Membrane-Based Environmental Cells for SEM in Liquids

December 1, 2016
Author(s)
Andrei A. Kolmakov
Environmental electron microscopy and Scanning Electron Microscopy (SEM) in liquids are among the most active research areas in modern electron microscopy and spectroscopy. Research interest in these techniques is broad as they are enabling the nanoscale

New Methods for Series-Resistor Calibrations on Lossy Substrates up to 110 GHz

December 1, 2016
Author(s)
Liu Song, Nate Orloff, Song Liu, Charles A. Little, Xifeng Lu, James Booth, IIja Ocket, Arkadiusz Lewandowski, Dominique Schreurs, Bart Nauwelaers
We present two new methods to perform seriesresistor calibrations on lossy substrates. Lossless calibration substrates, which are required by the traditional calibration comparison technique, are not needed. The proposed methods rely on the multiline TRL

Scalable Manufacturing of Layer-by-Layer Membranes for Water Purification

December 1, 2016
Author(s)
Christopher M. Stafford
Water is critical to the health and security of our nation. And as our population expands and water scarcity becomes a reality, we as a people need to think creatively on how we safeguard access to clean water. The manufacturing of today’s state-of-the-art

Structural Analysis of Dendrimers Based on Polyhedral Oligomeric Silsesquioxane and their Assemblies in Solution by Small-Angle Neutron Scattering: Fits to a Modified Two Correlation Lengths Model

December 1, 2016
Author(s)
Guangcui Yuan, Xing Wang, Decheng Wu, Boualem Hammouda
The small-angle neutron scattering (SANS) technique has been used to investigate the structure of dendrimers based on polyhedral oligomeric silsequioxane (POSS). Three generations and two distinct terminal groups (either vinyl or polyethylene glycol (PEG)

Trends in Thermoresponsive Behavior of Lipophilic Polymers

December 1, 2016
Author(s)
Priyanka Bhattacharya, Uma Shantini Ramasamy, Susan T. Krueger, Joshua W. Robinson, Barbara J. Tarasevich, Ashlie Martini, Lelia Cosimbescu
In an effort to look for correlations between viscosity index trends of polymers in oils and size changes of polymers in solution with temperature, the determination of the size of thermo-responsive polymers of various architectures (linear, comb, star

Analytical Gaps and Challenges for Particles in the Submicrometer Size Domain

November 30, 2016
Author(s)
Scott Aldrich, Shawn Cao, Andrea Hawe, Desmond Hunt, Linda Narhi, Dean C. Ripple, Satish Singh
This Stimuli article provides a technical discussion of the available technologies for submicrometer particle analysis, including consideration of the advantages, disadvantages, and technical gaps for each application. These methods can be used in the

Chip-Packaged Silicon Photonic Nanoscale Thermometers

November 30, 2016
Author(s)
Nikolai Klimov, Thomas P. Purdy, Zeeshan Ahmed
We report on the development of on-chip integrated packaged nanoscale silicon photonic themperature sensors capable to detect temperature difference as small as 70 µK, thus showing the potential to replace legacy-based resistance thermometers

Epoxy Composites Using Wood Pulp Components as Fillers

November 30, 2016
Author(s)
Douglas M. Fox, Noy Kaufman, Jeremiah W. Woodcock, Jeffrey W. Gilman, John R. Shields, Rick D. Davis, Szabolcs Matko, Mauro Zammarano, Chelsea S. Davis
The components of wood, especially lignin and cellulose, have great potential for improving the properties of polymer composites. In this chapter, we discuss some of the latest developments from our lab on incorporating wood based materials into epoxy
