A new series of heterometallic wheels, isolated as [Fe18M6(piv)12(Htea)18(tea)6(N3)6]·n(solvent) (MIII = Y (1a, 1b), Gd (2a, 2b), and Dy (3a, 3b); Hpiv pivalic acid, H3tea triethanolamine), forms by the reaction trinuclear μ3-oxo-linked or hexanuclear μ-OH-linked Fe(III) pivalate clusters with rare earth nitrates, H3tea, azide ligands in MeOH/MeCN EtOH/MeCN media under ultrasonic irradiation.

Abstract Robotic splicing of steel arches is a challenging task that necessary to realize the grasping and docking in limited space. Steel often have mass more than 200 kg length 4 m. Owing large volume high requirements for accurately positioning splicing, it difficult general manipulator meet stiffness requirements. To enhance structural arch manipulator, single-degree-of-freedom (DOF) closed...

Abstract This study is aimed to determine collision integrals for atoms interacting according the m-6-8 and Hulburt–Hirschfelder potentials analyze differences between potentials. The precision of four significant digits was reached at all tested temperatures, high-temperature applications, six were calculated. proposed method on Lennard-Jones potential found excellently agree with recent high-...
