Some novel Schiff bases have been derived using aromatic aldehydes and aromatic amine in ethanol under acidic conditions. The geometry of these Schiff bases was established using various spectroscopic methods like infrared (IR), nuclear magnetic resonance (NMR) and mass spectrometry. The conductivity studies reveal th…
A simple and easy method was developed for preparation of large-scale free-standing mesoporous protein thin films through a filtration technique by using ultrathin metal hydroxide nanostrands as frames and pore templates. Composite nanofibrous dispersions of nanostrands and proteins were formed by assembling negativel…
We describe the formation of BaTiO3 superstructures from precursor nanoparticles and the use of ferroelectric properties to trigger a hierarchical growth mechanism. Without specific treatment, the precursor nanoparticles comprise of ferroelectric domains that are oriented randomly (domains of the same spontaneous pola…
We show, using α-glycine in an equi-volume methanol/water mixture as example, that the influence of solvent and solvent mixtures on crystal habits can be predicted by using Extended Interface Structure Analysis (EISA), a hybrid multiscale method based on molecular simulations and theoretical thermodynamic analysis of…
Integrated Coal Gasification Fuel Cell Combined Cycle (IGFC) is expected to be the most efficient power generation system in coal fired power generation systems [1,2]. The Japanese project of the Strategic Technical Platform for Clean Coal Technology (STEP-CCT) aims a target efficiency of 65% (HHV) with exergy recuper…
Instead of metal oxides or alloys, a novel co-assembled conducting polymer, polyaniline–poly(pyrrole), was employed and demonstrated significantly enhanced ethanol oxidation catalytic activities and stability on Pt-based catalysts, indicating a potential practical application in direct ethanol fuel cells with low cost…
Elastic and damping properties of AZ31 magnesium alloy sheet processed by high-temperature rolling were investigated. The specimen rolled at high temperature (798 K) exhibited the significant low basal texture intensity and the wide spread of the basal pole toward the RD and TD, compared with the specimen rolled at 57…
The microdomain structure of polystyrene-polymethylmethacrylate block copolymer (PS-b-PMMA) can be directed by a photochemically attached polymer surface layer. The photochemical attachment of the neutralization polymer on the silicon surface is a convenient and effective technique for interfacial energy control to pr…
We present a simple and straightforward method for creating a hierarchical structure in which the nanoscale roughness is derived from a microstructure. This hierarchical structure is at the backbone of almost all biomimetic functions. A liquid blend of a photocurable prepolymer and a functionalized polysiloxane is mou…
The explorative coordination chemistry of the bridging ligand TTF-PPB is presented. Its strong binding ability to Co(II) and then to Ni(II) or Cu(II) in the presence of hexafluoroacetylacetonate (hfac(-)), forming new mono- and dinuclear complexes 1-3, is described. X-ray crystallographic studies have been conducted i…
The high sensitivity of graphene to the adsorption/desorption of gas molecule, is at the very beginning of its exploitation. This sensitivity relies on the two-dimensional nature of graphene allowing a total exposure of all its atoms to the adsorbing gas molecules, thus providing the greatest sensor area per unit volu…
In this paper we investigated basic characteristics of gleyic soils of Banat and presented different interpretations and classification of these soils. Twelve profiles were analyzed to access their physical and chemical properties. Investigated humogley profiles were predominantly clayic with vertic properties and und…
We introduce an approach that combines the concepts of emulsion-templating and dewetting for fabricating polymersomes with a large number of compartments. The resultant polymersome gel behaves as a gel-like solid, but is a true vesicle suspended in an aqueous environment. Due to the thin membranes that separate the co…
A nanometer-sized raspberry-like architecture, consisting of an aggregation of repeated sequences of a three-dimensional gold nanoparticle (AuNP)-organic component-AuNP arrangement, has been prepared with a single-step procedure in an aqueous system involving the reduction of aurate to AuNPs by aniline. The raspberry-…
A standardized extract of the plant Caralluma fimbriata (Slimaluma?) is widely used in the management of obesity but its mode of action is not yet clarified. This study investigated the ability of Caralluma fimbriata extract (CFE) to modify pre-adipocyte cell division and thus the development of hyper-plastic obesity.…
Platinum is recognized as a harmless metal and is widely used in many industrial products. Recent studies have proposed that platinum in the form of nanoparticles has antioxidant properties, suggesting potential uses for platinum nanoparticles as additives in foods and cosmetics, with direct exposure consequences for…
A method for estimating Wilson parameters on the basis of solubility parameters and molar volumes has been adopted to correlate vapor–liquid equilibria of polar mixtures such as binary systems containing ethers, ketones, ethanol, and water. The correlation performances are examined and discussed.
We have demonstrated the glucan polymer-mediated syntheses of titania at room temperature, which is an energy-conserving and environmentally benign synthetic pathway. Wormhole-like particles (both rutile and anatase) with high surface areas and quasi-sphere-shaped particles (anatase) were obtained for chitosan, sodium…
Using in-situ emulsion polymerization, the exfoliated nanocomposites were prepared from vinyl acetate (VAc) and organic montmorillonite (OMMT) through five different experimental conditions. The different experimental conditions and OMMT had little effect on the structure of PVAc–OMMT, but significant effect on the dy…
Upon examination of shape memory alloy (SMA) actuation designs, there are many considerations and methodologies that are common to them all. A goal of CASMART’s design working group is to compile the collective experiences of CASMART’s member organizations into a single medium that engineers can then use to make the b…
