Crystal plasticity finite element simulations of cast α-uranium [PDF]

open access: yes, 2019
α-uranium, the stable phase of uranium up to 670◦C, has a base-centred orthorombic crystal structure. This crystal structure gives rise to elastic and thermal anisotropy, meaning α-uranium exhibits complex deformation and fracture behaviour ...

Crack‐Growing Interlayer Design for Deep Crack Propagation and Ultrahigh Sensitivity Strain Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A crack‐growing semi‐cured polyimide interlayer enabling deep cracks for ultrahigh sensitivity in low‐strain regimes is presented. The sensor achieves a gauge factor of 100 000 at 2% strain and detects subtle deformations such as nasal breathing, highlighting potential for minimally obstructive biomedical and micromechanical sensing applications ...

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3

open access: yesAdvanced Functional Materials, EarlyView.
Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,

Formation and deformation mechanisms of gradient structures: The role of strain hardening

open access: yesMaterials & Design
Gradient structures (GS) have emerged as a focal point due to their capability to overcome the performance limitations of homogeneous materials. In this study, GS was prepared using the cyclic torsion method for low-carbon (LC) and twinning-induced ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
