Abstract:
... For the first time, we present exploratory investigations on the performance of thermally evaporated Sb₂S₃ thin film photoanodes for solar-assisted water-splitting applications. With a band gap of 1.72 eV, a 250 nm thick Sb₂S₃ photoanode showed a saturation photocurrent density of ∼600 μA cm–² measured at 1.0 V reversible hydrogen electrode (RHE) in 0.1 M Na₂SO₄ under 1-sun illumination, with an o ...

Abstract:
... Three-dimensional heterostructured NiCo₂O₄@MnMoO₄ nanocolumn arrays (NCAs) on Ni foam were first fabricated through an improved two-step hydrothermal process associated with a successive annealing treatment. The hybrid NiCo₂O₄@MnMoO₄ electrode exhibited remarkable pseudocapacitor property with high initial mass specific capacitance of 1705.3 F g–¹ at 5 mA cm–², and retained 92.6% after 5000 cycles ...

3. Hierarchical MnO2 Spheres Decorated by Carbon-Coated Cobalt Nanobeads: Low-Cost and High-Performance Electrode Materials for Supercapacitors

Author:
Zhi, Jian; Reiser, Oliver; Huang, Fuqiang

Subject:
capacitance; carbon; cobalt; electrical conductivity; electrochemistry; electrodes; electrolytes; manganese dioxide
Abstract:
... MnO₂ is a promising electrode material for supercapacitors, because it exhibits high theoretical specific capacitance (1380 F g⁻¹) for electrical charge while also being inexpensive and environmentally benign. However, owing to its low electrical conductivity, the intrinsic pseudocapacity of MnO₂ is not fully utilized. In this work, hierarchically structured spheres composed of MnO₂ nanoplatelets ...

Subject:
copper; electrodes; electronics; energy; irradiation; microstructure; nanoparticles; wavelengths; white light
Abstract:
... In this work, an intensive plasmonic flash light sintering technique was developed by using a band-pass light filter matching the plasmonic wavelength of the copper nanoparticles. The sintering characteristics, such as resistivity and microstructure, of the copper nanoink films were studied as a function of the range of the wavelength employed in the flash white light sintering. The flash white li ...

Abstract:
... Cholesterol is a major modifiable risk factor in cardiovascular disease and can be effectively managed by a combination of medication and monitoring. There continues to be a need for new point-of-care diagnostics to measure lipid panels, including total cholesterol. Enzyme assays based on the generation of hydrogen peroxide have been very effective in this regard. This work demonstrates the applic ...

Abstract:
... The elemental N emerged uniformly in graphdiyne (GDY) after heat treatment under NH₃ atmosphere to form N-doping GDY. The interplanar N–GDY distance decreased slightly, which may be ascribed to the smaller atom radius of N than C. Compared with GDY, the introduction of N atoms in N-GDY created numerous heteroatomic defects and active sites, thus achieving enhanced electrochemical properties, inclu ...

In this work, we fabricated an electrochemical biosensor for the rapid detection of Dam methyltransferase activity based on the exonuclease III (Exo III) assisted isothermal amplification cycle. First, double stranded DNA (ds-DNA) containing ...
