Join the MIT ILP Leading Edge webinar, New technologies for improved mining operations, to explore how emerging technologies and automation are transforming the mining industry. Learn how the integration of data analytics and digital twins is advancing toward autonomous operations and real-time control systems powered by sensor data.
The MIT Center for Advanced Virtuality (MIT Virtuality for short) pioneers innovative experiences using technologies of virtuality — computing systems that construct imaginative experiences atop our physical world. Our approach to engineering and creative practices pushes the expressive potential of technologies of virtuality and simulates social and cognitive phenomena, while intrinsically considering their social and cultural impacts. This talk focuses on an important aspect of such technologies: virtual selves. Indeed nearly early everyone these days uses virtual identities, ranging from accounts for social media and online shopping to avatars in videogames or virtual reality. Given the widespread and growing use of such technologies, it is important to better understand their impacts and to establish innovative and best practices. In this talk, Harrell explores how our social identities are complicated by their intersection with extended reality technologies, videogames, social media, and related digital media forms. With an emphasis on equity, Harrell will explore how virtual identities both implement and transform persistent issues of class, gender, sex, race, ethnicity, and the dynamically construction social categories more generally.
Lithographic nanofabrication is often limited to successive fabrication of two-dimensional (2D) layers. We present a strategy for the direct assembly of 3D nanomaterials consisting of metals, semiconductors, and biomolecules arranged in virtually any 3D geometry. We used hydrogels as scaffolds for volumetric deposition of materials at defined points in space. We then optically patterned these scaffolds in three dimensions, attached one or more functional materials, and then shrank and dehydrated them in a controlled way to achieve nanoscale feature sizes in a solid substrate. We demonstrate that our process, Implosion Fabrication (ImpFab), can directly write highly conductive, 3D silver nanostructures within an acrylic scaffold via volumetric silver deposition. Using ImpFab, we achieve resolutions in the tens of nanometers and complex, non–self-supporting 3D geometries of interest for optical metamaterials.
