Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Natural Micronised Clinoptilolite and Clinoptilolite Mixtures with Urtica dioica L. Extract as Possible Antioxidants

Food Technology and Biotechnology, 2004
In this study the in vivo effect of natural micronised clinoptilolite and clinoptilolite forte (clinoptilolite + 40 % extract of pulverised dried leaves of Urtica dioica L.) on the lipid peroxidation and antioxidative capacity in mice was examined.

Optimization and predictive modelling of biodiesel production from waste cooking oil catalyzed by blast furnace slag geopolymer using RSM and machine learning

The Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 6-30, January 2026.
Abstract Biodiesel production from waste cooking oil (WCO) has emerged owing to growing interest in sustainable energy sources. Geopolymers synthesized from industrial wastes, such as blast furnace slag (BFS), are promising catalysts because of their environmental benefits and catalytic properties.

Removal of ammonia by clinoptilolite [PDF]

Global NEST Journal, 2013
The important advantage of zeolite applied to water treatment is its high porosity when comparing to other minerals. The porosity results in good hydrodynamic properties (the increase in the pressure loss on the zeolite filters is 1.5-2.0 times smaller than in the case of sand filters) and adsorption roperties, and in turn high capacity which allows

Preliminary Evaluation of Natamycin‐Incorporated Alginate–Gelatin Membranes as Antifungal Wound Dressings: Physical, Antimicrobial, and Cytotoxicity Analyses

Advances in Polymer Technology, Volume 2026, Issue 1, 2026.
This study investigated the preparation of sodium alginate (ALG)–gelatin (GEL) composite membranes containing natamycin (NA) for use as antifungal wound dressing. Membranes with different concentrations of NA (0, 100, 200, 500, and 1000 ppm) were fabricated through the solvent casting method and then cross‐linked using calcium chloride.

Review and Integrated Framework for Deep‐Sea Mineral Resources, Ecological Influence, and Future Development

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
As global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

Structure investigation of nano-FeO(OH) modified clinoptilolite tuff for antimony removal [PDF]

, 2017
Biomimetic sol-gel synthesis was used to prepare new FeO(OH) zeolite (clinoptilolite tuff) adsorbent effective for antimony removal. The product was compared with other on the market accessible natural or commercial adsorption materials like granulated ...
