Anisotropic Phonon Dynamics and Directional Transport in Actinide Van der Waals Semiconductor Uranium Triselenide

Advanced Functional Materials, EarlyView.
USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

Circularly polarised higher-order rectangular dielectric-resonatorantenna

Electronics Letters, 1996
A circularly polarised, rectangular, low-profile, dielectric-resonator antenna is presented which is fed by a 50/spl Omega/ microstrip line through a single aperture. The measured 3dB axial-ratio bandwidth in the boresight direction is 14.35-14.80 GHz (3%).

Two Sides to Every Story: Measuring the Polarisation of Work [PDF]

Individual and household based aggregate measures of joblessness can, and do, offer conflicting signals about labour market performance if work is unequally distributed.

Dielectric tensor of photoinduced polarisation converters in optical fibres

, 1993
We show that unusual forms of dielectric tensor, leading to novel polarisation convertors, can be induced in fibers by interferometric exposure to orthogonally polarized UV ...

Two-dimensional BRDF estimation from polarisation

, 2008
This paper presents a novel technique for reflectance function (BRDF) estimation, which uses polarisation information and photometric stereo. The first stage of the technique is standard and involves the acquisition of polarisation information (angle and

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

The Extra‐Low Frequency Dielectric Analysis Method for Evaluating Byproducts of Cross‐Linked Polyethylene Cable Insulation Materials

High Voltage
Cross‐linking byproducts in the cross‐linked polyethylene (XLPE) cable insulation material significantly affect the insulation properties of XLPE, and the non‐destructive detection method for cross‐linking byproducts during cable degassing process still ...

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.

Polarisation and Health [PDF]

This paper examines the effect of income polarisation on individual health. We argue that polarisation captures much better the social tension and conflict that underlie some of the pathways linking income disparities and individual health, and which ...
