Abstract This study reports the realization of electrostatic fractional-order capacitors (FOCs) by usage graphene oxide (GO) loaded polyvinylidene fluoride (PVDF) composites. The Solution-mixing and drop-casting methods were employed to prepare composite. dispersed GO within polymer functions as a micro-capacitor micro-resistor electrical network, emulating behaviour FOCs. demonstrated fractional capacitance response graphene-percolated composites having frequency bandwidth 500 Hz–300 kHz....
Flexible, free-standing polyvinyl alcohol (PVA)-zirconia (mean particle size ∼24 nm) nanocomposite films have been synthesized and their performance as a potential next-generation resistive switching device material has assessed in this report. The switch from high state (HRS) to low (LRS) at the SET LRS HRS RESET within voltage window of 5 V. origination trap-assisted SET/RESET potentials experimentally validated by analyzing experimental data invoking various theoretical models....
Nanoplate to pseudocubic-shaped hematite (α-Fe2O3) nanoparticles along with the gradual engravement of tetrahedral Fe3+ has been synthesized by controlling precursor (FeCl3 ·6H2O) concentration from 0.005 M (A1) 0.2 (A4). The role surfactant polyvinylpyrrolidone on preferential plane ([110] [012]) growth and highly energetic phase (increases 2.7 times for A4 than A1) nucleation over surface elucidated HRTEM images, XPS, Raman spectroscopy. This morphology variation facilitate Fe–Fe...
Environmental pollution caused by millions of waste plastics not only is depleting our natural resources but also one the key factors for climate change and globally growing. Moreover, developing carbon-free energy production crucial renewable remains challenging. Hence, development triboelectric nanogenerators (TENGs) based on plastic a promising solution that can address both issues simultaneously. In this study, we demonstrate three types TENGs layered VS2 (plastic-VS2), SnS2...

In study, redox generated near ∼-0.42 V limit around ∼2.09 μM bottom...
The semiconducting behavior of two-dimensional (2D) metal nanostructures has recently attracted much interest for their possible applications in optoelectronics and others. In particular, tuning the bandgap such can open up a new avenue fabricating functional nano-devices. present article, we report synthesis 2D metallic Zn nanosheets at room temperature using ball mill, which is capable producing large-scale materials single run. Initially, nanoplates were formed milling octahedral-shaped...
Hematite (α-Fe2O3) nanoparticle has been synthesized by hydrothermal method and incorporated into Polyvinyl Alcohol (PVA) for preparing a flexible composite film. The dielectric constant, loss tangent, Cole-Cole impedance ac conductivity variation in frequency (50 Hz≤f≤1MHz) voltage (± 20 V) of current density (J) resistivity temperature range 303 to 383K have studied the nanocomposite shows prominent relaxation peak. spectroscopy reveals that there is grain boundary region this follows CBH...
