3D-Printed Micro-Blades Beat Tissue Lasers

3D Printing Zero-Electricity Mechanical Logic

A technical breakdown of a Materials Horizons paper on reversible digital mechanics: flexural mechanical integrated circuits, bistable memory, AND logic, impedance matching, energy flow, and microscale fabrication paths for powerless mechanical computing. DOI: https://doi.org/10.1039/d5mh00509d

Scalable 3D Achromatic Metalenses for VR

A technical breakdown of a Nature Communications paper on 3D RGB achromatic metalenses for near-eye VR displays, covering differentiable library-based inverse design, two-photon-lithography meta-atoms, nanoimprint scalability, and OLED-panel integration. DOI: https://doi.org/10.1038/s41467-026-73103-2

2PP Polymer Lenses for Hard X-Rays

A technical breakdown of additively manufactured polymer compound refractive lenses for hard X-ray focusing, comparing projection micro-stereolithography and 2PP fabrication, at-wavelength metrology, and a 65-element CRL array demonstrated at 15 keV. DOI: https://doi.org/10.3390/photonics13040341

3D-Printed Micro-Blades Beat Tissue Lasers

A technical breakdown of 2PP-printed multi-tiered microDicer blade arrays for protein-preserving tissue microdissection, comparing mechanical microdissection against LCM for spatial proteomics at 10-20 micrometer resolution. DOI: https://doi.org/10.64898/2025.12.12.694048

Printing Microscopic Warp Bubbles

A technical breakdown of a controversial 2021 paper that uses worldline numerics on custom Casimir cavities to argue for a nanoscale energy distribution qualitatively similar to the Alcubierre warp metric, focusing on the 2PP-fabricated test geometry, the vacuum-energy modeling, and what this does and does not imply experimentally.
