Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3

open access: yesAdvanced 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 ...

Measurement of $W^{\pm}$ single spin asymmetries and $W$ cross section ratio in polarized $p+p$ collisions at $\sqrt{s}=510$ GeV at STAR [PDF]

open access: yesarXiv, 2017
We present the preliminary results of measurements of single spin asymmetries, $A_L$ for $W^\pm$ boson production in longitudinally polarized p+p collisions at $\sqrt{s}=510$ GeV and measurements of cross section ratios, $\sigma _{W^+} / \sigma _{W^-}$, for $W^+,W^-$ boson production in $p+p$ collisions at $\sqrt{s}$ = 500 and 510 GeV.

Direct Evidence of the Presence of Hybrid Charge Transfer State in a Perovskite Nanocrystal‐Polythiophene Blend Solid State Film

open access: yesAdvanced Materials Interfaces, EarlyView.
The photophysical properties of a hybrid solid state film, composed of a conjugated polymer and CsPbBr3 (zwitterionic sulfobetaine ‐capped) perovskite nanocrystals (NCs), are investigated by ultrafast spectroscopy and morphological characterization. The transient spectroscopy highlights the presence at the interface of a charge transfer state, and the ...

Reference dietary patterns in Portugal: Mediterranean diet vs Atlantic diet

open access: yesOpen Agriculture
Portugal is influenced by the Atlantic Ocean to the west and the Mediterranean Sea to the south. Thus, the dietary patterns in Portugal include both the Mediterranean diet (MD) and the Atlantic diet (AD).

Inclusive Jet Longitudinal Double-spin Asymmetry $A_{LL}$ Measurements in 510 GeV Polarized $pp$ Collisions at STAR [PDF]

open access: yesarXiv, 2019
In this analysis, I perform the first ever measurement of \(A_{LL}\) for inclusive jet production in \(pp\) collisions at the higher beam energy of \(\sqrt{s}\) = 510 GeV, based on data that STAR recorded during 2012. The higher beam energy extends the sensitivity to gluon polarization down to \(x \sim 0.02\).

Atomic‐Scale Mechanisms of Nucleation and Stabilization in CuCrO2 and CuFeO2 Delafossite Thin Films on Al2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, a combination of 4D STEM phase reconstructions via iterative electron ptychography, spectroscopy, and conventional STEM imaging reveals detailed insights into the nucleation mechanism for the stable growth of Cu‐based delafossites on Al2O3 using CuCrO2 and CuFeO2 films grown via MBE as examples.
