Horizontal segregation of mono-layer granules coordinated by vertical motion

We experimentally investigate the segregation of a binary mixture of spherical beads confined between two horizontal vertically vibrating plates. The two kinds of beads are of equal diameter and mass but have different restitution coefficients. Segregation occurs in particular ranges of vibration amplitude and frequency. We find that the collisions between beads at an angle to the horizontal plane induce an effective horizontal repulsive force. When one or both bead types bounce up and down in synchronization, the effective repulsive force between the two types of beads is likely to be larger than that found within a single bead type, resulting in the mixture segregating. Non-horizontal collisions also play a role in stabilizing the segregation state by transferring the horizontal kinetic energy back into vertical motion

Immobilization of lactate dehydrogenase within multiwalled carbon nanotube-chitos anhanocompo site for application to lactate biosensors

A composite of multiwalled carbon nanotubes-chitosan (MWCNT-CHIT) was used as a matrix for entrapment of lactate dehydrogenase (LDH) onto a glassy carbon electrode in order to fabricate amperometric biosensor. The homogeneity of the resulting multiwalled carbon nanotubes-chitosan-lactate dehydrogenase (MWCNT-CHIT-LDH) nanobiocomposite film was investigated by atomic force microscopy (AFM). It shows that the enzyme is homogeneously immobilized within MWCNT-CHIT-LDH. The inclusion of MWCNT within MWCNT-CHIT-LDH exhibits the abilities to raise the current responses, to decrease the electrooxidation potential of P-nicotinamide adenine dinucleotide, reduced form (NADH), and to prevent the electrode surface fouling. The influence of several experimental parameters such as applied potential, solution pH value, NAD(+) concentration, and enzyme loading was explored to optimize the electroanalytical performance of the biosensor. The optimized biosensor for the determination of lactate shows a sensitivity of 0.0083 AM(-1) cm(-2) and a response time of about 3 s. The proposed biosensor retained 65% of its original response after 7 days. (C) 2007 Elsevier B.V. All rights reserved
