Aluminum Al possesses unoccupied orbitals and is a powerful electrophile (electron deficient species). Suggest Corrections 8 Similar questions Q. Why does boron trifluoride behave as a Lewis acid? Q. Why nh4+ is a lowery bronsted acid despite not being a lewis acid Q. Why is NaH not a lewis...
All Al-containing catalysts have better sulfur-tolerance than the Al-free one, which is attributed to that (1) high catalytic activity reduces the proportion of BT-deactivated catalyst; (2) Al3+ site might provide additional active sites; (3) electron-deficient Pt delta+ promotes the BT ...

2021). The antioxidant effect of taurine is associated with an improvement of the mitochondrial function, as it stimulates the mitochondrial protein synthesis and enhances the activity of the electron transfer chain (Bhattacharjee et al. 2021). Also, taurine regulates the intracellular calcium ...

A representative electron micrograph of prefrontal cortex of all the rat groups showing nucleus is shown inFigure 7. Normal nucleus with double-layered nuclear membrane, nucleoli, and well-distributed chromatin material could be observed in the control group of rats (Figure 7A). Administration of D...
The deposited layer is polycrystalline, originating a ring electron diffraction pattern (see Figure 7c). Since all reflections appearing in the SAED pattern could be indexed according to the Al structure, it was concluded that no additional phases were present. Furthermore, the only structural ...
