The perturbation of a dithienylethene system by a ruthenium carbon-rich system, and vice versa, was used to reach a unique and sophisticated light- and electro-triggered multifunctional switch featuring multicolor electrochromism, electrocyclization at remarkably low voltage, and photo/electro tuning of electronic com…
Synthesis and characterization of pine needles reinforced thermosetting resin (Resorcinol‐Formaldehyde) which is most suitable as composite matrix has been reported. The polycondensation reaction between resorcinol and formaldehyde (RF) in different molar ratios has been applied to the synthesis of RF polymer matrix.…
Recent studies have shown that the release properties of vincristine encapsulated in large unilamellar vesicles (LUV) can be regulated by varying the drug-to-lipid (D/L) ratio. In this work it is shown that the drug-to-lipid ratio technique for regulating drug release also applies to doxorubicin encapsulated in LUV. I…
The performance and comfort factors of garments during usage are very important. Generally, the comfortable stretching of fabrics according to body movements as well as recovery after stretching, are good desirable properties. In recent years, due to the demand for more comfortable clothing, which is more adjustable t…
An important feature of biological systems is their response to external stimuli with subsequent changes in properties and function. The ability to “engineer” adaptiveness into next-generation materials is becoming a key requirement and challenge in chemistry, materials science and engineering. Recently we have descri…
Nuclear magnetic resonance ͑NMR͒ measurements were made on aqueous vanadate solutions to characterize speciation as a function of pH and vanadate concentration.Additionally, potentiodynamic polarization measurements were carried out on Al alloy 2024-T3 in 50 mM NaCl solutions in which pH and vanadate concentration wer…
Polyurethane (PU) foam is a common material used in seats, sofas and mattresses, etc. However, the use of PU foam presents some problems concerning comfort and recycling. Compared with PU foam, warp knitted spacer fabrics can solve these problems. This paper presents work in the development of the warp knitted spacer…
We present an experimental analysis of the topological properties of a nematic liquid crystal in the vicinity of small cylindrical objects (micro-rods), dispersed in the nematic liquid crystal 5CB (4-n-pentyl-4-cyanobiphenyl). Depending on the type of liquid crystal anchoring on the surfaces of micro-rods, we have obs…
The self-limiting redox reaction of carbon nanofoam substrates with permanganate at room temperature in neutral-pH solutions produces conformal nanoscale deposits throughout the macroscopic thickness of the nanofoam structure. The nanoscale morphology ranges from layered ribbons and rods for a 4 h deposition to polycr…
Five structurally related europium(iii) complexes of heptadentate macrocyclic ligands bearing azaxanthone or azathiaxanthone chromophores have been evaluated comparatively as responsive probes of the intracellular environment. Protein binding (HSA) and oxy-anion binding constants have been measured by titrimetric anal…
Etoposide and nanoparticle formulations were labeled with Tc-99m and their biodistribution and pharmacokinetics were studied after intravenous administration in healthy mice and rabbits respectively. Etoposide was rapidly cleared from the body, while the disposition of nanoparticles was slower. A higher proportion of…
Here, we synthesized highly stable DNA-embedded Au/Ag core-shell nanoparticles (NPs) by a straightforward silver-staining of DNA-modified Au nanoparticles (AuNPs); unlike conventional DNA-surface modified NPs that present particle stability issues, DNA-embedded core-shell NPs offer an extraordinary stability with nano…
Technical advances in the field of colloidal nanocomposite particles over the past two years are briefly reviewed. Particular emphasis is given to organic–inorganic nanocomposite particles in which the organic phase is a vinyl polymer and the inorganic phase is typically silica. Such nanocomposite particles have been…
Gd(3+)-functionalized near-infrared emitting quantum dots were synthesized as a dual modal contrast agent for in vivo fluorescence imaging and magnetic resonance imaging.
The epoxidation of alkenes was successfully catalyzed by a recyclable and environmentally benign catalytic system: [π-C5H5N(CH2)15CH3]3[PW4O32]/H2O2/ethyl acetate/olefin
Six materials, (EDT-TTF)(4)BrI(2)(TIE)(5) (1, where EDT-TTF = ethylenedithiotetrathiafulvalene and TIE = tetraiodoethylene), (EDST)(4)I(3)(TIE)(5) (2, where EDST = ethylenedithiodiselenadithiafulvalene), (MDT-TTF)(4)BrI(2)(TIE)(5) (3, where MDT-TTF = methylenedithiotetrathiafulvalene), (HMTSF)(2)Cl(2)(TIE)(3) (4, wher…
Three derivatives of ouabain, digoxin and proscillaridin A containing the carboxylic group instead of the lactone moiety were synthesized and examined for cytotoxicity in human breast cancer cells. Evaluation of the cytotoxicity of these compounds employing an MTT assay and inhibition of [3H]thymidine incorporation in…
The prospect of building a future energy system on hydrogen has stimulated much research effort in developing hydrogen storage technologies. One of the potential materials newly developed is sodium amidoborane (NaNH2BH3) which evolves ∼7.5 wt% hydrogen at temperatures as low as 91 °C. In this paper, two methods of syn…
This article presents general characteristics and current applications of regenerated bamboo fibre in the textile industry. In the experimental part of the study, 100% regenerated bamboo yarns of six different counts (11.8, 14.8, 16.4, 19.7, 24.6 and 29.5 tex) were produced from bamboo fibre using ring yarn spinning t…
By using different types of ZnO thin films as seed layers, we systematically investigated the effects of seed layers on the morphologies and growth behaviors of ZnO nanorods by the vapor-phase transport method. It was found that ZnO nanorods can be grown on a variety of polycrystalline ZnO seed layers. The formation o…
