In this study, the effect of fullerene electron mobility on the composition of paraphenylenediamine and stability was studied. Using quantum chemistry calculations, the first combination of paraffenylenediamine in a single-full-time region connected with fullerene through carbon atoms was reported. Experimental research was simulated and optimized using GIS software. Then the NBO calculations w...

We show how to include a chemical potential µ in perfect lattice actions. It turns out that the standard procedure of multiplying the quark fields Ψ, ¯ Ψ at Euclidean time t by exp(±µt), respectively, is perfect. As an example, the case of free fermions with chemical potential is worked out explicitly. Even after truncation, cutoff effects in the pressure and the baryon density are small. Using...

In this study, on the combination of chlorpromazine with two aromatic rings, halogens are attached to the rings, and changes in the angles and lengths of the ipsos are calculated. Calculations show that by changing the halogen based on the amount of electronegativity, the magnitude and variation of the angular lengths The lengths of the links also change in the following order. The angles of th...
