Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

open access: yesResponsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Addressing Water Scarcity in Agriculture: A Bibliometric Analysis of Hydrogel‐Based Strategies for Drought Resilience and Sustainable Water Management

open access: yesSustainable Development, EarlyView.
ABSTRACT Drought poses a significant threat to agricultural systems worldwide, exacerbating challenges to food security and sustainability. Hydrogels, superabsorbent polymers that can retain substantial amounts of water, have emerged as a promising solution to mitigate the adverse effects of drought. In this integrated bibliometric and narrative review,

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 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.
