Local delivery of antiproliferative drugs encapsulated in biodegradable nanoparticles has shown promise as an experimental strategy for preventing vascular restenosis development. The general aim of this work was to develop polymeric nanoparticle carriers with bioadhesive properties, and to evaluate its adjuvant poten…
BF(2) capped dipyrrin dimers were synthesized and have been used to terminate oligomerization to form a series of controlled length oligomers; the crystal structures of the metal complexes were investigated and correlations between the structures and optical properties were established.
Experiments were conducted to determine how inhibiting forms of vanadate interact with complex Al alloy microconstituent intermetallics to impart corrosion protection. Cathodic polarization experiments on Al 2024-T3 indicate a strong correlation between inhibition and the presence of tetrahedrally coordinated vanadate…
Metal (Au, Cu)-modified Si nanowires (SiNWs) are superior catalysts for selective oxidation of hydrocarbons, while SiNWs are a powerful substrate support (enhance efficiency and selectivity) for nanocatalysts.
The luminescence properties of the three new stoichiometrically mixed lanthanide complexes, Sm1/2Eu1/2(PBI)3·bpy·H2O (1), Sm1/2Tb1/2(PBI)3·bpy·H2O (2) and Eu1/2Tb1/2(PBI)3·bpy·H2O (3) [HPBI = 3-phenyl-4-benzoyl-5-isoxazolone; bpy = 2,2′-bipyridine] have been compared with those of the analogous single lanthanide ion s…
The objectives of this paper was to discuss the latest development of nanotechnology, especially in food industries, to give clearer picture about the effect of nanotechnology in food industries and to highlight the latest applications of nanotechnology in food processing industry. However, the risk issues involving t…
A series of magnesium bis(amido-oxazolinate) complexes have been described. Reactions of six amido-oxazolinate ligand precursors, HNC(2)(Me)Oxa, HNC(2)(OMe)Oxa, HNC(2)(StBu)Oxa, HNPhOxa, HNPh(OMe)Oxa or HNPh(SMe)Oxa, with half molar equivalent of Mg(n)Bu(2) in hexane yield the magnesium bis(amido-oxazolinate) complexe…
Double-helical architectures obtained from achiral ligands and metal ions present supramolecular homochirality in the single -crystal state under constitutional self-sorting.

Epoxy matrix composites reinforced with recycled cellulose fibre (RCF) were fabricated and characterized with respect to their flexural and impact properties. Reinforcement of the epoxy by RCF resulted in a significant increase in the strain at failure, fracture toughness and impact toughness but only a moderate incre…
Quantum chemical and ab initio thermodynamic calculations were used to investigate the mechanism of CO oxidation on Au/TiO(2) and the geometric and electronic character of active sites. We show that CO oxidation over Au/TiO(2) might proceed via a two site mechanism with oxygen adsorbing and dissociating at the Au/oxid…
Single-walled carbon nanotubes (SWCNTs) wrapped with cellulose have been successfully prepared by the treatment of SWCNTs with a cellulose solution in the ionic liquid 1-butyl-3-methylimidazolium bromide. The obtained SWCNT complex can be dispersed in water, forming a stable solution with excellent biocompatibility. I…
An amphiphilic platinum(II)-containing diblock copolymer, with pH- and solvent-responsive micellization properties that could induce drastic UV-vis and emission spectral changes via modulation of Pt...Pt and pi-pi stacking interactions, has been demonstrated in both aqueous and organic media.
Two C3 symmetric tris(TTF) derivatives, based on a central unit containing the rigid core 1,3,5-tricarbonyl-benzene substituted with three 3,3′-diamino-2,2′-bipyridines, have been synthesized by a convergent strategy. Single crystal X-ray analysis of the precursor 3′-[(ethylenedithio-tetrathiafulvalenyl)formylamino]-2…
We have fabricated novel, food-grade anisotropic ‘lumpy’ micro-rods with micro-particle inclusions using an in-shear flow solvent attrition technique. Various micro-particle inclusions have been used in shellac and ethyl cellulose micro-rods which include sporopollenin microcapsules, porous silicas, yeast cells, sodiu…
An orange-emitting, long-persistent phosphor, , was developed. Afterglow of this phosphor decays more slowly than that of the conventional red-emitting, long-persistent phosphor, . After 420 nm excitation, the afterglow luminance is initially lower, but, after 8 min, gets higher than luminance of . Long afterglow resu…
Recently, to improve the properties of wood plastic composite (WPC), incorporation of nanofiller has been considered. In this study, hybrid composite of polypropylene/wood flour/nanoclay with different concentrations of nanoclay and maleated polypropylene (MAPP) as compatibilizer were fabricated in an internal mixer.…
Mixed ligand Ln2Cu2 tetranuclear complexes, [{LnCu(L4)(L5)(NO3)2}2] (L4− is a Schiff base ligand derived from o-vanilate, L52− is a nitromethyl derivative of L4−; LnGd(4), Tb(5), and Dy(6)), were synthesized by reacting the corresponding dinuclear complexes [LnCu(o-vanilate)2(NO3)3] with ethylamine in a nitromethane s…
The optimum luminescence and its relevant applications of phosphors are always challenged by the generation of multicolour lights in a single solid with a single-wavelength excitation. In this work, we initiated the preparation of novel core-shell CaWO4 microspheres co-doped with Na+ and Ln3+ (Ln = Tb, Sm, Dy, Eu) and…
The reaction of fluorous imino-alcohols {ON(R1,R2)}H (R(1) = Me, Ph; R(2) = Ph, CH(2)Ph, cyclohexyl, piperidinyl) with Zn(N(SiMe(3))(2))(2) (1 or 0.5 equiv) systematically led to bis(ligand) complexes Zn{ON(R1,R2)}(2) (1-9), which were isolated in 84-88% yield. Imino-alcohols {ON(R1,R2)}H react selectively with ZnEt(2…
