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

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
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]
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
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 ...

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.
