Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Spatially Controlled 3‐D Multiplexed Aptamer Patterning in Hydrogels

open access: yesAdvanced Materials Interfaces, EarlyView.
A hydrogel platform based on norbornene‐functionalized polyvinyl alcohol enables high‐resolution, 3‐D multiplexed patterning of DNA aptamers via two‐photon polymerization. Two distinct aptamers are covalently immobilized with single micron‐scale precision across the x, y, and z dimensions.

Optimization-based smoothing algorithm for triangle meshes over arbitrarily shaped domains [PDF]

open access: yesarXiv, 2014
This paper describes a node relocation algorithm based on nonlinear optimization which delivers excellent results for both unstructured and structured plane triangle meshes over convex as well as non-convex domains with high curvature. The local optimization scheme is a damped Newton's method in which the gradient and Hessian of the objective function ...

A New Approach to an all Quadrilateral Mesh Generation over Arbitrary Linear Polygonal Domains for Finite Element Analysis [PDF]

open access: yes, 2014
This paper describes a scheme for finite element mesh generation of a convex, non-convex polygon and multiply connected linear polygon. We first decompose the arbitrary linear polygon into simple sub regions in the shape of polygons.These subregions may ...

Atomic‐Scale Mechanisms of Nucleation and Stabilization in CuCrO2 and CuFeO2 Delafossite Thin Films on Al2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, a combination of 4D STEM phase reconstructions via iterative electron ptychography, spectroscopy, and conventional STEM imaging reveals detailed insights into the nucleation mechanism for the stable growth of Cu‐based delafossites on Al2O3 using CuCrO2 and CuFeO2 films grown via MBE as examples.

A geometric mesh smoothing algorithm related to damped oscillations [PDF]

open access: yesarXiv, 2014
We introduce a smoothing algorithm for triangle, quadrilateral, tetrahedral and hexahedral meshes whose centerpiece is a simple geometric triangle transformation. The first part focuses on the mathematical properties of the element transformation. In particular, the transformation gives rise directly to a continuous model given by a system of coupled ...

Biomechanical and Displacement‐Related Considerations in the Design of a 3D‐Printed Composite Energy‐Storage‐and‐Return Prosthetic Foot

open access: yesAdvanced Materials Technologies, EarlyView.
For the first time, Continuous Fiber‐Reinforced 3D printing is used to fabricate a foot prosthesis, exploring the flexibility in the design space granted by additive manufacturing, evaluating computationally and experimentally the effect of different design features on the mechanical and biomechanical response of the material, to locally tune the ...
