Sol–gel processing and characterization of (RE-Y)-zirconia powders for thermal barrier coatings [PDF]

open access: yes, 2011
The effect of doping on the structural, morphological and thermal properties of ZrO2–XO1.5 (X=Y, La, Sm, Er) solid solutions for thermal barrier (TBC) applications was investigated. Oxide powders of various compositions from 9.7 to 40 mol% XO1.5 (X=Y, La,

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

open access: yesAdvanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

open access: yesAdvanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Nanostructured Coatings Approach for Corrosion Protection of Building Steels [PDF]

open access: yesE3S Web of Conferences
Corrosion of steel reinforcement is a persistent durability concern for concrete structures, since conventional coatings often fail to provide lasting protection due to poor adhesion and insufficient barriers in harsh environments.

Water‐resistant latex coatings: Tuning of properties by polymerizable surfactant, covalent crosslinking and nanostructured ZnO additive [PDF]

open access: yes, 2021
This paper deals with the development of acrylic latexes providing high‐performance wa-ter‐resistant coatings. For this purpose, mutual effects of anionic surfactant type (ordinary and polymerizable), covalent intra‐ and/or interparticle crosslinking ...

Nanostructured diamond coatings for orthopaedic applications [PDF]

open access: yes, 2013
With increasing numbers of orthopaedic devices being implanted, greater emphasis is being placed on ceramic coating technology to reduce friction and wear in mating total joint replacement components, in order to improve implant function and increase device lifespan.

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

open access: yesAdvanced Functional Materials, EarlyView.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Self-lubrication and enhanced wear and corrosion resistance of calcium silicate hydrate nanostructures on Ti-based micro-arc oxidized coatings

open access: yesSmart Materials in Manufacturing
Nanostructured coatings for titanium (Ti)-based implants are well-known for their biological properties; however, they are highly fragile in service. The debris generated by wear and coating destruction can lead to chronic inflammatory response, bone ...
