Understanding the Mechanical and Viscoelastic Properties of Graphene Reinforced Polycarbonate Nanocomposites Using Coarse-Grained Molecular Dynamics Simulations.

Incorporating graphene nanosheets into a polymer matrix is a promising way to utilize the remarkable electronic, thermal, and mechanical properties of graphene. However, the underlying mechanisms near the graphene-polymer interface remain poorly understood. In this study, we employ coarse-grained molecular dynamics (MD) simulations to investigate the nanoscale mechanisms present in graphene-reinforced polycarbonate (GRPC) and the effect of those mechanisms on GRPC's mechanical properties.

Secondary Kwashiorkor Disease in a Patient with Gastric Bypass Surgery and Short Gut Syndrome.

BACKGROUND Kwashiorkor disease is a subtype of severe acute protein malnutrition characterized by peripheral edema associated with hypoalbuminemia and ascites. It can result from both protein deficiency and protein loss. In resource-poor countries, the disease often is caused by inadequate dietary intake, but in resource-rich countries, it can be seen as a rare complication of severe malabsorption.

Flow-Regulated Growth of Titanium Dioxide (TiO ) Nanotubes in Microfluidics.

Electrochemical anodization of titanium (Ti) in a static, bulk condition is used widely to fabricate self-organized TiO nanotube arrays. Such bulk approaches, however, require extended anodization times to obtain long TiO nanotubes and produce only vertically aligned nanotubes. To date, it remains challenging to develop effective strategies to grow long TiO nanotubes in a short period of time, and to control the nanotube orientation.

Classroom to Clinic: Merging Education and Research to Efficiently Prototype Medical Devices.

Innovation in patient care requires both clinical and technical skills, and this paper presents the methods and outcomes of a nine-year, clinical-academic collaboration to develop and evaluate new medical device technologies, while teaching mechanical engineering. Together, over the course of a single semester, seniors, graduate students, and clinicians conceive, design, build, and test proof-of-concept prototypes. Projects initiated in the course have generated intellectual property and peer-reviewed publications, stimulated further research, furthered student and clinician careers, and resulted in technology licenses and start-up ventures.
