It has been universally delineated that the plasmonic metal nanoparticles can enhance the efficiency of photovoltaic cell by increasing the probability of energetic solar photons capturing phenomena using localized surface plasmonic resonance response. In this paper, we developed a novel in-situ simple approach to synthesize noble plasmonic silver nanoparticles (AgNP) from aqueous poly-vinyl-pyrrolidone solution of metal salt using radiolysis of water via synchrotron monochromatic X-ray irradiation without any chemical reducing agent. X-ray irradiation of water produces hydrated electrons , superoxide and atom radicals , which triggers the reaction and reduces metal salt. X-ray radiolysis based synthesis provides the control over the reaction and prevent the formation of secondary products as occurs in case of chemical reduction route. In the previous studies, synchrotron “white” X-rays had been examined for the synthesis of metal nanoparticles, but that technique limits only upto the material synthesis while in this work we explored the role of “monochromatic” X-rays for the production of bulk amount of nanoparticles which would also provide the feasibility of in-situ characterization. Transmission electron micrographs show that the synthesized AgNP appears spherical with diameter of 2–6 nm and is in agreement with the size estimation from uv-vis spectra by “Mie theory”.

“…Contrary to laboratory-based sources where X-ray imaging was the first technique ever used, the development of X-ray imaging with synchrotron sources began rather late in the 1980s when indirect X-ray detectors with high spatial resolution started to become routinely available [4]. Nowadays, hard X-ray beamlines which offer (full-field) imaging techniques within their portfolio are operating around the globe-for example the tomography beamline 8.3.2 at the Advanced Light Source (USA) [5], beamline 2-BM at the Advanced Photon Source (USA) [6], TopoTomo at ANKA (Germany) [7], the Imaging and Medical Beamline at the Australian Synchrotron [8], the BAMline at BESSY-II (Germany) [9], JEEP and I13 at Diamond Light Source (UK) [10,11], SYRMEP at Elettra (Italy) [12], X-ray imaging beamline at INDUS-2 (India) [13], IBL at PETRA3 (Germany) [14], tomocat at SLS (Switzerland) [15], ANATOMIX and PSICHÉ at Soleil (France) [16,17], BL47XU at SPRing8 (Japan) [18] or the future BEATS beamline at SESAME light source (Jordan) [19]. A more detailed overview is available by Rack et al [20], as well as a general introduction on how to access synchrotron light sources by J. McCarthy [21].…”

TomoPress—In Situ Synchrotron-Based Microtomography under Axial Load

et al. 2020

Computed tomography (CT) with hard X-rays is a mature technique that is in regular use to depict the interior of opaque specimens with spatial resolutions up to the micrometre range (microtomography or µCT). Short acquisition times and sophisticated contrast modes are accessible when synchrotron light sources are combined with microtomography—SR-µCT. Both features render SR-µCT as excellent probe to study delicate samples in situ, for example under mechanical load by deploying corresponding sample environments. The so-called TomoPress is such a device available within the public user programme of tomography beamline ID19 of the European Synchrotron Radiation Facility (ESRF). It allows one to study samples under high axial load (up to 500 N) with high spatial resolution up to the micrometer range. Different gauges are installed to allow online monitoring of the applied force. Constant humidity, temperature and wetting are routinely available as well. The article shall outline basic design principles of the press as well as parameters for its utilisation in a descriptive manner. Selected examples underline the potential of the device for such diverse fields as biomedical research, life sciences and materials research.

“…Principles of FTIR analysis: The infrared spectroscopy depicts the interaction of sample with light radiation when electromagnetic waves interact with the polarity of the chemical bonds of the molecules. When there is no polarity in the molecule, the infrared interaction is inactive, and the molecule does not produce an infrared spectrum. SEM using Carl Zeiss Thornwood, MA15/EVO 18 (New York, United States of America) with resolution of 3.0 nm at 30 kV provides information on the surface morphology of GS at the micro level and highlights the crystalline and noncrystalline nature of GS. Synchrotron microtomography (SR‐μCT), a third‐generation synchrotron‐based X‐ray imaging beamline (Indus‐2, BL‐4), has a high sensitivity and fast image capacity, providing excellent insight into the initiation and promotion of the formation of GS, including mapping of the mineral deposition. For interpretation, the images are first reconstructed for computed 2D slice gray images and thereafter to 3D microtomographic images using the Octopus Imaging 3D tomography software (Gent, Belgium). Synchrotron X‐ray fluorescence spectroscopy (SR‐XRF): This interprets the spectra using PyMca software; https://github.com/vasole/pymca.…”

Background and Aim Regional differences in gallstone (GS) composition are well documented in the Indian subcontinent. The reasons for the same are unknown. Etiopathogenesis of GS remains elusive despite advances in instrumentation. This was an in‐depth analysis of the chemical, structural, and elemental composition of GS with special reference to synchroton studies. Methods We used high‐end sensitive analytical complementary microscopic and spectroscopic methods techniques, such as X‐ray diffraction, scanning electron microscopy, Fourier transform infrared, synchrotron X‐ray fluorescence spectroscopy (SR‐XRF), and 2D and 3D synchrotron microtomography (SR‐μCT), to study the ultra structure and trace element composition of three major types of GS (cholesterol, mixed, and pigment). SR‐XRF quantified the trace elements in GS. Results The cholesterol GS (monohydrate and anhydrate) were crystalline, with high calcium content. The pigment GS were amorphous, featureless, black, and fragile, with high calcium bilirubinate and carbonate salts. They had the highest concentration of iron (average 31.50 ppm) and copper (average 92.73 ppm), with bacterial inclusion. The mixed stones had features of both cholesterol and pigment GS with intermediate levels of copper (average 20.8 ppm) and iron (average 17.78 ppm). Conclusion SR‐μCT has, for the first time, provided cross‐sectional computed imaging delineating the framework of GS and mineral distribution. It provided excellent mapping of cholesterol GS. SR‐XRF confirmed that pigment GS had high concentrations of copper and iron with bacterial inclusions, the latter possibly serving as a nidus to the formation of these stones.
