Silver nanoparticles coated with natural polysaccharides as models to study AgNP aggregation kinetics using UV-Visible spectrophotometry upon discharge in complex environments

This study provides quantitative information on the aggregation and dissolution behaviour of silver nanoparticles (AgNPs) upon discharge in fresh and sea waters, represented here as NaCl solutions of increasing ionic strength (up to 1 M) and natural fjord waters. Natural polysaccharides, sodium alginate (ALG) and gum Arabic (GA), were used as coatings to stabilize the AgNPs and the compounds acted as models to study AgNP aggregation kinetics. The DLVO theory was used to quantitatively describ...

2004-2009 CO2GeoNet Activities: Final OGS-DOGA Results in Oceanography

The initial partnership will be between 13 institutes, most of which have a long and established history of research in geological storage. Some new players are also included, either because they are expected to have significant national strategic profile in future CO2 storage projects, or they have capabilities which can be realigned to strengthen the network, or even bring uniqueness. For the first time in an EC FP project, marine biologists will be drawn into this research topic.. Europe's...

Two decades of seismic risk communication in Europe: a scoping review

Although earthquakes are a threat in many countries and considerable resources have been invested in safety regulations, communities at risk often lack awareness and preparedness. Risk communication is a key tool for building resilient communities, raising awareness, and increasing preparedness. Over the past two decades, risk communication has evolved significantly. This has led to a reorientation from a predominantly “one-way”, top-down communication model to the p...
