In the present work, four polymeric nanocomposite PNC coatings were prepared with different concentrations of yttrium aluminum garnet nanoparticles YAG-NPs in polyvinyl butyral PVB matrix. The corrosion protection of the PNC coatings applied on the carbon steel surface was investigated in 1.0 M HCl solution by electrochemical impedance spectroscopy EIS. The YAG-NPs were synthesized by pulse ele...

In this study, Mg–2 wt% Zn scaffolds were fabricated by the powder metallurgy method, and effects of porosity content on microstructure, mechanical properties studied. Nanocomposite coatings deposited pulse electrodeposition (PED) method Mg–2Zn studied using a scanning electron microscope (SEM), X-ray diffraction (XRD), energy-dispersion spectrometer (EDS), Fourier transform infrared spectrosco...

In article number 2010638, Donald E. Ingber and co-workers report an anti-fouling porous conductive nanocomposite coating for electrochemical biosensors made of albumin intercalated with reduced graphene oxide, which enables sensitive selective multiplexed detection biomarkers in complex biological samples such as whole human blood ultra-low electrochemic al background.

A d.c. reactive magnetron sputtering technique was used to deposit (Ti, Si, Al)N films. The ion current density in the substrate was varied by the superimposition of an axially symmetric external magnetic field between the substrate and target. It was found that the variation of the magnetic field strength induced changes in the ion current density in the substrate with a consequent change in f...

Metal-ferroelectric-insulator-semiconductor (MFIS) devices were successfully fabricated using poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) and poly (methyl methacrylate): titanium dioxide (PMMA:TiO2) nanocomposite as ferroelectric and insulator films, respectively on n-type silicon (n-Si) substrate. Both ferroelectric and insulator films were prepared by sol-gel spin coating method. ...

This paper describes the development of an innovative carbon nanotube-based non-woven composite sensor that can be tailored for strain sensing properties and potentially offers a reliable and cost-effective sensing option for structural health monitoring (SHM). This novel strain sensor is fabricated using a readily scalable process of coating Carbon nanotubes (CNT) onto a nonwoven carrier fabri...

Platinum electrodes are commonly used electrocatalysts for oxygen reduction reactions (ORR) in fuel cells. However, this material is not economical due to its high cost and scarcity. We prepared an Mn(III) catalyst supported on graphene and further coated with polydopamine, resulting in superior ORR activity compared to the uncoated PDA structures. During ORR, a peak potential at 0.433 V was re...

Interfacial interactions play a crucial role in many complex materials systems, determining many of their properties. However, characterization of these interactions, especially at the microto nanometer length scales is experimentally challenging. Consequently, insufficient knowledge of these systems limits technological advances in important applications. In this work, custom functionalized at...

Nowadays due to water shortage, the use of air humidity as the sustainable solution has been considered by cities located in coastal zones; especially in warm and humid climate. However, the use of air humidity also has its own problems such as corrosion of metal parts in photovoltaic cells that used for energy supplying and they are often made of Aluminum alloy. Therefore different methods suc...
