In this paper, we report a technique for the surface modification of poly-(p-phenylene terephthamide)(PPTA) powder coated with polydopamine(PDOPA). We used air oxidation to self-polymerize dopamine(DOPA) to ensure that the PPTA powder was coated. Our results indicate that the modified surface of PPTA powder enhances compatibility with the polymer matrix without damaging its structure. Additionally, it is possible to control the coating thickness of PDOPA by regulating the reaction time. The modified PPTA powder improved the comprehensive property of ethylene-propylene-diene-terpolymer grafted maleic anhydride(EPDM-g-MAH), and it proved that this method can enhance the strength and electric insulativity of EPDM-g-MAH.

A Low-Power CMOS Analog Front-End IC with Adjustable On-Chip Filters for Biosensors

中国化学会2019能源材料和缺陷化学研讨会

作者： Lushan Ma weibo hu Liangliang Zou Zhiqing Zou Ke Wen hui Yang Shanghai Advanced Research Institute Chinese Academy of Sciences University of Chinese Academy of Sciences

Electrochemical CO reduction(eCOR) via the utilization of renewable and intermittent electricity has emerged as an intriguing approach to reduce anthropogenic CO emission and implement the energy conversion and storage. However, it remains a great challenge to rationally design highly efficient electrocatalysts with well-defined catalytic sites toward high value-added commodities, such as hydrocarbon. Herein, we firstly report stable Cu sites confined in a newly designed covalent triazine framework(CTF) for electrochemical CO reduction to hydrocarbons,

Open Journal of Applied Biosensor 2013年第4期2卷 104-111页

作者： Donald Y. C. Lie Vighnesh Das weibo hu Yenting Liu Tam Nguyen Department of Electrical and Computer Engineering Texas Tech University Lubbock USA Department of Surgery Texas Tech University Health Sciences Center Texas Tech University Lubbock USA

This paper presents a low-power CMOS analog front-end (AFE) IC designed with a selectable on-chip dual AC/DC- coupled paths for bio-sensor applications. The DC-coupled path can be selected to sense a biosignal with useful DC information, and the AC-coupled path can be selected for sensing the AC content of the biosignal by attenuating the unwanted DC component. The AFE IC includes a DC-coupled instrumentation amplifier (INA), two variable-gain 1st-order low pass filters (LPF) with tunable cut-off frequencies, a fixed gain 2nd-order Sallen-Key high-pass filter (HPF) with tunable cut-off frequencies, a buffer and an 8-bit differential successive approximation register (SAR) ADC. The entire AFE channel is designed and fabricated in a proprietary 0.35-μm CMOS technology. Excluding an external buffer needed to properly drive the ADC, the measured AFE IC consumes only 2.37 μA/channel with an input referred noise of ~40 μVrms in [1 Hz, 1 kHz], and successfully displays proper ECG (electrocardiogram) and electrogram (EGM) waveforms for QRS peaks detection. We expect that the low-power dual-path design of this AFE IC can enable it to periodically record both the AC and the DC signals for proper sensing and calibration for various bio-sensing applications.

To the editor： A 22-year-old man was admitted without significant heart complaint, but with a diagnosis of myocardial infarction at a local hospital. Two months earlier, he suffered blunt chest impact and maxillofacial trauma due to an accident falling from a 3-metero high balcony. He has previously been healthy without any family history of disease. Physical examination on admission revealed mandibular tenderness and a traumatic blindness in the left eye.

经济体制不仅有市场经济体制、计划经济体制两种,还有博彩经济体制、论资排辈经济体制和武力经济体制。在社会运行有序时更多地采用市场经济体制、计划经济体制、博彩经济体制和论资排辈经济体制;当社会处于无序时,武力经济体制则会升格为主要的经济体制。两种社会运行状态下经济体制在实际应用中又是“阴中有阳,阳中有阴”,即当社会总体处于无序状态时,武力经济体制就会升格,同时另外四种社会有序状态下的经济体制还会在部分有序的社会状态中发挥部分作用;当社会总体处于有序状态时,四种社会有序状态下的经济体制就会登场、启动,武力经济体制淡出、隐退,但又会时不时竹笋般冒出来部分作用。社会资源的配置,总是处于五种经济体制的混合作用之下,只是各经济体制所起作用的社会状态、程度或大小不同而已。博彩经济体制、论资排辈经济体制和武力经济体制为何没有同市场经济体制、计划经济体制般成为人类社会基本的经济体制,主要是由于比较经济体制研究领域的空白、这三种经济体制自身的缺陷以及其激励机制所蕴含的理念与人类社会主流的价值观念存在冲突、传统认识的欠缺等。

由美国单方面挑起的贸易争端给中美贸易关系蒙上了一层阴影,中美两国进入了前所未有的贸易摩擦期。依据中美贸易摩擦期间(2017年8月—2020年9月)中国大豆进口贸易的数据,运用复杂网络分析方法,通过进口依存度系数、度与贸易联系、网络结构的均质化分析中国大豆进口贸易网络发生的变化。结果表明:在贸易摩擦期,中国大豆自美进口依存度随中美贸易关系的演进而变化,波动频繁,但总体呈持续下降趋势;中美贸易摩擦并未对中国大豆进口网络的入度造成较大影响,但各节点的联系强度发生了变化,逐渐形成巴西、美国、阿根廷三足鼎立之势;进口网络的均质化受中美贸易摩擦的影响大,贸易关系紧张时,均质化程度低,贸易关系缓和时,均质化程度提高。根据仍存在的风险,建议中国在扩大进口来源的同时,降低从高风险地区的进口,通过调整饮食消费结构和增加本国供给能力以防范风险,形成中国大豆的安全稳定进口网络,保证中国经济安全、平稳、健康发展。

当前国有银行改革存在利益沾滞并陷入了胶着状态 ,已被锁定于低效的劣等均衡 ;内生于经济、金融制度变迁过程中的政府行政干预机制是国有银行改革的最大阻力 ,也是国有银行改革掉入陷阱的诱因。因此 ,破除行政干预机制 ,尽快转变政府职能是其他各项改革成功推进的前提 ,也是提升整体经济素质的前提 ;而培育良好的市场环境、提供及时准确的信息引导、做一个“客户导向型”政府 ,则是政府职能在经济领域的集中体现。
