Hydrolysis of polyethylene terephthalate (PET) into terephthalic acid (TPA) is one key approach for waste PET recycling. However, achieving an in-depth understanding in PET hydrolysis remains challenging. Herein, we employed machine learning (ML) methods to interpret the PET conversion with a dataset compiled, containing 942 data points and rich hydrolysis factors of PET-related information, heating type, acid/base catalyst (ABC), organic solvent (OS), co-solvent, phase transfer catalyst (PTC), and operational condition. A Neural Network model was found to be the best for predicting PET conversion, with a testing R2 and RMSE of 0.93 and 8.45%. The model-based interpretation suggested that operational conditions accounted for 45% of importance, followed by ABC (19%), OS (12%), and PTC (12%). Furthermore, hydrolysis time, temperature, and ABC concentration were identified as the top-three factors positively influencing PET conversion. This work facilitates the catalyst and process optimization for PET hydrolysis to promote the plastic circular economy. © 2025, The Authors. All rights reserved.

Recent advances in lithium-ion batteries have revealed the potential of Li-excess cation-disordered rock salt (DRX) cathodes, which expand the design space for cathode materials. The evidence of facile lattice substitution further provides a key strategy for activating redox reaction centers and enhancing the cycling performance of such materials. Here, the study explores how Sn-mediated local atomic ordering enhances reversible anionic redox activity in Li1.3Mn0.4Nb0.3O2 through the use of aberration-corrected scanning transmission electron microscopy, ex/in situ X-ray techniques, and theoretical calculation. The results demonstrate that Sn incorporation optimizes the local atomic structure, fostering the formation of rapid Li+ diffusion "elevator" pathways and short-range ordered structures, thereby enhancing the Li+ transport network. Additionally, quantitative analysis of the redox pathways and degree of participation for Mn and O during charge–discharge cycles reveals that the Sn-mediated electrode exhibits enhanced anionic O redox activity at high charging voltages, maintaining elevated activity throughout subsequent cycling. This sustained performance not only indicates increased redox capabilities but also suggests improved structural stability. By elucidating the complex interplay between composition, local structure, and performance, this study advances the understanding of DRX materials and underscores the potential of strategic elemental substitution for optimizing disordered cathode materials in next-generation energy storage systems. © 2025 Wiley-VCH GmbH.

The combined effect of hydrocolloid addition and microwave heating on the structural, physical and functional properties of cassava starch remains underexplored, despite individual studies on these modification methods. The dielectric properties, important for the microwave treatment of starch, have received little attention in recent studies. Cassava starch with and without addition of hydrocolloids (guar and xanthan gums) was modified by microwave heating for two different exposure times, and its structural, functional, and dielectric properties were studied. The dual modification enhanced the swelling power and oil holding capacity of the starch, reduced its gelatinization temperature, and did not alter its crystallinity. Notably, xanthan-modified starch microwaved for 6 min exhibited higher color variation (ΔE*) and increased granules agglomeration, while the microwave treatment alone roughened the surface of the starch granules. The mean diameters D[4,3] of starch increased with xanthan gum addition, microwave treatment (6 min), and their combination. The relative permittivity (ε’), loss factor (ε”) and penetration depth (D_p) were lower for samples modified by the combined method. Considering the type of hydrocolloid and the microwave exposure time, the combined modification significantly influenced the properties of starch, offering a promising approach to producing starch with enhanced functional properties. © 2024 KeAi Communications Co., Ltd

Stairmand-type cyclones are commonly used in industry to separate particles from gas streams by inertia, driven by the dual-vortex flow patterns. Here, new designs are proposed to eliminate the local non-ideal vortex patterns in a conventional Stairmand cyclone by inserting a flow divider at the entrance and adjusting the elbow exit orientation. A two-way coupled CFD–DPM approach is employed to analyze the performance of the modified cyclones. Simulation results show that the cyclone with the elbow exit oriented orthogonal to the entrance direction demonstrates better performance in terms of the cut size and sharpness. The installation of the flow divider reduces the vortex eccentricity by approximately 50%. The flow divider increases the gas velocity near the outer wall, allowing the quasi-free vortex in the cyclone’s outer region to become nearly fully developed at the entrance section through the reduction of the local secondary recirculation flows. The optimum flow divider outer wall thickness correlates to the wall shear stress distribution. With the optimum 2 mm outer wall thickness flow divider installed, the separation efficiency for 2 μm particles increases from 56.74% to 77.4%, and the cut size decreases from 1.87 μm to 1.23 μm.

