Solvent-tuned magnetic behaviors of manganese(III) corroles

Solvent-tuned hierarchical porosity in nitrocellulose aerogels.

We describe the simple preparation of nitrocellulose gels and high surface area (300 + m(2) g(-1)) aerogels and their hierarchical pore structures. The solvent in which the gels form greatly influences the pore geometry and size distribution of the gels in both the macro- and mesopore domains.

Anisotropy-Tuned Magnetic Order in Pyrochlore Iridates.

The magnetic behavior of polycrystalline samples of Er(2)Ir(2)O(7) and Tb(2)Ir(2)O(7) pyrochlores is studied by magnetization measurements and neutron diffraction. Both compounds undergo a magnetic transition at 140 and 130 K, respectively, associated with an ordering of the Ir sublattice, signaled by thermomagnetic hysteresis. In Tb(2)Ir(2)O(7), we show that the Ir molecular field leads the Tb...

Meso-meso linked corroles.

The cascade reaction of sterically hindered dipyrromethanes and formaldehyde furnished meso(10)-meso(10') linked corroles--a new type of porphyrinoid--compounds with interesting photophysical properties.

Tuned Parameters of PID for Optimization of Losses in Magnetic Levitation System

In this paper a new method is proposed for determining PID controller parameters in order to decrease losses in levitation system of magnetic trains. It is assumed that this system is a hybrid system and it consists of electric and permanent magnet. For optimization of losses initially AC losses of magnetic levitation system are calculated. Linear model of levitation system as well as modeling ...
