Characterisation and assessment of two green aging methods for silver mock-up systems using multi-analytical techniques

Due to the high values of historical silver artefacts, artificially aged mock-ups are often used for the development of conservation concepts and treatments in the field of conservation and heritage study. However, some chemicals used in recent…

Synthesis and Evaluation of the Photochemical Properties of Heterocyclic Hemiindigos

This study reports a series of novel heterocyclic hemiindigos (Het-HI) synthesized via the condensation of indoxyl acetate with various heteroaromatic aldehydes. The influence of electronrich and electron-poor heterocycles on the photochemical and…

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Abstract The development of high‐efficiency near‐infrared (NIR) emitters for organic light‐emitting diodes (OLEDs) and organic semiconductor lasers has become an important target in organic photonics. Herein, it is demonstrated that donor‐acceptor…

Quantifying nucleation in flow by video-FLIM

During a precipitation experiment in microfluidics, crystals appear in the flow. Using a molecule that turns fluorescent in the solid phase, these crystals can be counted, measured and their polymorph identified. From this collection of data, the…

Modulation of photoacoustic NIR BODIPY self-assembly in theranostic solid lipid nanoparticles via alpha-group variation: influence on spectral and nanostructural properties

Loading drug nanovectors with a high quantity of near-infrared organic dye considerably increases their absorption cross-section and favors their detection as theranostic agents with photoacoustic imaging. In a previous study, solid lipid…

Natural and Artificial Aging Methods For Silver Mock‐ups In Recent Conservation And Heritage Studies: A Short Review

Silver has been widely used for art and heritage objects throughout history, due to its excellent ductility, malleability and brilliant metallic lustre. However, silver objects tarnish over time and must be regularly treated to maintain their…

Structure–Optical Properties Relationships in Cobalt-Based Purple Pigments Used by Robert Delaunay

Following the industrial revolution and the modernization of chemistry, purple became one of the most popular colors in the palettes of late 19th- to 20th-century painters. Among them, Robert Delaunay (1885–1941) was one of the key artists of the…
