Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Cytotoxic and Genotoxic Effects in Buccal Cells of Sandstone Quarry Workers

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Mineral extraction poses significant occupational health risks, particularly from respirable crystalline silica exposure. Sandstone quarrying generates substantial dust, yet evidence of its genotoxic effects remains limited. This study investigated cytogenotoxic damage in sandstone quarry workers from southern Brazil using the buccal ...

Betaine‐, xylitol‐, and extra virgin olive oil–based toothpaste modulates inflammation and oral nitric oxide pathway: Clinical trial in gingivitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Gingivitis is a prevalent and reversible inflammatory condition driven by microbial dysbiosis. Beyond plaque control, interest has grown in oral hygiene formulations capable of modulating inflammation while preserving key microbial functions. Extra virgin olive oil (EVOO), together with xylitol and betaine, has demonstrated clinical

Long‐Term Corrosion of Carbon‐Steel Casing Used in Deep Geological Radioactive Waste Repository

open access: yesMaterials and Corrosion, EarlyView.
Fifty mots 6‐year study of carbon steel corrosion in a deep geological repository (Bure, France). Three corrosion patterns were identified, driven by local conditions. Minimal corrosion layer thickness growth suggests limited corrosion progression under most conditions.

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

open access: yesPolymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...
