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.

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 ...

Electronic Structure and Mechanical Properties of Ti5Si3

Journal of Experimental and Theoretical Physics, 2022
The atomic and electronic structures, the elastic moduli, the vibrational frequencies, and the thermodynamic characteristics of the Ti5Si3 titanium silicide are calculated by the projector augmented wave method within the density functional theory. The Fermi surface is calculated and the electron velocity on all its four sheets is estimated.

Fibrillar Structure and Mechanical Properties of Collagen

Journal of Structural Biology, 1998
Collagen type I is among the most important stress-carrying protein structures in mammals. Despite their importance for the outstanding mechanical properties of this tissue, there is still a lack of understanding of the processes that lead to the specific shape of the stress-strain curve of collagen.

Packing Structure and Mechanical Properties of Granulates

Journal of Engineering Mechanics, 1990
The stiffness tensor relating the stress and strain in the generalized Hooke's law can take various forms depending upon the symmetry of the mechanical properties of the granular material. This material symmetry is expected to be closely related to the packing structure of the granular material.

Mechanical properties and the hierarchical structure of bone

Medical Engineering & Physics, 1998
Detailed descriptions of the structural features of bone abound in the literature; however, the mechanical properties of bone, in particular those at the micro- and nano-structural level, remain poorly understood. This paper surveys the mechanical data that are available, with an emphasis on the relationship between the complex hierarchical structure ...
