“…These graphs demonstrate that charge transfer mostly regulated the corrosion process [50]. The departure from a perfect semicircle can be attributed to frequency dispersion and surface heterogeneities [51]. To upgrade the exactness of the fitting handle, we have introduced into the circuit is a constant phase element (CPE) as a replacement for the conventional double‐layer capacitor [30].…”

Different electrochemical techniques, such as electrochemical “impedance spectroscopy (EIS), electrochemical frequency modulation (EFM), and potentiodynamic polarization (PDP), and mass reduction at various temeratures were used to evaluate the inhibitory potential of Terfeziaceae extract as a corrosion inhibitor for Cu in HNO3 corrosive arrangements. The adsorption was analyzed utilizing Temkin adsorption isotherm, and the adsorption factors were considered. The detections illustrated that the Terfeziaceae extract shown maximum inhibition capacity (% IE) reached to 98.1% at concentration of 300 ppm, 25°C. “x‐ray electron spectroscopy (XPS), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) surface study techniques have all supported the existence of a protective layer on the Cu surface. This extract operates as a mixed‐type inhibitor, according to PDP data.” The current research presents highly significant findings in the preparation and design of original, environmentally friendly, sustainable inhibitors with high inhibitory power.

Recent trends in thermo‐responsive elastomeric shape memory polymer nanocomposites

Shape memory polymers (SMPs) are polymeric smart materials, a class of stimuli‐responsive polymers that can return to their initial shape from a programmed temporary shape under the application of external stimuli, such as light, heat, magnetism, and electricity. Because of these unique features, SMPs can find applications in many fields, like aerospace, biomedical devices, flexible electronics, soft robotics, shape memory arrays, and 4D printing. The comparatively low density, low cost, easy biodegradability, and biocompatibility make SMPs a better candidate for shape memory applications. Among them, thermo‐responsive SMPs can revert to their permanent shape depending on a temperature greater than their polymer transition temperature. Thermo‐responsive SMPs combine semi‐crystalline or elastomeric polymers with improved mechanical and electrical properties. Integrating nanofillers into the polymer elastomer matrices can further enhance these properties, forming shape‐memory polymer nanocomposites (SMPNCs). This review focuses on the basics, design, and classifications of thermo‐responsive SMPs and the characteristics of elastomers and blends of polymers used. Incorporating various nanofillers to get SMPNCs to have improved properties over SMPs is also presented. The importance of Tg (glass transition temperature) and Tm (melting temperature) based SMPs and SMPNCs, various elastomers used, and the methods for preparation like solution casting, melt compounding, in situ polymerization, and their possible future applications are also discussed.

“…A layer of nickel alloy coating on the surface of steel may improve the corrosion resistance and reduce the cost of using Ni-based alloys. Although nickel-based alloys have high corrosion resistance, as a medical material implanted into the human body for a long time [17,18], it is low-toxic and may lead to biological fouling. Many metals, such as silver [19], copper, and zinc have antibacterial functions.…”

To reduce the destruction of organic biological fouling in marine steel, nickel-based (NiCrAlY) transition coatings with and without silver (Ag) doping were prepared on AH32 marine steel by plasma spraying. The coatings exhibited a layered structure, and AlNi 3 ( 111), ( 200), and (220) diffraction peaks were detected. The Ag (111) peaks were also observed for the Ag-doped coatings. The number of sulphate-reducing bacteria (SRB) adsorbed on the coating surfaces reduced after immersion in the bacterial solution, and their shells were disintegrated because of the presence of Ag. The corrosion potentials of AH32, NiCrAlY, and NiCrAlY(Ag) coated AH32 plates were nearly identical at approximately −720 mV. After being covered with organic paint, the corrosion potential and current density of the NiCrAlY(Ag) coating increased to −624 mV and decreased by one order of 2.75 × 10 −6 A cm −2 , respectively. The NiCrAlY(Ag) coating effectively inhibited biological fouling.
