Electron transport behaviour in InSb semiconductor significantly changes when the conduction is restricted to two-dimensions. Semiconductor materials are an effective tools to characterize the electron transport in this aspect because the energy separation between transverse modes in a low-dimensional semiconductor device are always inversely proportional to the effective mass, in the same way as for sub-bands in a parabolic potential. Therefore, in this article, a range of novel device geometries were designed, fabricated and characterized to investigate ballistic transport of electrons in low-dimensional InSb structures using surface gated devices to restrict the degrees of freedom (dimensionality) of the active conducting channel. In this framework, designs of gates (i.e., line, loop and solid discussed later) have been used over a range of gate dimensions. Consistent measurement of quantised conductance would be promising for both low power electronics and low temperature transport physics where split gates are typically used for charge sensing. This article presents an experimental results of quantization conductance obtained for the range geometries of novel gates, and some model consideration of the implications of the material choice. Furthermore, the etching techniques (wet and dry) exhibited a significant decrease of ohmic contact resistance from around 35kΩ to only roughly 250Ω at room temperature. Interestingly a possible 0.7 anomaly conduction was observed with a loop gate structure. This work showed perfectly that the two-dimensional electron gases can be formed in narrow gap InSb QWs which makes this configuration device promising candidate for topological quantum computing and next generation integrated circuit applications. Keywords: Quantization conductance, InSb QW, 2DEG, spilt gate structure, ballistic transport.
当传导限制在二维范围内时,InSb 半导体中的电子传输行为会发生显著变化。半导体材料是表征这方面电子传输特性的有效工具,因为低维半导体器件中横向模式之间的能量分离总是与有效质量成反比,这与抛物线势中子带的情况相同。因此,本文设计、制造并表征了一系列新型器件几何结构,利用表面门控器件限制有源导电通道的自由度(维度),研究电子在低维 InSb 结构中的弹道传输。在这一框架中,栅极的设计(即线型、环型和稍后讨论的实体型)被用于一系列栅极尺寸。量化电导的一致性测量对于低功耗电子学和低温传输物理学都很有前景,因为在低温传输物理学中,分裂栅极通常用于电荷传感。本文介绍了新型栅极几何尺寸范围内量化电导的实验结果,以及对材料选择影响的一些模型考量。此外,在室温下,蚀刻技术(湿法和干法)显示欧姆接触电阻从大约 35kΩ 显著下降到大约 250Ω。有趣的是,在环形栅极结构中可能出现了 0.7 的反常传导。这项工作完美地表明,二维电子气可以在窄间隙 InSb QW 中形成,这使得这种配置器件成为拓扑量子计算和下一代集成电路应用的理想候选器件。关键词量子化电导、InSb QW、二维电子气体、栅极结构、弹道传输。

As a preliminary step to establish technology for fabricating High-Entropy Alloys (HEAs) that can make a large-scale HEA using a pulse laser with high peak intensity and high-repetition in the future, we fabricated alloys in which two types of metal atom are mixed close together in the order of nanometers. For the method to produce the alloy, metal alloy nanoparticles were prepared by irradiating the material in liquid with focused high-repetition Q-switched laser pulses using an in-liquid laser ablation method. When brass powder was used as an original material, analysis results by TEM showed that numerous nanoparticles mixed with copper and zinc atoms could be produced. Furthermore, it was clarified by SEM EDS that copper and zinc atoms in the nanoalloy were maintained at a ratio of 3:1 in sintered alloy, and that the atoms were spatially uniformly distributed over a wide range in sintered metal.

