| 1 | Recent progress in 2D materials for flexible supercapacitors显示文摘High performance supercapacitors coupled with mechanical flexibility are needed to drive flexible and wearable electronics that have anesthetic appeal and multi-functionality. Two dimensional(2D) materials have attracted attention owing to their unique physicochemical and electrochemical properties, in addition to their ability to form hetero-structures with other nanomaterials further improving mechanical and electrochemical properties. After a brief introduction of supercapacitors and 2D materials, recent progress on flexible supercapacitors using 2D materials is reviewed. Here we provide insights into the structure–property relationships of flexible electrodes, in particular free-standing films. We also present our perspectives on the development of flexible supercapacitors. | Yan Han Yu Ge Yunfeng Chao Caiyun Wang Gordon G.Wallace | 2018 | Journal of Energy Chemistry2018，27，1： | 11 |
| 2 | High-quality aluminum turbocharger impellers produced by thixocasting显示文摘The thixocasting process was chosen to produce the impellers as it is capable of producing castings with extremely high internal quality.Slugs cut from the DC cast bars are re-heated to the semi-solid casting temperature, and a specially-designed runner and gating system is used to prevent oxide from the surface of the slugs from becoming incorporated into the impeller.The technology used to produce the semi-solid impellers is described in detail.The semi-solid cast impellers, produced from an Al-Si-Mg-Cu alloy, are heat treated to the T6 temper.Results from testing are presented demonstrating that the impellers are free of porosity and other internal defects.Both mechanical property and fatigue data are presented showing that the semi-solid impellers have better properties than impellers produced by conventional casting and similar properties to forged and machined impellers.A short study is also described which identified suitable processing parameters to minimize hot tearing in the complex-shaped turbocharger impellers semi-solid cast from alloy 201.The surfaces of the impellers were examined using penetrant testing, and the results of modifying processing parameters on the propensity for surface cracking are presented.An aging study was performed to identify optimum mechanical strength. | G.WALLACE A.P.JACKSON S.P.MIDSON Q.ZHU | 2010 | Transactions of Nonferrous Metals Society of China2010，20，9： | 3 |
| 3 | Metal porphyrin intercalated reduced graphene oxide nanocomposite utilized for electrocatalytic oxygen reduction显示文摘In this paper, we report a simple and facile self-assembly method to successfully fabricate cationic metal porphyrin-MtTMPyP(Mt= Cobalt(Ⅱ), Manganese(Ⅲ), or Iron(Ⅲ); TMPyP = 5, 10, 15, 20-tetrakis(N-methylpyridinium-4-yl) porphyrin) intercalated into the layer of graphene oxide(GO) by the cooperative effects of electrostatic and π-π stacking interaction between positively charged metal porphyrin and negatively charged GO sheets. Followed by reduction with hydrazine vapor, a series of novel 2 D MtTMPyP/rGO_n were fabricated. The as-prepared 2 D hybrids were fully characterized and tested as non-noble metal catalysts for oxygen reduction reaction(ORR) in an alkaline medium. The MtTMPyP/rGO_n hybrids, especially CoTMPyP/rGO_5, demonstrated an improved electrocatalytic activity for ORR and a number of exchanged electrons close to 4-electron reaction, increased stability and excellent tolerance to methanol, showing a potential alternative catalyst for ORR in fuel cells and air batteries. | Mingyan Wang Qing Wang Wei Zhu Ying Yang Huixian Zhou Fan Zhang Lihua Zhou Joselito M.Razal Gordon G.Wallace Jun Chen | 2017 | Green Energy & Environment2017，2，3： | 3 |
| 4 | Three-dimensional bioprinting speeds up smart regenerative medicine显示文摘Biological materials can actively participate in the formation of bioactive organs and can even control cell fate to form functional tissues that we name as the smart regenerative medicine(SRM). The SRM requires interdisciplinary efforts to finalize the pre-designed organs. Three-dimensional(3D) printing, as an additive manufacturing technology, has been widely used in various fields due to its high resolution and individuation. In SRM, with the assistance of 3D printing, cells and biomaterials could be precisely positioned to construct complicated tissues. This review summarizes the state of the SRM advances and focuses in particular on the 3D printing application in biofabrication. We further discuss the issues of SRM development and finally propose some approaches for future 3D printing, which involves SRM. | Qi Gu He Zhu Jing Li Xia Li Jie Hao Gordon G.Wallace Qi Zhou | 2016 | National Science Review2016，3，3： | 2 |

| 8 | Scale up of reactors for carbon dioxide reduction显示文摘In recent times there has been a great deal of interest in the conversion of carbon dioxide into more useful chemical compounds.On the other hand,the translation of these developments in electrochemical reduction of carbon dioxide from the laboratory bench to practical scale remains an underexplored topic.Here we examine some of the major challenges,demonstrating some promising strategies towards such scale-up,including increased electrode area and stacking of electrode pairs in different configurations.We observed that increasing the electrode area from 1 to 10 cm^(2) led to only a 4%drop in current density,with similarly small penalties realised when stacking sub-cells together. | Andrew Nattestad Klaudia Wagner Gordon G.Wallace | 2023 | Frontiers of Chemical Science and Engineering2023，17，1： | 0 |
