Summary: The Middle East Respiratory Syndrome-coronavirus (MERS-CoV) primarily spreads to humans through dromedary camels in Africa, the Middle East, and Central or South Asia, with limited human-to-human transmission. Only cases in humans from the Arabian Peninsula have been reported so far, and no zoonotic MERS cases have been found in Africa or Asia, despite the high density of infected camels. Further investigation into this disparity is crucial due to the pandemic potential of MERS-CoV.

Summary: Through molecular dynamics simulations, researchers have found that many different substrates can promote the formation of pristine I-c, I-c can be selectively nucleated even with mild supercooling, the water contact layer's resemblance to a face of ice is the key factor determining the polytype selectivity and nucleation temperature, and substrate lattice match to ice is not indicative of the polytype obtained.

Summary: This study calculates sea ice concentration (SIC) budgets for the Southern Ocean using five ocean-sea ice reanalyses and compares them with observations. The assimilation of SIC improves the representation of sea ice extent and area in the reanalysis products. However, the differences in the budgets of SIC changes are influenced by atmospheric and oceanic forcings, as well as model configurations. The results suggest that future reanalyses should focus on improving the modeling of sea ice velocities.

Summary: In the quest for post-CMOS technologies, researchers have shown promising results in experimenting with topologically protected ferromagnetic whirls such as skyrmions and their anti-particles, which can serve as solitonic information carriers. Antiferromagnetic analogues have become the subject of intense focus due to their predicted relativistic dynamics and potential for fast deflection-free motion and size scaling, although experimental demonstration in natural antiferromagnetic systems has yet to be achieved. By utilizing a first-order analogue of the Kibble-Zurek mechanism, a family of topological antiferromagnetic spin textures has been stabilized on an Earth-abundant oxide insulator, showing potential for low-energy antiferromagnetic spintronics at room temperature.

Summary: Mixed-halide perovskite films of MAPb(Br0.5I0.5)(3) and FA(0.83)Cs(0.17)Pb(Br0.4I0.6)(3) exhibit clear differences in compositional and optoelectronic changes associated with halide segregation. MAPb(Br0.5I0.5)(3) shows low-barrier ionic pathways that enhance stability against halide segregation, while FA(0.83)Cs(0.17)Pb(Br0.4I0.6)(3) lacks such pathways and undergoes considerable ionic rearrangement under prolonged illumination.

Summary: The intriguing magnetic behavior of two-dimensional chromium trihalide materials and the potential for spintronics and magnonics are studied. Different stacking in (CrBr3/CrI3) hetero-bilayers can result in different magnetic properties. Optical generation and electric detection of pure magnon spin currents as well as simultaneous realization of magnon spin currents and topological domain walls are proposed. The advantages of (CrBr3/CrI3) hetero-bilayers over (CrI3)(2) homo-bilayers in realizing magnon spin currents are highlighted.

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.
