Origin of two-hole triplet splitting in circular quantum dots
(Elsevier, 2012-05)
Recent photoluminescence spectra of positively charged excitons in InAs/GaAs quantum dots have revealed the existence of large splittings between the View the MathML sourcep-shell triplet sublevels of holes. We provide an ...
Synthesis, optical and ferroelectric properties of PZT thin films: experimental and theoretical investigation
(Royal Society of Chemistry, 2012)
PbZr0.40Ti0.60O3 (PZT40/60) thin films with ferroelectric and dielectric properties have been grown on Pt/Ti/SiO2/Si and LaAlO3 (100) substrates using the chemical solution deposition method. These films have been characterized ...
Magnetic modulation of the tunneling between defects states in antidot superlattices
(IOP Publishing, 2012)
We show theoretically that the tunnelling between properly designed defects in periodic antidot lattices can be strongly modulated by applied magnetic fields. Further, transport channels made up of linear arrangements of ...
Electrostatics as a Guiding Principle in Understanding and Designing Enzymes
(American Chemical Society, 2024-03-12)
Enzyme design faces challenges related to the implementation of the basic principles that govern the catalytic activity in natural enzymes. In this work, we revisit basic electrostatic concepts that have been shown to ...
Structural and vibrational study of cubic Sb2O3 under high pressure
(American Physical Society, 2012)
Curly arrows meet electron density transfers in chemical reaction mechanisms: from electron localization function (ELF) analysis to valence-shell electron-pair repulsion (VSEPR) inspired interpretation
(Royal Society of Chemistry, 2016)
Probing the electron density transfers during a chemical reaction can provide important insights, making possible to understand and control chemical reactions. This aim has required extensions of the relationships between ...
Diamagnetic and paramagnetic shifts in self-assembled InAs lateral quantum dot molecules
(American Physical Society, 2015)
We uncover the underlying physics that explains the energy shifts of discrete states of individual InAs lateral
quantum dot molecules (LQDMs) as a function of magnetic fields applied in the Faraday geometry. We observe
that ...
Synthesis and Structure of Trinuclear W3S4 Clusters Bearing Aminophosphine Ligands and Their Reactivity toward Halides and Pseudohalides
(American Chemical Society, 2014-12-31)
The aminophosphine ligand (2-aminoethyl)diphenylphosphine (edpp) has been coordinated to the W3(μ-S)(μ-S)3 cluster unit to afford trimetallic complex [W3S4Br3(edpp)3]+ (1+) in a one-step synthesis process with high yields. ...
Identification and quantification of flavor compounds in smoked tuna fish based on GC-Orbitrap volatolomics approach
(Elsevier Ltd, 2024-08-15)
Cold smoking enhances the appeal of fish products, offering consumers a smooth texture and a delicate smoky flavor. This study aims to explore variations in the volatile profile from different exposure times during cold ...
Untargeted metabolomics unravels distinct gut microbial metabolites derived from plant-based and animal-origin proteins using in vitro modeling
(Elsevier Ltd, 2024-11-01)
The popularity of plant-based meat alternatives (PBMAs) has sparked a contentious debate about their influence on intestinal homeostasis compared to traditional animal-based meats. This study aims to explore the changes ...