This work investigates the properties of copper thin films deposited by magnetron sputtering. The substrate is biased by a negative voltage (Vs), which controls the energy ions bombardment during the deposition of the thin films. In order to focus solely on the ions energy contribution, the power supply was fixed and the working pressure was selected at 5 Pa. This ensures energetic sputtered particles completely thermalized, by a sufficient number of collisions with the Argon gas. X-ray diffraction analysis revealed that substrate voltage Vs affects essentially the structure and size of the formed crystallites. The preferred orientation (111) and the larger crystallite size (30 nm) were achieved at Vs = - 60 V. The Cu (111)/(200) peak intensity ratio is maximal (12.55) at - 60 V, corresponding to the lowest resistivity value (6.33 mW.cm). Optimum corrosion resistance of the deposited thin film was achieved at -60 V. At high crystallite sizes, nanoindentation analysis showed a thin film that is more elastic (133 GPa) and less hard (1.96 GPa).
这项研究探讨了磁控溅射沉积铜薄膜的特性。基片由负压(Vs)偏置,负压控制着薄膜沉积过程中的离子轰击能量。为了只关注离子的能量贡献,电源是固定的,工作压力选为 5 Pa。这确保了高能溅射粒子通过与氩气的充分碰撞而完全热化。X 射线衍射分析表明,基底电压 Vs 主要影响所形成晶体的结构和尺寸。当电压 Vs = - 60 V 时,可获得较好的取向(111)和较大的晶体尺寸(30 nm)。在 - 60 V 时,铜 (111)/(200) 峰强度比最大(12.55),对应的电阻率值最低(6.33 mW.cm)。沉积薄膜在 -60 V 时达到最佳耐腐蚀性。在高晶粒尺寸下,纳米压痕分析表明薄膜的弹性更大(133 GPa),硬度更低(1.96 GPa)。

The dust accumulation and dirt particles always degrade the transparency of glass, later hampers its various applications such as photovoltaic panels, building glass, and car-windshield. In this study, the hydrophilic self-cleaning coatings have been developed by using the nanocalcium Carbonate particles (nanoCaCO3) and hydrophilic micro-titanium dioxide particles (µ-TiO2). The presence of oxide groups, CO-3 and TiO2- forms a strong attraction of glass to polar water molecules. At the weight ratio of 1: 1 in the CaCO3 to TiO2 mixture, it forms a great hydrophilic property in which the water contact angle (WCA) of coated glass has been recorded as low as 11.46 ±0.85°. The coated glass also showed high transparency in UV and Visible regions. The optical transmission of coated glass was above 89% at the wavelength of 300-400nm and above 97% at the wavelength of 400-800nm. Due to its hydrophilic property, the coated glass is capable of removing the dust particles away via the water stream. The hydrophilic coating spontaneously forms the water-thin film after contact with coated glass without the presence of UV light.
灰尘堆积和污垢颗粒总是会降低玻璃的透明度,进而阻碍其在光伏板、建筑玻璃和汽车挡风玻璃等领域的广泛应用。本研究利用纳米碳酸钙颗粒(nanoCaCO3)和亲水性微二氧化钛颗粒(µ-TiO2)开发了亲水性自清洁涂层。氧化物基团(CO-3 和 TiO2-)的存在使玻璃对极性水分子产生强大的吸引力。当 CaCO3 与 TiO2 混合物的重量比为 1:1 时,就会形成很强的亲水性,镀膜玻璃的水接触角 (WCA) 低至 11.46 ±0.85°。镀膜玻璃在紫外线和可见光区域也表现出很高的透明度。镀膜玻璃在波长 300-400nm 处的光学透射率超过 89%,在波长 400-800nm 处的光学透射率超过 97%。由于具有亲水性,镀膜玻璃能够通过水流带走灰尘颗粒。在没有紫外线的情况下,亲水涂层在与镀膜玻璃接触后会自发形成水薄膜。

The removal of dyes and pathogens from contaminated water remains a significant challenge. In the present study, NaNbO3 and NaNbO3/Bi2S3 powders were prepared by a simple hydrothermal method, and then the noble metal Ag was successfully deposited on NaNbO3/Bi2S3 by photoreduction to constitute the NaNbO3/Bi2S3/Ag ternary nanorods heterostructure. With continuous visible light irradiation and controlled temperature variation (25-55 °C), the monomeric NaNbO3 could degrade 73.3% of Rhodamine B (RhB) and inactivated 46% of Salmonella while the ternary complex NaNbO3/Bi2S3/Ag showed a higher RhB degradation efficiency of 94.9% as well as an higher sterilization efficiency of 82%. In addition, after four replicate experiments, NaNbO3/Bi2S3/Ag still had a high degradation efficiency. Compared with NaNbO3 monomer, NaNbO3/Bi2S3/Ag possessed stronger catalytic ability. The improvement of catalytic activity could be attributed to the efficient separation of pyroelectric and photocatalytic electrons and holes through the formation of NaNbO3/Bi2S3/Ag heterostructural nanorod.

