The journal aims to provide a forum for the disseminations and exchanges of scientific and technological knowledge based on original research works among those linked to advanced coatings study, development and/or production, focusing in different areas such as wear-resistant coatings, corrosion protective coatings, optical protective coatings, films for biomedical and energy purposes, decorative coatings, and others, produced by advanced techniques such as PVD, CVD, thermal projection, etc.</span></span></span></p> https://mail.lifescienceglobal.com/pms/index.php/jcst/article/view/9760 Conditions of Formation of α- and β-Modifications of Ge3N4 and Preparation of Germanium Oxynitride Dielectric Films 2024-09-04T09:59:43+00:00 Zurab V. Wardosanidze zvward@yahoo.com Irakli Nakhutsrishvili iraklinakhutsrishvili52@gmail.com Revaz Kokhreidze info@lifescienceglobal.com <p>The binary compound of germanium with nitrogen (Ge<sub>3</sub>N<sub>4</sub>) is used in various fields of science and technology. Among the experimentally discovered and theoretically predicted crystal modifications of Ge<sub>3</sub>N<sub>4</sub> at ordinary pressures and temperatures, only the α- and β-phases of the nitride are stable. There are conflicting data in the literature on the conditions for the formation of these phases. The main methods for obtaining Ge<sub>3</sub>N<sub>4</sub> are the nitridation of elemental germanium and its dioxide with ammonia. The present work studied the influence of the degree of humidity of ammonia on the possibility of the formation of pure α- and β-phases and their mixtures. It is shown that it is possible to obtain nitride with practically any ratio of these phases by varying degrees of humidity and the temperature of the process. During the process, the formation of germanium nitride is accompanied by its simultaneous evaporation. Oxidation with water vapors also produces volatile monoxide. Simultaneous evaporation of germanium nitride and oxide results in the deposition of a film of germanium oxynitride in the cold zone of the reactor. This film is a germanium oxynitride used in microelectronics as a dielectric layer in Metal-Insulator-Semiconductor systems.</p> 2024-09-04T00:00:00+00:00 Copyright (c) 2024 https://mail.lifescienceglobal.com/pms/index.php/jcst/article/view/9945 Recent Advancements in Graphene Derivative-Based Nanocomposites: Innovations in Coating and Sensing Technologies 2024-12-11T08:15:31+00:00 Nadia Khan info@lifescienceglobal.com Zahra A. Tabsi info@lifescienceglobal.com Baiyu Zhang info@lifescienceglobal.com Yuming Zhao yuming@mun.ca <p class="04-abstract">Graphene derivative-based nanocomposites have emerged as innovative solutions to address challenges in corrosion, marine biofouling, and environmental contamination. This review highlights recent advancements in three key areas: (1) dual-barrier and self-healing anti-corrosion materials, (2) eco-friendly anti-biofouling coatings, and (3) high-efficiency electrocatalytic films for electrochemical sensing. We emphasize the critical roles of graphene (Gr) sheets, graphene oxide (GO), and reduced graphene oxide (rGO) in enhancing nanocomposite performance through novel modifications with inorganic materials, organic polymers, and biomolecules. Key insights into advanced modification techniques and their impact on functionality and durability are presented. The review also explores graphene-enabled electrochemical sensors that showed high sensitivity to phenolic compounds in water. Mechanisms accounting for the improved performance of these materials are discussed, along with associated challenges such as scalability, cost-effectiveness, and stability. Future directions are suggested, focusing on sustainable, intelligent coatings and thin-film devices for environmental applications. This work aims to guide researchers, industry professionals, and policymakers in leveraging graphene-based technologies to tackle global issues in corrosion prevention, marine ecology, and environmental monitoring.</p> 2024-12-11T00:00:00+00:00 Copyright (c) 2024
