Abstract Although the deformation of Heisenberg algebra by a minimal length has become central tool in quantum gravity phenomenology, it never been rigorously obtained and is often derived using heuristic reasoning. In this study, we move beyond derivation deformed explicitly derive model discrete spacetime, which motivated gravity. Initially, investigate effects leading order Planckian lattice corrections demonstrate that they precisely match those suggested arguments commonly used...

L-asparaginato complexes of Copper(II), Zinc(II) and Cadmium(II) were synthesized from their respective metal oxide L-asparagine. These prepared characterized by content analysis, infrared, ultravioletvisible spectral studies, magnetic susceptibility measurement, thermal cyclic voltammetric measurement. Physico-chemical investigations reveal that [M(OOCCHNH2CH2CONH2)2], (M = Cu(II), Zn(II), Cd(II)) is the general formula for complexes. L-asparagine combines with oxides to form...

The electrochemical reduction of Cu(II) has been studied in aqueous Britton-Robinson (BR) buffer medium with glassy carbon electrode (GCE) at various pH values. It is observed that low values follows two-step while high it undergoes one-step process.
