Bioactivity guided isolation of oxypregnane-oligoglycosides (calotroposides) from the ethanolic extract of root bark of <italic>Calotropis gigantea</italic> (L.) Dryand. with purple flowers has been performed and isolated pure compounds has been evaluated for anticancer activity.
We report first principle calculations about the NO oxidation mechanism on Pt <sub>n</sub> /γ-Al <sub>2</sub> O <sub>3</sub> (110) with an aim to improve the understanding of the catalytic activity and the catalytic process.
Acidic dissolution of ferritic stainless steels is simulated using the ab initio based Monte Carlo technique. This approach aims to reach a better understanding of the effect of alloying elements on the acidic dissolution of SS at the microscopic scale. The dissolution probability of a surface atom is shown to depend…
The present article reports the results of studies related to the synthesis of MgFe2O4 nanocomposite powder by solution combustion process using mixture of fuels containing urea (U) and ammonium acetate (AA). The effect of mixture of fuel and sintering temperature on phase formation, structural, morphological and magn…
Partly graphitized AC materials are porous structures with high energy density and power density compared to commercial AC in the absence of conductive agent. Energy and power densities of 48.6 W h kg <sup>−1</sup> and 3600 W kg <sup>−1</sup> can be maintained at the potential window of 1.5 V.
In this paper are investigated microstructural, phase, physical and mechanical properties of mullite ceramics obtained from clay and Bayer electrofilter fines. Clay and alumina were mixed in such ratio that provides the amount of AlO23 and SiO2 corresponding composition of mullite. One mixture was manually mixed and o…
It was found in this study, that ionizing beta radiation has a positive effect on the mechanical properties of poly(ethylene). In recent years, there have been increasing requirements for quality and cost effectiveness of manufactured products in all areas of industrial production. These requirements are best met with…
(OH)Cl 2D layers are arranged from ABAB-type for compounds 1 and 2 to AA'B'B-type for 3 with smaller cation radii. Magnetic measurements show that 1 belongs to an antiferromagnetic material, while 2 and 3 have weak ferromagnetic properties with unsaturated ferromagnetism originating from spin-canting below the transit…
Global ecological concerns have resulted in an interest in renewable natural materials. Composites based on high density polyethylene (HDPE), wood fiber (Veneer) and containing coupling agents like nanoclay (NC) and poly-ethylene-co-glycidyl methacrylate (PEGMA) were made by melt compounding and then injection molding…
We present a new simulation method for the calculation of crystal nucleation rates by computer simulation. The method is based on the use of molds to induce crystallization in state points where nucleation is a rare event. The mold is a cluster of potential energy wells placed in the lattice positions of the solid. Th…
New tetrameric alkylzinc organophosphates of a drum-like structure and novel aggregates based on alkylzinc organophosphates with incorporated zincoxane units were synthesized and structurally characterized.
Au <sub>N</sub> quantum cluster sensitization of Er <sup>3+</sup> photoemission in silica is boosted by H passivation of Si dangling bonds around the clusters.
Since the beginning of the 20th century a controversy has been continuously revived about the existence of the Zenneck Wave. This wave is a theoretical solution of Maxwell’s equations and might be propagated along the interface between the air and a dielectric medium. The expected weak attenuation at large distance ex…
Comparison of eight simple but robust superhydrophobic coatings in a wide space of parameters, helpful for planning correct experiments.
A simple method that enables the direct fabrication of few layer graphene on SiO <sub>2</sub> /Si substrates with precise control of layer thickness by implantation of C ions is explored.
Among the NbO <italic>x</italic> modified MnCo <sub>2</sub> O <italic>x</italic> catalysts by co-precipitation, MnCo <sub>2</sub> Nb <sub>0.5</sub> O <italic>x</italic> presented high activity, N <sub>2</sub> selectivity and H <sub>2</sub> O resistance for NH <sub>3</sub> -SCR reaction at low temperatures.
The development of luminescent materials is of critical importance to human life. The recent discovery of aggregation-induced emission (AIE) has brought forth revolutionary changes in the role aggregation plays and has inspired research interest in AIE fluorogens (AIEgens) and their potential applications. Due to thei…
The fabrication and characterization of a localized surface plasmon resonance (LSPR) based optical nanosensor, which utilizes highly ordered gold nanoparticles as transducers are presented in this work. The nanoparticles are synthetized using nanodimpled aluminium templates, which were prepared by a selective chemical…
We examined the mineralization performance of a nacre protein, AP7, within seawater mineralization assays that form aragonite and magnesium calcite. Under these conditions AP7 forms hydrogel particles that vary in size and complexity depending upon ionic conditions. These hydrogels “hijack” the mineralization process…
