PROBING THE VALIDITY OF THE SPINEL INVERSION MODEL: A COMBINED SPXRD, PDF, EXAFS AND NMR STUDY OF ZNAL2O4

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 23 settembre 2020 Spinels are of essential interest in the solid-state sciences with numerous important materials adopting this crystal structure. One defining feature of spinel compounds is their ability to accommodate a high degree of tailorable point defects, and this significantly influences their physical......

IMPACT OF RADIATION EFFECT ON ENERGY STORAGE DENSITY AND WAKE-UP BEHAVIORS OF ANTIFERROELECTRIC-LIKE AL-DOPED HFO2 THIN FILMS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), ven 11 settembre 2020 The γ-ray total dose radiation effects on energy storage density and phase transition of antiferroelectric-like (AFE-like) Al-doped HfO2(HfAlO) thin films were investigated. The energy storage density (ESD) properties and the wake-up behavior during field cycling of the AFE HfAlO thin films......

PHOTOCHEMICAL AND ELECTROCHEMICAL REDUCTION OF GRAPHENE OXIDE THIN FILMS: TUNING THE NATURE OF SURFACE DEFECTS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 09 settembre 2020 Individual and combined photo(electro)chemical reduction treatments of graphene oxide thin films have been performed to modulate the type of defects introduced into the graphene sheets during the reduction. These were characterized by X-ray photoelectron and Raman spectroscopies, nuclear reaction analysis and......

A NEW PLANAR BCN LATERAL HETEROSTRUCTURE WITH OUTSTANDING STRENGTH AND DEFECT-MEDIATED SUPERIOR SEMICONDUCTING TO CONDUCTING PROPERTIES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 09 settembre 2020 Motivated by the recent synthesis of boron-carbon-nitride (BCN) monolayers with different atomic compositions, we propose a novel planar BCN lateral heterostructure with a combination of graphene and hexagonal boron nitride (h-BN) counterparts. Density functional theory (DFT) and classical molecular dynamics (CMD)......

DRIVEN TOPOLOGICAL TRANSITIONS IN ACTIVE NEMATIC FILMS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 08 settembre 2020 The topological properties of many materials are central to their behavior. In intrinsically out-of-equilibrium active materials, the dynamics of topological defects can be particularly important. In this paper, local manipulation of the order, dynamics, and topological properties of microtubule-based active nematic......

TOPOLOGICAL DEFECTS OF DIPOLE PATCHY PARTICLES ON A SPHERICAL SURFACE

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 17 agosto 2020 We investigate the assembly of dipole-like patchy particles confined to a spherical surface by Brownian dynamics simulations. The surface property of the spherical particle is described by the spherical harmonic Y10, and the orientation of the particle is defined as the......
