Thoracic aortic atherosclerosis in patients with a bicuspid aortic valve; a case–control study

BMC Cardiovascular Disorders, 2023
Introduction Bicuspid aortic valve (BAV) patients have an increased risk to develop thoracic aortic complications. Little is known about the prevalence and severity of atherosclerosis in the BAV ascending aortic wall.

Circularly Polarized Red‐NIR Emission With High Dissymmetry Factor From Achiral [Mo6I8(OCOC2F5)6]2− Cluster Anion Embedded in a Bent‐Core Liquid Crystal Host

Advanced Optical Materials, EarlyView.
Associating a chiral bent core liquid crystal molecule, that self‐assembles into helical nanofilaments, with an achiral red‐NIR phosphorescent octahedral molybdenum cluster produces a hybrid material exhibiting efficient red‐NIR circularly polarized emission under UV excitation.

Crystallization behaviour of neodymium doped yttrium silicate nanophosphors

, 2011
Sol-gel technique was used to prepare yttrium silicate powders doped with 0.01Nd(3+). The crystallite sizes were determined to be 23 +/- 0.5 nm from the XRD patterns of the powders annealed at 960 degrees C. The Y(4.67)(SiO(4))(3)O, Y(2)Si(2)O(7) and Y(2)

Tailoring Multifunctional Carbon Dots via Precursor Stoichiometry: Switching Between Solid‐State Fluorescence and Broadband Absorption Through Aggregation Control

Advanced Science, EarlyView.
Precursor stoichiometry programs the surface chemistry of carbon dots, directing their self‐assembly into distinct aggregation modes. Aldehyde‐enriched surfaces form ordered, hydrogen‐bonded assemblies that enable bright red solid‐state fluorescence, whereas amine‐rich surfaces promote compact π–π stacked aggregates with broadband visible‐light ...

On the Non-Newtonian Viscous Behavior of Polymer Melts in Terms of Temperature and Pressure-Dependent Hole Fraction

, 2014
A new theoretical non-Newtonian viscosity model is developed by taking the fractional series expansion of Eyring's shearing strain rate. A broad range of experimental rheological data of various polymer melts including polyethylenes, polypropylene ...

Long‐Term Durability of Transcatheter Aortic Valve Prostheses in Patients With Bicuspid Versus Tricuspid Aortic Valve

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Currently, there is a lack of evidence for the long‐term bioprosthetic valve durability of patients with bicuspid aortic valve (BAV) following transcatheter aortic valve replacement (TAVR).

SMAD3 contributes to ascending aortic dilatation independent of transforming growth factor-beta in bicuspid and unicuspid aortic valve disease

Scientific Reports, 2022
We sought to determine whether there are differences in transforming growth factor-beta (TGFß) signaling in aneurysms associated with bicuspid (BAV) and unicuspid (UAV) aortic valves versus normal aortic valves.

Structural and spectroscopic properties of Nd3+:Y2Si2O7 phosphors

, 2013
Phosphors of alpha-Y2Si2O7 doped with Nd3+ ions were prepared using the sol gel technique. Nano-sized crystalline phosphor powders were obtained by annealing the dried gels at 960 degrees C.

Electronic ionisation-induced annealing of pre-existing defects in Al2O3 and CaF2 single crystals

, 2022
Electronic ionisation-induced annealing of pre-existing defects in CaF2 and Al2O3 single crystals has been investigated. Pre-existing defects (vacancies and interstitials) and defect aggregates were first induced in both crystals by fast neutrons ...
