Solid-liquid-gas reactions are ubiquitous. An understanding of how gases influence the reactions at the nanoscale is significant for achieving the enhanced triple-phase reactions. Here, we report a real-time observation of the accelerated etching of gold nanorods with oxygen nanobubbles in aqueous hydrobromic acid using liquid cell transmission electron microscopy (TEM). Our observation reveals that when an oxygen nanobubble is close to a nanorod below the critical distance (~1nm), the local etching rate is significantly enhanced with over an order of magnitude faster. Molecular dynamics simulations results show that the strong attractive van der Waals interaction between the gold nanorod and oxygen molecules facilitates the transport of oxygen through the thin liquid layer to the gold surface and thus plays a crucial role in increasing the etching rate. This result sheds light on the rational design of solid-liquid-gas reactions for enhanced activities. © 2020, CC BY.

A bacteria-immunity system model is formulated to describe the interaction between bacteria and immune cells with quorum sensing. Time delay is introduced to study this system. The stability and the conditions for the existence of Hopf bifurcation are obtained. Finally, numerical simulations are used to verify the theoretical conclusions. © ISCIIA and ITCA 2018 - 8th International Symposium on Computational Intelligence and Industrial applications and 12th China-Japan International Workshop on Information Technology and Control application.

Multi-view video plus depth (MVD) is an efficient format of 3D video. MVD video can be encoded by either H.264/AVC or HEVC standard to gain higher compression ratio, which benefits their broadcasting over the Internet. However, the encoded and transferred MVD video tends to develop worse visual quality degradation caused by lossy network channel. Therefore, error concealment is here to help refrain this problem. In this paper, we propose a classification-related error concealment method for MVD video. Within our method, motion-based classification is used to judge whether the corrupted blocks are static or not. If so, the blocks from reference frames are adopted to conceal the corrupted blocks. Otherwise, view-specific based concealment procedures, which are designed in accordance with view features, are used to conceal the corrupted blocks in different views. Experimental results on AVC-based Test Model (ATM) show the superiority of this concealment scheme to several other error concealment methods in PSNR along with acceptable execution time increase. © Springer Nature Singapore Pte Ltd. 2017.

Bifurcation and stability analysis for a fractional-order gene regulatory networks with time delay is researched. Firstly, taking time delay as the bifurcation parameter, the Hopf bifurcation and stability conditions are established. Finally, a numerical example verifies the theoretical conclusion. It is showed that time delay can heavily effect the dynamics of the system and each order has a major influence on the creation of bifurcation simultaneously. © ISCIIA and ITCA 2018 - 8th International Symposium on Computational Intelligence and Industrial applications and 12th China-Japan International Workshop on Information Technology and Control application.

SID Symposium Digest of Technical Papers 2019年第S1期50卷

作者： Aiying Guo Feng Ran Jianhua Zhang Microelectronic Research and Development Center Shanghai China Key Laboratory of Advanced Display and System Applications Ministry of Education Shanghai China

In this paper, we propose a new pixel structure for the organic Light Emitting Diode (OLED) 0.65 inch SVGA resolution micro-display with 8 bit gray level. The proposed pixel structure is composed of 4 MOSFETS and one capacitor to integrate the pixel structure in the restricted pixel area (9um×9um) using 0.18um technology. The simulation result shows that the maximum error of emission current occurs at high gray level.
