In this paper, we synthesized a novel binuclear Ir complex [(Dfppy)(4)Ir-2(ecbtpd)] with a bis beta-diketone substituted carbazole derivative as the auxiliary ligand and 2-(2-fluoro-4-methylphenyl) pyridine as the main ligand. The thermal stability, UV-vis absorption spectra, photoluminescence spectra, phosphorescent lifetime, electrochemistry, and luminescent mechanism of this Ir complex were investigated as well as the device fabricated in phosphorescent PLEDs through solution-process technique. The devices show yellow emissions with maximum current efficiency and maximum external quantum efficiency of 23.67 cd/A and 8.44%, respectively.

Microscale or nanoscale patterns with specific structures on sapphire substrate can effectively reduce the dislocation defects of gallium nitride (GaN) material and improve the quality of gallium nitride crystal during the epitaxy growth of GaN-based light-emitting diodes, thus improving the internal quantum efficiency of LED luminescence. Numbers of methods have been used to fabricated patterned sapphire substrate. But most methods remain on the micron scale. In this work, the nickel annealing technique was introduced to fabricate a novel sapphire substrate, Hierarchical Patterned Sapphire Substrate (HPSS), which has typical characteristics of nano sapphire pillars on a Micro-Patterned Sapphire Substrate (MPSS) used for GaN-based Light-Emitting Diodes (LEDs). Nano-pillars with an average feature size of about 110 nm and feature surface density of ⪆2.339×109 cm-2 were obtained on commercial MPSS through this method. This nickel annealing technique provides an extremely simple, cost-effective and universal method to fabricate hierarchical patterns with two-inch wafer-scale. What’s more, the substrates can be not only sapphire but also extended to silicon, quartz and other heat-resisting materials which are widely used in photoelectric devices and micro/nanofabrication, making it a promising method to fabricate patterned substrate for industrial applications.

Metal-based materials, like stainless steel (SS), have been proved to be a promising bioelectrodes and current collectors for microbial fuel cells (MFCs). The microbial electrocatalysis performance of these metal electrodes could be greatly enhanced by surface modification, e.g. reactive bonding nanocarbon. Herein, we report the enhancement of microbial electrocatalysis of metal-based bioanode by thermal oxidation of the nanocarbon conductive filler, carbon black (CB). Oxidation of CB by thermal treatment at 400 and 500 degrees C in air (denoted as CB-400, CB-500) only led to slightly increase of oxygen content, from 4.34% in pristine CB to 5.54% in CB-500, while by thermal treatment at 110 degrees C in nitric (denoted as CB-N) led to a great increase of oxygen content to 9.58%. Microbial electrocatalysis results revealed that though the CB-N had the highest oxygen content, the bioanode it modified did not bring improvement of microbial electrocatalytic performance; while the bioanode modified by CB-500 led to an approximately 20% current density increase comparing to that modified by pristine CB. The quinone oxygen-containing functional groups of the CB-500 filler resulted by thermal treatment were found to be crucial for the enhancement of microbial electrocatalysis of the bioanode, because they could act as mediators to enhance the mediated electron transfer. This study provided an effective strategy for enhancing the microbial electrocatalysis of CB/SS composite bioanode by the appropriate oxidation of CB.

In this study, we report a facile method of anchoring Mn3O4 nanoparticles on the surface of wood-derived porous carbon via electrodeposition to enhance the specific capacitance and cycling performance of electrodes for supercapacitors. Owing to the synergistic effect of the natural tubular porous structures of wood-derived porous carbon and the high theoretical specific capacitance of Mn3O4, wood-derived porous carbon-Mn3O4 composites (WPC-Mn3O4) deliver a high specific capacitance (315 F g(-1) at the current density of 1 A g(-1)) and an outstanding cycling stability (91% of maximum capacitance after 10,000 cycles at 10 A g(-1)) in 1 M Na2SO4 electrolyte. Furthermore, the WPC-Mn3O4 and activated carbon (AC) assembled asymmetric supercapacitor (ASC) WPC-Mn3O4//AC delivers a high energy density of 34.85 Wh kg(-1) at 700.0 W kg(-1), demonstrating a high applicability in practical energy storage devices. The resultant WPC-Mn3O4 composites with excellent electrochemical properties are expected to be used as a potential cathode material for the development of high-performance supercapacitors.
