Summary: This study focuses on the design, additive manufacturing, and characterization of porous carbon-based structures with outstanding mechanical properties and oxidation resistance, combined with good electrical and thermal conductivity. Graphite-carbon black powders were 3D printed using binder jetting to create computational models of three different topologies and geometric porosities. The parts were then densified using infiltration and pyrolysis with furan resin. The resulting composite materials exhibit excellent mechanical properties and high oxidation resistance, making them suitable for applications such as Joule resistors and seasonal thermal storage.

Summary: As the energy shortage intensifies, improving energy efficiency and reducing energy consumption have become crucial. In this study, a form-stable composite phase change material (FCPCM) consisting of modified expanded graphite (MEG) and eutectic hydrate was designed as a reliable and efficient thermal energy storage medium. The MEG, constructed by dip-coating of nano ZrO2 sol on the surface of expanded graphite (EG), exhibited improved hydrophilicity and compatibility with the eutectic guest, resulting in faster and larger adsorption rate and capacity. The FCPCM showed a good phase transition temperature, high phase transition enthalpy, and excellent anti-leakage behavior, making it a potential application in solar phase change heat exchangers.

Summary: Facile electrochemical oxidation and functionalization with amine moieties are used to produce rigid framework materials in graphite oxide, enhancing cyclability in adsorptive and electronic applications. A balanced aromaticity in the intercalating amine species is found to facilitate homogeneous distribution throughout graphite flakes while increasing interlayer spacing. High nitrogen abundance leads to successful resolution of turbostratic domains, with results corroborating C-13 MAS NMR findings.

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.
