Synthesis of Zirconia Oxide (ZrO<sub>2</sub>) Nanofibers on Zirconnia Substrates by Ultrasonic Spray Pyrolysis

引用

Materials Sciences and Applications 2014年第4期5卷 193-198页

作者： jianhui zhang Wei Li Takayoshi Tanji EcoTopia Science Institute Nagoya University Nagoya Japan Global Research Center for Environment and Energy Based on Nanomaterials Science Nagoya Japan Graduate School of Engineering Nagoya Japan

Zirconia oxide (ZrO2) nanofibers were synthesized using Phosphorus/water mixture as catalyst by ultrasonic spray pyrolysis CVD on the zirconia substrate at 900°C for 1 h in N2 gas. Scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) examinations show that all the synthesized nanofibers have uniform surface morphology and their diameters are in the range of 100 nm. The HRTEM selected-area electron diffraction pattern (SAED) shows that crystalline ZrO2 phase exist in the nanofibers, and the energy-dispersive x-ray spectroscopy (EDS) results show that the elements of Zr and O are uniformly distributed across the nanofiber matrix. The phosphorus atoms corroded the entire Zirconia substrate surface, and the Zirconia-Phosphorus liquid-catalyzed the solid-liquid-solid mechanism is proposed to explain the growth of the nanofibers.

An Efficient and Fast Area Optimization Approach for Mixed Polarity Reed-Muller Logic Circuits

引用

Chinese Journal of Electronics 2024年第5期33卷 1165-1180页

作者： Yuhao ZHOU Zhenxue HE jianhui JIANG Xiaojun ZHAO Fan zhang Limin XIAO Xiang WANG School of Software Engineering Tongji University Key Laboratory of Agricultural Big Data of Hebei Province Hebei Agricultural University School of Computer Science and Engineering Beihang University School of Electronic and Information Engineering Beihang University

Area has become one of the main bottlenecks restricting the development of integrated circuits. The area optimization approaches of existing XNOR/OR-based mixed polarity Reed-Muller(MPRM) circuits have poor optimization effect and efficiency. Given that the area optimization of MPRM logic circuits is a combinatorial optimization problem, we propose a whole annealing adaptive bacterial foraging algorithm(WAA-BFA), which includes individual evolution based on Markov chain and Metropolis acceptance criteria, and individual mutation based on adaptive probability. To address the issue of low conversion efficiency in existing polarity conversion approaches, we introduce a fast polarity conversion algorithm(FPCA). Moreover, we present an MPRM circuits area optimization approach that uses the FPCA and WAA-BFA to search for the best polarity corresponding to the minimum circuits area. Experimental results demonstrate that the proposed MPRM circuits area optimization approach is effective and can be used as a promising EDA tool.
