This monograph investigates 15 L2 creative writers’ social constructive power in identity constructions. Through interviews and think-aloud story writing sessions, the central study considers how L2 writer voices are mediated by the writers’ autobiographical identities, namely, their sense of selves formulated by their previous language learning and literacy experiences. The inquiry takes the epistemological stance that L2 creative writing is simultaneously a cognitive construct and a social phenomenon and that these two are mutually inclusive. The study contributes to L2 creative writing research and L2 learner identity research and will be of benefit to researchers, language teachers and writing instructors who wish to understand creative writing processes in order to help develop their students’ positive self-esteem, confidence, motivation and engagement with the L2.

In this monograph, the graphene-based field-effect transistor (FET) biosensors are shown to be an emerging sensing platform. Divided into two parts the first set of chapters are devoted to basic knowledge of graphene, graphene FET and its biosensing. In the second part of this book the applications of graphene FET biosensors combined with various biotechnologies are presented. As well as discussing the existing technologies the authors also introduce their own ideas and concepts. Finally the remaining problems in graphene FET biosensors are discussed, along with proposed solutions and prospects for future applications. This monograph allows readers to grasp the basic knowledge and future direction of graphene-based FET biosensors.

Electro-membrane processes using ion-exchange membranes have been widely used in numerous applications, such as electrodialytic demineralization of saline water, treatment of industrial effluents. However, the presence of multivalent ions, such as CO32-, SO42- or Ca2+, Mg2+ may result in a detrimental risk of membrane scaling, which in turn hinder the membrane performance, for instance, decreasing the current efficiency and increasing the energy consumption. In order to improve these defects, ion-exchange membranes with specific selectivity for particular ions, like mono-valent membranes, may solve these problems. Although Astom claimed they had already produced high performance mono-valent selective membrane, there are few research focusing on this topic. Thus, the fundamental research is very important for ion-exchange membrane development. In addition, prevention of ion-exchange membrane fouling is one of the essential problems to overcome in their design and operation. Fouling causes deterioration in the membrane performance such as a decline in the ions flux and an increase in the electric resistance. In this case, development of mono-valent and antifouling ion exchange membranes with high-selectivity and low cost is meaningful and urgently required. Besides, remaining challenges include prolonging the life-span of the membrane, scale-up the use and keeping the stability is also needed to be solved. The PhD study aims at understanding the separation mechanism of the mono-valent and antifouling ion exchange membrane in aqueous solutions by responding to the challenges mentioned above. Preparation and characterization of mono-valent and antifouling ion exchange membranes will be studied at a pilot scale including different methods and materials to prepare mono-valent and antifouling membranes. Application of the membranes will be focused on the sea water concentration accompanying with the use of the mono-valent cation and anion ion exchange membranes. Antifouling property of ion exchange membranes will be studied concerning different kinds of solution including sea water, industrial effluents. Stability and membrane surface resistance of the newly developed membranes are the two main characteristics that needed to be considered during the operation.
