چکیده

2-D NCS-bridged {3d-4d} molecule-based magnets, formed by reaction of [Mo(III)(NCS)(6)](3-) with either Ni(II) or Co(II) complexes, have been found to exhibit magnetic ordering with T(C) = 39 K for {Co(3)Mo(2)} while {Ni(3)Mo(2)} has a non-magnetic ground state as a result of exact compensation by the individual sub-lattices.

Effect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets

Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...

Synthesis, Structures, and Thermal and Magnetic Properties of New Coordination Polymers Based on Mn(II) and Ni(II) Thiocyanato Complexes with trans-1,2-Bis(4-pyridyl)ethylene as Ligand

Hydrothermal reaction of manganese(II) thiocyanate with trans-1,2-bis(4-pyridyl)ethylene (bpe) in water leads to the formation of the new ligand-rich 1 : 3 (ratio metal/ligand) compound [Mn(NCS)2(bpe)2·(bpe)] (1-Mn). In the crystal structure the manganese cations are octahedrally coordinated by two thiocyanato anions and four bpe ligands and are linked into layers by the bpe ligands. Reaction o...

Probabilistic Evaluation of Seismic Performance of RC Bridges in Iran

 Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...

OPTIMAL DESIGN OF TRUSS BRIDGES USING TEACHING-LEARNING-BASED OPTIMIZATION ALGORITHM

In this study, teaching-learning-based optimization (TLBO) algorithm is employed for the first time for optimization of real world truss bridges. The objective function considered is the weight of the structure subjected to design constraints including internal stress within bar elements and serviceability (deflection). Two examples demonstrate the effectiveness of TLBO algorithm in optimizatio...
