We computed the electronic transport properties of a structure analogue to graphene monoxide using combining non-equilibrium Green’s function and density functional theory methods. These properties were transmission spectrum and current – bias voltage characteristics, along with density of states and projected density…
The composite right/left-handed (CRLH) transmission line (TL) is presented as a general TL possessing both left-handed (LH) and right-handed (RH) natures. RH materials have both positive permittivity and positive permeability, and LH materials have both negative permittivity and negative permeability. This paper aims…
We investigate a planar heterostructures based on gapless graphene and its gap modifications such as a single single heterojunction, a quantum well, and a superlattice. We focus on electron properties of these heterostructures within the envelope wave functions. A new phenomena such as valley-polarized currents along…
Nowadays, novel applications for polyaniline (PANI) make new demands on its morphology controlling, and designing novel PANI or PANI composite polymeric materials has been more and more attractive. In this work, octaaminophenyl polyhedral oligomeric silsesquioxane (POSS) was employed to prepare nanostructured PANI com…
In this study, a smart single-layer graphene sheet (SLGS) is analytically modeled and its buckling is controlled using coupled polyvinylidene fluoride (PVDF) nanoplates. A voltage is applied to the PVDF nanoplate in thickness direction in order to control the critical load of the SLGS. Electric potential distribution…
Abstract The front cover artwork is provided by the group of Prof. Roland Winter at TU Dortmund University. The image shows the effect of pressure on protein′s energy landscape, which is controlled by the hydration sphere. Read the full text of the article at 10.1002/cphc.201500669
Gold has untapped potential in terms of catalytic chemoselectivity. In this chapter, the selective action of supported gold in the hydro- genation of functionalized nitroarenes and hydrodechlorination of chloroarenes is analyzed in detail. Hydrogen/gold interactions are examined, and the crucial catalyst structural an…
Abstract This research was aimed to know antimicrobial activity of edible film from jackfruit’s straws. Previously, edible films has been enriched by temulawak juice with various concentration (2%, 4%, 6%, and 8%). Antimicrobial activity toward microorganism on galamai (all of microorganism and osmophilic group) has b…
We have succeeded in the first direct probe of the change in the electronic structures of La@C 82 superatoms upon clustering by scanning tunneling microscopy/spectroscopy (STM/STS). An array of ∼1.3-nm-diameter glycine nanocavities self-assembled on a Cu(111) surface was used as a template. Isolated La@C 82 superatoms…
Since the pioneer work of M. Haruta and G. J. Hutchings on gold as a catalytically active metal [1-3], enthusiasm to improve the understanding of new catalytic processes based on gold was observed. High metal dispersion is of importance to obtain an interesting catalytic activity. In the case of gold due to its low me…
A novel diacetylene–containing main chain-type polymer, poly[2,6-bis(4-propargyl-oxy-benzoyl)pyridine] (P 1 ), was synthesized via oxidative coupling reaction with a new propargyl-terminated monomer, 2,6-bis(4-propargyl-oxy-benzoyl)pyridine (M 1 ), which was incorporated a substituted pyridine into the molecular chain…
Taxols are anti-cancer chemotherapy drugs. 10-Deacetyl Baccatin III (10-DAB III) is an important intermediate for both Paclitaxel and Docetaxel, two of the best anti-cancer drugs ever invented. 10-DAB III is one of the several taxols, which can be easily extracted from Yew Tree leaves ( Taxus baccata ), so it became a…
The aim of this research was the identification of biologically active secondary metabolites isolated from rare plant species Pulsatilla patens (L.) Mill. and cultivated Pulastilla vulgaris Mill. (Ranunculaceae). Chromatographic fractionation of the ethanolic extract of the roots of P. patens resulted in the isolation…
In response to the urge for multidisciplinary development of computational composites, designers and material scientists are increasingly involved in collaborative projects to valorize these technology-push materials in the early stages of their development. To further develop the computational composites, material sc…
This paper describes the synthesis of carbon nanoparticle (CNP) from natural sources such as kitchen soot, synthesis of a chromophoric system {5-[4-(dimethylamino) benzylidene]-4-oxo-2-thioxo1, 3-thiazolidin-3-yl} acetic acid and its incorporation into β-cyclodextrin (β-CD) through the esterification of the hydroxyl g…
As potential hydrogen storage mediums, ammonia borane and its derivatives have been paid an increasing attention owing to their higher hydrogen capacities and facile dehydrogenation properties under moderate conditions. In this chapter, we presented extensive studies on thermodynamic tailoring of dehydrogenation of me…
The activity concentrations of natural gamma-emitting radionuclides 238U, 232Th and 40K in soils from 7 sampling sites each in Ondo and Lagos States, southwestern Nigeria have been measured by using a well calibrated Hyper Pure Germanium Detector (HPGe). The mean activity concentration values of 39.24±1.12, 52.86±1.40…
Purpose – Local wall thinning is one of serious problems in aged power generating plants. As the thinning grows inside the pipes, it is difficult to detect and evaluate it from the outer surface of pipe. The purpose of this paper is to evaluate the method of semi-ellipsoidal wall thinning geometry on the back surface…
Described in this review are our electron-microscopic, energy dispersion, and optical (IR absorption and low-temperature (4.5 K) photoluminescence) investigations of layered InSe and GaSe crystals intercalated using the considered below methods with various concentrations of hydrogen or hydrogen-containing molecules (…
Two chiral (A)6B-typed supramolecular cages were constructed from hydrogen-bonded C6 -symmetric zinc porphyrin hexamers and chiral C3-symmetric pyridyl hexadentates with a core of 1,3,5-triphenylbenzene. Circular dichroism and molecular simulations revealed that the symmetry of the supramolecular cages switched from p…
