Image-to-image Translation for Enlargement of Aircraft Skin Defect Datasets

2022 IEEE 4th International Conference on Civil Aviation Safety and Information Technology (ICCASIT) (2023)

Abdul Nasser Kasule Meng Ding Yiming Xu Juan Xu

With the size and diversity of a dataset being integral to the accuracy of aircraft skin defect detection models, it can be argued that the currently available small aircraft skin defect datasets need to be greatly increased. In this paper, we suggest employing image-to-image translation techniques, specifically the CycleGAN network combined with perceptual loss. By exploiting the CycleGAN network's ability to generate images similar to those fed into the network, we aim to increase the size of an available aircraft skin damage dataset through the generation of synthetic images. The addition of perceptual loss further enhances the quality and realism of generated images. Through image evaluation with Fréchet Inception Score, we showcase how this method has the capacity to address the challenge posed by limited datasets for small aircraft skin damage.

Carbon Nanoparticles as Chromophores for Photon Harvesting and Photoconversion

ChemPhysChem (2011)

Juan Xu Sushant Sahu Li Cao Parambath Anilkumar Kenneth N. Tackett

Abstract Carbon nanomaterials have generated a tremendous amount of attention in the scientific community. While most of the research and development efforts have been on fullerenes, carbon nanotubes, and graphene sheets, carbon nanoparticles (which are often considered as impurities or unwanted complications in the other carbon nanomaterials) have recently emerged as a unique class of highly fluorescent nano‐dots. However, little or no attention has been paid to potential uses of carbon nanoparticles as chromophores in photochemical reactions or for photon harvesting and photoconversion in general. In the study reported herein we demonstrate the chromophore‐equivalent functions of aqueous‐suspended small carbon nanoparticles in harvesting visible photons for the reductive coating of the nanoparticles with silver and gold and, as a result, the preparation of unique carbon–noble‐metal core–shell nanostructures.

Electrochemical properties of novel titania nanostructures

Nanotechnology (2015)

Sunqi Lou Fei Teng Juan Xu Zailun Liu Yongfa Zhu

In this study, the supercapacitive properties of six new TiO2 nanostructures—including nanodishes, three-layer nanosheets, ancient Chinese coins, single-layer nanosheets, hollow nanocubes, and commercial rutile TiO2 are investigated mainly by cyclic voltammetry, chronopotentiometry, and electrochemical impedance spectroscopy. The results show that among them, the TiO2 nanodishes have the highest discharging capacitance at 1792 mFg−1, which is 6.4 and 1.5 times higher than that of TiO2 single-layer nanosheets and commercial rutile TiO2, respectively. We found that the electrochemical properties of the TiO2 samples are predominated primarily by the high-energy facets exposed, instead of by the Brunauer–Emmett–Teller area. An important and previously unknown finding of our work is that the electrochemical properties of electrode materials can be improved by controlling the high-energy facets.

Hydrogen Bond Cross-Linked Montmorillonite-Enhanced Biodegradable Carboxymethyl Cellulose/Guar Gum Composite Films

ACS Applied Polymer Materials (2024)

Xin Shi Mengmeng Kang Huihui Zhang Juan Xu Chenkai Wang

Carboxymethyl cellulose (CMC) has attracted considerable interest in research due to its exceptional film-forming properties and compatibility with biological systems. However, CMC films still suffer from mechanical brittleness and structural instability due to the rigid structure and many hydroxyl groups in practical applications. Herein, a nanocomposite film is reported, synthesized via inserting layered montmorillonite (MMT) into a CMC and guar gum (GG) hydrogen bond networks. Incorporating MMT with a high aspect ratio increases the number of hydrogen bond cross-linking sites among constituents, thereby enhancing the mechanical strength and toughness of nanocomposite films. The resulting CMC/GG10/MMT6 films show flexibility (elongation at break 83.5 ± 4.35%), high tensile strength (53.5 ± 1.10 MPa), and high toughness (32.16 ± 1.04 MJ/m3). These films also integrate hydrophobic (up to 84.78°) and high-temperature resistance (50% degradation temperature up to 304 °C) properties to adapt to complex practical application environments. Moreover, they exhibit excellent ultraviolet shielding performance under a wide wavelength range (200–320 nm). Soil burial experiments showed that all the films could be assimilated into the soil within about 9 days. This approach offers a simple and promising route for producing biodegradable CMC-based films for food packaging.
