Tailoring Anisotropic Wettability Using Micro-pillar Geometry

Colloids and Interface Science Communications, 2014
AbstractAnisotropic surfaces have great potential in important applications like microfluidic devices, lab-on-chip systems, micro-reactors, coatings and printings. Anisotropic wetting behavior on micro-pillars is of particular interest since micro-scale morphology on many natural anisotropic wetting surfaces are pillar-like structures. It is found that

Geometry assessment of ultra-short pulsed laser drilled micro-holes [PDF]

The International Journal of Advanced Manufacturing Technology, 2020
AbstractUltra-short pulsed laser ablation enables a defined generation of micro-holes. A parameter study on the ablation characteristics of copper clearly reveals a benefit for green wavelength with lower threshold fluence, simultaneously increasing the Rayleigh length.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
