Exploring the potential of lanthanide-doped oxyfluoride materials for bright green upconversion and their promising applications towards temperature sensing and drug delivery.

The most efficient upconversion (UC) materials reported to date are based on fluoride hosts with low phonon energies, which reduce the amount of nonradiative transitions. In particular, NaYF doped with Yb and Er at appropriate ratios is known as one of the most efficient UC phosphors. However, its low thermal stability limits its use for certain applications.

Importance of the pyrolysis for microstructure and superconducting properties of CSD-grown GdBaCuO-HfO nanocomposite films by the ex-situ approach.

For the first time, GdBaCuO nanocomposites were prepared by chemical solution deposition following the ex-situ approach. In particular, ~ 220 nm GdBaCuO-HfO (GdBCO-HfO) nanocomposite films were fabricated starting from a colloidal solution of 5 mol% HfO nanoparticles. Hereby, one of the main challenges is to avoid the accumulation of the nanoparticles at the substrate interface during the pyrolysis, which would later prevent the epitaxial nucleation of the GdBCO grains.

Monometallic Cerium Layered Double Hydroxide Supported Pd-Ni Nanoparticles as High Performance Catalysts for Lignin Hydrogenolysis.

Monometallic cerium layered double hydroxides (Ce-LDH) supports were successfully synthesized by a homogeneous alkalization route driven by hexamethylenetetramine (HMT). The formation of the Ce-LDH was confirmed and its structural and compositional properties studied by XRD, SEM, XPS, iodometric analyses and TGA. HT-XRD, N-sorption and XRF analyses revealed that by increasing the calcination temperature from 200 to 800 °C, the Ce-LDH material transforms to ceria (CeO) in four distinct phases, i.

Assessment of long-term sickness absence: content and face validity of a new questionnaire based on qualitative data from nominal groups.

Background: Increasing rates of long-term sickness absence are a worldwide problem. Belgium is the first country in Europe that aims to screen its entire population of sick leavers (sick leave > 6 weeks) for the risk of long-term sickness absence in order to focus resources on the high-risk group and to provide adequate return-to-work support. Our aim was to investigate content and face validity of a newly designed questionnaire (Quickscan) using item prioritization of patients and professionals in the field of long-term sickness absence.

The effect of a multidisciplinary weight loss program on renal circadian rhythm in obese adolescents.

Adolescent obesity is a serious health problem associated with many comorbidities. Obesity-related alterations in circadian rhythm have been described for nocturnal blood pressure and for metabolic functions. We believe renal circadian rhythm is also disrupted in obesity, though this has not yet been investigated.

Effect of Hydrocortisone Therapy Initiated 7 to 14 Days After Birth on Mortality or Bronchopulmonary Dysplasia Among Very Preterm Infants Receiving Mechanical Ventilation: A Randomized Clinical Trial.

Importance: Dexamethasone initiated after the first week of life reduces the rate of death or bronchopulmonary dysplasia (BPD) but may cause long-term adverse effects in very preterm infants. Hydrocortisone is increasingly used as an alternative, but evidence supporting its efficacy and safety is lacking.

Objective: To assess the effect of hydrocortisone initiated between 7 and 14 days after birth on death or BPD in very preterm infants.

Identification of peripartum near-miss for perinatal audit.

Introduction: Today, perinatal audit focuses basically on cases of perinatal mortality. In most centres in Western Europe, perinatal mortality is low. Identification of metabolic acidosis at birth may increase index cases eligible for evaluation of perinatal care, and this might improve quality of perinatal audit.

The Influence of Deposition Methods of Support Layer on Cordierite Substrate on the Characteristics of a MnO₂-NiO-Co₃O₄/CeZrO₂/Cordierite Three Way Catalyst.

This paper compares different coating methods ( solid combustion, hybrid deposition, secondary growth on seed, suspension, double deposition of wet impregnation and suspension) to deposit CeZrO₂ mixed oxides on cordierite substrates, for use as a three way catalyst. Among them, the double deposition was proven to be the most efficient one. The coated sample shows a BET (Brunauer-Emmett-Teller) surface area of 25 m²/g, combined with a dense and crack free surface.

Prenatal detection of an enteric duplication cyst.

Enteric duplication cysts are rare congenital malformations of unknown aetiology. Because of improvements in prenatal ultrasound, more and more duplication cysts are found prenatally and treatment is started early. We describe a case of enteric duplication cyst diagnosed prenatally and resected soon after birth.

Effects of Varied Cleaning Methods on Ni-5% W Substrate for Dip-Coating of Water-based Buffer Layers: An X-ray Photoelectron Spectroscopy Study.

This work describes various combinations of cleaning methods involved in the preparation of Ni-5% W substrates for the deposition of buffer layers using water-based solvents. The substrate has been studied for its surface properties using X-ray photoelectron spectroscopy (XPS). The contaminants in the substrates have been quantified and the appropriate cleaning method was chosen in terms of contaminants level and showing good surface crystallinity to further consider them for depositing chemical solution-based buffer layers for Y₁Ba₂Cu₃O (YBCO) coated conductors.

X-ray Photoelectron Spectroscopy (XPS) Depth Profiling for Evaluation of La₂Zr₂O₇ Buffer Layer Capacity.

Lanthanum zirconate (LZO) films from water-based precursors were deposited on Ni-5%W tape by chemical solution deposition. The buffer capacity of these layers includes the prevention of Ni oxidation of the substrate and Ni penetration towards the YBCO film which is detrimental for the superconducting properties. X-ray Photoelectron Spectroscopy depth profiling was used to study the barrier efficiency before and after an additional oxygen annealing step, which simulates the thermal treatment for YBCO thin film synthesis.
