Summary: Xanthate-modified cross-linked chitosan (chitosan-SH) was synthesized by hydrothermal method for the removal of ruthenium [Ru(III)] from aqueous solutions. The adsorption process by chitosan-SH was found to be fast, reaching equilibrium within 30 minutes with a removal percentage of 94.7% at pH 7.0. Parameters like pH, contact time, initial Ru(III) concentration, solution volume, and adsorbent concentration were investigated to understand their effects on adsorption capacity, showing potential application of chitosan-SH as an adsorbent for Ru(III) in wastewater treatment.

Summary: This study presents a novel magnetic hybridized aerogel for efficiently removing heavy metals from wastewater. The hybrid aerogel, with a slit-like porous structure and numerous exposed active sites, exhibits high adsorption capacity for metal ions. The adsorption process is primarily attributed to monolayer chemical adsorption, and the hybrid aerogel shows higher adsorption affinity and preferential selectivity for Pb2+. The study also highlights the fast magnetic responsiveness and easy recovery of the hybrid aerogel.

Summary: This research uses surface plasmon resonance spectroscopy to explore the real-time adsorption of different OBAs on different cellulose surfaces. Four independent mechanisms governing OBA-cellulose interactions were identified, including surface polarity, OBA solubility, ionic strength during adsorption, and the presence of bivalent cations like Ca2+. These results can be applied for process optimization in related industries and for testing novel OBAs.

Summary: The study focused on the design of chitosan xanthate and cellulose xanthate sponges for efficient removal of methylene blue and Congo red dyes. The sponges exhibited high adsorption capacities and the mechanism was identified as a spontaneous physical sorption process that fitted well with the pseudo-second-order and Langmuir isotherm models. These results suggest that xanthated chitosan/cellulose sponges are effective adsorbents for dye removal.

Summary: This study compared the adsorption of different synthetic dyes on chitosan cryogel beads and analyzed the impact of solution pH on adsorption capacity. The biosorbent was characterized by SEM, BET method and FTIR. Results showed that the adsorption process is mainly regulated by physisorption and amino groups participate in the adsorption process, with Blue 1 > Red 2 > Yellow 5 being the order of adsorption capacity.

Summary: The adsorption behavior of 2-naphthalenethiol and methanethiol on 13 different metal oxide nanoparticles was investigated, with adsorption observed only on ZnO, TiO2, and In2O3. Density functional theory calculations and experimental results are generally consistent, indicating that the adsorption mechanism is related to the relative strengths of metal-sulfur and metal-hydroxyl bonds.

Summary: A porous and amino-rich cellulose-based composite adsorbent (PEI-PCS) was successfully prepared by covalently cross-linking polyethyleneimine on delignified corn straw. The as-prepared adsorbent exhibited universality, rapid adsorption behavior, high adsorption capacity, and good durability. The adsorption process followed pseudo-second-order dynamics and the Langmuir isotherm models. This study provides a sustainable pathway for the manufacture of efficient biomass-based adsorbents and confirms the promising material for the treatment of heavy metal ions.

Summary: In this study, xanthate modified bio-sorbents prepared from corn cob and chestnut shell effectively removed Pb(II) from aqueous solutions. The adsorption process was influenced by factors such as pH, reaction time, temperature, and initial concentrations. The bio-sorbents displayed high selectivity to Pb(II) over Cu(II) and Cd(II), and had great potential for practical applications in treating heavy-metal contaminated surface water.

Summary: This study investigated the flame-retardant effect of transparent epoxy coating with aluminum hypophosphite nanoparticles on polylactic acid sheets. The addition of these nanoparticles into the epoxy resin accelerated the degradation of the coating, resulting in increased char residue. The presence of the nanoparticles reduced the peak heat release rate significantly, leading to the formation of a homogeneous char layer with a 15 wt.% nanoparticle content. However, further increase in content did not enhance the flame-retardant properties due to the formation of structural cracks in the coating.

Summary: Due to their sessile nature, plants are unable to escape from stress factors in their environment, such as high levels of soil cadmium (Cd), which can cause heavy metal stress and impair agronomic performance. In order to mitigate the adverse effects of Cd stress, researchers have explored the use of novel nanoparticles, such as polyamines and carbon quantum dots. In this study, the researchers successfully synthesized a nanomaterial called Put-CQD NPs and found that it could enhance the performance of grapevines under Cd stress conditions.

Summary: Paclitaxel (PTX), the most important member of the taxane family, is used to treat a wide range of cancers but is limited by its low solubility and permeability. In order to overcome these limitations, PTX is formulated with Cremophor EL and dehydrated ethanol as Taxol (R). Alternative PTX formulations based on polysaccharides have been developed in recent years due to the adverse side effects of the current formulation. This review focuses on the recent advances in polysaccharide-based PTX formulations.

Summary: In 2019, Flame Retardancy Index (FRI) was introduced as a universal index for classifying flame-retardant polymer materials. FRI quantifies the flame retardancy performance on a logarithmic scale based on peak Heat Release Rate (pHRR), Total Heat Release (THR), and Time-To-Ignition (t(i)) from cone calorimetry data. It has proved to be reliable for ranking polymer materials in terms of flame retardancy performance over the past four years. Additionally, new variants and the Flammability Index (FI) based on Pyrolysis Combustion Flow Calorimetry (PCFC) data were defined to further analyze the relationship between FRI and FI.

Summary: The packaging of food plays a crucial role in preserving food quality, but traditional packaging systems are inefficient. Cellulose has been widely used as a packaging film material, but lacks antioxidant and antimicrobial activities. Active cellulose-based packaging films have been developed by incorporating antioxidants and antimicrobial agents. This review explores the latest research on the fabrication of these films using natural extracts, polyphenols, nanoparticles, and microparticles, and discusses their effects on film properties.
