Unveiling street art: A multimodal and multitechnique approach for analyzing and mapping painting materials on large murals.

Street art murals are increasingly recognized as valuable contemporary artworks, often attaining significant artistic, historical, and social importance. As these murals become integral parts of cultural heritage, finding efficient strategies for their conservation is crucial. However, their typical large surface areas, heterogeneous materials, and high variability in exposure to environmental and pollution factors pose significant challenges in establishing appropriate analytical strategies to obtain the necessary information.

Integrated Chemical Mapping and Analytical Pyrolysis for Tracking the Evolution of Street Art Material.

The chemical investigation of modern art materials and synthetic paint materials has been a major focus of research in cultural heritage science over the past decade. Since the 1970s, street art has become an influential cultural movement with significant artistic and social impact in modern cities, and the conservation of relevant artworks related to urban neo-muralism has been increasingly recognized. Understanding these materials is critical to developing conservation strategies, as their composition continues to change with industrial innovation and regulatory changes.

Unveiling the Secret Chemistry of Street Art by a Multitechnique Approach.

In recent years, graffiti and street art have gained recognition as legitimate art forms, deserving of the same care and attention as traditional art. As a result, conservators and restorers are now working to develop standardized guidelines for the cleaning, conservation, and restoration of these vibrant works. Our study takes a closer look at the materials used in street art, specifically the spray varnishes used by artists.

Nanostructured Strategies for Melanoma Treatment-Part I: Design and Optimization of Curcumin-Loaded Micelles for Enhanced Anticancer Activity.

: Melanoma is a pathology that affects a large part of the population, and the currently available therapies have many limitations, including the selective targeting of the site of action. This study explores the development of curcumin (CUR)-loaded nanostructured delivery systems for topical melanoma treatment, addressing CUR's limitations in bioavailability, solubility, and stability. : Binary surfactant mixtures of Vitamin E-TPGS (TPGS) and Kolliphor ELP (ELP) were selected to form stable micelles for curcumin encapsulation.

A Thermal Analytical Study of LEGO Bricks for Investigating Light-Stability of ABS.

Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer widely used in several everyday life applications; moreover, it is also one of the most employed plastics in contemporary artworks and design objects. In this study, the chemical and thermal properties of an ABS-based polymer and its photo-degradation process were investigated through a multi-analytical approach based on thermal, mass spectrometric and spectroscopic techniques. LEGO building blocks were selected for studying the ABS properties.

A versatile method to fingerprint and compare the oxidative behaviour of lipids beyond their oxidative stability.

In this work we propose the use of isothermal thermogravimetry to evaluate the oxidative stability of a lipid and to evaluate how the glyceride composition affects the entire oxidative process, to quantify the oxidation undertaken by the lipid, and numerically compare the oxidative behaviour of different lipids. The innovative aspect of the present method lies in the acquisition of a prolonged "oxygen uptake" curve (4000-10,000 min) of a lipid under oxygen and in the development of a semi-empirical fitting equation for the experimental data. This provides the induction period (oxidative stability), and allows to evaluate the rate of oxidation, the rate and the magnitude of oxidative degradation, the overall mass loss and the mass of oxygen taken by the lipid upon time.
