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... -
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... -
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... -
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... -
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... -
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... -
Highly Luminescent, Triple- and Quadruple-Stranded, Dinuclear Eu, Nd, and Sm(...
The bis(β-diketone) ligands 1,3-bis(3-phenyl-3-oxopropanoyl)benzene, H2L1 and 1,3-bis(3-phenyl-3-oxopropanoyl) 5-ethoxy-benzene, H2L2, have been prepared for the examination of... -
Dendrimer-Supported Oligothiophene Synthesis: Aliphatic Ether Dendrimers in ...
The first dendrimer-supported synthesis of oligothiophenes is reported. The dendrimer serves both as a solubilizing group and a “handle” to facilitate the iterative synthesis of... -
Predicting Bioavailability of Sediment-Associated Organic Contaminants for <i...
Biota-sediment accumulation factors (BSAF) were calculated for Diporeia spp. and oligochaete worms exposed to polychlorinated biphenyls (PCBs) and polycyclic aromatic... -
CAUTION: Popular "Benchmark" Data Sets Do Not Distinguish the Merits of 3D QS...
The quality of 3D QSAR models obtained using extremely simple descriptors was examined for nine popular data sets, including the well-known set of 31 steroids, which for 20... -
Total Synthesis of the Ristocetin Aglycon
The first total synthesis of the ristocetin aglycon is described employing a modular and highly convergent strategy. An effective 12-step (12% overall) synthesis of the ABCD... -
Discovery of and Mechanistic Insight into a Ligand-Modulated Palladium-Cataly...
We describe the discovery of a new N-heterocyclic carbene-modulated Pd catalyst for the Wacker oxidation that does not require molecular oxygen but instead uses TBHP as a... -
A New Highly Asymmetric Chelation-Controlled Heck Arylation
This communication describes the development of a new highly asymmetric chelation-controlled Heck arylation. The methodology permits formation of 2-aryl-2-methyl cyclopentanones... -
Carbon Dioxide Sequestration in Cement Kiln Dust through Mineral Carbonation
Carbon sequestration through the formation of carbonates is a potential means to reduce CO2 emissions. Alkaline industrial solid wastes typically have high mass fractions of... -
Highly selective cobalt-catalyzed hydrovinylation of styrene
: The hydrovinylation reaction is a codimerization of a 1,3-diene or vinyl arene and ethene with great potential for fine chemicals and pharmaceuticals. For the first time,... -
Atomic Layer Deposition of Metal Tellurides and Selenides Using Alkylsilyl Co...
Atomic layer deposition (ALD) of metal selenide and telluride thin films has been limited because of a lack of precursors that would at the same time be safe and exhibit high... -
