Geometry Analysis of Two Photon Polymerized Microneedles—An Experimental and Simulated Approach

Journal of Applied Polymer Science, Volume 143, Issue 22, June 10, 2026.
This research investigates the mechanical stability of hollow, two‐photon‐polymerized microneedles for drug delivery. In an experimental setup, a steel stamp gradually compresses 1000 μm‐tall microneedles while recording their force–deformation response.

Joint Damage Effects on Axial Capacity of Cold‐Formed Steel Uprights: Experimental, Numerical, and Machine Learning Study

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study quantifies how beam‐to‐column joint damage alters the axial resistance and failure modes of cold‐formed steel (CFS) uprights used in industrial storage rack systems. Current design‐oriented assessments typically neglect the reduction of joint rotational stiffness and moment resistance caused by prior cyclic joint deterioration, which can ...
