Saint Jean Carbon Inc. (TSXV:SJL) announced that the first measurements of its graphene nanomaterials have been completed. The measurements were done with the help of researchers at the University of Western Ontario.
As quoted in the press release:

The tests were performed at room temperature with a magnetometer obtaining superparamagnetic phases. The material tested is 99.9999% cg with zero iron (Fe) reporting.
The magnetic torque or turning force in a material is caused by the spin and orbital momentum states of its electrons. Materials that contain unpaired electrons spinning in the same direction, such as Carbon, are called paramagnetic. When an external magnetic field is applied the electrons align in the same direction as the external field. When the external force is switched off the electrons return to their former state. In certain materials, such as the carbon-based graphene tested by Western, the susceptibility to this paramagnetic effect whereby electrons can flip between positive, negative and neutral states is much larger, hence the ‘super’ in the name.
In the biomedical field for example, various ‘contrast mediums’ (or contrast agents) are used to illustrate the structures of fluids within the body in medical imaging. Outside the biomedical field the switching qualities have applications in products such as advanced recording media; semiconductor technology; in advanced battery power storage capabilities and in particular the extensive field of room-temperature superconductors. Superconductors are materials that conduct electricity with zero resistance. The closer to room temperature this can be achieved the more extensive the potential applications.
The Company believes the significance of these confirmed superparamagnetic observations in its graphene products cannot be understated.
