On the Rigidity and Mechanical Behavior of Triply Periodic Minimal Surfaces‐Based Lattices: Insights from Extensive Experiments and Simulations

Advanced Engineering Materials, EarlyView.
This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

F-theory on quotients of elliptic Calabi-Yau threefolds

Journal of High Energy Physics, 2019
In this work we consider quotients of elliptically fibered Calabi-Yau threefolds by freely acting discrete groups and the associated physics of F-theory compactifications on such backgrounds.

Effect of Acrylic Structural Adhesive as a Joint Reinforcement on Film Deformation during the Thermoforming Process for In‐Mold Electronic Devices

Advanced Engineering Materials, EarlyView.
In‐mold electronics (IME) enables the integration of circuits into more complex scenarios, yet the key challenge remains ensuring a fully functional device. This study investigates how the presence of structural adhesives can improve the performance and functionality of IME devices, addressing key challenges in device integration.

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

Advanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave
