Preparation and Characterization of Films Based on Alginate and Aloe Vera

Sodium alginate films with aloe vera extract were prepared by the casting/solvent evaporation technique. The resulting films were characterized by differential scanning calorimetry, Fourier transform-infrared spectroscopy, scanning electron microscopy, and mechanical and water absorption tests. The in vitro degradation of the films was also investigated over 14 days. Results show that aloe vera contributes to b...

Welcome to a brand new year of 2010! In this editorial, we bring you the latest update concerning rapid prototyping technologies,which of coursemany of you are aware, include many terminologies such as layer manufacturing and solid freeform fabrication, amongst others. The longstanding need to standardize the terminologies within the rapid prototyping andmanufacturing industry has nowbeenmetwith a new ASTMInter...

We end the year 2009, our fourth year of existence, with three state-of-the-art papers and two technical papers. In the first formal paper, Liebschner describes current efforts in identifying mechano-biological principles that are believed to guide tissue formation based on biomechanical loading. The goal of the research is to discuss a reverse engineering solution in a strategy that starts with the final produ...

Virtual and Physical Prototyping: Editorial

The second half of 2009 is rich in international events in virtual and physical prototyping, a quite active and relevant research field. The Virtual and Physical Prototyping journal is associated with two of these events. The first one is the ECCOMAS Thematic Conference on Tissue Engineering designed to be a major international forum for the discussion of the current state-of-the-art in the fields of Tissue Eng...

Study on the fatigue strength of AA 6082-T6 adhesive lap joints

A research study on the fatigue behaviour of aluminium alloy adhesive lap joints was carried out to understand the effect of surface pre-treatment and adherends thickness on the fatigue strength of adhesive joints. The adherend material used for the experimental tests was an aluminium alloy 6082-T6 in the form of thin sheets, and the adhesive used was a high strength epoxy (Araldite 420 A/B). The surface prepar...

Modeling and simulation of photofabrication processes using unsaturated polyest...

Several kinetic models have been proposed to simulate thermosetting cure reactions. The most complex models, based on a mechanistic approach of cure reactions, are developed based on the concepts of free radical polymerization and the mechanism of reactions with diffusion. However, mechanistic models are usually quite impractical for engineering purposes because of the difficulty in obtaining the model paramete...
