Gradient optical diffraction tomography

Communications Physics
Optical diffraction tomography (ODT) reconstructs the 3D refractive index (RI) distribution of transparent microsamples using angle-scanned holographic complex field measurements, enabling quantitative and label-free 3D imaging.

Development of micromechanical model of asphalt mixture in complex form for dynamic modulus characterization

Frontiers in Materials
Asphalt mixture is a multiphase composite viscoelastic material, with its fundamental viscoelastic properties primarily determined by its material composition and internal microstructure. The application of composite micromechanics and the development of

Whisker-reinforced ceramic composites for heat engine components [PDF]

Much work was undertaken to develop techniques of incorporating SiC whiskers into either a Si3N4 or SiC matrix. The result was the fabrication of ceramic composites with ever-increasing fracture toughness and strength. To complement this research effort,

3D Customized Silica‐Based AFM Probes Fabricated by Selective Laser Etching

Small Methods, EarlyView.
Selective laser etching (SLE) enables the monolithic fabrication of customized, fully 3D silica AFM probes integrating both cantilever and tip with controlled 3D geometries. The process allows the production of either sharp or spherical tips with high design flexibility, reproducibility, and yield.

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

Small Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Cement Lines are Stiffer and Harder than Bone but Exhibit Different Mineral–Mechanics Relationships due to Thicker and Shorter Mineral Particles

Small Structures, EarlyView.
Bone's complex hierarchical structure contains many internal interfaces, including the cement line (CL) around osteons. This article shows that the CL is stiffer and harder than surrounding bone but has different mineral–mechanics relationships. These findings challenge the view of the CL as a soft, protective interface and provide insights for ...

Predicting the Tensile Performance of 3D-Printed PE Fibre-Reinforced ECC Based on Micromechanics Model

Buildings
To elucidate the influence of the extrusion-based 3D printing of concrete on the tensile performance of polyethylene fibre-based engineered cementitious composites (PE-ECC), quantitative analyses of reinforcing filament alignment and pore morphology were
