Chemiresistive Carbon Nanotube Sensors for N-Nitrosodialkylamines
(American Chemical Society (ACS), 2019-10)N-Nitrosamines are environmental genotoxicants that are widely encountered in air, water, and food. Contamination of indoor and outdoor air with N-nitrosamines has been reported on many occasions. Conventional detection ... -
A chemiresistive methane sensor
(Proceedings of the National Academy of Sciences, 2021)© 2021 National Academy of Sciences. All rights reserved. A chemiresistive sensor is described for the detection of methane (CH4), a potent greenhouse gas that also poses an explosion hazard in air. The chemiresistor allows ... -

Chemiresistive Sensing of Ambient CO2 by an Autogenously Hydrated Cu3(hexaiminobenzene)2 Framework
(American Chemical Society (ACS), 2019-06)A growing demand for indoor atmosphere monitoring relies critically on the ability to reliably and quantitatively detect carbon dioxide. Widespread adoption of CO2 sensors requires vastly improved materials and approaches ... -
Chemiresistive Sensor Array and Machine Learning Classification of Food
(American Chemical Society (ACS), 2019-07)Successful identification of complex odors by sensor arrays remains a challenging problem. Herein, we report robust, category-specific multiclass-time series classification using an array of 20 carbon nanotube-based chemical ... -
Chemiresistive Sensor Arrays from Conductive 2D Metal–Organic Frameworks
(American Chemical Society (ACS), 2015-11)Applications of porous metal–organic frameworks (MOFs) in electronic devices are rare, owing in large part to a lack of MOFs that display electrical conductivity. Here, we describe the use of conductive two-dimensional ... -
Chemiresistor Devices for Chemical Warfare Agent Detection Based on Polymer Wrapped Single-Walled Carbon Nanotubes
(MDPI AG, 2017-04)Chemical warfare agents (CWA) continue to present a threat to civilian populations and military personnel in operational areas all over the world. Reliable measurements of CWAs are critical to contamination detection, ... -
Chemiresistors for the Real‐Time Wireless Detection of Anions
(Wiley, 2019-11)Reported is an electrical transduction platform for real-time wireless anion sensing using single-walled carbon nanotubes (SWCNTs) noncovalently functionalized with squaramide-based anion binding selectors. Systematically ... -
Chemistry and material science at the cell surface
(Elsevier, 2010-03)Cell surfaces are fertile ground for chemists and material scientists to manipulate or augment cell functions and phenotypes. This not only helps to answer basic biology questions but also has diagnostic and therapeutic ... -

Chemistry of Nitrosyliron Complexes Supported by a beta-Diketiminate Ligand
(American Chemical Society, 2011-01)Several nitrosyl complexes of Fe and Co have been prepared using the sterically hindered Ar-nacnac ligand (Ar-nacnac = anion of [(2,6-diisopropylphenyl)NC(Me)]2CH). The dinitrosyliron complexes [Fe(NO)2(Ar-nacnac)] (1) and ... -
Chemistry of Personalized Solar Energy
(American Chemical Society (ACS), 2009-09)Personalized energy (PE) is a transformative idea that provides a new modality for the planet’s energy future. By providing solar energy to the individual, an energy supply becomes secure and available to people of both ... -
Chemistry of Simple Organic Peroxy Radicals under Atmospheric through Combustion Conditions: Role of Temperature, Pressure, and NO x Level
(American Chemical Society (ACS), 2021)Organic peroxy radicals (RO2) are key intermediates in the oxidation of organic compounds in both combustion systems and the atmosphere. While many studies have focused on reactions of RO2 in specific applications, spanning ... -
CHEMISTRY OF THE MOST METAL-POOR STARS IN THE BULGE AND THE z ≳ 10 UNIVERSE
(IOP Publishing, 2015-08)Metal-poor stars in the Milky Way are local relics of the epoch of the first stars and the first galaxies. However, a low metallicity does not prove that a star formed in this ancient era, as metal-poor stars form over a ... -
Chemistry with an Artificial Primer of Polyhydroxybutyrate Synthase Suggests a Mechanism for Chain Termination
(American Chemical Society (ACS), 2015-03)Polyhydroxybutyrate (PHB) synthases (PhaCs) catalyze the conversion of 3-(R)-hydroxybutyryl CoA (HBCoA) to PHB, which is deposited as granules in the cytoplasm of microorganisms. The class I PhaC from Caulobacter crescentus ... -
