Potato Peel Extract as an ecologically conscious Inhibitor for corrosion of A283 Carbon Steel in Hydrochloric Acid: Experimental and Theoretical Perspectives

This study demonstrates that potato peel extract acts as an effective, eco-friendly mixed-type corrosion inhibitor for A283 carbon steel in hydrochloric acid by forming a protective adsorbed film, with its performance validated through comprehensive experimental characterization and theoretical analysis identifying petunidin and chlorogenic acid as the primary active constituents.

Synthesis and properties of poly (propylene carbonate)-based waterborne polyurethane for hot melt adhesives

This study demonstrates the successful synthesis and optimization of poly(propylene carbonate)-based waterborne polyurethane (PPC-WPU) for high-performance hot melt adhesives by systematically investigating how the R value, DMPA content, and HDI/IPDI ratio influence the emulsion properties, thermal characteristics, and adhesion strength of the resulting films.

Single-atom orbital engineering of plasmonic hot-electron dynamics for ultrafast non-thermal water dissociation

This study utilizes real-time time-dependent density functional theory to demonstrate that substituting a single silver atom with gold in a plasmonic nanocluster fundamentally reconfigures excited-state dynamics, enabling ultrafast (40 fs) non-thermal water dissociation via resonant hot-electron injection into O-H antibonding orbitals.

Ligand exchange and stability of CdTe nanoplatelets under mild conditions

This study demonstrates that while CdTe nanoplatelets synthesized under specific precursor stoichiometries maintain their excitonic optical signatures under mild storage conditions, they exhibit limited tolerance to common CdSe-derived ligand-exchange protocols, often resulting in colloidal destabilization or surface-induced optical changes.

Improvement in the bandgap and photoluminescence behavior by Holmium (Ho) and Iron (Fe) co-doping in LaNiO 3, synthesized using sol-gel route for novel sustainable energy applications

This study demonstrates that co-doping LaNiO₃ perovskites with Holmium and Iron via a sol-gel route successfully tailors their structural, electronic, and optical properties—specifically reducing the bandgap and modifying photoluminescence behavior—to enhance their performance for novel sustainable energy applications.

Short-time solution heat treatment of recycled A383 HPDC alloy: microstructure–property relationships and ensemble machine learning analysis

This study demonstrates that a blister-free short-time solution heat treatment at 490°C for 90–120 minutes significantly enhances the ductility of recycled A383 HPDC alloy by promoting eutectic Si spheroidization and Cu homogenization, while ensemble machine learning models, particularly AdaBoost, effectively corroborate this optimal processing window that reduces conventional treatment duration by approximately 80%.

By-Layer Covalent Organic Structure as a Metal-Free PCET Catalyst for Efficient Oxygen Evolution in Alkaline and Neutral Media

This study reports a metal-free, bilayer covalent organic structure (COS) catalyst that enhances oxygen evolution in neutral and alkaline media by actively reorganizing interfacial water networks to facilitate proton-coupled electron transfer, where O–H bond cleavage is not the rate-determining step.

Effect of TEMPO oxidation and Homogenization Passes on the Properties of Nanocellulose and its Composites

This study demonstrates that bamboo nanofibrillated cellulose (NFC) produced via TEMPO oxidation and high-pressure homogenization can serve as a sustainable, bio-based binder for wood composites, where increasing homogenization passes enhances fibrillation and hot-pressed composite performance despite limitations in moisture resistance and ultimate mechanical strength compared to synthetic resins.