This study employed an innovative approach, utilizing prepared dried polyurethane-polyaniline nano-composite, through in-situ polymerization, for continuous remediation of Congo red dye. Response Surface Methodology (RSM) based on the Box-Behnken design (BBD) model was utilized to optimize the processing parameters, including initial dye concentration, flow rate, and pH. The two-factor interaction (2FI) model emerged as the most significant, highlighting the influence of individual and interaction effects of the factors. Optimization of the dye remediation process yielded the optimal conditions of a flow rate of 10 mL/min, acidic pH of 5.00, and dye concentration of 20 mg/L, resulting in an impressive, predicted removal efficiency of 99.09% agreeing with the experimental value. Moreover, the maximum adsorption capacity was determined to be 329.68 mg/g. Characterization of the adsorbent material involved techniques such as Scanning electron microscopy (SEM), Fourier transforms infrared spectra (FTIR), X-ray spectroscopy (XRD), and Zeta potential analysis. This material offers a sustainable alternative in industries to treat Congo red dye before being disposed of into the environment.

Recoverable and stable nanocatalysts are essential for peroxymonosulfate - based advanced oxidation processes (AOPs) in wastewater purification treatment. In this paper, Fe3C nanorods @ nitrogen-doped carbon composites (N-Fe3C@C) with core-shell architecture were fabricated by the co-precipitation and calcination methods, and characterized and analyzed in terms of their crystal structure, microscopic morphology, and surface chemical elements. In addition, N-Fe3C@C-4 degraded 85.36% of tetracycline in 10 min under PMS, which was much higher than the catalytic ability of Fe3O4 (42.03% in 10 min). Both the active radical trapping and EPR experiments verified that 1O2 played a key role for degradation of organic dyes in PMS system.

在废水净化处理中,可回收且稳定的纳米催化剂对于基于过一硫酸盐的高级氧化工艺(AOPs)至关重要。本文通过共沉淀和煅烧方法制备了具有核壳结构的 Fe3C 纳米棒 @ 掺氮碳复合材料(N-Fe3C@C),并对其晶体结构、微观形貌和表面化学元素进行了表征和分析。结果表明,N-Fe3C@C-4在PMS条件下10分钟内降解85.36%的四环素,远高于Fe3O4的催化能力(10分钟内降解42.03%)。活性自由基捕获和 EPR 实验都验证了 1O2 在 PMS 体系中对有机染料的降解起着关键作用。对降解机理的研究表明,碳层的存在有利于吸附 TC,加速自由基的生成,促进纳米催化剂中 Fe2+/Fe3+ 的氧化还原循环。这项研究为先进的废水净化处理多功能催化剂提供了新的思路。

The study aims to evaluate the effect of silver and gold nanoparticles during the laser cleaning process of glass artifacts. It is the first time that nanoparticles have been used to clean antique glass, as far as the authors are aware. In the context of this study, work was done on glass samples extracted from excavations that suffer from dense layers of corrosion products, soil deposits, brittle, easy to break, and cannot bear pressure. To characterize the investigated glass shards and assess the cleaning procedure, a variety of analytical techniques, including the transmission electron microscope (TEM), digital microscope, stereomicroscope, scanning electron microscope (SEM-EDX), X-ray diffraction (XRD), and color change measurement, have been used. The XRD analysis revealed different minerals such as ferrosilite, hillebrandite, and jacobsite, in the black corrosion layer, and calcite, syngenite, and arcanite in the white crust layer. The results of the microscopic examination employed in the evaluation procedure demonstrated that using Ag NPs with laser perfectly removed the tough crust layers without scratching the surface. The cleaned surface became smooth, homogenous and more transparent. The elemental analysis results by (SEM-EDX) revealed a significant reduction in the proportion elements of the (Al, Fe, p, and Mg) in the corrosion layer and their loss in the cleaned areas. Measurement of color change indicated that laser-treated glass samples with the addition of Ag NPs gave higher (ΔE*), confirming the influential role of this method in cleaning archaeological glass. It was also observed that the effect of Ag NPs with Laser assistance decreases the required time for the cleaning process. Thus the heat generated by the laser-treated was reduced, so the laser-treated with Ag NPs is recommended for use in the archaeological glass cleaning process.
该研究旨在评估激光清洁玻璃文物过程中纳米银和纳米金粒子的效果。据作者所知,这是首次使用纳米粒子来清洁古董玻璃。在这项研究中,我们对从出土文物中提取的玻璃样品进行了研究,这些玻璃样品上有密集的腐蚀产物层和土壤沉积物,质地脆、易碎且无法承受压力。为了确定所调查玻璃碎片的特征并评估清洁程序,使用了多种分析技术,包括透射电子显微镜(TEM)、数码显微镜、体视显微镜、扫描电子显微镜(SEM-EDX)、X 射线衍射(XRD)和颜色变化测量。X 射线衍射分析表明,黑色腐蚀层中有铁硅石、黑云母和黝帘石等不同矿物,白色结壳层中有方解石、黝帘石和芒硝等不同矿物。评估程序中使用的显微镜检查结果表明,使用银氧化物和激光可以完美地去除坚硬的结壳层,而不会划伤表面。清洁后的表面变得光滑、均匀且更加透明。通过 SEM-EDX 进行的元素分析结果表明,腐蚀层中的(铝、铁、钯和镁)元素比例显著降低,并且在清洁区域中的比例也有所降低。颜色变化的测量结果表明,添加了 Ag NPs 的激光处理玻璃样品具有更高的 (ΔE*) 值,这证实了该方法在清洁考古玻璃方面的重要作用。此外还观察到,在激光的辅助下,Ag NPs 的作用缩短了清洁过程所需的时间。因此,建议在考古玻璃清洗过程中使用经过激光处理的 Ag NPs。

