Summary: Photoluminescent-carbon nanoparticles (PL-CNPs) have attracted significant interest due to their distinct characteristics, including photoluminescence, high surface-to-volume ratio, low cost, ease of synthesis, high quantum yield, and biocompatibility. They have been extensively studied for their utility in various applications such as sensors, photocatalysts, bio-imaging probes, and optoelectronics. However, some PL-CNPs face limitations in their properties and selectivity, hindering their widespread application. To overcome these challenges, researchers have focused on developing new PL-CNPs with better properties and selectivity using different composite combinations. This review discusses the recent advancements in synthetic strategies, doping effects, photostability, biocompatibility, and applications of PL-CNPs in sensing, bioimaging, and drug delivery, as well as their limitations, future directions, and potential applications.

Summary: Blue phase liquid crystals (BPLCs) have significant potential as next-generation candidates for liquid crystal displays (LCDs), but they suffer from low brightness and energy efficiency due to the need for an extra backlight device. Carbon dots (CDs), a novel fluorescent carbon nanomaterial, were synthesized and introduced into BPLCs to create photoluminescent blue phase liquid crystals (CDs-BPLCs) with self-photoluminescence. CDs not only improve the stability of BPLCs, but also enhance their optical properties. This research opens up possibilities for the development of novel energy-saving display devices.

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.
