, 2017 No Petroleum contributes significantly to our lives and will continue do so for many years to come. Petroleum derivatives supply more than 50% of the world's total supply of energy (Jarullah, 2011). Traditionally crude oil goes though fractional distillation to produce different grades of fuel such as gasoline, kerosene, diesel oil, etc. providing fuel

Beyond One-Step-Ahead Forecasting: Evaluation of Alternative Multi-Step-Ahead Forecasting Models for Crude Oil Prices [PDF]
Energy Economics. 40, 2013: 405-415, 2014 An accurate prediction of crude oil prices over long future horizons is challenging and of great interest to governments, enterprises, and investors. This paper proposes a revised hybrid model built upon empirical mode decomposition (EMD) based on the feed-forward neural network (FNN) modeling framework incorporating the slope-based method (SBM), which

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams
Advanced Functional Materials, EarlyView.Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

Crude oil desulfurization [PDF]
, 1982 High sulfur crude oil is desulfurized by a low temperature (25-80 C.) chlorinolysis at ambient pressure in the absence of organic solvent or diluent but in the presence of water (water/oil=0.3) followed by a water and caustic wash to remove sulfur and ...

Volatile hydrocarbons inhibit methanogenic crude oil degradation [PDF]
, 2014 Methanogenic degradation of crude oil in subsurface sediments occurs slowly, but without the need for exogenous electron acceptors, is sustained for long periods and has enormous economic and environmental consequences.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations
Advanced Functional Materials, EarlyView.Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Econometric Model Using Arbitrage Pricing Theory and Quantile Regression to Estimate the Risk Factors Driving Crude Oil Returns [PDF]
arXiv, 2023 This work adopts a novel approach to determine the risk and return of crude oil stocks by employing Arbitrage Pricing Theory (APT) and Quantile Regression (QR).The APT identifies the underlying risk factors likely to impact crude oil returns.Subsequently, QR estimates the relationship between the factors and the returns across different quantiles of ...

All‐Cellulose‐Based Photonic Glitters
Advanced Functional Materials, EarlyView.Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

How do mobility restrictions and social distancing during COVID-19 affect the crude oil price? [PDF]
arXiv, 2021 We develop an air mobility index and use the newly developed Apple's driving trend index to evaluate the impact of COVID-19 on the crude oil price. We use quantile regression and stationary and non-stationary extreme value models to study the impact.
