Summary: This study investigated the redox activity of Graphene quantum dots/TiO2 (GQDs/TiO2) hybrid during water treatment under visible light irradiation. The introduction of oxygen vacancy (V-o) in TiO2 was found to expedite charge transfer and enhance the photocatalytic activity. The findings suggest that the presence of V-o induces visible light excitation, quick charge separation, and effective transmission between GQDs and TiO2, resulting in improved performance in Cr (VI) and RhB removal system.

Additionally, the material could undergo restacking during Cr(VI) removal, leading to enhanced sorption capacity. At higher reaction temperatures, the material showed improved Cr(VI) removal efficiency, making it suitable for treating industrial wastewaters with elevated temperatures.

Summary: A completely non-invasive method for cell manipulation is proposed by combining a microcapillary microfluidic device and an optical fiber tweezer. Chlorella cells inside the microcapillary channel are successfully trapped and manipulated by an optical fiber probe located outside of the microcapillary, making the process completely non-invasive. The curved walls of the microcapillaries act as a lens to enhance light focusing and trapping efficiency.

Summary: Researchers demonstrate the use of graphene quantum dots (GQDs) as downconverters to extend the UV detection range of Si photodiodes to 300 nm and enable distinct visible response to UV excitation. Stable nitrogen functionalized GQDs exhibit high photoluminescence quantum yield, strong UV absorption, and large Stokes shift. A Si photodetector externally sensitized with visible-blind GQDs shows a scalable threefold improvement in UV response and enables bare-eye recognition of UV sub-bands when B- and R-GQDs are combined in tandem.

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.
