AbstractFor BaO based on steel slag glass system (BaSSG) in chemical composition (50-x)B2O3: 20steel slag: 20Na2O: 10CaO: xBaO (x = 0, 5, 10, 15, 20, 25 wt%) were prepared by melt quenching technique at 1,200 °C and investigated optical, X/γ-rays, fast and thermal neutrons shielding properties. The optical properties were measured and explained on transmission (T%) value. The X/γ-rays shielding properties were experimented with and explained on mass attenuation coefficients (µm) for X-rays which were measured using a high-frequency digital X-rays machine while γ-rays were measured using the narrow beam transmission method. In addition, half value layer (HVL), mean free path (MFP) and transmission factor (TF) values were evaluated and discussed. Also, fast and thermal neutron shielding properties of BaSSG have been evaluated and discussed. The results found that the BaSSG6 glass sample had the highest T% and µm values, while HVL, MFP and TF were the lowest. These results indicated that the BaSSG6 glass sample offers excellent X/γ-rays and fast neutron shielding compared to other samples. Whereas the BaSSG1 glass sample provided superb thermal neutron shielding. These reflected that the BaSSG glass system had the potential to develop transparent and Pb-free shielding material.Keywords: Steel slag glassX/γ-rays shieldingfast and thermal neutrons Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis research is financially supported by Thailand Science Research and Innovation (TSRI) National Science, Research and Innovation Fund (NSRF) (Fiscal Year 2022).

Abstract Lead-free Ba(Ti0.91Sn0.09)1-xVxO3 (BTSV, x = 0, 0.005,0.010, 0.015, and 0.020) ceramics were prepared by the conventional solid-state sintering method with a calcination temperature of 1200 °C for 2 h and a sintering temperature between 1350 °C and 1400 °C for 4 h. The effect of vanadium (V) doping on the phase formation, microstructure and electrical properties of the ceramics was investigated. X-ray diffraction (XRD) measurements revealed that the ceramics with x = 0 and 0.005 had pure perovskite structures with no detectable impurity, while the ceramics with x ≥ 0.010 exhibited perovskite structures and had secondary impurity phases. Coexisting orthorhombic and tetragonal phases were observed and the Rietveld refinement analysis suggested that the tetragonal phase increased with increased V5+ substitution. When x increased from 0 to 0.010, the average grain size increased from 47 to 62 µm and then dropped, while the density (ρ) decreased from 5.98 to 5.64 g/cm3 when x increased. Furthermore, the BTSV ceramics exhibited increased porosity, Curie temperatures (T C ∼ 42 °C to 52 °C) and coercive field (E c), while the dielectric constant at the Curie temperature (εC) and the remnant polarization (P r) of the ceramics decreased (∼18023 to 6110 and ∼7.42 to 4.88 µC/cm2, respectively) when V5+ doping increased.

AbstractBarium strontium titanate (Ba0.8Sr0.2TiO3; BST) ceramics, were prepared by the hybrid method between Solid-state reaction (SSR) and Sol-gel methods (SG) in a ratio of 1:0.1–1:0.5. The BST powder was successfully calcined at 850 °C for 2 h. This temperature is much lower than the calcination temperatures of the SSR method. The BST ceramics were sintered between 1150 and 1450 °C. All samples showed the pure perovskite structure corresponding to JCPDS no. 34-0411. The optimum sintering temperature was observed from the samples sintered at 1450 °C for 4 h, indicating a density of 5.26 g/cm3, dielectric constant of 7018, and ferroelectric properties: (Pmax = 13.8 μC/cm2, Pr = 2.5 μC/cm2 and Ec = 2.3 kV/cm at 30 kV/cm).Keywords: Phase transitionmicrostructureferroelectrichybrid method AcknowledgmentsThe authors thank the Program of Physics, Faculty of Science and Technology, Pibulsongkram Rajabhat University for supporting facilities.Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis research was funded by Pibulsongkram Rajabhat University, grant number RDI-2-61-14.

AbstractDue to its adaptability in scaling up, a redox flow battery (RFB) is seen to be one of the finest options for large-scale electrical backup systems. As a result, it is feasible to create RFB systems that are both cost and performance effective. Recently, a zinc-manganese RFB that relies on Zn(s)/Zn2+(aq) and Mn2+(aq)/MnO2 redox couples has gained attention since both zinc and manganese are cheap, abundant, and eco-friendly. However, the reversibility of Mn2+(aq)/MnO2 at the positive electrode is limited by the formation of Mn3+ species upon charge/discharge (CD) cycling, resulting in severe capacity fading. Herein, this study examines the use of reducing agents as electrolyte additives to enhance the reversibility of the Mn2+(aq)/MnO2 reaction. Experimental results indicate that sulfuric acid and oxalic acid as additives can significantly improve the reversibility of the Mn2+(aq)/MnO2 reaction and the cycling stability of zinc-manganese RFBs. The acetate-based system demonstrates better reversible reaction than the sulfate-based system having more than 100 CD cycles at a current density of 10 mA/cm2. Coulombic efficiency (CE) is also seen to be higher than 90%. Overall, results lead to increased efficiency and cycling stability for zinc-manganese RFBs.Keywords: Zinc-manganese flow batteryelectrolyte additivemanganese oxide dissolution/depositionMn2+(aq)/MnO2 AcknowledgmentsThe Program Management Unit for Human Resources & Institutional Development, Research and Innovation (B16F640166), the Energy Storage Cluster, Chulalongkorn University, and Beamline 5.2 at Synchrotron Light Research Institute (SLRI) are acknowledged.Disclosure StatementNo potential conflict of interest was reported by the author(s).

