    Applied spectroscopy is the application of various spectroscopic methods for detection and identification of different elements / compounds in solving problems in the fields of forensics, medicine, oil industry, atmospheric chemistry, pharmacology, etc. 1 Spectroscopic methods. Sample preparation. 2 Analysis of polymers. UV degradation. X-ray absorption spectroscopy has become a common technique in mineral studies only in fairly recent times. It is an element-specific method which is suited to extend structure determination down to the local environment of an atom, i.e. a volume some three orders of magnitude less than that inspected by methods based on X-ray diffraction. However, in line with many other modern techniques, X.

    Manganese oxides with rich redox chemistry have been widely used in (electro)catalysis in applications of energy and environmental consequence. While they are ubiquitous in catalyzing the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR), redox processes occurring on the surface of manganese oxides are poorly understood. We report valence changes at OER- and ORR-relevant Cited by: Areas that are not covered here include time-resolved X-ray probing of 4d and 5d metal systems and of materials for solar energy conversion [2,3], time-resolved X-ray spectroscopy of small molecules and organic systems in solution probing C, N, O and S K-edges [11–13], surface chemical reactions [14–16], femto-, pico- and nanosecond time Cited by: 4.

Highly oxidized metals are constituents of oxidants, reactive intermediates, and materials with interesting conductive and magnetic properties. High-energy spectroscopies have played an important role in identifying and describing the bonding character of highly oxidized metals in these materials.

Grant Bunker, in Encyclopedia of Spectroscopy and Spectrometry, Requirements for X-ray absorption spectroscopy.

X-ray absorption fine structure experiments require energy resolution on the order of several electron volts or less, to resolve modulations in the spectra. Spectra are intrinsically broadened by the ‘core-hole lifetime broadening’, which is an effect stemming from the. X-ray absorption spectroscopy is a powerful spectroscopic technique that is used in a wide range of applications ranging from photochemistry and solar energy conversion [46][47][48] [ X-ray Absorption Spectroscopy (XAS) is a well-established analytical technique used extensively for the characterization of semiconductors in solid or liquid, crystalline or amorphous, bulk or.

Abstract. Moseley () made a systematic investigation of the characteristic x-ray spectra of the elements. The elements investigated were used as targets in x-ray tubes and the radiation from each target was analyzed with the aid of a single crystal : Henry Semat, John R.

We report both experimental and theoretical studies on x-ray absorption measured in the resonant Auger scattering mode of gas phase carbon monoxide near the O1s{yields}2{pi} region.

Both experiment and theory display a crucial difference between the x-ray absorption profiles obtained in the conventional and resonant scattering modes. We review oxygen K-edge X-ray absorption spectra of both molecules and solids. We start with an overview of the main experimental aspects investigation into X-ray absorption spectra book oxygen K-edge X-ray absorption measurements including X-ray sources, monochromators, and detection schemes.

Many recent oxygen K-edge studies combine X-ray absorption with time and spatially resolved measurements and/or operando conditions. The. On one hand, I K- and L 3-edge XANES (X-ray Absorption Near Edge Structure) spectra are presented, showing that while the local structure around the iodate is similar in the two substituted hydroxyapatite lattices, it differs significantly from the one observed in a series of model compounds (NaIO 3, KIO 3, Ca(IO 3) 2 H 2 O).

Due to its elemental specificity and high penetration of the X-rays in the 4–35 keV range, XAS is particularly suited for this, allowing the study of battery materials using specifically developed in situ electrochemical by: 1.

A systematic study of [L 2 Fe 2 S 2] n model complexes (where n = 2- 3- 4-) has been performed using Fe and S K-edge X-ray absorption (XAS) and Fe Kβ and valence-to-core X-ray emission spectroscopies (XES). It is shown that the Fe K-edge XAS data may be used Cited by: 9.

This review highlights the use of the X-ray absorption spectroscopy (XAS) as a local structural tool for selected atoms in several host materials. The main characteristics of XAS to be element-sensitive and its applicability to all states of matter, including crystalline solids and amorphous and liquid states, permit an in-depth study of the structural properties of a large variety of by: The X-ray absorption spectroscopy technique has been applied to study different stages of the lithium/sulfur (Li/S) cell life cycle.

We have investigated how speciation of S in Li/S cathodes changes upon the introduction of CTAB (cetyltrimethylammonium bromide, CH3(CH2)15N+(CH3)3Br−) and with charge/discharge cycling.

X-ray absorption spectroscopy (XAS) and micro-synchrotron based X-ray fluorescence (micro-SXRF) are element specific spectroscopic techniques and have been proven to be valuable tools for the investigation of changes in the chemical environment of metal centres.

XAS allows the determination of the oxidation state, the coordination motif of the probed element, the identity and the number of. A wide range of spectroscopic techniques employ higher-energy electromagnetic radiation, ranging from vacuum UV (≈10−40 eV, −31 nm), including soft X-rays (40− eV, 31− nm), and going to hard X-rays (− eV, − nm) for elucidating molecular structures of chemical and biological interest.

X-ray Absorption Spectroscopy (XAS) has been used on a number of soil science, mineralogy and geochemistry. A high – quality spectra of XAS can be obtained from a small sample of heterogeneous mixtures of gases, liquids and/or solids, which makes this.

X-rays make up X-radiation, a form of high-energy electromagnetic X-rays have a wavelength ranging from 10 picometres to 10 nanometres, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 16 Hz to 3×10 19 Hz) and energies in the range eV to keV.X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays.

Chemical doping of graphene represents a powerful means of tailoring its electronic properties. Synchrotron‐based X‐ray spectroscopy offers an effective route to investigate the surface electronic and chemical states of functionalizing dopants.

In this work, a suite of X‐ray techniques is used, including near edge X‐ray absorption fine structure spectroscopy, X‐ray photoemission. Many biominerals form from amorphous calcium carbonate (ACC), but this phase is highly unstable when synthesised in its pure form inorganically.

Several species of earthworm secrete calcium carbonate granules which contain highly stable ACC.
