AlignPCA‐2D: PCA‐reduced Euclidean vector alignment for 2D classification in cryo‐EM

Acta Crystallographica Section D, Volume 82, Issue 7, Page 727-739, July 2026.
We introduce AlignPCA‐2D, a PCA‐space Euclidean alignment method for rapid and interpretable 2D classification of cryo‐EM particle images. The approach preserves essential structural variability while greatly reducing computational cost, offering a lightweight alternative to existing large‐scale cryo‐EM classification pipelines.Cryogenic electron ...

Electroless Plating of PLA and PETG for 3D Printed Flexible Substrates

ECS Transactions, 2015
The NiP and Cu electroless metallization of 3D printed polymers is presented. The plating process is tested on suitable samples, which reproduce the printing morphologies used in the 3d printing of objects. An alkaline etching is used for both the polymers in order to modify the surface properties and enhance the adhesion and uniformity of the metallic
