Abstract:
Many species of Talaromyces of marine origin could be considered as non-toxigenic fungal cell factory. Some strains could produce water-soluble active biopigments in submerged cultures. These fungal pigments are of interest due to their applications in the design of new pharmaceutical products. In this study, the azaphilone red pigments and ergosterol derivatives produced by a wild type of Talaromyces sp. 30570 (CBS 206.89 B) marine-derived fungal strain with industrial relevance were described. The strain was isolated from the coral reef of the Réunion island. An alternative extraction of the fungal pigments using high pressure with eco-friendly solvents was studied. Twelve different red pigments were detected, including two pigmented ergosterol derivatives. Nine metabolites were identified using HPLC-PDA-ESI/MS as Monascus-like azaphilone pigments. In particular, derivatives of nitrogen-containing azaphilone red pigment, like PP-R, 6-[(Z)-2-Carboxyvinyl]-N-GABA-PP-V, N-threonine-monascorubramin, N-glutaryl-rubropunctamin, monascorubramin, and presumed N-threonyl-rubropunctamin (or acid form of the pigment PP-R) were the major pigmented compounds produced. Interestingly, the bioproduction of these red pigments occurred only when complex organic nitrogen sources were present in the culture medium. These findings are important for the field of the selective production of Monascus-like azaphilone red pigments for the industries.

Abstract:
Microalgae productive chains are gaining importance as sustainable alternatives to obtain natural pigments. This work presents a review on the most promising pigments and microalgal sources by gathering trends from a 10-year bibliometric survey, a patents search, and an industrial and market analysis built from available market reports, projects and companies’ webpages. The performed analysis pointed out chlorophylls, phycocyanin, astaxanthin, and β-carotene as the most relevant pigments, and Chlorella vulgaris, Spirulina platensis, Haematococcus pluvialis, and Dunaliella salina, respectively, as the most studied sources. Haematococcus is referred in the highest number of patents, corroborating a high technological interest in this microalga. The biorefinery concept, investment in projects and companies related to microalgae cultivation and/or pigment extraction is increasingly growing, particularly, for phycocyanin from Spirulina platensis. These pieces of evidence are a step forward to consolidate the microalgal pigments market, which is expected to grow in the coming years, increasing the prospects of replacing synthetic pigments by natural counterparts.

Abstract:
Demand for microbial colorants is now becoming a competitive research topic for food, cosmetics and pharmaceutics industries. In most applications, the pigments of interest such as polyketide-based red pigments from fungal submerged cultures are extracted by conventional liquid–liquid extraction methods requiring large volumes of various organic solvents and time. To address this question from a different angle, we proposed, here, to investigate the use of three different aqueous two-phase extraction systems using either ammonium- or imidazolium-based ionic liquids. We applied these to four fermentation broths of Talaromyces albobiverticillius (deep red pigment producer), Emericella purpurea (red pigment producer), Paecilomyces marquandii (yellow pigment producer) and Trichoderma harzianum (yellow-brown pigment producer) to investigate their selective extraction abilities towards the detection of polyketide-based pigments. Our findings led us to conclude that (i) these alternative extraction systems using ionic liquids as greener extractant means worked well for this extraction of colored molecules from the fermentation broths of the filamentous fungi investigated here; (ii) tetrabutylammonium bromide, [N4444]Br-, showed the best pigment extraction ability, with a higher putative affinity for azaphilone red pigments; (iii) the back extraction and recovery of the fungal pigments from ionic liquid phases remained the limiting point of the method under our selected conditions for potential industrial applications. Nevertheless, these alternative extraction procedures appeared to be promising ways for the detection of polyketide-based colorants in the submerged cultures of filamentous fungi.

