Ligand discrimination and inhibition of heme iron autooxidation by myoglobin: Site-directed mutagenesis of a synthetic gene
… evolved under strong selective pressure to overcome the natural tendency of a free heme prosthetic group to bind carbon monoxide (CO) 1000-fold more tightly than atmospheric dioxygen (O$\sb2$). Without protein-directed discrimination between these ligand molecules, the basal production of CO …

FTIR studies of environmental effects on carbonmonoxymyoglobin
… this thesis, Fourier Transform Infrared Spectroscopy (FTIR) was used to study the interaction between the protein myoglobin (Mb), and substrate carbon-monoxide (CO), as a model system of control in protein-ligand systems. IR spectra of the CO molecule bound to Mb have been obtained as a function …

A comparison of the HI and CO velocity dispersions of nearby galaxies
… of galactic disks against gravitational collapse to form stars, in some star formation recipes, in studies of gas dynamics, and to determine how much turbulence there is in the interstellar medium. Atomic hydrogen (HI) dispersions have been used in the studies of star formation and …

Catalysis and reactor engineering for the electrochemical conversion of carbon dioxide to carbon monoxide
Carbon dioxide (CO₂) utilization processes have garnered significant interest to both mitigate anthropogenic greenhouse gas emissions and increase the revenue of many chemical and fuel production processes. Low-cost renewable electricity provides impetus for exploring electrochemical methods to …

Electrochemical Oxidation of Carbon Monoxide in Reformate Hydrogen for PEM Fuel Cells
<p>Carbon monoxide (CO) poisoning of platinum anode significantly decreases the performance of proton exchange membrane fuel cells (PEMFC). Various techniques studied to remove CO from source or mitigate CO poisoning have met with limited success due to fuel loss or increases infrastructure …

STUDIES ON THE REACTION OF HIGH-DOSE HYDROXOCOBALAMIN AND ASCORBIC ACID WITH CARBON MONOXIDE: IMPLICATIONS FOR TREATMENT OF CARBON MONOXIDE POISONING
… 1970’s we proposed that a reduced form of hydroxocobalamin should be capable of producing carbon dioxide (CO2) from carbon monoxide (CO) in blood, and that this conversion should be detectable. Using resonance raman spectroscopy we demonstrated that a mixture of hydroxocobalamin and ascorbic acid …

COMMUTER EXPOSURE TO AEROSOL POLLUTION ON PUBLIC TRANSPORT IN SINGAPORE
… of aerosol exposure is experienced during daily commuting trips due to the proximity to traffic. Improved understanding of the variability across transport modes and transportation choices is important for commuters and authorities. Mobile measurements of PM10, PM2.5, particle number (PN), black …

Emission Measurement of Air Pollutants from CNG-gasoline Bi-fuel Vehicles
… motor vehicles vary under different operating conditions, which will cause uncertainty in developing emission inventory. Natural gas (NG), considered as a “cleaner” fuel than gasoline, is increasingly being used to reduce combustion emissions, but the information is scarce about how much …

Effect of Carbon Monoxide-Releasing Molecule-3 on the Severity of Endothelial Dysfunction Due to Elevation of Hydrostatic Pressure in an In Vitro Model of Compartment Syndrome
Compartment syndrome (CS) is a surgical emergency caused by elevated pressure within a closed osseofascial compartment. It leads to microvascular dysfunction, limiting oxygen and nutrient delivery, gas exchange, resulting in cellular anoxia, muscle necrosis and cell death. Currently, the only …

Mid Infrared Investigation of Two Isomers of the CO-N2O van der Waals Complex
Infrared spectra in the carbon monoxide CO stretch region (~2150 cm−1) and in the nu3 asymmetric stretch region of N2O (~2223 cm−1) are assigned to the previously unobserved O-bonded form of the CO-N2O dimer (“isomer 2”). This van der Waals complex has a planar skewed T-shaped structure like that …
