1.Introduction and methodology
Carbonates are the most important carbon (C) – bearing minerals being key phases in the Earth’s carbon cycle.
The most abundant carbonates in nature are the rhombohedral calcite (CaCO3 - space group R-3c), magnesite (MgCO3 - space group R-3c) and dolomite [CaMg(CO3)2 - space group R-3]. Ankerite [Ca(Mg1-xFex)(CO3)2, 0 ≤ x ≤ 0.7] is isostructural with...
Water at the Earth's surface is believed to be transported into the Earth's interior by hydrous minerals. Until recently, however, hydrous minerals were not thought to persist at the extremely high-pressure conditions of the Earth's lower mantle (e.g., 23-120 GPa). In recent years, hydrous phases such as phase H (MgSiO4H2), pyrite-type FeOOH, and delta-AlOOH have been found to be...
Iron and other trace metals are essential micronutrients for marine phytoplankton. The availability of these minerals varies seasonally and spatially, and one or more metals is the primary limiting nutrient in about one third of the global ocean. Synchrotron x-ray fluorescence spectroscopy (SXRF) enables simultaneous quantification of multiple elements in individual microalgal (phytoplankton)...
For most of my studies and research, I have been doing experiments in different synchrotrons. Synchrotrons are facilities where the main interest is to generate light at different frequencies, from X-ray to IR, and use the light to investigate matter. The main techniques I have worked on, is Fourier Transform InfraRed Spectroscopy and X-ray microscopy and fluorescence. These two techniques...
In the last decades, we have witnessed an unprecedented surge in high-pressure research that has greatly improved our fundamental understanding of materials under high compression. The X-ray investigations of matter under extreme conditions has become one of the major activities at the ESRF and other 3rd generation synchrotron sources. The array of techniques includes X ray diffraction,...
A large fraction of all the meteorites recovered on Earth’s surface are found in Africa. These include carbonaceous chondrites, samples of primitive material from the early Solar System that include prebiotic organic compounds and essential nutrients for the development and sustenance of life. There are also rock fragments from the Moon and from Mars, the latter being the only physical...
The accumulation of metal and their correlation with the rare earth elements (REE) namely Na, Cl, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Cu, Zn, As, Se, Br, Rb, Sb, Cs, Ba, and REE(La, Ce, Nd, Sm, Eu, Tb, Tm, Yb, Lu), Hf, Ta and Th in roots, leaves and grains in O. Sativa Rice are investigated by destructive Instrumental neutron activation analysis and Proton induced x-ray emission. Exploration of...
Introduction
Light sources provide an indispensable resource for probing with atomic-scale precision, the structural properties of nanoscale materials. In these materials where a strong correlation exists between their crystal structures and their electronic, optical, and magnetic properties, structural and chemical probes using synchrotron X-ray diffraction and spectroscopy are critical...

University of Puerto Rico, Rio Piedras Campus
Abstract:
Phytoremediation uses plants to clean up contaminated environments. Plants can help clean up
many types of contaminants, including metals, pesticides, explosives, and oil....
The VLS-PGM beamline at the Canadian Light Source (CLS) is one of the few beamlines in the Americas that is built to optimize the delivered flux below 250eV, and it is capable of performing X-ray absorption spectroscopy (XAS) at Lithium (Li) and Boron (B) K-edges, and Sulfur (S), Phosphorus (P), Silicon (Si) and Aluminium (Al) L-edges with two dedicated endstations and a suite of...
Status of Hefei light source II, a recently constructed IR-FEL, and the new 4th generation diffraction limited storage ring
The Finnish Synchrotron Light Source Community presents an overview of their community, its science and their roadmap towards a light source
1. Introduction
Perovskite crystallization has not been understood well to date, due to over emphasis on their efficiencies, especially the triple cation-mixed halide compositions. In addition, the difficulty in measuring the critical nucleus sizes in the range of 100 to 1000 atoms shies most experimental method researchers. Synchrotron radiation-based X-ray techniques allow structural...
