A new technique for single molecular peptide sequencing is demonstrated by translocation of ssDNA-conjugated-peptide through MspA nanopore which is regulated by a DNA helicase motor.
Due to the wide application of wearable electronic devices in daily life, research into flexible electronics has become very attractive. Recently, various polymer-based sensors have emerged with great sensing performance and excellent extensibility. It is well known that different structural designs each confer their own unique, great impacts on the properties of materials. For polymer-based pressure/strain sensors, different structural designs determine different response-sensing mechanisms, thus showing their unique advantages and characteristics. This paper mainly focuses on polymer-based pressure-sensing materials applied in different microstructures and reviews their respective advantages. At the same time, polymer-based pressure sensors with different microstructures, including with respect to their working mechanisms, key parameters, and relevant operating ranges, are discussed in detail. According to the summary of its performance and mechanisms, different morphologies of microstructures can be designed for a sensor according to its performance characteristics and application scenario requirements, and the optimal structure can be adjusted by weighing and comparing sensor performances for the future. Finally, a conclusion and future perspectives are described.
The gamification of sustainable consumption is receiving more and more attention from both academic and business circles. However, there is still a lack of research on the incentive mechanism and evaluation of gamification design to promote sustainable consumption behavior. Taking the gamified apps that promote sustainable consumption in China as an example, this study attempts to explore the incentive mechanism of gamification application for sustainable consumption by using the “stimulus-organism-response” model. Furthermore, it also constructs an evaluation index system of gamification design for sustainable consumption app and identifies the key factors in the gamification design by using the analytic hierarchy process. The results suggest that gamification apps use game elements and game mechanism frameworks to build a new sustainable consumption context for users, which breaks the boundary between reality and virtuality, and enables users to gain real-life value for their behavior in the virtual world. Moreover, the trust mechanism and socialized contextual experience of the gamified apps further strengthen this sense of connectedness and interaction, and enhance the user's motivation for sustainable consumption. In the gamification design of sustainable consumption app, more attention needs to be paid to the implementation effect behind gamification, that is, to promote the cultivation of public sustainable consumption values and lifestyle. This study advances theoretical and practical understanding of the gamification of sustainable consumption. The results can also be used as a starting base for the development and design of gamified apps in the sustainable consumption field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
