“…E.g., for ISB residues sampled at three different locations in the boom after ISB of IFO180 [ 37 ], the BE was estimated to vary from approximately 30–60% (sample with highest BE was used in this study). Estimated BE for ULSFO was 57 % and more than 95 % for MGO [ 16 ].…”

“…The offshore in situ burning experiments took place at the former Frigg field in the Norwegian part of the North Sea in mid-June [ 16 ]. About 6 m 3 of each oil were released and contained into a fire-boom before being ignited by use of a "Pyro-drone" (DESMI) with a gelled ignitor consisting of diesel (80 %) and gasoline (20 %).…”

“…The GC chromatograms of the oils and their ISB residues are given in Supplementary Information (SI2), Figures S1 to S3. A more detailed characterization of the physical-chemical properties of the burned residues is reported in Faksness et al [ 16 ]. The ISB residues of MGO and IFO180 had very different physical properties, which was reflected in their viscosities.…”

“…As a part of the "Oil-on-water" experiments in the North Sea in 2018 (OOW2018) and 2019 (OOW2019), seven experimental ISB with different oil types were performed. In these field experiments testing of ignitors (hand-held or from drone), validation of fire booms, and estimation of burning efficiency were included [ 16 ]. Photo from one of the burns is shown in Figure S5 in the Supplementary Information (SI5).…”

“…These residue samples are used in the present study. A more extensive characterization of the physical-chemical properties of the burned residues and the smoke emissions are discussed in Faksness et al [ 16 ] and the potential for human exposure during ISB in Szwangruber et al [ 17 ]. The operational aspects of these ISBs are described and discussed in Jensen et al [ 18 ].…”

Highlights Chemistry and acute toxicity (early life stage of C. finmarchicus ) in LE-WAF of unburned and burned ULSFO, IFO180 and MGO . WAFs of ISB residues seem to be less acute toxic than WAFs of initial unburned oils. Predicted toxic units indicate that the PAHs seem to contribute most to the toxicity. The burns reduced the total mass of PAH by >90 % compared to the released, unburned oils. Potential impact of ISB depends on e.g. burn efficiency and residue properties.

The proton exchange membrane (PEM) is the core component of a high‐performance proton exchange membrane fuel cell (PEMFC). Since the traditional PEM has the disadvantages of poor cell performance and high cost, a new kind of PEM with good proton conductivity, low cost and simple preparation should be explored. In this paper, several different binary hybrid membranes were successfully prepared through one‐step encapsulation of different ionic liquids (ILs) in sulfonated poly(ether ether ketone) (SPEEK). The prepared membranes were characterized by scanning electron microscope (SEM), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FT‐IR), X‐ray photoelectron spectroscopy (XPS), proton conductivity measurements and dynamic mechanical analysis (DMA). SEM images showed that ILs were fully doped into SPEEK. FT‐IR and XPS proved that SPEEK and IL formed a new chemical bond combined with intermolecular hydrogen bonds. The TG results showed that the binary hybrid membranes could maintain stability even at 300°C. The water uptake and swelling ratio showed that the water absorption capacity of the binary composite membrane played a vital role in improving proton conductivity. The proton conductivity study showed that ILs doping also helped to improve the proton conductivity of the SPEEK membrane. When the doping amount of IL was maintained at 30 wt.%, it has the highest proton conductivity, 25 mS cm−1 at 120°C. It was proved that anhydrous hybrid membrane tetraphenyl imidazole sulfate/SPEEK ([IM2][H2PO4]/SPEEK) could be used in PEMFC at medium temperature.

The development of recyclable, durable and widely adaptable porous hydrophobic materials is of vital importance for the effective separation of leaking oil-water mixtures. Herein, we functionally modi ed melamine formaldehyde resin sponge (MFRS) with PMMA, PDMS-PMMA and PDMS-PGMA via a facile solution-immersion process. Compared with PMMA-coated MFRS, the improvement of the water contact angle (WCA) and oil-water mixture separation e ciency of PDMS-PMMA/MFRS were su cient enough to verify that the introduction of PDMS block enhanced the hydrophobic performances of the material.Moreover, the importance of the GMA block in PDMS-PGMA/MFRS was con rmed by the excellent performance of the material in oil-water separation recycling experiments, with 91.5% separation e ciency after 8 runs. The fabricated PDMS-PMMA/MFRS with improved WCA (155°) and oil-water mixture separation e ciency (99.1%), demonstrated superhydrophobic property, which is attributed to the introduction of hydrophobic block PDMS and coating-induced surface geometric folds. Besides, the acidresistance and widely adaptable (e cient separation of various oil-water mixtures) performances of PDMS-PGMA/MFRS were experimentally con rmed. The freely available manufacturing raw materials and facile functionalization process of PDMS-PMMA/MFRS offers possibilities for its adoption in the e cient cleanup of oil spills.
