Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
Advanced Materials, EarlyView.ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Multipolar myths and unipolar fantasies. Egmont Security Policy Brief No. 60, February 2015 [PDF]
, 2015 Is the world becoming multipolar or will it remain unipolar? Analysts disagree, but it might be that this does not matter too much and that we better skip polarity terminology ...

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC
Advanced Materials Interfaces, EarlyView.We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...

Advanced Materials Interfaces, EarlyView.This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

Advances in Halide Perovskites for Photon Radiation Detectors
Advanced Materials Technologies, EarlyView.This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Regulating atomic imbalance in double-well lattices
, 2009 An insulating optical lattice with double-well sites is considered. In the case of the unity filling factor, an effective Hamiltonian in the pseudospin representation is derived.

Advanced Science, EarlyView.Using machine learning on a mega‐scale global dataset (n = 1,336,840) reveals a robust personality trait architecture beyond the Big Five. A Big Two model, broadly capturing social engagement and internal mentation, defines a geometric space that links personality to neurocognitive profiles.
