A direct-write thick-film lithography process for multi-parameter control of tooling in continuous roll-to-roll microcontact printing
Roll-to-roll (R2R) microcontact printing ([mu]CP) aims to transform micron-precision soft lithography in a continuous, large-scale, high-throughput process for large-area surface patterning, flexible electronics and engineered meta-surfaces. Efforts to implement this hybrid process have been …

Fabrication and qualification of arbitrarily patterned seamless tooling for continuous roll-to-roll microcontact printing
Microcontact printing is form of soft lithography utilizing an elastomeric stamp with a molded relief pattern to print features on substrates through ink transfer at micron and nanometer scales. This is a low-cost technique when compared with other printing and patterning processes. Traditional …

Wettability of graphitic materials and their application in separation
… wettability of graphene. Therefore, nanoscopic, microscopic and spectroscopic investigations under controlled conditions were performed to elucidate the relationships between surface defects, functionality, doping and wettability of graphene. First study on wettability focuses on the influence of …

Fully Aerosol-Jet Printed Trilayer Electrochemical Actuator
… the theoretical possibility of miniaturisation, microfabrication and micro-patterning of trilayer ECAs have remained difficult due to the need to pattern and align electrodes on both sides of the polymer electrolyte while avoiding short circuits between adjacent and opposing electrodes. Existing …

Cancer metastasis and elasticity of microenvironment
… mechanisms and parameters within the cellular microenvironment that initiate the onset of metastasis remain largely unknown (Chapter 1). Such a gap in the understanding and prediction of the onset of metastasis is of particular concern in colon cancer. We discovered that HCT-8 colon cancer …
