Tripotassium citrate monohydrate derived carbon nanosheets as a competent assistant to manganese dioxide

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 3, Pages 420-432 doi: 10.1007/s11705-021-2065-7

Abstract: Production cost, capacitance, and electrode materials safety are the key factors to be concerned about for supercapacitors. In this work, a type of carbon nanosheets was produced through the carbonization of tripotassium citrate monohydrate and nitric acidification. Subsequently, a well-designed manganese dioxide/carbon nanosheets composite was synthesized through hydrothermal treating. The carbon nanosheets served as the substrate for growing the manganese dioxide, regulating its distribution, and preventing it from inhomogeneous dimensions and severe agglomeration. Many manganese dioxide nanosheets grew vertically on the numerous functional groups generated on the surface of the carbon nanosheets during acidification. The synergistic combination of carbon nanosheets and manganese dioxide tailors the electrochemical performance of the composite, which benefits from the excellent conductivity and stability of carbon nanosheets. The carbon nanosheets derived from tripotassium citrate monohydrate are conducive to the remarkable performance of manganese dioxide/carbon nanosheets electrode. Finally, an asymmetric supercapacitor with active carbon as the cathode and manganese dioxide/carbon nanosheets as the anode was assembled, achieving an outstanding energy density of 54.68 Wh·kg^–1 and remarkable power density of 6399.2 W·kg^–1 superior to conventional lead-acid batteries. After 10000 charge-discharge cycles, the device retained 75.3% of the initial capacitance, showing good cycle stability. Two assembled asymmetric supercapacitors in series charged for 3 min could power a yellow light emitting diode with an operating voltage of 2 V for 2 min. This study may provide valuable insights for applying carbon materials and manganese dioxide in the energy storage field.

Shuyue LI, Jiaqi GUO, Yan GAO, Jianguang LOU, Dejian YANG, Yan XIAO, Yadong ZHOU, Ting LIU,lishuyue1221@stu.xjtu.edu.cn,jasperguo2013@stu.xjtu.edu.cn,yan.gao@microsoft.com,jlou@microsoft.com,dejian.yang@microsoft.com,yan.xiao@microsoft.com,ydzhou@xjtu.edu.cn,tingliu@mail.xjtu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 5, Pages 749-762 doi: 10.1631/FITEE.2100467

Abstract: Task-oriented s are software systems that provide users with a natural language interface to complete domain-specific tasks. With the recent technological advances in natural language processing and , an increasing number of task-oriented s have been developed. However, due to the well-known complexity and difficulties of the natural language understanding problem, it is challenging to manage a task-oriented software project. Meanwhile, the management and experience related to the development of s are hardly studied or shared in the research community or industry, to the best of our knowledge. To bridge this knowledge gap, in this paper, we share our experience and the lessons that we have learned at managing a task-oriented software project at Microsoft. We believe that our practices and the lessons learned can provide a useful reference for other researchers and practitioners who aim to develop a system. Finally, we have developed a requirement management tool, named SpecSpace, which can facilitate the management of projects.

From Eliza to XiaoIce: challenges and opportunities with social chatbots Review

Heung-yeung SHUM, Xiao-dong HE, Di LI

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 1, Pages 10-26 doi: 10.1631/FITEE.1700826

Abstract: Conversational systems have come a long way since their inception in the 1960s. After decades of research and development, we have seen progress from Eliza and Parry in the 1960s and 1970s, to task-completion systems as in the Defense Advanced Research Projects Agency (DARPA) communicator program in the 2000s, to intelligent personal assistants such as Siri, in the 2010s, to today’s social chatbots like XiaoIce. Social chatbots’ appeal lies not only in their ability to respond to users’ diverse requests, but also in being able to establish an emotional connection with users. The latter is done by satisfying users’ need for communication, affection, as well as social belonging. To further the advancement and adoption of social chatbots, their design must focus on user engagement and take both intellectual quotient (IQ) and emotional quotient (EQ) into account. Users should want to engage with a social chatbot; as such, we define the success metric for social chatbots as conversation-turns per session (CPS). Using XiaoIce as an illustrative example, we discuss key technologies in building social chatbots from core chat to visual awareness to skills. We also show how XiaoIce can dynamically recognize emotion and engage the user throughout long conversations with appropriate interpersonal responses. As we become the first generation of humans ever living with artificial intelligenc (AI), we have a responsibility to design social chatbots to be both useful and empathetic, so they will become ubiquitous and help society as a whole.
