It is with great excitement to share our new research paper entitled "Multiscale study on the solid-liquid synergistic lubrication mechanism of graphite and liquid lubricant in polymer composites" by Carbon (Q1 journal in Multidisciplinary Materials Science, Impact factor: 10.5). This paper investigates the effects of graphite and poly α-olefin base oil (PAO) content and PAO/graphite ratio on mechanical and tribological properties of interpenetrating network (IPN)-polyurethane acrylate (PUA) composites, in combination with molecular dynamics (MD) simulations, first-principles calculations and chemical composition characterisation of the transfer film so that the synergistic mechanism of graphite and PAO at the friction interface is revealed. This provides a fundamental research platform for better understanding of solid-liquid synergistic lubrication mechanism in IPN-PUA composites Research Article Weblink: https://lnkd.in/gY4xvdiB #polymercomposites #graphite #lubrication #tribology #friction #modelling

Studying the Effect of Phosphogypsum Addition on Ceramic Membrane Properties https://lnkd.in/dbveq7U2 Abstract This study aimed to investigate the effects of phosphogypsum addition on ceramic membrane properties. In this regard, clay and phosphogypsum were characterized using FTIR and laser particle sizer. The ceramic paste was prepared by incorporating varying amounts of phosphogypsum (10 to 50%), followed by molding using a semidry-pressing process at 10 bars pressure and sintering temperature at 900°C. The raw materials and prepared membranes were analyzed using FTIR, laser particle size, contact angle, porosity, and mechanical strength to evaluate the properties of the resulting ceramic membranes. The study showed that as the amount of phosphogypsum increased from 10% to 50%, the membrane's hydrophilicity significantly increased, while its mechanical strength decreased by 35% and porosity increased by 26%. Moreover, the permeability of distilled water also showed a significant increase of 67% when the amount of phosphogypsum was increased from 10% to 50%.These observations suggest that phosphogypsum can significantly influence ceramic membrane properties, which may have implications for its use in various membrane applications. The findings of this research contribute to our understanding of the potential use of phosphogypsum as a valuable material for ceramic membrane production, with important implications for sustainable waste management practices. Future studies can focus on exploring the suitability of these ceramics for various applications and their environmental impact. Highlights: • Possibility of use of phosphogypsum as additive in ceramic membrane • Effects of phosphogypsum on ceramic membrane properties. • Adding of phosphogypsum leads to increased hydrophilicity, decreased mechanical strength, and increased porosity of ceramic membranes. • phosphogypsum has the potential to significantly affect ceramic membrane properties and its use in various membrane applications. Keywords: • Phosphogypsum • Ceramic membranes • Porosity • Hydrophilicity • Mechanical strength Journal: https://lnkd.in/dgnvtdte Issue: https://lnkd.in/dX62nRHe Article: https://lnkd.in/dm9i8MGc ETJ LinkedIn: https://lnkd.in/d_8SPqAt #Engineering_and_Technology_Journal #UOT #engineering #technology #etj

A new comprehensive review paper on hydrogen embrittlement. 👉 Free 50 days' access will expire soon. Download paper quickly: https://lnkd.in/dP44t9d8 "Hydrogen Embrittlement and Hydrogen-Induced Crack Initiation in Additively Manufactured Metals: A Critical Review on Mechanical and Cyclic Loading", by Alireza Behvar, Meysam Haghshenas, and Milos Djukic, International Journal of Hydrogen Energy, 58 (2024), pp. 1214-1239. Highlights: • Viewing hydrogen embrittlement (HE)'s impact on mechanical properties in additive manufacturing features its key roles. • Emphasizing the complexity of HE in AM alloys, urging ongoing investigations in hydrogen-rich environments. • Examining AM metals reveals varying HE behavior by alloy (e.g., titanium, nickel superalloys, austenitic stainless steel). • Assessing the microstructure's crucial role in quantifying HE in AM metals. • Exploring innovative solutions for HE in AM alloys in hydrogen-rich environments (e.g., aerospace). it is necessary to carefully check correlations between various AM metal microstructures obtained using different AM techniques and the activity of multiple HE mechanisms. This also includes the preconditions for the activation and synergy of the multiple active HE mechanisms in AM metals and the predominance of one of them (HELP/other plasticity-mediated mechanism or HEDE). The sound basis for advanced experiments represents a well-established and vastly confirmed unified HELP+HEDE model by Djukic et al. for the synergy of HE mechanisms. This model defines characteristic fracture modes and activity (dominance) of HELP, HEDE, or HELP + HEDE, depending on hydrogen concentration and specific microstructural characteristics.

🚀 Exciting News! Our research paper, "Effect of second-phase precipitates on deformation microstructure in AA2024 (Al–Cu–Mg): dislocation substructures and stored energy," is now published in the Journal of Materials Science 🎓📚! ✨ This is the final piece of my thesis puzzle, and it marks the end of an incredible journey! (Even though there are some more material to be published). The study investigates how the precipitation state affects the deformation microstructure in the widely used AA2024 aluminum alloy during cold rolling. 🔬 By combining advanced techniques like transmission electron microscopy (TEM), electron backscatter diffraction (EBSD), and dark-field X-ray microscopy (DFXM), we found some differences in microstructure formation depending on whether the precipitates were shearable or non-shearable 💡. 🙌 A special shout-out to my co-authors: CAN YILDIRIM, who made it possible for us to use the DFXM installation at ESRF - The European Synchrotron and my thesis supervisors Mohamed SENNOUR, Vladimir Esin and Charbel Moussa. I’m thrilled to share this work and excited to see how it can contribute to the field of materials science! 🔍🔩 👉 Link to the open access publication: https://lnkd.in/edchSbsA #MaterialsScience #AluminiumAlloys #DeformationMechanisms #Microscopy #Research #PhDJourney #Engineering
