Octafunctionalised dibenzochrysenes are prepared in order to study the liquid crystalline properties that have chiral and achiral peripheral aliphatic chains. The syntheses of dibenzochrysene derivatives are achieved by a conventional method that has been developed recently. The achiral derivatives that have long peri…
The X-ray absorption near edge structure (XANES) and X-ray excited optical luminescence (XEOL) of a set of photoluminescent rare earth (RE) (Tb, Ce) doped silicon oxide (SiOx) thin films, having compositions ranging from O-rich (32% Si) to Si-rich (36% Si), were analyzed at the Si and O K-edges. The results show that…
Polycrystalline Mo(3)Sb(7-x)Te(x) samples with nominal Te concentrations of x=0.0, 0.3, 1.0, 1.6 and 2.2 have been synthesized by a powder metallurgical route. High temperature thermoelectric properties measurements including thermopower (300-900 K), electrical resistivity (300-800 K) and thermal conductivity (300-100…
Abstract By studying chitosan interactions with poly(styrene sulfonate) anions, a procedure that yields chitosan‐based non‐stoichiometric polyelectrolyte complexes soluble in neutral media has been developed. The elaborated strategy of the complex formation depended on the peculiar order of mixing the polyelectrolyte…
Surface acoustic wave (SAW) propagation properties in relaxor-based 0.67Pb(Mg(13)Nb(23))O(3)-0.33PbTiO(3) (PMN-33%PT) ferroelectric single crystals poled along [111](c) has been analyzed theoretically. We found that the X-cut PMN-33%PT has lower phase velocity and higher electromechanical coupling coefficient compared…
We have grown SrTiO3 thin films by rf-sputtering and studied its photoluminescence (PL) property after postannealing treatments. While the as-grown film does not show any PL signal, visible frequency PL emissions are induced by high temperature (T>550 °C) annealing. When subsequent low-T (50 °C) and long term (…
Ferroelectricity has been induced in the quantum paraelectric AgTaO3 (AT) by Li+ substitution, as evidence by both the dielectric anomaly and the hysteretic loop of electrical displacement versus applied electric field. The transition temperature (Tc) of Li-doped AT was found to increase with increasing level of Li+ s…
The synthesis and mesomorphic properties of a systematic range of ortho difluoroterphenyls with a bulky terminal chain are detailed. The bulky terminal chain consists of either a tertiarybutyl group or a trimethylsilyl unit, each separated from the core by a short (dimethylene) chain, with the other terminal chain bei…

Deep UV detection using a single crystal diamond (SCD) substrate without a homoepitaxial layer has been demonstrated using a defect passivation treatment. Despite evidence of surface damage on the SCD, the treatments lead to highly effective photoconductive devices, displaying six-orders of discrimination between deep…
Fluorescence microscopy (FM) is one of the most important analytical tools in modern life sciences, sufficiently sensitive to allow observation of single molecules. Here we describe the first application of the FM technique for the detection of inorganic environmental pollutants-airborne asbestos fibers that can cause…
Abstract Dragline spider silk has been intensively studied for its superior qualities as a biomaterial. In previous studies, we made use of the baculovirus mediated expression system for the production of a recombinant Araneus diadematus spider silk dragline ADF4 protein and its self‐assembly into intricate fibers in…
The third-generation peptide-dendrimer B1 (AcES)8(BEA)4(K-Amb-Y)2BCD-NH2 (B=branching (S)-2,3-diaminopropanoic acid, K=branching lysine, Amb=4-aminomethyl-benzoic acid) is the first synthetic model for cobalamin-binding proteins and binds cobalamin strongly (K(a)=5.0 x 10(6) M(-1)) and rapidly (k(2)=346 M(-1) s(-1)) b…
Rapid ingrowth of blood vessels and low inflammatory response are considered major prerequisites for successful implantation of biomaterials in reconstructive surgery. Aim of the present study was to evaluate whether tissue-engineered porous polyethylene (PPE) implants providing extracellular matrix components (ECM) a…
The optical properties of bare and passivated ${\text{Zn}}_{n}{\text{Se}}_{n}$ $(n=1--13)$ clusters have been studied within the framework of time-dependent local density approximation. The atomic structure of the clusters has been obtained using projector augmented wave pseudopotential method, with generalized gradie…
An artificial neural network (ANN) is investigated as a tool for estimating rate coefficients for the collisional excitation of molecules. The performance of such a tool can be evaluated by testing it on a data set of collisionally induced transitions for which rate coefficients are already known: the network is train…

The photovoltaic effects of Nb-doped SrTiO 3 single crystals with different thicknesses were investigated under the illumination of ultraviolet pulsed lasers. The peak photovoltage increased and then decreased quickly with the decrease in crystal thickness, and a maximum photovoltage occurred for the 180 µm-thick crys…
We theoretically study the early-stage real-time dynamics of the interlayer $\ensuremath{\sigma}$-bond formation by visible-light irradiation of graphite crystal. An electron-hole pair, generated as an interlayer charge-transfer excitation in the visible region, mostly dissipates away into the two-dimensional semimeta…
