The effect of Gd doping and O deficiency on the electronic structure, exchange interaction, and Curie temperature of EuO in the cubic and tetragonal phases is studied by means of density functional theory. For both defects, the Curie temperature is found to exhibit a distinct maximum as a function of the defect concen…
BACKGROUND: Minimizing the impact of oxidation on ultrahigh-molecular-weight polyethylene components is important for preserving their mechanical integrity while in vivo. Among the strategies to reduce oxidation in modern first-generation highly crosslinked polyethylenes (HXLPEs), postirradiation remelting was conside…
A compact waveguide crossing constructed by a cascaded multimode tapered structure is numerically presented. By using an eigenmode expansion method, we observe that the phase difference between the two lowest guided modes can be changed after a multimode waveguide junction because of the coupling between these two gui…
The objective of this work is to analyze the hot blow-out test procedure (HOBT) used to determine the maximum operating temperature of Teflon-based gaskets. The study focuses on the effect of thermal cycles and a few considerations that can be made to improve the characterization procedure for better prediction of the…
Proteins implement most of the vital molecular functions of living organisms, including structural support, energy generation, biomolecule sensing, and chemical catalysis, storage, and degradation. While capturing proteins in materials could create devices that mimic these functions, this process is challenging due to…
The adsorption of toluene (TOL) as a target volatile organic compound has been studied experimentally and modelled on various hydrophobic zeolites: Faujasite (FAU), ZSM-5 (Z) and Mordenite (MOR). The influence of the nature of the compensating cation (H+ or Na+) has also been investigated for ZSM-5 zeolite, which is k…
Abstract Ultrasonic cavitation experiments using a piezoceramic-based apparatus, according to ASTM G32-2010, were performed on heat and thermochemically treated Cr – Mn low alloyed steel samples. The microstructure in annealed, carburized and tempered states as well as following a duplex treatment (carburized, surface…
Catalytically active proteins with divergent dual functions are often described as 'moonlighting'. In this work we characterize a new, chromatin-based function of Lys20, a moonlighting protein that is well known for its role in metabolism. Lys20 was initially described as homocitrate synthase (HCS), the first enzyme i…
We report the strong experimental evidence of the existence of topological surface states with large electric field tunability and mobility in β-Ag2Te. Pronounced 2D Shubnikov-de Haas oscillations have been observed in β-Ag2Te nanoplates. A Berry phase is determined to be near π using the Landau level fan diagram for…
UNLABELLED: We report a rare case of a cardiac hydatid cyst that was incidentally found during routine work up for a redo-CABG and was picked up on echocardiography and confirmed by magnetic resonance imaging and, after successful removal, further confirmed by histopathology. The report emphasizes the importance of ea…
We have proposed a new semi-insulating GaN buffer layer, which consists of multiple carbon-doped and undoped GaN layer. The buffer layer showed sufficiently good semi-insulating characteristics, attributed to the depletion effect between the carbon-doped GaN and the undoped GaN layers, even though the thickness of the…
The 20 residue long Trp-cage miniprotein is an excellent model for both computational and experimental studies of protein folding and stability. Recently, great attention emerged to study disease-related protein misfolding, aggregation, and amyloid formation, with the aim of revealing their structural and thermodynami…
Under identical conditions, CuI reacts with PhS(CH2 )8 SPh and p-TolS(CH2 )8 STol-p affording, respectively, a luminescent 1D coordination polymer [Cu4 I4 {μ2 -PhS(CH2 )8 SPh}2 ]n (1) and an unprecedented 2D network [Cu8 I8 {μ2 -p-TolS(CH2 )8 STol-p}3 (MeCN)2 ]n (2), which incorporate closed-cubane Cu4 I4 and octanucl…
Morphological control of transition-metal oxides has received great attention for the preferential exposure of catalytically active sites. However, in contrast to catalytic processes, structural damage and relaxation of metal-oxide-based oxygen carriers (OCs) occur during the chemical looping combustion (CLC) processe…
Abstract The effect of incorporation of plasmonic gold (Au) nanoparticle at the interface between transparent front electrode and hole transporting layer of molybdenum trioxide is studied using bulk heterojunction organic photovoltaic cells (OPVs) of poly-3- hexylthiophene and phenyl-C
We study the structural, electronic, and spectroscopic properties of pentacene adsorbed on Al(001) surface, combining density functional theory (DFT) methods including van der Waals interactions with X-ray photoemission (XPS), near-edge X-ray absorption fine structure (NEXAFS), and scanning tunneling microscopy (STM).…
BACKGROUND: The purpose was to determine the influence of irrigation solution osmolarity on articular chondrocytes survival and metabolic state following mechanical injury. METHODS: Osteochondral explants were harvested from patients undergoing total knee arthroplasty for osteoarthritis and then cut through their full…
The tricarboxylic acid (TCA) cycle is a central metabolic pathway that is present in all aerobic organisms and initiates the respiration of organic material. The glyoxylate cycle is a variation of the TCA cycle, where organic material is recycled for subsequent assimilation into cell material instead of being released…
Salivary gland hypofunction often results from a number of causes, including the use of various medications, radiation for head and neck tumors, autoimmune diseases, diabetes, and aging. Since treatments for this condition are lacking and adult salivary glands have little regenerative capacity, there is a need for cel…
Abstract Tissue engineering was introduced by Vacanti and Langer in the 80's, exploring the potential of this new technology starting with the well-known "human ear on the mouse back". The goal is to create a substitute which supplies an individual therapy for patients with regeneration, remodeling and growth potentia…
