Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Entrainment in Refrigerated Air Curtains [PDF]
Refrigerated air curtains are used in supermarket display cases to keep warm ambient air from entering the refrigerator case. Entrainment of ambient air into the curtain by shear layer mixing contributes to both the sensible and the latent heat load on ...

Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Predicting Refrigerant Inventory of HFC 134a in Air Cooled Condensers [PDF]
Currently, the refrigerant inventory for vapor compression systems is determined using a costly trial and error procedure. An accurate computer model of the refrigerant in a system would reduce the time and expense of this process.

This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...
