Zn-mediated catalytic photoreduction of aldimines. One-pot synthesis and separation of meso and d,l C2 symmetrical diamines [PDF]

open access: yes, 2004
A new one-pot method for the synthesis and selective separation of 1,2-diamines is reported. The methodology, which involves the photoreduction of imines using catalytic amounts of zinc as a photosensitizer, allows the direct preparation and separation ...

Automated Alignment Powered by Computer Vision Streamlines the Two‐Photon Polymerization‐Based Micro 3D Printing of Multiscale and Multimaterial Structures

open access: yesAdvanced Intelligent Discovery, EarlyView.
Two‐photon polymerization enables high‐resolution microfabrication, but performing alignment when printing multiple structures is difficult. Here, we present a fast, robust, and open‐source protocol for automated alignment on Nanoscribe systems. Achieving ≈0.4 μm accuracy in under 5 s, our protocol reduces time and error in multimaterial printing. This
