Summary: In order to study fertility mechanisms, experiments are conducted using solvents such as ethanol (EtOH) or dimethyl sulfoxide (DMSO) to incubate spermatozoa in the presence of dissolved molecules. However, the effect of the solvents on sperm parameters and the outcome of the experiments is often overlooked. This study investigated the impact of EtOH and DMSO on sperm motility, vitality, capacitation, and acrosome integrity, and found significant relationships between increasing solvent concentrations and these parameters.

Summary: Water-lean amine absorbents, using dimethyl sulfoxide (DMSO) as a cosolvent, were developed for efficient CO2 capture. The DMSO-based amine blends maintained a monophasic state before and after CO2 absorption, and showed high cyclic capacity and low energy consumption. Increasing water content in the absorbents improved absorption capacity but significantly increased regeneration energy.

Summary: We introduce the transient THz Stark effect to modify the electronic absorption spectra of dye molecules and determine molecular interactions and dynamics. The non-equilibrium response of Betaine-30 in a polar solution is probed via transient absorption changes induced by picosecond electric fields. The response is governed by the dipole energies in the THz field, allowing for quantification of electric forces in a structurally frozen molecular environment.

Summary: 5-Aminoquinoline is used as a fluorescent probe to study preferential solvation in binary solvent mixtures. The roles of solvent polarity and solute-solvent hydrogen bonding are delineated, showing distinct behaviors in protic and aprotic solvents. Solvation dynamics mark the formation of solvent shell around the probe, with different processes observed in methanol and acetonitrile. Translational diffusion is the rate-determining step for solvation shell formation, with time constants estimated from fluorescence transients and time-resolved emission spectra.

Summary: The diverse uses of gold and its crucial role in the global economy are growing, particularly during cycles of economic crises. The broad use of cyanide by conventional gold-mining companies and mercury by artisanal miners poses environmental and health concerns for local communities. This article introduces an innovative gold-leaching process using a non-toxic organic reagent, dimethyl sulfoxide (DMSO), a water-free lixiviant that extracts gold from ores/concentrates in combination with copper halides. The results of laboratory experiments using dimethyl sulfoxide and a sample of high-grade gold ore from Colombia show that 96.5% of the gold was extracted in 2 h at room temperature. The typical cyanidation process using 5 g/L of CN- at pH 10.5 on the same ore sample obtained 97% gold extraction in 24 h at ambient temperature. The gold extracted using DMSO was precipitated by adding a mild acidic solution, and the reagent can be recycled via distillation and reused in repeating cycles. The results show that DMSO can be used as a promising agent for gold leaching, offering a straightforward, cost-effective, and eco-friendly procedure with minimal chemical waste.

Summary: The development of lithium batteries, including lithium-ion batteries and lithium-air batteries, is a key technological breakthrough in renewable energy storage. However, designing lithium batteries with high specific power and stability remains challenging. This study systematically investigates the solvation structure and thermodynamic stability of three common inorganic Li salts (LiClO4, LiBF4, and LiPF6) and O2 in two aprotic solvents (DMSO and CH3CN) from an atomic viewpoint. The results provide insights into the solvation shells, diffusion coefficients, and stability performances of the Li+ components in the electrolytes, highlighting the importance of selecting suitable Li salts and solvents for optimized battery performance.

Summary: The study on time resolved fluorescence spectroscopic investigation of four Schiff base anions reveals that the excited state dynamics is influenced by solvent properties such as polarity, viscosity, and hydrogen bond donating ability. The fluorescence lifetimes of the anions are found to be longer in viscous protic solvents and surprisingly even longer in less viscous aprotic solvents, possibly due to hydrogen bond-assisted nonradiative phenomena.

Summary: This article investigates the reorganization energy of electron transfer in room-temperature ionic liquids (ILs) and finds that it is similar to that in cyclohexane. This result contradicts common knowledge, as ILs and cyclohexane have different polarities. The study also utilizes molecular dynamics simulations to support the conclusion of low reorganization energy.

Summary: The charge redistribution upon optical excitation of various necked homodimer colloidal quantum dot molecules (CQDMs) is investigated using single-particle emission spectroscopy. By tuning the hybridization of the electron wavefunctions at a fixed center-to-center distance through controlling the neck girth, we reveal two coupling limits: weak-coupling regime and strong-coupling regime. The emitted photons from CQDMs in the weak-coupling regime show high bunching while the antibunching is regained at the strong-coupling regime.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
