Amorphous phase-change memory alloy with no resistance drift Spontaneous structural relaxation is intrinsic to glassy materials due to their metastable nature. For phase-change materials, the resultant temporal change in electrical resistance seriously hampers neuromorphic computing applications. Here we report an ab-initio-calculation-informed design of amorphous phase-change materials composed of robust 'molecule-like' motifs, depriving the amorphous alloy of critical structural ingredients responsible for relaxation and, hence, resistance drift. We demonstrate amorphous CrTe<sub>3</sub> thin films that display practically no resistance drift at any working temperature from -200 °C to 165 °C, and highlight the multilevel encoding ability via a hybrid opto-electronic approach. We further reveal that the same no-drift behaviour holds for melt-quenched amorphous CrTe<sub>3</sub> in electronic devices. Moreover, the application potential of CrTe<sub>3</sub> is testified by its incorporation in a vehicle with an automatic path-tracking function. Our work provides an alternative route to achieve requisite properties for potential phase-change neuromorphic computing via the judicious design of disordered phase-change materials.

Electrochemical Commodity Polymer Up‐ and Re‐Cycling: Toward Sustainable and Circular Plastic Treatment The demand for commodity plastics reaches unprecedented dimensions. In contrast to the well-developed plethora of methods for polymer synthesis, sustainable strategies for the end-of-life management of plastics continue to be scarce. While mechanical re-cycling often results in downgraded materials, chemical re-cycling or up-cycling offers tremendous potential for an efficient and green approach, thereby addressing the precarious treatment of post-use plastics within a circular carbon economy. Recently, electrochemistry surfaced as a uniquely powerful tool for polymer up-cycling via polymer functionalization or degradation obtaining either novel polymers with valorized properties or high-value recycled small molecules, respectively. While discussing recent progress in that domain, future perspectives of electrochemical polymer modifications until January 2025 are outlined herein.

Vibronic coupling-driven symmetry breaking and solvation in the photoexcited dynamics of quadrupolar dyes Quadrupolar dyes, such as acceptor-donor-acceptor molecules, are highly relevant for applications in nonlinear optics and photovoltaics. They are also versatile models for exploring photoinduced charge-transfer dynamics. The interplay between electronic and vibronic couplings in these molecules may break excited-state symmetry, resulting in intramolecular charge separation and pronounced solvatochromism. Experimentally, distinguishing the roles of intramolecular vibronic coupling and solvent reorganization for the initial charge-transfer dynamics has been challenging so far. Here we investigate a prototypical quadrupolar dye in polar and non-polar solvents using ultrafast pump-probe and two-dimensional electronic spectroscopy. Our results reveal that vibronic couplings initiate excited-state symmetry breaking during the first ~50 fs of the photoinduced charge transfer, whereas solvent-induced charge localization sets in at later times. Quantum dynamics and electronic structure simulations support our experimental findings. Our results reveal the details of solvation dynamics in photoexcited molecules and suggest strategies for their manipulation through vibronic couplings.

Application of Artificial Neural Network (<scp>ANN</scp>) in Ultrasound‐Assisted Extraction of Bioactive Compounds ABSTRACT Artificial neural network (ANN) is regarded as a promising tool among the recent trends of modeling methodologies for the nonlinear mapping of multiple variables. In the case of the ultrasound‐assisted extraction (UAE) process, the majority of the response‐based predictive models are administered with nonlinear modeling approaches. Numerical models provide restricted extension and abilities to show such nonlinear prescient conditions. Due to this, ANN modeling gets considerable scope for effectively mapping the variables. In addition, the essential of no prior specific, in the event that there ought to emerge an event of fitting the data or information, make ANN the most popular and compelling one for modeling the extraction process. This paper provides the basics of principles and applications of ANNs in process modeling and optimization of different UAE‐based extraction perspectives. In addition, the prevalence of the UAE process in diverging from other extraction methods is highlighted. Further, the impact of various process factors like ultrasound intensity, exposure time, and temperature during the UAE interaction and their prescient modeling approaches for efficient controlling of the responses are detailed. Hence, this review would be useful for modeling and optimization of thermal and non‐thermal‐based extraction processes, which would assist the food processing industries to improve food quality.

