Summary: Unified jet-DBD design (JDBD) proposed in this work generates large-scale plasma in an unbounded region of atmospheric air without gas flow, providing effective exposure to large and complex objects. The JDBD architecture, based on simulations, achieves stable non-thermal plasma source with significant experimental results. By optimizing the electric field and charge distribution, JDBD produces a diffuse discharge in steady air using efficient insulation. The use of a Teflon insulator with a thickness of d(Tf) >= 10 mm results in the formation of an intense and uniform electric field at the open area, leading to a radially/axially expanded plasma jet. Furthermore, the JDBD operates in two distinct states, indicating a mode-swap at 0.8 mA and power dissipation, and exhibits enhanced electric power in reactive mode with small changes in the phase angle.

Summary: This study demonstrates a flexible multi-pin plasma generator with movable electrodes, which can change the shape of the electrode array freely and provide a large-area uniform plasma for treating surfaces of different shapes. The discharge characteristics and sterilization performance of three different electrode configurations are investigated. The results show that the flat-flat and curve-curve configurations yield very similar results, which are much better than the flat-curve configuration. This flexible multi-pin plasma generator offers a simple method for uniformly treating surfaces of different irregular shapes.

Summary: In recent years, there has been a lot of research on oil/water separation using superoleophilic materials and underwater superoleophobic membranes. However, for cleaning up oil slick pollution in near-shore ocean surface, the availability of materials over large areas and fast processing is crucial. In this study, the researchers utilized atmospheric plasma to modify nylon mesh, resulting in superhydrophilicity and underwater superoleophobicity, enabling efficient large-area oil/water separation. This study has the potential to contribute to industrial oily wastewater recovery and oil slicks collection in near-shore water bodies.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
