| 1 | Effect of nitrogen on corrosion behaviour of a novel high nitrogen medium-entropy alloy CrCoNiN manufactured by pressurized metallurgy显示文摘A novel high nitrogen medium-entropy alloy CrCoNiN, which had higher strength and slightly lower ductility than CrCoNi alloy, was successfully manufactured by pressurized metallurgy. The microstructure and corrosion behaviour were investigated by microscopic, electrochemical and spectroscopic methods.The results indicated that nitrogen existed in the form of Cr_2N precipitates and uniformly distributed N atoms, and nitrogen alloying significantly refined the grain size. Besides, nitrogen enriched on the outmost surface of passive film and metal/film interface as ammonia(NH-_3 and NH_4^+) and CrN, respectively. The significant improvement of corrosion resistance of CrCoNiN was attributed to the lower metastable pitting susceptibility together with thicker, less defective and more compact passive film. | Hao Feng Huabing Li Xiaolei Wu Zhouhua Jiang Si Zhao Tao Zhang Dake Xu Shucai Zhang Hongchun Zhu Binbin Zhang Muxin Yang | 2018 | Journal of Materials Science & Technology2018，34，10： | 8 |
| 2 | Amorphous alloys for electrocatalysis:The significant role of the amorphous alloy structure显示文摘Amorphous alloys,also known as metallic glasses,are solid metallic materials having long-range disordered atomic structures.Compared to crystalline alloys,amorphous alloys not only have metallic characters,but also possess several distinct properties associated to the amorphous structure,such as isotropy,composition flexibility,unsaturated surface,etc.As a result,amorphous alloys offer a class of highly promising materials for catalyzing electrochemical reactions.In this minireview,the preparation,characterization and electrocatalytic performances of a variety of metallic amorphous alloy materials are summarized.The influences of the amorphous alloy structure on different electrochemical reactions are discussed.Finally,a summary on the advantages and challenges of amorphous alloys in electrocatalysis is provided,along with some perspectives about the future research directions. | Xingyun Li Weizheng Cai Dong-Sheng Li Jun Xu Huabing Tao Bin Liu | 2023 | Nano Research2023，16，4： | 3 |
| 3 | Low sample volume origami-paper-based graphene-modified aptasensors for label-free electrochemical detection of cancer biomarker-EGFR显示文摘In this work,an electrochemical paper-based aptasensor was fabricated for label-free and ultrasensitive detection of epidermal growth factor receptor(EGFR)by employing anti-EGFR aptamers as the bio-recognition element.The device used the concept of paper-folding,or origami,to serve as a valve between sample introduction and detection,so reducing sampling volumes and improving operation convenience.Amino-functionalized graphene(NH 2-GO)/thionine(THI)/gold particle(AuNP)nanocomposites were used to modify the working electrode not only to generate the electrochemical signals,but also to provide an environment conducive to aptamer immobilization.Electrochemical characterization revealed that the formation of an insulating aptamer–antigen immunocomplex would hinder electron transfer from the sample medium to the working electrode,thus resulting in a lower signal.The experimental results showed that the proposed aptasensor exhibited a linear range from 0.05 to 200 ngmL^(−1)(R^(2)=0.989)and a detection limit of 5pgmL^(−1) for EGFR.The analytical reliability of the proposed paper-based aptasensor was further investigated by analyzing serum samples,showing good agreement with the gold-standard enzyme-linked immunosorbent assay. | Yang Wang Shuai Sun Jinping Luo Ying Xiong Tao Ming Juntao Liu Yuanyuan Ma Shi Yan Yue Yang Zhugen Yang Julien Reboud Huabing Yin Jonathan MCooper Xinxia Cai | 2020 | Microsystems & Nanoengineering2020，6，1： | 2 |
