Geometrical and Electronic Structure of Fluorinated and Non‐Fluorinated Platinum(II) Tetraphenylporphyrin Complexes

open access: yesChemPhysChem, EarlyView.
The experimental gas‐phase geometries of two platinum complexes, free from intermolecular interactions, can serve as references for related complexes in the crystalline state or solution. A significant electron density transfer from the porphyrin backbone to the platinum ion make it extremely low positive charged at +0.5 e.

Understanding phenomena: From social to collective?

open access: yesPhilosophical Issues, Volume 32, Issue 1, Page 253-267, October 2022., 2022
Abstract In making sense of the world, we typically cooperate, join forces, and draw on one another's competence and expertise. A group or community in which there is a well‐functioning division of cognitive‐epistemic labor can achieve levels of understanding that a single agent who relies exclusively on her own capacities would probably never achieve.

Global quantum correlations in finite-size spin chains

open access: yesNew Journal of Physics, 2013
We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently proposed measure for global quantum correlations (Rulli and Sarandy 2011 Phys.

Nonadditive CO2 Uptake of Type II Porous Liquids Based on Imine Cages

open access: yesChemPhysChem, EarlyView.
Type II porous liquids based on porous imine cages (CC13/CC19) show non‐additive CO2 uptake, surpassing ideal volume additivity predictions. Experiments and simulations reveal enhanced gas absorption, with CO2 partitioning into cage pores and solvent.

Responsibility in epistemic collaborations: Is it me, is it the group or are we all to blame?

open access: yesPhilosophical Issues, Volume 32, Issue 1, Page 335-350, October 2022., 2022
Abstract According to distributed virtue reliabilism (Palermos, 2020b), epistemic collaborations—such as Transactive Memory Systems and Scientific Research Teams—can be held epistemically responsible at the collective level. This raises the question of whether participants of epistemic collaborations are exempt from being held individually responsible.

A Direct Measurement of the Absolute Energies of Protonated Gly‐Pro‐Gly‐Gly Conformations Using Ion Mobility Spectrometry and Guided Ion Beam Tandem Mass Spectrometry

open access: yesChemPhysChem, EarlyView.
Relative energies of the cis and trans conformers of the protonated tetrapeptide, Gly‐Pro‐Gly‐Gly, selected by ion mobility spectrometry are measured using threshold collision‐induced dissociation. The trans conformation was found to be more stable than the cis conformation by 4.5 ± 2.5 kJ mol−1 at 0 K, a value in agreement with several levels of ...

Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.

Weak measurements and nonClassical correlations [PDF]

open access: yesarXiv, 2015
We extend the definition of quantum discord as a quantifier of nonClassical correlations in a quantum state to the case where weak measurements are performed on subsystem $A$ of a bipartite system $AB$. The properties of weak discord are explored for several families of quantum states.

Resources and Personal Adjustment for Career Transitions Among Adolescents: A Latent Profile Analysis

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Career transitions are considered to be the most challenging tasks in adolescence. Personal resources are important factors in coping with the difficulties encountered during transitions and help individuals to adjust more smoothly to these transitions.

Quantum Processes Which Do Not Use Coherence

open access: yesPhysical Review X, 2016
A major signature of quantum mechanics beyond classical physics is coherence, the existence of superposition states. The recently developed resource theory of quantum coherence allows the formalization of incoherent operations—those operations which ...
