New micellar macrocontrast agents with improved contrast at high frequencies were designed by grafting a gadolinium based contrast agent onto functional stealth micelles formed by poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) in water. As evidenced by relaxometry measurements and the hemolytic CH50 test, the…
Coir fiber reinforced polypropylene composites were manufactured using a single extruder and an injection molding machine. Raw coir was chemically treated with benzene diazonium salt to increase its compatibility with the polypropylene matrix. Both raw and treated coir fiber was utilized and five levels of fiber loadi…
The ability of planar solid oxide fuel cells (SOFCs) with lanthanum strontium vanadate (LSV, )/yttria-stabilized zirconia (YSZ) and LSV/gadolinium-doped ceria (GDC) anodes to use a simulated coal syngas fuel stream containing was investigated at 800 and . The results were compared to SOFC performance in and simulated…
Nowadays assembly approaches are recognized as being the main working tool of bottom up chemical nanotechnology. The assembly of strongly emitting semiconductor nanocrystals can be performed on flat, porous and spherical surfaces and thus are very important for thin-film technologies, doping of mesoporous materials, m…
The bulk morphologies formed by a new class of charged block copolymers, 75 vol % fluorinated polyisoprene (FPI) – 25 vol% sulfonated polystyrene (PSS) with 50% sulfonation, are characterized, and the fundamental underlying forces that promote the self-assembly processes are elucidated. The results show how the bulk m…
The complex [(dmcb)(2)Ru(dppz)](PF(6))(2) shows unexpected luminescence in water implying fundamentally different excited state relaxation pathways than are typically observed for complexes of this kind.
Silver-containing oxide coatings on AZ31 Mg alloys were fabricated by microarc oxidation (MAO) in -containing sodium silicate -based electrolyte, and their physical and chemical properties were investigated, particularly focusing on corrosion resistance and antibacterial activity. The porous oxide coatings consisting…
In this paper, we report the synthesis, structure, and electrical conductivity of a novel series of Mo and rare earth (RE = Y, Sm, Gd)-doped compounds of the nominal chemical formula of Ce0.9−x RExMo0.1O2.1–0.5x (x = 0.2, 0.3) (CRMO). The formation of cubic fluorite-like structure was confirmed by powder X-ray diffrac…

The structure and luminescence properties of a well-known trinuclear Au(i) imidazolate complex are determined for the first time along with its interaction with the organic π acid perfluoronaphthalene in the solid state and solution.
Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP) has been exploited to hydrophilize PEEK. The ketone groups on the PEEK surface were reduced to hydroxyl groups which were converted to bromoisobutyrate initiating sites for SI-ATRP. The modification steps were followed by contact angle measurements and X…
Crystal engineering of pharmaceuticals through co-crystallization provides a new strategy for altering the physical and chemical properties of solid forms of active pharmaceutical ingredients (APIs). The understanding of structure–property relationship of co-crystals containing chiral pharmaceutical agent (PA) and co-…
We use the hyper-netted chain approximation of liquid state theory to analyze the evolution with density of the pair correlation function in a model of soft spheres with harmonic repulsion. As observed in recent experiments on jammed soft particles, theory predicts an ‘anomalous’ (nonmonotonic) evolution of the intens…
We have investigated emulsions stabilised solely by partially-hydrophobised fumed silica particles which consist of a mixture of primary particles and irregularly-shaped fused aggregates and larger agglomerates. The particle wettability is controlled by varying the extent of hydrophobisation of their surfaces. This, i…
The process of hydrogen desorption from graphane (graphene sheet saturated by hydrogen adsorbed from both sides) has been studied using the method of molecular dynamics. The temperature dependences of the time of desorption onset for various hydrogen coverages on graphene are calculated and the corresponding activatio…
A phase field model based on the time-dependent Ginburg–Landau equation (TDGL) is developed to investigate the electrocaloric effect (ECE) of PbZr0.8Ti0.2O3 (PZT) thin film with a multidomain structure. The rhombohedral domain morphology is obtained through numerically solving the TDGL equation with periodic boundary…
Nanoliposome can be designed as a drug delivery carrier to improve the pharmacological and therapeutic properties of drug administration. (188)Re-labeled nanoliposomes are useful for diagnostic imaging as well as for targeted radionuclide therapy. In this study, the in vivo nuclear imaging, pharmacokinetics and biodis…
We present the one-dimensional polymeric structures of [Cu(SePh)]∞1 and [Cu(SeMe)]∞2 that were solved by using powder X-ray diffraction data. Using a field-effect transistor (FET) set-up, the hole mobility of complex 1 was found to be 4 × 10−2 cm2 V−1 s−1, comparable to that of regioregular poly(3-hexylthiophene) (P3H…
By means of molecular dynamics simulations, we study the structure and the dynamics of a microscopic model for colloidal gels at low volume fractions. The presence of directional interactions leads to the formation of a persistent interconnected network at temperatures where phase separation does not occur. We find th…
Full control in size distribution and surface chemistry of Si nanocrystals (NCs) allows the high efficiency of visible light emission. The NC synthesis and subsequent surface modification with organic monolayers are performed in a single step by laser chemical method. Interestingly, it is found that the distinct emiss…
