    Enhanced Corrosion-Inhibition performance of amino Gossypol: A comprehensive theoretical study
    (Elsevier, 2024) Berdimuradov, Khasan; Berdimurodov, Elyor; El Ibrahimi, Brahim; Demir, Muslum; Colak, Suleyman Gokhan; Tuezuen, Burak; Rakhmatullaeva, Mavjuda
    This study highlights the potential of amino gossypol as a green corrosion inhibitor. Comprehensive DFT calculations reveal that the electronic properties of amino gossypol, including HOMO and LUMO values, which indicate its strong electron transfer capacity and effective adsorption on steel surfaces. DFT research demonstrates a good electron transfer capacity with HOMO and LUMO values of -5.1103 eV and -0.947 eV, respectively. The study employs (molecular dynamics (MD) and Monte Carlo (MC)) simulations to investigate the interaction dynamics of amino gossypol with steel, demonstrating robust adsorption energy and the formation of a stable protective layer. The inhibitor's adsorption energy of -65.108 Kcal/mol shows robust and spontaneous adhesion to steel, increased by its optimized molecular structure and physisorption and chemisorption methods. The substantial polarizability (gamma DFTInh = 452.31) and specific charge distribution, with significant negative charges on oxygen atoms, facilitate efficient corrosion inhibition. Theoretical results, including reactivity indices such as chemical softness (0.4804) and electrophilicity index (2.2031), establish a strong platform for future practical investigation and possible commercial use of amino gossypol. MD simulations confirm the formation of a stable and persistent protective layer on Fe(110) surfaces. Amino gossypol is presented as an environmentally friendly and sustainable corrosion inhibitor, aligning with the growing demand for green industrial solutions. The theoretical and computational analyses predict significant corrosion inhibition performance of amino gossypol, supported by its optimized molecular structure and strong binding affinity to steel.

    Phytochemicals/Plant Extracts as Corrosion Inhibitors for Magnesium in H2SO4Solutions
    (CRC Press, 2024) Berdimuradov, Khasan; Kholikov, Abduvali; Akbarov, Khamdam; Berdimurodov, Elyor; Ibrahimi, Brahim El; Tuzun, Burak; Es-Soufi, Hicham
    This chapter provides a comprehensive overview of utilizing phytochemicals and plant extracts as green, sustainable corrosion inhibitors for magnesium metal in contact with sulfuric acid (H2SO4) solutions. It begins by highlighting the importance of effective corrosion inhibition for magnesium alloys across industrial applications. The role of phytochemicals as corrosion inhibitors is then discussed, including their extraction from plant sources, adsorption mechanisms, structural effects, and comparative advantages over traditional inhibitors. Key topics covered include phytochemical characterization techniques, quantitative structure–activity relationship modeling, optimization strategies, case studies demonstrating their inhibition efficacy, and challenges associated with their large-scale production and application. The environmental and economic benefits of phytochemicals over conventional inhibitors are emphasized. This chapter concludes by underscoring the promise of phytochemicals as an emerging alternative for efficient and eco-friendly corrosion protection of magnesium alloys in acidic conditions across industries. © 2024 selection and editorial matter, Chandrabhan Verma, Ashish Kumar, and Abhinay Thakur; individual chapters, the contributors.

    Synthesis methods and description for new derivatives associated with 8-hydroxyquinoline and their use as acidic corrosion inhibitors for steel and other alloys: a review
    (Walter De Gruyter Gmbh, 2024) Rbaa, Mohamed; Berdimurodov, Elyor; Tuzun, Burak; Berdimuradov, Khasan; Zarrouk, Abdelkader
    The field of corrosion has recently been considered a productive field for scientific research. With the increasing use of metals in several industrial fields, such as metal construction, the construction of arches and the automobile industry, the problem of corrosion is an important issue. To solve the corrosion problem of metal materials, several methods have been discovered to combat this phenomenon, such as process control, cathodic protection, organic and inorganic coatings. Nonetheless, the presentation of corrosion inhibitors, particularly organic inhibitors, stays the least expensive and simplest technique for the insurance of metals against consumption in acidic media. In this work, it was summed up the strategies for amalgamation and portrayal of newly innovative heterocyclic complexes from 8-hydroxyquinoline, their inhibition performances for M-steel, C40E steel and C35E steel in acidic conditions, for example, hydrochloric acid, sulfuric acid, etc.

    Utilization of Encapsulated Corrosion Inhibitors in the Biomedical Industry
    (CRC Press, 2024) Berdimuradov, Khasan; Berdimurodov, Elyor; Brahim, El Ibrahimi; Tuzun, Burak; Es-Soufi, Hicham; Mallick, Sadhucharan; Borikhonov, Bakhtiyor
    Encapsulated corrosion inhibitors have garnered significant interest as a means to improve the corrosion protection of biomedical devices and materials. These systems encapsulate corrosion inhibitors within protective matrices, providing enhanced corrosion protection, controlled release and targeted delivery, and improved biocompatibility. This chapter discusses the release mechanisms of encapsulated corrosion inhibitors, including passive and stimuli-responsive mechanisms, and factors affecting their release from encapsulation systems. The advantages and challenges of encapsulated corrosion inhibitors in biomedical applications are also explored, along with emerging trends, technologies, and potential research directions. Encapsulated corrosion inhibitors hold great promise for enhancing the performance, longevity, and biocompatibility of biomedical devices and materials, but further research and development are required to fully exploit their potential in practical applications. © 2025 selection and editorial matter, Ashish Kumar and Abhinay Thakur.
