“…In addition, there is a large and growing body of nanoenvironmental and nanoecotoxicological research (Selck et al ). This research is driven by questions of environmental risk because of the predicted rapid increases in environmental concentrations (Gottschalk et al ), the known bioavailability (Luoma et al ) and deleterious biological effects (Fabrega et al ), the suspected novel behavior of some NMs in environmental and biological systems (Luoma et al ; Taylor et al ), and the consequent complexities of risk assessment (Laux et al ). In addition, modeling projections using a “business as usual” scenario suggest that production will more than triple by 2020, with much of the output eventually being discharged to the environment (Sun et al ).…”

The present review covers developments in studies of nanomaterials (NMs) in the environment since our much cited review in 2008. We discuss novel insights into fate and behavior, metrology, transformations, bioavailability, toxicity mechanisms, and environmental impacts, with a focus on terrestrial and aquatic systems. Overall, the findings were that: 1) despite substantial developments, critical gaps remain, in large part due to the lack of analytical, modeling, and field capabilities, and also due to the breadth and complexity of the area; 2) a key knowledge gap is the lack of data on environmental concentrations and dosimetry generally; 3) substantial evidence shows that there are nanospecific effects (different from the effects of both ions and larger particles) on the environment in terms of fate, bioavailability, and toxicity, but this is not consistent for all NMs, species, and relevant processes; 4) a paradigm is emerging that NMs are less toxic than equivalent dissolved materials but more toxic than the corresponding bulk materials; and 5) translation of incompletely understood science into regulation and policy continues to be challenging. There is a developing consensus that NMs may pose a relatively low environmental risk, but because of uncertainty and lack of data in many areas, definitive conclusions cannot be drawn. In addition, this emerging consensus will likely change rapidly with qualitative changes in the technology and increased future discharges.

“…Artificial intelligence can be also a tool that can facilitate this step forward. Tribology will help to design low carbon footprint materials and implement them in a cost-efficient, predictive, and safe way [70][71][72][73][74][75]. Tribology will assist also the development of energy-and resource-efficient products and processes, in real systems.…”

This chapter describes a summary of the main tribological achievements carried out in TEKNIKER during the last 37 years. It covers the description of commercial and newly developed tribological test benches and case studies for a wide variety of applications. The examples refer to different tribological characterization tools for material selection (e.g., composition, surface treatments, lubricants). It makes emphasis in the failure mechanisms (pitting, scuffing, abrasion, adhesion, thermal fatigue, tribocorrosion, etc.) and friction simulation of a wide range of materials (seals, textiles, steels, cast iron, light alloys, ceramic, composites), tribological systems (mechanical components, biomaterials, tribolubrication), and environments (vacuum, ultrahigh vacuum, low or high temperature, and corrosive). A huge range of new testing equipment and protocols have been developed to simulate the mentioned failure mechanisms and working environments. This knowledge will make possible, in the future, to simulate at laboratory a still wider list of tribological systems and develop new standards. Tribology will help to implement materials solutions into energy and resource efficient products and process, to reduce carbon footprint.2 with more than 250 scientific contributions in congresses, journals, and books and 3 patents. It has been active in several international working groups and associations, in some of them, acting as Spanish representative:• The COST 516 about tribology (1995)(1996)(1997)(1998)(1999)(2000) • The COST 532 about tribotechnology of engines and transmissions
