The study reports some preliminary investigations on the template free synthesis of a scantly investigated polyaniline (PANI) derivative-Phenylenediamine (PDA) by template free method in the presence of Oxalic acid (OA) (dopant), using Ammonium Persulfate as oxidant. Polymerization of Phenylenediamine (PDA) was confirmed by the FT-IR as well as UV–visible studies. The morphology of Phenylenedia...

We consider free higher derivative theories of scalars and Dirac fermions in the presence a boundary general dimension. establish method for finding consistent conformal conditions these by removing certain primaries from spectrum. A rich set renormalization group flows between various is revealed, triggered deformations quadratic primaries. compute energy on hemisphere, show that $a$-theorem g...
