Tertiary-Butyl Amine Functionalized Hierarchical Nano-Acrylic Copolymers for Energy- Efficient CO₂ Sequestration and Indoor Air Remediation

This study presents a novel tertiary-butyl amine functionalized hierarchical nano-acrylic copolymer synthesized via controlled emulsion polymerization that achieves highly efficient, energy-saving CO₂ capture (49.2% removal at 30°C) through chemical absorption, offering a sustainable solid-state alternative to traditional liquid amine scrubbing for indoor air remediation and direct air capture.

Iridium-Ruthenium Oxide for the Oxygen Evolution Reaction: Correlation between Calcination Temperature–Morphology–Activity Interplay

This study demonstrates that calcination temperature critically governs the morphology, crystallinity, and surface species of IrRuOx catalysts, revealing that while the amorphous phase synthesized at 350°C offers superior stability, the crystalline phase formed at 500°C exhibits the highest oxygen evolution reaction activity due to specific facet termination and optimal particle size.

L’Abbé Rearrangement Enables Access to N-Amino-1,2,3-Triazoles from Pyridotriazole Carbaldehydes with Hydrazine Derivatives

This paper presents a facile, efficient, and mild synthetic method for producing N-amino-1,2,3-triazoles from pyridotriazole carbaldehydes and hydrazine derivatives via an L'Abbé rearrangement and "snap-trapping" strategy, which offers high reactivity, broad functional group tolerance, and water as the sole byproduct.

Correlating Charge-Storage Kinetics, Quantum Capacitance, and Surface Charge Density in Bi2O2S: An Experimental-DFT Study

This study combines electrochemical experiments and density functional theory calculations to demonstrate that the rate-dependent charge storage in phase-pure Bi₂O₂S is dominated by diffusion-controlled processes, while surface modification significantly enhances its intrinsic quantum capacitance and electronic charge accumulation capabilities.

Technological affinities between qinghui and carbonaceous mortars from Baocheng and Yaotai walls at Xianling Mausoleum

This study identifies a technological affinity between the dark-grey mortars from the Xianling Mausoleum's Baocheng and Yaotai walls and traditional Chinese *qinghui* materials by demonstrating that their unique lime-carbonaceous composition, characterized by poorly ordered carbonaceous matter, was intentionally incorporated for specific pointing and finishing applications distinct from the bedding mortars.

The critical role of interface electrons in modulating the sensing behavior of Au/Pd and Pt/Pd resistive hydrogen sensors

This study employs density functional theory to demonstrate that engineering Au/Pd and Pt/Pd heterostructures modulates interface electron redistribution to significantly lower H₂ dissociation and desorption energy barriers, thereby enhancing the response speed, sensitivity, and reversibility of palladium-based hydrogen sensors.

Rheology of concentrated CNF suspensions following PEG and NaOH modification

This study establishes a quantitative rheological framework for concentrated cellulose nanofibril (CNF) suspensions, revealing that while polyethylene glycol (PEG) reduces viscosity through surface-site-limited interactions, sodium hydroxide (NaOH) induces stronger network disruption via hydroxide-driven swelling, with their combined use creating a highly deformable yet partially stabilized fibrillar network.
