Summary: Cold atmospheric plasma generated in helium has been shown to improve the vigor of lentil seeds, reducing germination time significantly. The addition of nitrogen to the helium gas mixture further increases this time saving, while the addition of molecular oxygen does not have a positive impact. The plasma treatment also results in increased hydrophilicity of the seed coating and enhanced water absorption, leading to sustained biological effects and higher vigor in the seeds over time.

Summary: The study achieved the construction of nanostructures on the coating surface by vapor deposition of CeO2 during atmospheric plasma spraying. The backside deposition method was employed to demonstrate the occurrence of vapor deposition and collect pure vapor-deposited nanostructures for improved performance. The effects of high-temperature and high-speed deposition conditions, the high vapor pressure of CeO2, and the agglomerated porous feature of the powder on vapor phase formation were discussed, and the deposition mechanism was revealed. The study also developed the reversible wettability of vapor-deposited nanostructures through vacuum and UV-O3 alternate treatment.

Summary: Dielectric insulators with patterned topographic relief are utilized to spatially define filamentary microdischarges in atmospheric pressure DBD plasmas, enabling localized surface treatment such as etching, micro-texturing, and wettability modification. This approach allows for the generation of arbitrary discharge patterns, anisotropic etching of materials, and spatial patterning of surface properties without the need for lithographic masks. The method provides a user-defined way to pattern DBD streamers for subsequent surface modification, material deposition, or etching.

Summary: In this study, a CeO2 coating with lotus leaf-like bi-scale structures was deposited by air plasma spraying. It was observed that the surface wettability of the coating exhibited a special delayed phenomenon, requiring atmospheric storage for the transition from superhydrophilicity to super-hydrophobicity. The adsorption effect was identified as the main factor influencing the surface wettability, with the coating surface spontaneously adsorbing low surface free energy substances during atmospheric storage, leading to the change in wettability.

Summary: The wettability of ultra-high molecular weight polyethylene surfaces can be modified by atmospheric plasma treatment, decreasing the contact angle from 85 to 40 degrees immediately after treatment and gradually reverting back over 90 days. Although the plasma treatment increases roughness, the surface retains its mirror finish.

Summary: The grim situation of bacterial infection has become a major threat to human health. A new bactericidal method is urgently needed to fight drug-resistant bacteria caused by non-standard use of antibiotics. Cold atmospheric plasma (CAP), composed of various bactericidal species, has shown excellent bactericidal effect on microbes. However, the mechanism of interaction between CAP and bacteria is not completely clear.

Summary: In this study, a DC-APP with air gas was used to activate the surface wettability of Cu substrate in order to improve the solderability issue caused by inherent surface oxidation on IC chips. The plasma treatment resulted in a hydrophilic surface with increased polar component and reduced C-C/C-H content. The solder spreading ratio was improved on the plasma-treated substrate compared to the pristine substrate. After long-term aging, the IMC thickness of the treated sample increased steadily with a ductile breaking mode observed. Additionally, the wettability of SAC305 on the OSP substrate was significantly improved with the application of DC-APP.

Summary: Pyrazolopyrimidinones are core scaffold in many pharmaceutically relevant compounds and have been demonstrated to be efficient in treating several diseases. This study tested the cytotoxic effects of 15 pyrazolopyrimidinones in combination with cold atmospheric plasma (CAP) on glioblastoma U-251MG cell line, and identified two drugs with enhanced cytotoxicity when combined with CAP. These findings suggest the potential of using CAP combined with pyrazolopyrimidinones as a programmable cytotoxic therapy.

Summary: This Letter presents an atmospheric pressure low power microwave-induced air plasma source operating at 2.45 GHz. The device can self-ignite air and generate plasma with only 50 W microwave input power, without any additional trigger. Its sustaining power is as low as 10 W, and the gas temperature of plasma tail flame is about 32 degrees C measured by a fiber optic thermometer. Spectroscopic measurements revealed the presence of strong OH(A(2)S(+)? X-2?) bands at 306-310 nm and oxygen atomic lines O-I (3p5P? 3s5S) at 777.1 nm and O-I (3p3P?3s3S) at 844.6 nm. Furthermore, NO- ?(A(2)S(+)?X-2?(r)) from 200 to 300 nm was also detected in the air plasma jet. This portable plasma apparatus shows potential for air plasma applications in the biomedical fields.

Summary: The purpose of this study was to investigate the effect of cold atmospheric plasma (CAP) treatment on resin nanoceramic (RNC) surface state and its bond strength with resin cement. Different surface treatments were performed on RNC samples, including sandblasting treatment (SB), hydrofluoric acid etching (HF), and plasma treatment of helium gas (CAP-He) and argon gas (CAP-Ar). The results showed that CAP treatment improved the surface wettability and bond strength of RNC, with CAP-Ar combined with silane coupling agent showing the highest bond strength.

Summary: Osteosarcoma is a malignant bone cancer with poor prognosis, partly due to drug-resistant cancer stem cells. Cold atmospheric plasmas and plasma-treated liquids (PTL) have shown selectivity against cancer cells, but their effects on cancer stem cells and in vivo tumor growth are not well understood. This study demonstrates that low doses of PTL promote stemness factors and self-renewal ability of osteosarcoma cells, leading to enhanced tumor growth in vivo. However, combining PTL with a STAT3 inhibitor can suppress tumor growth effectively, suggesting a potential treatment for osteosarcoma.

Summary: Efficient thermal management is crucial for maintaining energy balance and thermal comfort. The design of textiles that can regulate the infrared radiation emitted by the human body is appealing. By coating commercial woven fabrics with poly(N-isopropylacrylamide) hydrogels embedded with submicron-sized silica particles, the reflection of infrared radiation can be increased from 12% to 24% in the 5-15 μm wavelengths range. Further management of the silica particles allows reaching a reflection capacity of 36%. This research opens opportunities for energy-saving heating solutions in enclosed spaces.

Summary: This study aims to develop new fabrics with refreshing feeling, ecological properties, and antimicrobial functions for medicinal applications. Geranium essential oils (GEO) were incorporated into polyester and cotton fabrics using methods like ultrasound, diffusion, and padding. The results showed that ultrasound was the most effective method for incorporating GEO into fabric, resulting in improved color strength, significant antibacterial activity, and stable odor intensity. The textile impregnated with geranium essential oil was suggested as a potential material in cosmetic applications due to its eco-friendliness, reusability, antibacterial properties, and refreshing feeling.
