Summary: This research efficiently utilizes sustainable cellulose nanofibril (CNF) to facilitate the preparation of ultralight, high-porosity carbon nanotube (CNT) hybrid aerogel-based electromagnetic wave (EMW) absorbers. CNF not only acts as a green surfactant to prevent CNT agglomeration, but also functions as a supporting matrix or binder to construct porous CNT-based aerogels. The resulting hybrid aerogels exhibit highly promising EMW absorption performance, outperforming other reported CNT-based EMW absorbers.

Summary: One dimensional carbon nano materials are widely studied for their potential in electromagnetic wave (EMW) absorption. However, their agglomeration and mismatched impedance pose challenges. To address this, we developed a hierarchical architecture by growing amorphous carbon nanotubes (CNTs) on carbon nano fibers (CNF) converted from bacterial cellulose (BC), resembling the structure of pine leaves. This not only solved the agglomeration issue but also enhanced interface polarization capability. The resulting CNTs/CNF composites showed excellent EMW absorption properties with a reflection loss of -68.2 dB and a maximum effective absorption bandwidth of 5.5 GHz.

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.
