The endothelium bares a paramount therapeutic and diagnostic significance in vascular disease. The current work presents a novel strategy based on the use of superparamagnetic nanoparticles to obtain an endothelial cell lining on the luminal surface of vascular conduits, which can be detected non-invasively in a clini…
This study clarifies the mechanism of the hollow structure formation in the simple self-templating preparation of monodispersed hollow silica structures; the role of the polarity of washing solvent in creating the hollow structure is emphasized.
Folate appended sterically-stabilized liposomes (FA-SL) were investigated for tumor targeting. Liposomes were prepared using HSPC, cholesterol and FA-polyethylene glycol (PEG)-SA. The liposomes with polyethylene glycol (PEG) without folic acid which has similar lipid composition were used for comparison. Liposomal pre…
Highly stable Eu(III) and Tb(III) complexes, emitting in the red and green visible regions, respectively, have been anchored onto a single SiO(2) transparent layer, yielding ca. 40 nm thick films; this allows high loading of tailored proportions of the red and green emitters within the films and results in highly unif…
In this study, Ga-doped (GZO) films deposited on a sapphire utilizing magnetron cosputtering method using and targets were demonstrated. The results revealed that the resistivities of the GZO films reduced by at least two orders of magnitude after the thermal annealing. The reduction in resistivity could be attributed…
Diatoms are unicellular photoautotrophic eukaryotes that play an important role in ecology by fixing large amounts of CO2 in the oceans. Because they evolved by secondary endocytobiosis-- a process of uptake of a eukaryotic alga into another eukaryotic cell--they have a rather unusual cell biology and genetic constitu…
An impure-phase GdAlO 3 usually remains in the product of gadolinium aluminum garnet (GAG) powder as synthesized. In this study, an attempt to prepare a stable GAG pure-phase powder by substituting small cations ( Tb 3 + , Y 3 + , or Lu 3 + ) at the dodecahedral sites or the substituting the large cation ( Ga 3 + ) fo…
Meso-scale visual observations were conducted to investigate the process of frost formation on both bare and hydrophobic coated copper surfaces, which had contact angles of 56° and 110°. The experiments were carried out for −20−0°C surface temperatures, 19−22°C ambient air temperatures, and 15−85% relative humidities.…
The charge-carrier mobilities for three Ni bis(dithiolene) complexes have been determined using the steady-state space-charge limited current technique. A high mobility of 2.8 cm2 V–1 s–1 was observed for one compound, which exhibits a π-stacked columnar structure, in an annealed unsymmetrical melt-processed device. E…
A zinc-dependent acylase, D-aminoacylase from Escherichia. Coli, displays a promiscuous activity to catalyze the carbon-carbon bond formation reaction of 1,3-dicarbonyl compounds to methyl vinyl ketone in organic media.
Molecular dynamics simulations are reported for the four component nematic liquid crystal mixture E7, which is used commercially. We are able to show the growth of a nematic phase directly from an isotropic liquid over a 100 ns period for an all-atom model, and study orientational and dipole order within the nematic p…
In the present study, RGD peptide was coupled with ferulic acid (FA) liposomes for binding to monocytes and neutrophils in peripheral blood for brain targeting in response to leukocyte recruitment. Cholesterol (Ch) was esterified with succinic anhydride to introduce a carboxylic end group (Ch-COOH). Soybean phosphatid…
The statistical damage model presented by the authors in the previous article of this series is used to formulate analytical constitutive relations for the hardening and softening phases of two-dimensional lattices. An alternative approach to the classical damage parameter approach is presented here. A semi-empirical…
Simple oligopeptides that self-assemble into homogeneous nanotubes can be directed to further assemble into macroscale parallel arrays through protein "salting out" strategies.
Degradation of phenol in water was carried out by ultrasonic irradiation in the presence of the composite particles of titanium dioxide (TiO 2 ) and activated carbon. Degradation of phenol as well as adsorption of phenol on the particles occurred at the same time. The amount of adsorbed phenol on the particles was est…
The application of colloidal and nanoparticulate carrier systems in the biomedical field has changed the definitions of diagnosis, treatment, and disease management. Carrier systems such as liposomes, polymeric particles, and micro-emulsion droplets are used for the sustained release of drugs, pesticides, fragrances,…
Two series of rare-earth isophthalates of the general formula, [M(2)(H(2)O)][{C(6)H(4)(COO)(2)}(2){C(6)H(4)(COOH)(COO)}(2)].H(2)O, M=La (I), Pr (Ia), and Nd (Ib) and [M(2)(H(2)O)(2)][{C(6)H(4)(COO)(2)}(3)].H(2)O, M=Y (II), Gd (IIa), and Dy (IIb) have been prepared by the reaction of the corresponding trivalent lanthan…
Highly luminescent and stable calixarene (CA[n], n = 4, 7) coated silica nanospheres englobed with CdTe nanocrystals were prepared via a sol–gel technique in aqueous media, and were characterized by luminescence spectroscopy, ultraviolet-visible spectroscopy (UV-vis), FT-IR spectroscopy, transmission electron microsco…
A new method was developed for the conjugation of multivalent dendritic groups to polymer vesicle surfaces.
The programmed assembly of molecules into supramolecular polymers is of great interest for developing stimuli-responsive "smart" materials. Controlling the morphology, dynamics and responsiveness of such materials is essential for future applications. It, however, necessitates fundamental understanding of non-covalent…
