Live Imaging of Silver Nanostructures Electrochemically Dissolving at Open‐Circuit Potential

open access: yesSmall, EarlyView.
Stability of electrocatalysts as used in energy conversion systems is pivotal for sustainable technologies, yet degradation dynamics at the nanoscale remain elusive. Harnessing beam‐effect corrected electrochemical liquid phase electron microscopy combined with correlative bulk‐scale electrochemical testing reveals silver corrosion on platinum under ...

The Impacts of Removing College Entrance Exams: Evidence From the Test‐Optional Movement

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT Before 2020, around 250 four‐year colleges and universities adopted a test‐optional application procedure that allowed students to apply for admission without submitting college entrance exam score. Many schools adopted this procedure to encourage greater racial and socioeconomic diversity.

Technology‐Enabled Cross‐Border Entrepreneurship: The Role of Digital Platforms in SME Expansion Through the Lens of Institutional Theory

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT Small and medium‐sized enterprises (SMEs) face significant institutional barriers when expanding across borders, including regulatory constraints, financial accessibility issues, and market entry challenges. Institutional theory provides a useful framework for understanding how external regulative, normative, and cognitive institutional forces
