About

Gelu Costin is a materials scientist whose research focuses on the intersection of nanotechnology, mineralogy, and sustainable energy. His most prominent work explores the exfoliation of naturally occurring silicates into two-dimensional (2D) structures, a breakthrough that opens new pathways for energy harvesting from abundant, low-cost minerals. In his highly cited 2023 paper, Costin demonstrated that a device made from these 2D d-silicates can generate up to ∼400 mV of voltage through simple mechanical motion, effectively turning common rocks into functional energy harvesters. This work, which has already garnered 18 citations, positions him at the forefront of green nanotechnology. By bridging fundamental mineral science with applied device engineering, Costin’s contributions offer a scalable, environmentally friendly alternative to traditional energy harvesting materials. His research not only challenges the conventional reliance on synthetic 2D materials but also highlights the untapped potential of Earth’s natural resources. For students and researchers alike, Costin’s work is a compelling example of how rethinking common minerals can lead to transformative technologies in the quest for sustainable energy solutions.
