“…Our magnetic measurement shows that the anisotropy field of SmCo 7Kx M x compounds increases with increasing content of M. The similar behavior have been found in Sm-Co 2:17 phase when part of Co is replace by Mn or Zr [31,32]. Recently, Zr, Cu and Ti have been used as effective doping elements to improve the magnetic properties of the 1:7 type phase [33][34][35][36][37][38][39][40].…”

“…A corner-pumped method for high-power quasi-three-level lasers has been reported in the recent years [8][9][10][11][12]. We have realized CW operation with 1 kW 1030 nm output power and 42.8% slope efficiency from a corner-pumped composite Yb:YAG/YAG slab laser [9].…”

A corner-pumped type is a new pumping type in the diode-pumped solid-state lasers, which has the advantages of high pump efficiency and favorable pump uniformity. A corner-pumped Nd:YAG/YAG composite slab continuous-wave 1319 nm/1338 nm dual-wavelength laser is first demonstrated in this paper. When the cavity length is 25 mm, the maximal output power is up to 7.62 W with a slope efficiency of 16.6% and an optical-to-optical conversion efficiency of 17%. The corresponding spectral line widths of 1319 nm laser and 1338 nm laser are 0.11 and 0.1 nm, respectively. The short-term instability of the output power is better than 1% when the pumping power is 39.5 W. The experimental results show that a corner-pumped type is a kind of feasible schedules in the design of diode-pumped solid-state 1.3 μm lasers with low or medium output powers.

“…Heating rate applied in the experiments was sufficiently fast (20 • C/min) in order to hinder formation of molybdenum nitride in the temperature range of 20-600 • C which is important for the HDS catalytic reaction. (Formation of ␥-Mo 2 N usually proceeds at substantially lower heating rates (0.6-2 • C/min [42].) Despite the limitation, the TPR experiments were carried out up to 1000 • C, in order to investigate the changes in the state of the catalyst components.…”

a b s t r a c tTiAlZr mixed oxides, synthesized using sol-gel method, were characterized and used as supports of hydrodesulfurization catalysts (12 wt% Mo) prepared by impregnation either with molybdenum heteropolyacid H 3 PMo 12 O 40 or its cobalt salt Co 1.5 PMo 12 O 40 . Structure, morphology and textural properties of oxides and catalysts were characterized using X-ray powder diffraction (XRD), Raman spectroscopy, Nitrogen adsorption porosimetry, TEM-EDS, temperature-programmed desorption (TPD) and temperature-programmed reduction (TPR) techniques. Activity of the catalytic systems was tested in thiophene hydrodesulfurization (HDS).No formation of a new oxide phase was revealed in the synthesized mixed materials. However the effect of separated oxides on the structure of ternary oxides was observed. Maximum in HDS activity of Mo containing samples was determined by optimum content of alumina in the mixed oxides. Incorporation of cobalt into the heteropolyacid increased the HDS activity about two times and masked the effect of the support composition.
