Accessibility and Mechanical Stability of Nanoporous Zinc Oxide and Aluminum Oxide Coatings Synthesized via Infiltration of Polymer Templates

Article describes how the conformal nanoporous inorganic coatings with accessible pores that are stable under applied thermal and mechanical stresses represent an important class of materials used in the design of sensors, optical coatings, and biomedical systems. Authors synthesize porous AlOx and ZnO coatings by the sequential infiltration synthesis (SIS) of two types of polymers that enable the design of porous conformal coatings.

Effect of Laser Shock Peening Parameters on Residual Stresses and Corrosion Fatigue of AA5083 (open access)

Effect of Laser Shock Peening Parameters on Residual Stresses and Corrosion Fatigue of AA5083

Article examining Aluminium alloy 5083 subjected to Laser Shock Peening both with (LSP) and without protective coating (LPwC) at multiple pulse densities. A second LPwC treatment was conducted fully submersed under water, in addition to the standard laminar water flow condition. Results show that compressive residual stresses were generated in all cases, although their character varied depending on the peening strategy and method of confinement.

Experimental Validation of Diffraction Lithography for Fabrication of Solid Microneedles (open access)

Experimental Validation of Diffraction Lithography for Fabrication of Solid Microneedles

Article states that microneedles are highly sought after for medicinal and cosmetic applications. However, the current manufacturing process for microneedles remains complicated, hindering its applicability to a broader variety of applications. This experimental study enables the shapes and mechanical properties of the microneedles to be predicted in advance for mass production and wide practical use for biomedical or cosmetic applications.
