ToF-SIMS demonstrated that the process not only avoids photoresist residues, but also significantly reduces PMMA contamination without introducing Al atomic residues. The morphology also shows that the graphene pattern prepared by this process is flatter and cleaner. More importantly, electrical tests show that Al sacrificial layer process can significantly improve the consistency of the resistance (standard deviation reduced by 41.9%) and the sensitivity of the device (temperature sensor sensitivity increased by 54.41%).

An electrospinning collector is thus designed to produce nanofibrous membranes with defined alignment and pore size. The cell study shows that randomly oriented nanofibers with small pores promote self-renewal and adipogenic and osteogenic differentiation of human mesenchymal stem cells.
