Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Transparent Deformable Thin Film Electric Heater for Stable and Accurate Control of High Temperatures

Advanced Functional Materials, EarlyView.
Au/GaOx‐based transparent heaters combine high optical transmittance and low sheet resistance with exceptional thermal stability up to 521°C for over 6 h. The interfacial GaOx layer suppresses dewetting of Au and enhances adhesion, ensuring mechanical robustness during deformation and reliability for real‐world applications including grilling ...

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

Advanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

Cohesive crack analysis of size effect

Engineering Fracture Mechanics, 2009
Abstract This paper deals with the analysis of size effect in concrete. An extensive campaign of accurate numerical simulations, based on the cohesive crack model, is performed to compute the size effect curves (CSEC) for typical test configurations.

Ultrasonic sizing of short surface cracks

Ultrasonics, 2007
This paper presents a method for ultrasonic sizing of surface cracks based on time domain and frequency domain Rayleigh wave near-field analysis. The procedure allows for the entire range of ratio of crack depth to Rayleigh wavelength a/lambda to be covered with one single measurement. In the time domain the time-of-flight method was extended to cracks

The influence of crack size on the fracture behaviour of short cracks

International Journal of Fracture, 1990
Crack size effects are investigated by applying local fracture criteria at a specific distance ahead of a crack tip, related to the material’s microstructure. For sufficiently long cracks, the criteria are applied at points within the singularity-dominated region and then failure corresponds to the attainment of a critical intensity of the singularity ...

The effect of crack closure on the reliability of NDT predictions of crack size

NDT & E International, 1987
Abstract The aim of this work is to investigate the effect of crack closure on the reliability of NDT predictions of crack size. Tests are performed on mild steel plate specimens each possessing a fatigue crack. The amount of crack opening or closure is controlled using a specially built four-point bending rig.

Punching shear of slabs: crack size and size effects

Magazine of Concrete Research, 2002
Fictitious crack model assumptions and equilibrium equations were used to develop a numerical model in order to predict the punching load and the deformations of reinforced concrete slabs. Concrete strength, aggregate type, reinforcement ratio as well as the fracture strength properties were taken into account in developing the new model.

Detecting Type and Size of Road Crack with the Smartphone

22017 IEEE International Conference on Computational Science and Engineering (CSE) and IEEE International Conference on Embedded and Ubiquitous Computing (EUC), 2017
Detecting crack type and crack size is crucial for road maintenance and management. Mobile crowd sensing is a new way to collect the information of cracks on roads. We propose a system named CrackDetector to detect cracks and estimate their types and size with smart phone in this paper.