Abstract:
Pigments from wood-decay fungi (specifically spalting fungi) have a long history of use in wood art, and have become relevant in modern science due to their longevity and colorfastness. They are presently under investigation as colorants for wood, bamboo, oils, paints and textiles. Major hurdles to their commercialization have been color repeatability (in that the same strain of the same species of fungus may produce different colors over time), and the binding of the pigments to glass storage containers. This is persistent as they do not naturally exist in a loose form. Due to these issues, the ‘standard’ color for each was historically determined not by the amount of pigment, but by the color in a solution of dichloromethane (DCM), using the CIE L*a*b colorspace. This method of standardization severely limited the use of these pigments in industrial applications, as without a dry form, standard methodologies for repeatable color processing into other materials could not be easily implemented. Recent studies have developed a method to crystalize the red pigment from Scytalidium cuboideum (Sacc. & Ellis) Sigler & Kang, producing a highly pure (99%) solid crystal named ‘Dramada’. Herein a method is detailed to compare the molarity of this crystallized pigment to variations in the color, to determine a color saturation curve (by weight) for the pigment from S. cuboideum in DCM and acetone. The molarities for this experiment ranged from 0.024 mM to 19 mM. Each molarity was color read and assigned a CIEL*a*b* value. The results showed that there was a correlation between the molarity and color difference, with the maximum red color occurring between 0.73 mM and 7.3 mM in DCM and between 0.97 mM to 0.73 mM in acetone. Extremely low molarities of pigment produced strong coloration in the solvent, and changes in molarity significantly affected the color of the solution. Having a saturation and color curve for the crystal ‘Dramada’ from S. cuboideum will allow for the reliable production of distinct colors from a known quantity (by weight) of pigment, erasing the final hurdle towards commercial development of the crystallized pigment from S. cuboideum as an industrial dyestuff.

Abstract:
ABSTRACTLead white is a man-made white pigment commonly used in works of art. In this study, the possibility of radiocarbon dating lead white pigments alone and in oil paints was explored using well-dated lead white pigments and paints. Resulting14C ages on lead white pigments produced following the traditional stack process, where carbonate groups results from the incorporation of CO2originating from fermentation, matched the production years, while radiocarbon dating of lead white made using other industrial processes indicate that14C depleted CO2was used in their production. The method was applied to two case studies, where lead carbonate samples were dated in two oil paintings, one Baroque and one from the 20th century. We hereby show that the lead white pigment can be dated by14C and used as proxy for the time of creation of an artwork. Additionally, a two-step method was developed to allow14C analysis of both the lead white pigment and oil binder from the same sample. A single lead white paint sample can yield two distinct radiocarbon ages, one from the carbonate and one from the natural organic binder. This study thus proposes new strategies for14C dating of artworks.

Abstract:
Abstract Since their industrial introduction in the 1980s, DPP pigments now constitute a highly important group of high-performance carbonyl pigments. The DPP system was first discovered by accident in 1974, and was subsequently re-investigated by Ciba Geigy who recognized its potential to provide commercial organic pigments. DPP pigments exhibit strong similarities compared with quinacridone pigments, in terms of their molecular and crystal structures and their properties, including low solubility and excellent fastness properties. X-ray crystal structural analysis has demonstrated that their technical performance is the result of intermolecular hydrogen bonding and π–π stacking interactions in the crystal lattice structure. Based on a simple retrosynthetic analysis, an efficient synthetic process was developed by Ciba Geigy for their large-scale manufacture. DPP pigments currently provide orange through to reddish violet shades and have become of special importance in providing brilliant saturated red shades with the outstanding durability required for applications such as automotive paints.

Abstract:
Aluminium pigments are used in industrial and decorative coatings, automotive industry and printing inks. The encapsulation of aluminium pigments is used because the industry wants to avoid the organic solvents, for environmental reasons, by shifting towards water-borne systems. However, aluminium pigments easily react with water and a large amount of hydrogen is released leading to degradation of optical properties. This work presents experimental results concerning the encapsulation of aluminium pigments in silica matrices, by a sol-gel method using TEOS as precursor and ethylendiamine or ammonia as catalysts for the hydrolysis and condensation reactions. The samples of encapsulated pigments were characterized by gas stability tests: a boiling method and a gassing method.

