Abstract

The characteristic properties of Polyaniline (PANI) motivate the scientific community to develop PANI materials with enhanced properties and performances for many applications (e.g., supercapacitors, sensors, anticorrosion coatings…). In their attempts to improve the properties and performances of PANI, they have replaced the conventional polymerization medium or the conventional electrolytes with ionic liquids, which are considered “green solvents”. It was reported in the literature that ionic liquids generally positively impact the morphology and properties of PANI as compared to the conventional PANI. It has been agreed that nanostructured homogeneous morphology of PANI is obtained in ionic liquids, while agglomerated morphology is characteristic of PANI prepared in the conventional medium. Furthermore, the electrochemical performances of PANI synthesized in ionic liquids generally better than that of the conventional PANI. The ameliorations that occurred on the properties of PANI-ionic liquids have been attributed to bonding theories, detailed and discussed in this manuscript, between the imidazolium-based ionic liquids and PANI. Furthermore, the beneficial effects of non-covalent interactions between PANI chains and the ions of the ionic liquids, as well as between the ions of ionic liquids themselves, have been introduced. Finally, by understanding the bonding theories, researchers can tailor the properties of PANI by selecting convenient ionic liquids.

Structural and electrical characteristics of Zr-doped HfO₂ (HZO) thin films deposited by atomic layer deposition for RRAM applications

In this study, Zr-doped HfO₂ (HZO) based resistive random-access memory (RRAM) device were fabricated. The Hf:Zr (1:1) ratio in the HZO films were controlled by changing the HfO₂ and ZrO₂ cycle ratio during the atomic layer deposition (ALD) process. Next, we studied the structural and electrical properties of the Au/HZO/TiN RRAM device structure. The RRAM devices exhibits an excellent resistance ratio of the high resistance state (HRS) to the low resistance state (LRS) of ~10 3 A, and as well as good endurance (300 cycles) and retention (>10 3 s), respectively. Further, the device showed different conduction mechanism in LRS and HRS modes. The lower biased linear region is dominated by ohmic conductivity, whereas the higher biased nonlinear region is dominated by a space charge limited current conduction. This device is suitable for application in future high-density nonvolatile memory RRAM devices.

Electrochemical performance of Pr_0.6Sr_0.4Fe_0.8Co_0.2O₃−δ as potential cathode material for IT-SOFC

Solid oxide fuel cells (SOFCs) are renowned for being effective energy sources that have potential to influence how energy is developed in future. SOFCs operate at low temperatures provides different benefits for widespread commercialization. In the present study a perovskite material Pr_0.6 Sr_0.4 Fe_0.8Co_0.2 O₃−δ (PSFCo) was investigated as cathode for SOFC in intermediate temperature range. Glycine nitrate process was used for the preparation of the samples. PSFCo exhibited cubic structure having small particle size (100–200 nm). The electrical conductivity of the PSFCo was measured as function of temperature up to 850 ℃. The sample displayed maximum electrical conductivity of 370 Scm −1 at around 550–600 ℃. The polarization behavior of PSFCo was calculated by means of AC impedance with Sm 0.8 Ce 0.2 O 2 (SDC) as electrolyte. The value of area specific resistance (ASR) was calculated as 0.146 Ωcm 2 at 800 ℃ and 0.248 Ωcm 2 at 700 ℃.

Manganese and iron-doped yttrium borate as an excellent multifunctional inorganic material

Manganese and iron-doped π -YBO₃ have been synthesized using a modified epoxide-mediated gel method. The PXRD pattern evaluated the formation of the desired phase and the structural changes. EDS spectra determined the elemental analysis of undoped and doped samples. Raman spectra observed the stretching and bending modes of B-O bonds. The direct band gaps for doped samples were 1.47 and 2.07 eV, respectively, lower than the band gap value of 5.81 eV for π -YBO₃ . The green and blue indigo emission bands were observed in the photoluminescence spectra. Doped samples showed good magnetic properties as they are antiferromagnetic and ferromagnetic at low temperature (T = 5 K) M-H plot and SQUID measurement. An indigenously built Sawyer-Tower circuit is used to measure ferroelectric hysteresis. Photodegradation studies of RhB were conducted under UV-visible irradiation.

Effect of the welding procedure on the deformation of superposed welds of a low carbon steel

This study compared gas-metal arc welding (GMAW) and laser beam welding (LBW) for the superposed joining of two low-carbon steels. The motivation was to reduce the visible defects (notches) in the external part of one of the sheets. Both welding processes produced sound welds characterized by ferrite and pearlite; however, the notch disappeared when LBW was used. The hardness values of the fusion and heat-affected zones were similar for both processes, but the tensile strengths were very different. The shear tensile strengths of the LBW and GMAW were 415 and 84 MPa, respectively. Finite element analysis simulations indicated a more diffuse distribution of the von Mises stress throughout the welded component. The GMAW FEA model also presented a defect because of excessive heat transfer and residual stresses. In conclusion, LBW can replace GMAW in this particular case with improvements in appearance, productivity, and mechanical strength.

Effects of pyrolyzed Buxus sempervirens ingredient as micro and bio fillers on polystyrene: Spectroscopic characteristics

In this study, Buxus sempervirens leaf ingredient (LP) and the carbon (LC) and the ash (LA) were obtained, which are the bio-originated materials. Carbon and ash obtained from this natural plant were prepared by heating and pyrolysis for 2 h at 250 ℃ and 700 ℃, respectively. Then, the solution casting method was used to prepare the composites of these bio-additives with polystyrene. Next, the effects of the additives on diffuse reflectance spectroscopy (DRS) and X-ray diffraction (XRD) spectra of polystyrene were investigated. In addition, the additives led to noticeable changes in X-ray diffraction results, implying a change in the morphology of the polymer. All of these observations imply the uniform formation of the polystyrene (PS) composites with the micro and bio-fillers.
