Crystalline or amorphous? A critical evaluation of phenomenological phase selection rules

Materials & Design, 2023
In this work, we reviewed the available phase selection rules comprising atomic size and topological aspects, entropies, enthalpies, melting points, valence and itinerant electron concentrations, as well as electronegativity, and validated them using a ...

Propagation topography of redox phase transformations in heterogeneous layered oxide cathode materials

Nature Communications, 2018
Redox phase transformations are relevant to a number of metrics pertaining to the electrochemical performance of batteries. These phase transformations deviate from and are more complicated than the conventional theory of phase nucleation and propagation,

Nanophase identification via correlative transmission electron microscopy: A case study of galvannealed advanced high-strength steel

Materials & Design
The unambiguous identification of nanoscaled phases is an extensively challenging task, which stretches conventional analytical methods to the limit. It holds especially true for nanophases embedded in a matrix with a similar structure and/or chemistry ...

Canonical transformations of the extended phase space, Toda lattices and Stackel family of integrable systems

, 1999
We consider compositions of the transformations of the time variable and canonical transformations of the other coordinates, which map completely integrable system into other completely integrable system.

First Order Actions and Duality [PDF]

, 2006
We consider some aspects of classical S-duality transformations in first order actions taken into account the general covariance of the Dirac algorithm and the transformation properties of the Dirac bracket. By classical S-Duality transformations we mean

Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

Insight into grain boundaries with reduced liquid metal embrittlement susceptibility in a boron-added 3rd generation advanced high strength steel

Materials & Design
The addition of boron to the advanced high-strength steels (AHSS) enhances grain boundary cohesion and can play a significant role in intergranular degradation phenomena such as Zn-assisted liquid metal embrittlement (LME). The objective of this study is

Multichannel generalization of eigen-phase preserving supersymmetric transformations

, 2013
We generalize eigen-phase preserving (EPP) supersymmetric (SUSY) transformations to $N>2$ channel Schr\"odinger equation with equal thresholds. It is established that EPP SUSY transformations exist only in the case of even number of channels, $N=2M$.
