Buckle or break [PDF]

open access: yesNature Materials, 2007
The isolation of free-standing graphene sheets seems to contradict common belief about the existence of two-dimensional crystals. Monte Carlo simulations confirm that the sheets may be stabilized by the formation of finite-sized ripples.

Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe

open access: yesAdvanced Functional Materials, EarlyView.
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed

Buckling of elastic filaments by discrete magnetic moments

open access: yes, 2017
We study the buckling of an idealized, semiflexible filament along whose contour magnetic moments are placed. {We give analytic expressions for the critical stiffness of the filament below which it buckles due to the magnetic compression.

Intrinsically Soft Printed Electronics for Digitally Augmented Human Sensing and Vision

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a class of highly functional, multilayer flexible and stretchable circuits capable of digitally augmenting human sensing and vision. Studies in multi‐material soft composite inks yielded a formulation that enables overpass printing, self‐healing, and high‐resolution functionality.

Buckling Analysis of Hetero-Junction Carbon Nanotubes

open access: yesJournal of Mechanical Engineering, 2018
The buckling analysis of carbon nanotubes without and with hetero-junctions is described in this paper. The buckling behaviour was investigated by the finite element method and the carbon nanotubes were modelled as space frame structures.

Reinforced Concrete‐Inspired Multiscale Hierarchical Metamaterial Composite for Synergistic Enhancement Across Thermal, Electromagnetic, and Mechanical Domains

open access: yesAdvanced Functional Materials, EarlyView.
A structurally integrated multiscale hierarchical metamaterial composite (MHMC), inspired by the synergistic architecture of reinforced concrete, achieves simultaneous enhancement of thermal, electromagnetic, and mechanical functionalities. By combining a carbon black‐based mechanical metamaterial with a porosity‐graded cellulose acetate aerogel, this ...
