AbstractThe epoxy resin-based nanocomposites have been used to overcome the drawback of epoxy resin such as brittle, low impact resistance, poor stress cracking and poor corrosion resistance in the aggressive environment by incorporating inorganic nanoparticles into the high cross-linked structure of epoxy resin. However, the main problem of these composites is the agglomeration of nanoparticles which influences the worst dispersion in the epoxy matrix and leads to poor properties of the composite. Therefore, this work aims to study the effect of nanoparticle additions, i.e. ZrO2 nanoparticle and SiO2 nanoparticle including waste glass powder (WGP) which is an alternative inorganic filler, on properties of the epoxy resin-based nanocomposite. The particle surface of each filler was also modified with 3-glycidoxypropyltrimethoxysilane (GTPMS) in order to achieve better dispersion in the disk-shaped bulk composites. The chemical property of modified fillers was characterized by Fourier transform infrared spectroscopy (FT-IR). The physical properties, mechanical properties, water absorption and corrosion resistance of all composites are then investigated. The results revealed that the incorporations of ZrO2, SiO2, and WGP with GPTMS surface modification into epoxy resin-based nanocomposite exhibit better performance in mechanical properties, water absorption and corrosion resistance than the unmodified surface of ZrO2, SiO2, and WGP additions. Although, both modified- and unmodified surfaces of fillers for the epoxy resin-based nanocomposites show improvement in all properties compared to the neat epoxy resin but the electrical properties of epoxy resin-based nanocomposites with unmodified fillers and GPTMS-modified fillers do not show a significant effect on any electrical properties.Keywords: Surface modificationGTPMSepoxy resinnanocomposites Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work is supported by National Research Council of Thailand (NRCT), Nanotechnology and Material Analytical Instrument Service Unit (NMIS), College of Materials Innovation and Technology and King Mongkut’s Institute of Technology Ladkrabang.

AbstractA composite of bacterial cellulose and titanate nanotubes (BC/TNT) was prepared for use as a stretchable motion sensor in smart and wearable electronics. The composite was characterized using various techniques such as UV-VIS-NIR spectroscopy, SEM, XRD, IR spectroscopy, and thermogravimetric analysis. It was found that the dielectric constant of BC/TNT was up to 2.6 times that of BC with similar loss tangent, indicating improved charge storage. The composite was also constructed into a Kirigami pattern for improved stretchability. With a tensile strain of 0.4%, the change in resistance relative to the original resistance (ΔR/R0) was found to be 5.7% and 6.9% for BC and BC/TNT, respectively, demonstrating improved sensing performance.Keywords: Wearable electronicsflexible sensorbacterial cellulosetitanate nanotubesKirigami Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was financially supported by King Mongkut’s Institute of Technology Ladkrabang (KMITL) under Grant No. KREF116501.

AbstractTriboelectric nanogenerators (TENG) with great performance and biodegradability are desired for the expansion of novel medical devices and wearable electronics. The present study aims at the preparation of natural silk in the form of silk fibroin (SF) film for utilization in TENG and further improving its output efficiency by embedding organic-piezoelectric gamma-glycine (γ-gly) amino acid to be a hybrid-organic piezoelectric/triboelectric nanogenerator (HO-P/TENG). The attenuated total reflectance infrared spectroscopy (ATR-IR) results demonstrated the N-H, C = O, and C-N bonding for SF and SF/γ-gly, confirming its dominant effect with a strong electron-donating tendency from those amino groups. The scanning electron microscope (SEM) and synchrotron radiation X-ray tomographic microscopy (SR-XTM) images show good dispersibility of incorporated γ-gly on the surface and also inside the SF matrix relating to its content to improve the electrical performance homogeneously. By fabricating the device in the vertical contact-separation mode, the present SF/γ-gly HO-P/TENG at 15 wt% provides the maximum output voltage (VOC) and current (ISC) of 81 V and 121 μA with a maximum output power (Pmax) of 205 μW at the external load resistance of 5 MΩ. This SF-based HO-P/TENG has the advantage of being cost-effective with simple fabrication, demonstrating great promise for practical uses.Keywords: Silk fibroinamino acidhybrid organic piezoelectric-triboelectric nanogenerator Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work of Thitirat Charoonsuk was funded by the Office of the Permanent Secretary, Ministry of Higher Education, Science, Research, and Innovation (OPS MHESI), Thailand Science Research and Innovation (TSRI), and Srinakharinwirot University under the Grant number RGNS 64-211.

The color of Fe2O3 and MnO2-doped waste glasses displayed yellow and purple, respectively, because of absorbance for Fe2O3 near 440 nm and 1,000 nm which homogeneous distribution of Fe3+ (440 nm: 6A1g(S) → 4T2g(G)) and Fe2+ (1,000 nm: 5T2g(D) → 5Eg(D)) ions in the glass matrices while MnO2 around 486 nm as absorption band is assigned to a single allowed 6A1g(S) → 4T1g(G) transition which arises from the Mn3+ ions (3d4 configuration) in octahedral symmetry. Moreover, the CIE L*a*b* for all glass samples were also investigated.

