Time-resolved Raman spectroscopy for in situ planetary mineralogy [PDF]

open access: yes, 2010
Planetary mineralogy can be revealed through a variety of remote sensing and in situ investigations that precede any plans for eventual sample return. We briefly review those techniques and focus on the capabilities for on-surface in situ examination of ...

Raman Spectroscopy Techniques and Technology as a Tool in Environmental Water Analysis [PDF]

open access: yesAerul şi Apa: Componente ale Mediului
Although the normal Raman scattering effect is inherently weak in diluted solutions such as environmental waters and dedicated enhancing techniques are already suitable for trace analysis of many harmful compounds, pollutants, toxins, and other species ...

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Quantitative spectroscopic analysis of heterogeneous mixtures: the correction of multiplicative effects caused by variations in physical properties of samples [PDF]

open access: yes, 2011
Spectral measurements of complex heterogeneous types of mixture samples are often affected by significant multiplicative effects resulting from light scattering, due to physical variations (e.g. particle size and shape, sample packing and sample surface,

Molecular Spectroscopy as an alternative for dating Textiles

open access: yesMATEC Web of Conferences, 2015
Ancient linen textiles undergo with time a slow change reflected in their Infrared and Raman spectra. The recording of FT-IR and FT-Raman spectra, that reveals a disappearance of some bands and appearance of other ones during the centuries, enables a ...

Synthesis, structural and spectroscopic characterization of thallium(I) acesulfamate [PDF]

open access: yes, 2015
The new acesulfamate salt, TlC4H4NO4S, was prepared by reaction of acesulfamic acid and thallium(I) carbonate in aqueous solution. Its crystal and molecular structure was determined by single crystal X-ray diffraction methods. The substance crystallizes
