HOPG – Highly Ordered Pyrolytic Graphite is a unique form of natural Graphite and is generally produced through expensive synthetic methods. It is characterized by a high degree of three-dimensional ordering and has the ability to repel magnetic fields. Occurring naturally could open up a new chapter in natural graphite applications in fields such as transportation and energy generation. In a recent report in the Journal of the American Chemical Society, researchers at Aoyama Gakuin University in Kanagawa, Japan outlined their work on using diamagnetic graphite to achieve real-time motion control which can move a magnetically levitating diamagnetic material without contact. The researchers used a focused laser, and alternatively direct sunlight, to adjust both the height and revolution speed of a diamagnetic disk. Their results could lead to lead to the development of maglev-based actuators and photothermal solar energy conversion systems. Applications could include a low-cost, environmentally friendly power generation system and a new type of light-driven transportation system. Samples recovered from Saint Jean’s claims were collected by following an appropriate chain-of-custody protocol that including recording their location using positioning coordinates. An initial inspection of the samples seemed to suggest geologic characteristics associated with Natural Diamagnetic or Highly Ordered Pyrolytic Graphite (HOPG). If additional exploration, research, and processing work confirms its possible presence and viability it could expand interest in natural graphite even further. see more at www.saintjeancarbon.com
