Particling Night: The Design of an Emerging Media Artwork as a Tool for Reflection on Superficiality of Social Media
No full textThis study explores the potential of interactive media art to promote reflection on ourselves living in social networks. The prevalence of social media platforms has increased our social connections, yet research suggests a rise in loneliness and isolation. We created an interactive media artwork using speech-to-text technology and generative visualization to reflect on the meaning of relationships in the age of digitized human connections as well as the superficiality of social media networks we developed. User surveys and observations revealed that our artwork helped our audience to have reflection through artistic experiences. The findings suggest that multi-modal art experiences and embodied design components can provide better opportunities for one???s reflection process. This study can contribute to the design and evaluation of future emerging media artworks that can support individuals??? reflection process on various humane issues caused by emerging technology

No full textCathode electrode architecture with facile ion percolating network assuring interfacial integrity for high-performance solid-state batteries
No full textAlthough solid-state batteries (SSBs) are promising next-generation energy-storage devices owing to their high safety and energy density, their wide application is hindered by critical issues such as poor power density and rapid performance degradation. These issues are related to the limit of electronic and lithium percolation networks with imperfect solid-solid interfacial contact. This study develops an optimal strategy to facilitate an iontransport network by designing a simple core-shell-like cathode covered by an inorganic solid electrolyte (garnet-type Li6.25Ga0.25La3Zr2O12) for polymer-based SSBs, ensuring the high capacity, high rate capability, and long-term cycle stability even in practical pouch cell at room temperature. Encapsulated cathode electrode architecture via a simple dry-coating strategy provides a percolating network for facile ionic conduction, assuring the homogeneous reaction in the cathode electrode. It alleviates not only the mechanical degradation of the cathode electrode but also the subsequent crosstalk effect on the anode-solid electrolyte interface. Our study highlights that the design of the cathode architecture considering the ion-conducting network is crucial to secure the high performance of polymer-based SSBs by maintaining the interfaces intact with solid electrolytes in both the cathode and anode interfaces
Conductance stable and mechanically durable bi-layer EGaIn composite-coated stretchable fiber for 1D bioelectronics
No full textDeformable semi-solid liquid metal particles (LMP) have emerged as a promising substitute for rigid conductive fillers due to their excellent electrical properties and stable conductance under strain. However, achieving a compact and robust coating of LMP on fibers remains a persistent challenge, mainly due to the incompatibility of conventional coating techniques with LMP. Additionally, the limited durability and absence of initial electrical conductivity of LMP restrict their widespread application. In this study, we propose a solution process that robustly and compactly assembles mechanically durable and initially conductive LMP on fibers. Specifically, we present a shearing-based deposition of polymer-attached LMP followed by additional coating with CNT-attached LMP to create bi-layer LMP composite with exceptional durability, electrical conductivity, stretchability, and biocompatibility on various fibers. The versatility and reliability of this manufacturing strategy for 1D electronics are demonstrated through the development of sewn electrical circuits, smart clothes, stretchable biointerfaced fiber, and multifunctional fiber probes
The Effects of In-Stream Video Advertising on Ad Information Encoding: A Neurophysiological Study
No full textAlthough in-stream video advertising is common, its effects on advertisement (ad) information encoding remain unclear. We investigated the effects of in-stream video advertising by comparing two groups: those watching mid-roll (between the program) ads and those watching pre- and post-roll (before and after the program, respectively) ads. To elucidate how advertising content is encoded in the context of in-stream video advertising, we integrated two theoretical frameworks: the negative emotion-memory model (NEMM) and the limited capacity model of motivated-mediated message processing (LC4MP). We used electroencephalography (EEG) to assess negative emotions and bottom-up attention during advertisement viewing. The findings indicate that the first mid-roll ad induced negative emotions, but these feelings were attenuated during subsequent mid-rolls. In addition, negative emotions induced by mid-roll ads attenuated the role of bottom-up attention in the information encoding process. However, the pre- and post-roll ads were not accompanied by negative emotions; thus, bottom-up attention played a major role in the information encoding of these ads. The results also suggest that despite the negative emotions experienced during mid-rolls, such transient negative reactions did not affect purchase intention for the advertised products
Systematic investigation of coupling between symmetric and antisymmetric stretches of D2O in CHCl3 by 2D IR
No full textThe coupling between the symmetric (v(s)) and antisymmetric (v(a)) OD stretch modes of monomeric D2O in CHCl3 is investigated using polarization-dependent two-dimensional infrared (2D IR) spectroscopy supported by numerical 2D IR simulations based on the exciton-band theory. The relationship between the local modes' and the exciton states' parameters is systematically studied, including center frequencies, diagonal anharmonicities, coupling, and off-diagonal anharmonicity. The mean coupling between v(s) and v(a) is accurately evaluated to be -49.96 +/- 0.14 cm(-1). The degree of relaxation in the harmonic approximation is quantified, and the angle between the exciton-state dipoles is accurately evaluated to be 101.4 degrees +/- 3.6 degrees. In addition, the effect of the local-mode frequency correlation on the resulting exciton-state frequency correlation and the spectral shape of the linear and 2D IR spectra are also investigated
Direct measurements of the colloidal Debye force
No full textThe Debye interaction is defined as the attraction between a polar molecule and a nonpolar molecule, which governs many self-assembling processes in materials. Here, Lee et al. design a like-charged colloidal model at the water-oil interface to characterize the Debye interaction for the first time. Colloids often behave in a manner similar to their counterparts in molecular space and are used as model systems to understand molecular behavior. Here, we study like-charged colloidal attractions between a permanent dipole on an interfacial particle and its induced dipole on a water-immersed particle caused by diffuse layer polarization. We find that the scaling behavior of the measured dipole-induced dipole (D-I) interaction via optical laser tweezers is in good agreement with that predicted from the molecular Debye interaction. The dipole character propagates to form aggregate chains. Using coarse-grained molecular dynamic simulations, we identify the separate roles of the D-I attraction and the van der Waals attraction on aggregate formation. The D-I attraction should be universal in a broad range of soft matter, such as colloids, polymers, clays, and biological materials, motivating researchers to further conduct in-depth research on these materials
Organoid???Based Human Stomach Micro???Physiological System to Recapitulate the Dynamic Mucosal Defense Mechanism
No full textSeveral stomach diseases are attributed to the dysregulation of physiological function of gastric mucosal barrier by pathogens. Gastric organoids are a promising tool to develop treatment strategies for gastric infections. However, their functional features of in vivo gastric mucosal barrier and host???microbe interactions are limited due to the lack of physiological stimuli. Herein, a human stomach micro-physiological system (hsMPS) with physiologically relevant gastric mucosal defense system is described based on the combination of organoid and MPS technology. A fluid flow enhanced epithelial-mesenchymal interaction in the hsMPS enables functional maturation of gastric epithelial cells, which allows for the recreation of mesh-like mucus layer containing high level of mucus protective peptides and well-developed epithelial junctional complexes. Furthermore, gastroprotection mechanisms against Helicobacter pylori (H. pylori) are successfully demonstrated in this system. Therefore, hsMPS represents a new in vitro tool for research where gastric mucosal defense mechanism is pivotal for developing therapeutic strategies
