Alizarin Grafting onto Ultrasmall ZnO Nanoparticles: Mode of Binding, Stability, and Colorant Studies. LANGMUIR : THE ACS JOURNAL OF SURFACES AND COLLOIDS 2021; 37:1446-1455. [PMID: 33470824 PMCID: PMC7877731 DOI: 10.1021/acs.langmuir.0c02981] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 12/14/2020] [Indexed: 05/24/2023]
Abstract
The demand is rising for colorants that are obtained from natural resources, tolerant to industrial processing methods, and meet color quality demands. Herein, we report how relevant properties such as thermal stability and photostability of the natural colorant alizarin can be improved by grafting it onto ZnO nanoparticles (NPs), allowing application in a warm extrusion process for the fabrication of polyamide fibers. For this study, ZnO NPs (diameter 2.0 ± 0.6 nm) were synthesized and subsequently functionalized with alizarin. The alizarin-coated ZnO NPs (i.e., dyed nanoparticles, DNPs) were characterized. Thermogravimetric analysis and ultraviolet-visible (UV-vis) studies revealed that alizarin coating accounts for ∼65% (w/w) of the total mass of the DNPs. A subsequent detailed characterization with Fourier transform infrared (FT-IR), 1H nuclear magnetic resonance (NMR), 13C cross-polarization magic angle spinning (CP-MAS) NMR, X-ray photoelectron spectroscopy (XPS), and quantum chemistry studies using various density functional theory (DFT) functionals and basis sets indicated that binding onto the ZnO NPs occurred predominantly via the catechol moiety of alizarin. Importantly, this grafting increased the thermal stability of alizarin with >100 °C, which allowed the processing of the DNPs into polyamide fibers by warm extrusion at 260 °C. Evaluation of the lightfastness of the DNP-dyed nylon fibers revealed that the changes in color quantified via the distance metric ΔE* of alizarin when embedded in a hybrid material were 2.6-fold better compared to nylon fibers that were directly dyed with alizarin. This reveals that the process of immobilization of a natural dye onto ZnO nanoparticles indeed improves the dye properties significantly and opens the way for a wide range of further studies into surface-immobilized dyes.

Abstract
In this work, we report a new octanuclear cluster based on FeIII and the ligand 1H-imidazole-4,5-dicarboxylic acid, [Et3NH]12[Fe8(IDC)12]·10DMF·13H2O (1), with a metal core containing eight FeIII connected by only one type of organic ligand. A peak at 573 m/z in the mass spectra of the compound suggests the adduct species {[Fe8(IDC)12]+8H}4-. By X-ray photoelectron spectroscopy, the oxidation state of the iron cation was confirmed to be 3+, also identifying the presence of a quaternary nitrogen species, which act as a countercation of the anionic metal core [Fe8(IDC)12]12-. Mössbauer spectra recorded at different temperatures show an isomer shift and quadrupole splitting parameters that confirm the existence of only FeIII-HS in the structure of 1. X-ray analysis reveals that compound 1 crystallizes in the orthorhombic system space group Ibam, confirming a molecular cluster structure with an almost regular cube as geometry, with the FeIII atoms located at the corners of the cube and connected by μ-1κ2 N,O:2κ2 N',O‴-IDC3- bridges. Additionally, the magnetic measurements reveal a weak antiferromagnetic coupling in the Fe8 III coordination cluster (J = -3.8 cm-1). To the best of our knowledge, 1 is the first member of the family of cubes assembled with 1H-imidazole-4,5-dicarboxylic acid and FeIII cation, exhibiting high pH stability over a broad pH range, making it an ideal candidate for the design of supramolecular structures and metal-organic frameworks.

Multiscale Study of Interactions Between Corrosion Products Layer Formed on Heritage Cu Objects and Organic Protection Treatments. HERITAGE 2019.

Abstract
In the framework of the protection of copper objects exposed to atmospheric corrosion, different solutions are envisaged, among them carboxylate treatments (HC10). In this study, an analytical approach based on complementary techniques from micrometer to nanometer scale (μRS, SEM-EDS, SAM) is used to describe the properties of the corrosion products layer (CPL) and determine the penetration depth of the HC10 protection treatment inside the CPL of copper samples issued from the roof of the Saint Martin church in Metz. The CPL consists in a thick brochantite layer (20 to 50 μm), mainly composed of Cu4SO4(OH)6, on top of a thinner (1 to 5 μm thick) cuprite layer, Cu2O, acting as a natural corrosion barrier on the metal. Application of the organic treatment is implemented by immersing the corroded samples in HC10 solution, consistent with future requirements for large scale applications. Even for short-term duration (one minute), the HC10 treatment penetrates to the cuprite/brochantite interface, but Cu(C10)2 precipitate is only detected locally, whereas for a longer immersion of thirty minutes, it is present in higher proportions in the whole brochantite layer, filling the pores, up to the cuprite/brochantite interface. Cu(C10)2 acts as a second inner barrier and prevents liquid infiltration.

Abstract
1,2‑Dihydroxyanthraquinone (Alizarin-AZ) is available, low-cost organic compound. Besides, AZ has multiple applications owing to its drawing attention photoactivity. This paper is devoted to study the influence of Gamma irradiation on the morphology, optical, and dielectric properties of AZ nanostructured thin films. Nanostructure powder of Alizarin is synthesized according to chemical routes. Subsequently, thin films of AZ are fabricated via thermal evaporator. The bared thin film is irradiated at different doses of 60Co γ-rays. Furthermore, the bared and irradiated films are characterized via X-ray diffraction (XRD), atomic force microscope (AFM) and UV-Vis-NIR spectroscopy. XRD investigations reveal that the bared film has a nanostructure and the average particle size increases gradually as the γ-irradiation dose increases. AFM images show remarkable increment in the surface roughness of the irradiated film over the bared one. In the light of structure induced changes, clear variations in the optical properties are addressed. Of these, the energy gap decreases gradually as the irradiation dose increases. The film irradiated at 45 kGy shows the highest optical conductivity. Based on our results we suggest AZ nanostructured thin films as potential candidate for optoelectronics devices.

Abstract
Abstract
The Raman effect is at the basis of Raman scattering and microspectrometry: in the first part of the chapter, it is very shortly exposed together with differences with infrared (IR) spectroscopy, and advantages and drawbacks of the technique. The importance of the choice of the excitation wavelength, of the spectrometer (fixed, portable and handheld) and of the optics is underlined, while the information provided by the technique for inorganic and organic materials is considered. The surface-enhanced Raman spectroscopy (SERS) theory and principle applications are also taken into account. In the second part of the chapter, all the different applications of Raman and SERS to cultural heritage materials are contemplated: minerals, gemstones, rocks, patinas and corrosion products, glass, pottery, mortars, dyes, binders, resins, paper, parchment, inks and human remains. For each category of objects, the answers that Raman microspectrometry and SERS can give to the archaeometric and conservation-related questions, the in situ investigations, the search of specific spectral parameters and the use of chemometrics are shown, together with the most recent advances in the field.
