Advances in material science and nanotechnology have fostered the miniaturization of devices. Over the past two decades, the form-factor of these devices has evolved from 3D rigid, volumetric devices through 2D film-based flexible electronics, finally to 1D fiber electronics (fibertronics). In this regard, fibertronic strategies toward wearable applications (e.g., electronic textiles (e-textiles)) have attracted considerable attention thanks to their capability to impart various functions into textiles with retaining textiles' intrinsic properties as well as imperceptible irritation by foreign matters. In recent years, extensive research has been carried out to develop various functional devices in the fiber form. Among various features, lighting and display features are the highly desirable functions in wearable electronics. This article discusses the recent progress of materials, architectural designs, and new fabrication technologies of fiber-shaped lighting devices and the current challenges corresponding to each device's operating mechanism. Moreover, opportunities and applications that the revolutionary convergence between the state-of-the-art fibertronic technology and age-long textile industry will bring in the future are also discussed. 相似文献

Despite tellurium being less abundant in the Earth's crust than gold, platinum, or rare‐earth elements, the number of industrial applications of tellurium has rapidly increased in recent years. However, to date, many properties of tellurium and its associated compounds remain unknown. For example, formation mechanisms of many tellurium nanostructures synthesized so far have not yet been verified, and it is unclear why tellurium can readily transform to other compounds like silver telluride by simply mixing with solutions containing silver ions. This uncertainty appears to be due to previous misunderstandings about the tellurium structure. Here, a new approach to the tellurium structure via synthesized structures is proposed. It is found that the proposed approach applies not only to these structures but to all other tellurium nanostructures. Moreover, some unique tellurium nanostructures whose formation mechanism are, until now, unconfirmed can be explained. 相似文献

While driving research on affect has mostly focused on anger and road rage, there has been little empirical research on other affective states. Affect researchers widely acknowledge the “sadder but wiser” phenomenon, but there is little evidence if this tendency can be applied to the driving environment as well. The objective of the present study is to empirically test whether sadness enhances driving performance as the sadder but wiser notion might predict or sadness impairs driving performance as its negative valence or low arousal dimension might predict. The study consists of a simulated driving experiment with induced anger, sadness, and neutral affect to examine how anger and sadness influence driving-related risk perception, driving performance, and perceived workload. Sixty-one young drivers drove under three different road conditions with either induced anger, sadness, or neutral affect conditions. After affect induction, there was no difference in subjective risk perception across three affect conditions. However, participants in both affect conditions showed significantly more errors and took longer driving time than those in the neutral condition. Only participants with induced anger reported significantly higher physical workload and frustration than participants with neutral affect. Results are discussed in terms of affect mechanisms, design directions for the in-vehicle affect mitigation system, and limitations of the study. 相似文献

We investigated the electronic perturbation between graphene oxide and cobalt porphyrin to reveal the origin of the enhanced electrocatalytic activity of a hybrid complex using time-resolved spectroscopic measurements and theoretical calculations. The impulsively generated charge-separated state, GO−-(CoIIAPFP)+, undergoes fast charge recombination (<10 ps) between GO− and (CoIIAPFP)+ moieties. This fast charge recombination is directly related to the quick neutralization of (CoIIAPFP)+, which shortens the dead time of inactive CoIIIAPFP after the electrocatalytic reduction reaction. The fast transformation of inactive CoIIIAPFP to active CoIIAPFP is an important factor in the enhanced electrocatalytic activity of the hybrid complex. 相似文献
