This study demonstrates that a thermochemically modified oyster shell biosorbent (CMOS) is an effective, sustainable, and reusable material for the simultaneous removal of Pb²⁺ and Hg²⁺ from aqueous solutions, achieving high adsorption capacities and selectivity through chemisorption mechanisms.
This study demonstrates a synergistic sequential pretreatment using dilute phosphoric acid followed by a choline chloride-lactic acid deep eutectic solvent to efficiently fractionate sugarcane bagasse into high-purity cellulose pulp and structurally preserved lignin with minimal degradation, offering a sustainable pathway for integrated biorefinery applications.
This study demonstrates that KOH-activated biochar derived from waste cigarette filters serves as an effective, low-cost adsorbent for removing Cu(II) from aqueous solutions by significantly enhancing surface area and oxygen-containing functional groups through pyrolysis and chemical activation.
Mechanical milling of the 0.39BaTiO₃–0.31SrTiO₃–0.30KNbO₃ ternary system for 20 hours yields a nanocrystalline perovskite exhibiting relaxor ferroelectric behavior, n-type semiconductivity, and exceptional electrochemical performance, making it a promising candidate for next-generation energy storage and optoelectronic applications.
This study demonstrates that synergistically combining low-consistency refining with unrestrained drying significantly enhances paper extensibility to 21.1% without compromising tensile strength by inducing fiber fibrillation and modifying cellulose supramolecular organization, thereby offering a promising solution for sustainable packaging.
This study reports the first crystallographic characterization of a stable, planarized C18²⁻ macrocycle that adopts a triplet ground state with Baird aromaticity, thereby avoiding the typical loss of aromatic stabilization upon reduction to a 4n π-electron system.
This study demonstrates that incorporating 2D Zn–HHTP metal–organic frameworks into PVDF creates a tunable platform where piezoelectric and triboelectric nanogenerator performances are optimized at different filler concentrations (1 wt% and 3 wt%, respectively) because piezoelectric output relies on bulk polarization while triboelectric output depends on interfacial charge processes and surface properties.
This study investigates the green aqueous-phase free radical synthesis of polycarboxylate superplasticizers (PCEs) to determine their reaction kinetics and optimization parameters, revealing that the process follows a pseudo-second-order mechanism with acrylic acid concentration being the most significant factor influencing the polymerization rate.
This study demonstrates that synthesizing chitosan-loaded Ce–Fe oxide magnetic biochar (CCFBC) significantly enhances methylene blue adsorption through a synergistic mechanism involving amino and metal-oxide functional groups, achieving a maximum capacity of 142.8 mg·g⁻¹.
This paper reports the rapid, wet-chemical synthesis of stable, self-assembled Rhodium-CTAB organosols with nanochain morphology that demonstrate superior catalytic activity in nitroarene reduction and high surface-enhanced Raman scattering performance compared to existing methods.
