Ultraspectral UV polychromator for SRS-isotopic sensor
Journal of Physics: Conference Series, 2019 Abstract We have developed a spectral module for the selection of narrow characteristic spectral lines of isotopes in the ultraviolet Raman spectral channel. To allow resolving closely spaced isotope lines in the continuous input radiation spectrum, extremely high resolution λ / Δλ = 1000 is implemented.

Synergistic Co‐Doping of Barium and Cobalt Enables Stable and Active RuO2 for Acidic Water Oxidation
Angewandte Chemie, EarlyView.Achieving high activity and long‐term durability with non‐iridium catalysts for the acidic oxygen evolution reaction (OER) remains a challenge. This work presents a co‐doping strategy that incorporates Ba and Co into home‐made RuO2, which introduces lattice strain and favorable electronic structure regulation, thereby enhancing both activity and ...

Natural Clinopyroxene Reference Materials for in situ Sr Isotopic Analysis via LA-MC-ICP-MS
Frontiers in Chemistry, 2020 Clinopyroxene is a major host mineral for lithophile elements in the mantle lithosphere, and therefore, its origin is vital for constraints on mantle evolution and melt generation. In situ Sr isotopic measurement of clinopyroxene has been available since

Reconstructing seasonality through stable-isotope and trace-element analyses of the Proserpine stalagmite, Han-sur-Lesse cave, Belgium : indications for climate-driven changes during the last 400 years [PDF]
, 2020 Fast-growing speleothems allow for the reconstruction of palaeoclimate down to a seasonal scale. Additionally, annual lamination in some of these speleothems yields highly accurate age models for these palaeoclimate records, making these speleothems ...

Advanced Functional Materials, EarlyView.A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

A Tracer Diffusion Study of Diverse Photo‐Ionic Phenomena in Strontium Titanate
Advanced Functional Materials, EarlyView.Two strong interfacial photo‐ionic effects are demonstrated for the model system SrTiO3 through the application of isotope exchange experiments: UV illumination is found to enhance the oxygen surface exchange coefficient by several orders of magnitude and to depress the surface space‐charge potential substantially.