AbstractCerium bromide (CeBr3) scintillation crystal were studied and analyzed from the photon and electron response measurements. For photon response measurements, the radioactive source has been used for the energy range of 0.356 MeV ≤E≤ 1.332 MeV. The 137Cs source irradiated with gamma ray energy at 0.662 MeV was used for the electron response measurement using Compton coincidence technique. The variable angles (θ) would generate the gamma energies corresponding to a scattering angle of 30° to 120°. The results of number of photoelectron (Nphe) show responds to linear trends for photon and electron response. The light yield shows increase with increasing the photon and electron energy. The results showed the non-proportionality of photon response and electron response demonstrated good proportional properties of all energy ranges and as the result, the crystal is a promising candidate for gamma or X-rays detection.Keywords: Scintillation crystalnon-proportionalitylight yieldCeBr3 AcknowledgmentsThe authors would like to thank National Research Council of Thailand (NRCT) through the Research and Researchers for Industries (RRI) Ph.D. Program (NRCT5-RRI63015-P19) for funding this research.

AbstractThis research developed glass material from Perlite. The glasses chemical formula is 20Na2O:40B2O3:(40-X)Perlite:XBi2O3 where X are 0,5,10,15,20, and 25 W% by the melt quenching technique. Physical, optical, its radiation shielding abilities were studied by measuring density, refractive index, transmittance, mass attenuation coefficients, linear attenuation coefficients, and the half value layer (HVL). Densities and refractive indexes of glasses decreased as bismuth oxide (Bi2O3) concentration increased. Transmittance percentage from UV–Visible spectrophotometer showed the highest transmission at 15% concentration of Bi2O3. For radiation shielding properties, the linear attenuation coefficient and the mass attenuation coefficient calculated from WinXCom program showed increasing via added content Bi2O3. The HVL of 5 W% Bi2O3 doped glass is lower than that of concrete. The results of this research show that perlite glass has an ability for radiation shielding material.Keywords: Perliteradiation shieldingBi2O3 AcknowledgmentsThis study would like to express gratitude to Pibulwitthayai School, Thepsatri Rajabhat University, and Nakhon Pathom Rajabhat University for their assistance.Disclosure StatementNo potential conflict of interest was reported by the author(s).

AbstractSurface charge density is a key factor that greatly enhances the performance of a natural-based triboelectric nanogenerator (TENG), which is essential for future sustainable sensing and harvesting devices. This work introduced a conductive interlayer between a main frictional layer and electrode. This approach can suppress the charge recombination rate and improve the amount of charges produced during the triboelectrification process. Bacterial cellulose (BC) film was selected as a main frictional layer for the TENG. A conductive nanomaterial, i.e. silver flake, was incorporated into the BC film as an intermediate layer for enhancing TENG performance. As firstly reported, the maximum electrical outputs for the multi-layer BC structure could be found when using silver flake/BC composite (ratio 1:5) as an intermediate layer, which has 122 V and 8.2 µA of output voltage and current, respectively. This is higher than the output voltage and current of a single layer BC TENG by approximately 3 and 8 times, respectively. The maximum output power of ∼440 µW is achieved by connecting with a load resistor of ∼10 MΩ. This demonstrates an efficient strategy for designing a high performance energy harvester by adding an intermediate layer for the target of practical purposes in sustainable systems.Keywords: Bacterial cellulose paperconductive nanofillerIntermediate layerTriboelectric nanogeneratorPerformance AcknowledgmentsThe authors gratefully acknowledge Miss Sasithorn Supaket and Miss Sasiwimon Siripongaporn for their assistance in BC and BC composite synthesis.Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported financially by KMITL under Grant No. KREF116501.

摘要表面电荷密度是提高天然摩擦电纳米发电机(TENG)性能的关键因素，是未来可持续传感和收获装置的关键。这项工作在主摩擦层和电极之间引入了导电中间层。这种方法可以抑制电荷复合速率，提高摩擦电过程中产生的电荷量。选择细菌纤维素(BC)膜作为TENG的主要摩擦层。在BC薄膜中加入导电纳米材料银片作为中间层，以增强TENG性能。如前所述，当使用银片/BC复合材料(比例为1:5)作为中间层时，多层BC结构的最大电输出分别为122 V和8.2µA输出电压和电流。这比单层BC TENG的输出电压和电流分别高出约3倍和8倍。最大输出功率为~ 440µW，通过连接负载电阻~ 10 MΩ实现。这证明了通过在可持续系统中为实际目的添加中间层来设计高性能能量收集器的有效策略。关键词:细菌纤维素纸导电纳米填料;中间层;摩擦电纳米发电机;性能感谢Miss Sasithorn Supaket和Miss Sasiwimon Siripongaporn对BC和BC复合材料合成的帮助。披露声明作者未报告潜在的利益冲突。本研究由KMITL资助，批准号:KREF116501。S.

AbstractLead-free (1-x)BiFeO3-xBaTiO3 ceramics (abbreviated as BF-xBT), in a composition range of 0.23 ≤ x ≤ 0.33 mol%, were prepared by the conventional solid-state reaction method. The effect of x content on phase structure, microstructure, magnetic and electrical properties of BF-xBT ceramics is also investigated. With the incorporation of x content, the coexistence of rhombohedral and tetragonal phases was observed. Field emission scanning electron microscope (FESEM) micrographs revealed that the average grain size of BF-xBT ceramics first decreased and then increased with adding x content. The fracture surface of samples showed a mode of inter-granular fracture and intra-granular fracture. The ferroelectric properties were enhanced by adding x ≥ 0.29 mol% in the BF-xBT system. The dielectric and magnetic properties were improved with a maximum value are εr = 888,711, Mmax = 0.40 emu/g, Mr = 0.17 emu/g, and Hc = 3.7 kOe at x = 0.25 mol%Keywords: BiFeO3–BaTiO3multiferroic materialsmicrostructureferroelectric and magnetic properties Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported financially by The National Science, Research and Innovation Fund (NSRF) through Naresuan University (R2565B059).
