A particle jumping in an octahedron studied by QENS
نویسندگان
چکیده
We calculate the neutron incoherent scattering law due to a particle performing localized di!usional jumps in a con"ned environment of octahedral symmetry. An experimental realization for this model is provided by the fulleride Li 12 C 60 , where the Li ions di!use within the octahedral void determined by the surrounding C 60 spheres packed in a face centered cubic crystal structure. The results of a recent experiment performed on IN6 are brie#y discussed in the light of the presented model. ( 2000 Elsevier Science B.V. All rights reserved.

متن کاملBiosorption of styrene from synthetic wastewater by sugar cane waste(Bagass)
In this work, styrene removal from wastewater by using sugarcane waste (bagasse) as an adsorbent was studied. Equilibrium isotherms and kinetics were determined; the effects of bagasse particle size and concentration, solutions pH, and temperature on the biosorption of styrene were studied in batch experiments. Adsorption equilibrium data was successfully fitted to Langmuir isotherms (R2=0.986)...
متن کاملAn efficient approach for availability analysis through fuzzy differential equations and particle swarm optimization
This article formulates a new technique for behavior analysis of systems through fuzzy Kolmogorov's differential equations and Particle Swarm Optimization. For handling the uncertainty in data, differential equations have been formulated by Markov modeling of system in fuzzy environment. First solution of these derived fuzzy Kolmogorov's differential equations has been found by Runge-Kutta four...
متن کاملEvaluation of nitric oxide involvement in effect of lead on dependency to morphine in mice
In the present study, interactions between lead exposure with nitric oxide precursor (L-arginine) or nitric oxide synthase (NOS) inhibitor (L-NAME) on naloxone-induced jumping and diarrhea in morphine-dependent mice were examined. Chronic lead acetate (0.05%) exposure altered naloxone-induced jumping and diarrhea in mice. Jumping was decreased after 7 days and was unchanged 14 and 28 days after...
