The ultrafast photoinjection and subsequent relaxation steps of the indoline dye D149 were investigated in detail for a mesoporous electrodeposited ZnO thin film and compared with experiments on sintered TiO(2) and ZrO(2) thin films, all in contact with air, using pump-supercontinuum probe (PSCP) transient absorption spectroscopy in the range 370-770 nm. D149 efficiently injects electrons into ...

the multiple traveling salesman problem (mtsp) is a generalization of the famous traveling salesman problem (tsp), where more than one salesman is used in the solution. although the mtsp is a typical kind of computationally complex combinatorial optimization problem, it can be extended to a wide variety of routing problems. this paper presents an efficient and evolutionary optimization algorith...
The early stage of molecular excitonics and its quantum-kinetic dynamics in the multiband, bitubular cyanine dye aggregate C(8)O(3) at room temperature are revealed by employing two-dimensional (2D) coherent electronic spectroscopy in the visible spectral region. The sub-20 fs measurements provide a direct look into the details of elementary electronic couplings by spreading spectroscopic trans...
Terbium oxide doped tetraborate glasses were prepared from the reaction of Tb2O3 and Na2B4O7 .10 H2O on reagent grade. At first, the base borate glass of Na2B4O7 was prepared by melting dehydrated borax at 1000 ˚C for 30 min and then the obtained base glass was crushed and powdered. Appropriate amounts of Tb2O3 (5-20 mol %) and Na2B4O7 powdered glass were mixed and melted at 1200 ˚C for 15 min....
background: the aim of the present study was application of haemoglobin absorption spectroscopy as a distinguishing tool for identification of two haemoglobin types-hba and hbs. material and methods: millimolar absorptivities of normal adult haemoglobin (hba) and sickle cell haemoglobin (hbs) were monitored at ph values of 7.2 and 5.0, within the ultra violet and visible spectral range (250-650...

The present work comprises the synthesis of one series of diarylmethane dyes containing one or more terminal methoxy substituents together with a variable tertiary amino group. The electronic absorption spectra of the dyes have been determined. As the conjugation of the terminal nitrogen atom improves in the sequence NMez > Kairoline > Julolidine, a progressive hypsochromic shift is observed
The influence of urea as an additive in dyeing of wool with madder was evaluated in this work. A different concentration of urea was applied on wool yarns before, during and after dyeing of samples. The treated samples were tested for dye absorption at different time, wicking, sinking, wash and light fastness and surface morphology by scanning electronic microscope. The results show that urea i...
