Summary: Anatase TiO2 hierarchically structured microspheres with co-exposed {001}/{101} facets were prepared by a facile one-pot hydrothermal method. The morphology and crystallization of the microspheres were systematically investigated under different reaction temperatures, and it was found that the microspheres exhibited better properties at a temperature of 160°C. Modification of the microspheres with different noble metals (Au, Ag, Cu, Pt, Pd) resulted in significantly enhanced photocatalytic activities, with the Pt-modified sample (TPt) showing the highest activity in the degradation of tetracycline hydrochloride and hydrogen production.

Summary: In this paper, the authors prepared a novel cobalt phosphide wrapped by reduced graphene oxide (CoP/RGO) by simple hydrothermal and phosphating reaction. The introduction of RGO enhanced the conductive loss and polarization loss of materials, resulting in better microwave absorption performance compared to most reported transition metal phosphate-based absorbents. The CoP/RGO composites demonstrated a minimum reflect loss value of -52.60 dB and a maximum effective absorption bandwidth of 5.04 GHz, making it a promising candidate as an absorber material.

Summary: Combining hollow materials with magnetic particles to construct hierarchical structures can enhance microwave absorption properties, but the fabrication of such materials is challenging. In this study, a two-step method is developed to synthesize hierarchically nitrogen-doped carbon hollow microspheres assembled with loose and porous magnetic carbon sheets. The resulting nitrogen-doped carbon hollow microspheres exhibit excellent microwave absorption properties due to their unique structure, achieving a minimal reflection loss of -39.87 dB at a frequency of 7.76 GHz. The computer simulation technology (CST) further confirms the practical applicability of these microspheres.

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.
