“…[9] The polyacrylamide grafted guar gum is reflected as a good corrosion inhibitor for mild steel in 1 M hydrochloric acid with 90% inhibition efficiency. [12] However, in sulfuric acid, the results obtained show different behavior. Carboxymethyl cellulose (CMC) acts as inhibitor for mild steel in sulfuric acid and the inhibition efficiency was found to increase with increase in CMC concentration (the maximum value is 64% at 0.5 g L −1 CMC) but decreased with rise in temperature.…”

This paper aims to increase the inhibition efficiency of gum arabic (GA) for the corrosion of API5L X70 pipeline steel in sulfuric acid through the addition of halide ions (potassium iodide [KI], potassium chloride [KCl], and potassium bromide [KBr]). The synergistic effect of GA and halide ions has been studied using potentiodynamic polarization curves, electrochemical impedance spectroscopy, and surface analysis by scanning electron microscope (SEM). The results show that substantial corrosion inhibition (99%) using 2 g L−1 GA and 0.5 mM KI can be obtained in synergistic manner. The adsorption of GA in combination with iodide ions follows Langmuir adsorption isotherm. GA combined with KI acts as a mixed‐type inhibitor in sulfuric acid.

“…Technological advancements in ceramic powder synthesis, forming, sintering, and HIPing, have made possible a wide range of compositions, e.g. Y 2 O 3 [24], Y 2 O 3 -La 2 O 3 [25], MgAl 2 O 4 (magnesium aluminate spinel) [26], YAG (yttrium aluminate garnet) Y 3 Al 5 O 12 [27], and AlON: Al 23 O 27 N 5 [28], and shapes (cylindrical, bulgy, spherical, and elliptical), presenting significant flexibility to the design of lamps. Ceramics of cubic symmetry are transparent in the polished state; the cubic symmetry limits birefringent light scattering at grain boundaries.…”

Ceramics contributes to progression of civilization. Yet advancement of ceramic science and technology benefits from the improved infrastructure and productivity. This paper assesses the development of structural and optical ceramics in the last quarter century. For example, structural ceramics such as silicon carbide whisker reinforced alumina matrix and titanium carbide dispersed silicon carbide matrix composites have made possible high-speed, wear-resistant, specialty tools. Designing of the structural materials involved consideration of thermodynamic compatibility of phases during fabrication, and consideration of the initiation and propagation of fracture. Mechanisms of the observed toughening have been proposed on a scale ranging from continuum to microstructure to atomistics. Optical ceramics including translucent polycrystalline alumina have facilitated the construction of high-pressure sodium and ceramic metal halide lamps. The microstructure and properties such as transmittance and sodium resistance of polycrystalline alumina have improved. The starting powders improved in purity, particle size, and de-agglomeration. Sintering of alumina advanced through optimization of dopants and sintering atmosphere. Densification involves grain-boundary diffusion; retardation of grain growth is due to solute drag. The solid solubility of magnesia sintering aid in alumina is a function of grain size. During grain growth and sintering of magnesia-doped alumina, both the enriched dopant level at grain boundaries and the equilibrium dopant content in the lattice alter, resulting in boundary pinning and pore annihilation. Oxygen vacancies when in motion significantly influence the boundary transport, and when stationary are important to optical properties of the sintered alumina. Further development of improved and new functional ceramics involves consideration of energy and environmental renewability. Prior achievements and outstanding challenges will be discussed.

“…Similar with imidazole derivatives, another type of efficient corrosion inhibitors, amide compounds, adsorb on metal surface through the coordination bond between amide groups and iron (Fe). [18][19][20][21][22][23] However, both the imidazole derivatives and amide compounds cover the metal surface with the mono-layer and self-assembly films. Hence, combining the strong adsorption properties of imidazoles and the self-assembled characteristics of HBAs amides, the architectures of nano-scaled and multi-layer aggregation films are meaningful and practical.…”

An efficient corrosion inhibitor named BTA‐IM is reported in this contribution. The inhibition performance of BTA‐IM for carbon steel in 1 M HCl is investigated and the possible inhibition mechanism is proposed. According to weight‐loss experiments, the inhibition efficiency of BTA‐IM can reach to 98%. Secondly, the morphology investigation illustrates that the nano‐scaled, dendrimer‐like, and multi‐layer films cover the metal surface regularly and compactly through self‐assembly. Thirdly, the thickness of the films on surface of metal is gradually increased with the increasing dosage of inhibitor, and the aggregated films are obtained. Possibly, the aggregated films are born of absorption films and the increased concentration of BTA‐IM, giving rise to the regular and compact films.
