InfoMat, EarlyView.Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures
Laser &Photonics Reviews, EarlyView.A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, EarlyView.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

Modeling the Elastic Recovery of PET Bottles via a Free‐Blowing of Preforms Campaign
Polymer Engineering &Science, EarlyView.From free‐blown preforms to mechanical properties. ABSTRACT This study aims to quantify the elastic properties induced by biaxial stretching at different temperatures in order to simulate the complete process including the final elastic recovery. The elastic modulus is identified from geometric measurements obtained during free‐blowing experiments. PET

Microfluidic Capillary Arrays for Pixelated Control of Multimaterial Flows
Small, EarlyView.A 3D‐printed pixellated capillary array maps up to thousands of fluid inputs into arbitrary multimaterial flow cross‐sections. Automated manifold design and laminar scaling are used to amplify printing resolution orders of magnitude, generating microscale fluidic control from printed elements, enabling designed microflows for potential use in ...
