ABSTRACT Electrochromic energy storage devices (EESDs) have emerged as innovative technologies in and smart materials, generating considerable interest for numerous applications, such wearables, windows, color‐changing sunglasses. EESDs consist of two primary categories: electrochromic supercapacitors (ESCs) batteries (ECBs). These are particularly appreciated their multifunctional features, which allow them to alter color response different charge densities. The performance efficiency rely on three essential components: (I) the current collector or substrate (cc/substrate), serves conductive base device; (II) electrolyte, supports ion movement improves overall electrochemical performance; (III) materials (ECMs), responsible changes functions. Careful selection optimization these components crucial enhancing devices' efficiency, stability, lifespan. Advanced flexible stretchable shown significant potential. Their natural flexibility facilitates seamless incorporation into curved surfaces diverse shapes, making especially suitable wearable other cutting‐edge applications. However, this also brings challenges, including concerns related delamination, material dissociation, degradation over time. A thorough investigation is progressing conversion systems. Grasping vital creating sustainable solutions improving capabilities.

Maghemite (γ-Fe2O3) nanoparticles have attracted considerable interest for electronic applications due to their tunable electrical properties. Doping strategies offer an effective way optimize resistive behavior use in devices. In this study, cobalt (Co) was incorporated into γ-Fe2O3 enhance its X-ray diffraction (XRD) confirmed the retention of cubic P4332 phase, with Co doping inducing subtle lattice distortions ionic substitution. Scanning and transmission electron microscopy (SEM/TEM) revealed morphological changes, where incorporation influenced particle shape size distribution. Electrical conductivity analysis demonstrated a decrease both AC DC increase content, indicating enhanced behavior. The activation energy suggests reduction charge carrier mobility, leading higher resistivity. Impedance spectroscopy further increased real imaginary impedance values, reinforcing role suppressing transport. These results position cobalt-doped maghemite as promising material devices, such resistors negative temperature coefficient (NTC) thermistors, controlled stable are essential.

Enhancing the stability of polymer gels under harsh conditions is vital for improving enhanced oil recovery (EOR) applications. This study introduces a novel gel synthesized using MgO-HPAM nanocomposite and zirconium sulfate crosslinker (CL). The demonstrates exceptional durability, capable maintaining its properties high temperature salinity, addressing long-standing challenges in EOR. research involved several key experiments. Initial tests revealed that MgO does not influence gelation time; this controlled by CL concentrations. significantly improved storage modulus, with increases 72.47% 84.52% at 250 500 ppm MgO, respectively. Syneresis studies showed after 50 days, retained 88% their weight, unlike nanocomposite-free which lost 75%. In core flooding experiments, demonstrated higher injection pressure reduced permeability compared to nano-free gels. SEM imaging confirmed nanoparticle agglomeration sand face, enhancing gel's barrier properties. Over days 90 °C 2000 psi, reductions were observed 58%, 98.1%, 97.9% across samples. These findings underscore potential advancing EOR techniques.

Abstract This study investigates the environmentally friendly synthesis of Fe₃O₄ nanoparticles using basil leaf extract as a sustainable precursor. The resulting basil–Fe₃O₄ were extensively characterized through Fourier-Transform infrared, UV–Vis, scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, and VSM to verify their structural, morphological, magnetic properties. Optical analysis showed prominent absorption peak at 263 nm band gap energy 3.87 eV, suggesting its potential for photocatalytic applications. catalytic performance basil–Fe 3 O 4 was tested in 2-benzylidene malononitrile derivatives under microwave irradiation, achieving up 98% purity crystalline form across 12 examples involving aromatic heteroaromatic aldehydes with malononitrile. catalyst exhibited excellent reusability minimal loss activity over several cycles, highlighting greener more chemical processes. Additionally, evaluated degradation Congo red dye, an impressive 97% efficiency UV irradiation. Kinetic indicated high regression coefficient significant reaction rate constant, confirming superior activity. limit detection quantification determined be 32.8 99.16 mg·L −1 , respectively, affirming method’s sensitivity reliability detecting dye. Remarkably, even small amount (5%) enabled efficient low exposure, showcasing large-scale wastewater treatment. dual functionality both organic environmental remediation highlights promise advancements green chemistry treatment
