After the debris particle is formed, the system transitions in fact to a three-body contact configuration. The loading conditions are then changed and the critical length scale d* might thus assume a different value upon rolling contact. Furthermore, atoms can be removed at the interface by ...
The formation water and associated gas can hinder the pyrolysis of heavy components, while the minerals in the formation can accelerate the pyrolysis process. The relationship between the carbon atoms number in each of the most consumed hydrocarbon molecule and different LTO reaction conditions has ...
The different reactivities of these oxygenate species under reaction conditions (Table 1) can also explain the main results of the present study. Table 1 A compilation of the chemical reactions describing DRM activity on the nickel catalyst Full size table Initially, CO2 dissociation leads to the f...
Oxygen evolution reaction (OER) is a crucial half-reaction in electrochemical water splitting, and efficient and durable electrocatalysts are required to improve the sluggish OER kinetics. However, the inevitable formation of chemical oxygen species (COSs) in the OER process heavily impacts the reaction...
Combining classical molecular dynamics simulations with high level, multiconfigurational ab initio calculations, we demonstrate that even relatively mild collisions between ground state oxygen molecules can readily lead to the formation of highly reactive singlet oxygen molecules via a novel "ladder climbing...
Hydrocarbon concentrations decrease during ozone depletion events due to reaction with halogen atoms. The rate of ozone destruction depends on whether the addition of Br to C 2 H 4 and C 2 H 2 yields inert products or intermediates from which Br can be regenerated. Bromine and HCHO are ...

The aim of this work was to synthesize a green nanoparticle SnCuO@FeO nanocomposite core–shell to break oily water emulsions during petroleum-enhancing production processes as an alternative to chemical and physical processes. In this study, eight bacte
Its functionality stems from a conductive filament (CF), which initially forms inside the oxide layer to provide the electronic conduction pathways. The RRAM can then switch between a high resistance (HRS) and a low resistance state (LRS), as the CF evolves, ruptures and reforms between the ...
