Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

Advanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Proximity Ferroelectricity in Compositionally Graded Structures

Advanced Electronic Materials, EarlyView.
We perform the finite element modeling of the polarization switching in the compositionally graded AlN‐Al1‐xScxN and ZnO‐Zn1‐xMgxO structures and reveal the switching of spontaneous polarization in the whole structure in all these systems. The coercive field to switch is significantly lower than the electric breakdown field of the unswitchable AlN and ...

For the Few, Not the Many: Tracing the Residualist and Compensatory Nature of British Energy Support

Environmental Policy and Governance, EarlyView.
ABSTRACT Drawing on extensive documentary analysis, this article traces the evolution of British energy policy support since World War II. It analyses shifts in policy design through two interpretive lenses: eligibility (residualist vs. universalist) and function (compensatory vs. preventive).

Two Shades of Green? Gender Differences in Environmental Concern and Activism

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines gender differences in environmental concern and activism using data from the World Values Survey. The results indicate that women are more likely than men to be concerned about the environment, but are less likely to engage in environmental activism.

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Stratigraphic schemes of the Precambrian of the Ukrainian Shield (analytical review)

Мінеральні ресурси України
The first stratigraphic schemes of the Precambrian of the Ukrainian Shield were compiled in 1926 by V. I. Luchytskyi and D. M. Sobolev, and were subsequently developed by numerous authors until 1967.
