Surfactant controlled synthesis of magnesium oxide-tin oxide (MgO-SnO 2 ) nanocatalysts was carried out via the hydrothermal method. Concentration of sodium dodecyl sulfate (SDS) was varied while all other reaction conditions were kept constant same for this purpose. Furthermore, MgO-SnO 2 nanocatalysts were also prep…
Abstract The surface of a polyamide-12 (PA-12) foil was modified in order to improve the adhesive properties by two types of atmospheric pressure plasma sources. The samples were characterized using contact angle measurement, adhesive properties measurement and X-ray photoelectron spectroscopy (XPS). The ageing of the…
Calorimetric, Raman and electrical conductivity properties of alkali borates ( , Na) are studied as a function of composition and these show the presence of stiffness transitions and an intermediate phase which are driven by a combination of network dimensionality change and usual topological constraint changes. This…
We report a computational study of adsorption of aromatic radicals onto graphene, with the aim of understanding the effect of covalent molecular functionalization on the magnetic and structural properties of graphene. Our results show that the adsorption of an aromatic radical like phenyl also functionalized with dono…
The growth-kinetics of [6,6]-phenyl C61-butyric acid methyl ester (PCBM) crystals, on two different length-scales, is shown to be controlled by the thickness of the polymer layer within a PCBM-polymer bilayer. Using a model amorphous polymer we present evidence, from in situ optical microscopy and grazing-incidence X-…
ABSTRACT In this study, a series of waterborne polyurethanes (WPUs) with different contents of long‐branched aliphatic chains were synthesized through variation of the amount of diol chain extender trimethylol propane monooleate (TMPM). The effects of the TMPM content on the adhesion properties of the WPUs were invest…
In this study, the effects of oxidized polypropylene, as a compatibilizer, and Nano-clay particles in improving the thermal properties of wood plastic composites are investigated. For this purpose, polypropylene polymer was oxidized in the vicinity of the air oxygen for 2 hours. Then, in order to produce the samples,…
Nanoecotoxicology strives to understand the processes and mechanisms by which engineered nanoparticles (ENP) may exert toxic effects on aquatic organisms. Detailed knowledge of the chemical reactions of nanoparticles in the media and of their interactions with organisms is required to understand these effects. The pro…
Two {Ni6} cluster-containing inorganic-organic hybrid compounds have been successfully synthesized in the presence of organic amine under hydrothermal conditions, and they were characterized by powder and single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, and IR spectroscopy. Structural…
Wet chemical reduction of metal ions, a common strategy for synthesizing metal nanoparticles, strongly depends on the electric potential of the metal, and its applications to late transition metal clusters have been limited to special cases. Here, we describe copper nanoclusters grown by synchrotron radiolysis in conc…
This paper describes the preparation of graphitic porous carbon spheres (GPCS) from spherical resorcinol/formaldehyde resin by Fe-catalysis at 900 °C.
Fluorescent <sc>l</sc> -histidine-stabilized Au NCs were successfully synthesized by a green one-pot process since <sc>l</sc> -histidine played dual roles as both a stabilizer and a reducing agent. Moreover, the prepared Au NCs were used as a novel fluorescent probe for selective sensing of ferric ions in bean sprouts.
In this investigation, double layer microwave absorbers are designed and developed with paired combination of 5 wt. %, 7 wt. %, 8 wt. %, and 10 wt. % expanded graphite-novolac phenolic resin (EG-NPR) composites, in the frequency range of 8.2–12.4 GHz. The thickness and compositional combination of the two layers const…
Electronic structures and magnetic properties of the U(4+) complexes (C5Me4H)3UNO, (C5Me4H)3UCl, (C5H5)3UCH3, and (C5H5)3UCl are investigated by quantum chemical calculations. On the basis of wave function calculations including spin-orbit (SO) interactions, all complexes have nondegenerate nonmagnetic ground states.…
The resistance of particleboards, made from wood, bamboo and rice husk, to fungi and termites was evaluated. Panels were composed of 100% wood (Eucalyptus grandis), 100% bamboo (Bambusa vulgaris), 100% rice husk (Oryza sativa), 50% wood and 50% bamboo; and 50% wood and 50% rice husk. Panels exposed to the decay the br…
Ultra-high-temperature composite materials HfB 2 -SiC containing 10, 15, and 20 vol % SiC were prepared by spark plasma sintering. The behavior of the samples prepared under long-term exposure to subsonic dissociated airstreams of a high-frequency induction plasmatron was studied. The total test time per sample was 35…
Our comprehensive study on ${\mathrm{EuFe}}_{2}{\mathrm{As}}_{2}$ reveals a dramatic reduction of magnetic detwinning fields compared to other $A{\mathrm{Fe}}_{2}{\mathrm{As}}_{2}$ ($A=\mathrm{Ba}$, Sr, Ca) iron pnictides by indirect magnetoelastic coupling of the ${\mathrm{Eu}}^{2+}$ ions. We find that only $\ensurem…
A simple and highly sensitive and selective hydrogen sulfide assay utilizing plasmonic nanoprobes is presented in this report. The assay employs the etching of silver in the Ag/Au core-shell nanoprisms, accompanied by surface plasmon resonance (SPR) signal depression and shift. Briefly, thin layers of gold are first c…
In this paper, we examine the conditions under which the nonlinear transport theory is inescapable, when a correlated quantum dot is symmetrically coupled to two leads submitted to temperature and voltage biases. By detailed numerical comparisons between nonlinear and linear currents, we show that the claimed nonlinea…
Aim is to assess the anti-biofilm property of tenorite nanoparticles and to study their suitability as a possible coating material for medical implants. Tenorite (CuO) nanoparticles were synthesized by the optimized thermal decomposition method and characterized using TEM, XRD, FTIR and UV-Vis analysis. Their influenc…
