The incorporation of guanidinium ions (Hgua+) in Cu(II)–M(V) systems results in the formation of two isostructural coordination polymers (Hgua)Cu(II)[M(V)(CN)8], M = W (1); Mo (2), which reveal a double-layered structure separated by guanidinium ions. The magnetic measurements reveal long range magnetic ordering with…
The photoluminescence of four polyoxoniobates [Nb6O19]8-, [Nb10O28]6-, [Ti2Nb8O28]8- and [H2Si4Nb16O56]14- was observed, and its origin was revealed in the view of molecular orbital by means of the computational method. The photoluminescence is originated from singlet transitions, and the calculated values agree well…
A new method for triggering the burst liberation of encapsulated sub-micron particles from carrier particles using embedded microorganisms has been developed. Triggering mechanisms such as those based on chemical, light, thermal, or magnetic stimuli are known, but man-made particles are not yet able to replicate the c…
Transparent conductive Ti, Al codoped ZnO (TAZO) films were prepared on glass substrate by three-target magnetron sputtering system in this work. The glass substrate was heated to 200 °C, and the working pressure in the chamber was at 5×10 -2 Torr. In the process of sputtering, pure Ti target was bombarded by direct c…

The dielectric, ferroelectric, and piezoelectric properties of ceramics from the Pb0.88Sr0.12 Zr0.54Ti0.44Sb0.02O3 system were investigated as a function of annealing time after being prepared via the solid-state method. Following the annealing process, a shift in the ferroelectric to paraelectric transition temperatu…
We report the structural characterization of homoepitaxial (001) SrTiO3 films grown by pulsed laser deposition on single crystal (001) SrTiO3 substrates. X-ray diffraction θ−2θ scan and φ scan were used to study the lattice constants and crystal quality of the SrTiO3 films. Lattice expansion in the c-axis from the bul…
The electrical, magnetic and magnetocaloric properties of Sm0.6−xEuxSr0.4MnO3 were investigated for x = 0, 0.2 and 0.4. The Curie temperature decreases from 114 K to 62 K and Metal-Insulator transition temperature also decreases with increasing Eu content. A low temperature maximum is found within the long range ferro…
The AZX (X = calcium) series of magnesium alloys have recently been developed as lightweight incombustible alloys for use in automotive and railway vehicles. However, magnesium alloys containing Ca show inferior plastic deformation and poor formability. The tensile properties of rolled and annealed samples of Mg-3Al-1…
A new type of metal di-porphyrin dyes have been designed and characterized by density functional calculations.Structural optimizations and subsequent frequency calculations for the isolated dyes were performed using the B3LYP hybrid functional in combination with the all-electron 6-31G(d) basis set.Bulk solvent effect…
Paper presents both methods of the most advanced thermal annealing as well as available methods of testing the magnetoelastic properties of soft magnetic materials for technical applications. Selected features and conditions important for annealing of ring-shaped cores made of the magnetoelastic amorphous ribbons are…
The problem of debris bed coolability is important for nuclear power plant severe accident management strategies which employ corium melt fragmentation in a deep pool of water as a means to termina ...
Metallurgical and Materials Applications of Shock-Wave and High-Strain-Rate Phenomena, with K. P. Staudhammer and M. A. Meyers (eds.), Elsevier Science Publishers, Amsterdam, 932 pp.
The aim behind the development of particle design techniques is to alter the physicochemical, micromeritics and biopharmaceutical properties of the drug. Melt sonocrystallization a novel technique of particle engineering to enhance dissolution of hydrophobic and other drugs having solubility problem and to study its e…
In paper and board industry there is a strong need for a radically more resource-efficient production technologies, which would also enable the manufacture of sustainable and value- added fibre products. In this paper we introduce foam forming method, where foam is used as a transporting media of furnishes. The techno…
Bacterial cellulose (BC), produced by acetic acid bacteria Gluconacetobacter xylinus, is ideal for delivery and related biomedical functions. It is FDA approved for wound dressings and internal applications, non-toxic to endothelial cells and has little effect on blood profiles. Conjugation of therapeutics to BC can b…

ダイヤモンドライクカーボン(DLC）は，sp2炭素・sp3炭素・水素からなるアモルファス炭素同素体である．本報では，著者らがこれまで行ってきたX線光電子分光法（XPS）によるDLC薄膜の表面化学構造解析について解説する．DLC薄膜のC 1sスペクトルは，Gauss関数を重畳したDoniach-Šunjic関数によって解析され，sp2/sp3炭素ならびに炭素‐炭素/炭素‐水素結合の差異を説明する4成分に波形分離された．本解析は，高分解弾性反跳検出（ERD）法による実水素量分布に対応した．他方，DLC表面の酸素官能基分析のための，簡単な数学的処理を加味した修正気相化学誘導体化(GCD）法も解説する．本法は解析を複雑にする副反応を考慮し…
In this paper, we focused on BTL (Biomass-to-Liquid) fuel for trucks which is synthesized from woody biomass feedstock, and discussed the alternative potential of BTL for the purpose of mitigation of CO2 emission in a transportation sector. Here, we estimated the specific CO2 emission of BTL fuel and the energy intens…
