  2. Article: Evolution of the oxidation behaviors of highly oxidation-resistant (Ti₀.₈Nb₀.₂)C in 1000–1200 °C steam

    Abstract The evolution of the oxidation behaviors of the highly oxidation-resistant (Ti₀.₈Nb₀.₂)C was investigated in a 1000–1200 °C steam environment. For the specimen oxidized below 1200 °C, a compact oxide layer less than 7 μm thick was obtained. By increasing the temperature to 1200 °C, the oxide layer grows quickly to over 30 μm. Variable distribution of Ti and Nb in the oxide scales reveals the significance of the outward diffusion of the metal elements during oxidation. Synchronized variations in Ti and Nb were observed in the specimen oxidized below 1200 °C, while the distribution trends of Ti and Nb were opposite in the specimen oxidized at 1200 °C. The incorporation of Nb effectively lowered the diffusion rate of Ti through the oxide scales and the grain growth of the oxides. Suppressed diffusion and dense oxide scales are responsible for the excellent oxidation resistance of (Ti₀.₈Nb₀.₂)C below 1200 °C.

    Abstract A novel class of high-entropy pyrochlore ceramics (HEPCs) with multiple heavy and light rare-earth elements at the A site were successfully synthesized via solid-state reaction. Both the XRD patterns and Raman spectroscopy demonstrated the single pyrochlore structure feature of seven kinds of HEPCs. Electron microscopic images revealed the typical morphology and the homogeneous distribution of all rare-earth elements. It can be concluded that the significance of configuration entropy in the HEPC system has promoted the tervalent lanthanide nuclides to form a single pyrochlore structure. This work is expected to provide guidance for the further design of high-entropy pyrochlore/fluorite ceramics.

    Abstract CNN-based salient object detection (SOD) methods achieve impressive performance. However, the way semantic information is encoded in them and whether they are category-agnostic is less explored. One major obstacle in studying these questions is the fact that SOD models are built on top of the ImageNet pre-trained backbones which may cause information leakage and feature redundancy. To remedy this, here we first propose an extremely light-weight holistic model tied to the SOD task that can be freed from classification backbones and trained from scratch, and then employ it to study the semantics of SOD models. With the holistic network and representation redundancy reduction by a novel dynamic weight decay scheme, our model has only 100K parameters,  ∼  0.2% of parameters of large models, and performs on par with SOTA on popular SOD benchmarks. Using CSNet, we find that a) SOD and classification methods use different mechanisms, b) SOD models are category insensitive, c) ImageNet pre-training is not necessary for SOD training, and d) SOD models require far fewer parameters than the classification models. The source code is publicly available at https://mmcheng.net/sod100k/.

    Abstract Background: The urban ambient air quality has been largely improved in the past decade. It is unknown whether childhood asthma prevalence is still increasing in ever top-ranking city of Shanghai, whether the improved air quality is beneficial for children's asthma and what time window of exposure plays critical roles.
    Methods: Using a repeat cross-sectional design, we analyzed the association between early life exposure to particles and wheezing/asthma in each individual and combined surveys in 2011 and 2019, respectively, in 11,825 preschool children in Shanghai.
    Results: A significantly lower prevalence of doctor-diagnosed asthma (DDA) (6.6% vs. 10.5%, p < 0.001) and wheezing (10.5% vs. 23.2%, p < 0.001) was observed in 2019 compared to 2011. Exposure to fine particulate matter (PM
    Conclusions: Improved ambient PM benefits in decreasing childhood asthma prevalence. We firstly reported the finding of SEW to PM at or closely after weaning on childhood asthma.

    Abstract Salient object detection models often demand a considerable amount of computation cost to make precise prediction for each pixel, making them hardly applicable on low-power devices. In this paper, we aim to relieve the contradiction between computation cost and model performance by improving the network efficiency to a higher degree. We propose a flexible convolutional module, namely generalized OctConv (gOctConv), to efficiently utilize both in-stage and cross-stages multi-scale features, while reducing the representation redundancy by a novel dynamic weight decay scheme. The effective dynamic weight decay scheme stably boosts the sparsity of parameters during training, supports learnable number of channels for each scale in gOctConv, allowing 80% of parameters reduce with negligible performance drop. Utilizing gOctConv, we build an extremely light-weighted model, namely CSNet, which achieves comparable performance with about 0.2% parameters (100k) of large models on popular salient object detection benchmarks.

    Abstract Plasma electrolytic oxidation (PEO) coatings are fabricated on Zr-4 alloy by a pulsed bipolar power supply. When the anodic voltage remains constant, the variation of cathodic voltage exhibits a significant impact on the microstructure and corrosion resistance of the oxide coatings. Here we systematically investigate the influence of cathodic voltage on the phase composition, morphology, thickness, and elemental composition of the PEO coatings. Corrosion behaviors are evaluated by electrochemical impedance spectroscopy (EIS). The coating thickness and the electrolyte borne elements incorporated in the coatings both increase with the increase of cathodic voltage. It is interesting to note that the relative content of tetragonal ZrO2 and monoclinic ZrO2 also shows a strong cathodic voltage dependence. The coating formed at 50 V cathodic voltage shows the most compact microstructure with the largest amount of tetragonal ZrO2 and correspondingly exhibits the optimized corrosion resistance. The presence of t-ZrO2 is found to be beneficial for dense oxide coatings and better corrosion resistance. Therefore, cathodic voltage is an important parameter during PEO process to adjust the microstructure and the corrosion resistance performance of PEO coatings.
