Integrated Business and Engineering Educational Experience for Medical Students in the Development of Pediatric Medical Devices.

Background: There are few opportunities in undergraduate medical education that provide formal training in engineering and scientific innovation. Institutions have sought to address student-specific career goals through combined degree programs such as the Medical Scientist Training Program and MD/MBA. However, only a small percentage of medical students pursue these additional degrees.

Antibiofilm Effects of Modifying Polyvinylidene Fluoride Membranes with Polyethylenimine, Poly(acrylic acid) and Graphene Oxide.

Biofouling in membrane filtration systems poses significant operational challenges, leading to decreased permeate flux. The aim of this work was to study the anti-biofilm properties of new nanofiltration membranes produced via layer-by-layer, LBL, assembly by coating a polyvinylidene fluoride (PVDF) support with a polyethylenimine (PEI) and poly(acrylic acid)/graphene oxide (PAA-GO) mixture. The membranes were characterized according to contact angle, scanning electron microscopy (SEM), atomic force microscopy and their Z-potential.
