Langmuir Adsorption on Fractal Surfaces

Adsorption Science & Technology, 2015
We developed two new methods for analyzing the fractal characteristics of adsorbents. In the first method, the fractal dimension of the adsorbent is determined based on the Hurst index (H) calculated for the random process of development of the Langmuir ...

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

Extraction of Antimicrobial Peptides From Fava Bean Protein Hydrolyzate by Phosphorylated Biochar

Food Safety and Health, EarlyView.
Antimicrobial peptides were extracted by functional biochar in one step. The enriched peptides demonstrated significantly enhanced antibacterial activity. ABSTRACT The extraction of antimicrobial peptides (AMPs) from plant proteins remains challenging due to their low abundance, structural diversity, and the need for mild, efficient, and selective ...

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

Fluorenone and Fluorenemalononitrile‐Tethered Conjugated Microporous Polymers for Efficient CO2 Uptake and Rhodamine B Removal

Macromolecular Rapid Communications, EarlyView.
TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.
