Here, we describe a laboratory-scale method for conducting AFEX pretreatment on lignocellulosic biomass.
Development of a 3D Graphene Electrode Dielectrophoretic Device Hongyu Xie1, Radheshyam Tewari2, Hiroyuki Fukushima3, Jeffri Narendra3, Caryn Heldt1, Julia King1, Adrienne R. Minerick1 1Department of Chemical Engineering, Michigan Technological University, 2Department of Mechanical Engineering, Michigan Technological University, 3XG Sciences, Inc. A microdevice with high throughput potential is used to demonstrate three-dimensional (3D) dielectrophoresis (DEP) with novel materials. Graphene nanoplatelet paper and double sided tape were alternately stacked; a 700 μm micro-well was drilled transverse to the layers. DEP behavior of polystyrene beads was demonstrated in the micro-well.
