Nano Silica and Metakaolin Effects on the Behavior of Concrete Containing Rubber Crumbs
(MDPI, 2020-11-08)The excessive production of worn tires remaining from the transportation system and the lack of proper procedures to recycle or reuse these materials have caused critical environmental issues. Due to the rubber’s ... -
NanoARG: a web service for detecting and contextualizing antimicrobial resistance genes from nanopore-derived metagenomes
(2019-06-07)Background Direct and indirect selection pressures imposed by antibiotics and co-selective agents and horizontal gene transfer are fundamental drivers of the evolution and spread of antibiotic resistance. ... -
Nanomaterial Disposal by Incineration
(The Royal Society of Chemistry, 2013-07-11)As nanotechnology-based products enter into widespread use, nanomaterials will end up in disposal waste streams that are ultimately discharged to the environment. One possible end-of-life scenario is incineration. This ... -
Nanomaterial enabled sensors for environmental contaminants
(2018-11-22)The need and desire to understand the environment, especially the quality of one’s local water and air, has continued to expand with the emergence of the digital age. The bottleneck in understanding the environment has ... -
Nanoparticulate Ni(OH)(2) Films Synthesized from Macrocyclic Nickel(II) Cyclam for Hydrogen Production in Microbial Electrolysis Cells
(Electrochemical Society, 2016-01-01) -
Natural Hazards Reconnaissance With the NHERI RAPID Facility
(2020-11-11)In 2016, the National Science Foundation (NSF) funded a multi-institution interdisciplinary team to develop and operate the Natural Hazards Reconnaissance Facility (known as the "RAPID") as part of the Natural Hazards ... -
Natural, incidental, and engineered nanomaterials and their impacts on the Earth system
(2019-03-29)Nanomaterials are critical components in the Earth system's past, present, and future characteristics and behavior. They have been present since Earth's origin in great abundance. Life, from the earliest cells to modern ... -
A new approach for measuring the carbon and oxygen content of atmospherically relevant compounds and mixtures
(2020-09-18)Due to its complexity, gas- and particle-phase organic carbon in the atmosphere is often classified by its bulk physicochemical properties. However, there is a dearth of robust, moderate-cost approaches to measure the bulk ... -
Nitrogen-doped activated carbon as a metal free catalyst for hydrogen production in microbial electrolysis cells
(The Royal Society of Chemistry, 2014-09-26)Nitrogen-doped activated carbon was investigated as an alternative cathode catalyst for hydrogen production in microbial electrolysis cells (MECs). Both electrochemical and MEC tests confirmed that nitrogen doping was an ... -
A Novel Decentralized Game-Theoretic Adaptive Traffic Signal Controller: Large-Scale Testing
(MDPI, 2019-05-17)This paper presents a novel de-centralized flexible phasing scheme, cycle-free, adaptive traffic signal controller using a Nash bargaining game-theoretic framework. The Nash bargaining algorithm optimizes the traffic signal ... -
Numerical Analysis of Signal Response Characteristic of Piezoelectric Energy Harvesters Embedded in Pavement
(MDPI, 2020-06-18)Piezoelectric pavement energy harvesting is a technological approach to transform mechanical energy into electrical energy. When a piezoelectric energy harvester (PEH) is embedded in asphalt pavements or concrete pavements, ... -
Numerical simulation of a free fall penetrometer deployment using the material point method
(2020-06)Free Fall Penetrometer (FFP) testing consist of a torpedo-shaped body freefalling into a soil target. The use of this type of device is becoming popular for the characterization of shallow sediments in near-shore and ... -
Observations of sesquiterpenes and their oxidation products in central Amazonia during the wet and dry seasons
(European Geophysical Union, 2018-07-23)Biogenic volatile organic compounds (BVOCs) from the Amazon forest region represent the largest source of organic carbon emissions to the atmosphere globally. These BVOC emissions dominantly consist of volatile and ... -
Occupational Safety and Health Concerns in Logging: A Cross-Sectional Assessment in Virginia
(MDPI, 2017-11-15)Increased logging mechanization has helped improve logging safety and health, yet related safety risks and concerns are not well understood. A cross-sectional study was completed among Virginia loggers. Participants n = ... -
Occurrence of Free Amino Acids in the Source Waters of Zhejiang Province, China, and Their Removal and Transformation in Drinking Water Systems
(MDPI, 2019-12-24)Free amino acids (FAAs) are key components of the global nitrogen cycle and important disinfection byproduct (DBP) precursors. The knowledge gap of FAA occurrence in source and engineered water is discussed in this paper. ... -
A One-Dimensional Model for Turbulent Mixing in the Benthic Biolayer of Stream and Coastal Sediments
(2020-12)In this paper, we develop and validate a rigorous modeling framework, based on Duhamel's Theorem, for the unsteady one-dimensional vertical transport of a solute across a flat sediment-water interface (SWI) and through the ... -
One-pot synthesis of high-performance Co/graphene electrocatalysts for glucose fuel cells free of enzymes and precious metals
(The Royal Society of Chemistry, 2015-05-01)A facile recipe has been developed to prepare three-dimensional nanoarchitectures of nitrogen-doped graphene loading Co nanoparticle hybrids (Co/NG). The hybrids show an outstanding electrocatalytic activity for glucose ... -
Opportunistic Premise Plumbing Pathogens: Increasingly Important Pathogens in Drinking Water.
(MDPI, 2015-06-09)Opportunistic premise plumbing pathogens are responsible for a significant number of infections whose origin has been traced to drinking water. These opportunistic pathogens represent an emerging water borne disease problem ... -
An Optimal Constrained Pruning Strategy for Decision Trees
(INFORMS, 2009)This paper is concerned with the optimal constrained pruning of decision trees. We present a novel 0-1 programming model for pruning the tree to minimize some general penalty function based on the resulting leaf nodes, and ...
