Thermal wear comfort for workwear clothing plays a vital role in maintaining comfortable water- and moisture-vapor-permeable properties while wearing clothing. In particular, thermal wear comfort measured using a thermal manikin is required in the protective workwear clothing market because their use provides objective data concerning the actual wearing performance of the clothing. This paper investigated the thermal wear comfort properties of various ceramic-embedded composite fabrics for workwear clothing worn in gas and oil industries produced from new schemes. The thermal insulation rate (Clo value) of Al2O3(Aluminum oxide)/graphite, ZnO(zinc oxide)/ZrC(zirconium carbide) and ZnO/ATO(antimony tin oxide)-embedded clothing was greater (25.5, 24.7 and 16.9%, respectively) than that of regular clothing (control), which was in accordance with the results (15.0, 13.8 and 11.3% higher, respectively) of the heat retention rate (I) of fabric specimens. It revealed that ZnO- and ATO-embedded yarns mixed with ZrC particles enhanced thermal wear comfort and had superior anti-static and UV-protective properties. Considering UV-protective and anti-static protective clothing worn in gas and oil industries and cold weather regions, it can be concluded that ZnO/ZrC-incorporated fabric is suitable because it showed superior thermal wear comfort with excellent UV-protective and acceptable anti-static properties. Meanwhile, assuming high functional performance for protective clothing worn in winter and factories, ZnO/ATO-incorporated fabric is pertinent to fabricating protective clothing for cold weather regions.

Protective clothing in gas and oil industries requires high-performance characteristics, with superior anti-static and ultraviolet (UV) protection and good thermal wear comfort in cold weather regions. This study examined the manufacturing and properties of various ceramic-embedded composite fabrics made from a new scheme (not a coating method) for protective clothing in the gas and oil industries. Therefore, sheath–core yarn specimens embedded with various ceramics, such as aluminum oxide (Al2O3)–graphite, zinc oxide–zirconium (ZnO–ZrC), and zinc oxide–antimony tin oxide (ZnO–ATO) were produced using a bi-component melt spinning machine, which is a novel method that was not tried before. Fabric specimens were also made from these ceramic-embedded sheath–core yarn specimens. UV-protection and anti-static properties of the ceramic-embedded composite specimen were compared with the thermal radiation and far-infrared (FIR) characteristics. The UV-protection factor (UPF) was measured according to the AS/NZ 4399 (1996) standard. ATLAS measuring equipment was used to analyze five duplicate specimens (4 × 8 cm). An anti-static assessment was also conducted using the JIS L 1094 standard method. A light heat emission apparatus was used to assess thermal radiation. A 10 × 10 cm specimen was prepared, and five duplicate assessments were conducted. Statistical analysis (F-test) was performed to verify the statistical significance of the experimental data with a 99% confidence limit. The ZnO–ATO-embedded composite fabric exhibited greater UV protection than the Al2O3–graphite-embedded and regular (control) specimen, indicating the excellent UV-protection property of the ZnO. In addition, the ZnO–ATO-embedded composite specimen exhibited excellent anti-static properties with lower rub-static voltage than the control fabric, which was attributed to the better electrical conductivity of ATO particles. In particular, the ZnO–ZrC-embedded composite specimen showed superior thermal radiation with excellent UPF and relatively good anti-static characteristics. Based on the high-performance characteristics of protective clothing worn in gas and oil industries, ZnO–ATO-embedded composite fabric has practical use for fabricating workwear protective clothing. In addition, considering protective clothing suitable for cold weather, ZnO–ZrC-embedded composite fabric is useful for protective clothing in cold weather regions. Full article

The disintegration of a continuous metallic thin film leads to the formation of isolated islands, which can be used for the preparation of plasmonic structures. The transformation mechanism is driven by a thermally accelerated diffusion that leads to the minimalization of surface free energy in the system. In this paper, we report the results of our study on the disintegration of gold thin film and the formation of nanoislands on silicon substrates, both pure and with native silicon dioxide film. To study the processes leading to the formation of gold nanostructures and to investigate the effect of the oxide layer on silicon diffusion, metallic film with a thickness of 3 nm was deposited by molecular beam epitaxy (MBE) technique on both pure and oxidized silicon substrates. Transformation of the thin film was observed by low-energy electron microscopy (LEEM) and a scanning electron microscope (SEM), while the nanostructures formed were observed by atomic force microscope (AFM) method. Structural investigations were performed by low-energy electron diffraction (LEED) and X-ray photoelectron spectroscopy (XPS) methods. Our experiments confirmed a strong correlation between the formation of nanoislands and the presence of native oxide on silicon substrates. Full article

Recently, an interest in NASICON-type materials revived, as they are considered potential cathode materials in sodium–ion batteries used in large-scale energy storage. We applied a facile technique of thermal nanocrystallization of glassy analogs of these compounds to enhance their electrical parameters. Six nanomaterials of the Na3M2(PO4)2F3 (M = V, Ti, Fe) system were studied. Samples with nominal compositions of Na3V2(PO4)2F3, Na3Ti2(PO4)2F3, Na3Fe2(PO4)2F3, Na3TiV(PO4)2F3, Na3FeV(PO4)2F3 and Na3FeTi(PO4)2F3 have been synthesized as glasses using the melt-quenching method. X-ray diffraction measurements were conducted for as-synthesized samples and after heating at elevated temperatures to investigate the structure. Extensive impedance measurements allowed us to optimize the nanocrystallization process to enhance the electrical conductivity of cathode nanomaterials. Such a procedure resulted in samples with the conductivity at room temperature ranging from 1×10−9 up to 8×10−5 S/cm. We carried out in situ impedance spectroscopy measurements (in an ultra-high-frequency range up to 10 GHz) and compared them with thermal events observed in differential thermal analysis studies.

Low-emissivity glass has high transmission in the visible region and high reflectivity in the infrared region. Gallium and aluminum codoped zinc oxide (GAZO) processed by hydrogen (H2) plasma treatment holds promise for fabricating good low-emissivity glass. The applied processing time is one of the key factors in plasma treatment. The GAZO films were prepared by in-line sputtering at room temperature, and the effect of using different plasma processing times on the structural, electrical and optical properties of the films were surveyed. Experimental results indicate that H2 plasma treatment of GAZO film samples indeed influenced the structure, optical and electrical properties. An appropriate processing time can improve the electrical properties and reduce the emissivity of GAZO films. The optimum processing time is 5 min for plasma treatment of GAZO films. The electrical resistivity and emissivity of plasma-annealed films for 5 min decrease by 59% and 55% compared to those of as-deposited GAZO films. Values of 5.3 × 10−4 Ω-cm in electrical resistivity, 0.13 in emissivity and 94% in average optical transmittance in the visible wavelength region could be obtained for GAZO films after H2 treatment of 5 min in this work for low-emissivity glass applications.

The influence of thin gold electrodes on the electrical measurements of glasses at high temperatures was studied using impedance spectroscopy. The impedance was measured several times over a wide frequency range from 10 mHz to 1 MHz and the temperature ranged from 213 to 673 K under air and nitrogen atmospheres. The results showed a drop in the conductivity of more than an order of magnitude at a temperature around 603 K during heating. An additional relaxation process was found at the low-frequency region. The occurred process was correlated with the thermal disintegration of the gold nano-layer used as an improvement in the electrical contact. The possible ambiguous interpretation of high-temperature impedance spectra was presented as a consequence of performing the electrical measurements only during heating or cooling while using unstable thin gold electrodes. Moreover, a possible solution to this problem was proposed. Full article
