A novel method for Isolating Nanocrystalline Cellulose from Eucalyptus Hardwood

引用

Journal of Analytical Sciences, Methods and Instrumentation 2019年第3期9卷 51-62页

作者： jinrong zhang Wenbo Zou The High School Affiliated to Renmin University of China Beijing China National Institutes for Food and Drug Control Beijing China

The objective of this work is to develop a new method for extracting nanocrystalline cellulose (CNC) from eucalyptus. CNC was isolated from eucalyptus using 6:4 (v/v) tetrahydrofuran/water. The chemical and crystalline structure of the isolated CNC was characterized by zeta potential measurements, Fourier Transform Infrared (FT-IR) and UV-Vis spectroscopies, and X-ray powder diffractometry. The CNC morphology was characterized by Transmission Electron Microscope (TEM) and particle size of CNC was determined by the Dynamic Light Scattering (DLS) method. Cytotoxicity and zebrafish-toxicity experiments were also performed on CNC. The yield of CNC using the new extraction method was about 41%, and the extracted CNC particles were about 20 nm in diameter and about 40 nm long, on average. The zeta potential of the CNC was determined to be -56 eV and the CN particles were uniformly distributed in a suspension of 0.5 wt%. The prepared CNC was a type I polymorph with an intact crystal structure. Toxicity results revealed that 0.5 wt% is a safe CNC concentration, and that 2.5 mg/mL CNC is not teratogenic or lethal to zebrafish embryos or juveniles. The new extraction method developed in this study is environmentally friendly, and easy to operate with relatively low cost.

针对基于最小高斯频移键控+伪码(pseudo-noise code,PN)测距的遥外测体制存在遥测数据和测距信号相互干扰问题,提出一种干扰抑制方法。接收机在遥测解调前,通过负反馈环路将本地重新生成的测距信号与接收信号进行相关处理,去除接收信号中的测距信号,以提高遥测信号信噪比;遥测数据解调后进行信道译码,降低误码率,提高重建的测距信号质量。经仿真得到了遥测误码率、PN捕获时间和测距精度。结果表明,采用干扰抑制方法后,有效抑制了测距信号对遥测的干扰,减小了遥测误码对测距性能的影响,提高了遥测误码率性能、PN捕获性能和测距精度。

试析后冷战时期中国加强东亚地区合作的动因

引用

当代亚太 2006年第4期 13-18页

作者：张金荣外交学院国际关系研究所

本文认为,后冷战时期中国加强东亚地区合作,是由于东亚地区彼此的认知结构发生变化,导致中国对自我身份重新定位,中国的国家利益随之扩展。由此,中国加强东亚地区合作,给东亚地区带来的是和平与安全,而非动荡与威胁。
