Highly sensitive Scanning Capacitance Microscope
Summary—Emerging nanotechnology and biotechnology are in direct need of metrology tools with better than 10 –nm spatial resolution that are capable of imaging surfaces and nanoembeded structures. Scanning local probe microscopy (SLPM) techniques have advanced [...]
An All-Digital Cantilever Controller for MRFM and Scanned Probe Microscopy using a Combined DSP/FPGA Design
de Roover D., Porter II L.M., Emami-Naeini A., Marohn J.A., Kuehn S., Garner S., Smith D.D., SC Solutions, Inc., US
An all-digital cantilever controller for magnetic resonance force microscopy (MRFM) was developed through a close collaboration between SC Solutions, Cornell University, and the U.S. Army Research Laboratory. The advantage of an all-digital controller is its [...]
Analysis of Interfacial Water Structure close to Mixed Langmuir Monolayers by Sum-Frequency Spectroscopy
Sum frequency spectroscopy (SFS) in the OH stretching region was employed to obtain structural information about the interfacial water structure underneath Langmuir monolayers on H2O subphase. The films were composed by the model lipid dioctadecyldimethylammonium [...]
Effect of Surface Hydration and Interfusion of Suspended Silica Nanoparticles on Heat Transfer
Nanofluid suspensions enhance thermal conductivity and the heat transfer. The authors have previously shown that the Critical Heat Flux (CHF) of NiChrome wire in a silica nanofluid can be increased by 200% compared to conventional [...]
How to SPION Glass Transitions
The magnetic properties of superparamagnetic iron oxide nanoparticles (SPIONs) have made them useful tools in a variety of applications ranging from drug delivery to magnetorheologic valving in microfluidic systems. The structure of SPIONs is typically [...]
Analytical Methods for Nanotechnology
Growth in the fabrication of micro- and nano- engineered materials and systems has led to increased demand for analytical and characterization methods for these materials and systems. Many of the new manufacturing methods are extensions [...]
Integrated Multistage Supercritical Technology to Produce High Quality Vegetable Oil and Biofuels
A multi-step integrated technology to produce high quality vegetable oils and biodiesel fuels is proposed, documented for technical and economic feasibility, and preliminarily designed. The first step of the integrated system consists of soybean oil [...]
3D structure of nano-scale materials by total x-ray scattering
Knowledge about the three-dimensional (3D) structure, including the type and positions of atomic/molecular units in space, is an important prerequisite to understanding, predicting and improving properties of materials. With common materials it is routinely obtained [...]
A Circuit Compatible Analytical Device Model for Nanowire FET Considering Ballistic and Drift-Diffusion Transport
In this paper, we present a simplified circuit compatible analytical device model of nanowire FET for both ballistic and drift-diffusion transport, which can be efficiently used in any conventional circuit simulator like SPICE. The developed [...]
