Impact of Acid Dopants (HCl vs. H2SO4) on the Structure, Performance, and Reusability of Bio‐Based Luffa/Polyaniline Composites for Methylene Blue Adsorption

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
Evaluation of the impact of acidic dopants (HCl vs. H2SO4) on bio‐derived luffa/polyaniline composites for methylene blue adsorption. Sustainable and low‐cost Luffa cylindrica/polyaniline (LC/PAN) composite adsorbents were developed for the removal of methylene blue (MB) from aqueous solutions. The effect of acid dopants (hydrochloric acid and sulfuric

Trace Metal Biogeochemistry in the Nordic Seas: Arctic and Atlantic Water Inflows Determine (Micro)Nutrient Availability

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract We present a data set of macronutrient and dissolved and total dissolvable trace metal concentrations collected in June 2012 across the Nordic Seas. Surface water and depth profiles of manganese, iron, cobalt, nickel, copper, zinc, phosphate, silicic acid, and NOx (nitrate + nitrite) reveal how warm saline Atlantic waters and cold fresh Arctic

Impacts of Climate Change on Groundwater Quality in the Northern Atlantic Coastal Plain: A Review

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT This review integrates hydrogeological and geochemical processes to assess the impacts of climate change on groundwater quality in the Northern Atlantic Coastal Plain (NACP). Projected changes in air temperature, precipitation, and sea‐level rise are expected to influence groundwater recharge, discharge, storage, and seawater intrusion in ...

Breathable Graphene Oxide‐Polymer Composite Membranes With Two‐Step Barrier Mechanism Against Nerve Agents

open access: yesAdvanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.

Relationship of Dye Adsorption Onto Biomass Activated Carbon Mixed Matrix Ultrafiltration: A Mass Transfer Model Study

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
This study explored dye molecule adsorption from water, focusing on activated carbon in polymer membranes for purifying low‐quality water. Polyvinylidene fluoride (PVDF) membranes showed enhanced removal efficiency of methylene blue (MB) from 89.29% to 98.33% with biomass‐activated carbon (BAC).