Monitoring the level of melatonin (MEL), a neurohormone that plays a vital role in governing the body's circadian rhythms and sleep cycles, is critical due to its physiological importance and potential adverse side effects during overexposure. This research deals with the design and development of a novel electrochemical sensor by modifying a glassy carbon electrode (GCE) with a composite of poly(vinyl alcohol) (PVA), dextran (Dex), polypyrrole (PPy) and copper oxide particles (Cu2O) forming the PDPC composite. The synthesized composite was analyzed using both structural and morphological characterization methods. Additionally, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were conducted to examine electrochemical behaviour of the composite. Significantly, the dextran inclusion, which is a biocompatible polysaccharide, makes the composite more hydrophilic, film forming, and stable enhancing sensor properties, more importantly, electrochemically. The sensor showed high electrocatalytic activity towards MEL oxidation as studied using CV and DPV. For MEL oxidation, the oxidation peak was found at +0.6 V in phosphate buffer (pH 7.0) with an increase in current with respect to melatonin concentration. The sensor has a detection limit of 5.2 nM with a linear range of 10.0 nM to 850.0 μM, found to be better than most reported sensors. Analysis of real samples, such as human serum and urine, demonstrated the ability to selectively, stably, and reproducibly detect MEL. These data confirm the potential possibilities of using the sensor for clinical and point-of-care testing showing a significant development in polysaccharide-based electrochemical sensors. © 2025 Elsevier B.V.

Composite polymer electrolytes (CPEs) hold significant promise for solid-state batteries due to their ability to combine the benefits of inorganic fillers and polymer matrices. However, agglomeration of inorganic fillers can disrupt the formation of a percolation pathway, hindering lithium-ion transport. Here, we developed a stable, porous, and interconnected 3-dimentional LLTO (Li0.33La0.557TiO3) nanofiber scaffold and fabricate CPEs using in-situ crosslinked polyethylene glycol (xPEG). The resulting self-standing LLTOxPEG-65 achieved an ionic conductivity of 5.0 × 10−4 S/cm at 30 °C and a critical current density of 0.5 mA/cm2. A significantly lower activation energy (~0.2 eV) was observed in LLTOxPEG-65 compared to pristine xPEG (0.44 eV), indicating a transition of lithium-ion transport pathways from xPEG to the LLTO scaffold. However, increasing the xPEG content led to a decrease in ionic conductivity and a rise in activation energy, approaching that of pristine xPEG. DFT calculations revealed that Li+ transport in the [010] and [001] planes of LLTO predominantly takes place within the bulk rather than along the surface, while a concerted diffusion mechanism was observed in the [100] plane. Additionally, mesoscale-level computational analysis indicated that the high LLTO scaffold fraction (90 wt %) can ensure transport through the bulk of the fibers even with larger interfacial charge transfer resistance, around 1 Ω·cm2 between LLTO and xPEG. Presence of the highly percolated LLTO scaffold helps to promote efficient Li+ transport through the bulk of LLTO. © 2025, The Authors. All rights reserved.

Metallic materials are extensively utilized in biomedical implants due to their excellent strength and corrosion resistance. However, friction and wear-related issues remain important challenges in load-bearing implant applications. To address these concerns, multilayer Ti₃C₂T_x, Mo₂TiC₂T_x, and Mo₂Ti₂C₃T_x coatings were deposited onto stainless steel substrates in two distinct thickness ranges (lower: ∼100 to 150 nm;higher: ∼225 to 275 nm) and biotribologically tested under simulated body fluid lubrication conditions. Our results revealed that low coating thicknesses of Mo₂TiC₂T_x demonstrated the most favorable biotribological performance, reducing the wear rate by up to 33% and consistently lowering the coefficient of friction, with reductions of up to 56% compared to uncoated references, owing to their ability to form durable tribo-films under SBF lubrication. In contrast, Ti₃C₂T_x coatings increased friction and wear under considered conditions, while Mo₂Ti₂C₃T_x showed a moderate COF reduction but higher wear rates, particularly at higher coating thicknesses and loads. These findings emphasize the superior self-lubricating properties of Mo₂TiC₂T_x coatings, thus highlighting their potential to enhance the durability and longevity of load-bearing biomedical implants. © 2025 American chemical Society.
