“…Moreover, preparing the nanometer dimensional phase of TiNb 2 O 7 electrode and coating with conductive materials would be one of the most promising method to dramatically develop its energy storage advantages . As an example, nano‐TiNb 2 O 7 /carbon nanotubes electrode prepared by Guo et al can exhibit high reversible capacities of 346 mA h g −1 and 163 mA h g −1 at 0.1 and 30C rate, respectively . In addition, based on the low volume expansion and highly stable character derived from TiNb 2 O 7 , compositing with some anode materials with higher capacity can improve the energy density of overall LIBs.…”

Niobium‐based oxides including Nb2O5, TiNbxO2+2.5x compounds, M–Nb–O (M = Cr, Ga, Fe, Zr, Mg, etc.) family, etc., as the unique structural merit (e.g., quasi‐2D network for Li‐ion incorporation, open and stable Wadsley– Roth shear crystal structure), are of great interest for applications in energy storage systems such as Li/Na‐ion batteries and hybrid supercapacitors. Most of these Nb‐based oxides show high operating voltage (>1.0 V vs Li+/Li) that can suppress the formation of solid electrolyte interface film and lithium dendrites, ensuring the safety of working batteries. Outstanding rate capability is impressive, which can be derived from their fast intercalation pseudocapacitive kinetics. However, the intrinsic poor electrical conductivity hinders their energy storage applications. Various strategies including structure optimization, surface engineering, and carbon modification are effectively used to overcome the issues. This review provides a comprehensive summary on the latest progress of Nb‐based oxides for advanced electrochemical energy storage applications. Major impactful work is outlined, promising research directions, and various performance‐optimizing strategies, as well as the energy storage mechanisms investigated by combining theoretical calculations and various electrochemical characterization techniques. In addition, challenges and perspectives for future research and commercial applications are also presented.

In this study, grafted gelatin with oligoaniline (GelOA) was synthesized and then mixed with Poly (vinyl alcohol) (PVA). Several scaffolds with different ratio of PVA/GelOA were electrospun to fabricate electroactive scaffolds. GelOA was characterized using Fourier‐transform infrared spectroscopy (FTIR); moreover, nanofiber properties were evaluated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscope (SEM) analyses. Nanofibers diameter was decreased with aniline oligomer increment form 300 to 150 nm because of the hydrophobic nature of the aniline oligomer. Aniline oligomer electroactivity was studied using cyclic voltammetry, which exhibited two redox peaks at 0.4 and 0.6. Moreover, aniline oligomer enhancement resulted in melting point increasing from 220°C to 230°C because of the crystallinity increment. To assess the biocompatibility of nanofibers, cell viability and cell adhesion were tracked using mesenchymal stem cell (MSCs). It was revealed that the presence of aniline oligomer leads to enhancing the conductivity, thermal properties and lowering the degradation rate and drug release. Among of different scaffolds, sample with high content of GelOA shows better behavior in physical and biological properties. Accumulative drug releases under applied electrical field at 40 minutes showed that the drug release for stimulated condition is about 33% more than the unapplied electrical field one.

A co‐coagulation method combined with hot pressing technique is successfully applied to fabricate thermoplastic polyurethane (TPU) nanocomposites with different contents of carbon nanotubes (CNTs). Obviously, the mechanical and thermal properties of the nanocomposites are improved with increasing the CNT content. In addition, the existence of hydrogen bonding between CNTs and polymer matrix is demonstrated. Furthermore, the influences of impact parameters on solid particle erosion behavior are investigated systematically. The surface roughness and line roughness are also investigated to illustrate the mechanism of solid particle erosion. As elastic nanocomposites, the maximum and minimum erosion rate (ER) occur at 30° and 90°. The ER is relatively small when the impact velocity is at 10 m s−1, then is increased rapidly between 20 and 30 m s−1. As the size of impact particles increases to 300 µm, a rapid increase of ER occurs between 10 and 20 m s−1. All these results indicate CNTs improve the erosion resistance of TPU matrix.
