Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
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 ...

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

High aspect ratio nanoparticles in nanotoxicology

Integrated Environmental Assessment and Management, 2007
In this Learned Discourse, we introduce nanotoxicology and note that little information is available on the role of aspect ratio in nanomaterial toxicity. Aspect ratio has implications for clearance from the lungs and for phagocytic cells such as the macrophage.

Simulations of high‐aspect‐ratio jets

International Journal for Numerical Methods in Fluids, 2002
AbstractThere are many practical situations when jets are emanating from non‐axis‐symmetric apertures, yet numerical simulations of such three‐dimensional jets are scarce and most of them have failed to reproduce some of the unique flow features. Examples of this type of jets are gas leaks from flanges.

Aspect-ratio-controlled synthesis of high-aspect-ratio gold nanorods in high-yield

Current Applied Physics, 2009
Abstract We describe a modified seed-mediated synthesis of high-aspect-ratio gold nanorods controlling the aspect ratio with variation of pH in the growth solution. By adding various amounts of sodium hydroxide, pH in the growth solution was controlled from 1.29 to 7.06 in the presence of nitrate anions.

Controlled Collapse of High‐Aspect‐Ratio Nanostructures

Small, 2011
AbstractCapillary‐force‐induced collapse of high‐aspect‐ratio (HAR) micro‐ and nanostructures is common in the evaporation–drying process and a number of applications based on the collapse have been proposed. However, the collapse of small HAR structures is usually uncontrollable, which has prevented it from being used in engineering applications. Here,
