The image below was taken with UR’s new S/TEM, the FEI Technai F20.  It has the capability of resolving lattice images which should benefit the materials development effort.  However, we will still rely on Karen’s TEM for most of our imaging since the throughput is higher on that tool.

Scope: Human umbilical vein endothelial cells (HUVEC) and adipose derived stem cells (ADSC) were co-cultured on SiO2 low density 3um pore membranes. The ADSCs were initially seeded onto the membranes, at 6 hours the membranes were flipped over and placed into a 24 well plate and HUVECs were seeded. Cells were grown for 3 days…

Overview: After trying an initial experiment of growing ADSCs on TCP and 3um translucent (TE) membranes and then placing them onto TCP or 3lp SiO2 membranes, it was determined that further studies should be conducted. For this experiment we grew ADSC on TCP, 3um translucent (TE) membranes, and 0.4um transparent (TE) membranes. Once the cells…

Membranes Promote Endothelial Differentiation of Adipose-Derived Stem Cells and Perivascular Interactions Submitted to Journal of Cellular and Molecular Bioengineering (a BMES journal)   ADSC-All-Figures FIGURE 1.  Ultrathin microporous silicon dioxide (SiO2) membranes. (A) 300 nm thick SiO2 membranes were fabricated on silicon wafers and etched into 5.4 x 5.4 mm dies with 2 x 2…

We deposited a 20/60/20 nm OSO stack for an ellipsometry test.  We decided to try annealing the un-patterned wafer in the RTP at 1050 C with no susceptor with a 100 C/s ramp for 60 s. The attached SEM images show pores forming.  With these encouraging results, we are considering depositing 40, 50 and 60…
