Filtration of molecules by nanometer-sized structures is ubiquitous in our everyday life, but our understanding of such molecular filtration processes is far less than desired. Until recently, one of the main reasons was the lack of experimental methods that can help provide detailed, microscopic pictures of molecule— nanostructure interactions. Several innovations in experimental methods, such as nuclear track-etched membranes developed in the 70s, and more recent development of nanofluidic molecular filters, played pivotal roles in advancing our understanding. With the ability to make truly molecular-scale filters and pores with well-defined sizes, shapes, and surface properties, now we are well positioned to engineer better functionality in molecular sieving, separation and other membrane applications. Reviewing past theoretical developments often scattered across different fields and connecting them to the most recent advances in the field would be essential to get a full, unified view on this important engineering question.

In fact, according to the Centers For Disease Control and Prevention CDC , estimates show that around 75 percent of all women will have a vaginal yeast infection at some point in their lives! What causes a vaginal yeast infection? You guessed it: yeast! But did you know that the same type of fungal yeast that grows outdoors on trees and plants is actually very similar to the type that can develop inside the body and lead to an infection?
Much like The Simpsons , South Park uses a very large ensemble cast of recurring characters. It became infamous for its profanity and dark , surreal humor that satirizes a wide range of topics towards a mature audience. Parker and Stone developed the show from The Spirit of Christmas , two consecutive animated shorts. The latter became one of the first Internet viral videos , ultimately leading to South Park 's production. Since its debut on August 13, , episodes of South Park have been broadcast.
