In this paper, silver (Ag) nanoparticles were synthesized by utilizing an aqueous extract of fresh leaves Chenopodium murale which is considered a cost-effective and eco-friendly approach. The sol-gel technique was used to syntheses TiO2 different methods characterize the (Ag TiO2) including UV–Vis spectroscopy, XRD, TEM. Also, new nanocomposites prepared using solution casting method. films characterized analytical methods. absorption peak shown UV–visible spectrum around 430 nm. crystalline average size Ag NPs 20 nm while 15 as displayed XRD pattern. Meanwhile, degree amorphicity Cs/PEO blend increased result adding NPs. It evident through FTIR spectroscopy that there interaction between functional groups polymer Ag/TiO2 nanofiller. addition, increase mechanical properties such Young's modulus, elongation, tensile strength with increasing content. clear impedance spectroscopic study iconic conductivity improved addition into system. highest log −9.34 S cm−1 at Cs/PEO/0.3%Ag/0.8%TiO2. also from results antibacterial activity pure doping blend. index (%) sample + (0.3%) (0.8%) E. coli, S. aureus, C.

Mechanics of Advanced Materials and Structures, Год журнала: 2023, Номер 31(19), С. 4755 - 4772

Опубликована: Май 17, 2023

The present study is done to perform the optimal design of structural components buildings against unwanted wind load exerted on their outer face. To this end, case research wall made a one-floor building modeled as rectangular plate with only one free edge and three clamped ones. It assumed that sandwich whose core auxetic material dace-sheets are reinforced nanoparticles graphene platelets (GPL). Differential equations governing system's motion obtained within background plate's shear-deformation theories. stability analysis performed based application artificial intelligence (AI) methods optimized an innovative optimization approach gain high level accuracy. determine information system at train points, differential quadrature (DQA) applied solver motion. accuracy used in paper examined verified by comparing results those acquired articles published previously. provide very useful about response lightweight through AI-based solutions.

The effects of nano-additives on the mechanical, impact, vibration, and buckling/post-buckling properties of composites: A review

Journal of Materials Research and Technology, Год журнала: 2023, Номер 24, С. 7570 - 7598

Опубликована: Май 1, 2023

This study presents a review of the effect nano-additives in improving mechanical properties composites. Nano-additives added to composites, also termed nanocomposites, have promising applications aerospace, medical, biomedical, automotive, and military. The nanoparticles alter either surface, bulk, or both, depending upon process, dramatically change thermal conductivity, tensile strength, flexural fatigue impact resistance, vibration buckling, post-buckling, surface modification, application machine learning as well optimization methods nanocomposite materials. Such transformations composite materials are extensively studied by researchers positive implications successfully deployed various applications. Interestingly, recent findings revealed that weak chemical bonding between fiber matrix phase is main reason for delamination, however, addition nanoparticles, chances delamination reduced even under excessive loading. Graphene multi-walled carbon nanotubes (MWCNTs) most excessively reported nanomaterials enhancing behavior energy absorption capacity, decreasing adverse effects due porosity within structure. Also, techniques showed be way further improve while reducing total cost fabrication process predicting providing optimum characteristics with acceptable accuracy compared realistic conditions.
