In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

„… aby národové naši ještě toho dočěkali, abychom Čechové, Moravané a Slezáci byli…”. Elity polityczne Królestwa Czeskiego wobec Śląska i Ślązaków w pierwszej połowie XVI wieku | [May our nations see it pass that we be Czechs, Moravians and Silesians]. Political elites of the Kingdom of Bohemia in relation to Silesia and the Silesians in the first half of the 16th century [PDF]

open access: yesHistorie - Otázky - Problémy, 2019
The paper deals with some inherited traits in the relationship between the bureaucratic elite of the Kingdom of Bohemia and Silesia. One of the tendencies was an emphasis on preserving the integrity of the Crown of the Kingdom of Bohemia, especially at ...

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

High‐Entropy Perovskite Nanofibers for Bifunctional Air Electrodes in Reversible Protonic Ceramic Electrochemical Cells

open access: yesAdvanced Functional Materials, EarlyView.
High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.
