Cu2ZnSnS4 films with Cu-poor composition prepared by spin coating from a nontoxic methanol-based solution: the effect of annealing temperature

open access: yesJournal of Asian Ceramic Societies, 2020
In comparison with the stoichiometry and Zn-rich/Cu-poor compositions of Cu2ZnSnS4 (CZTS) photovoltaic material, the properties of Cu-poor films have not been explored adequately.

The Electrical Properties of Tb-Doped CaF2 Nanoparticles under High Pressure

open access: yesCrystals, 2018
The high-pressure transport behavior of CaF2 nanoparticles with 3 mol% Tb concentrations was studied by alternate-current impedance measurement. All of the electrical parameters vary abnormally at approximately 10.76 GPa, corresponding to the fluorite ...

Transport Properties of Rippled Graphene [PDF]

open access: yesActa Physica Polonica A, 2012
The exceptionally high mobility of carriers in graphene is one of its defining characteristics, especially in view of potential applications. Therefore it is of both practical and fundamental importance to understand the mechanisms responsible for limiting the values of mobility.

Robust Transport Properties in Graphene [PDF]

open access: yesPhysical Review Letters, 2006
Two-dimensional Dirac fermions are used to discuss quasiparticles in graphene in the presence of impurity scattering. Transport properties are completely dominated by diffusion. This may explain why recent experiments did not find weak localization in graphene.

Transport Properties of Intergrowth Structures Ba5In2Al2ZrO13 and Ba7In6Al2O19

open access: yesApplied Sciences, 2023
The development of solid oxide fuel cells operating at medium temperatures (500–700 °C and even lower) requires the search for proton conductors based on complex oxides that would have a wide range of required properties.

Effective Transport Properties

open access: yes, 2022
Porous media are an integral part of electrochemical energy conversion and storage devices, including fuel cells, electrolyzers, redox flow batteries and lithium-ion batteries, among others. The calculation of effective transport properties is required for designing more efficient components and for closing the formulation of macroscopic continuum ...

Genomic Diversity and Clinical Variability in Pediatric Primary Cutaneous Anaplastic Large Cell Lymphoma: A Case Series

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...
