Point-Mass Model for Nano-Patterning Using Dip-Pen Nanolithography (DPN)

Kang S-W, Banerjee D., Texas A&M University, US

Micro-cantilevers are frequently used as probes for micro-electromechanical systems (MEMS) based sensing applications. Usually micro-cantilever based sensors work by detecting changes in cantilever vibration modes (e.g., bending or torsional vibration frequency) or surface stresses - [...]

Using Scanning Thermal Microscopy Techniques for In-Situ synthesis of Carbon Nanotubes at “room temperature conditions”

Mukkisa S., Banerjee D., Texas A&M University, US

Carbon Nanotubes (CNT) were synthesized at room temperature conditions on a heated scanning probe without the use of conventional Chemical Vapor Deposition (CVD) apparatus or the process gases. The heated scanning probe is composed of [...]

Nanolithographic Patterning of Catalysts for Synthesis of Carbon Nanotubes

Gargate R.V., Banerjee D., Texas A&M University, US

Carbon nanotubes (CNT) were synthesized on specially custom designed MEMS chips under ambient conditions without requiring conventional Chemical vapor deposition(CVD) apparatus or process gases. In this approach, a layer of fullerene (C60) of 200 nm [...]

Investigation of Volume of Fluids (VOF) Method and System Models for Design of Microfluidic Ink Delivery Apparatus for Dip Pen Nanolithography (DPN)

Banerjee D., Texas A&M University, US

DPN™ is a versatile technology that leverages Scanning Probe Microscopy for applications in biotechnology, photomask repair, molecular-electronics, nano-electronics and mask-less lithography(1). In earlier studies (2) the DPN process was augmented for biotechnology applications (genomics, proteomics) [...]

System Model for a Novel No Moving Parts Diffuser Valve Based Diaphragm Actuated Micro Pump

Banerjee D., Yano K., Bart S.F., Coventor, US

Analytical results for oscillating flow in a channel indicate regions of high shear stress close to the wall along with the flow reversal in the central portion of the flow at certain frequencies of actuation. [...]
