Gelation temperature of MC was reduced from 59°C to 54°C with the addition of 10% PEG. Sodium tartrate (NaT) and sodium citrate (NaC) were added to the MC-PEG solution to further reduce the gelation temperature close to physiological temperature. Different

Tartaric acid (TA), a dicarboxylic acid, can act as a compatibiliser in starch/polyester blends. A mixture design was proposed to evaluate the effect of TA on the properties of starch/poly (butylene adipate co-terephthalate) (PBAT) blown films plasticised with glycerol. The

The formation of diastereomeric cocrystals of malic acid and tartaric acid was investigated by liquid-assisted grinding in the solid state. We demonstrate that racemic malic acid can be converted into two distinct diastereomeric cocrystal phases by grinding with a single
