Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Performance Analysis of SPSK with Dual Polarized Transmit Antennas over Rayleigh Fading Channel

Journal of Telecommunications and Information Technology, 2018
In this paper, the Space Polarization Shift Keying (SPSK) system, which is an extended version of Space Shift Keying (SSK) and includes both space and polarization dimensions with dual polarized antennas, is studied.

On Some Extended Dual Polar Spaces, I

European Journal of Combinatorics, 1994
An extended dual polar space is a polar space which is extended by a Buekenhout-\(c\)-geometry ``at the side of the generalized quadrangle'', i.e. the \(c\)-stroke is next to the double stroke in the diagram. When classifying finite flag-transitive extended dual polar spaces, one can use the classification of the finite classical flag-transitive ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Low Profile Dual Linearly Polarized 1-bit Transmitarray Exploiting Two Metallic Layers

IEEE Access
A novel azimuth-independent dual linearly polarized (LP) transmitarray (TA) based on a polarization rotator is presented. The exploitation of either right-handed circularly polarized (RHCP) or left-handed CP (LHCP) scattered field is at the basis of the ...

Study of the Colocated Dual-Polarized MIMO Capacity Composed of Dipole and Loop Antennas

International Journal of Antennas and Propagation, 2015
The colocated dual-polarized dipole (DPD) and dual-polarized loop (DPL) MIMO channel performances are compared. Computation results show that, for the ideal electric and magnetic dipoles, the dual-polarized MIMO systems have identical channel capacity ...

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

Advanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

Advanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.
