background: flexural strength of prosthesis made with dental composite resin materials plays an important role in their survival. the aim of this study was investigating the effect of nanoclay fillers and poly (methyl methacrylate)-grafted (pmma-grafted) nanoclay fillers loading on the flexural strength of fiber-reinforced composites (frcs). materials and methods: standard frc bars (2 × 2 × 25 ...

In this work, we used density functional theory (DFT) and linear response time-dependent DFT (LR-TDDFT) to investigate the stability, electronic structure, and optical properties of Au-doped [Ag29-xAux(BDT)12(TPP)4]3- nanoclusters (BDT: 1,3-benzenedithiol; TPP triphenylphosphine) with x = 0-5. The aim of this work is to shed light on the most favorable doped structures by comparing our results ...

This paper describes a reliable and sensitive method for sensing dissolved acetone using doped nanomaterials. Large-scale synthesis of ZnO nanorods (NRs) doped with Co3O4 was accomplished by a solvothermal method at low temperature. The doped NRs were characterized in terms of their morphological, structural, and optical properties by using field-emission scanning electron microscopy coupled wi...

Due to potential applications of semiconductor transition doped nanostructure materials and the important advantages of synthesis in cost-effective and environmental concerns, a significant effort has been consummated for improvement of Ni-doped SnO(2) nanomaterials using hydrothermal technique at room conditions. The structural and optical properties of the low-dimensional (average diameter, 5...

Due to their biodegradability, affordability, low density, and numerous other benefits, natural fiber polymer composites are preferable conventional GFRP in maritime applications. However, when exposed moisture, mechanical qualities deteriorate. A significant agricultural waste called pineapple leaf (PALF) can be employed as reinforcement epoxy matrices. Improved interfacial bonding between pha...

The current study’s objective is to investigate the impact of nanoclay on tensile and wear properties glass fiber-epoxy-nanoclay ternary nanocomposite. Three types composites are produced by hand lay-up process compression molding. Tensile tests executed according ASTM standards. findings disclosed that enhanced causes for failure under load revealed SEM micrographs. Response surface methodolog...

Hammada scoparia (Pomel) is a powerful plant with important biological properties. In this study, we report on the green synthesis of silver-doped nickel and copper nanoparticles (NPs) in presence H. leaf extract using self-propagating sol–gel autocombustion process. The synthesized NiO, CuO, Ag-NiO, Ag-CuO NPs were characterized Fourier transform infrared spectroscopy (FTIR) X-ray diffraction ...

Photocatalysts produce free radicals upon receiving light energy; thus, they possess antibacterial properties. Silver (Ag) is an antibacterial material that disrupts bacterial physiology. Our previous study reported that the high antibacterial property of silver nanoparticles on the surfaces of visible light-responsive nitrogen-doped TiO2 photocatalysts [TiO2(N)] could be further enhanced by vi...
