A novel modified Ni-ZSM-5 nanozeolite was fabricated via an organic template-free hydrothermal route. The average particle size of Ni-ZSM-5 nanozeolite was calculated to be 85 nm by scanning electronic microscopy. Then, Carbon paste electrode (CPE) was modified by Ni-ZSM-5 nanozeolite and Ni2+ ions were then incorporated to the nanozeolite matrix. Electrochemical behavior of this electrode was ...

Catalytic nanomotors with silica microbead heads and TiO(2) arms are systematically designed by dynamic shadowing growth. The swimming trajectories are fine tuned by altering the arm length and orientation exploiting geometry-dependent hydrodynamic interactions at low Reynolds number. The curvature, angular frequency, and radius of curvature of the trajectories change as a function of arm lengt...

In this study of catalytic microfluidic reactors we show that, when optimally structured, these reactors share underlying scaling properties. The scaling is predicted theoretically and verified numerically. Furthermore, we show how to increase the reaction rate significantly by distributing the active porous material within the reactor using a high-level implementation of topology optimization.

Consider a countable collection (t) of particles located on a countable group, performing a critical branching random walk where the branching rate of a particle is given by a random medium uctuating both in space and time. Here we study the case where the time{space random medium (t) (called catalyst) is also a critical branching random walk evolving autonomously while the local branching rate...

a novel chemically modified electrode containing prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. the electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. the film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. results showed at bare gc electrode, a...

Pervaporation membrane reactors are ideal candidates to enhance conversion in reversible reactions generating water as a by-product. This equilibrium displacement can be enhanced through close integration of reaction and separation by way of catalytic membranes. In this research, catalytic hollow fibre pervaporation membranes for the close integration of reaction and separation will be develope...
