Abstract

The synthesis of nanocomposites containing hydroxyapatite and graphene sheets has received much attention recently. Therefore, strategies that improve their properties will be useful. The aim of this study was to investigate the effect of diethylene glycol on the characteristics of hydroxyapatite-reduced graphene oxide powders synthesized by a hydrothermal method (180 oC, 5 h) and the nanocomposites obtained by spark plasma sintering (950 oC, 50 MPa). Graphene oxide, calcium nitrate tetrahydrate and diammonium hydrogenphosphate were used as precursors. The characterization methods included electron microscopy, X-ray diffraction, Raman spectroscopy, and indentation technique. Obtained results have shown that the presence of diethylene glycol

Abstract

In this study, the effect of the argon, nitrogen, and hydrogen gases on the final properties of the reduced graphene oxide- hydroxyapatite nanocomposites synthesized by gas injected hydrothermal method was investigated. Four samples were synthesized, which in the first sample the pressure was controlled by volume change at a constant concentration. In subsequent samples, the pressure inside the autoclave was adjusted by the injecting gases. The initial pressure of the injected gases was 10?bar and the final pressure considered was 25?bar. The synthesized powders were consolidated at 950??C and 2?MPa by spark plasma sintering method. The final samples were subjected to Vickers indentation analysis. The findings of this study indicate that th

Abstract

In this study, to achieve high transparency of magnesium aluminate spinel, the ready-to-sinter spinel (RSS) powder was sintered by spark plasma sintering (SPS). To prepare the RSS powder, LiF nanopowder was synthesized at diverse temperatures and concentrations on the spinel powder surface (0.7 wt %). The optimal temperature and concentration were achieved to be (60 ?C) and (200 g/l), respectively. Then, the spinel body was fabricated by SPS method. The XRD, BET, ICP, FESEM and TEM analyses were applied for the characterization of the prepared powder. Also, the results of TEM and XRD analysis confirmed the presence of the fluoride light element (LiF compound) on the spinel particles surface. Finally, the final strength and density of

Journal PapersBatteries , Volume 6 , Issue 1, 2020 March , {Pages 5 }

Abstract

This paper presents research on the synergistic effects of nickel molybdate and reduced graphene oxide as a nanocomposite for further development of energy storage systems. An enhancement in the electrochemical performance of supercapacitor electrodes occurs by synthesizing highly porous structures and achieving more surface area. In this work, a chemical precipitation technique was used to synthesize the NiMoO 4/3D-rGO nanocomposite in a starch media. Starch was used to develop the porosities of the nanostructure. A temperature of 350 C was applied to transform graphene oxide sheets to reduced graphene oxide and remove the starch to obtain the NiMoO 4/3D-rGO nanocomposite with porous structure. The X-ray diffraction pattern of the NiMoO 4

Journal PapersComposites Part B: Engineering , 2020 February 29, {Pages 107928 }

Abstract

In this study, we demonstrate enhanced mechanical properties of three-dimensional graphene/hydroxyapatite (3DG/HA) nanocomposites by employing the Taguchi method. The hydrothermal process time, the total pressure, the hydrothermal temperature, and the weight percent of graphene to the hydroxyapatite were considered as control parameters. The results showed that all parameters were effective in controlling the process. According to the findings, the hydrothermal temperature had the greatest effect on the results. The predicted strength fracture toughness is 2.08 ? 0.30 Mpa.m0.5, which is within the 90% confidence interval. Microscopic analysis confirmed the presence of graphene sheets with folding and wrinkling in the powders and indicat

Journal PapersMaterials Advances , Volume 1 , Issue 5, 2020 January , {Pages 1337-1346 }

Abstract

In this study, hydroxyapatite-reduced graphene oxide (HA-rGO) powders were first synthesized in situ using a hydrothermal method. These powders were then consolidated using a cold sintering method. The solvent used in this method was water + dimethylformamide + brushite which was added to the powders at different ratios. The sintered samples were then evaluated using X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, high-resolution transmission electron microscopy, and Vickers microindentation. The results of this study showed that the best conditions for the sintering of rGO-HA nanopowders were a temperature of 200 ?C, a holding time of >30 min, and a pressure of 500 MPa. The best mechanical properties were ac

Abstract

The Sr0.95Sm0.0125Dy0.0125□0.025Ti0.90Nb0.10O3?δ/ZrO2 composite was directly prepared through spark plasma sintering. This approach limited the grain growth and facilitated the achievement of a narrow grain size distribution due to fast sintering and ZrO2 effects. Thermal conductivity declined to 1.68 W m−1 K−1, which is the lowest among the reported values for micro-polycrystalline SrTiO3-based structures.

Journal PapersJournal of Nanotheranostics , Volume 1 , Issue 1, 2020 December , {Pages 2 }

Abstract

In order to investigate the effect of graphene nanoribbons on the final properties of hydroxyapatite-based nanocomposites, a solvothermal method was used at 180 C and 5 h for the synthesis of graphene nanoribbons–hydroxyapatite nanopowders by employing hydrogen gas injection. Calcium nitrate tetrahydrate and diammonium hydrogenphosphate were used as calcium and phosphate precursors, respectively. To synthesize the powders, a solvent containing diethylene glycol, anhydrous ethanol, dimethylformamide, and water was used. Graphene oxide nanoribbons were synthesized by chemical unzipping of carbon nanotubes under oxidative conditions. The synthesized powders were consolidated by spark plasma sintering methodat 950 C and a pressure of 50 MPa.

Journal PapersScientific Reports , Volume 10 , Issue 1, 2020 May 22, {Pages 13-Jan }

Abstract

In this study, we show the synthesis of reduced graphene oxide/hydroxyapatite (rGO/HA) composites using a hydrothermal autoclave with argon-15% hydrogen gas injection. This both increases the hydrothermal pressure and uses hydrogen as a reductive agent in the process. The synthesized powders were then consolidated with spark plasma sintering method. The analysis of the consolidated samples included Vickers Indentation technique and cell viability. The results showed that injected gases in the autoclave produced powders with a higher crystallinity compared to synthesis without the gases. Also, hydrogen gas led to increased reduction of GO. The microscopic analysis confirmed existing graphene sheets with folding and wrinkling in the powders a