Abstract:
At various points in human history, tattooing has been ubiquitous on almost every continent on Earth, used for reasons of aestheticism, religious beliefs or for social purposes. To study the art of tattooing with respect to a particular culture, one must always be critical to any references to the practice (written, pictorial or artefactual) due to issues of translation and misinterpretation. Complete verification may only come with the discovery of actual tattooed human remains. In combination with artefactual and anthropological evidence, these remains not only provide physical proof of the practice in a culture's ancestry but also possess the ability to link various other forms of physical evidence, which on their own would remain speculative. By its very nature, tattooing may only exist while the bearer is alive. Once the owner dies, the skin, along with the tattoo, decomposes (under normal decomposition conditions) and is lost forever. However, tattoos may survive if the dermal layers of the skin are preserved, either by natural or artificial means. The processes of mummification in various civilisations have provided us with a rare opportunity to study the art and processes of tattooing in antiquity. Existing tattooed mummified remains have been found in: Egypt; Siberia; Eastern Central Asia; Greenland; Alaska and St. Lawrence Islands; Central Andes (Peru and Chile); Philippines; New Zealand and Italy. Existing literature regarding the analysis of tattooing inks and pigments once deposited into the skin is very limited. Comparatively, the industrial organic pigments used to colour the majority of modern tattooing inks sold today have not been officially approved by any regulating body and as such, manufacturers are not required to disclose the chemical ingredients of their products. Chemical identification of these tattoo pigments post-procedure will aid medical practitioners in the event of complications or for the purposes of tattoo removal. Forensically, tattoos are often one of the distinguishing features used in the identification of victims of crime or accidents. Experiments were carried out using an animal model (Sus scrofa) for the tattooing. Given the theoretically large but ultimately limited range of substances available to both ancient and modern tattooists, the premise of the experiment involved surveying the literature regarding possible tattooing pigments and either obtaining or reproducing a careful selection of these in the laboratory. These pigments were then tattooed onto the ii animal model and after allowing for the essential healing period, the tattooed areas were excised, with those tattooed with traditional pigments subjected to various simulated mummification environments.

Abstract:
Questo lavoro di tesi ha avuto come scopo la preparazione di film dei semiconduttori organici Indaco e Chinacridone con metodi da soluzione, che sono i preferiti per la fabbricazione di dispositivi. Per la caratterizzazione dei film si è utilizzata la microscopia Raman nell’intervallo dei numeri d’onda delle vibrazioni reticolari, per identificare la natura della fase cristallina presente. Indaco e Chinacridone sono pigmenti fortemente insolubili in tutti i solventi organici, a causa della presenza dei forti legami a ponte di idrogeno intermolecolari che ne influenzano notevolmente le proprietà di stato solido. Questo rende difficile l’ottenimento di film omogenei per deposizione diretta di loro soluzioni. Per ovviare al problema, si è utilizzata una strategia di letteratura, che passa attraverso la preparazione di loro derivati solubili, con una reazione di protezione dei gruppi amminici presenti sulle molecole con gruppi termolabili (tBoc). Una volta depositato su substrato, il pigmento originale può essere rigenerato per riscaldamento del film. L’analisi Raman ha permesso di caratterizzare strutturalmente per la prima volta i film preparati con questa procedura. In particolare si è verificato che sui film di Indaco è sempre presente il polimorfo B, in accordo con quanto trovato nei film preparati con metodi di deposizione da vapore. Per quanto riguarda il Chinacridone invece dell’attesa β, la fase ottenuta è la metastabile α’, ottenibile in fase bulk solo in condizioni drastiche. In entrambi in casi si conferma la selettività del substrato verso un polimorfo specifico.

Abstract:
Corrosion is the gradual deterioration of materials by chemical reaction with their environment, leading to the formation of less desirable material, which lacks in functionalities of the system. Corrosion resistant coatings have being an active subject of research since a while. Aiming at the replacement of toxic anti-corrosion pigments in organic coating industries, in the last two decades several environmentally friendly pigments have been studied, which involves passivating compounds such as molybdates, permanganates, vanadates, and tungstates. Cerium compounds are attaining more attention due to their potential as corrosion inhibitors. The present work aims at the experimental investigation on the effect of zirconium on corrosion resistance of ceria nanoparticles, in epoxy resins. Ceria and cerium zirconium mixed oxide nanoparticles was prepared by co-precipitation method. Ceria and cerium zirconium mixed oxide nanoparticles were dispersed in epoxy resin and the composites were spin coated on mild steel specimens. Surface studies was done using AFM and electrochemical studies were done one the coated surfaces using Zahnier IM6 modular electrochemical workstation. The Impedance spectra and surface structure studies showed highly improved corrosion resistance for ceria and cerium zirconium mixed oxide nanoparticles added epoxy primers as compared to unmodified epoxy resin primer. UV resistance of the coatings were found to be improved for ceria and cerium zirconium mixed oxide nanoparticles based coatings.
