Summary: A novel and facile protocol for the fast and autothermal formation of different types of nanocarbons including 3D graphene-like nanosystem via combustion synthesis is presented in this study. The combustion reaction of magnesiothermic reduction of carbon-bearing oxidants resulted in the total conversion to solid raw products containing mostly nanocrystalline magnesium oxide, porous carbon, and layered graphene-related nanomaterial. Purification in mineral acid removed the MgO and non-reacted reducer, enabling efficient recovery of the carbon product.

Summary: High-purity zirconium metal is important in the nuclear and energy industry, but it is difficult to produce cost-effectively due to its strong affinity to oxygen. Powder metallurgy can be used to prepare zirconium metal, and zirconium powder can be obtained by deoxidation of zirconium hydride powder. This study proposed an efficient process using magnesium powder as a reducing agent in a hydrogen atmosphere to prepare high-purity ZrH2. The effect of hydrogen on the reduction and deoxidation of ZrO2 was investigated, and it was found that hydrogen could destabilize Zr-O solution and assist in the preparation of ultra-high pure zirconium hydride powder with low oxygen content and small particle size.

Summary: A scalable study on deoxidation of off-grade titanium sponge using magnesium metal under argon and hydrogen mixed gas was conducted to develop an efficient and cost-effective recycling process. Titanium hydride (TiH2) produced from the hydrogenation of off-grade titanium sponge was used as the feedstock. The deoxidation process was carried out at 933 K for 12 hours using magnesium metal in magnesium chloride and potassium chloride molten salt under argon and 10% hydrogen mixed gas atmosphere. The results showed that the deoxidation of TiH2 using Mg metal under Ar and H-2 mixed gas can significantly reduce the oxygen concentration in off-grade Ti sponge.

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.
