Summary: In this study, highly efficient and environmentally friendly carboxylated cellulose silica hybrid adsorbents were developed by combining the advantages of cellulose and silica. The surface property and chemical composition of the hybrid adsorbents were extensively characterized, and the results showed that silica particles were densely deposited on their surface. These hybrid adsorbents demonstrated a high adsorption capacity that was more than 45% higher than that of carboxylated cellulose adsorbent, thanks to their porous structure and large specific surface area. They also maintained a high MB adsorption efficiency of up to 70% even after undergoing five cycles. This research has important implications for wastewater treatments as the cellulose silica hybrid adsorbents offer sustainable and cost-effective alternatives to traditional adsorbents.

Summary: A magnesium-modified biochar was prepared through solvent-free ball milling with a precursor of MgCl2 center dot 6H(2)O. Recyclable biochar beads were then fabricated by introducing sodium alginate and Fe3O4. These beads exhibited excellent adsorption performance for phosphate due to the formation of magniferous crystals on the biochar surface, resulting in accelerated electrostatic interactions and precipitation. The beads also showed excellent magnetism-driven recyclability, avoiding secondary contamination and expanding the application field of the adsorbent.

Summary: The physicochemical and structural characteristics of magnetic materials can be modulated by exposure to a magnetic field, allowing for enhanced adsorption performance. This study prepared Alginate/Polypyrrole/ZnFe2O4 (Alg/PPy/ZnFe2O4) magnetic beads and investigated their adsorption performance for the drugs acetaminophen (ACT) and ibuprofen (IBU) under the influence of an external magnetic field (EMF). The presence of the EMF altered the swelling and pHPZC behavior of the magnetic beads, enhancing their adsorption capacity for ACT and IBU compared to pristine beads (Alg/PPy). The adsorption mechanism followed a pseudo-second-order and the Freundlich isotherm. Additionally, the magnetic beads maintained a high adsorption capacity even after multiple reuse cycles.

Summary: An analytical method using atomic absorption spectrometry coupled to hydride technique with ultrasound assisted acidic extraction was developed for determination of inorganic arsenic species in retorted oil shale slurry. Trivalent arsenic was measured after sample stabilization and reaction with a reducing agent, while total inorganic arsenic was assessed by the pre-reduction of As(V) to As(III) and the difference in concentration between total inorganic arsenic and As(III). The limit of quantification was 3.7 mg kg(-1) for As(III) and 1.3 mg kg(-1) for itAs.

Summary: Responsive materials combining photo-responsive molecules and polysaccharides can be utilized for controlled drug delivery using light as an external stimulus. In this study, a light-responsive hybrid film of Ca2+-cross-linked alginate (ALG) and 3-PtTPyP was developed for drug delivery. The film exhibited light-induced weight loss due to the degradation of ALG matrix by reactive oxygen species generated by the photo-excited 3-PtTPyP, enabling controlled release of hydrocortisone (HC). The hybrid film also demonstrated photodynamic action against mycobacteria strains, suggesting its potential applications in antibacterial photodynamic therapy.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
