A method to determine Poisson's ratio of thin films employing a simple experimental deflection test and a simulation program has been developed. According to the method, knowing Young's modulus and measuring the deflection at an arbitrary point on th

We have developed two methods to characterize and reduce the deformation of polydimethylsiloxane (PDMS) during its planar molding process. The first method was to determine the local residual strain of PDMS using ink dots. The information of the loca

A variable height flow cell was used to measure the adhesion properties of the neural cell line of neuroblastoma X glioma (NG108-15) cells cultured on substrates of organosilane self-assembled monolayers (SAMs). The SAMs tested in this study were 13F

Finding our way out at a large university campus is a problem. We developed VTQuest, http://sunfish.cs.vt.edu/VTQuestV, as a web-based software system to solve this problem for the campus of Virginia Tech (http://www.vt.edu/). VTQuest enables (a) mul
