The output of a piezoelectric nanogenerator based on ZnO nanowire is largely affected by the shape of nanowire. In order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. This paper presents the various behavior of ...

Wafer and die level uniformity effects in Deep Reactive Ion Etching (DRIE) are quantitatively modeled and characterized. A two-level etching model has been developed to predict non-uniformities in high-speed rotating microstructures. The separation of wafer level and die level effects is achieved by sequentially etching wafers with uniformly distributed holes. The wafer level loadings range fro...

ABSTRACT We use H i absorption along the lines-of-sight to Q0107 quasar triplet in order model potential disc and outflow structures circumgalactic medium of intervening galaxies at z ? 1, as well intergalactic on scales up a few virial radii. consider sample twelve isolated field with position angles inclinations measured from HST imaging redshifts our spectroscopic surveys, alongside 27 detec...

At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...

We show that the set of conical points of a rational function of the Riemann sphere supports at most one conformal measure. We then study the problem of existence of such measures and their ergodic properties by constructing Markov partitions on increasing subsets of sets of conical points and by applying ideas of the thermodynamic formalism. 1 Introduction. In this paper we recall from U2] the...

die erlebnislyrik umfasst die gedichte, in denen es um die erinnerung eines lyrischen ichs an ein geschehen geht, wobei mit dem gedichtschreiben ein erinnerungsvorgang in gang gesetzt wird, der einen bezug zwischen dem erlebenden ich und dem geschehen schafft und damit ein unmittelbares erleben erzeugt. die speziellen mittel der lyrik wie reim, rhythmik, klang, melodie, wiederholung, bildsprach...
