Greenhouse gas emissions altered by the introduction of a year‐long fallow to continuous rice systems

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Rice (Oryza sativa L.) production in California follows a norm of mono‐cropping with little to no rotations or fallows. Both winter droughts, which lead to water restrictions, and spring rains, which inhibit field machinery operations, have resulted in increased fallow frequencies, where no crop is grown during the summer growing season.

XANES spectroscopy proofs pH‐dependent P sorption partitioning to Fe oxyhydroxides versus montmorillonite in acidic soils

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background Fe and Al oxyhydroxides are well‐known phosphorus (P)‐retaining minerals in soils. Little information is available regarding the relevance of clay minerals for the sorption of P in mixed oxyhydroxide–clay mineral systems and pH effects on P sorption partitioning.

Maternal diet and gestational diabetes mellitus modestly influence children's growth during their first 24 months

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective To evaluate whether diet and gestational diabetes mellitus (GDM) during pregnancy influence children's growth during their first 24 months. Methods Growth data of children (n = 378) of women with overweight/obesity were obtained from clinic records (birth, 3, 6, 12 and 24 months), and variables (standard deviation scores (SDS) or ...

Raman Analysis of Roman Mosaics From the Upper Guadalquivir Valley (Spain)

open access: yesJournal of Raman Spectroscopy, EarlyView.
This work is focused on the Raman analysis of two Roman mosaics from Jaén (Spain) using portable and benchtop equipment, complemented by elemental analysis using EDXRF and petrographic analysis. The results obtained have provided a detailed characterisation of the tesserae.

Non‐invasive Analyses of an Etruscan Fibula From Vulci (Italy): The Benefits of a Combination of Micro‐Raman Spectroscopy, 3D Reconstruction Through X‐Ray Microscopy and ED‐XRF With Monte Carlo Simulation

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study analyzed an Etruscan bronze fibula through non‐destructive techniques. The patina and alloy were examined using micro‐Raman spectroscopy and ED‐XRF with Monte Carlo simulations, revealing the formation of corrosion products such as brochantite and sampleite and a binary Cu‐Sn alloy composition.
