Summary: The plasma distribution and density in single glow and double glow hollow cathode discharge were investigated through experiments and simulations based on the two-dimensional fluid model, and the effects of key parameters on plasma density, electron temperature, and potential field were explored. It was found that the high plasma density is caused by the hollow cathode effect (HCE). The critical pore diameter for generating HCE was determined to be the sum of the plasma sheath thickness and four times the electron-neutral mean free path in single glow discharge, while twice the plasma sheath thickness and four times the electron-neutral mean free path in double glow discharge. The HCE in double glow discharge can be observed when the ignition voltage meets the condition of the source cathode voltage being 250 V greater than the workpiece cathode voltage with a PD value of about 1.5 to 3.8 Torr·mm.

Summary: The C12A7 hollow cathode is expected to lead a new generation of hollow cathodes due to its low work function and chemical stability. This study investigated the performance of the C12A7 hollow cathode at different working currents, ranging from 1 A to 20 A, in order to reduce issues caused by overheating. The results showed that the C12A7 hollow cathode performed well at low currents, but exhibited instability at high currents. Simulation results suggested that increasing the cathode orifice size can help reduce the risk of overheating. However, the short lifetime of the C12A7 hollow cathode under high-current conditions makes it difficult to apply in practical scenarios.

Summary: This study investigates the air plasma jet produced by MHCD and finds that the length of the plasma jet is proportional to the air flow rate. Two plasma bullets are formed during the positive pulse voltage off, with a propagation velocity similar to that of the air flow.

Summary: Helium plasma jets generated by micro-hollow cathode discharge (MHCD) with the square-wave power source of different polarities are investigated. The effects of positive and negative polarity pulses on the MHCD and plasma jet were compared, and the time-resolved optical emission spectra of excited species (N-2(+) and O) were studied. The results confirm that the electric field is a key factor for the propagation of the jet during the rising edge of the positive current pulse, while the gas expansion is mainly important for the jet propagation during the current stable phase. The time-resolved spectra show that the generation of specie O in the jet-driven by the electric field is more efficient.

Summary: In this study, the discharge characteristics and heating mechanisms of argon helicon plasma in different wave coupled modes with and without blue core were investigated. The results showed the existence of at least two distinct wave coupled modes, with one having a significant blue core and the other without. The emission intensity and electron density were measured, and it was found that the ion line intensity was dependent on both electron density and temperature, while the atom line intensity tended to be saturated in wave coupled modes due to neutral depletion. Theoretical analysis revealed that helicon waves were the dominant mechanism of power deposition or central heating of electrons in both modes.

Summary: In this study, the researchers revealed for the first time that the acetylation level of ATG4B at lysine residue 39 (K39) plays a crucial role in regulating its activity and autophagy. The deacetylation of ATG4B K39 by SIRT2 enhances ATG4B activity and autophagic flux, which can be countered by EP300/p300. Starvation treatment promotes the deacetylation of ATG4B K39 by suppressing EP300 and activating SIRT2, leading to the initiation of autophagy. The findings suggest that acetylation-mediated regulation of ATG4B activity is involved in the response to nutritional deficiency.

Summary: A one-step method of preparation using a novel nitrogen (N)-doped Fe-rich biochar (N5-CB) with high adsorption capacity for phosphate (P) removal from pickling wastewater was developed. The adsorption of P onto N5-CB was found to be mainly mediated by multilayer coverage, endothermic, spontaneous, and physical mechanisms. The Fe-P precipitation, Fe-O-P bonding, and electronic effect were identified as the main adsorption mechanisms. The highly active Fe-Nx sites and graphitic N induced by N doping played a crucial role in enhancing P adsorption.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
