Estuaries and tidal rivers are highly dynamic transitional zones where marine riverine processes interact, creating complex hydrodynamic environments. These regions influenced by natural phenomena such as oscillations, storm surges, river flow, well human activities like water management, hydropower operations, flood protection, navigation. Effective management of these environments relies on understanding predicting their behavior, particularly under extreme conditions flooding or abrupt...
Raman spectroscopy (RS), for its robust analytical capabilities under constant development, is a powerful method the identification of various materials, in particular pigments cultural heritage. Characterization artist’s palette fundamental importance correct formulation restoration intervention as well preventive conservation artworks. Here we examine number and variability research studies exploiting Bravo handheld spectrophotometer relying on excitation signal with temperature-shifted...
The early detection of bronze disease is a significant challenge not only in conservation science but also various industrial fields that utilize copper alloys (i.e., shipbuilding and construction). Due to the aggressive nature this corrosion pathway, developing methods for its pivotal. presence trihydroxychlorides main key indicator ongoing autocatalytic process. Commonly used pigment identification, reflectance imaging spectroscopy (RIS) or fiber optics (FORS) was recently employed mapping...
The characterization and conservation of materials constituting contemporary art pose a significant challenge for scientists restorers due to the wide variability heterogeneity in their compositions chemical instability. aim this study is contribute understanding composition ageing artworks, specifically Analytical Painting. To purpose we examine an acrylic painting on raw canvas, Tela by Giorgio Griffa (1973), model samples purposely prepared together with painter. Felt‐tip marker vandalic...
Copper alloy artworks are particularly subjected to chloride attack, which may trigger bronze disease. Therefore, early identification of the phenomenon is crucial in order stabilize reactive copper (CuCl) and remove harmful corrosion products (atacamite polymorphs). Confocal Raman Microspectroscopy (CRM) has proven be effective for detection small amounts atacamite, ascribable initial phases corrosion. The handling often difficult or even impossible given their large size weight, sampling...
Raman spectroscopy (RS) is a powerful non-invasive tool for the characterization of materials. However, fluorescence effect often hampers detectability relatively weak vibrational signal. Several approaches were exploited to overcome this limit. This work, in particular, evaluates performance an situ portable sequentially shifted excitation (SSE™) spectrometer applied examination artistic historical pigment powders enclosed glass vials. The explored handheld employs dual,...
Abstract Madder lake is the most utilized anthraquinone dyestuff in artworks. Its main constituents (alizarin and purpurin, together with other natural dyes) form an organometallic complex (the lake) insoluble water by precipitation or adsorption of dye onto inorganic substrate. Raman spectra madder are strongly affected fluorescence, making its identification spectroscopy difficult impossible. In this work, we prepared different lakes according to historical recipes characterized them X-ray...
We have studied, by density functional theory, the interaction between luteolin and Ag, devising two complexes where an Ag14 cluster faces different sites of molecule. The are identified as quinoid-like cathecol-like, CPLX1 CPLX2, respectively. Raman SERS spectra were measured at excitation wavelengths. Luteolin solid samples from suppliers spectra, possibly associated with arrangements in solids. These well reproduced our DFT calculations. Assignment vibrational modes luteolin–Ag14 is...
The public expected color from the early photographic images, yet, daguerreotypes—the first commercially available process—failed to register natural colors. Daguerreotypists developed several coloring methods solve this inconvenience after 1840. Scientific analyses of hand-colored daguerreotypes are limited, and primary information sources manuals patents. This study aims contribute knowledge hand-coloring techniques, which impacts conservation practices, mainly cleaning procedures...
The governmental Flood Hazard Identification and Mapping Program (FHIMP) seeks to update standards for flood mapping risk area definition in Canada. Within this initiative, Environment Climate Change Canada (ECCC) has been mandated provide 2D simulations of water levels the St. Lawrence fluvial estuary estimate return periods extreme under historical future conditions. Long-term fine-scale hydrodynamic are necessary reproduce accurately complex interplay hydrological, meteorological tidal...
This study investigates the interactions between tides, storm surge, river flow, and power peaking in microtidal Neretva River estuary, Croatia. Based on existing NS_Tide tool, proposes a new non-stationary harmonic model adapted for conditions, which incorporates linear as well quadratic discharge terms. enhances NS_Tide's ability to accurately predict water levels from tide-dominated sections downstream discharge-dominated areas upstream. was identified dominant factor predicting stage at...
In this work, a tempera painting of uncertain attribution from the Uffizi Galleries was studied. The painting, which portraits man with apparently Botticellian features, probably created by one most skilled forgers early 20th century, Umberto Giunti. He used flat tile as support, covered preparatory layers emulating wall painting. To shed light on authorship it crucial to investigate its composing materials, well execution technique and state conservation. end, non-invasive spectroscopic...
