Three homochiral layered complexes, [Cu3(R-chea)2(N3)6]n (1), [Cu3(S-chea)2(N3)6]n (2) (chea = 1-cyclohexylethylamine) and [Cu3(S-phpa)2(N3)6]n (3) (phpa = 1-phenylpropylamine), and three novel cluster-based coordination polymers, [Cu6(1,2-pn)4(N3)12]n (4) (1,2-pn = 1,2-diaminopropane), [[Cu8(en)4(N3)16] x H2O]n (5) (…
A gadolinium-doped ceria (GDC)/scandia-stabilized zirconia (ScSZ) bilayer electrolyte on a microtubular (LSM) support was prepared via extrusion of a microtubular cathode support and subsequent surface coatings with electrolyte and anode slurries. The GDC/ScSZ bilayer electrolyte was obtained on the LSM support using…
A novel series of second-order NLO chromophores containing pyrrole as an auxiliary electron donor was synthesized via Knoevenagel reactions between 5-aminated N-methylpyrrole-2-carbaldehydes and different electron-accepting groups, i.e., malononitrile, picolinium tosylate and 2-dicyanomethylene-3-cyano-4,5,5-trimethyl…
In this study Ag+ adsorption on Na+-rich montmorillonite (MMT) type Wyoming was studied. Adsorption data were fitted with several common isotherms but the best regression parameters were obtained for Langmuir model. It indicates that Ag+ was adsorbed on the MMT surface forming a monolayer. By adsorption of small amoun…
The performance of solid oxide cells (SOCs) is highly dependent on triple phase boundaries (TPBs). Therefore, detailed TPB characterization is crucial for their further development. We demonstrate that it is possible to prepare a thick transmission electron microscopy (TEM) lamella of the interface between the dense c…
Using additives is one of more recent and special methods to obtain a desirable polymorph. However, for pharmaceuticals, additives are usually limited to structurally related organic compounds. In this study, we have shown the potential of using a salt additive to induce crystallization of the metastable polymorph V o…
Polypropylene/high-density polyethylene (PP/HDPE) blends and their nanocomposites are melt compounded using twin-screw extruder. The as-extruded samples are then batch foamed with supercritical carbon dioxide. It is demonstrated that the blend with a viscosity ratio close to unity produces a microcellular foam with ve…
Transdermal route is an evolving panorama in novel drug deliverance and with oral route they proffer immense potential. Most recently there is hastening in approaches for delivering bioactives via these routes, amongst them revolution has been made by dendrimers. Encapsulation and conjugation of bioactives with these…
Lamellar structures of alternating sheets of crystalline V2O5 (shcherbinaite) and cations from certain imidazolium-based ionic liquids (IL) (e.g. 1-ethyl-3-methyl-imidazolium tetrafluoroborate) were obtained starting from VOCl3. Surprisingly, growth along the [100] direction of shcherbinaite is suppressed due to the i…
Thermodynamic calculations of three binary Ti-based alloys: Ti-Al, Ti-Fe, and Al-Fe, as well as ternary alloy Ti-Al-Fe, is shown in this paper. Thermodynamic calculations involved thermodynamic determination of activities, coefficient of activities, partial and integral values for enthalpies and Gibbs energies of mixi…
The jellium sphere model of a volume of electrons, counterbalanced by a positive charge throughout the sphere, leads to an energy level sequence corresponding to special stabilities of bare post-transition element clusters with 20 valence electrons such as the known P4 and clusters with 40 valence electrons such as th…
Dy3+-doped selenide glasses and their optical fibers in the Ge-Ga-Sb-Se glass-forming system were fabricated and their mid infrared (MIR) emission (2.5-5 μm) characteristics were analyzed. Optimum concentration for 3 μm emission band was determined as 0.02 mol% due to cross relaxation between Dy3+ ions. Sensitizers su…

The effect of initial grain size on dynamically recrystallized grain size (DRX grain size) is examined in AZ31 magnesium alloy with four kinds of initial grain sizes. When the average grain size after the high-temperature compression test is plotted against Zenner-Hollomon parameter (Z-parameter), initial grain size d…
We report a field effect transistor (FET) based on a network of single-walled carbon nanotubes (SWCNTs) which can selectively detect human immunoglobulin G (HIgG). HIgG antibodies, which are strongly adsorbed onto the walls of the SWCNTs, are the basic elements of the recognition layer. The non-specific binding of pro…
We report event-driven molecular dynamics simulations of the irreversible gelation of hard ellipsoids of revolution containing several associating groups, characterizing how the cluster size distribution evolves as a function of the extent of reaction, both below and above the gel point. We find that over a very large…
A simple synthesis of homogeneously sized, ordered mesoporous silica nanorods (SBA-15), spanning about 10 porous channels in width and ranging from 300 to 600 nm in length is reported.
The time‐resolved two‐photon photoemission technique (TR‐2PPE) has been applied to study static and dynamic properties of localized surface plasmons (LSP) in silver nanoparticles. Laterally, integrated measurements show the difference between LSP excitation and nonresonant single electron‐hole pair creation. Studies b…
A pigment array has been constructed within a paracrystalline amyloid nanotube and Förster energy transfer along the nanotube surface has been demonstrated to self-assembled acceptor dyes.
To develop suitable sealants for planar anode-supported intermediate temperature solid oxide fuel cells ͑IT-SOFC͒ operating at around 800°C, several glass-ceramic compositions based on the RO-Al 2 O 3 -SiO 2 ͑R = Ba,Ca͒ system have been prepared and investigated.Thermal, chemical, and electrical properties of the glas…
