Thin films of tin sulfide/cadmium sulfide (SnS/CdS) were prepared bythermal evaporation method at room temperature on a glass substrate and then annealedat different temperature with the aim of optimizing the optical properties of the materialfor use in photovoltaic solar cell devices. The effect of annealing on optical propertiesof SnS/CdS film was studied in the temper...

In this study, a full-potential density functional theory was used to investigate the effects of Ti substitution by different cations. In both rutile and anatase, Ti atom was replaced by Ce, Au, Sn, Ag, Mo, Nb, Zr, and Y. Phase stability, electronic structure and formation energy of oxygen vacancy were compared for rutile and anatase. The results indicated that substitution of Ce and Zr increas...

Studying the effect of a magnetic field on oligonucleotide DNA can provide a novel DNA manipulation technique for potential application in bioengineering and medicine. In this work, the optical and electrochemical response of a 100 bases oligonucleotides DNA, cytosine-guanine (CG100), is investigated via exposure to different magnetic fields (250, 500, 750, and 1000 mT). As a result of the opti...

Single-crystal Ni~dmit!2 salts, ~Ph4P!@Ni~dmit!2#3 , ~Bu4N!2@Ni~dmit!2#7•2CH3CN, and ~Me3S!@Ni~dmit!2#2 , have been synthesized. All show semiconducting behavior in their temperature-dependent dc conductivities. Room-temperature polarized reflectance measurements have been made over the range between 100 and 32 000 cm ~12 meV–4 eV!. For light polarized along the Ni~dmit!2 stacking axis, all spe...

We reveal the unique and fundamental advantage of inerter-based elastic metamaterials by a comparative study among different configurations. When embedded inerter is connected to matrix material on both ends, metamaterial shows definite superiority in forming band gap ultra-low frequency - equivalently ultra-long wavelength regime, where unit cell size can be four or more orders magnitude small...

ZnO thin films were deposited by successive ionic layer adsorption and reaction (SILAR) method using a zinc nitrate and ammonium bath on glass substrates. The number of employed cycles were 50, 100 and 200. The films were studied by X-ray diffraction (XRD), optical absorption (UV–Vis) and m-Raman. Structural analysis by XRD shows that the as-deposited ZnO films have high-orientation along c-dir...

We present a novel model to describe conduction band of GaNxAs1−x (GaNAs). As well known, GaNAs shows exotic behavior such as large band gap bowing. Although there are various models to describe the conduction band of GaNAs, origin of the band gap bowing is still under debate. On the basis of perturbation theory, we show that the behavior of conduction band is mainly arising from intervalley mi...

Maria Olkkonen Terhi Mustonen Abstract — In this study, the effect of vibration on mobile-phone text legibility caused by walking was examined. Legibility was measured as reading performance and subjective task load when reading from a mobile-phone display while walking on a treadmill at 1.5 km/hour, 3 km/hour, and an individually defined speed (3.9 km/hour on average). Vibration was measured o...
