“…Similar to that of the CuO standard compound illustrated in Figure 7e, the Cu Kedge of CMCs/Cu 2+ and U-ICMs/Cu 2+ at 8891 eV reflects a dominant presence of Cu 2+ ions. 59 This result was different from the finding from XPS observation for U-ICMs/Cu 2+ . XPS is a surface-sensitive technique.…”

In this work, we demonstrate a simple approach to synthesize urethane-linked imidazole-cellulose microcrystals (U-ICMs) for simultaneous adsorption and naked eye sensing of metal ions. The synthesis is based on surface chemical modification of cellulose microcrystals (CMCs) by 1,1carbonyldiimidazole and 1-(3-aminopropyl)imidazole, respectively. The adsorption and sensing of U-ICMs and CMCs in response to diverse metal ions

“…Recently, Nilmounget alhave used electrospun carbon/CuFe 2 O 4 composite nanofibers for electrochemical energy storage applications. Specific capacitances of carbon/CuFe 2 O 4 composite nanofibers in both Na 2 SO 4 and KOH showed higher than those of carbon nanofibers and CuFe 2 O 4 nanoparticles [36].…”

Nanofibers of cobalt manganese oxide (CoMn 2 O 4) were grown using an electrospun technique. Structural and microstructural characterizations confirm the formation of phase pure CoMn 2 O 4 with high porosity. The potential application of CoMn 2 O 4 nanofibers as an electrode material for energy storage device was studied using cyclic voltammetry and galvanostatic charge-discharge measurements. A specific capacitance of 121 F/g was observed with enhanced cyclic stability. Furthermore, an energy storage device was fabricated by sandwiching two electrodes separated by an ion transporting layer. The device showed a specific capacitance of 241 mF/cm 2 in 3M NaOH electrolyte. The effect of temperature on the charge storage properties of the device was also investigated for high temperature applications. The device showed about 75% improvement in the charge storage capacity when the temperature was increased from 10 to 70 o C.This research suggests that nanofibers of CoMn 2 O 4 could be used for fabrication of energy storage devices which could operate in a wide temperature range with improved efficiency.

“…The semicircle in the high-frequency region is attributed to the charge transfer resistance ( R ct ) at the electrode–electrolyte interface, and the inclined line in the low-frequency range (the Warburg impedance) corresponds to Li-ion diffusion in the electrode. 31 The NiO/TiO 2 electrode shows the lowest R ct and Warburg impedance among the testing electrodes. The low R ct is ascribed to the high number of electroactive sites due to the good dispersion of NiO nanosheets, while the tunneled TiO 2 nanofibers shorten the Li + diffusion pathways, reducing the Warburg impedance.…”

Hierarchical non-woven fabric NiO/TiO 2 film is prepared using a facile two-step synthesis by electrospinning and subsequent hydrothermal reaction to yield TiO 2 film decorated with NiO nanosheets. As an anode material for Li-ion batteries, the NiO/TiO 2 composite exhibits discharge and charge capacities of 1251.3 and 1284.3 mA h g À1 , with good cycling performance and rate capability.Characterization shows that the NiO nanosheets are distributed on the surface of the TiO 2 nanofibers.The total specific capacity of NiO/TiO 2 is higher than the sum of pure TiO 2 and NiO, indicating a positive synergistic effect of TiO 2 and NiO on the improvement of electrochemical performance. The results suggest that non-woven fabric NiO/TiO 2 film is a promising anode material for lithium ion batteries.