Photocatalytic technology is one of the promising technologies for wastewater treatment. Herein, zinc oxide/multi-walled carbon nanotubes (ZnO/CNTs) photocatalyst was successfully prepared by hydrothermal method with combining in-situ synthesis technology. The micro-morphology, crystalline structure, surface chemical elements, and optical properties were characterized by SEM, TEM, XRD, FTIR, UV-Vis, and DRS technologies. The ZnO/CNTs photo-catalyst exhibited enhancement photo activity for degradation of organic pollutants under simulated light irradiation. Specifically, the photo-catalytic activity of the ZnO/CNTs catalysts improved with the rise of CNTs content in the composites. Investigation on the photo-degradation mechanism verified that the presence of CNTs in the catalyst not only optimized the band structure of ZnO semiconductor but also contributed to the transfer of photo-generated electrons and reducing the recombination of electron-hole pairs due to its excellent conductivity. Moreover, the active radical groups such as superoxide radical (O-2), hole (h+), and hydroxyl radical (·OH) played the dominated role for the pollutants degradation under the simulated sunlight irradiation. In addition, ZCT20 catalysts and light irradiation had synergistic effects on antibacterial activity, whose antibacterial rates against E. coli and S. aureus were up to 99.96% and 99.94%, respectively. Investigation on antibacterial mechanisms revealed that the existence of ROS and the continuous release of Zn2+ played an important role for improving the antibacterial activity of the ZCT20 catalyst under the simulated sunlight irradiation.
光催化技术是一种前景广阔的废水处理技术。本文结合原位合成技术,采用水热法成功制备了氧化锌/多壁碳纳米管(ZnO/CNTs)光催化剂。通过 SEM、TEM、XRD、FTIR、UV-Vis 和 DRS 技术对其微观形貌、晶体结构、表面化学元素和光学性能进行了表征。在模拟光照射下,ZnO/CNTs 光催化剂具有增强降解有机污染物的光活性。具体而言,ZnO/CNTs 催化剂的光催化活性随着复合材料中 CNTs 含量的增加而提高。对光降解机理的研究证实,催化剂中 CNT 的存在不仅优化了 ZnO 半导体的能带结构,而且由于 CNT 具有良好的导电性,有助于光生电子的转移和减少电子-空穴对的重组。此外,在模拟太阳光照射下,超氧自由基(O-2)、空穴(h+)和羟基自由基(-OH)等活性自由基在污染物降解过程中发挥了主导作用。此外,ZCT20 催化剂和光照对抗菌活性具有协同作用,其对大肠杆菌和金黄色葡萄球菌的抗菌率分别高达 99.96% 和 99.94%。抗菌机理研究表明,在模拟阳光照射下,ROS 的存在和 Zn2+ 的持续释放对提高 ZCT20 催化剂的抗菌活性起了重要作用。
