“…In addition, the present case includes the time series analysis (TSA) model to predict and forecast the chronoamperometric stability beyond 800 s for the optimized ZC-0.1/CH 3 –Cu-BTC NC-based photoanode. TSA is an important statistical technique that can be used for the modeling, prediction, and forecasting of electronic devices. , At the outset, the present work has used the Dickey-Fuller (ADF) test to check the stationarity in the time series. , The value of the ADF test along with the p -value is found to be −9.1556 (0.01), and it implies that the present time series of the ZC-0.1/CH 3 –Cu-BTC NC-based photoanode is stationary. To model, predict, and forecast the chronoamperometric stability of the ZC-0.1/CH 3 –Cu-BTC NC-based photoanode, we used the Holt-Winters exponential smoothing (HWES) technique.…”

This research investigates the photoelectrochemical (PEC) water splitting capabilities of Cu-based metal−organic framework (MOF)-sensitized one-dimensional (1D) metal oxide nanostructures, specifically zinc oxide (ZnO) nanorod (NR)/ multiwalled carbon nanotube (MWCNT) nanocomposites (ZC NCs). This study involves the synthesis of ZnO NRs as well as ZC NCs with varying content of MWCNTs (from 0.05 to 0.25 wt %) via the sol−gel technique, followed by a comprehensive analysis of their structural, optical, and surface properties. The incorporation of MWCNTs with ZnO revealed the enhanced optical and surface characteristics and high concentration of oxygen vacancies in ZC NCs as evidenced by electron spin resonance (ESR) analysis, contributing to improved PEC performance. Thereafter, binder-free thin films of the synthesized materials were deposited using the doctor-blade technique, and then, PEC water splitting performance was assessed through various electrochemical techniques. Herein, the PEC performance of ZC-0.1 NCs (with 0.1 wt % MWCNTs) was 4.5 times superior to that of bare ZnO NRs. Subsequently, the optimized ZC-0.1 NCs were further sensitized with CH 3 −Cu-BTC MOFs, forming ternary ZC-0.1/CH 3 −Cu-BTC NCs. For these ternary NCs, an impressive current density was observed (2.57 mA/cm 2 ), nearly 9 times greater than that of pristine ZnO NRs (1.23 V) vs the reversible hydrogen electrode (RHE) and almost double that of ZC-0.1 NCs. Furthermore, the designed photoanode is stable over time, which was predicted and forecasted through the time series analysis (TSA) model. The higher PEC performance for ternary NCs was justified through surface topography, morphological, and contact angle studies to analyze the surface nature and its hydrophilicity. Hence, the present work demonstrates the systematic roadmap for a PEC water splitting study using valuable insights for the design and optimization of nanostructured metal oxides, photoactive organic moieties, and their composites.

In recent years, the emergence of memory devices, especially resistive random-access memories (RRAM), has been a front-runner in many technological applications. This is due to its high-speed operation, structural simplicity, low power consumption, scalability potential, and high-density memory storage features. To develop an efficient and miniaturized memory device based on the resistive switching effect, it is necessary to study the range of materials and their fabrication techniques. In this review article, we have summarized the diverse organic and inorganic materials and their resistive switching performance. Furthermore, we reviewed some potential materials for next-generation resistive switching devices. In the resistive switching device fabrication front, numerous physical, chemical, and biological-based synthesis techniques were briefly reviewed. The influence of preparative parameters was also discussed. Finally, the current status and future directions of this field are discussed. The present review article provides important details of the resistive switching effect, promising organic and inorganic materials, and various fabrication techniques to improve the device's performance for memory applications.

“…[67][68][69][70] Various methods have been used for the preparation of perovskite-type compounds, including the traditional solution method, magnetron sputtering, sol-gel process, [71][72][73] hydrothermal synthesis, 74,75 and high-energy ball milling. 76 Previously, a memristor based on zinc titanium oxide (ZnTiO 3 ) was prepared using solution combustion synthesis described by Akhilesh et al 77 In this work, a device with an Al/ZnTiO 3 /FTO structure exhibited excellent performances with endurance cycles of 10 3 and a retention property up to 10 4 s. Besides, Blagoev et al fabricated LSMO and LSMO/YBCO polycrystalline films on an r-cut Al 2 O 3 substrate by magnetron sputtering, 78 which could exhibit ferromagnetic behavior at room temperature. In the same year, Xie et al also prepared LSMO thin films by DC magnetron sputtering and studied the effect of annealing on memristive properties.…”
