Advanced Biopolymer-Based Nanocomposites and Hybrid Materials

The exploitation of naturally occurring polymers to engineer advanced nanocomposites and hybrid materials is the focus of increasing scientific activity, explained by growing environmental concerns and interest in the peculiar features and multiple functionalities of these macromolecules. Natural polymers, such as polysaccharides and proteins, present a remarkable potential for the design of all kinds of materials for application in a multitude of domains. This Special Issue collected the work of scientists on the current developments in the field of multifunctional biopolymer-based nanocomposites and hybrid materials with a particular emphasis on their production methodologies, properties, and prominent applications. Thus, materials related to bio-based nanocomposites and hybrid materials manufactured with different partners, namely natural polymers, bioactive compounds, and inorganic nanoparticles, are reported in the Special Issue Advanced Biopolymer-Based Nanocomposites and Hybrid Materials

A cybernetic model to describe the dynamics of myeloma cell cultivations

Special Issue on Life System Modeling and Bio-Inspired Computing for LSMS 2007 Copyright © 2008 Elsevier Inc. All rights reserved.A cybernetic model is developed to model the dynamics of mammalian cell growth and metabolism. Especially, the formation of the byproducts such as ammonia and alanine are taken into account in the model. The production of these byproducts is mainly regulated by the competition between transamination and deamination. In addition, amino acids utilization for protein formation and energy supply is also involved due to lysine limitation found in our experiments. The model is able to simulate the transients of the substrate and byproduct concentrations, the viable and dead biomass as well as the intracellular concentrations of the intermediates and enzymes. Myeloma cell cultivations are applied to validate the model. © 2008 Elsevier Inc.
