Summary: Controlled droplet manipulation using photothermally induced pyroelectric effects on a super-hydrophobic surface allows for versatile functionalities, including droplet deformation, jetting, splitting, and guided motion by adjusting the laser incident angle. The method offers potential applications in remote droplet control, with capabilities for contactless, electrodeless, and precise spatial and fast temporal control. The distribution of pyroelectric charges plays a crucial role in the process, with evenly distributed charges promoting hydrophobic to hydrophilic transitions and localized charges enabling droplet shape control.

Summary: In this study, large-area micro/nanoporous superhydrophobic polytetrafluoroethylene (PTFE) surfaces that can be printed with re-writable charges were fabricated using carbon dioxide nanosecond pulsed laser ablation. The surface charge density (SCD) was well controlled by adjusting the Weber numbers, impact cycles of droplets, and structure thickness of solid surfaces. The saturated SCD was achieved after only five impacts, which is independent of the Weber number. The research findings demonstrate the potential of using the fabricated surfaces for various droplet manipulations, providing insights for the future design of droplet-based microfluidic devices on biocompatible materials.

Summary: The nepenthes-inspired lubricant-infused surface (LIS) is a novel repellent surface with self-healing, self-cleaning, pressure stability, and ultra-slippery properties, and has shown great promise in microfluidics. Recent developments have focused on droplet manipulation on LIS with different mechanisms induced by various external stimuli, such as thermal, light, electric, magnetic, and mechanical force. The properties of the droplet, lubricant, and substrate on LIS determine the droplet condition, and droplet manipulation can be achieved through altering slipperiness, electrostatic force, and wettability. Applications in various fields, including microreactors and microfluidics, have also been discussed.

Summary: By investigating the synergetic effects of laser texturing and super-hydrophobic coatings, this study found that coated groove-textured surfaces (CGSs) exhibit significant anti-friction and wear-resisting properties under low load. The wear resistance of CGSs decreases with increasing texture density. A load of 0.5 N applied on CGSs with a texture density of 10% reduced the friction coefficient and wear loss by 22.3% and 73.5%, respectively, compared to polished steel surfaces (PSSs).

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.
