Latest Water Permeability Figure for PES Membranes

One of the things that I’ve been working on recently is trying to explain the extreme elasticity of the pnc-Si material which is connected to its nanocrystalline structure. There are two parts in this question. First, how are amorphous or crystalline phases involved during stretching? Second, does the crystalline phase change under application of mechanical…

As seen in prior NRG post, ozone treated samples recover over about 24 hours. However, recent experiments at Gaborski Lab show high variability when using the Corona wand to treat samples with ozone.  The goal of this experiment was to determine the contact angles of PDMS samples when exposed to ozone treatment. PDMS samples were…

These are a couple of figures that may appear in the supplementary materials for the permeability paper. The first tries to explain that most of our permeability is due to the largest pores.  The lines plotted are the cumulative number of pores at each size (blue) and the cumulative permeability (green). The lines show that…
