A Fresh Perspective on the Internal Plasticizing Effect in Non-Polymeric Glass-Formers Open
The internal plasticizing effect occurs when a flexible substituent, especially one linked to a rigid moiety, lowers the glass transition temperature (Tg) of an organic compound by disrupting molecular packing and increasing the internal m…
Continuous Flow Synthesis of Nitrofuran Pharmaceuticals Using Acetyl Nitrate Open
Nitrofurfural is a key building block for the synthesis of antimicrobial nitrofurans as active pharmaceutical ingredients. Its synthesis involves the nitration of furfural, a substrate derived from biobased resources. However, furfural has…
