Reorientation kinetics of superparamagnetic nanostructured rods

Self-Organization Kinetics of Mesoporous Nanostructured Particles

Spray drying a mixture of silica and polystyrene latex (PSL) colloids above the decomposition temperature of PSL results in the formation of porous silica particles. By appropriate selection of the experimental conditions, such as the use of a tubular temperature, the weight fraction of colloids, and the flow rate of carrier gas, the resulting silica particles contain organized pores with a hex...

Reaction kinetics of nanostructured SOFC cathodes

Kinetics of exocytosis is faster in cones than in rods.

Cone-driven responses of second-order retinal neurons are considerably faster than rod-driven responses. We examined whether differences in the kinetics of synaptic transmitter release from rods and cones may contribute to differences in postsynaptic response kinetics. Exocytosis from rods and cones was triggered by membrane depolarization and monitored in two ways: (1) by measuring EPSCs evoke...

A refined theory of magnetoelastic buckling matches experiments with ferromagnetic and superparamagnetic rods.

In its simplest form the magnetoelastic buckling instability refers to the sudden bending transition of an elastic rod experiencing a uniform induction field applied at a normal angle with respect to its long axis. This fundamental physics phenomenon was initially documented in 1968, and, surprisingly, despite many refinements, a gap has always remained between the observations and the theoreti...

Kinetics of photocatalytic degradation of methylene blue on nanostructured TiO2 coatings created by sol-gel process

Sol-gel process was chosen to produce a photocatalytic film to degrade methylene blue. In order to study structural and morphological properties of the coatings, a base sol of TTIP, I-PrOH, and DEA was prepared. Then with addition of 45g/L PEG 2000, 30g/L TiO2 and 15g/L PEG 2000 + 30g/L TiO2, to the base sol, three other sols were produced. The results of this study indica...
