The Fabrication of Superhydrophobic Coatings Using Food‐Grade Wax Dispersions

Advanced Materials Interfaces, EarlyView.
A method is presented for creating superhydrophobic materials using a simple mixture of food‐grade wax and solvent. By varying the solubility and dispersibility of the wax as the solvent is replaced, superhydrophobic coatings can be achieved on different substrates using spray coating.

Non-Linear Unit Root Properties of Crude Oil Production [PDF]

While there is good reason to expect crude oil production to be non-linear, previous studies that have examined the stochastic properties of crude oil production have assumed that crude oil production follows a linear process.

Antifouling Surface‐Attached Hydrogel Nanocoatings Redefined: Green Solvent‐Based, Degradable, and High‐Performance Protection Against Foulants

Advanced Materials Interfaces, EarlyView.
An ultrathin surface‐attached hydrogel coating is introduced that, unlike the best antifouling coatings so far, consists of hydrophilic, non‐charged, green solvent‐based monomers. It effectively renders the surfaces of medical devices stealth toward proteins, a clinical strain of MRSA and blood while offering on‐demand degradability to regenerate the ...

Effect of pipe diameter on heat transfer characteristics of waxy crude oil pipeline during shutdown

Case Studies in Thermal Engineering, 2020
Additional specific heat capacity method and momentum source term method are used to establish the mathematical model of the heat transfer process in different diameter waxy crude oil pipeline, and the finite volume method is used to solve the ...

Enhancing Plasma Electrolytic Oxidation (PEO) Coatings on Magnesium Alloys: The Critical Role of Surface Pretreatments

Advanced Materials Interfaces, EarlyView.
This review explores how various surface pretreatment methods—such as heat treatment, severe plastic deformation, laser modification, immersion, and cold spray—enhance the performance of PEO coatings on magnesium alloys. The study highlights how these pretreatments influence coating microstructure, adhesion, and corrosion resistance, offering new ...

Crude Oil Price Volatility and the Nigerian Economy

International Journal of Energy Economics and Policy
This research analyzed crude oil price volatility and the Nigerian economy for the period 1990:Q1-2023:Q4. The independent variables were crude oil price, exchange rate and oil revenue while the dependent variables were GDP, government revenue ...

Multivariate Forecasting of Crude Oil Spot Prices using Neural Networks [PDF]

arXiv, 2018
Crude oil is a major component in most advanced economies of the world. Accurately predicting and understanding the behavior of crude oil prices is important for economists, analysts, forecasters, and traders, to name a few. The price of crude oil has declined in the past decade and is seeing a phase of stability; but will this stability last?

Consumption and Hedging in Oil Importing Developing Countries [PDF]

We study the consumption and hedging strategy of an oil-importing developing country that faces multiple crude oil shocks. In our model, developing countries have two particular characteristics: their economies are mainly driven by natural resources and ...

Well‐Defined Poly(HPMAm) Brushes via Surface‐Initiated RAFT Polymerization; A Mixed‐Chain Transfer Agent (CTA) Approach

Advanced Materials Interfaces, EarlyView.
A simple method relying on surface‐initiated RAFT polymerization is presented using a mixed‐chain transfer agent (mixed‐CTA) approach to grow well‐defined poly(HPMAm) brushes with precise control, achieving >70 nm thickness in 4 h at moderate temperature, 50 °C. Abstract Over three decades, efforts to prevent non‐specific protein adsorption on surfaces

Formulation of best-fit hydrophile/lipophile balance-dielectric permittivity demulsifiers for treatment of crude oil emulsions

Egyptian Journal of Petroleum, 2016
The commerce of crude oil depends heavily on its water and salt contents usually referred to as Basic Sediments and Water (BS&W), which is co-produced with the crude oil in the form of emulsion.
