An innovative fiber-based fracturing fluid technology has been developed to enhance the productivity of low-permeability and ultra-low-permeability reservoirs. However, few studies have focused on the influence of fiber on the rheological properties, microstructure and suspension behavior of a supramolecular fracturing fluid. In this article, the rheological properties, microstructure and proppant...
A fabrication process has been developed to create suspended carbon microelectromechanical system (C-MEMS) structures. SU-8, a negative photoresist, was used as the starting material and was converted to the desired carbon microstructures using pyrolysis in an inert atmosphere. Suspended carbon-micro and nano electromechanical system (C-MEMS/NEMS) structures with feature sizes down to 500nm were fabricated...
The addition of nanofeatures to carbon microelectromechanical system (C-MEMS) structures would greatly increase surface area and enhance their performance in miniature batteries, super-capacitors, electrochemical and biological sensors. Negative photoresist posts were patterned on a Au/Ti contact layer by photolithography. After pyrolyzing the photoresist patterns to carbon patterns, graphitic nanofibers...