AbstractThe radiation shielding and elastic moduli properties of (60–x)TeO2–30P2O5–xBi2O3 (x increased from 10–50 mol% in 10 mol% increments) glass series have been discussed. The radiation shielding quantities such as mass attenuation coefficient (µm), effective atomic numbers (Zeff), half value layer (HVL) and mean free path (MFP) were calculated using Phy–X/PSD program at energies ranging from 1 keV–100 GeV while exposure and energy absorption buildup factors (EBF and EABF) were evaluated using geometric progression (G–P) fitting method at energies ranging 0.015–15 MeV for penetration depths (PD) until 40 mean free path (mfp). In addition, the density and elastic moduli were estimated. The results found that the TPB5 glass sample having the largest content of Bi2O3 possessed the highest density and excellent radiation shielding properties. This reflected that replacing TeO2 with Bi2O3 improved effective radiation shielding. In addition, the MFP for glass series were lower than the hematite-serpentine concrete. It indicated that this glass series are photon shielding better than the hematite-serpentine concrete. Whereas, this sample had the lowest elastic moduli. These results indicated that Bi2O3, a network modifier, has broken glass network bonds and formed non–bridging oxygen (NBOs) which affects the elastic moduli of the glass system.Keywords: Radiation shieldingelastic moduliglass AcknowledgmentsThis research is financially supported by Thailand Science Research and Innovation (TSRI) National Science, Research and Innovation Fund (NSRF) (Fiscal Year 2022)Disclosure StatementNo potential conflict of interest was reported by the author(s).

AbstractThe conventional melt-quenching synthesis was used to produce a series of thermoelectric glasses with the compositions 20Li2O-40V2O5-20B2O3-20ZnO (LVBZ) with Bi2Te3 doping as a percentage is 0, 5, 10, 15, 20, and 25 by weight. To discover the potential of thermoelectric glass, a comprehensive study was conducted on a series of samples using a combination of methods for analyzing both their structural and electrical properties. The structure exhibits the findings of the X-ray diffraction (XRD) analysis compositional investigation. It was discovered that the intensity within the LiV3O8 phase decreased with increasing dopant Bi2Te3 concentration, which produced an impact on the thermoelectric properties. The density value highest at 25 wt% doping and was 3.17 g/cm3. Furthermore, the thermoelectric properties of the samples were examined using ZEM-3 series instruments. The behavior of the semiconductor material is represented by the continual decrease in electrical resistivity value. The N-type thermoelectric material classification is represented by the verified Seebeck coefficient value. Out of the samples tested, the LVBZ with 15% Bi2Te3 doping by weight demonstrated the highest electrical performance in this series, with a power factor of 0.07 µW/mK2 at 668 K. The examined power factor values lead to the conclusion that the result of electrical conductivity increases with testing temperature.Keywords: Wordmelt-quenchingthermoelectric glasspower factor AcknowledgmentsThe authors would like to thanks Thermoelectric Research Laboratory, Center of Excellence on Alternative Energy, Research and Development Institution, Sakon Nakhon Rajabhat University for thermoelectric properties measurements.

AbstractIn this work, nanocomposites between the epoxy resin and barium titanate (BT) were prepared in order to use as flexible energy storage devices. The epoxy resin and BT phase were homogeneously mixed and cast into a disk shape. Phase formation and chemical properties of these nanocomposites were identified via XRD and FTIR methods, respectively. Frequency dependence of dielectric properties for all samples was measured by LCR meter. The polarization hysteresis loops were also investigated in order to calculate the energy density of materials. From the results, it was found that the dielectric constant and loss of these nanocomposites are independent of frequency and the εr and tanδ values tend to increase with increasing BT amount. Moreover, after adding 50% of BT into the system, the energy density of nanocomposites is increased by five times compared with the pure epoxy resin while the energy loss density sharply decreases. The dielectric properties and the energy density of BT/epoxy resin nanocomposites change with BT content and strongly depend on porosity and the distribution of BT nanoparticles.Keywords: Epoxy resinbarium titanatenanocompositeenergy storage AcknowledgmentsThe authors acknowledge the facilities, and technical assistance from Nanotechnology and Materials Analytical Instrument Service Unit (NMIS) of College of Materials Innovation and Technology, King Mongkut Institute of Technology Ladkrabang.Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis project is funded by National Research Council of Thailand (NRCT).

