Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Effects of Adulteration on Diesel Oil with Kerosene Fuel in Ghana

Journal of Applied Sciences and Environmental Management, 2019
This research was carried out to estimate the proportional mixtures of diesel and kerosene that easily shows the incidence of fuel adulteration. Two samples (kerosene and diesel) were obtained from a base stock at Tema Oil Refinery and the purity for ...

Efficient Management of Sewage Sludge from Urban Wastewaters with the Addition of Inorganic Waste: Focus on Rheological Properties

Clean Technologies, 2022
Sewage sludge (SS) from urban wastewater treatment is still an environmental, economic, and social problem. Current SS management is not consensual, and more alternatives are required to recover some valuable compounds, such as nutrients and organic ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Laboratory investigation of the influence of fractures on CO2 flooding

Frontiers in Earth Science, 2022
CO2 injection is a promising method for low-permeability reservoirs. CO2 is much easier to inject underground compared with water. The solubility of CO2 in oil decreases the oil density and viscosity, leading to an enhancement of the oil recovery.
