This study introduces a novel quantitative framework utilizing cumulative entropy generation and a validated PET Lifespan Index to define the precise thermodynamic and physical boundaries of mechanical PET recycling, thereby establishing quantifiable limits for material circularity across multiple life cycles.
This study presents a magnetically recoverable Fe₂O₃/ZSM-5 composite catalyst synthesized via excessive impregnation that achieves 95% degradation of Rhodamine B through a heterogeneous Fenton-like mechanism driven by hydroxyl radicals, offering a sustainable solution for dye wastewater treatment with efficient catalyst recovery and minimized secondary pollution.
This study demonstrates that corncob biochar modified with zero-valent iron using grape seed extract as a green reducing agent achieves a high Cr(VI) removal efficiency of 96.14% through a mechanism involving electrostatic attraction, coordination, and redox reactions, while maintaining good stability over multiple reuse cycles.
This study demonstrates that increasing the synthesis temperature of polypyrrole–polyvinyl alcohol nanocomposites systematically enhances their crystallinity, reduces their optical band gap, and improves electrical conductivity by shifting charge transport from two-dimensional to three-dimensional variable-range hopping, thereby establishing a clear structure-property relationship for applications in flexible electronics and sensing.
This study presents a low-cost, portable SERS platform utilizing gold nanoparticle-coated aluminum foil coupled with QuEChERS extraction to achieve sensitive and rapid detection of chlorpyrifos residues in honey by leveraging plasmonic enhancement and salt-induced nanoparticle aggregation to overcome matrix interference.
This study correlates the tensile and fatigue properties of three microalloyed high-strength structural steels with their microstructural characteristics, revealing that Steel 2 achieves superior fatigue strength through fine pearlite spacing enabling uniform cyclic deformation, while Steel 1 and Steel 3 exhibit distinct trade-offs between strength and ductility driven by grain size, carbon content, and dislocation behavior.
This study presents a noble-metal-free electrochemical sensor based on a SnS2/Co1Fe2@N-CNTs heterostructure that enables highly sensitive, cost-effective, and accurate detection of propyl gallate in packaged foods through synergistic interface engineering.
This paper introduces TASTET, a Python package that employs geometry-driven space-filling algorithms to efficiently select diverse, representative subsets of atomistic structures from large configurational ensembles, thereby maximizing the information gained from costly first-principles calculations without relying on prior energy estimates.
This study presents a rapid, ultra-sensitive, and reusable one-step semi-homogeneous fluorescent method for the multi-screening of 21 sulfonamides in milk, utilizing magnetic molecularly imprinted microspheres and aggregation-induced emission fluorophores to achieve detection limits in the pg/mL range with direct sample analysis after simple dilution.
This study reports the hydrothermal synthesis of mesoporous anatase TiO₂ nanoparticles using Pluronic F-127 and EDTA, which were characterized by various techniques and demonstrated a 76% efficiency in dye degradation for photocatalytic applications.
