Summary: This study proposes a mechanism to tune the thermal quenching performance of phosphor materials by changing the crystal lattice environment. By replacing with a solid solution, the crystal field splitting energy is decreased and the thermal quenching activation energy is adjusted, leading to increased luminous intensity and band gap value. In addition, a monophase white-emitting phosphor with good thermal stability is successfully prepared, achieving a relative sensitivity of 3.17% K-1 for temperature measurement applications.

Summary: In this paper, a Y4GeO8:Bi3+,Eu3+ phosphor with dual emission centers was synthesized using solid-state reaction technology. The structure, morphology, and luminous properties of the phosphor were investigated, and its potential applications in optical thermometry were explored using fluorescence intensity ratio and thermochromic techniques. The Y4GeO8:Bi3+,Eu3+ phosphor exhibited broadband emission from Bi3+ ions and characteristic emission peaks from Eu3+ ions under 290 and 347 nm excitation. It showed excellent temperature-sensing capabilities, with a maximum relative sensitivity of 1.51% K-1 (λ(ex) = 290 nm). The emitted color of the phosphor shifted from faint yellow to red with a high chromaticity shift (0.180) as the temperature increased from 303 to 513 K, which could be easily distinguished by the naked eye. The results suggested that the Y4GeO8:Bi3+,Eu3+ phosphor has potential applications in optical temperature measurement and high-temperature safety marking.

Summary: Nowadays, multi-mode luminescent thermometry has emerged as a strongly promising noncontact temperature-sensing technique. In this study, three-mode optical thermometry techniques were successfully designed using thermochromic Gd2GaSbO7 (GGS):Bi3+,Eu3+ phosphors. The GGS:Bi3+,Eu3+ phosphors showed remarkable variation in emission color with temperature, and the fluorescence intensity ratio of Bi3+ and Eu3+ provided outstanding relative sensitivity and temperature uncertainty. These discoveries suggest that GGS:Bi3+,Eu3+ phosphors have great potential in multi-mode temperature detection and high temperature warning areas.

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.
