Phytochemical-Assisted Low-Temperature Hydrothermal Crystallization of Defect-Engineered ZnO Nanoparticles Using Madhuca longifolia Flower Extract: Structural Evolution and Tunable Optical Properties

This study demonstrates a sustainable, calcination-free hydrothermal method using Madhuca longifolia flower extract to synthesize defect-engineered, phase-pure ZnO nanoparticles at 80–100 °C, where increasing temperature enhances crystallinity and reduces oxygen vacancies to yield tunable optical properties suitable for advanced optoelectronic and sensing applications.

Effect of Surface-Modified Silica Nanoparticles on Cellular Structure and Sound Absorption Behavior of Polyurethane Foams

This study demonstrates that surface-modifying silica nanoparticles with silane coupling agents, particularly APTES, enhances their dispersion and interaction within polyurethane foams, leading to more uniform cellular structures and significantly improved sound absorption performance at mid-to-high frequencies.

A Facile Green Synthesis of Polyethyleneimine-Functionalized Graphene Oxide Frameworks with Enhanced CO₂ Capture and Selectivity

This study demonstrates that solvent-controlled synthesis strategies critically influence the conformation and loading of polyethyleneimine on graphene oxide frameworks, with aqueous-based processing yielding the highest CO₂ uptake (35 cc g⁻¹) and selectivity by promoting an extended polymer structure and maximizing accessible amine sites compared to ethanol-mediated or covalent grafting methods.

A modular active learning framework for autonomous atomic layer deposition

This paper presents a closed-loop autonomous platform integrating an automated PE-ALD tool, in situ characterization, and a Gaussian process-based active learning framework that efficiently maps high-dimensional synthesis-property relationships for TiO2 deposition, significantly outperforming random sampling in predictive accuracy and enabling targeted process optimization with far fewer experiments.

Computational discovery and proof-of-concept synthesis of super-ordered quinary MAB phases (s-MAB) with combined in-plane and out-of-plane chemical ordering

This study combines computational screening and proof-of-concept synthesis to discover and validate a new family of thermodynamically stable, super-ordered quinary MAB phases (s-MAB) that uniquely feature simultaneous in-plane and out-of-plane chemical ordering, thereby expanding the structural diversity and mechanical properties of layered borides.

Is the pyrimidine the proton-handling element of the genetic alphabet? A quantum-chemical test of a proton-centred account of infectious disease

This study employs quantum-chemical calculations to test a proton-centred theory of infectious disease, finding that while the proposed hypothesis regarding pyrimidine basicity requires reformulation, the framework's predictions concerning tautomeric shifts in base analogues and resonance stabilization energies are validated.
