Article Abstract
A study has been presented on the effects of intrinsic mechanical parameters, such as surface stress, surface elastic modulus, surface porosity, permeability and grain size on the corrosion failure of nanocomposite coatings. A set of mechano-electrochemical equations was developed by combining the popular Butler-Volmer and Duhem expressions to analyze the direct influence of mechanical parameters on the electrochemical reactions in nanocomposite coatings. Nanocomposite coatings of Ni with Al₂O₃, SiC, ZrO₂ and Graphene nanoparticles were studied as examples. The predictions showed that the corrosion rate of the nanocoatings increased with increasing grain size due to increase in surface stress, surface porosity and permeability of nanocoatings. A detailed experimental study was performed in which the nanocomposite coatings were subjected to an accelerated corrosion testing. The experimental results helped to develop and validate the equations by qualitative comparison between the experimental and predicted results showing good agreement between the two.

This study demonstrates the successful fabrication of nanostructured Langmuir-Blodgett (LB) films combining the conjugated copolymer poly(9,9-dioctylfluorene--3,4-ethylenedioxythiophene) (PDOF--PEDOT) with spherical and triangular silver nanoparticles (AgNP). The LB technique allowed precise control over the molecular arrangement and distribution of the nanoparticles at the air-water interface, resulting in compact, reproducible and structurally ordered nanocomposite films. The structural and morphological properties of the interfacial monolayers and LB films were investigated using surface pressure-area isotherms, Brewster angle microscopy, polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS) and quartz crystal microbalance.

Purpose: This study aimed to develop a composite nanozyme system (Au/PB-Ce6-HA) based on gold nanoparticles (AuNPs) and Prussian blue nanoparticles (PBNPs) to combat tumor hypoxia and insufficient endogenous hydrogen peroxide (HO) deficiency, thus enhancing the efficacy of sonodynamic therapy (SDT) and starvation therapy for liver cancer.
Methods: The Au/PB-Ce6-HA system was constructed by in situ embedding AuNPs on PBNPs, loading the sonosensitizer Chlorin e6 (Ce6), and surface-coating with thiolated hyaluronic acid (HA-SH). The system was evaluated both in vitro and in vivo to assess its ability to catalyze glucose to generate HO, decompose HO to produce oxygen, and generate highly toxic reactive oxygen species (ROS) under ultrasound irradiation.

In this work, cerium oxide nanoparticles prepared through the solvothermal route (sCeO NPs) are integrated into chitosan (CH) matrices to serve as an efficient coating for banana preservation. The morphological, structural, mechanical, and water-barrier properties of nanocomposite films integrated with various sCeO concentrations were investigated to determine the optimal sCeO NPs concentration within the film matrix. Furthermore, the sensory evaluation and physicochemical properties of the coated and uncoated bananas, including visual attributes, peel browning, CO production, firmness, weight loss, ripening rate (based on total soluble solids and titratable acidity), and pH, are considered during storage.

Rapid and precise detection of () is crucial for early diagnosis, treatment of infectious ailments, and controlling outbreaks. Herein, we present a rapid, streamlined, and sensitive method for screening based on a hollow copper/platinum interspersed graphene oxide nanosheets (Cu/Pt-GO)-mediated cascade responsiveness strategy. The Cu/Pt-GO nanozymes were proposed to catalyze the colorless 3,3',5,5'-tetramethylbenzidine (TMB) to colored oxidized TMB (oxTMB) with enhanced SERS signals, achieving colorimetric/SERS dual-model detection.
