The objectives of this paper will be to discuss the issues related determination limits detection (LOD) in laser-induced breakdown spectroscopy (LIBS) analytical applications. derivation commonly used ‘3-sigma over slope’ rule and its evolution towards new official definition recently adopted by International Union Pure Applied Chemistry (IUPAC) illustrated. Methods for extending calculation LOD LIBS multivariate analysis also discussed, using as an example Cu traces cast iron samples LIBS.
Enrico Van Lint (Pisa, 1808–1884) was a very prolific photographer, active in Pisa the 19th century where he had prominent photographic atelier. He meticulous experimenter, investigating evolving activity of his historical period. While early works included calotypes using Fox Talbot’s methods, rapidly adopted collodion processes, becoming one most important Italian photographers that used this technique. At present time, vast number examples from Lint’s ateliers are preserved and archived...
In recent years, the use of Raman spectroscopy as a gemological tool has largely increased, in particular conservation science field where non‐destructive and contactless identification is required. this work, we show large amount information which possible to obtain with analysis on one most important gems, emerald, green variety beryl. particular, 14 not certified faceted emeralds have been studied by means standard micro‐Raman spectrometer, allowing also some fakes (garnet, glass,...
In recent years, the use of mobile Raman equipment as an archeological, artistic, and conservation tool has largely increased due to possibility obtain quick nondestructive compositional analysis on precious, vulnerable, unique art objects. particular, archeological museums can take great advantage in carrying out situ measurements short times without moving artifacts. this work, we report carried by portable instruments important jewelry collection dated back 17th–18th centuries preserved...
In this review, we report and critically discuss the application of LIBS for determination plasma-emission fundamental parameters, such as transition probabilities, oscillator strengths, Stark broadening shifts, emission lines in spectrum. The knowledge these parameters is paramount importance plasma diagnostics or quantitative analysis using calibration-free methods. first part, theoretical basis laid down; second main experimental analytical approaches by spectral line spectroscopic are...
Abstract The physical properties of silicate melts are critical importance for understanding magmatic and volcanic processes on Earth other planets. Most are, ultimately, a consequence the structural organization melt. Robust fully generalizable strategies prediction naturally occurring as functions composition, temperature, pressure remain challenging goal. Given origin macroscopic properties, Raman spectroscopy glasses, which provides information melt glass structure, may provide useful...
Alveolar macrophages are the first line of defence against detrimental inhaled stimuli. To date, no comparative data have been obtained on inflammatory response induced by different carcinogenic mineral fibres in three main macrophage phenotypes: M0 (non-activated), M1 (pro-inflammatory) and M2 (alternatively activated). gain new insights into toxicity mechanisms fibres, acute effects fibrous erionite, crocidolite chrysotile phenotypes THP-1 monocyte differentiation were investigated. The...
In the last decade, Raman spectroscopy has been used for routine investigation gemmological purposes, being non‐destructive and non‐invasive. addition, this technique grants short measurement times without any sample preparation. context, work is focused on spectroscopic characterization of different kinds blue gems, including sapphires, by comparing performance a handheld instrumentation along with micro‐Raman spectrometer, aim to provide certification get information provenance gems. The...
In the framework of a wide project aimed to study potential Raman spectroscopy in characterizing gems, jewels and jewellers’ collections, this work results micro‐Raman investigation on red gemstones are proposed. detail, set gems supplied by jeweller as representative current trade were analyzed using instrumentations equipped with different laser excitation sources. The obtained allow not only discriminating rubies from simulant fakes but also achieving useful information inclusions...
The recent upgrading of synchrotron radiation (SR) sources has favored, in the last few years, construction and design beamlines optimized for study cultural heritage materials, which may require ad hoc setups, specific spatial resolutions, detection limits. In field heritage, integrated approaches combining different techniques are often required, even at large facilities, where some offer possibility performing types measurements same point analysis, complementing preliminary information...
Gems, especially from remote areas, were highly demanded and valued in Byzantine times, often used for sacred Imperial purposes. Because of their imperishable nature, they re-used over time many them passed, one way or another, East to Western Europe. The history the gems set relics that survived medieval Europe is impossible reconstruct. exceptional opening St. John Baptist Siena, 200 years after last inspection, has made it possible study magnificent adorn it. Spinels, rubies, sapphires...
This work is a part of large scientific project aimed at highlighting the potential portable Raman equipment in characterizing jewelry materials preserved museums, carried out collaboration with gemologists and archeologists. In detail, we report results measurement campaign performed for study gems jewels well-known Medagliere section Paolo Orsi Regional Museum Siracusa (Sicily). The studied consist exquisite examples engraved loose really rare Hellenistic–Roman jewels, mainly coming from...
