Lithium isotope analysis on the Neoma MS/MS MC-ICP-MS

Journal of Analytical Atomic Spectrometry
Accurate and precise lithium isotopic composition measurements are achieved on the Neoma MS/MS after careful tuning of the prefilter lenses to allow both Li ion beams to pass through unimpeded.

Characterization of zircon reference materials via high precision U-Pb LA-MC-ICP-MS

, 2017
Recent improvements in laser ablation and multicollector (MC)-ICP-MS technology offer higher sensitivity, robust stability, and larger dynamic ranges. Such advances are translated into improved accuracy and precision on U-Pb age determinations, reduced ...

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

Geological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

ICP-MS mérések optimálása mikroanalitikai vizsgálatokhoz

, 2014
Diplomamunkám célja az volt, hogy az ICP-MS mérések eredményeit pontosabbá tegyem, illetve alacsonyabb kimutatási határt érjek el, ezért egy multielemes mintával végeztem méréseket, mely során az üzemeltető szoftver segítségével ...

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...
