High-Performance TiCT-MXene/Mycelium Hybrid Membrane for Efficient Lead Remediation: Design and Mechanistic Insights.

ACS Appl Mater Interfaces

January 2025

Department of Materials Design and Innovation, University at Buffalo, Buffalo, New York 14260-1660, United States.

This study presents a hybrid microfiltration technology designed for high-performance lead (Pb(II)) remediation, especially from aqueous solutions with high Pb(II) concentrations, by utilizing two-dimensional (2D) TiCT-MXene layers deposited on dry mycelium membranes. The hybrid TiCT-MXene/mycelium (MyMX) membranes were fabricated via a single-step electrochemical deposition (ECD) technique, which enabled a uniform coating of 2D TiCT-MXene onto individual hyphal fibers of a prefabricated mycelium membrane. Optimized ECD parameters for high Pb(II) uptake were identified using scanning electron microscopy and energy-dispersive X-ray spectroscopy.

Imidazole Cationic-Bridged Pillar[5]arene Polymer as a Recycle Adsorbent for Iodine Capture.

ACS Appl Mater Interfaces

January 2025

Key Laboratory of Intelligent Supramolecular Chemistry at the University of Yunnan Province, National and Local Joint Engineering Research Center for Green Preparation Technology of Biobased Materials, School of Chemistry & Environment, Yunnan Minzu University, Kunming 650500, P. R. China.

Developing efficient and recyclable iodine adsorbents is crucial for addressing radioactive iodine pollution. An imidazole cation-bridged pillar[5]arene polymer (P5-P5I) was synthesized via a salt formation reaction. P5-P5I exhibited a high iodine vapor capture capacity of 2130.

Valsartan (VST) is an angiotensin II receptor antagonist with low oral bioavailability. The present study developed a solid self-nanoemulsifying drug delivery system (S-SNEDDS) to enhance the oral absorption and bioavailability of VST. VST-loaded liquid SNEDDS (VST@L-SNEDDS) was prepared by investigating the solubility of VST and constructing the pseudo-ternary phase diagrams.

Pesticide contamination in wastewater poses a significant environmental challenge, driven by extensive agricultural use. This study evaluates the removal of chlorpyrifos (CPS) using sugarcane bagasse-based biochar alginate beads in a continuous fixed-bed adsorption column, achieving a remarkable 95-98% removal efficiency. Compared to conventional adsorbents like activated carbon, which typically show CPS adsorption capacities ranging from 50-70 mg g⁻ under similar conditions, the biochar alginate beads demonstrate better performance with a sorption capacity of 91.

Diabetic wounds with chronic infections present a significant challenge, exacerbated by the growing issue of antimicrobial resistance, which often leads to delayed healing and increased morbidity. This study introduces a novel silver-zinc oxide-eugenol (Ag+ZnO+EU) nanocomposite, specifically designed to enhance antimicrobial activity and promote wound healing. The nanocomposite was thoroughly characterized using advanced analytical techniques, confirming its nanoscale structure, stability and chemical composition.
