A novel dual-band frequency selective surface (FSS) with composite element is presented, in which each periodic cell consists of a left-handed structure unit on the front side of the dielectric slab and a capacitive grid on its back side. As a result, a dual-band FSS operated over Ku-band (12 GHz) and Ka-band (35 GHz)…
A novel Cu(II)-MOF {[Cu4(TTTMB)4(NO3)4(H2O)5]·(NO3)2·(I3)2·H2O}n containing polyiodide I3− was obtained through crystal to crystal transformation by immersing a CdII complex {[Cd3(TTTMB)4I2]·I4}n in an aqueous solution of Cu(NO3)2. There are two kinds of I3− arranged as infinite zigzag ⋯I3−⋯I3− chains between the laye…
We report the behavior of one-dimensional polythiophene-based nanofibers in solutions passing through the nanopores under a flow field. Under a strong flow field, a fiber-to-cluster transition can be observed when the nanofiber solution concentration is above a critical value. The Zimm time and the passing time of the…
A facile method of solution combustion was used to synthesize a new solid solution Bi(2)Ce(2)O(7). The structure was determined from powder X-ray diffraction (PXRD) and found to crystallize in the space group Fm3m with cell parameter a = 5.46936(9) Å. The particle sizes varied from 5 to 6 nm. The degradation of cation…
Crystals of phosphopantetheine adenylyltransferase (PPAT) from Mycobacterium tuberculosis in the apo form and in complexes with coenzyme A (PPAT/CoA) and dephosphocoenzyme A (PPAT/dPCoA) were grown in microgravity by the capillary counter-diffusion method. The structures of PPAT Mt in the apo form and in complexes wit…
ZnO replicas with photonic structures were fabricated from Papilio paris butterfly wing scales and their tunable optical properties were studied. Through modification of the fabrication method, the reticular porous network structure was successfully replicated from dark black (DB) wing scales. The DB wing scale replic…
New luminescent oxynitrides based on the apatite structure doped with Eu2+ and Ce3+ have been prepared by ammonolysis of oxysilicate or oxygermanate precursors. The host compounds have the general formula La10−xSrx(Si/Ge)6O27−x/2−3y/2Ny. When doped with divalent europium or trivalent cerium they present blue, green, y…
Crystallisation of glasses based on the diopside-anorthite eutectic system, containing increased amount (10- 50 wt.%) of wollastonite based on granite quarries waste, was investigated for the preparation of cheap technical glass-ceramic materials. Granite quarries waste consisted of about 52 wt.% of the batch constitu…

The complexation of Fe(SO(3)CF(3))(2) to the series of fluoro α-substituted tris-(2-aminomethylpyridyl)amine tripods F(1-3)TPA yields the triflato F(1-3)TPAFe(SO(3)CF(3))(2) complexes which have firstly been characterized in solution. As expected, bis-acetonitrile charged species are present in CH(3)CN, and neutral bi…
Through an organometallic approach, ultrathin SnO(x)Fe(y)S(z) plates with ~2 nm single layer-thicknesses were obtained and their graphene composites showed very promising discharge capacities of up to 736 mA h g(-1) and excellent stabilities as anode materials in lithium ion batteries.
Current tissue engineering technologies involve the seeding of cells on porous scaffolds, within which the cells can proliferate and differentiate, when cultured in bioreactors. The flow of culture media through the scaffolds generates stresses that are important for both cell differentiation and cell growth. A recent…
Luminescent-conjugated oligo- and polythiophenes (LCOs and LCPs) are valuable tools for optical imaging of a plethora of protein aggregates associated with amyloidoses. Here, we describe the utilization of an anionic pentameric LCO, p-FTAA, for staining of protein aggregates in a variety of platforms, including in vit…
The increasing use of non-linear loads in electrical installations has exacerbated the problems of harmonic distortion in industrial and commercial electrical systems. In the UK the current practice to determine the cable size for an electric circuit is to use BS7671. However, previously the 16th edition IEE Wiring Re…
Deformation microstructures developed in cold-rolled ultra low carbon (ULC) steel as well as those in low carbon (LC) steel have been investigated by using TEM and SEM-EBSD techniques. Particular attention has been paid to the effect of solute carbon on the development of those microstructures. Dislocation structures…
L1 0 -FeNi films were grown by alternate monatomic layer deposition on Au–Cu–Ni buffer layers at several substrate temperatures ( T s ), and the relation between the uniaxial magnetic anisotropy energy ( K u ) and the long-range chemical order parameter ( S ) was investigated. A large K u of (7.0 ±0.2) × 10 6 erg/cm 3…
The paper presents a study on the phenomenon of wetting of minerals in the two cases where a wetted solid is placed on a liquid surface and a liquid is on a flat solid surface. Knowledge of physi- cal and chemical processes occurring between a liquid and solid is an important issue. Contact angle measurement and deter…
Iron-coke having various amount of M.Fe were produced in laboratory scale and the influence of M.Fe content in Iron-coke on reaction behavior under the condition simulating blast furnace has been investigated. Cold strength of Iron-coke products was decreased with an increase of mixing ratio of iron ore mostly due to…
Calcium titanate particles in the nanometer size regime have been successfully synthesized by mechanochemical method using green chemistry approach.

Fusion of fluorescent probes to axonally transported proteins represents an established approach that enables live imaging of axonal transport. In this approach, in vivo examination of fluorescent particle dynamics provides information about the length, directionality, and the velocity by which axonally transported pr…
