Анотація:

Whole sediment toxicity testing is an increasingly used means of assessing concentration dependent responses of benthic biota to contaminants as it enables sediments of single contaminants to be studied. However, concerns exist regarding the means of establishing heavy metal concentration gradients in sediments for use in toxicity testing. Metal spiking causes a plethora of poorly monitored changes in sediment geochemistry. Such changes to sediment chemistry induced by metal spiking, the procedural adjustments to minimise these and the resultant effects to organism response were the focus of t

The emission of metals during municipal solid waste incineration has become a question of considerable public and scientific concern in the light of evidence of their extreme toxicity. Sophisticated and expensive gas cleaning systems are required to meet the increasingly stringent EC atmospheric emission limits. While the technology for the clean-up of particulate matter and acid gases in flue gas is comparatively straightforward, the emissions of micro-pollutants such as heavy metals and dioxins remain a concern. Previous research on metal emissions has concentrated on overall mass balances,

This work was focused on the development of synthesis strategies for enhancing the energy product of spinel ferrite nanoparticles. The final goal was that of finding the best conditions to realize novel materials with improved magnetic properties, which could be used as building blocks for the realization of rare earth free - permanent magnet with higher energy products than commercial ferrites (i.e. strontium ferrite). To this aim, we focused on quasi-zero-dimensional magnetic materials and as possible strategies to enhance their performances we explored the coupling at the nanoscale with mag

Iron oxide nanoparticles (NPs) are promising materials for use in many applications, including new cancer treatments and in cleaning water, because they exhibit size-dependent magnetic and absorptive properties. NP properties are caused by structural attributes of the NPs, like surface disorder and cation vacancies. However, NP synthetic methods also impact structure, therefore properties, of NPs. Furthermore, the synthetic method is often changed in order to change the core diameter of NPs. Determining if properties are caused by the dimensions of the NP is impossible if there are also struct

Complementary critical perspective paradigms are introduced including comments on narrative and social construction. In relation to this context, th
