Summary: This paper demonstrates the use of plasma-jet printing (PJP) to deposit thermoelectric nanoflakes onto flexible substrates at room temperature, with substantial improvements in material adhesion and flexibility observed. The printed films exhibit electrical conductivity of 2.5 x 10(3) S m(-1) and a power factor of 70 mu W m(-1) K-2 at room temperature. This advancement in plasma jet printing promotes not only the development of energy harvesting but also large-scale flexible electronics and sensors for space and commercial applications.

Summary: The study found that adding a small amount of nitrogen or oxygen to argon can make the plasma channel smooth, while the rotational frequency of the electrode does not affect the appearance of the plasma channel. Optical emission spectra show that adding O-2/N-2 reduces the emission intensity of transitions from excited argon levels to metastable states, leading to a transition of the discharge channel's nature.

Summary: We developed an in silico model to simulate the response of B16F10 melanoma cells to a helium atmospheric pressure plasma jet (APPJ) and doxorubicin drug (DOX). The simulation results showed that increasing plasma duration and DOX concentration resulted in increased cytotoxicity and a higher apoptosis probability compared to mitosis probability. Furthermore, combining plasma treatment and drug application enhanced cell cytotoxicity. This in silico model is valuable in the field of plasma medicine for understanding the response of different cancers to APPJ and cancer drugs.

Summary: The study successfully addressed the issues of flashover performance and stability of high-voltage, high-power FGM-based electric insulation by interfacing rutile and anatase TiO2 layers using atmospheric pressure plasma processing. The FGM showed significant improvements in reducing electric field and increasing flashover voltage, along with exceptional long-term stability. The mechanisms of plasma-enabled graded layer formation were presented, offering potential for precise engineering of FGMs for diverse applications in various fields.

Summary: In this study, a new method for determining both the gas temperature and the air fraction in non-thermal atmospheric helium plasmas is presented. This technique, based on UV-Atomic Emission Spectroscopy and the measurement of collisional broadening of specific emission lines, is particularly sensitive under low gas temperature conditions and suitable for diagnosing cold helium plasmas used in biomedical applications. Quantifying the air content is crucial for understanding the chemistry and clinical effects of these plasmas.

Summary: This study investigated the impact of oxygen impurity on the inlet gas in a nitrogen atmospheric pressure plasma jet (APPJ). A numerical model was developed to simulate the nitrogen APPJ considering fluid dynamics, heat transfer, mass transfer, diffusion, and chemical reactions. Experimental tests were conducted to verify the plasma temperature characteristics on the treated surface. The findings revealed that the plasma temperature decreased with increasing oxygen impurity, affecting the excited and neutral species composition.

Summary: The effects of plasma treatment time on the gas permeation and pervaporation dehydration properties of organosilica membranes were investigated. The study found that increasing plasma modification time resulted in a decrease in pore size, leading to an increased He/N2 permeance ratio. The H2O/EtOH permeance ratio also increased from about 20 to over 1000 as the plasma modification time increased due to changes in pore structure and water adsorption properties.
