Published: Feb. 7, 2025

Amyloid fibrils are one of the important forms protein aggregates, first discovered in pathological brain tissues patients with various neurodegenerative diseases. They considered core markers different In recent years, research has found that multiple proteins or peptides dynamically assemble to form functional amyloid-like nanofibrils under physiological conditions, exhibiting excellent mechanical properties, high environmental stability, and self-healing ability. Therefore, they have become a class biological nanomaterials development potential. This article systematically reviews latest progress preparation, functionalization, application engineering provides an outlook on possible future directions.

Areca Catechu Biochar and Nano-Biochar as Adsorbents for Congo Red: Synthesis, Characterization, and Performance Evaluation

BULLETIN OF CHEMICAL REACTION ENGINEERING AND CATALYSIS, Journal Year: 2025, Volume and Issue: 20(1), P. 112 - 128

Published: Feb. 10, 2025

The presence of hazardous synthetic dyes such as Congo Red in industrial wastewater poses a significant environmental threat. This study explores the potential biochar (BC) and nano-biochar (nano-BC), derived from Areca catechu husk sustainable adsorbents for dye removal. Nano-BC was synthesised via hydrothermal carbonisation mechanical ball milling, leading to enhanced structural surface properties. X-ray Diffraction (XRD) revealed that Pinang is predominantly amorphous, while BC exhibits increased crystallinity with sharp peaks, nano-BC demonstrates highest nanostructural refinement. Fourier Transform Infra (FTIR) confirmed transformation aliphatic-rich raw biomass into aromatic-dominant structures nano-BC, showing more pronounced graphite-like features. Scanning Electron Microscope (SEM) illustrated morphological evolution, exhibiting refined, uniformly porous structures. BET analysis has significantly higher area 41.38 m²/g smaller pore size 8.4928 nm compared 22.38 15.39 nm, enhancing adsorption capacity. Furthermore, kinetics followed pseudo-second-order model, isothermal monolayer maximum capacity (Qmax = 154.526 mg/g). These findings highlight superior performance emphasising its environmentally friendly water treatment applications.

Adsorption Performance of Fe2O3-Modified Dolomite Composite (DFC) for Congo Red Removal

Water, Journal Year: 2025, Volume and Issue: 17(8), P. 1198 - 1198

Published: April 16, 2025

Printing and dyeing wastewater is known for its high color intensity, complex composition, low biodegradability, making treatment a significant challenge in environmental protection. Dolomite natural mineral with abundant reserves can be effectively used as an adsorbent carrier. In this study, the dolomite loaded by Fe2O3 composites (DFC) was synthesized systematically characterized using XRD, SEM, TEM, BET, XPS, IR to evaluate structural surface properties. The adsorption performance of DFC on Congo Red (CR) then investigated. maximum amount CR 3790.06 mg⋅g−1, removal rate still stable at 97% after five cycles test, which demonstrated that exhibited exceptional efficacy regeneration capability. Fe3+ beneficial improve effect DFC. addition, type adsorption, kinetic calculations were performed, indicated Weber–Morris diffusion modeling study showed behavior influenced interplay many mechanisms. offers innovative method efficient utilization creating renewable materials dye remediation.
