The reaction of the basic bismuth nitrate [Bi(6)O(4)(OH)(4)](NO(3))(6)·H(2)O with sodium methacrylate in DMSO gave [Bi(38)O(45)(OMc)(24)(DMSO)(9)]·2DMSO·7H(2)O (OMc = O(2)CC(3)H(5)), which is highly soluble in organic solvents. By copolymerization of the bismuth oxido cluster with methyl methacrylate transparent, radi…
Rhombic dodecahedral (RD) Fe3O4 nanocrystals (NCs) were for the first time prepared via a rapid and facile microwave-assisted route in the presence of ionic liquids (ILs). The reaction could be finished within 15 min at temperatures as low as 90 °C. A proper amount of ILs played a key role in the synthesis of pure RD…
Nanofibers formed by electrospinning provide very large surface areas which can enhance material performance in filtration and product separation. In this work, we explore atomic layer deposition (ALD) as a means to coat and protect electrospun nylon-6 nanofibers. Exposing nylon to trimethyl aluminum (TMA) during ALD…
In this paper, as a result of their laminar structure, dry BOPP windings have substantially anisotropic thermal conductivity. In the plane of the film, the thermal conductivity is about twice that of bulk polypropylene and about three times the thermal conductivity through the plane of the film. Three-dimensional fini…
A conventional parabolic reflector is converted into a flat one based on the discrete coordinate transformation. Instead of general beam-steering techniques, such as off-axis feeding, tilting the feed/reflector, or utilizing phase shift, we show an alternative way to manipulate the reflected emission through tuning tr…
The use of nanoparticles (NPs) has increased in the past few years in various fields, including defence, aerospace, electronics, biology, medicine, and so forth. and in applications such as diagnostic technology, bioimaging, and drug/gene delivery. Thus, human exposure to NPs and nanomaterials is unavoidable and will…
New columnar liquid crystals based on perylene bisimides (PBIs) were synthesized by introducing dendritic peptides onto the two ends of the imide. The self-assembly behaviour of PBIs in solution and in film was investigated through temperature-dependent and solvent-dependent ultraviolet-visible absorption spectroscopy…
The ability to solubilize insoluble inorganic pho- sphate compounds by Gluconacetobacter diazotrophicus was studied using different cul-ture approaches. Qualitative plate assays using tricalcium phosphate as the sole P-source showed that G. diazotrophicus produced solu-bilization only when aldoses were used as the C-s…
The synthesis of an azo-benzene glycoluril supergelator is reported. The control over the gel/sol state can be accomplished by irradiation and heat, but also (in a unidirectional sense) by incorporation of the glycoluril into a more stable supramolecular assembly.
We report the preparation of α- and κ-phase In2Se3 nanowires by thermal evaporation and investigation of their phase transformations in situ by synchrotron radiation X-ray diffraction (XRD) during a thermal annealing process. The κ-phase transformed into the α-phase at 500 °C and eventually transformed to high tempera…
The synthesis and characterization of lead telluride (PbTe) gels and aerogels with nanostructured features of potential benefit for enhanced thermoelectrics is reported. In this approach, discrete thiolate-capped PbTe nanoparticles were synthesized by a solution-based approach followed by oxidation-induced nanoparticl…
This research aims at reutilizing discarded plaster molds by using waste gypsum obtained from these molds as an inert filler in natural rubber. Its effects on curing characteristics were investigated in comparison with commercial gypsum and calcium carbonate. These fillers were characterized by an X-ray diffractometer…
A binary mixture of amphiphilic polypeptides with right- and left-handed helical blocks was self-assembled into a morphology of a nano round-bottom flask shape upon heat treatment. The tubulation occurred as a result of phase-separation into the tubule domain of the single component and the vesicle domain of the stere…
A cyclic tetranuclear cyclometallated iridium(III) complex using cyanide anions as bridging ligands and displaying a tetrahedrally distorted square geometry has been obtained with high yield; photo- and electrochemical characterizations show that most interesting properties of mononuclear cyclometallated iridium compl…
Oxygen-deficient luminescent mesoporous silica nanoparticles with uniform morphology/size and integrated mesoporosity-luminescent property in a single nanoparticle are successfully synthesized by a bottom-up self-assembly route followed by a post-calcination process, and can be used to facilely load/deliver drugs into…
A comparative study of the adsorption behavior of 4, 3, and 2 aminothiophenol on gold nanorod (AuNRs) solution and film substrates is carried out using surface-enhanced Raman spectroscopy (SERS) to provide information about the adsorption mechanisms of aminothiophenols on AuNRs. SERS from gold nanorods in solution for…
The diffusivity of a nanoparticle suspended in a liquid crystal is investigated in the limit of nematic ordering and under isotropic conditions. Molecular simulations are performed with the liquid-crystalline solvent represented at the level of Gay–Berne mesogens in the canonical (N,V,T) ensemble. The mesogen–colloid…
This chapter focuses on the description of nanostructured metal oxides representing the most common, diverse, and richest class of materials in terms of electronic structure and structural, chemical, and physical properties. Among such properties one can mention electrical, optical, optoelectronic, magnetic, thermal,…
A rapid microwave-assisted method was developed for the facile synthesis of a polyacid-conjugated Fe3O4 superparamagnetic hybrid. Field-emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, thermogravimetric and magnetic meas…
Au deposited on Ru(0001)-supported extended, continuous graphene moiré forms large 2-D islands at room temperature that are several nanometers in diameter but only 0.55 nm in height, in the apparent absence of typical binding sites such as defects and adsorbates. These Au islands conform to the corrugation of the unde…
