Winners of the 2023 VINSE Summer Image Competition
VINSE is excited to unveil the twelve winning images from our 2023 summer image competition. Since 2017, VINSE celebrates the work of our researchers, seeking images of materials or devices that have been fabricated, characterized or imaged using VINSE equipment with an annual image competition. Congratulations to this year’s winners. Each will receive a $250 cash prize and will have their art displayed in the Engineering Science Building.
