thermite compounds undergo an exothermic reduction-oxidation (redox) reaction as the aluminium reduces the number of electrons in the iron oxide atoms. More heat makes the reaction run faster, generating more heat, and so on. The result is molten iron and...
Kohn–Sham density functional theory is widely used in chemistry, but no functional can accurately predict the whole range of chemical properties, although recent progress by some doubly hybrid functionals comes close. Here, we optimized a singly hybrid
such as irregularities and heterogeneities, which may have an impact on how the material is used. Contrary to a smooth surface, topographical changes to a surface, such as random roughness, gratings, or isolated bumps, will change the adsorption process. An increase in surface...

According to the results, boron doping enhances the bond strength and wear resistance of diamond film and substrate. The higher wear resistance and bonding strength of boron-doped diamond film ensure that the boron-doped diamond inserts can withstand adhesive wear and impact. Lu et al [153] ...
It is undoubtedly an important way to solve the problem where the current MXene synthesis method contains F, which is not environmentally friendly and has a high energy consumption rate due to it searching for a suitable etchant to obtain a better etching effect at a lower temperature. Further...
electrons. The conductivity values of PANI, PANI@TiO2, PANI@Al2O3, and PANI@TiC were 1.457 S·cm−1, 1.029 S·cm−1, 0.921 S·cm−1, and 0.682 S·cm−1, respectively. Moreover, the CV and GCD were used to test the electrochemical behavior of the hybrid nanocomposites. The ...
We propose a new exactly solvable model of strongly correlated electrons. The model is based on a d – p model of the CuO 2 plane with infinitely large repulsive interactions on Cu-sites, and it contains additional correlated-hopping, pair-hopping and charge–charge interactions of electrons. ...
triple bond, in chemistry, a covalent linkage in which two atoms share three pairs of electrons, as in the nitrogen molecule, N2, or acetylene, C2H2.
While the quantum mechan- ics metaphor indicates that some tiny percentage of the time this will not occur, trials of poker hands are more akin to the motions of planets than the motions of electrons, and results are heavily skewed in favor of the predicted outcome. So while Einstein's ...
