Structure, electronic properties, morphology evolution, and photocatalytic activity in PbMoO4 and Pb12xCaxSrxMoO4 (x = 0.1, 0.2, 0.3, 0.4 and 0.5) solid solutions
(Royal Society of Chemistry, 2020)
In this work PbMoO4 and Pb12xCaxSrxMoO4 (x = 0.1, 0.2, 0.3, 0.4 and 0.5) solid solutions have been
successfully prepared, for the first time, by a simple co-precipitation method and the as-synthesized
samples were subjected ...
Travelling wave ion mobility-derived collision cross section for mycotoxins: Investigating interlaboratory and interplatform reproducibility
(American Chemical Society, 2020-09-01)
Parent and modified mycotoxin analysis remains a challenge because of their chemical diversity, the presence of
isomeric forms, and the lack of analytical standards. The creation and application of a collision cross section ...
A simple variational quantum Monte Carlo-effective mass approach for excitons and trions in quantum dots
(Elsevier, 2021)
A computational model is presented to calculate the ground state energy
of neutral and charged excitons confined in semiconductor quantum dots.
The model is based on the variational Quantum Monte Carlo method and
effective ...
Selective Synthesis of α-, β-, and γ-Ag2WO4 Polymorphs: Promising Platforms for Photocatalytic and Antibacterial Materials
(American Chemical Society, 2021-01-18)
Silver tungstate (Ag2WO4) shows structural polymorphism with different crystalline phases, namely, orthorhombic, hexagonal, and cubic structures that are commonly known as α, β, and γ, respectively. In this work, these ...
Coulomb interaction signatures in self-assembled lateral quantum dot molecules
(American Physical Society, 2013)
We use photoluminescence spectroscopy to investigate the ground state of single self-assembled InGaAs lateral
quantum dot molecules. We apply a voltage along the growth direction that allows us to control the total ...
Monitoring psychoactive substance use at six European festivals through wastewater and pooled urine analysis
(Elsevier, 2020-07-10)
The consumption of psychoactive substances is considered a growing problem in many communities. Moreover, new psychoactive substances (NPS) designed as (legal) substitutes to traditional illicit drugs are relatively easily ...
Two-Photon Induced Blue Shift of Core and Shell Optical Transitions in Colloidal CdSe/CdS quasi-type II Quantum Rods
(American Chemical Society, 2013-03)
The spectral dependence of the two-photon absorption in CdSe/CdS core/shell nanocrystal heterorods has been studied via two-photon-induced luminescence excitation spectroscopy. We verified that the two-photon absorption ...
Toward an Understanding of the Hydrogenation Reaction of MO2 Gas-Phase Clusters (M = Ti, Zr, and Hf)
(American Chemical Society, 2013)
A theoretical investigation using density functional theory (DFT) has been carried out in order to understand the molecular mechanism of dihydrogen activation by means of transition metal dioxides MO2 (M = Ti, Zr, and Hf) ...
Chromatography hyphenated to high resolution mass spectrometry in untargeted metabolomics for investigation of food (bio)markers
(Elsevier, 2021-02-01)
Currently, there is a growing demand by our society, authorities and science to increase the
knowledge about the quality of food and its relationship with health and disease. Untargeted
metabolomics approaches are emerging ...
Integrated experimental and theoretical study on the phase transition and photoluminescent properties of ZrO2:xTb3+ (x=1, 2, 4 and 8 mol %)
(Elsevier ScienceDirect, 2021-08-25)
Zirconia (ZrO2) has been intensively studied as an important ceramic material, and numerous technological applications have been found. The present work deals with synthesizing and characterizing the phase transition (cubic ...
