Abstract Redox-active organic molecules have drawn extensive interests in redox flow batteries (RFBs) as promising active materials, but employing them nonaqueous systems is far limited terms of useable capacity and cycling stability. Here we introduce azobenzene-based compounds new materials to realize high-performance RFBs with long life high capacity. It capable achieve a stable low decay 0.014% per cycle 0.16% day over 1000 cycles. The under concentration 1 M also realized, delivering...
Abstract Aqueous redox flow batteries (RFBs) are promising alternatives for large‐scale energy storage. However, new organic redox‐active molecules with good chemical stability and high solubility still desired high‐performance aqueous RFBs due to their low crossover capability abundance. We report azobenzene‐based hydrophilic groups as active materials by utilizing the reversible activity of azo groups. By rationally tailoring molecular structure azobenzene, is favorably improved from near...
In this work, Au nanoparticle (AuNP) arrays on shape memory polyurethane (SMPU) substrates serve as flexible materials for tunable localized surface plasmon resonance (LSPR). AuNP prepared by diblock copolymer self-assembly are transferred from rigid silicon wafers onto SMPU with ultrasonic treatment rather than peeling off directly. The resultant array films have excellent mechanical properties and stable thermodynamic properties. LSPR arising is increased negative bending substrates,...
Magnetic properties and electronic structures of graphene with Cl, S, P adsorption have been investigated using ab initio calculations. The Cl leads to Fermi level shifting valence band, which results in metallic graphene. A band gap 0.6 eV emerges a S-absorbed graphene, leading the semiconducting unpaired electrons absorbed atom are polarized thus exhibit magnetic moment 0.86μB, while no has observed after S adsorption. This demonstrates that conductive behavior can be modified via...
Ferroelectric BiFeO${}_{3}$ is otherwise promising for photovoltaic applications, but its large band gap limits efficient absorption of sunlight. The authors show that, through structural engineering, ferroelectric (BiCrO${}_{3}$)${}_{m}$/(BiFeO${}_{3}$)${}_{n}$ superlattices can exhibit unexpectedly low gaps that approach the ideal Shockley-Queisser value. These results indicate superlattice structuring be an effective strategy designing oxide semiconductors with fundamental much smaller...
Hard carbon is considered as the most commercially applicable anode for sodium-ion batteries. Lignin has characteristics of sustainable, low cost, high content (>60%) and abundant oxygen functional groups, which expected to be used a promising candidate precursor low-cost hard carbons. The structure electrochemical performances carbons could regulated by adjusting carbonization temperature. microstructure performance LDHC are highly dependent on Increasing temperature reduce specific surface...
Novel approach has been constructed for preparing the amphiphilic star copolymer pH/reduction stimuli-responsive cross-linked micelles (SCMs) as a smart drug delivery system well-controlled anti-tumor doxorubicin (DOX) release. The SCMs had low CMC value of 5.3 mg/L. blank and DOX-loaded both spherical shape with sizes around 100–180 nm. In addition, good stability well pH/reduction-sensitivity were determined by dynamic light scattering (DLS) well. owned release DOX in bloodstream normal...
Soft carbon is a promising anode material for potassium-ion batteries due to its favorable properties such as low cost, high conductivity, stable capacity, and potential platform. Polyvinyl chloride, white pollutant, soft precursor that can be carbonized at varying temperatures produce carbons with controllable defect crystal structures. This work investigates the effect of carbonization temperature on crystalline structures obtained carbons. In situ Raman spectroscopy was used elucidate...
