The Architecture of BaTiO3 Nanoparticles Synthesis via Temperature-Responsive for Improved Oil Recovery: A Molecular Dynamics Simulation and Core-Flooding Experimental Study

open access: yesCrystals
This research investigates the influence of various concentrations of BaTiO3 nanofluid on adsorption energy and improved oil recovery. BaTiO3 nanoparticles were successfully synthesized using a Sol-gel approach at temperatures of 400 °C, 500 °C, 800 °C ...

EFFECT OF THE APPLICATION OF MICROWAVE ENERGY ON THE REGENERATION OF THE ADSORBENT [PDF]

open access: yes, 2018
Today, energy conservation is a priority. This is due to the shortage of energy resources, the growth of their cost and global environmental problems. The production of compressed air is a wery costly and power-consuming process.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Adsorption and diffusion of H2O molecule on the Be(0001) surface: A density-functional theory study

open access: yes, 2011
Using first-principles calculations, we systematically study the adsorption behavior of a single molecular H$_{2}$O on the Be(0001) surface. We find that the favored molecular adsorption site is the top site with an adsorption energy of about 0.3 eV ...

Adsorption of Energy in Photocatalytic Reactors [PDF]

open access: yes, 1985
The dissociation of water to hydrogen and oxygen requires energy ∆G298 = 228 kJ/mole. By irradiating a semiconductor with light of energy greater than this amount, one may product electrons in the excited state and electron vacancies at the surface that can perform the photochemical reduction (2H+ + 2e− → 2H → H2) and oxidation (2OH− + 2+ → H2O2→ H2O +

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.
