Morphological and Interfacial Engineering of Cobalt-Based Electrocatalysts by Carbon Dots for Enhanced Water Splitting
Get PDFCobalt-based electrocatalysts have garnered significant interest for their potential in water splitting applications. However, their limited functionality, subpar performance, and sensitivity to electrolyte pH levels have hindered their further advancement. In this study, we explored morphological and interfacial modifications of cobalt nanoparticles by incorporating carbon dots (CDs). Specifically, we synthesized nitrogen-doped carbon-encapsulated cobalt nanoparticles (N−C@Co NPs) in situ, aiming for superior performance in electrocatalytic water splitting. These N−C@Co NPs exhibited remarkable hydrogen evolution performance in both acidic and alkaline environments, with overpotentials of 137 mV and 134 mV at 10 mA/cm2, respectively. Additionally, they demonstrated excellent oxygen evolution performance in alkaline media, with an overpotential of 353 mV at 10 mA·cm-2. These achievements surpass those of many previously reported cobalt-based electrocatalysts and are comparable to several outstanding nonprecious metal-based electrocatalysts. We observed that CDs play a significant role in shaping the catalyst morphology and bonding structure between N−C and Co NPs, revealing synergistic effects for water splitting. Furthermore, we validated this approach by enhancing oxygen evolution reaction (OER) activities using CDs-decorated cobaltic oxide nanoparticles (CDs@Co3O4NPs), showing an overpotential of 304 mV at 10 mA/cm2. This study presents a promising approach for synthesizing stable metal-based carbon hybrids with high-performance photo/electrocatalytic activities
Outdoor Adventure Camp Impact on Emotional Regulation in Youth
Get PDFOutdoor Adventure Camps (OACs) have proven beneficial for the mental and physical health of youth across age groups (Bowers et al., 2019; Eigenshenk et al., 2019). OACs have typically been reserved for the middle and upper class of the United States and have only recently been made available to low-income groups (Browne et al., 2019). Within the low-income population we also typically see a higher incidence of behavioral issues stemming from emotional regulation difficulties in children (Collins et al., 2017). The purpose of this study is to better understand the beneficial outcomes of OACs with regard to emotional regulation in low-income youth. Participants completed the ERQ-CA at the beginning and end of their week at camp to assess the change in reappraisal and suppression, the two critical components of emotional regulation. This data, alongside counselor journals, and semi-structured discussions led and hosted by counselors on the last day of camp, provided several different perspectives regarding the benefits of OACs with low-income populations. Findings may provide significant support for the funding of more access to OACs for low-income populations
Influence of Facebook Advertisement on University Enrollment by International Students
Get PDFThis research study utilizes a complete methodology that is based on research methodologies and technology to explore the impact that Facebook advertisements have on university enrollment. In an era of digital connections and dynamic marketing methods, institutions are increasingly relying on social media platforms, especially Facebook, to attract potential students. This study looks into the multiple aspects of Facebook ads, examining their efficacy in increasing enrollment and the underlying technical mechanisms at work. The purpose of the research is to provide practical insights that may help improve the strategic use of digital platforms to promote university enrollment, as well as to contribute to the continuing discussion about the changing landscape of educational marketing in the digital era
