The need of heavy and unconventional crude oil as an energy source is increasing day by day, so does the importance of petroleomics: the pursuit of detailed knowledge of heavy crude oil. Crude oil needs techniques with ultra-high resolving capabilities to resolve its complex characteristics. Therefore, ultra-high resolution mass spectrometry represented by Fourier transform ion cyclotron resona...

The gas generative potential of the Cretaceous Cameo coal in the Piceance Basin, northwestern Colorado, was evaluated quantitatively by sealed gold tube pyrolysis. TheH/C andO/C elemental ratios show that pyrolyzed Cameo coal samples follow the Van Krevelen humic coal evolution pathway, reasonably simulating natural coal maturation. Kinetic parameters (activation energy and frequency factor) fo...

Numerous laboratory experiments have been performed in an attempt to mimic atmospheric secondary organic aerosol (SOA) formation. However, it is still unclear how close the aerosol particles generated in laboratory experiments resemble atmospheric SOA with respect to their detailed chemical composition. In this study, we generated SOA in a simulation chamber from the ozonolysis of αpinene and a...

Surface conditions on Mars are currently cold and dry, with water ice unstable on the surface except near the poles. However, geologically recent glacierlike landforms have been identified in the tropics and the midlatitudes of Mars. The ice has been proposed to originate from either a subsurface reservoir or the atmosphere. We present high-resolution climate simulations performed with a model ...

This paper presents multiple methods for predicting heavy/mediumduty vehicle fuel consumption based on driving cycle information. A polynomial model, a black box artificial neural net model, a polynomial neural network model, and a multivariate adaptive regression splines (MARS) model were developed and verified using data collected from chassis testing performed on a parcel delivery diesel tru...

The chemical analysis of caramel, formed upon heating of carbohydrates, remains a significant challenge due to the complexity of the resulting product mixture. Identification of the products formed upon heating of monosaccharides including fructose, mannose, galactose, arabinose and ribose is essential to understand the composition and properties of carbohydrate-rich processed foods. In this wo...

HDO and the D/H ratio are essential to understand Mars past present climate, in particular with regard evolution through ages of Martian water cycle. We here new modeling developments cycle LMD GCM. The study aims at exploring behaviour its sensitivity ice clouds formulation fractionation by condensation. Our GCM simulations compared observations provided Atmospheric Chemistry Suite (ACS) on bo...

Abstract Methane content in a coal seam is necessary parameter for evaluating bed gas, and it poses an environmental risk to underground mining activities. Keeping pace with comprehensive studies of 12 samples were selected from the Sitarampur block Raniganj Coalfield analysis. The Petrographic examination illustrated that significant values reactive macerals present demonstrate organic matter ...

Dissolved natural organic matter (DOM), particularly the low molecular weight DOM, can affect the performance of water treatment processes and serve as a main precursor of disinfection by-products (DBPs) during chlorination. In this study, electrospray ionization coupled to Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS) was used to characterize the low molecular wei...
