Rare-earth octahedra have been previously synthesised using p-tert-butylcalix[4]arene as a cluster support. Introduction of a heteroatom bridge in the calixarene framework, with concomitant alteration to the nature of the metal binding pocket, influences lanthanide composition in the cluster.
In the present study, ion adsorption on the outer and inner surfaces of single-walled carbon nanotubes (SWCNTs) in different aqueous and organic electrolytes was analysed. It was found that the fundamental properties of tube size and electronic structure, particularly the transition between van Hove singularities (the…
Nanoparticles (NPs) may differ in reactivity and solubility and may interact with all kinds of endogenous proteins, lipids, polysaccharides, and cells. Based on experiences in inhalation toxicology, a series of tests was proposed for evaluation of the toxicity of NPs used in drug delivery systems Gold NPs (GNPs) can e…
-L-Arabinofuranosides are hydroxyproline (Hyp)linked sugar chains of extensin observed in plant cell wall fractions. Despite the broad distribution of -Larabinofuranosyl residues in plants, degradative enzymes have not yet been identified. In 2011, we cloned and characterized the first degradative enzymes for Hyp-link…
In recent years, the synthesis of CdS nanoparticle has attained great attention due to its unique size dependent optical, catalytical and electrical properties. CdS nanoparticles are II-VI group semiconductor in nature with a wide band gap. Simple, non toxic and environmental friendly method of its production has been…
In this study, synthesized polyols from refined cooking oil, one of the ingredients in producing polyurethane (PU) foam, were investigated. The effects of reaction time, pH and type of solvents used on the properties of the polyols were characterized by using gas chromatography mass spectrometry (GC-MS), Fourier trans…
Methods of MAX-phase synthesis and densifi cation - I Methods of MAX-phase synthesis and densifi cation - II Consolidation and synthesis of MAX phases by Spark Plasma Sintering (SPS): A review Microstructural examination during the formation of Ti3AlC2 from mixtures of Ti/Al/C and Ti/Al/TiC Fabrication of in situ Ti2A…
Thermal properties of flame retardant cotton fabric grafted by dimethyl methacryloy-loxyethyl phosphate were investigated by the atom transfer radical polymerization method. Thermal gravimetric analysis was used to explore the thermal decomposition mode of flamed retardant cotton fabric. The weight loss rate of the fl…
The inhibition efficiency (IE) of metronidazole (MZ)-Zn(II) system in controlling corrosion of mild steel in aqueous solution containing 60 ppm of Cl -ion has been evaluated by weight loss method. Weight loss study reveals that the formulation consisting of 140 ppm of MZ and 50 ppm of Zn(II) has 84% inhibition efficie…
A novel high-temperature synthesis of niobium oxide nanostructures has been developed through an amorphous intermediate that crystallizes into anisotropic crystalline structures through a complex mechanism of nucleation-dissolution-selective growth induced by seeded growth. The amorphous materials formed by the thermo…

Fluorescent polymer nanoparticles have been prepared by emulsion polymerization with a polymerisable anthrapyridone dye. This connects covalently to the polymer chains, preventing dye leakage. Amino groups were introduced into the nanoparticles by grafting with PEI (polyethyleneimine), following which folic acid was a…
Reversible fluorescence photoswitching of RSA-AZO dyad 1 was clearly demonstrated in an acidic aqueous solution. The fluorescence photoswitching mechanism is based on the reversible ring opening/closing reactions of the RSA unit induced by a photochromic pK(a) change along with the photoisomerization of the AZO unit.
The preparations and structures are described of four new polyoxostibonates, [Co(p-MeC(6)H(4)Sb)(12)O(28){Co(H(2)O)(3)}(4)]Cl(2)·6H(2)O, [Co(p-ClC(6)H(4)Sb)(12)O(28){Co(H(2)O)(3)}(4)]Cl(2)·22H(2)O, (PhCH(2)NMe(3))(2)[Zn(p-ClC(6)H(4)Sb)(12)O(28)Zn(4)Cl(2.54)Br(1.46)]·8MeCN·H(2)O and [BaCoH(4)(p-MeC(6)H(4)Sb)O(28)]·5H(2…
The bubble electrospinning is used to produce nanoparticles from several nano-meters to several hundred nanometers in diameter. Silk fibroin aqueous solution with low concentration is used in the experiment. The spinning process can be well controlled by temperature.
Micrometer-sized gold nanosheets (Au-NSs) were directly deposited on a large-scale at a solid–liquid interface using a modified solid matrix (SM) method. The reducing agent and the stabilizer were in the solid phase, and the oxidizing agent (HAuCl4) with an acetate ion as an additional stabilizer was in the aqueous ph…
Nano-composite, perovskite Ba(1- x - y)Sr(x)TiFe(y)O3, denoted as (BSTFe) in powder form was derived via sol-gel (SG) method followed by sintering at fixed temperature 750℃ for one hour. The chemical composition, morphology and structure of the powder samples were investigated by using X-ray diffraction (XRD), transmi…
The enthalpy recovery of an Epoxy/Carbon Nanotube systems (E/CNT) manufactured at low nanotube content, have been investigated by using Differential Scanning Calorimetry. Two different nanotube concentration were considered, 0.5 and 0.1 w/w and results compared with the behaviour of the neat epoxy material. Final resu…
ON BLENDS BASED ON PDLLA AND PVP. Poly(D,L-lactide), PDLLA, is a polymer with potential applications in medical, environmental, and pharmaceutical areas. Despite its versatility, the hydrophobicity limits its applications. To overcome this problem, one strategy is the preparation of blends with hydrophilic polymers su…
Dichroic optical spectroscopies and theoretical modelling have been used to describe the structure of aggregates of porphyrins in their gels in terms of: (i) the formation of helicoidal structures, (ii) the sign of the handedness, (iii) their extent and degree of structural order, and (iv) the annealing of the structu…
