As product development becomes increasingly complex, the demand for earth's mineral ores increases and with it, challenge to achieve global “sustainability”. Chemical elements are building blocks of natural resources which sourced from across planet manufacture globally traded goods. While technological, social economic progress accelerates, evaluating sustainability these remains a challenge. ...

Recent developments in the study of element abundances and their impact on our understanding of the evolution of stars and the chemical evolution of the Galaxy are described. In particular, problems that may beneet, or beneet from, work on binary stellar populations are highlighted. These include: diierent mixing processes in globular cluster and eld stars, evidenced by Li and nuclei in the NeN...

Stellar evolution computations provide the foundation of several methods applied to study the evolutionary properties of stars and stellar populations, both Galactic and extragalactic. The accuracy of the results obtained with these techniques is linked to the accuracy of the stellar models, and in this context the correct treatment of the transport of chemical elements is crucial. Unfortunatel...

[Bio]chemical sensors, defined as devices which convert a chemical state into an electrical signal [1], have been the subject of a strong development during the past few decades. A sensor has essentially two parts (Fig. 1): a detecting element, in which the presence of an external stimulus produces a change of some property (optical, mechanical, electrical ...), and a transducing element, which...

 is study aims to explore the eff ect of chemical element symbols in students’ identifi cation of 2D chemical structural formulas. A chemical conceptual questionnaire, event-related potential experiments and interviews were administered to fi ‚ y university students in this study.  e results revealed that high achieving students perfprmed diff erent brain activities and strategies to identify...
