Depending mostly on voluntarily sent spontaneous reports, pharmacovigilance studies are hampered by low quantity and quality of patient data. Our objective is to improve postmarket safety studies by enabling safety analysts to seamlessly access a wide range of EHR...

Determinants for Sustained Use of an Activity Tracker: Observational Study.

JMIR mHealth and uHealth

Hermsen S, Moons J, Kerkhof P, Wiekens C, De Groot M.
PMID: 29084709
JMIR Mhealth Uhealth. 2017 Oct 30;5(10):e164. doi: 10.2196/mhealth.7311.

BACKGROUND: A lack of physical activity is considered to cause 6% of deaths globally. Feedback from wearables such as activity trackers has the potential to encourage daily physical activity. To date, little research is available on the natural development...

Folate intakes from diet and supplements may place certain Canadians at risk for folic acid toxicity - CORRIGENDUM - ERRATUM.

Nonlinear photoluminescence spectrum of single gold nanostructures.

ACS nano

Knittel V, Fischer MP, de Roo T, Mecking S, Leitenstorfer A, Brida D.
PMID: 25548827
ACS Nano. 2015 Jan 27;9(1):894-900. doi: 10.1021/nn5066233. Epub 2015 Jan 05.

We investigate the multiphoton photoluminescence characteristics of gold nanoantennas fabricated from single crystals and polycrystalline films. By exciting these nanostructures with ultrashort pulses tunable in the near-infrared range, we observe distinct features in the broadband photoluminescence spectrum. By comparing...

Amino Acid-Based Stabilization of Oxide Nanocrystals in Polar Media: From Insight in Ligand Exchange to Solution ¹H NMR Probing of Short-Chained Adsorbates.

Langmuir : the ACS journal of surfaces and colloids

De Roo J, Coucke S, Rijckaert H, De Keukeleere K, Sinnaeve D, Hens Z, Martins JC, Van Driessche I.
PMID: 26854070
Langmuir. 2016 Mar 01;32(8):1962-70. doi: 10.1021/acs.langmuir.5b04611. Epub 2016 Feb 17.

Ligand exchange is a crucial step between nanocrystal synthesis and nanocrystal application. Although colloidal stability and ligand exchange in nonpolar media are readily established, the exchange of native, hydrophobic ligands with polar ligands is less systematic. In this paper,...

Highly Dynamic Ligand Binding and Light Absorption Coefficient of Cesium Lead Bromide Perovskite Nanocrystals.

ACS nano

De Roo J, Ibáñez M, Geiregat P, Nedelcu G, Walravens W, Maes J, Martins JC, Van Driessche I, Kovalenko MV, Hens Z.
PMID: 26786064
ACS Nano. 2016 Feb 23;10(2):2071-81. doi: 10.1021/acsnano.5b06295. Epub 2016 Jan 26.

Lead halide perovskite materials have attracted significant attention in the context of photovoltaics and other optoelectronic applications, and recently, research efforts have been directed to nanostructured lead halide perovskites. Collodial nanocrystals (NCs) of cesium lead halides (CsPbX3, X =...

Theoretical study of photonic band gaps in woodpile crystals.

Physical review. E, Statistical, nonlinear, and soft matter physics

Gralak B, de Dood M, Tayeb G, Enoch S, Maystre D.
PMID: 16241362
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Jun;67(6):066601. doi: 10.1103/PhysRevE.67.066601. Epub 2003 Jun 04.

We investigate numerically the existence of photonic band gaps in woodpile crystals. We present a numerical method specifically developed to solve Maxwell's equations in such photonic structures. It is based upon a rigorous mathematical formulation and leads to a...

A SEM-EDS study of cultural heritage objects with interpretation of constituents and their distribution using PARC data analysis.

Two cultural heritage objects studied with scanning electron microscopy-energy dispersive spectroscopy (EDS) are presented in this article: (1) archeological iron present in a soil sample and (2) a chip from a purple-colored area of an undisclosed 17th century painting....

Improving surgical outcome following the Norwood procedure.

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation

BACKGROUND: The Norwood procedure consists of three palliative operations, performed in neonates with hypoplastic left heart syndrome. Especially the first stage (Norwood I) is associated with the highest mortality rates in paediatric cardiac surgery (up to 25%). During surgery,...

Interference in acetylene intersystem crossing acts as the molecular analog of Young's double-slit experiment.

Proceedings of the National Academy of Sciences of the United States of America

We report on an experimental approach that reveals crucial details of the composition of singlet-triplet mixed eigenstates in acetylene. Intersystem crossing in this prototypical polyatomic molecule embodies the mixing of the lowest excited singlet state (S(1)) with 3 triplet...
