BACKGROUND: In vitro experiments on the functional roles of extracellular matrix (ECM) components usually involve the culture of cells on surfaces coated with purified ECM components. These experiments can seldom recuperate the spatial arrangement of ECM found in vivo. In this study, we have overcome this obstacle by…
The reliability of the gate oxide on large-area surface defects (trapezoid-shaped and obtuse triangular defects) in 4H-SiC epitaxial wafers is discussed. Time-dependent dielectric breakdown measurements revealed that a reduction in charge-to-breakdown (Q bd) occurred at a MOS capacitor including the downstream line of…
C1 domains are small zinc-binding structural units of approximately 50 amino acids, originally discovered as lipid-binding modules in protein kinase C (PKC) isoforms. C1 domains that bind and respond to the DAG/phorbol ester are termed as typical, and those that do not respond to DAG/phorbol ester are termed as atypic…
In this study, we investigated the use of composite patches to repair aluminum alloy double-lap joints. The carbon composite patches were cured using induction curing or oven curing. Joints were repaired using precured or cocured composite patches. The bond strengths of the different joints were compared. We also inve…
An approach is proposed to the preparation of magnetic sorption materials based on the synthesis and surface modification of nanomagnetite by organic compounds under microwave heating. The optimum conditions for the preparation of nanomagnetite are found, its structure and particle sizes are studied. Data on the stabi…
Based on first-principles calculations, the electronic, magnetic, and topological characters of manganese (Mn) doped topological insulator Bi2Te3 were investigated. The Mn substitutionally doped Bi2Te3, where Mn atoms tend to be uniformly distributed, was shown to be p-type ferromagnetic, arising from hole-mediated Ru…
Abstract The photophysical properties of rhenium selenide cluster complexes containing various nitrogen‐donor ligands (nitrile, azide, tetrazolate, and triazolate) are reported. These octahedral clusters are all based on the site‐differentiated [Re6Se8]2+ core and have the general formula [Re6Se8(PEt3)5L]n+ (L = nitro…
The current work is concerned with obtaining a new empirical model for the time-variable effective diffusion coefficient ( D eff ) by extraction from plant materials. It has been applied for describing a solid liquid extraction from Cotinus coggygria and compared with experimentally obtained extraction kinetics. The e…
Human mesenchymal stem cells (hMSCs) induced towards chondrogenesis develop a pericellular matrix (PCM), rich in type VI collagen (ColVI) and proteoglycans such as decorin (DCN). Individual PCM protein functions still need to be elucidated to fully understand the mechanobiological role of this matrix. In this study we…
ABSTRACT Silicon carbide hollow particle (SiCHS) reinforced vinyl ester matrix syntactic foams are prepared and characterized for compressive properties and coefficient of thermal expansion (CTE). Two types of SiCHS were utilized in 60 vol % to prepare syntactic foams. These SiCHS had ratio of inner to outer radius of…
Abstract MgO-templated mesoporous carbon (MgOC) with an average pore diameter of 38 nm was used as electrode material for a glucose-oxidizing anode. Anodic catalysts composed of a redox polymer, glucose oxidase, and crosslinkers were applied to MgOC-modified electrodes. The glucose oxidation current density on MgOC wa…
Development of safe and effective hydrogen storage systems becomes a critical factor for further implementation of fuel cell and hydrogen technologies. Among new approaches aimed at improving the performance of such systems, the concept of porous materials-based adsorptive hydrogen storage is now considered as a long-…
In this paper, four stilbene derivatives substituted with ester groups were synthesized and their two-dimensional (2D) self-assembled behaviors were investigated by scanning tunneling microscopy (STM) on the highly oriented pyrolytic graphite (HOPG) surface. The four target molecules are different in the symmetrical p…
Epipelic microphototrophs perform a range of ecosystem functions including biostabilization of sediments, regulation of benthic–limnetic nutrient cycling, and primary production. This review summarizes the most recent research of lake/pond phototrophic epipelic taxa and highlights the importance of an approach to iden…
In this paper, a novel method to determine the thickness of thin metal film is put forward which uses Surface Plasmon Resonance (SPR) phase detection method. The relations between the metal film thickness and the phases of the transverse magnetic (TM) and transverse electric (TE) polarization of the reflected light ar…
It is widely believed that Alzheimer's disease pathogenesis is driven by the production and deposition of the amyloid-β peptide (Aβ) in the brain. In this study, we employ a combination of in silico and in vitro approaches to investigate the inhibitory properties of selected arginine-rich D-enantiomeric peptides (D-pe…
Abstract We present a fluid-mechanical model of the coalescence of a number of elastic objects due to surface tension. We consider an array of spring–block elements separated by thin liquid films, whose dynamics are modelled using lubrication theory. With this simplified model of elastocapillary coalescence, we presen…
Biocompatible dysprosia aerogels were synthesized from DyCl3·6H2O and were reinforced mechanically with a conformal nano-thin-polyurea coating applied over their skeletal framework. The random mesoporous space of dysprosia aerogels was filled up to about 30% v/v with paracetamol, indomethacin, or insulin, and the drug…
The spiral phase plate etalon transmission function is calculated from the low-reflectivity to high-reflectivity regime. Two approximations are considered: thick-plate approximation and thin-plate approximation. The thick-plate approximation explicitly takes into account the angle between the azimuthally increasing su…
Bifacial n-type silicon solar cells typically feature two highly doped areas, namely, a boron-doped emitter and phosphorus-doped back-surface field (BSF). Complexity of the process sequence for forming these highly doped areas is one of the major obstacles for industrial application. This study investigates a POCl3-ba…
