Summary: Electrospinning is the commonly used and promising method for producing nanofibers with small diameter, high specific surface area, and high porosity. In recent years, these nanofiber electrodes have been applied in solid oxide fuel cells (SOFCs), leading to significantly improved electrochemical performance due to their unique microstructure and electron and ion conduction properties. This paper provides a review of the research progress of electrospinning technology in the field of SOFCs, summarizing the effects of various processing parameters on fiber structure and introducing recent electrode preparations using electrospinning method.

Summary: This study introduces a novel hybrid faradaic structure to improve the performance of biomass-derived carbon-based supercapacitors (SCs). By carefully designing the organic-inorganic hybrid composition, nanostructures, porosity, surface area, and active redox reactions, pure lignin carbon nanofibers (LCNFs) incorporated with flower-like, multi-metal, and intrinsically capacitive nanoparticles were fabricated as flexible and binder-free electrodes for SCs. The experimental results demonstrate that the specific capacitance of the SCs can be significantly increased and the cycling stability can be improved by adding nanoparticles and using a mixed electrolyte.

Summary: The electrical properties of NiO thin films on different substrates were investigated, and it was found that the resistivity strongly depends on oxygen stoichiometry. Perfect stoichiometry leads to high resistivity, while off-stoichiometric films have lower resistivity, especially with oxygen-rich composition. Comparison of energy loss spectra rules out the presence of Ni3+ in NiO thin films, contradicting traditional hypotheses. Epitaxial NiO thin films on Al2O3 (0001) substrates exhibit higher resistivity than those on glass substrates, indicating microstructure dependence of electrical properties.

Summary: Semiconducting metal oxides (SMOs) used in gas sensors are affected by factors such as film thickness, grain size, and grain-grain junctions in the active device volume, complicating analysis and optimization of sensor response. Nanostructured devices with a single element offer a platform to understand the correlation between surface stoichiometry and sensor response. In this study, nanofabricated devices containing SnO2 and Sn3O4 nanobelts of different thicknesses were used to estimate their response to NO2 exposure, revealing differences in Debye length and sensor signals based on surface properties.

Summary: An investigation on the conductivity of individual carbon nanofibers (CNFs) and their networks reveals that the microscale CNF networks exhibit good electrical interconnections and a homogeneous current flow. The macroscopic conductivities are strongly correlated with the microscopic results. The presence of highly resistive surface fractions limits the conductivity of CNFs and their networks, and this limitation can be reduced by increasing the carbonization temperature. This study contributes to the understanding of the microstructual models of CNFs and their electrical properties, particularly electron percolation paths.

Summary: The surface properties and microstructure of graphene oxide (GO) membranes can be regulated to enhance nanofiltration performance. The surface hydrophilicity and zeta potential of GO membranes can be adjusted by alkaline treatment time, and the presence of tiny defects in GO sheets can increase the number of pores and decrease the length of water nanochannels. These adjustments enable GO membranes to exhibit fast and selective water permeation, demonstrating excellent nanofiltration performance.

Summary: Desalination of seawater is a main method for producing fresh water in many countries, but waste brine or concentrate rejects can have adverse effects on the environment due to high salinity. This study presents a simple process for reducing the salinity of concentrated brine and producing calcium and magnesium oxides, using an electrochemical system. By applying a DC potential, the system reduces the TDS of the brine solution and decreases cations and anions in the treated brine.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
