE) discharges proposed by Kunhardt and Becker, and micro-structured electrode arrays (MSEs) introduced by Gericke and Penache. Arrays of microplasmas based on silicon...

We report remarkable photovoltaic effect in YBa2Cu3O6.96 (YBCO) ceramic between 50 and 300 K induced by blue-laser illumination, which is directly related to the superconductivity of YBCO and the YBCO-metallic electrode interface. There is a polarity reversal for the open circuit voltage Voc and short circuit current Isc when YBCO undergoes a transition from superconducting to resistive state. ...

In this work, we investigated the immobilization of methylene blue in a methyltrimethoxysilane sol-gel ceramic film on a glassy carbon electrode. Up to a certain saturation level, under our conditions, it was found that the methylene blue was tightly held and did not leach out into aqueous solutions, even with continuous immersion for up to 1 month. The electrochemical behavior of the immobiliz...

Recent worldwide interest in building a decentralized, hydrogen-based energy economy has refocused attention on the solid oxide fuel cell (SOFC) as a potential source of efficient, environmentally friendly, fuel-versatile electric power. Due to its high operating temperature, the SOFC offers several potential advantages over polymer-based fuel cells, including reversible electrode reactions, lo...

Abstract The Ce 0.8 Gd 0.2 O 2− δ (CGO) interlayer is commonly applied in solid oxide fuel cells (SOFCs) to prevent chemical reactions between the (La 1− x Sr )(Co y Fe )O 3− (LSCF) oxygen electrode and Y 2 3 -stabilized ZrO (YSZ) electrolyte. However, formation of YSZ–CGO solution with low ionic conductivity SrZrO (SZO) insulating phase still happens during cell production long-term operation,...

Protonic ceramic electrolysis cell (PCEC) is a promising technology for production of pure dry hydrogen due to the low operating temperature and high efficiency. One obstacles commercialization PCEC poor performance insufficient long-term durability oxygen electrode. In this study, we address above challenge by designing LaCoO3 (LC) catalyst infiltrated porous BaZr0.8Y0.2O3−δ (BZY20) backbone e...

This paper proposes the ELID (Electrolytic in Process Dressing) ultrasonic honing system, and conducts simulation for the solution acoustic coupling mechanism of electrolyte between the anion and cathode of ELID ultrasonic honing system. Meanwhile, a comparative experiment is carried out for the ultrasonic honing and ordinary honing. The simulation results show that there is no obvious increase...

Heterostructures of oxides have been widely investigated in optical, catalytic and electrochemical applications, because the heterostructured interfaces exhibit pronouncedly different transport, charge, and reactivity characteristics compared to the bulk of the oxides. Here we fabricated a three-dimensional (3D) heterostructured electrode with a concentration gradient shell. The concentration g...

Increasing densities of (electrode–electrolyte-pore) triple phase boundaries (TPBs) / reaction sites enhance performances solid oxide electrochemical reactors (SOERs) in both fuel cell (SOFC) and electrolyser (SOE) modes. Inkjet 3D printing is capable construction ceramic microstructures on support layers, enabling fabrication SOERs with enhanced active area to geometric ratios, thereby up-scal...
