Liu et al. have described a tri-block polymer system functionalized with galactose (PMAGP-POEGMA-Plys-Bodipy) [114]. Poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMA) plays the role of

The resulting catalyst exhibits a comparable triolein conversion (≈73%) after 4 h of reaction to CaO (≈76%), which is reportedly known to be highly active in the transesterification of triglycerides. In addition, while CaO showed a

• bonds dissociate and p(SRA-B) breaks down. The boronic ester bonds are dynamic and reversible [44]. They undergo transesterification with different alcohols but preferably interact with 1,2-cis- and 1,3-diols to produce stable five- and six-membered rings. Such diols include glucose, which displaces

This would result in a separation of the polystyrene chain (R1 in Scheme 1 and Scheme 2) from the short end group (R2 in Scheme 1 and Scheme 2

The dye is connected to the sulfur by a thioester link which is stable in aprotic solvents but undergoes slow hydrolysis in water or transesterification in ethanol. Nevertheless the NP labelled with two colours show the reasonably separated fluorescence

• Glycerol as a nontoxic fuel for fuel cells was proposed in 1964 [107]. Glycerol is the major product in biodiesel production by transesterification of plant oils and animal fats. Although it is used as a raw material in the chemical industry and animal feed, its market is saturated thus limiting the
