Models of DG‐Carbon Bands in Raman Spectra: Effects of Basis Functions and Initial Values on the Uniqueness and S/N of Fits Obtained for Atmospheric Aerosol Using Automated Methods

Journal of Raman Spectroscopy, EarlyView.
Raman spectra containing D/G features are fit using combinations of basis functions and initial conditions. Fits with two Lorentzian functions converged to a single optimized fit even with variation of initial peak positions. For five‐band fits, sometimes the final fit varied with initial conditions, and constraints on peak center position were ...

The Unfolding Desert: Observed Structural Drying and Projected Aridity Risks in a Brazilian Family Farming Citizenship Territory

Land Degradation &Development, EarlyView.
ABSTRACT Aridification in Semiarid regions is a recurring theme in Intergovernmental Panel on Climate Change (IPCC) reports and has been documented in Northeastern Brazil. This study analyzes the spatiotemporal dynamics of aridification in the Lower São Francisco River “Citizenship Territory” (Sergipe and Alagoas) at a fine spatial resolution (~1 km ...

Copper and zinc isotopic excursions in the human brain affected by Alzheimer's disease

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2020
Introduction Alzheimer's disease (AD) is neuropathologically marked by amyloid beta (Aβ) plaques and neurofibrillary tangles. Little is known about isotopic compositions of human AD brains.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

Mass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...
