Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

open access: yesAdvanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Dynamic distance-based shape features for gait recognition

open access: yes, 2014
We propose a novel skeleton-based approachto gait recognition. The core of our method consists ofemploying the screened Poisson equation for construct-ing a family of smooth distance functions associatedwith a given shape.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Recognition of Geometrical Shapes by Dictionary Learning

open access: yes2025 International Conference on Artificial Intelligence, Computer, Data Sciences and Applications (ACDSA)
Dictionary learning is a versatile method to produce an overcomplete set of vectors, called atoms, to represent a given input with only a few atoms. In the literature, it has been used primarily for tasks that explore its powerful representation capabilities, such as for image reconstruction. In this work, we present a first approach to make dictionary

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

open access: yesAdvanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Micropatterning of single endothelial cell shape reveals a tight coupling between nuclear volume in G1 and proliferation

open access: yes, 2008
Shape-dependent local differentials in cell proliferation are considered to be a major driving mechanism of structuring processes in vivo, such as embryogenesis, wound healing, and angiogenesis.

Rabbit Skull Shape: Three‐Dimensional Geometric Morphometric Analysis

open access: yesVeterinary Medicine and Science
The objective of the present study was to analyse the three‐dimensional shape of the cranium models of New Zealand rabbits and to determine the effects of sex on shape. To this end, a total of 12 rabbit craniums were used (six female and six male). After
