“…As the glass cools and anneals, spherical inclusions with diameters in the range of 20 nm to 100 nm are dispersed throughout the glass. This mechanism has been inferred [13] as the source of the red coloration of similar period glasses from Thailand on the basis of the presence of gold in proton-induced x-ray emission (PIXE) spectra, but has not been demonstrated quantitatively. Haslbeck et al [12] explain how a reducing agent such as SnO 2 added to a glass melt along with a gold salt can act as an electron source, reducing the gold to the metallic nanoparticles responsible for red coloration.…”

a b s t r a c tThe Temple of the Emerald Buddha in Bangkok, Thailand is noted for its glass mosaic decorations on exterior walls and statuary. The original mosaic artwork dates to the early 19th century and is composed of variously-colored, mirrored glass pieces. In this work, we examine the chemical composition and optical properties of the red glass manufactured at that time. Through the use of X-ray and optical spectroscopies, we demonstrate evidence that the 19th century craftsmen produced "ruby-gold" glass, wherein the red coloration is caused by the dispersal of nanoscale metallic gold particles throughout the glass matrix.Published by Elsevier Masson SAS.

“…These perturbations were akin to previously reported sperm damage by FeSO4/H 2 O 2 , suggesting that the sites and consequences of oxidative attack on sperm DNA may also be similar. In somatic cells, FeSO 4 /H 2 O 2 has been shown to primarily damage DNA pathway via oxidation pathways [26,45] . And evidence showed that it was also capable of forming free radicals and thereby caused oxidative damage [46,47] .…”

“…The flow-cytometric method based on acridine orange was used to assess the level of sperm DNA damage, as described elsewhere [26] . Briefly, samples were diluted with TNE buffer (0.01 mol/L Tris-HCl, 0.15 mol/L NaCl, 1 mmol/L EDTA, pH 7.4) and transferred into tubes for flow cytometry (Lab test tubes; Beckmann Coulter, USA); 0.4 mL of acid detergent solution (0.08 N HCl, 0.15 mol/L NaCl, 0.1% Triton X-100, pH 1.2) was added, and, after 30 s of gentle agitation, 1.2 mL of acridine orange staining solution (6 μg/mL) was added.…”

“…Raman spectroscopy provides important biochemical information because each molecule has its own vibration pattern that can be used as a "Raman biomarker". Furthermore, these vibrations are usually sensitive to the structure of the molecular environment and can therefore reflect structural change, and the method has been used in a variety of disciplines, including chemistry, physics, biology, biomedicine, engineering, archaeology and biomedical sciences [21][22][23][24][25][26][27] . The Raman spectroscopy has become an ideal technique for the detection of the damage to organs, and in 1984, Raman spectroscopy was, for the first time, employed for DNA extraction from salmon sperm [28] .…”

Oxidative stress is implicated in male infertility and significantly higher reactive oxygen species are detected in 25% of infertile males. Although different agents of various alternative medicines, including traditional Chinese medicine, have been tried with varying success, evidence remains limited on whether and how much herbs or supplements might help increase the anti-oxidant ability of the sperm. This study examined the anti-oxidative effects of icariin, a flavonoid isolated from Herba Epimedii, on the human sperm. We prepared the FeSO4/H2O2-damaged human sperms, which were co-cultured with icariin in vitro, and then observed the changes of the sperm by employing Raman micro-spectroscopy. The results showed that Raman mapping with a 514 nm excitation laser allowed clear differentiation of the nucleus, neck, and, in particular, the mitochondria-rich middle piece of a human sperm cell. The effect of icariin on different organelles of the sperm was quantified by localized spectral Raman signatures obtained within milli-seconds, and icariin could keep the "Raman fingerprint" of the human sperm the same as the control groups, suggesting that icariin could protect the human sperm from being damaged by FeSO4/H2O2. Icariin may serve as a tonifying and replenishing agent of herbal origin for enhancing reproductive functions.

“…Raman spectroscopy allowed for the correlation of some radical molecular ions S 2 − , S 3 − and SO 4 2− , with the color centers and coloration of lapis lazuli. As well, Raman spectroscopy can act as an auxiliary tool to characterize the corrosion products and ancient glass [15,134]. Herrera et al [27] studied the corrosion mechanism of amalgams in antique mirrors of the Andalusian baroque.…”

Both conservation and intervention methods must be compatible with each other and appropriate for the original building materials. Therefore, the characterization of historic building materials is indispensable for investigating chemical composition, micro-structure and morphological features to study the current condition, environmental influence and change mechanism due to natural aging or man-made decay processes. Given the great variety of chemicals which can be analyzed, complex problems related to architectural heritage materials are investigated via optimized methodologies. Among the existing techniques, optical microscopy (OM) is an inexpensive and dominating tool to obtain preliminary information on complex samples. Atomic force microscopy (AFM) can provide real three-dimensional topographies showing sample surface properties. Electron microscopes combined with energy dispersion X-ray analysis (EM-EDX) are the instruments specifically developed to acquire images of target materials at high magnification. Infrared and Raman spectroscopies are frequently used to characterize inorganic and organic compounds. Thermal analysis can rapidly and accurately measure changes in crystalline structure, dehydration and decomposition. X-ray based technologies have a wide range of applications as follows. X-ray fluorescence (XRF) is one of the most frequently used techniques for elemental analysis. X-ray diffraction (XRD) is a fast and inexpensive technique for the characterization of man-made and natural materials. X-ray photoelectron spectroscopy (XPS) is applied to quantify the valence and electronic levels of specific elements. X-ray absorption spectroscopy (XAS) is a powerful technique for detecting the electronic structure of matter. UV-visible (UV-vis) spectroscopy is also of great importance in architectural heritage, which can reveal different physicochemical mechanisms causing color. Laserinduced breakdown spectroscopy (LIBS) can effectively eliminate the pollution on the surface and detect the internal elements of the target material. Ion beam analysis can quantify trace elements with high sensitivity. Mass-based techniques are mainly applied to identify unknown organic substances at the molecular level. This review describes some classical applications of individual techniques and provides scientific support for scientists and engineers to make decisions in the context of architectural heritage.
