Summary: “The four-body distorted-wave approximation (DW-4B) is employed to study the electron removal from water molecules by hydrogen-like projectiles. The study reveals the relative importance of the intermediate ionization continua and electron-electron correlations in the removal process. Numerical calculations show good agreement with experimental findings.”

Summary: This paper investigates the scaling flows of quantum states in out-of-equilibrium many-body systems and provides analytical scaling solutions for the time evolved wave function. The study reveals universal scaling properties of interacting many-body systems and emphasizes the importance of correlations established in the short time period after sudden quench.

Summary: CO2 capture by amines has been extensively studied due to its industrial importance and the need to reduce CO2 emissions. Experimental evidence shows that CO2 sorption is accompanied by co-absorption of H2O. However, there is still no well-established analytical model to explain the enhancement of CO2 uptake capacity by water. In this paper, the authors generalize a model for CO2 sorption into various types of amines, including primary, secondary, tertiary, and quaternary ammonium, in both solution and solid forms. The model has been validated using experimental data for aqueous ammonia, and it offers a unified approach for treating isotherms of different amine systems.

Summary: This study focuses on the photoionization-excitation spectrum and multiple Auger decay process of Ne I. The spectrum analysis investigates complex satellite states Ne+ 1s???12p???1(1,3P)np (n = 3, 4, 5, 6, 7). The Auger decay process is studied using the multistep method, including cascade, knock-out, and shake-off mechanisms, for the satellite states Ne+ 1s???12p???1(1,3P)np (n = 3, 4) with two holes. The calculated ion yields of Ne2+, Ne3+, and Ne4+ are consistent with experimental values.

Summary: This study investigates the effects of alkaline metal promoters on the adsorption properties of MgO for CO2, and finds that alkaline metals can counteract the negative effects of SO2/O2/H2O and enhance the average adsorption energy of CO2. The research results have important practical applications.

Summary: We have calculated the cross sections for various processes in He+ + H collision and compared them with experimental and theoretical data. The excitation cross sections to H(n = 2) states agree well with the measurements of Geddes et al. The Balmer-alpha emission cross section of H is approximately half the size of the experimental data of Donnelly et al. The electron capture cross section is close to the experimental data of Lockwood et al and Olson et al. The ionization cross section is in accordance with the experimental data of Hsu et al.

Summary: Laboratory measurements of X-ray emissions from charge exchange between highly charged ions and neutrals reveal differences in state selectivity and emission between different target atoms and collision velocities. This suggests that accurate modeling of astrophysical charge exchange plasmas should consider target and velocity dependence.

Summary: This paper presents two types of stationary striations in an argon helicon plasma source, and investigates their formation and features under different conditions. The results show that gas pressure affects the striation spacing, while magnetic field and RF power have less significant impact. These striations are suggested to be strongly related to the non-local effect of electron kinetics in the plasma channel with a weak electric field, and different pressures in downstream and antenna regions lead to different types of striations in the argon helicon plasma source.

Summary: By using charge reduction, native mass spectrometry, and gas-phase activation methods, we demonstrated an integrated approach for in-depth analysis of PROTAC-linked ternary complexes. This approach may help in screening for ternary complex formation and PROTAC-protein contacts, potentially reporting on PROTAC-induced protein-protein interactions known to be correlated with PROTAC selectivity and efficacy.

Summary: This research experimentally measured the charge exchange process between highly charged ions and atomic hydrogen, covering a collision energy range relevant to the hot components of astrophysical charge exchange plasmas. The results are important for modeling X-ray emission resulting from the interaction of hot plasma with ambient neutral gas.

Summary: The article discusses the importance of understanding the properties of mobile impurities in quantum magnets for strongly correlated materials and high-temperature superconductivity physics, particularly focusing on the motion of hole-like defects through an antiferromagnet. It presents a nonperturbative theoretical approach to describe the microscopic properties of magnetic polarons and reveals qualitative differences from previous prediction schemes in the spatial structure of polarons in the strongly interacting regime.

Summary: Organic electrode materials have great potential in electrochemical energy storage devices due to their adjustable structure, low cost, and eco-friendliness. However, they often suffer from low electronic conductivity and high solubility. In this study, electron-donating and electron-withdrawing groups were functionalized on a porphyrin molecule to decrease solubility and regulate redox potential. Two novel cathodes, CuDETMP and CuDETCP, were synthesized and showed promising electrochemical performance with high reversible capacity and cycling stability. The study also provides insights into the correlation between substituents and electrochemical performance, offering a novel strategy for the design of high-energy rechargeable organic lithium batteries.
