Polarizability of noninteracting 2D Dirac electrons has a $1/\sqrt{qv\ensuremath{-}\ensuremath{\omega}}$ singularity at the boundary electron-hole excitations. The screening this by long-range electron-electron interactions is usually treated within random phase approximation. latter exact only in limit $N\ensuremath{\rightarrow}\ensuremath{\infty}$, where $N$ ``color'' degeneracy. We find that ladder-type vertex corrections become crucial close to threshold as ratio $n$th order ladder term...
The structural and transport properties of thin FePc films various thickness deposited onto glass substrates have been studied at several temperatures. studies show that the belong to monoclinic system β-phase. This structure is confirmed by infrared absorption analysis. dark electrical resistivity was found decrease with increasing film thickness. Graphical representation as a function reciprocal temperature yields two distinct linear parts indicating in turn existence activation energies ....
Irreversible electroporation (IRE) is a novel technique that deals with killing undesirable cells, mainly cancer directly without using any cytotoxic drugs. Commonly in this very high electric field up to 1000 V/cm used but for short exposure time (nanoseconds). Low fields (LEFs) are before internalize molecules and drugs inside the cells (electroendocytosis) not cells. The aim of work determine ability LEFs kill (Hela cells). Physics idea making energy equivalent IRE energy. Four protocols...
