Hierarchical polymer architectures governed by diffusion–reaction competition Decoupling morphology, packing and density in covalent systems

This study establishes that hierarchical polymer architectures are governed by the competition between reaction kinetics and mass transport, quantified by an effective Damköhler number, which enables the decoupling of macroscopic morphology from invariant molecular packing and density across diverse chemical systems.

Investigation of the microstructure and mechanical properties of the Al-13.8 wt. % Mg 2 Si- Zr cylinder fabricated by the centrifugal casting

This study demonstrates that adding Al-5Zr to an Al-13.8 wt.% Mg2Si alloy during centrifugal casting refines the Mg2Si particle morphology, alters the fracture mode from cleavage to ductile dimples, and significantly enhances the hardness and tensile strength across all radial layers of the resulting functionally graded cylinder.

The Influence of the Bleaching Process on the Production of Nanocellulose From Eucalyptus

This study demonstrates that varying bleaching sequences have no statistically significant impact on the yield or dimensions of nanocellulose produced from *Eucalyptus urograndis* pulp, indicating that acid hydrolysis is the primary governing factor and allowing for greater flexibility in selecting industrial pulp qualities.

Valorization of Petroleum coke into High-Quality Few-Layer Graphene through Liquid-Phase Exfoliation

This paper presents a scalable, non-oxidative method that converts low-value petroleum coke into high-quality, few-layer graphene nanosheets with high conductivity and stability through sequential isopropanol pre-treatment, thermal desulfurization, and CO₂-assisted liquid-phase exfoliation.

Valorization of local Indonesian sago starch into hard carbon as anode materials for sodium-ion batteries

This study demonstrates that hard carbon anodes derived from local Indonesian sago starch via a urea-assisted hydrothermal route exhibit superior electrochemical performance for sodium-ion batteries, achieving a high reversible capacity of 265 mAh g⁻¹ after 100 cycles due to beneficial nitrogen doping, large interlayer spacing, and a sphere-like morphology.

Heavy Metal Removal from Electroplating Wastewater Using Polymer Ligand Composed of Bamboo Cellulose

This study demonstrates that a bamboo cellulose-based poly(amidoxime) ligand, synthesized via grafting and amidoximation, effectively removes heavy metals from electroplating wastewater with high adsorption capacities and up to 99% recovery efficiency under pH-dependent monolayer adsorption conditions.
