Integrated Analysis of Permeability Reduction Caused by Polymer Retention for Better Understanding Polymer Transport

New Polymer Catalytic Membranes for Nitrite Reduction: Experimental Assessment

In this work we report the experimental assessment of the performance of a new catalytic hollow fiber reactor with supported Pd catalyst for nitrite removal from polluted waters. The reactor configuration facilitates working at low flowrate and hydrogen concentrations in order to improve the selectivity of the reduction reaction towards nitrogen, thus, inhibiting the formation of ammonia. Pd ca...

Molecular Simulation in Polymer Science: Understanding Experiments Better

New techniques and applications of atomistic molecular simulation methods are reported. Their aim is to provide a better understanding of the molecular basis of experimental results. To this end, calculations are performed of experimentally measurable observables. These are then compared to experimental results, thus validating the computational models and procedures. Finally, the simulations a...

Numerical analysis of reactant transport in the novel tubular polymer electrolyte membrane fuel cells

In present work, numerical analysis of three novel PEM fuel cells with tubular geometry was conducted. Tree different cross section was considered for PEM, namely: circular, square and triangular. Similar boundary and operational conditions is applied for all the geometries. At first, the obtained polarization curve for basic architecture fuel cells was validated with experimental data and then...

Hyperbranched Polymer Integrated Membrane for the Removal of Arsenic(III) in Water

This work demonstrates the synthesis, characterization and application of a hyperbranched polyethyleneimine/polysulfone (HPEI/PSf) thin fi lm composite (TFC) membrane. The membrane was accessed via an interfacial polymerization of trimesoyl chloride and HPEI. The membrane samples were characterized by Fourier Transform Infrared-Attenuated Total Refl ectance (FTIR-ATR) s...
