Summary: This work develops a simple and mild strategy to synthesize highly and homogeneously distributed TiO2 nanoparticles on a cellulose template by controlling the cellulose crystallinity. The presence of carboxyl groups on crystalline cellulose restricts the distribution and crystallization of TiO2 nanoparticles. The amorphous TiO2 nanoparticles on cellulose with the highest degree of crystallinity exhibit the highest adsorption capacity, attributed to oxygen defects caused by Ti3+ species.

Summary: A novel cellulose phosphonate/polyethyleneimine composite (MCCP-PEI) with abundant nano-porous structure, strong chelating sites, and excellent hydrophilicity was successfully prepared. MCCP-PEI showed rapid adsorption of Cu(II) and Pb(II) heavy metal ions and exhibited saturated adsorption capacities of 250.0 and 534.7 mg center dot g- 1, respectively. The adsorption mechanism was found to be chemical complexation and electrostatic attraction, with the phosphonate group playing a key role.

Summary: This study investigates the use of nano-TiO2 for remediating arsenic and lead-contaminated rice seedlings. The results show that 1000 mg/L of nano-TiO2, particularly with a rutile structure, significantly reduces the accumulation of arsenic and lead in rice plants and increases their retention in the root iron plaque. Additionally, the effectiveness of arsenic uptake inhibition is dependent on the structure of the nano-TiO2, while lead uptake inhibition is relatively consistent.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
