Fully Bio-Sourced Nylon 11/Raw Lignin Composites: Thermal and Mechanical Performances

Ecofriendly fully bio-composites based on polyamide 11 (PA11) and lignin have been prepared on the entire concentration range using a twin-screw extruder. In this work, PA11 was blended with lignin by direct extrusion technology without any chemical pre- or in-situ- modifications or physical pretreatments. The presence of various organic and inorganic impurities in the selected technical lignin have been maintained. The incorporation of this cheap renewable material from biomass in bio-based PA11 was inspected by an array of characterization tools. Also, the effect of the presence of lignin on the morphology and on the mechanical properties of the resulting materials was examined. Finally, in-situ investigation of structural evolution in PA11 induced by the presence of lignin was analyzed by Fast Scanning Chip Calorimetry

Techniques for Securing Web Content

Abstract: This paper analyzes the dangers to which web content is exposed, demonstrates how data from the Internet can be gathered and used to obtain profit, how an application can stealthily make use of complicated processing without implementing them and how a website can be cloned in real time. For the considered attacks and vulnerabilities I present, explain, group and evaluate the existing solutions to secure content and last but not least, I suggest a new solution: a library for link encryption
