It has been reported that the epoxidation of a,p-unsaturated carbonyl compound can be conveniently accomplished by using sodium perborate (SPB) in aqueous media at pH 8 to give a,P-epoxyketones (Scheme 63). 

Nitriles can also be converted into amides by using sodium perborate (SPB NaB03, nH O, n = 1 to 4) in aqueous media such as H20-Me0H H20-acetone and H20-dioxan . An interesting application of this reaction is the synthesis of quinazolin-4-(3H)-ones (Scheme-88). 

Another cheaply available industrial chemical, sodium perborate (SPB) in aqueous methanolic sodium hydroxide oxidises sulphides into sulphones in very good yield.Sulphides can be oxidised to sulphoxides exclusively by using commercial 70% aqueous TBHP in water in the heterogeneous phase at 20-70 Using this procedure some of the sulphides like Et S, PhSMe, PhSPh, p-OHCjH SMe can be oxidised quantitatively into the corresponding sulfoxides at 20 °C. 

An optimum approach to further development of the MBRU-12 concept could be to join the efforts of Russian enterprises such as SPb AEP, OKBM and IPPE. Previously such cooperation produced detailed designs of power units based on the fast sodium cooled reactors BN-600 and BN-800. 

The most probable scenario for further development of the BMN-170 is to join efforts of the originators of the initial (conceptual) BMN-170 designs, namely, such Russian enterprises as SPb AEP, OKBM and IPPE. Previously, full-scale designs of power units using fast sodium reactors BN-600, BN-800 were developed through such cooperative efforts. 

Thanks to the versatility of the Raman spectroscopy, nanoparticles AgNP(25) were used also to detect other policyclic aromatic pollutants (PAHs), like benzo [cjphenanthrene, triphenylene, and coronene [67]. In this case, selectivity is not as important as in other sensors, because the pollutant molecule can be in principle identified by its Raman spectrum. The affinity constants and the limits of detection of PAHs were also determined. In 2012, Coleman and co-workers developed a method to determine the critical micellar concentration (CMC) of cationic surfactants exploiting the SPB of a series of sulfonato calix [njarene-capped AgNPs [68]. The nanoparticles were synthesized by reducing AgNOs with sodium borohydride in aqueous solution in the presence of the sulfonate calix[n]arene derivatives 24, 26 and 27 (see Fig. 35.15) and characterized by TEM, DLS and UV-visible spectroscopy.

Sodium perborate (SPB NaB03 H20, = 1 to 4) is a mild and inexpensive oxidant [28] that, in aqueous media at pH 8-10, gives a,p-epoxyketones in good yields [29] (Scheme 6.3). 

SPB is another cheap and large-scale industrial chemical that in aqueous methanolic sodium hydroxide smoothly oxidizes sulfides into sulfones with excellent yield [50].

The contrast is enhanced compared with the original particles (bottom) by replacing the sodium counterions of the polyelectrolyte chains by cesium ions (top left) and, additionally, by BSA molecules that are adsorbed in close correlation with the polyelectrolyte chains (top right).

Magnetic NPs exhibit stability when NaPSS has been grafted onto the surface to form a core—shell stmcture (Bakandritsos et al., 2008). Organic-inorganic hybrid SPB with grafted poly(sodium-p-styrenesulfonate) on modified Si02 particles have been reported (Fig. 4.16) (Su et al., 2012).
