      • A Novel Multiple Attribute Decision Making Method and its Application in Sustainable Assessment

        Xue-ying Di,Chai Hua,Jiang Shihui,Han Jiye,Song Guomei 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.2

        It is a key point for an enterprise in the long run whether it has an ability to achieve sustainability development. Therefore, it is important to assess this ability from the perspective of an enterprise. In this paper, a new multiple attribute decision making method in the dual hesitant fuzzy context is proposed to deal with this problem. Dual hesitant fuzzy set, as a combination of intuitionistic fuzzy set and hesitant fuzzy set, can describe the complex preferences of the decision maker or experts more accurately where membership, non-membership and uncertainty is included simultaneously. Distance measure is introduced in TOPSIS to measure the difference between two alternatives in this assessment problem, which forms the multiple attribute decision making method. Finally, an illustrative example is demonstrated to verify the applicability of the proposed method.

        Synthesis of heteroatom and metallic compound self-co-doped porous carbon derived from swine manure for supercapacitor electrodes and lead ion adsorbents

        Liyuan Qin,Yang Wua,Zhiwei Hou,Shihui Zhang,Enchen Jiang 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.102 No.-

        Swine manure activated carbon (SMAC) with self-co-doped metallic compounds and heteroatoms wasprepared by combining KOH activation with pyrolysis. The structure, electrochemical performance andadsorption of SMACs prepared with various activation temperatures, activation times, alkali-carbonratios and pickling steps were investigated. A hierarchical pore structure existed in all the SMACs, whichshowed excellent and significantly different properties, including a specific capacitance of 278 F/g, and ahigh SSA of 2321 m2/g (SMACHF), which retained 100% of its capacitance after 10,000 cycles at 5 A/g and aPb2+ adsorption capacity of 211.8 mg/g at room temperature (SMACNON). The SMACs contained heteroatomfunctional groups and Si, Ca and Mg compounds, which did not produce pseudocapacitors but didincrease the Pb2+ adsorption capacity and electrochemical cycling stability. The Pb2+ adsorption capacitiesof SMACNON, SMACPHF and SMACHF corresponded to the effect of the functional group content ratherthan the effect of the SSA. These porous carbons were derived from inexpensive swine manure, combinesuitable porosity with metallic elements and heteroatom doping, and have promising uses in multifunctionalapplications.
