Fe3O4 nanoparticles were generated by chemical precipitation. Oleic acid covered the nanoparticles as a surfactant performer. X-ray diffraction (XRD) was used to investigate the fine grains sample, and scanning electron microscope (SEM) images were used for observing the nanoparticles’ geometry. The vibrating sample magnetometer (VSM) was also used to examine the magnetic characteristic of the nanoparticles. Chemical bonds were determined by using Fourier transform infrared spectroscopy (FTIR). As a result, the hysteresis loop characterized the magnetic nanoparticles. Magnetite nanoparticles are regarded as a soft magnetic material due to their low coercivity. XRD diagrams show the presence of powerful peaks in the orientations of crystal surfaces of the spinel form of the nanoparticles. The result showed that nanoparticles were nearly spherical. The average dimensions of the nanoparticles were estimated by Scherrer approximation. The mean particle dimensions were 11 nm (chemical mixer) and 13 nm (magnet mixer). SEM images verified the spherical shape of the nanoparticles, and FTIR confirmed the constitution of Fe-O bonds and validated the spinel ferrites configuration.","PeriodicalId":14985,"journal":{"name":"Journal of Applied Biomaterials & Functional Materials","volume":"40 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84474353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reduction atmosphere was removed when the temperature was down to 800oC. The XRD pattern showed that only the CaMgSi2O6 phase was observed in synthesized 0.025Eu2+-doped CaMgSi2O6 powder. Room-temperature photoluminescence excitation (PLE) and photoluminescence (PL) spectra of Eu-CaMgSi2O6 phosphors were recorded by using the Hitachi F-4500 fluorescence spectrophotometer at wavelength ranges of 200–430 and 350–600 nm, respectively. A new important finding is that the synthesized Eu-CaMgSi2O6 phosphor has three important PLE wavelengths. Therefore, Eu-CaMgSi2O6 phosphors are measured from 25oC (room temperature) to 200oC under three different PLE wavelengths to find the effect of temperature on the variations of maximum photoluminescence intensities (PLmax). All the PL spectra show that only one emission band with a central wavelength of 449 nm is found, which is independent of the PLE wavelengths and is caused by the transition of 4f7 → 4f65d1. Another important finding is that the different PLE wavelengths have an apparent effect on the PLmax value of the Eu-CaMgSi2O6 phosphor. Finally, the decay-time curves of Eu-CaMgSi2O6 phosphor under three PLE wavelengths are also investigated.","PeriodicalId":14985,"journal":{"name":"Journal of Applied Biomaterials & Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88932719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting material was then investigated as electrode materials for supercapacitors. [Imi][HSO4] was prepared via a one-step acid-base reaction, and its structure was confirmed by 1H NMR. [Imi][HSO4] displayed full miscibility with water owing to the charge density distribution of its ions. Furthermore, the binary mixture [Imi][HSO4]/water is highly acid (e.g. pH ~ 0.1 for [Imi][HSO4]/water in a weight ratio of 70/30). As the polymerization medium for PANI/PIL, [Imi][HSO4] plays the role of a soft template agent and induces nanostructured PANI formation with fibrillar morphology (as shown by SEM images) without affecting the typical structure of PANI (as confirmed by FT-IR analysis). Furthermore, PANI/PIL was obtained in emeraldine salt form without any undesirable byproduct. Moreover, the electrical conductivity was seven times superior to that of the conventional PANI (i.e. PANI/HCl) when measured by the four-probe technique of PANI/PIL (~ 21.8 S/cm). This improvement in the PANI/PIL’s electrical conductivity of as well as the fibrillar morphology of PANI/PIL positively influences its electrochemical performances and highlights the suitability of [Imi][HSO4] as a polymerization medium for PANI material.","PeriodicalId":14985,"journal":{"name":"Journal of Applied Biomaterials & Functional Materials","volume":"15 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87269246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A stable and satisfactory aesthetic result demands a meticulous procedure, which involves many clinical and laboratory steps. The purpose of this article is to present a case of aesthetic reconstruction in the anterior region with a successful 14-year recall. A 40-year-old female patient came to the dental clinic complaining about her smile appearance. Lithium disilicate glass-ceramic full-coverage restorations for the six upper anterior teeth were the selected treatment plan for this case. The key to this successful result was the used therapeutic methodology, where the characteristics of the provisional restorations were copied to the final restorations. In this article, the therapeutic methodology is presented step by step and all the clinical and laboratory steps are explained thoroughly. The patient has visited the dental clinic annually as arecall visit. The final result from the 14-year recall visit revealed that the aesthetic result was stable, the restorations were intact and there were no signs of gingival infection or dental decay. Consequently, the presented therapeutic methodology leads to a successful and long-term result.","PeriodicalId":14985,"journal":{"name":"Journal of Applied Biomaterials & Functional Materials","volume":"11 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86663065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the response of the electronic structure of chiral and nonchiral SWNTs (8,7), (9,6), (10,5), (7,7), (11,0), (12,0), and (13,0) to twisting and axial tension modes by using the symmetrized linear augmented cylindrical wave technique. We showed that perturbations of the band structures depend on a “family” index p = (n1 − n2)mod 3 (where p = −1, 0 or 1). Twisting the semiconducting (8,7) tubule with p = 1 in the direction of the screw axis is accompanied by the large broadening of minimum gap E11 and narrowing of the second gap E22, while these gaps drastically change in the tubule (10,5) with p = −1. In these tubules, changing the direction of twisting leads to the reversal in direction of the gap shifts. Regardless of the twisting direction, in metallic (7,7) and quasi-metallic (9,6) SWNTs with p = 0, the E11 gap rapidly increases from 0.0 and 0.035 eV to about 1 eV. When twisting the zigzag tubules (13,0) p = 1 and (11,0) p = −1, the gaps E11 equal to about 0.8 eV increase and decrease by several hundredths of eV. On the contrary, the compression and extension of these tubules cause a sharp change in their band structure with approximately a twofold change in the gaps E11 and E22 and inversion in the sequence of the boundary bands. The similar deformation of the armchair nanotube (7,7) has practically no effect on its electronic levels. In the case of zigzag (12,0) p = 0 SWNT, all deformation modes transform the quasi-metallic tubule into the semiconductor.","PeriodicalId":14985,"journal":{"name":"Journal of Applied Biomaterials & Functional Materials","volume":"62 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85782763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
