Summary: The study confirmed that nutmeg oil is an effective inhibitor for the corrosion of CSL-52 in hydrochloric acid solution, with increasing inhibition efficacy observed with higher nutmeg oil concentration and lower temperature. Electrochemical and computational studies showed that nutmeg oil acted as a mixed inhibitor and played a significant role in the corrosion inhibition process. This research also aimed to predict the inhibitory potency of the four molecular constituents of nutmeg oil through computational work.

Summary: The application of green and sustainable anticorrosive coatings for metallic materials is of growing interest. In this study, a stable crystalline chitosan/gum Arabic composite (CGAC) nanopowder was successfully synthesized and tested for its anticorrosion ability on mild steel. The results showed that the nanocomposite coating provided good corrosion resistance, with higher doses of CGAC resulting in increased protection efficiency. Additionally, the coating was found to block corrosive sites on the steel surface and protect against aggressive chloride ions.

Summary: In this study, Oregano (Origanum vulgare) leaf essential oil was investigated as an environmentally friendly corrosion inhibitor for carbon steel in hydrochloric acid. The corrosion inhibition mechanism was studied through surface morphology analysis, electrochemical tests, weight loss measurements, theoretical calculations, and computational methods. The results showed that O. vulgare had the highest inhibition performance of 85.64% at a concentration of 2 g/l in 1 M HCl. The adsorption of the O. vulgare inhibitor on the metal surface was attributed to the formation of rigid covalent bonds, and the hydroxyl functional groups and benzoyl rings were found to be the main contributors to the high inhibition efficiency.

Summary: The synergistic inhibition effect of Eupatorium adenophora Spreng leaves extract (EASLE) and potassium iodide (KI) on the corrosion of cold rolled steel (CRS) in 5.0 M H3PO4 solution was investigated. The results showed that EASLE and KI exhibited a synergistic effect, with a maximum inhibition efficiency of 97.9%. The presence of KI facilitated the adsorption of EASLE, and the synergistic mixture acted as a mixed inhibitor, retarding the cathodic reaction. The surface of CRS treated with EASLE/KI appeared non-corroded and more hydrophobic.

Summary: A new staged acid corrosion inhibition (ACI) concept using polymerisable ACIs has been developed to minimize the corrosion of coiled tubing and wellbore casing materials during matrix acidizing operations. This approach, with a high ACI concentration in the initial stage and a reduced concentration in the later stage, can maintain good film persistency and low corrosion rates.

Summary: The study demonstrated the effectiveness of Inula viscosa leaf extract as a corrosion inhibitor for X70 carbon steel in 1 M HCl, with inhibition efficiency exceeding 92% at a concentration of 600 mg L-1. The adsorption of the green inhibitor onto the steel surface, mixed-type behavior, and stability of the inhibitor layer were key factors contributing to its excellent performance. Analysis of the protective film formed by the inhibitor, reduction of surface roughness, and quantum chemical parameters calculated for the plant extract components using DFT further supported the findings.

Summary: The objective of this study was to evaluate the effects of starch, lipid, and protein components in flour on the mechanical properties of Indonesian Biji Ketapang (BK) cookies. The results showed that the rheological properties of flour, influenced by starch, lipid, and protein, affected the spread ratio and the internal pores of the cookies. Different types of flours resulted in cookies with different pore sizes. Low-protein content in flour contributed to cookies with better crispness and hardness. These findings are important for the production of gluten-free foods.

Summary: In this study, new substituted ligands based on pyrazole (L-1-L-4) were synthesized via a one-step condensation reaction. These ligands formed in situ complexes with various copper (II) salts, and catalyzed the oxidation of catechol to o-quinone. The catalytic activity depended on the ligand, counterion, and solvent. The complex formed by L-2 and Cu(CH3COO)(2) exhibited the highest catalytic activity in methanol.

Summary: This study evaluated the corrosion inhibition potential of acetylsalicylic acid (ASA) on carbon steel in an acidic environment. Both electrochemical and gravimetric measurements were used to assess the corrosion performance of ASA on carbon steel in a 1M hydrochloric acid solution. The results revealed that ASA effectively inhibited the corrosion of carbon steel in an acidic environment. The inhibition efficiency increased with increasing ASA concentration and decreased with increasing temperature. The maximum inhibition efficiency of 96% was achieved with a concentration of 5 x 10-3 M ASA at 308 K. The adsorption of ASA on the carbon steel surface followed the Langmuir model, and a physical adsorption mechanism was proposed based on the experimental results.

Summary: Canola is a major oilseed crop with various uses in food, feed, and industrial sectors due to its high oil content and favorable fatty acid composition. However, factors throughout the production and processing cycle can affect the quality of canola grains and their derived products, compromising their chemical composition, physical properties, functional characteristics, and sensory attributes. Therefore, it is important to optimize production and processing methods to ensure the safety, stability, and suitability of canola for different food applications. This literature review provides a comprehensive overview of how these factors affect canola quality and suggests future research needs and challenges for enhancing its utilization in food.

Summary: This study compared the chemical composition and investigated the anti-diabetic and antioxidant properties of different extracts obtained from Gracilaria bursa-pastoris collected from the Nador lagoon in Morocco. The fatty acid analysis revealed high levels of unsaturated fatty acids, and the HPLC analysis identified ascorbic and kojic acids as the prevalent phenolic compounds. The aqueous extract exhibited significant levels of polyphenols and flavonoids, with strong scavenging ability against DPPH radicals, and all extracts showed inhibitory effects on α-amylase and α-glucosidase activity. Molecular docking models demonstrated that the identified phytochemicals in G. bursa-pastoris extracts have better enzyme activity reduction ability than the commercially available drug acarbose.
