Article Synopsis
- Researchers developed a new type of amphiphobic fluorinated surface-active ionic liquid (FSAIL) that can dissolve in water based on temperature changes.
- The FSAILs, containing specific anions, showed reduced solubility in both water and organic solvents compared to similar compounds without fluorine.
- These FSAILs effectively catalyzed the epoxidation of olefins using hydrogen peroxide, demonstrating high efficiency and the ability to be reused through phase separation and distillation after ten cycles.
Aside from the desulfurisation, the denitrogenation of fuels is of great importance to minimze the environmental impact of transport emissions. The oxidative reaction pathway of organic nitrogen in the catalytic oxidative denitrogenation could be successfully elucidated. This is the first time such a pathway could be traced in detail in non-microbial systems.

We estimate the sensitivity of the network to transient gravitational-wave signals for the third (O3), fourth (O4) and fifth observing (O5) runs, including the planned upgrades of the Advanced LIGO and Advanced Virgo detectors. We study the capability of the network to determine the sky location of the source for gravitational-wave signals from the inspiral of binary systems of compact objects, that is binary neutron star, neutron star-black hole, and binary black hole systems.

- On May 21, 2019, Advanced LIGO and Virgo detected a significant gravitational-wave signal known as GW190521, indicating a high probability event with a low chance of false alarms.
- The signal suggests it resulted from the merger of two black holes, one around 85 solar masses and the other about 66 solar masses, with the primary black hole likely being an intermediate mass black hole.
- The source of the merger is estimated to be about 5.3 billion light-years away, and the rate of similar black hole mergers is estimated to be about 0.13 mergers per billion cubic parsecs per year.
The critical micelle concentrations (CMCs) of several imidazolium-based ionic liquids (ILs) in aqueous HO (50 wt % in HO) were determined by tensiometry, conductometry, and the rate of catalytic epoxidation of -cyclooctene. CMC values in aqueous HO were significantly lower compared to values in pure water. In both HO solution and water, the CMC of all ILs decreases with an increasing alkyl chain length and increases with a rising temperature.
