    Nanostructuring Polyaniline Using Non-Substituted Imidazolium-Based Ionic liquid as Polymerization Medium Enabling Faster Supercapacitor Operation

    by Fatima Al Zohbi, Fouad Ghamouss, Bruno Schmaltz, Mohamed Abarbri, Khalil Cherry, Mohamad fadel Tabcheh and François Tran Van*
    AFM 2022, Vol 2, Issue 3, 1-11, https://doi.org/10.35745/afm2022v02.03.0001 - Published on September 30, 2022

    Abstract

    Non-substituted imidazolium-based protic ionic liquid, namely imidazolium hydrogen sulfate [Imi][HSO4], has been investigated as a polymerization medium for PANI (designated as PANI/PIL). 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...

    Clinical Significance of Accurate Transfer of Provisional Resin-Based to Permanent Lithium Disilicate Glass Ceramic Dental Restorations

    by Evangelos Ximinis, Maria Tsiafitsa, Olga Naka and Dimitrios Dionysopoulos*
    AFM 2022, Vol 2, Issue 3, 12-23, https://doi.org/10.35745/afm2022v02.03.0002 - Published on September 30, 2022

    Abstract

    Smile reconstruction is, yet, a challenging procedure for dental practitioners. 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 t...

    Study on Preparing β-Ga2O3 Films with Temperature-Controlled Buffer Layer by RF Magnetron Sputtering

    by Yi Liu, Tinglin He and Sufen Wei*
    AFM 2022, Vol 2, Issue 3, 24-29, https://doi.org/10.35745/afm2022v02.03.0003 - Published on September 30, 2022

    Abstract

    β-Ga2O3 thin films were prepared on (0006) sapphire substrates by RF magnetron sputtering. Under the conditions of sputtering power of 80 W, time of 10 min, and total flow rate of 40 sccm in oxygen and argon atmosphere (2.5 % oxygen ratio). Different preparation temperatures were used to conduct layering by temperature modulation. A homogenous β-Ga2O3 buffer layer was grown first, and then the second β-Ga2O3 film was grown on top of it. When the stratified sputtering of different temperature com...

    Temperature-dependent Photoluminescence Properties of Eu2+-doped CaMgSi2O6 Phosphors

    by Tung-Lung Wu, Guoxiang Peng, Wei-Ren Zhang and Cheng-Fu Yang*
    AFM 2022, Vol 2, Issue 3, 30-36, https://doi.org/10.35745/afm2022v02.03.0004 - Published on September 30, 2022

    Abstract

    The solid-state reaction method was used to synthesize 0.025Eu2+-doped CaMgSi2O6 (Eu-CaMgSi2O6) powder in the reduction atmosphere of 5% H2 + 95% N2 at 1300oC with a duration of 4 h. 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 recorde...

    Effect of Agitation Methods on Characteristics of Iron Ferrite Nanoparticles Synthesized by Co-Precipitation Process

    by Hamid Reza Dehghanpour*, Parviz Parvin, Aryan Younesi and Monireh Gilaki
    AFM 2022, Vol 2, Issue 3, 37-41, https://doi.org/10.35745/afm2022v02.03.0005 - Published on September 30, 2022

    Abstract

    To assess the result of the stirring process on the Fe3O4 nanoparticles' properties, two types of stirrings (mechanical and magnetic) were compared. 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 ...

    Novel Schiff Base Co(II) Complexes: Potential Biological Applications

    by Arumugam Parasuraman Arumugam , Govindan Elango and Selvam Guhanathan *
    AFM 2022, Vol 2, Issue 3, 42-50, https://doi.org/10.35745/afm2022v02.03.0006 - Published on September 30, 2022

    Abstract

    Cobalt (Co) complexes with the N2O2 category have been created synthetically by the reaction of salicylaldehyde / 3,4-diamino benzophenone with acetylacetone and glutaric anhydride respectively. The ligands and individual Cobalt (II) complexes were recognized through spectroscopical data (Fourier Transform Infrared, Ultra Violet-visible, proton and carbon-13 NMR, & Mass). Non-electrolytic in nature of the complex found from their molar conductivities (Ω-1cm2mol-1) in DMSO of 10-3M solution. The ...
