“…Most applications concern the analysis of well-characterized surfaces, such as metal alloys. Analysis of glasses and ceramics, both modern and archaeological, are popular, since the ablated mass is so minimal that the method is considered non-destructive [ 10 - 12 ].…”

Lasers and laser spectroscopic techniques have been extensively used in several applications since their advent, and the subject has been reviewed extensively in the last several decades. This review is focused on three areas of laser spectroscopic applications in atmospheric and environmental sensing; namely laser-induced fluorescence (LIF), cavity ring-down spectroscopy (CRDS), and photoluminescence (PL) techniques used in the detection of solids, liquids, aerosols, trace gases, and volatile organic compounds (VOCs).

“…The XRF method has a great advantage in being a direct non-destructive multi-element analysis of solid-state samples, which results in a significant reduction of analysis time, since no special sample treatment is needed. The possibility of application of mobile XRF systems makes this technique attractive for many purposes [5][6][7]. But in this particular case, i.e.…”

“…It also quickly became a subject of study for their application in basic or bi-functional catalysis, in particular in the synthesis of heavy alcohols with the Guerbet reaction (Tsuchida et al, 2008), the Knoevenagel condensation reaction (Sebti et al, 2002), the Michael addition (Gruselle et al, 2011), or for dehydration (Lan and Zhang, 2015), oxidation (Zhao et al, 2013) or dehydrogenation reactions (Hara et al, 2003). HAPs have the general chemical formula Ca 5 (PO 4 ) 3 OH, but are generally described by the Ca 10 (PO 4 ) 6 (OH) 2 formula, which actually represents two molecules contained in the crystalline pattern (crystalline symmetry, space group 6/m) (Charlton et al, 2006). The composition of the hydroxyapatites is extremely variable, because not only they are rarely stoichiometric (Ca/P = 1.67), but also because each constitutive element can be, to a certain extent, substituted without losing the crystalline structure (Ben Osman, 2014): Ca 2+ ions can be replaced by mono and divalent cations such as Sr 2+ , Ba + , Pb 2+ , Mg 2+ , Zn 2+ , and Na + .…”

One of the most interesting intermediates for the chemical industry is acrylic acid, which can be derived from lactic acid by catalytic dehydration in the gas phase. The realization of this reaction is complex due to a strong thermal activation leading to the formation of undesired by-products (acetaldehyde, propanoic acid…) as well as polymerization. We studied this reaction over hydroxyapatites modified by substitution of the hydroxyl groups by fluoride. This notably enabled increasing the selectivity to acrylic acid while reducing the formation of the undesired acetaldehyde. Introduction of fluoride induced a modification of the phosphate (PO 3− 4) groups. In the presence of water, fluoride prevented the formation of hydrogenophosphate species (HPO 2− 4), which are well-known acid sites responsible for the formation of acetaldehyde by decarboxylation/decarbonylation. Further, we evidenced an important impact of fluoride substitution on crystallinity, specific surface area and on the surface Ca/P ratio. This latter is known to be a key parameter to control the acidity and the basicity of the hydroxyapatites. Using FT-IR spectroscopy with propyne as a probe molecule, we could show that lactic acid was concertedly adsorbed on basic and acid sites, which might be at the origin of the observed superior performances.
