In this review the preparation and adsorption phenomena specific to functionalized mesoporous silicas are discussed for designing the optimum structures of adsorbents for the removal of aqueous pollutants. The topics mainly described are control of spacing of functional groups on the surface, selective functionalizati…
A simple, rapid, cost-efficient and convenient method has been developed for synthesis of water-soluble CdTe quantum dots (QDs) under ambient atmospheric conditions. Using this method, the preparation of Te precursor and growth of CdTe QDs were achieved with one-step synthetic route. Under the optimal conditions, the…
A series of new aggregation-induced emission compounds with strong blue light-emitting properties derived from triphenylethylene were facilely synthesized by a Wittig–Horner reaction of bis(4-bromophenyl)methanone with diethyl 4-bromobenzylphosphonate, followed by a Suzuki reaction with arylboronic acids. Their maximu…
In this work, oxide nanoflakes with a maximum specific capacitance of are successfully synthesized by a facile chemical coprecipitation method. To enhance energy density, an asymmetric supercapacitor with high energy and power density has been constructed with oxide nanoflakes as the positive electrode and activated c…
The understanding, at the atomic level, of the role played by additives (dopants or promoters) in the chemistry of an industrial catalyst is a very complex and difficult task. We succeeded in this goal for the ethylene oxychlorination catalyst (CuCl(2)/gamma-Al(2)O(3)), used to produce dichloroethane, a key intermedia…
In this paper, three-dimensional mesoporous Zinc oxide (ZnO) hierarchical structures were fabricated from the thermal-decomposition of layered basic zinc carbonate (LBZC) precursors, which were synthesized by an urea hydrothermal method without a surfactant. X-ray diffraction (XRD) and scanning electron microscopy (SE…
A new nitronyl nitroxide bridged one-dimensional lanthanide complex [Tb(3)(hfac)(9)(NIT-2thien)(3)](n) (1) (NIT-2thien = 2-(2'-thienyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide) has been successfully prepared. Single crystal X-ray crystallographic analysis reveals that complex 1 consists of linear chains built u…
The concept of a Master Sintering Curve (MSC) is a strong tool for optimizing the sintering process. However, constructing the MSC from sintering data involves complicated and time-consuming calculations. A practical method for the construction of a MSC is presented in the paper. With the help of a few dilatometric si…
In the present study, hydroxyl functionalized manganese(III) Schiff-base; [Mn((OH)(2)-salophen)Cl] [(OH)(2)-salophen] = (N,N'-bis(4-hydroxysalicylidene)phenylene-1,2-diamine); has been covalently anchored on modified multi-wall carbon nanotubes (MWNTs); [Mn((OH)(2)-salophen)Cl]@MWNTs]. The new modified MWNTs have been…
Engineered nanomaterials i.e. materials deliberately manufactured on a nanoscale offer exciting new opportunities in technology and medicine. However, the increasing use of nanomaterials in society also raises concerns as to their possible adverse effects on human health and the environment. This review considers the…
Influences of oxygen partial pressure, PO2, of ambient atmosphere and temperature on surface tension of molten silver were experimentally investigated by an oscillating droplet method using an electromagnetic levitation furnace. We successfully measured surface tension of molten silver within a very wide temperature r…
This overview briefly surveys the practice of green chemistry in polymer science. Eight related themes can be discerned from the current research activities: 1) biocatalysis, 2) bio-based building blocks and agricultural products, 3) degradable polymers, 4) recycling of polymer products and catalysts, 5) energy genera…
Nanoparticles of the [Fe(NH(2)trz)(3)](tosylate)(2) spin crossover complex of 3-4 nm size were synthesized and dispersed in a nonionic surfactant. This colloidal system exhibits thermal spin crossover phenomena associated with a virtually first order transition. By thermal treatment the colloidal suspension can be tra…
Two cyanide-bridged alternated 1 : 1 Ru(III)/Mn(III) complexes structurally characterized as single-chain containing co-crystallized bulk anions and cations have been successfully assembled from [Mn(TPP)(H(2)O)(2)](+) and [Ru(acac)(2)(CN)(2)](-) blocks. Systematic investigation of their magnetic properties reveals typ…
Chalcogenides are an important class of semiconducting materials with applications and potential for application in many areas of technology. The availability of materials often depends on the processing methodologies available. The present article will focus on methods from single molecule precursors for binary chalc…
The hydrogen desorption behavior of pure iron with a body-centered-cubic (BCC) lattice and Inconel 625 with a face-centered-cubic (FCC) lattice was examined during tensile deformation using a quadrupole mass spectrometer in a vacuum chamber integrated with a tensile testing machine. Hydrogen and water desorption was c…
Here, we report fabrication of transparent graphene constructed carbon films (TGFs), from the botanical derivative camphor by controlled pyrolysis, for solar cell applications. TGFs show very good transparency in a wide range of wavelengths (0.3–2 μm) in contrast to indium tin oxide, which shows strong absorptions in…
Tin oxide nanoplates and nanoballs were fabricated using a cationic surfactant of cetyltrimethylammonium bromide (CTABr) as an organic supramolecular template and tin(IV) chloride as an inorganic precursor via the hydrothermal and conventional heating methods. Urea, which decomposes to ammonium and hydroxide ions duri…
In this paper, we describe a detailed study on preparation and characterizations of functional ionic liquid-gels and hydrogels of xanthan gum. When the 9.1–50.0 wt% solutions of xanthan gum in an ionic liquid, 1-butyl-3-methylimidazolium chloride (BMIMCl), were left standing at room temperature, they completely turned…
About six years ago, almost simultaneously, three independent groups reported the synthesis of a novel class of dendritic molecules. These molecules were equipped with a focal trigger; reaction at the trigger initiated the fragmentation of the dendrimer to its building blocks in a domino-like manner with consequent re…
