Unregulated Emissions from a Heavy-Duty Diesel Engine with Various Fuels and ...
This study evaluated the effects of various combinations of fuels and emission control technologies on exhaust emissions from a heavy-duty diesel engine tested on an engine... -
Magnetic Fluorescent Delivery Vehicle Using Uniform Mesoporous Silica Spheres...
We synthesized uniform pore-sized mesoporous silica spheres embedded with magnetite nanocrystal and quantum dots. The magnetic separation, luminescent detection, and controlled... -
Remarkable Effect of Pore Size on the Catalytic Activity of Mesoporous Silica...
The catalytic activity of mesoporous silica (MCM-41) for the acetalization of cyclohexanone shows a volcano-shaped dependence on the pore diameter. The diameter of the... -
Polymorphic Packing Arrangements in a Class of Engineered Organic Crystals
Polymorphism occurs in the family of engineered cocrystals that form from N,N ‘-bis(p-X-phenyl)melamines (X = H, F, Cl, Br, I, CH3, and CF3) and barbital. X-ray powder... -
Modeling Active Capping Efficacy. 1. Metal and Organometal Contaminated Sedim...
Cd, Cr, Pb, Ag, As, Ba, Hg, CH3Hg, and CN transport through sand, granular activated carbon (GAC), organoclay, shredded tires, and apatite caps was modeled by deterministic and... -
Synthesis of Zinc Oxalate Coordination Polymers via Unprecedented Oxidative C...
The zinc oxalate coordination polymers Zn(ox)(Py)2 (1) and [methylpyridinium]2[Zn2(ox)3] (2) have been synthesized via unexpected oxidation of ethanol and oxidative coupling of... -
Fuel-Mercury Combustion Emissions: An Important Heterogeneous Mechanism and a...
An extensive examination of combustion gases containing trace amounts of mercury shows unambiguously mercury’s propensity for heterogeneous chemistry. Although additional... -
Novel Amphiphilic Conetworks Composed of Telechelic Poly(ethylene oxide) and ...
Amphiphilic conetworks (APCNs) containing covalently bonded hydrophilic poly(ethyleneoxide) (PEO) and hydrophobic polyisobutylene (PIB) have been synthesized by chain end... -
Prescribed Fire As a Means of Reducing Forest Carbon Emissions in the Western...
Carbon sequestration by forested ecosystems offers a potential climate change mitigation benefit. However, wildfire has the potential to reverse this benefit. In the western... -
Tunability of Supramolecular Kagome Lattices of Magnetic Phthalocyanines Usin...
Self-assembly of various phthalocyanine (Pc) molecules and a derivative on an epitaxial graphene monolayer (MG) has been investigated by means of in situ ultrahigh vacuum... -
Generation and Characterization of Four Dilutions of Diesel Engine Exhaust fo...
Exposure atmospheres for a rodent inhalation toxicology study were generated from the exhaust of a 2000 Cummins ISB 5.9L diesel engine coupled to a dynamometer and operated on a... -
Estimation of Volatile Emissions During the Excavation of Soil or Waste
A model is presented for estimating transient air emissions of volatile chemicals during excavation into a zone of contaminated soil or waste. Using measured in situ parameters,... -
Exergy: Its Potential and Limitations in Environmental Science and Technology
New technologies, either renewables-based or not, are confronted with both economic and technical constraints. Their development takes advantage of considering the basic laws of... -
Roles of Acetone-Conditioning and Lipid in Sorption of Organic Contaminants
Sorption of phenanthrene and 1-naphthol by a peat soil (PS) and its humic acid fractions (HAs) and humin (HM) was examined. Both phenanthrene and 1-naphthol consistently had... -
Organically Templated Linear and Layered Iron Sulfates
Linear and layered organically templated iron sulfates have been prepared under hydrothermal conditions. The linear iron sulfates, with the compositions... -
Water-Medium Clean Organic Reactions over an Active Mesoporous Ru(II) Organom...
Water−medium clean organic reactions including isomerization and hydrogenation were carried out over a Ru(II) mesoporous organometallic catalyst (Ru-MOC) synthesized based on... -
