Puzzling the 120-cell

open access: yes, 2015
We introduce Quintessence: a family of burr puzzles based on the geometry and combinatorics of the 120-cell. We discuss the regular polytopes, their symmetries, the dodecahedron as an important special case, the three-sphere, and the quaternions. We then

Printed Interconnects for Heterogeneous Systems Integration on Flexible Substrates

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Key components (sensors, energy devices, communication devices, computing chips, and interconnects) of flexible hybrid electronic (FHE) system connected via conductive printed metal tracks. The figure in the insets shows out‐of‐plane printed interconnects providing opportunities for lithography‐free formation of VIAs, in‐plane access of UTCs pads, and ...

Silicon‐Integrated Next‐Generation Plasmonic Devices for Energy‐Efficient Semiconductor Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Silicon (Si)‐integrated plasmonics offer a pathway to next‐generation, energy‐efficient semiconductor applications. This review highlights advances using complementary metal–oxide–semiconductor (CMOS)‐compatible materials like transparent conductive oxides and novel architectures, particularly coupled hybrid plasmonic waveguides (CHPWs).

Room‐Temperature Tuning of Electrical Conductivity in Single MoS2 Flakes via Nanoscale Amorphization by Focused Ion Beam

open access: yesAdvanced Materials Technologies, EarlyView.
Focused ion beam (FIB) patterning enables on‐chip amorphization of high‐aspect ratio MoS2 monolayers into complex geometries with tunable electrical properties. By controlling the ion dose, conductive pathways as narrow as 700 nm are formed, allowing precise modulation of local conductivity.
