At this work we synthesized electrospun titanium oxide (TiO2) and nitrogen-doped (N-doped TiO2) for producing hydrogen (H2) in the same time pollutant removal from waste water by photocatalytic oxidation at room contitions.We use isopropoxide (TiP)/polyvinylpyrrolidone (PVP) solution to prepare dispersed polymer nanofibers sol–gel processing electrospinning techniques. TiO2 is a very effective ...

The use of late nitrogen (N) fertilization (N application at late growth stages of wheat, e.g., booting, heading or anthesis) to improve baking quality of wheat has been questioned. Although it increases protein concentration, the beneficial effect on baking quality (bread loaf volume) needs to be clearly understood. Two pot experiments were conducted aiming to evaluate whether late N is effect...

Z. Naturforsch. 41 a, 1302-1306 (1986); received August 7, 1986 The microwave ground state spectra of tert.-butyl isocyanide, (CH3)3CNC, and phenyl isocyanide, C6H 5NC, have been measured by microwave Fourier transform spectroscopy in the region 5.0 to 8.0 GHz and analysed for nuclear quadrupole hyperfine splitting due to ‘*N. The nuclear quadrupole coupling constants are shown to be in accorda...

This paper demonstrates the engineering and tuning of Ising-type magnetic anisotropy in trigonal bipyramidal Co(II) complexes. Here, we predict that employing a ligand that forces a trigonal bipyramidal arrangement and has weak equatorial σ-donating atoms, increases (in absolute value) the negative zero field splitting parameter D. With these considerations in mind, we used a sulfur containing ...

An enamel fragment from the Border Cave 5 specimen was analysed with non-destructive ESR combined with laser ablation ICP-MS for uranium profiling. We obtained an age of 74+/-5 ka which fits exactly into the chronological framework that has been previously established for Border Cave by a variety of dating techniques. The result lays at rest the view that BC5 could be of Iron Age, as was implie...

Global Krylov subspace methods are the most efficient and robust methods to solve generalized coupled Sylvester matrix equation. In this paper, we propose the nested splitting conjugate gradient process for solving this equation. This method has inner and outer iterations, which employs the generalized conjugate gradient method as an inner iteration to approximate each outer iterate, while each...

Consider the linear system Ax=b where the coefficient matrix A is an M-matrix. In the present work, it is proved that the rate of convergence of the Gauss-Seidel method is faster than the mixed-type splitting and AOR (SOR) iterative methods for solving M-matrix linear systems. Furthermore, we improve the rate of convergence of the mixed-type splitting iterative method by applying a preconditio...
