A method for dating copper/bronze archaeological objects aged in atmospheric environments is proposed based on the specific signals for cuprite and tenorite corrosion products measured through the voltammtry of microparticles method. The tenorite/cuprite ratio increased with the corrosion time and fitted to a potential law that yielded a calibration curve usable for dating purposes.
The aim of this paper is to contribute towards the successful management of heritage landscapes. Many cultural landscapes represent high heritage value and should be classified as heritage landscapes; therefore, special tools should be considered to be used in managing them. These landscapes should be evaluated according to heritage science criteria and good practice guidelines should be established. Several useful heritage landscape evaluation criteria were identified and characterised, and their relative importance was analysed, enabling the establishment of a heritage value hierarchy by means of a weighted linear combination. This is significant in the context of land management measures for countryside valorization promoting rural development. However, this approach also requires awareness of the link between the present cultural landscape and the history of the people that have interacted with the area involved. This is also important for the establishment of a priority ranking system for monitoring criteria indicators. A method for doing this is also proposed by the authors.
The complexation of humic matter with lead in natural water conditions was studied by differential pulse anodic stripping voltammetry (DPASV) using a mercury film of a Nafion-coated mercury film as the working electrode. The results clearly show that the Nafion film greatly minimizes the adsorption of humics on the electrode. Besides adsorption, other effects on the voltammetic signal are discussed, such as the degree of lability, ligand heterogeneity, and the metal-to-ligand concentration ratio at the electrode surface.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
