Security Auditing of Internet of Things Devices in a Smart Home

October 15, 2021
Author(s)
Suryadipta Mazumdar, Daniel Bostos, Anoop Singhal
Attacks on the Internet of Things are increasing. Unfortunately, transparency and accountability that are paramount to securing Internet of Things devices are either missing or implemented in a questionable manner. Security auditing is a promising solution

Collector Series-Resistor to Stabilize a Broadband 400 GHz Common-Base Amplifier

Author(s)
A. Gilad Kusne, Ichiro Takeuchi, Valentin Stanev, Johnpierre Paglione
Artificial intelligence and machine learning are becoming indispensable tools in many areas of physics, including astrophysics, particle physics, and climate science. In the arena of quantum materials, the rise of new experimental and computational

Cryogenic Characterization of a Superconductor Quantum-Based Microwave Reference Source for Communications and Quantum Information

October 13, 2021
Author(s)
Alirio De Jesus Soares Boaventura, Justus Brevik, Dylan Williams, Nathan Flowers-Jacobs, Manuel Castellanos Beltran, Anna Fox, Pete Hopkins, Paul Dresselhaus, Samuel P. Benz
We are developing a new instrument, the RF Josephson arbitrary waveform synthesizer (RF-JAWS), for communications metrology and quantum information applications. An important aspect of the RF-JAWS design is the accurate and traceable characterization of

Low-GWP Alternative Refrigerant Blends for HFC-134a: Interim Report

This project addresses the objectives of the Statement of Need number WPSON-17-20 "No/Low Global Warming Potential Alternatives to Ozone Depleting Refrigerants." Its goal is to identify and demonstrate performance of low global-warming-potential (GWP), non

STEP File Analyzer and Viewer User Guide (Update 7)

October 13, 2021
Author(s)
Robert R. Lipman
The STEP File Analyzer and Viewer opens a STEP (ISO 10303 - STandard for Exchange of Product model data) Part 21 file and (1) generates a spreadsheet or CSV files of all entity and attribute information, (2) creates a visualization (view) of part geometry

Thermal Analysis of Nanoparticles: Methods, Kinetics, and Recent Advances

October 13, 2021
Author(s)
Elisabeth Mansfield, Mark Banash
This chapter provides an overview of the thermal techniques available to study nanoparticles, with particular attention to thermogravimetric analysis, calorimetry and differential scanning calorimetry. The advantages of thermal analysis for nanoparticle

A Combinatorial Approach to TCO Synthesis and Characterization

October 12, 2021
Author(s)
J D. Perkins, Dennis W. Readey, J. L. Alleman, J A. del Cueto, King C. Li, T J. Coutts, R Stauber, C. H. Duncan, David P. Young, P A. Parilla, B Keyes, L M. Geduilas, Davor Balzar, Q Wang, D Ginley
We have developed the deposition, characterization and analysis tools necessary for a combinatorial approach to thin flim metal oxides, with a special focus on transparent conducting oxides (TCOs). We are presently depositing compositionally graded

A Comparative AFM Study of the Compressibility and Friction of Unmodified and Oligo(ethylene oxide)-Modified Alkane Thiol SAMs on Au(111) Using Nanografting

October 12, 2021
Author(s)
Ying Hu, David J. Vanderah, Guangyao Liu, William J. Price, Milan Mrksich, G Scoles
Self-assembled monolayers (SAMs) terminated with oligo(ethylene glycol) (OEG) segments are known to resist non-specific protein adsorption and are used in biomaterial and biosensor applications. In this report we use an atomic force microscopy (AFM)
