Quantifying Strain and Its Effect on Charge Transport in Ge/Si Core/Shell Nanowires

open access: yesAdvanced Science, Volume 13, Issue 32, 9 June 2026.
This work demonstrates strain engineering in Ge/Si core–shell nanowires (CS NWs) by tuning the Ge core‐Si shell dimensions. Polarization‐resolved µ‐Raman and geometrical phase analysis quantify the resulting strain. Electronic transport measurements demonstrate record hole mobilities up to 25 400 cm2/Vs, highlighting these Ge/Si CS NWs as a promising ...

Thermal Conductivity Across the Nonpolar‐Polar Phase Transition in Incipient Ferroelectric KTaO3

open access: yesAdvanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Phonon dispersion of the cubic nonpolar ground‐state and a ferroelectric tetragonal phase, stabilized by a compressive strain of 2%. ABSTRACT The manipulation of the lattice of polar materials via external electric fields is an effective way to dynamically control the heat flux, accessing different thermal conductivity, κ${\bm \kappa }$, states ...

Delayed Halide‐Rich Molecular Passivation of CsPbCl3 Perovskite Nanocrystals Enables Bright Violet Light‐Emitting Diodes

open access: yesAngewandte Chemie, Volume 138, Issue 23, 1 June 2026.
POCl3 enables delayed dual passivation in CsPbCl3 nanocrystals by slowly releasing Cl‐containing and phosphonic species that heal halide vacancies and Pb‐related defects over time. This self‐healing boosts PLQY by >40‐fold, preserves efficient violet emission for over 2 months in air, and yields a record 409 cd m−2 luminance for CsPbCl3 violet LEDs ...

Tests for Categorical Data Beyond Pearson: A Distance Covariance and Energy Distance Approach

open access: yesBiometrical Journal, Volume 68, Issue 3, June 2026.
ABSTRACT Categorical variables are of uttermost importance in biomedical research. When two of them are considered, it is often the case that one wants to test whether or not they are statistically dependent. We show weaknesses of classical methods—such as Pearson's and the G$G$‐test—and we propose testing strategies based on distances that lack those ...

Sustainable Development and Social Inclusion: Efficiency Evidence From Spain and Policy Pathways for the SDGs

open access: yesBusiness Strategy &Development, Volume 9, Issue 2, June 2026.
ABSTRACT This study examines how hospitality efficiency, sustainability and social inclusion are associated with the achievement of the Sustainable Development Goals (SDGs) in Spain's 17 autonomous communities (ACs) in 2023. Using non‐parametric efficiency analysis with bootstrap correction, quantile regression models, and Random Forest methods, an ...
