A longitudinal study of math skills in heritage bilingual children: profiles of strengths and weaknesses.

Many children are exposed to a heritage language in the home context, and they learn mathematics in the school context in the societal language (Italian in the present study). More evidence is needed on how Heritage Bilinguals (HBs) perform in different subtypes of numeracy and mathematics skills in a longitudinal perspective. This longitudinal study aimed to analyze the mathematical skills of heritage bilingual children.

Enzymatic synthesis of biobased aliphatic-aromatic oligoesters using 5,5'-bis(hydroxymethyl)furoin as a building block.

5,5'-Dihydroxymethyl furoin (DHMF) is a novel biobased difuranic polyol scaffold, achievable from the benzoin condensation of 5-hydroxymethylfurfural (HMF), which has recently been employed as a monomer for the preparation of cross-linked polyesters and polyurethane. Its upgrading by means of enzymatic reactions has not yet been reported. Here we demonstrated that lipase B (CALB) is a suitable biocatalyst for the selective esterification of the primary hydroxyl groups of DHMF.