AbstractNa3+x[(Zr/Cr)x(Sc/Ti)2-x(PO4)3] glass-ceramic material compositions containing NASICON-type crystalline phases might be a good candidate as an efficient electrolyte exclusively for Na-ion batteries. All-solid-state Na-ion full cells are designed with the three-layered pellets (NaCo0.7(VO)0.3PO4/Na3.5Zr0.5Sc1.5(PO4)3 (NZSP) and Na3.5Cr0.5Ti1.5(PO4)3) (NCTP)/Na-metal foil). The electrical conductivity of the NZSPglass-ceramic powder sample achieves to be highest (9.47 × 10−04 S/cm) due to its lower grain boundary resistance (Rgb) as observed in SEM images and also exhibits best electrochemical stability against conductivity when the samples kept in ambient air for 60 d. The charge/discharge capacities for the initial cycle are 75/69 and 60/53 mAhg−1 to both NZSP and NCTP of two full cells, respectively. However, discharge capacities are boosted up for both these cells without much loss in coulombic efficiency even after 10 cycles.Keywords: Sodium-ion batteryglass-ceramic solid electrolyteNASICON phasecyclic performance AcknowledgmentsThe authors wish to thank Dr. Tanusrivathava, Scientist, DMRL Hyderabad, for helping us to carry out SEM images.Disclosure StatementNo potential conflict of interest was reported by the author(s).

AbstractThis study focused on the rare-earth hetero-valent substituted perovskite BaMO3 (M = Ce, Pr and Tb) which expected to show magnetoelectric response. In general, diamagnetic feature is presented in the 4f 0 BaCeO3 system down to 2 K which is chosen as a reference in the study while BaPrO3 (4f 1) and BaTbO3 (4f 7) display antiferromagnetic phase transition at TN = 11.7 and 33.2 K, respectively, measured by MPMS magnetometer. At high oxygen partial pressure and donor ion-substitution (Nb5+), the BaMO3 systems demonstrate a similar defect chemistry to titanate perovskite which compensated by Ba-vacancy. Dielectric relaxation is detected for the doublet (BaPrO3 and BaTbO3) at the antiferromagnetic phase transition region. In order to examine the magnetoelectric response, the 8 Tesla of magnetic field is applied to the samples during the dielectric measurement. BaTbO3 shows a modest magnetoelectric response around 0.2% at the antiferromagnetic phase transition while that of BaPrO3 is silent. The activation energies derived from Arrhenius equation are reported to be in the range of 0.2 − 0.6 eV.Keywords: Rare-earth perovskitepoint defectmagnetoelectric AcknowledgmentsW’e would like to thank our colleagues, Dr. Usa Sukkha, for the helpful support in this research.Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported financially by KMITL under Grant No. KREF116501.

AbstractThis research aims to develop flexible semiconductors for triboelectric nanogenerator (TENG) applications.

The semiconductors were prepared to be a composite film with alginate. The structure, morphology, and purity of the N- and P-type semiconductors were characterized using X-Ray diffraction and scanning electron microscopy techniques. Through the optical characterization, the N-type semiconductor showed the calculated energy band gap of 2.80 eV, while the P-type semiconductor was 1.90 eV. The P–N junction property of prepared samples was confirmed using a nonlinear current–voltage characteristic. After that, two flexible semiconductors were frictional paired for TENG.

摘要本研究旨在开发用于摩擦电纳米发电机(TENG)的柔性半导体。分别制备了n型和p型半导体的石墨化氮化碳(g-C3N4)和氧化铜(Cu2O)样品粉末。将半导体与海藻酸盐制备成复合薄膜。利用x射线衍射和扫描电镜技术对N型和p型半导体的结构、形态和纯度进行了表征。通过光学表征，n型半导体的计算能带隙为2.80 eV, p型半导体的计算能带隙为1.90 eV。利用非线性电流-电压特性证实了所制备样品的pn结性质。然后，将两个柔性半导体摩擦配对用于TENG。通过垂直触点分离模式，基于P-N结的TENG在10 MΩ时的最大输出电压和电流分别为3.90 V和0.44µa，最大输出功率为0.35µW。综上所述，本工作实现了柔性P型和n型半导体的制备。在TENG结构中验证了获取机械能的可行性。这一想法对于使用新概念的柔性收获/传感设备的未来发展至关重要。关键词:p型半导体- n型半导体- n结摩擦纳米发电机披露声明作者未报告潜在利益冲突。本研究由KMITL资助，授权号为KREF156601。Supakarn wora的工作得到了蒙古库特国王理工学院(KMITL)科学学院的资助，资助项目为:RA 2565 - m - 001 /助教。S.
