Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

The Kinetic Energy of Relativistic Particles

open access: yes
This paper presents a novel approach to relativistic kinetic energy through the lens of the Hypergeometrical Universe (HU) Theory, introducing an Absolute Reference Frame (ARF) that fundamentally reinterprets the Lorentz transformation. HU suggests that the physics underlying Lorentz transformations is not an intrinsic time dilation or relativistic ...

Spectroelectrochemical Determination of Förster Radii for Triplet‐Polaron Quenching in Phosphorescent Organic Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
Phosphorescent OLEDs suffer from efficiency roll‐off due to triplet‐polaron quenching (TPQ). This study demonstrates for a large set of host‐guest combinations a spectroelectrochemical method to measure the absorption of charged molecules, enabling determining TPQ Förster radii (2.5–4 nm) from the spectral overlap.

Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

open access: yesAdvanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Investigation of the Effect of Restitution Coefficient on 3-Dimensional Rockfall Analyses

open access: yesDoğal Afetler ve Çevre Dergisi
Due to its geological, geomorphological and climatic characteristics, Türkiye frequently experiences natural disasters, among which rockfalls pose significant risks, causing considerable loss of life and property in many regions of the country.
