Generation of ROS mediated by mechanical waves (ultrasound) and its possible applications.

The thermal decomposition of 9,10 diphenylanthracene peroxide (DPAO) generates DPA and a mix of triplet and singlet molecular oxygen. For DPAO the efficiency to produce singlet molecular oxygen is 0.35.

Relativistic two-component geometric approximation of the electron-positron contribution to magnetic properties in terms of Breit-Pauli spinors.

An alternative approach for the calculation of the electron-positron (e-p) contribution to magnetic properties based on two-component Breit-Pauli spinors is presented. In it, the elimination of the small component scheme is applied to the inverse propagator matrix of e-p pairs. The effect of the positronic manifold is expressed as an operator acting on Breit-Pauli spinors.
