Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3

Advanced Materials Interfaces, EarlyView.
The subsurface Ba2+disorder, reveals the pairs of O vacancies (VO++$V_O^{ + + }$ s) and small polarons (SPe‐SPe−$SP_e^ - $ s) (Figure a–b), with the charge balance, as the following: Ti3++[VO+++SPe−]pair↔Ti4+${{T}_i}^{3 + } + {{[V_O^{ + + } + SP_e^ - ]}_{pair}} \leftrightarrow T_i^{4 + }$ which is consistent with observed low‐energy electron ...

Coupling hydrothermal liquefaction and aqueous phase reforming for integrated production of biocrude and renewable H2

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract Lignin‐rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen was produced by aqueous phase reforming (APR) of the HTL aqueous by‐product. The effects of Na2CO3 and NaOH were investigated both in terms of processability of the feedstock as well as yield and ...

Lipid‐Hybrid Multicompartment Membrane Systems for Controlled, Compartmentalized Encapsulant Release

Advanced Materials Interfaces, EarlyView.
Herein a bio‐inspired, lipid‐hybrid‐based multicompartmental material for scalable (milliliter) microencapsulation (20 – 200 µm) and controlled release of aqueous solutions is presented. The multicompartmental architecture provides non‐mixing environments, spatial patterning of encapsulants, and controlled compartmentalized release by surfactant ...

Sanction or Financial Crisis? An Artificial Neural Network-Based Approach to model the impact of oil price volatility on Stock and industry indices [PDF]

arXiv, 2019
In this paper, we model the impact of oil price volatility on Tehranstock and industry indices in two periods of international sanctions and post-sanction. To analyse the purpose of study, we use Feed-forward neural net-works. The period of study is from 2008 to 2018 that is split in two periods during international energy sanction and post-sanction ...
