| 1 | Thermodynamic and Kinetic Analysis of Low-temperature Thermal Reduction of Graphene Oxide显示文摘The thermodynamic state and kinetic process of low-temperature deoxygenation reaction of graphene oxide(GO) have been investigated for better understanding on the reduction mechanism by using Differential Scanning Calorimetry(DSC), Thermogravimetry-Mass Spectrometry(TG-MS), and X-ray Photoelectron Spectroscopy(XPS). It is found that the thermal reduction reaction of GO is exothermic with degassing of CO_2, CO and H_2O. Graphene is thermodynamically more stable than GO. The deoxygenation reaction of GO is kinetically controlled and the activation energy for GO is calculated to be 167 k J/mol(1.73 e V/atom). | Kuibo Yin Haitao Li Yidong Xia Hengchang Bi Jun Sun Zhiguo Liu Litao Sun | 2011 | Nano-Micro Letters2011，3，1： | 1 |

| 3 | Facile fabrication of paper-based flexible thermoelectric generator显示文摘Paper,as a foldable,pollution-free,and low-cost material,has become a suitable support substrate for producing flexible thermoelectric(TE)generators to realize waste heat recycling and the application of human-powered electronic devices.We propose a facile fabrication method to modify cellulose paper with inorganic TE powders via vacuum filtration,making a modified paper that possesses good thermoelectric properties.By connecting the modified paper to copper foils,flexible paper-based TE generators(PTGs)are fabricated.The obtained PTG with three units of P–N modules can generate an output voltage of∼41.2 mV at a temperature difference of 50 K.Based on this modified paper,a thermal sensor that responds to heat sources,such as fingers,is proposed with a rapid response time of 0.25 s.This work offers a promising strategy for the simple fabrication of PTGs,paving the way for achieving the commercial application of self-powered wearable electronics. | Zuoyuan Dong Hua Liu Xin Yang Jichen Fan Hengchang Bi Chaolun Wang Yonghua Zhang Chen Luo Xinqian Chen Xing Wu | 2021 | npj Flexible Electronics2021，5，1： | 1 |
