Low-cost, concentrated sugar production from lignocellulosic feedstocks

Mohapatra S., Hemyeri R., Manesh A., American Science and Technology Corporation, US

In the last few years, sugar is emerged as the main feedstock to derive several potential biofuels and chemicals. Most of these chemicals can be used to replace petrochemical fuels. The cost availability of these [...]

An Online Mems Design Tool That Lays Out and Simulates a Parameterized Array from a Reference Device

Marepalli P., Clark J.V., Purdue University, US

We present an online MEMS design tool that lays out and simulates a parameterized array from a reference device. These automated features are implemented in our tool called SugarCube, which is readily available on nanoHUB.org. [...]

A Systems Design Framework Based in Matlab That Integrates Sugar, Spice, Simulink, Fea Comsol, and GDS-II Layout

Marepalli P., Clark J.V., Purdue University, US

We present a systems design framework called iSUGAR that integrates SUGAR, SPICE, SIMULINK, FEA COMSOL, and GDS-II layout. SUGAR is known for its ease and speed of complex MEMS configuration and parameterization; SPICE is known [...]

Simplifying the Designing of a MEMS-based Nanoscale Material Testing Device

Bansal R., Clark J.V., Purdue University, US

Microelectromechanical-systems (MEMS) are increasingly used for accurate mechanical characterization of nanostructures. However, the performance of such systems highly depends on their structural design. Optimizing the performance of the device using distributed analysis is computationally expensive, [...]

Lumped Modeling of Carbon Nanotubes for M/NEMS Simulation

Bansal R., Clark J.V., Purdue University, US

The construction and analysis of the CNT structure is extremely difficult and requires expertise in nanostructure physics. This limits access to molecular dynamics specialists and does not allow the exploration of CNTs as components of [...]

New Numerical Techniques and Tools in SUGAR for 3D MEMS Simulation

Bai Z., Bindel D., Clark J., Demmel J., Pister K., Zhou N., University of California Davis, US

SUGAR is a modified nodal analysis package for 3D MEMS simulations that owes its heritage and its name to the SPICE family of circuit simulation. SUGAR has undergone the stage of proof-of-concept which showed that [...]

Modified Nodal Analysis for MEMS with Multi-Energy Domains

Clark J.V., Zhou N., Pister K.S.J., University of California at Berkeley, US

A modified nodal analysis approach for the design, simulation, and display of three-dimensional microelectro-mechanical systems with coupled energy domains is presented. Static, steady-state, and transient algorithms are introduced followed by examples. Transient and static analysis [...]

Nodal Analysis for MEMS Design Using SUGAR v0.5

Zhou N., Clark J.V., Pister K.S.J., UC-Berkeley, US

This paper presents the development of a simulation program (SUGAR) for planar MEMS devices. The approach is based on nodal analysis to solve coupled nonlinear differential equations. The current version SUGAR vO.5 can perform DC, [...]
