Abstract The scarcity of wettability, insufficient active sites, and low surface area graphite felt (GF) have long been suppressing the performance vanadium redox flow batteries (VRFBs). Herein, an ultra‐homogeneous multiple‐dimensioned defect, including nano‐scale etching atomic‐scale N, O co‐doping, was used to modify GF by molten salt system. NH 4 Cl KClO 3 were added simultaneously system obtain porous N/O co‐doped electrode (GF/ON), where ultra‐homogeneously etch, O‐functionalize...
Flexible sensing systems (FSSs) designed to measure plantar pressure can deliver instantaneous feedback on human movement and posture. This is crucial not only for preventing controlling diseases associated with abnormal pressures but also optimizing athletes' postures minimize injuries. The development of an optimal sensor hinges key metrics such as a wide range, high sensitivity, long-term stability. However, the effectiveness current flexible sensors impeded by numerous challenges,...
Gold(III) complexes supported by C-deprotonated fluorene-C^N^C ligands having high emission quantum yield up to 0.61 and long-lived emissive excited states are used as yellow emitters in color tunable PLEDs OLEDs. High EQEs of 13.16% 22.02% achieved the best PLED OLED, respectively. As a service our authors readers, this journal provides supporting information supplied authors. Such materials peer reviewed may be re-organized for online delivery, but not copy-edited or typeset. Technical...
Practical strongly phosphorescent platinum(<sc>II</sc>) green to white OLED emitters with bulky tetradentate O^N^C^N ligands.
[Pt(O(∧) N(∧) C(∧) N)]-type complexes are used as single emitters in solution-processed PLEDs with maximum EQEs of 15.55% for green and 12.73% white devices, which the highest values ever achieved based on Pt(ii) complexes.
Abstract Color‐tunable organic light‐emitting diodes (CT‐OLEDs) have a large color‐tuning range, high efficiency and operational stability at practical luminance, making them ideal for human‐machine interactive terminals of wearable biomedical devices. However, the device lifetime CT‐OLEDs is currently far from reaching requirements. To address this problem, tetradentate Pt(II) complex named tetra‐Pt‐dbf, which can emit efficiently in both monomer aggregation states, designed. This emitter...
2,5-Diphenyl-1,4-distyrylbenzene with all cis double bonds shows strong fluorescence in crystal, which is due to the chemical processes, c.a. isomerization and photocyclization being limited by lattice packing.
Large Na 0.5 K NbO 3 ( NKN ) piezoelectric single crystals were obtained by seed‐free solid‐state crystal growth method, which is a traditional sintering grain process, with LiBiO used as aid. The largest dimension of the was 11 mm × 9 mm. In addition to doping content, temperature, and time effect process systematically investigated considered from kinetics point view. With assistance Avrami analysis, parameters relevant determined. Laue diffraction transmission electron microscopy...
Highly concentrated electrolytes (HCEs) based on LiPF 6 in propylene carbonate (PC) have been examined as lithium-ion battery electrolytes. These HCEs lower ionic conductivities and higher viscosities than ethylene (EC) with 1.2 M , but they Li + ion transference numbers. Electrochemical cycling behaviour of LiNi 0.8 Co 0.015 Al 0.05 O 2 //graphite cells 3.2 PC resembles that EC-based electrolytes; the HCE impedance, which can be lowered by increasing test temperature. By employing Raman...
In this paper, graphite felts treated by square wave potential pulse were modified as electrode for vanadium redox flow battery (VRFB). X-ray photoelectron spectroscopy measurements indicated that the treatment felt can introduce oxygen-containing groups on surface. Moreover, also be etched to form nano-scale pores, without damage of mechanical property treatment. The formed pores and introduced enhance wettability electrolyte electrochemical kinetics V(II)/V(III) V(IV)/V(V) reactions. was...
Carbon nanosheets were synthesized by facile molten salt route using glucose as carbon source, and employed positive electrocatalyst for vanadium redox flow battery (VRFB). Two kinds of obtained at glucose/salt mass ratio 1:10 (CNS-10) 1:100 (CNS-100), respectively. Compared with CNS-10, CNS-100 graphene-like structure has crumpled shape large surface area. Electrochemical measurements verify that as-prepared exhibit good electrocatalytic properties to VO2+/VO2+ reaction, demonstrates the...
Abstract Coal is a porous medium. Oxygen molecules in the air penetrate through pores of coal and are adsorbed on surface. Low-temperature oxidation then occurs, by which spontaneous combustion promoted. Given this process, authors analysed physisorption characteristics O 2 pulverized from perspective nanopore structure. In study, five different kinds samples (two lignites, one bituminous coal, two anthracites) were selected, surface morphology, pore structure parameters oxygen capacity...
