Edukologijos Sistema

open access: yesActa Paedagogica Vilnensia, 1999
Nors pastaruoju metu pasirodė nuodugnių edukologijos objekto ir sistemos tyrimų, verta dar kartą pažvelgti į tai, ką iš esmės tiria edukologai, ar tyrimo rezultatai gali būti vadinami mokslu, kokia to mokslo sistema. Taigi mums rūpi edukologijos dalykas, jos sistema. Čia bus siekiama rasti atsakymą tiems, kas abejoja edukologijos moksline verte.

Electrolyte–Framework Matching in High‐Voltage TEMPO‐COF Cathodes for Lithium Batteries

open access: yesAdvanced Science, EarlyView.
TEMPO‐functionalized covalent organic frameworks are investigated as high‐voltage cathodes for lithium batteries. Screening five electrolyte anions identifies lithium difluoro(oxalato)borate (LiDFOB) as the optimal electrolyte, balancing capacity, rate capability, and cycling stability, while buckypaper electrodes achieve high mass loading (40 mg cm−2)