Enhanced energy storage in relaxor (1-x)Bi0.5Na0.5TiO3-xBaZryTi1-yO3 thin films by morphotropic phase boundary engineering Perovskites at the crossover between ferroelectric and relaxor are often used to realize dielectric capacitors with high energy and power density and simultaneously good efficiency. Lead-free Bi<sub>0.5</sub>Na<sub>0.5</sub>TiO<sub>3</sub> is gaining importance in showing an alternative to lead-based devices. Here we show that (<i>1-x</i>)Bi<sub>0.5</sub>Na<sub>0.5</sub>TiO<sub>3</sub> - <i>x</i>BaZr <sub><i>y</i></sub> Ti <sub><i>1-y</i></sub> O<sub>3</sub> (best: 0.94Bi<sub>0.5</sub>Na<sub>0.5</sub>TiO<sub>3</sub> -0.06BaZr<sub>0.4</sub>Ti<sub>0.6</sub>O<sub>3</sub>) shows an increase of recoverable energy density and electric breakdown upon chemical substitution. In thin films derived from Chemical Solution Deposition, we observed that polarization peaks at the morphotropic phase boundary at <i>x</i> = 0.06. While Zr substitution results in reduced polarization, it enhances both efficiency and electric breakdown strength, ultimately doubling the recoverable energy density and the metallization interface by lowering surface roughness. Our dielectric capacitor shows <3% deviation of energy properties over 10<sup>6</sup> cycles. A virtual device model of a multilayer thin film capacitor (7.25 mJ recoverable energy) was used to compare its performance to already in use multilayer ceramic capacitors.

Efficient removal of Remazol Red dye from aqueous solution using magnetic nickel ferrite nanoparticles synthesized via aqueous reflux Rapid growth of the textile industry, along with the excessive use of water and dyes, has led to significant environmental concerns. This study introduces a straightforward, low-temperature aqueous reflux method for the fabrication of magnetic nickel ferrite (NiFe<sub>2</sub>O<sub>4</sub>) nanoparticles. The synthesized nanoparticles, characterized by X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and vibrating sample magnetometry (VSM), exhibited a cubic spinel structure, an average particle size of 23 ± 2.3 nm (range: 18-29.8 nm), and a magnetization of 56.96 ± 0.9 emu/g, enhancing their surface area and magnetic separability. These NiFe<sub>2</sub>O<sub>4</sub> nanoparticles achieved a 96.5 ± 0.4% removal efficiency of Remazol Red dye from aqueous solutions after 90 min, with an adsorption capacity (q<sub>max</sub>) of 169.5 ± 0.8 mg/g, as tested across pH 2-12, contact times of 10-120 min, and initial dye concentrations of 20-200 mg/L. Optimal removal occurred at pH 2, with a dye concentration of 20 mg/L and a 1 g/L dose, yielding 99 ± 0.5% efficiency, while adsorption decreased at high pH due to surface charge effects (PZC = 6.7). The results indicated that dye adsorption increased with decreasing pH and higher nickel ferrite dosage. Kinetic studies over 10-120 min followed pseudo-first-order (R<sup>2</sup> = 0.96), Boyd, and Weber-Morris models, while isotherms across 20-200 mg/L conformed to the Freundlich model (R<sup>2</sup> = 0.98), reflecting multilayer adsorption. These properties high crystallinity, nanoscale size, and strong magnetic responsiveness enhance the material's surface area, adsorption capacity, and ease of separation, contributing to its efficiency as an adsorbent. Reusability tests confirmed the stability of the nanoparticles and their consistent performance across multiple cycles. These results establish NiFe<sub>2</sub>O<sub>4</sub> as an economical, magnetically separable, and ecologically sustainable adsorbent for wastewater treatment purposes.

Mechanochemistry for the Synthesis of a Sustainable Phosphorus/Potassium Tannic Acid Flame-Retardant Additive and Its Application in Polypropylene Tannic acid (TA) is an abundant biobased aromatic compound that can form char under thermal degradation and fire conditions. In the present study, TA was chemically modified by grafting potassium phosphate groups using a two-step process, requiring neither heating nor organic solvents. Initially, TA was functionalized through ball-milling mechanochemistry in the presence of P2O5 to graft phosphoric acid, which was later converted to potassium phosphate salt by simple precipitation in water in the presence of KOH. The reaction yield was 87%. The resulting product, namely, TA-P-K, was used as a flame retardant (FR) in polypropylene (PP). At 30 wt %, TA-P-K was dispersed in PP by melt processing, resulting in a significant reduction in the peak heat release rate of 78% measured by the mass loss cone calorimeter test. Additionally, an intumescent residue was formed during combustion, which protected the material. In terms of flame-retardancy performance, the polymer composite took a “Good” label based on Flame-Retardancy Index (FRI), which seems promising in view of FR being fully biobased.
