Due to their novel physico-chemical characteristics, semi-conductor nanocrystal quantum dots (QDs) provide an advantageous perspective towards numerous different consumer and medical applications. The most notable potential application of QDs is their use as therapeutic and diagnostic tools in nanomedicine. Despite th…
Molten salts are a kind of inorganic ionic liquid, which have advantages of a wide liquid range, negligible vapor pressure, good solubility characteristics, non-flammability, excellent thermal and chemical stability, and more importantly, they are low-cost and recyclable. These advantages have aroused an appealing gre…
Poly(vinyl alcohol) (PVA) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene (p-G) in a PVA aqueous solution. PVA macroradicals formed by sonochemical degradation of the PVA solution were successfully trapped by graphene and grafted onto its surface. This was confirmed by transmission e…
Doped strontium titanates have been widely studied as potential anode materials in solid oxide fuel cells (SOFCs). The high n-type conductivity that can be achieved in these materials makes them well suited for use as the electronically conductive component in SOFC anodes. This makes them a potential alternative to ni…
In this study we report the first example of phosphoester bond hydrolysis in 4-nitrophenyl phosphate (NPP) and bis-4-nitrophenyl phosphate (BNPP), two commonly used DNA model substrates, promoted by metal-substituted polyoxometalates (POMs). Different transition metal and lanthanide ions were incorporated into the Wel…
The solid-state structure of ammonia borane is held together by an intricate N-H···H-B proton-hydride bonding network. These intermolecular interactions have long been considered to mediate the release of hydrogen from this material. Here we reveal the silent but important role played by B-H···H-B interactions in the…
New Aurivillius ferroelectrics Na0.5La0.5Bi2Nb2−xWxO9 (NLBN-W, x = 0, 0.01, 0.02, 0.03, and 0.05) by lanthanum (La3+) and tungsten (W6+) co-substitution were prepared by using a solid-state reaction process. The crystal structure of Na0.5La0.5Bi2Nb1.98W0.02O9 (NLBN-W-0.02) was refined by the Rietveld method with powde…
The mechanism of the horseradish peroxidase (HRP)–H2O2-catalysed polymerisation of aniline in the presence of AOT vesicles was investigated. AOT (= bis-(2-ethylhexyl)sulfosuccinate) served as vesicle-forming surfactant and dopant for obtaining at pH = 4.3 and room temperature within 24 h under optimal reaction conditi…
4.7 nm Gold nanoparticles (AuNPs) capped with mesogenic ligands, dispersed in homeotropically aligned smectic A liquid crystal (LC), reversibly form arrays of aggregates with micron-scale periodicities over macroscopic areas at the nematic to smectic A phase transition (TN-SmA). AuNPs with a mixed capping layer of 4′-…
Graphene has been attracting strong attention due to its interesting structure and properties and important applications in many areas. The process of the oxidation of graphite into graphene oxide (GO) and the subsequent reduction of GO into graphene is regarded as an effective process to produce graphene on a large s…
Silver-titanium dioxide core-shell (Ag@TiO2) nanoparticles were prepared via a reduction reaction of silver nitrate followed by a sol-gel process of titanium tetraisopropoxide (TTIP). The silver core was prepared from 10 ml of 5-mM silver nitrate solution with hydrazine as a reducing agent, and cetyltrimethylammonium…
An Au(25) cluster protected by azobenzene derivative thiolates (S-Az) ([Au(25)(S-Az)(18)](-)) was synthesized with the aim of producing a photoresponsive Au(25) cluster. The matrix-assisted laser desorption/ionization mass spectrum of the product revealed that [Au(25)(S-Az)(18)](-) was synthesized in high purity. Opti…
Two series of multivalent octasilsesquioxane glyco- and peptido-conjugates were synthesized using the photoinduced free-radical thiol-ene coupling (TEC). The first series was obtained by coupling C-glycosylpropyl thiols and cysteine containing peptides with the known octavinyl octasilsesquioxane while the second serie…
Peptide binding to a graphene sheet is studied by a coarse-grained approach. All-atom molecular dynamics (MD) is used to assess the adsorption energy (e.g. binding) of each amino acid with graphene. The relative adsorption energy of each residue is normalized to describe its coarse-grained interactions with graphene w…
Ceria based oxides are regarded as key oxide materials for energy and environmental applications, such as solid oxide fuel cells, oxygen permeation membranes, fuel cell electrodes, oxygen storage, or heterogeneous catalysis. This great versatility in applications is rendered possible by the fact that rare earth-doped…
BACKGROUND: Carbon nanotubes (CNTs) are novel materials with considerable potential in many areas related to nanomedicine. However, a major limitation in the development of CNT-based therapeutic nanomaterials is a lack of reliable and reproducible data describing their chemical and structural composition. Knowledge of…
We have developed simple and green electrochemistry to synthesize Ag nanostructures with high purity, good crystallinity and smooth surface for applications as super-SERS (surface-enhanced Raman scattering), SERS-active substrates and with highly effective antimicrobial activities. This synthesis takes place in a clea…
The effects of alginate-based [sodium alginate, 0-2% (w/v), glycerol, 0-2% (w/v) and sunflower oil 0.025% (w/v)] and gellan-based [gellan, 0-1% (w/v), glycerol, 0-1% (w/v) and sunflower oil 0.025% (w/v)] edible coatings on fresh-cut pineapple were evaluated by response surface methodology (RSM). Weight loss, firmness…
The effect of different concentrations of chitosan and chitosan nanoparticles as active coating on microbiological characteristics of fish fingers during frozen storage at -18°C were studied. Results indicated that, uncoated fish fingers (T1) and that coated with commercial edible coating (T2) had higher total bacteri…
We consider the stochastic Allen-Cahn equation driven by mollified space-time white noise. We show that, as the mollifier is removed, the solutions converge weakly to 0, independently of the initial condition. If the intensity of the noise simultaneously converges to 0 at a sufficiently fast rate, then the solutions c…
