As an example of the reactivity of nickel-catalyzed barium sulfate powder, almost complete conversion was attained in about 3 min at 850∘C under a hydrogen partial pressure of 86.7 kPa.
Analogous almost total mineralization was attained using the undivided cell with 0.05 mol dm−3 NatSO4 at current densities ≥ 100 mA cm−2, but with lower degradation rate and efficiency.
Almost overall mineralization is attained for the PEF treatments, more rapidly with the combined system due to the generation of higher amounts of hydroxyl radical from Fenton's reaction by the continuous Fe2+ regeneration at the CF cathode, accelerating the oxidation of organics to Fe(III)–carboxylate complexes that are more quickly photolyzed by UVA light.
Another observation was that in spite of incomplete filling complete or almost complete healing was attained, which indicates that the material or the procedure triggers a bone healing process beyond that facilitated by the material itself [ 19].
These four cases were developed on-site, by gradually increasing the liquid to gas flow rate until an almost complete CO2 capture was attained.
In Fig. 11a, the higher-order hybridized modes and Fano resonances for both the nanostructures are attained almost at the same spectral location as that in the far-field spectra.
Almost 100% 4CP removal was attained for ACS-800 in 60 min with an apparent rate constant of 0.083 min−1, which was much higher than that of S-free activated carbon (0.032 min−1).
