Article Abstract
In the last decade, adsorption has been used to minimize the pollution caused by dyes, which represents a serious environmental problem. In this context, this work reports the preparation of phthalic anhydride-modified cellulose (PhCel), through the reaction of cellulose (Cel) with phthalic anhydride (Ph). The efficiency of the reaction was observed by elemental analysis, Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and thermogravimetry/derivative thermogravimetry (TG/DTG). The adsorbent matrix (Cel and PhCel) was used in the removal of crystal violet (CV) and methylene blue (MB) dyes in aqueous medium. In the kinetic study, the experimental data obtained had the best fit to the pseudo-first-order model. In general, the isotherms obtained at different temperatures had a best fit to the model proposed by Langmuir, and the CV and MB adsorption process in adsorbent matrixes can be favored strictly by hydrogen bonds and/or electrostatic interactions for Cel and electrostatic interactions for PhCel.

Microbial contamination of absorbable collagen membranes used in guided bone regeneration (GBR) may compromise healing outcomes. This study aimed to investigate whether the minimum inhibitory concentration (MIC) of hydrogen peroxide (HO) can improve the antibacterial effect of indocyanine green (ICG)-mediated antimicrobial photodynamic therapy (PDT) on absorbable collagen membranes while reducing the need for high HO concentrations. A laboratory-based model was developed using Streptococcus sanguinis and Staphylococcus aureus.

In this paper, lignin was chemically extracted from fibers and modified with branched polyethyleneimine (BPEI) and the resulting samples were applied for the adsorption of two anionic dyes; Acid red 183 (AR183) and Acid blue 25 (AB25) from aqueous suspension. Analytical characterization methods including SEM, FT-IR, TGA/DTG, and XRD were used to analyze the studied samples. The images of the extracted lignin displayed a rough feature.

The increasing pollution of water bodies from various industrial wastewater discharges has raised significant environmental concerns because these effluents contain toxic, nonbiodegradable compounds that pose serious risks to living organisms. In particular, the textile and pharmaceutical industries routinely use dyes that severely degrade water quality and lead to significant environmental issues. Therefore, effective removal of these dyes from industrial wastewater is crucial for mitigating pollution.

In recent years, fluorescence-switchable molecules have garnered significant attention as fluorescent dyes for super-resolution fluorescence microscopy, which is increasingly demanded in the field of biochemical imaging. Among such molecules, diarylethene-S,S,S',S'-tetraoxide derivatives have proven particularly promising due to their ability to achieve high contrast fluorescence switching. Diarylethenes incorporating perfluorocyclopentene as the ethene bridge have become the standard scaffold due to their excellent fatigue resistance and thermal stability.

Structurally colored colloids, or photonic pigments, offer a sustainable alternative to conventional dyes, yet existing systems are constrained by limited morphologies and complex synthesis. In particular, achieving angle-independent color typically relies on disordered inverse architectures formed from synthetically demanding bottlebrush block copolymers (BCPs), hindering scalability and functional diversity. Here, we report a conceptually distinct strategy to assemble three-dimensional inverse photonic glass microparticles using amphiphilic linear BCPs (poly(styrene-block-4-vinylpyridine), PS-b-P4VP) via an emulsion-templated process.
