Summary: This study demonstrates the efficient removal of cellulose-reactive anionic dyes using water hyacinth root powder (WHRP) bioadsorbent. By adjusting adsorption conditions such as pH, adsorbent dose, dye concentration, particle size, mixing speed, and temperature, the adsorption performance can be effectively enhanced. The adsorption process exhibits spontaneity and exothermicity in terms of Gibbs free energy and enthalpy, and is controlled by multiple mechanisms.

Summary: The study found that using wet pomace treated with laponite for adsorbing Cr(VI) ions resulted in higher efficiency, possibly due to a cooperative interaction between biomass surface and laponite platelets, increasing the accessibility of adsorption sites. Experimental results showed that intraparticle diffusion plays a significant role in the adsorption process, and there is a linear relationship between adsorbent mass and diffusion lifetime.

Summary: The study investigated the co-pyrolysis of food waste with lignocellulosic biomass and found that temperature and the ratio of food waste to wood bark had significant effects on product yields, with nitrogen flow rate having a minor impact. Co-pyrolysis at higher temperatures resulted in more non-condensable gases and less char. By combining food waste and wood bark at a 1:1 ratio at 700°C, the highest hydrogen gas yield and the most significant suppression of harmful compound formation were achieved. The study demonstrates the potential of co-pyrolysis for valorizing biowaste and reducing the formation of harmful chemicals.

Summary: The utilization of lignocellulosic agricultural waste biomass has the potential to provide a carbon net zero solution for the production of valuable chemicals. However, the lack of a selective and efficient catalyst has hindered progress in this area. This study reports the development of a promising catalyst prepared by sulfonation of activated carbon followed by tin (Sn) impregnation. The catalyst demonstrated good performance in converting model carbohydrate mixtures and real apple fruit biomass waste, although stability was lower in the presence of impurities.

Summary: We evaluated the suitability of hazelnut shell for pellet production and found that it has desirable chemical properties. However, fuel agglomeration is complicated due to its chemical and mechanical properties. Our study shows that blending hazelnut shell with pine sawdust in pellet production is feasible, but only at lower percentages. The produced pellets meet industrial and domestic standards, but improvements are needed for mechanical durability and bulk density.

Summary: This study aimed to enhance the bioavailability of rosmarinic acid, a bioactive compound with high anticancer activity, by encapsulating it in tetrasulfide-based porous organosilica nanoparticles. The synthesized nanoparticles were small in size and had a high surface area and an average pore diameter. The nanoparticles showed effective accumulation in cancer cells without toxicity to normal cells. Treatment with rosmarinic acid-containing nanoparticles resulted in significant cell death in cancer cells. Overall, these findings suggest that the synthesized nanoparticles can enhance the pharmacological effects of rosmarinic acid.

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.
