To attempt to optimize the anomalous phenomena that today go under the label "cold fusion" the experimentalist should be aware of the many aspects of the behavior of hydrogen in metals and of its entry into and egress from metals. This paper discusses the equilibrium characteristics of the isotopes of hydrogen in metals. The first section discusses the thermodynamics of the terminal solutions o...

Abstract: The aim of this paper is to investigate trade unionists leaders' perspective on Industry 4.0. Questionnaires and interviews were carried out. Two conclusions pointed out: a fragmented understanding the concept low participation workers in implementation process. Looking forward just transition, improvement either conceptual grasp workers' are necessary.

Abstract Various high-purity metals endow renewable energy technologies with specific functionalities. These become heavily intertwined in products, complicating end-of-life treatment. To counteract downcycling and resource depletion, maximising both quantities qualities of materials recovered during production recycling processes should be prioritised the pursuit sustainable circular economy. ...

Polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) and polybrominated diphenyl ethers (PBDEs) were characterized and quantified in stack gas from secondary ventilation systems from five different steelmaking plants. The concentrations of 2,3,7,8-substituted PBDD/Fs (2,3,7,8-PBDD/Fs) and PBDEs were 0.036–0.19 ng/Nm (0.32–4.33 pg toxic equivalency (TEQ)/Nm) and 3.11–40.0 ng/Nm, respecti...

Metallurgical activities have been undertaken in northern South America (NSA) for millennia. However, it is still unknown how far atmospheric emissions from these activities have been transported. Since the timing of metallurgical activities is currently estimated from scarce archaeological discoveries, the availability of reliable and continuous records to refine the timing of past metal depos...

A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...
