A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.

Pyro-expanded black slate in sculptural art Ardósia piroexpandida em arte escultórica

open access: yesCerâmica, 2013
Black slate transformed through a pyroplastic process named pyro-expansion or exfoliation has been explored in the present work in order to be used as sculptural material. Black slate is a highly fissile, fine grained and organic matter rich rock that is

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1451-1463, June 2026.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Evaluating the sustainability of mineral water consumption using multi‐scale hydrogeophysics in Caxambu, Brazil

open access: yesNear Surface Geophysics, Volume 24, Issue 3, Page 234-251, June 2026.
Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Double parton scattering and 3D proton structure: A Light-Front analysis

open access: yes, 2016
Double parton scattering, occurring in high energy hadron-hadron collisions, e.g. at the LHC, is usually investigated through model dependent analyses of the so called effective cross section $\sigma_{eff}$.

Volcanic eruptions from ghost magma chambers [PDF]

open access: yes, 2008
Recent studies have proposed that magma reservoirs crystallized to a virtually rigid crystal-mush can be partially remelted by diffusion of hot fluids. We show that for a crystal mush with the composition of a K-trachyte from the Campanian Ignimbrite (CI)

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...
