This study explores the novel approach of interface-crystallization-induced compatibilization (ICIC) via stereocomplexation as a promising method to improve the interfacial strength in thermodynamically immiscible polymers. Herein, two distinct reactive interfacial compatibilizers, poly(styrene--glycidyl methacrylate)--poly(l-lactic acid) (SAL) and poly(styrene--glycidyl methacrylate)--poly(d-lactic acid) (SAD) are synthesized via reactive melt blending in an integrated grafting and blending process. This approach is demonstrated to enhance the interfacial strength of immiscible polyvinylidene fluoride/poly l-lactic acid (PVDF/PLLA) 50/50 blends via ICIC.

- Self-medication (SM) is the act of taking medicine without a prescription and has increased during the COVID-19 pandemic, raising safety concerns.
- A study conducted in Southern Brazil found that 14.9% of undergraduate students practiced SM, with certain risk factors like income and type of university influencing this behavior.
- The most commonly used drugs included ivermectin and vitamins, and the findings aim to inform health education efforts to reduce SM and its associated risks.
Progressive recombination loss is a common feature of sex chromosomes. Yet, the evolutionary drivers of this phenomenon remain a mystery. For decades, differences in trait optima between sexes (sexual antagonism) have been the favoured hypothesis, but convincing evidence is lacking.
