Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

open access: yesAdvanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Moments and Estimation of the Exponentiated Moment Exponential Distribution

open access: yesMathematical Sciences and Applications E-Notes, 2016
A new extension of moment exponential distribution, called exponentiated moment exponential distribution(EMED), was recently introduced by Hasnain [14]. Based on lower generalized order statistics, wefirst derive the explicit expressions as well as recurrence relations for single and product moments of lowergeneralized order statistics and we use these

Scaling‐Up of Structural Superlubricity: Challenges and Opportunities

open access: yesAdvanced Functional Materials, EarlyView.
At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...
