Selective Interfacial Barriers Drive High‐Performance GeTe Thermoelectrics
Advanced Science, EarlyView.Carrier‐phonon decoupling is the key to developing high‐performance thermoelectric materials. Here, we demonstrate that selective interfacial barriers can decouple carrier and phonon transport, thus achieving an exceptional peak ZT of ∼2.7 at 773 K, along with a record‐high average ZT of 1.9 across 300–773 K in the (Ge0.82Mn0.04Bi0.04Pb0.1Te)0.99(VSe2 ...

Introduction to measures of inequality and concentration in tourism [PDF]
, 2016 There are many statistical measures available in the literature for the analysis of inequality and concentration. The most common measure in this field is the Gini index (Roselló Nadal et al.,2004), which is associated to the Lorenz curve.

Memristive Physical Reservoir Computing
Advanced Science, EarlyView.Memristors’ nonlinear dynamics and input‐dependent memory effects make them ideal candidates for high‐performance physical reservoir computing (RC). Based on their conductance modulation, memristors can be classified as electronic or optoelectronic types.

Rare‐Earth Yttrium Doping Advances High‐Performance AgSbTe2 Thermoelectrics
Advanced Energy Materials, EarlyView.Y‐doped AgSbTe2 achieves band and microstructure co‐optimization, with coherent Y‐Ag2Te interfaces enhancing phonon scattering and reducing lattice thermal conductivity to 0.26 W m−1 K−1. Combined with valence‐band broadening and increased carrier concentration, this yields ZT ≈ 2 at 623 K, average ZT = 1.5, and 7.3 % conversion efficiency of a single ...

Parametric Lorenz Curves and the Modality of the Income Density Function [PDF]
, 2012 Similar looking Lorenz Curves can imply very different income density functions and potentially lead to wrong policy implications regarding inequality. This paper derives a relation between a Lorenz Curve and the modality of its underlying income density:

Achieving Phonon‐Glass Electron‐Crystal Behavior in Fully Organic Flexible Thermoelectrics
Advanced Energy Materials, EarlyView.Phonon‐glass Electron‐crystal (PGEC) behavior is demonstrated in fully organic composites consisting of conductive polymers (PEDOT:PSS) and soft polymeric fillers (PVA). The optimized PEDOT:PSS–PVA composite concurrently reveals delocalized transport and thermal conductivity close to its theoretical minimum, yielding a superior thermoelectric figure of

Concepts of Reliability Theory and Their Relationship with the Economic Inequality indicators
پژوهشهای ریاضی, 2020 Introduction One of the intersecting aspects of the reliability theory and economics is investigating non-negative data generally skewed (lifetimes and income), extrapolation of a suitable model for the data and finding their characteristics ...
