The peppermint Initiative was created to overcome the lack of standardization in exhaled breath analysis. It is an inter-analytical platforms-benchmarking study, which was carried out in the OBiAChem laboratory. Concretely, in each analytical platform, the defined peppermint protocol was repeated on the exhaled breath of at least 10 subjects to monitor specific metabolites of the peppermint oil in the exhaled breath. With the resulting data, a statistical analysis will be carried out and should represent the variability range between laboratories and different types of instrumentation. Concerning the OBiAChem laboratory, the exhaled breath was sampled in Tedlar® bags and the target VOCs were analyzed by a TD-GC×GC-HRTOFMS. A previous optimization step on the exhaled breath sampling method was done and this determined the suitable sampling bags for the exhaled breath analysis, 1L Tedlar® bags. The data analysis highlighted that almost all of the monitored metabolites of peppermint oil gave reproducible results leading to the conclusion that the exhaled breath sampling method which was used is a reproducible method.

Industrial energy efficiency has been recognized as a major contributor, in the broader set of industrial resources, to improved sustainability and circular economy. Nevertheless, the uptake of energy efficiency measures and practices is still quite low, due to the existence of several barriers. Research has broadly discussed them, together with their drivers. More recently, many researchers have highlighted the existence of several benefits, beyond mere energy savings, stemming from the adoption of such measures, for several stakeholders involved in the value chain of energy efficiency solutions. Nevertheless, a deep understanding of the relationships between the use of the energy resource and other resources in industry, together with the most important factors for the uptake of such measures—also in light of the implications on the industrial operations—is still lacking. However, such understanding could further stimulate the adoption of solutions for improved industrial energy efficiency and sustainability.

Fracture, fatigue, and other subcritical processes, such as creep crack growth or stress corrosion cracking, present numerous open issues from both scientific and industrial points of view. These phenomena are of special interest in industrial and civil metallic structures, such as pipes, vessels, machinery, aircrafts, ship hulls, and bridges, given that their failure may imply catastrophic consequences for human life, the natural environment, and/or the economy. Moreover, an adequate management of their operational life, defining suitable inspection periods, repairs, or replacements, requires their safety or unsafety conditions to be defined. The analysis of these technological challenges requires accurate comprehensive assessment tools based on solid theoretical foundations as well as structural integrity assessment standards or procedures incorporating such tools into industrial practice.
