Summary: This study focuses on the numerical investigation of dielectric barrier discharge in atmospheric pressure CO2 in a coaxial reactor. Using a numerical model based on the drift-diffusion theory and considering gas heating in a self-consistent manner, the study examines the influence of gas heating on discharge properties and CO2 decomposition across a wide range of applied voltage amplitudes and frequencies. The calculations indicate that neglecting gas heating by assuming a constant (room) gas temperature leads to a significant overestimation of CO2 conversion.

Summary: This article reports a double-mode argon planar plume, which operates in the streamer mode and transits to the filamentary mode. Discharge characteristics and plasma parameters are compared for the two modes, showing that the streamer mode and the filamentary mode correspond to pulsed and humped discharges respectively. Fast photography reveals that the streamer-mode plume is composed of stochastically branching streamers, while the filamentary-mode plume results from a series of moving filaments similar to those in barrier discharge. The filamentary mode has lower excited electron temperature and vibrational temperature, whereas higher electron density and gas temperature, and it achieves better hydrophilicity of polyethylene terephthalate surface.

Summary: The plasma characteristics in a DBD device with a rotating dielectric barrier were investigated in this study. The results showed that rotating the barrier improved discharge power and the number of current pulses. The rotation reduced the grayscale standard deviation of the discharge images and resulted in a diffusion distribution of microdischarges. The mechanism of enhancing discharge energy and uniformity was analyzed based on surface charges and electron detachment from space negative charges.

Summary: The novel GLDBD reactor was designed to efficiently degrade PFOA with removal efficiencies over 98.0% within 50 minutes and energy yields exceeding 114.5 mg.kWh(-1). Reactive nitrogen species were identified as crucial for PFOA degradation in the plasma system, making the reactor less sensitive to various water matrices and promising for practical application. The research proposed possible PFOA degradation pathways based on LC-MS results and DFT calculation, providing an effective and versatile alternative for PFOA removal from different water matrices.

Summary: The characteristics of barrier gas discharge in helium at atmospheric pressure under pulsed excitation conditions were investigated. It was found that increasing the steepness of the excitation pulses had little effect on the discharge current value, but allowed the maintenance of volumetric nature of the current flow. The maximum discharge current was restricted by increased ionization.

Summary: This paper presents a theoretical and conceptual framework for determining the static breakdown inception thresholds in quasi-uniform gas gaps bounded by dielectric layers. It includes the special case of uncoated metallic electrodes and provides a review of breakdown mechanisms and the applicability of associated criteria. The results show a parametrization of the partial discharge inception voltage for wedge-shaped air gaps and propose a physically motivated parametrization of the ionization threshold. These findings are supported by literature data and own measurements.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.

Under optimized conditions, the PER-E-CRISPR assay exhibits a linear range from 10-13 to 10-7 M and a limit of detection of 30.2 fM. The biosensor shows excellent performance in actual plasma, indicating promising prospects for miRNA detection in molecular diagnosis.

Summary: Molecular docking (MD) analysis is widely used for studying the interaction between aptamers and small molecules. This study established steady-state aptamers of tertiary structures (SATS) using specific aptamers of tetracycline antibiotics as docking models. Molecular docking results revealed multiple binding sites in the SATS of aptamers, with significant variations in binding free energy (BFE) and docking score (DS). The study also proposed a method for MD analysis based on SATS, providing insights into binding mode and predicting binding sites.
