This paper presents an exploratory study of the binding interactions of xenon with the surface of several different proteins in the solution and solid states using both conventional and hyperpolarized (129)Xe NMR. The generation of hyperpolarized (129)Xe by spin exchange optical pumping affords an enhancement by 3-4 orders of magnitude of its NMR signal. As a result, it is possible to observe X...

In this research effect of synthesis method of magnesium aluminate as support of Ni catalysts at the reverse water gas shift (RWGS) reaction was evaluated. The RWGS reaction is applied in Carbon Dioxide Hydrogenation to Form Methanol via a Reverse Water-Gas Shift Reaction (CAMERE) process for the transformation of CO2 into methanol. The MgAl2O4 supports were prepared by sol-gel (M1), surfactant...

In this research, Quantum-mechanical calculations were performed at the HF method with the 6-31+G*basis set and at the B3LYP method with the 6-31+G* basis set in the gas phase and five solvents such as water, DMSO, methanol, ethanol and dichloromethane at six temperatures. According to these theoretical results of IR, we extracted thermo chemical parameters such as enthalpy (∆H Kcal/mol), Gibbs...

OBJECTIVES To examine the impact of pulse oximetry on the use of arterial blood gas and other laboratory determinations and to examine predictors of the use of arterial blood gas measurements. DESIGN Before (preoximetry)/after (postoximetry) study. SETTING Thirty-bed multidisciplinary critical care unit. PATIENTS Consecutive admissions of 300 patients (150 before and 150 after oximetry). ...

Using ambient pressure X-ray photoelectron spectroscopy (APXPS) and mass spectrometry (MS) while varying the temperature, we were able to directly understand how sequence of exposing reactant gases, CO2 H2, influenced surface species reverse water–gas shift reaction product formation on Ni(100). When first dosing at room temperature (RT), Ni(100) shows a significant amount oxide due spontaneous...
