Article Abstract
The demand for deformable optoelectronic devices that are bendable, stretchable, and foldable has significantly increased. Accordingly, recent research has focused on ensuring the flexibility and stretchability of devices under various deformation modes, making the evaluation and enhancement of the mechanical reliability crucial. Here, we review strategies to improve the flexibility and stretchability of deformable optoelectronic devices, including intrinsic approaches to increasing the elastic deformation limit of materials and extrinsic structural design strategies at the device level. We introduce recent advances in the mechanical reliability of these devices in different deformation modes. Furthermore, we discuss mechanical testing methods for enhancing mechanical reliability, including conventional bulk-scale mechanical testing, nanomechanical tests for constituent thin-layer materials, and computational simulation tools for analysis and prediction.

Rapid identification and accurate diagnosis are critical for individuals with acute leukemia (AL). Here, we propose a combined deep learning and surface-enhanced Raman scattering (DL-SERS) classification strategy to achieve rapid and sensitive identification of AL with various subtypes and genetic abnormalities. More than 390 of cerebrospinal fluid (CSF) samples are collected as targets, encompassing healthy control, AL patients, and individuals with other diseases.

AlN is a core material widely used as a substrate and heat sink in various electronic and optoelectronic devices. Introducing luminescent properties into intrinsic AIN opens new opportunities for next-generation intelligent sensors, self-powered displays, and wearable electronics. In this study, the first evidence is presented of AlN crystals exhibiting satisfactory mechanoluminescence (ML), photoluminescence (PL), and afterglow performance, demonstrating their potential as novel multifunctional optical sensors.

Hepatic encephalopathy (HE) is a neurological condition that occurs as a complication of liver dysfunction that involves sensorimotor symptoms in addition to cognitive and behavioral changes, particularly in cases of severe liver disease or cirrhosis. Previous studies have reported spatially distributed structural and functional abnormalities related to HE, but the exact relationship between the structural and functional alterations with respect to disease progression remains unclear. In this study, we performed surface-based cortical thickness comparisons and functional connectivity (FC) analyses between three cross-sectional groups: healthy controls (HC, = 51), patients with minimal hepatic encephalopathy (MHE, = 50), patients with overt hepatic encephalopathy (OHE, = 51).

Silicon carbide nanowires (SiC NWs) combine the benefits of bulk SiC materials with the properties of low-dimensional nanomaterials. They are known for their excellent mechanical strength and durability, which are critical for their potential applications in high-stress environments and micro-nano functional systems. Here, the mechanical properties and deformation mechanisms of 2H-SiC NWs with rare defects in the [0001] orientation are reported.
