| 1 | Supercritical water oxidation of polyvinyl alcohol and desizing wastewater: Influence of NaOH on the organic decomposition显示文摘Polyvinyl alcohol is a refractory compound widely used in industry. Here we report supercritical water oxidation of polyvinyl alcohol solution and desizing wastewater with and without sodium hydroxide addition. However, it is difficult to implement complete degradation of organics even though polyvinyl alcohol can readily crack under supercritical water treatment. Sodium hydroxide had a significant catalytic effect during the supercritical water oxidation of polyvinyl alcohol. It appears that the OH ion participated in the C-C bond cleavage of polyvinyl alcohol molecules, the CO2-capture reaction and the neutralization of intermediate organic acids, promoting the overall reactions moving in the forward direction. Acetaldehyde was a typical intermediate product during reaction. For supercritical water oxidation of desizing wastewater, a high destruction rate (98.25%) based on total organic carbon was achieved. In addition, cases where initial wastewater was alkaline were favorable for supercritical water oxidation treatment, but salt precipitation and blockage issues arising during the process need to be taken into account seriously. | Jie Zhang Shuzhong Wang Yang Guo Donghai Xu Yanmeng Gong Xingying Tang | 2013 | Journal of Environmental Sciences2013，25，8： | 15 |

| 3 | Speech Enhancement Using Multi-channel Post-Filtering with Modified Signal Presence Probability in Reverberant Environment显示文摘In this paper, a multi-channel post-filtering approach in reverberant environment based on detection and estimation scheme is presented. A modified Signal presence probability(SPP), which is in consideration of reverberation, is proposed with a novel estimator Direct-toreverberate ratio(DRR) to adapt to distant-talking scene.SPP is known a key estimator to instruct the updating of transient noise or residual directional interference and form gain function in the time-frequency domain, consequently a new desired signal detection scheme is proposed to improve its accuracy. Appropriate spectral enhancement technique is applied to the noisy speech signal taking advantage of the modified SPP estimator. The proposed multi-channel post-filtering is tested in different nonstationary noisy and reverberant environments. Experimental results show that it achieves considerable improvement on signal preservation of the desired speech with more noise reduction over the comparative algorithms. | WANG Xiaofei GUO Yanmeng FU Qiang YAN Yonghong | 2016 | Chinese Journal of Electronics2016，25，3： | 3 |

| 7 | A Robust Step-Size Control Technique Based on Proportionate Constraints on Filter Update for Acoustic Echo Cancellation显示文摘One of the main difficulties in Acoustic echo cancellation(AEC) is that the filter adaptation needs to vary according to different situations such as near-end interferences and echo path changes.In this paper,we propose a robust step-size control algorithm in frequency domain.The proposed method is based on the optimization of the square of the bin-wise a posteriori error.Constraint on the filter update is applied,which contributes to robustness to near-end interferences of the algorithm.The learning rate formula is derived first and then the relationship between the proposed algorithm and a robust statistics based approach is revealed.The method is extended to the Multidelay block frequency domain adaptive filter(MDF) so as to meet the demand of low delay in practical application.Moreover,the values of the constraints are designed to be updated proportionately to improve the convergence property.Simulation results demonstrate the superiority of the proposed algorithm. | WU Chao JIANG Kaiyu WANG Xiaofei GUO Yanmeng FU Qiang YAN Yonghong | 2016 | Chinese Journal of Electronics2016，25，4： | 0 |
| 8 | 基因组和转录组测序整合分析揭示混合型肝癌的不同分子亚型显示文摘文章简介原发性肝癌每年造成全球约70万病人死亡且过半死亡病例来自中国,其致死率在所有癌种中高居第二。肝癌主要分为3种类型:肝细胞癌(约80%)、肝内胆管癌(约15%)和混合型肝癌(约5%)。混合型肝癌兼具肝细胞癌和胆管细胞癌两种成分,是预后最差的一种肝癌。 | 薛瑞栋 陈璐 张冲 藤田征志 Ruoyan Li Shu-Mei Yan Choon Kiat Ong Xiwen Liao Qiang Gao Shota Sasagawa Yanmeng Li Jincheng Wang Hua Guo Qi-Tao Huang Qian Zhong Jing Tan Lisha Qi Wenchen Gong Zhixian Hong Meng Li Jingmin Zhao Tao Peng Yinying Lu Kiat Hon Tony Lim Arnoud Boot Atushi Ono Kazuaki Chayama Zemin Zhang Steve George Rozen Bin Tean Teh Xin Wei Wang Hidewaki Nakagawa 曾木圣 白凡 张宁 | 2020 | 科学新闻2020，，2： | 0 |
| 9 | Enhanced photocatalytic hydrogen production under visible light of an organic-inorganic hybrid material based on enzo[1,2-b:4,5-b']dithiophene polymer and TiO_(2)显示文摘Titanium dioxide(TiO_(2))has been limited in photocatalysis due to its wide band gap(3.2 eV)and limited absorption in the ultraviolet range.Therefore,organic components have been introduced to hybrid with TiO_(2) for enhanced photocatalytic efficiency under visible light.Here,we report that benzo[1,2-b:4,5-b']dithiophene polymer was an ideal organic material for the preparation of a hybrid material with TiO_(2).The energy band gap of the resulting hybrid material decreased to 2.9 eV and the photocatalytic hydrogen production performance reached 745.0μmol g^(-1) h^(-1) under visible light irradiation.Meanwhile,the material still maintained the stability of hydrogen production performance after 40 h of photocatalytic cycles.The analysis of the transient current response and electrochemical impedance revealed that the main reasons for the enhanced water splitting of the hybrid materials were the faster separation of electron hole pairs and the lower recombination of photocarrier ions.Our findings suggest that polythiophene is a promising organic material for exploring hybrid materials with enhanced photocatalytic hydrogen production. | Fang Jing Yanmeng Guo Bo Li Yi-Fan Chen Chunman Jia Jianwei Li | 2022 | Chinese Chemical Letters2022，33，3： | 0 |
