A series of ditopic ligands incorporating two 2,2′:6′,2″-terpyridine (tpy) metal-binding domains linked to a central naphthalenediyl core by ethyleneoxy chains of various lengths have been prepared and their iron(II) complexes prepared. The major thermodynamic products of complexation are ferracycles of [1 + 1], [2 +…
A SiC nanowire can be transformed into a carbon nanotube or a SiC-C core-sheath nanowire owing to Joule heating by applying a current typically on the order of 10 muA, and the transformation can be observed in situ by means of transmission electron microscopy.

Polymer matrix composites (PMC), often referred to as fiber reinforced plastics (FRP), consist of fiber reinforcement (E-glass, S2-glass, aramid, carbon, or natural fibers) and polymer matrix/resin (polyester, vinyl ester, polyurethane, phenolic, and epoxies). Eglass/polyester and E-glass/vinyl ester composites are ex…
A novel strategy to control the formation of amphiphilic brushes from metallo-supramolecular block copolymers is described. The investigated copolymer consists of a polystyrene block linked to a poly(ethylene oxide) one via a charged bis-terpyridine ruthenium(II) complex (PS-[Ru]-PEO). The initial hexafluorophosphate…
In this work, single crystalline, defect free metal oxide (NiO) nanoparticle with diameter ~40nm was synthesized by only two steps soft chemical synthesis route. The crystalline nature of the sample was studied by X-Ray Diffraction method. TEM and HRTEM analysis was done to examine the morphology of the as prepared sa…
First-principles calculations are used to predict a plausible reaction pathway for the methane oxidation reaction. In turn, this pathway is used to obtain trends in methane oxidation activity at solid oxide fuel cell SOFC anode materials. Reaction energetics and barriers for the elementary reaction steps on both the c…
This paper describes the application of Attenuated Total Reflection Fourier Transform Infra-red Spectroscopy (ATRFTIR) together with Scanning Probe Microscopy (atomic force microscopy and micro-thermal analysis) on accelerated aged and archival parchment samples. Damage assessment by ATR-FTIR of collagen, the main con…
Dark-brownish, euhedral crystals of an “allanite-like” mineral occur in a hematite-impregnated Mn-silicate rock at Kesebol, Västra Götaland, Sweden, associated with gasparite-(Ce), chernovite- (Y), rhodonite, andradite, manganoan calcite, and quartz. A structural study was carried out on single crystals-untreated, hea…
Cells display on the outer surface of the plasma membrane a large number of protein thiols that can be reversibly labelled with suitably designed Gd(III)-based contrast agents for cell tracking by MRI.
A stable short-range crystalline structure is observed in colloidal systems with competing short-range attractions and long-range repulsions. We term these structures "microcrystalline gels" as the microcrystals are embedded in a dense disordered network.
In this work, we aim to study the hydrogen adsorption in several kinds of carbon nanotubes grown under different process conditions and to correlate the findings with the morphological microstructure and physical properties of these materials. The growth conditions and the behaviour with respect to hydrogen interactio…
Between 2003-2007, abomasa of 91 European bison (Bison bonasus), 4 red deer (Cervus elaphus) and 2 roe deer (Capreolus capreolus) shot in the Białowieza Primeval Forest (Poland) were examined for worms presence. All the animals examined were infected with nematodes A. sidemi with an exception of one bison, that was sh…
This work described the photoluminescent (PL) and thermal stability properties of -doped phosphors, with the composition that can be excitable under vacuum UV (VUV) light. The concentration of Tb as a fraction of that of Ca was varied from . The sample with had the highest emission intensity. The obtained activation e…
Three series of waterborne polyurethane (WBPU)/carbon nanotube (CNT) nanocomposites were prepared, and their morphology and properties with various 2,2-dimethylol propionic acid (DMPA) and CNT contents were investigated. The CNTs were homogeneously dispersed up to the optimum content in WBPU/CNT nanocomposite films. T…
Prussian blue nanoparticles (PB NPs), stabilized for the first time by the pi-conjugated polymer poly(4-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2yl-methoxy-1-butanesulfonic acid, potassium salt) (PEDOT-S), demonstrated a novel multiple-color pH-sensing function with a redox reaction based on the electronic interaction be…
A novel cobalt compound [Co(9)(HL)(4)(L)(4)Cl(2)] x (EtOH)(2)(H(2)O)(2) (H(3)L = (E)-2-2((1,3-dihydroxy-2-methylpropan-2-ylimino)methyl) phenol) has been solvothermally synthesized and structurally characterized. The compound crystallised in the space group C2/c with a = 32.624(2) A, b = 9.4814(4) A, c = 33.395(2) A,…
TiMn alloy was prepared by mechanical alloying and subsequently consolidated by spark plasma sintering (SPS) technique for exploration of biomedical applications. The microstructures, mechanical properties and cytotoxicity of the TiMn alloys were investigated in comparison with the pure Ti and Mn metals. Ti8Mn and Ti1…
OFETs built from extended TTF derivatives containing N-methylpyrrole, furan, thiophene and benzene with meta or para linkages as spacers are presented. The aromatic spacer plays a crucial role in the characteristics and stability of the OFETs. The less conjugated derivative with a meta-benzene moiety as spacer has the…
Pure and Gd 3+ ‐doped titanate nanotubes (TNTs) materials were synthesized by a hydrothermal method. Their morphology, optical properties, thermal stability, and magnetic properties were characterized by X‐ray diffraction (XRD), transmission electron microscope (TEM), UV‐Vis spectroscopy, thermal analysis, and magneti…
