With the rise of the contact-free era, consumers enjoy shopping via virtual reality (VR) without any physical constraints. The expansion of a sensory shopping experience via VR can enrich consumers' positive emotions and stimulate their imagination and creative thinking. However, there is a lack of research exploring the role of VR in enhancing consumer creativity in the context of shopping. This study aims to investigate the mechanism between the VR shopping experience and consumer creativity. Specifically, ...

Design of bifunctional multimetallic alloy catalysts, which are one of the most promising candidates for water splitting, is a significant issue for the efficient production of renewable energy. Owing to large dimensions of the components and composition of multimetallic alloys, as well as the trade-off behavior in terms of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) overpotentials for bifunctional catalysts, it is difficult to search for high-performance bifunctional ...

We introduce an advanced ultrahigh-resolution (∼ 15 nm) patterning technique that enables the fabrication of various 3D high aspect ratio multicomponents/shaped nanostructures. This methodology utilizes the repetitive secondary sputtering phenomenon under etching plasma conditions and prepatterned fabrication control. The secondary sputtering phenomenon repetitively generates an angular distribution of target particles during ion-bombardment. This method, advanced repetitive secondary sputtering lithography, ...

High-resolution (10 nm), high-areal density, high-aspect ratio (>5), and morphologically complex nanopatterns are fabricated from a single conventional block copolymer (BCP) structure with a 70 nm scale resolution and an aspect ratio of 1, through the secondary-sputtering phenomenon during the Ar-ion-bombardment process. This approach provides a foundation for the design of new routes to BCP lithography.

In this work, we demonstrate that gas adsorption is significantly higher in edge sites of vertically aligned MoS2 compared to that of the conventional basal plane exposed MoS2 films. To compare the effect of the alignment of MoS2 on the gas adsorption properties, we synthesized three distinct MoS2 films with different alignment directions ((1) horizontally aligned MoS2 (basal plane exposed), (2) mixture of horizontally aligned MoS2 and vertically aligned layers (basal and edge exposed), and (3) vertically ...

Slightly tapered Si1−xGex nanowires (NWs) (x = 0.29–0.84) were synthesized via a vapor–liquid–solid procedure using Au as a catalyst. We measured the optically excited carrier dynamics of Si1−xGex NWs as a function of Ge content using optical pump–THz probe spectroscopy. The measured −ΔT/T0 signals of Si1−xGex NWs were converted into conductivity in the THz region. We developed a fitting formula to apply to indirect semiconductors such as Si1−xGex, which explains the temporal population of photo-excited ...

In this study, nanofiltration performance of an ultrathin graphene oxide (GO) membrane was significantly improved by optimizing surface morphology of polycarbonate (PC) support via ion beam treatment. Ion beam can precisely control the dimensions of the wrinkled structure by adjusting exposure time. The wrinkle formation can be attributed to increased degree of polymer cross-linking and heat generation by penetrating Ar+ ions that result in a stiff skin layer. Upon filtration testing, water flux of ...

Because the properties of molybdenum disulfide (MoS2) are strongly influenced by the sizes and boundaries of its domains, the direct visualization of large-area MoS2 domains is one of the most important challenges in MoS2 research. In the current study, we developed a simple and rapid method to observe and determine the boundaries of MoS2 domains. The technique, which depends on observations of nematic liquid crystal textures on the MoS2 surface, does not damage the sample and is not limited by domain ...

Enhancement of the fluorescence intensity of quantum dot (QD)-polymer nanocomposite arrays is an important issue in QD studies because of the significant reduction of fluorescence signals of such arrays due to nonradiative processes in densely packed polymer chains in solid films. In this study, we enhance the fluorescence intensity of such arrays without significantly reducing their optical transparency. Enhanced fluorescence is achieved by hybridizing ultrathin plasmonic Au nanowalls onto the sidewalls ...
