This study explores the structural relationship among digital literacy, learning strategies, and core competencies among South Korean college students as well as the group differences between these variables depending on individual characteristics. Data analysis was conducted by correlation analysis, independent sample t-testing, and structural equation modelling. Participants were 916 college students from 10 colleges in South Korea. The results showed that i) no difference between groups exist

Abstract Polymeric binders that can undergo slurry fabrication and minimize the disruption of interfacial Li + contact are imperative for sheet‐type electrodes and solid electrolyte films in practical all‐solid‐state Li batteries (ASLBs). Although dry polymer electrolytes (DPEs) are a plausible alternative, their use is complicated by the severe reactivity of sulfide solid electrolytes and the need to dissolve Li salts. In this study, a new scalable fabrication protocol for a Li + ‐conductive DP

Abstract Inorganic solid electrolytes (SEs), such as sulfides and halides, are crucial for developing practical all‐solid‐state batteries (ASSBs) owing to their high ionic conductivities and mechanical sinterabilities. However, their sensitivity to humid air necessitates stringent dry‐room conditions during processing, which increases production costs. This study demonstrates that ultrathin (≈5 nm) superhydrophobic polydimethylsiloxane (PDMS) or fluorinated PDMS (F‐PDMS) protective layers can en

Low-emissions can-annular gas turbines are prone to develop low-frequency self-excited thermoacoustic oscillations. Such oscillations arise from the coupling between adjacent combustors and can increase wear and thermal stresses. In this experimental study, we explore the mutual synchronization of two thermoacoustic oscillators (i.e., two model combustors) interacting via dissipative and time-delayed coupling, as introduced via a cross-talk section. Unlike most previous studies, our study makes
