摘要：In the past oral Caribbean and African cultures,performances by the“griots”reminded the community of its heroic *** colonial studies,performance is a way for the colonized people to reconnect with its original soul and language and to become magnificent of creativity like the storyteller Solibo in Chamoiseau’s Solibo Magnifique(Caribbean).In Chamoiseau’s novel,the Black policemen who came to investigate on Solibo’s sudden death during the performance look *** mimic the French colonizers with their“baton”and their racism at thinking evil of the Black community and they provoke *** and the irony it conveys,subverts the formerly ironclad authority of the colonial order(Homi *** in Location of Culture).The Cameroonian writer Werewere Liking-Gnépo also warns the Africans of the danger of wearing the White Mask of the colonizers(like Fanon in Black Skin,White Masks).She demonstrates in her Song/Novel She will be of Jasper and Coral,that while the African Mask empowers the performer of metaphysical powers,the White Mask of colonialism on the contrary weakens the performer who internalizes his inferiority and becomes complicit of his ***,Werewere Liking-Gnépo shows ithat the White Mask of colonialism can be used to mimic the harshness and corruption of the Colonial order and in doing so to bring back regeneration of Africa.

摘要：Significant enhancement of energy density of electrical double layered capacitors is a major challenge for electrochemical capacitors to conquer the emerging field of large scale renewable energy *** enhancement of specific capacitance is an effective strategy to obtain higher energy *** of redox mediator in the electrolyte as pseudocapacitive sources could enhance the specific capacitance,but well-coupled electrode materials should be developed as ***,as a proof-of-concept experiment,N,O-codoped porous carbon nanosheets have been fabricated,wherein graphene oxide is employed as both oxygen source as well as structure directing ***,the obtained electrode materials endow electrical double layered capacitors with excellent capacitive performances,including the ultra-high specific capacitance(5073.5 F g^(-1))and excellent cycling stability,which could be attributed to the synergy of morphology and surface chemistry of N,O-codoped porous carbon *** results would form the basis for an unprecedented perspective in the development of next generation electrode materials for electrical double layered capacitors.
