Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation

Advanced Materials, EarlyView.
A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.

Rock Mechanics and Rock Engineering

, 2020
This work aims to examine the stress redistribution with evolving seismicity rates using a passive seismic tomographic tool. We compiled a total of 26,000 events from two underground mines and partitioned them into multiple clusters in a temporal ...

Engineering Pluripotent Stem Cells‐Derived Inner Ear Organoids With Enhanced Maturation and Reproducibility by Micro‐Topographical Cues

Advanced Materials, EarlyView.
Micro‐topographical cues applied through temporally controlled microscale confinement improve the reproducibility, spatial organization, and neurosensory‐associated features of pluripotent stem cell‐derived inner ear organoids. Integration with a vascularized organoid platform further enables controlled investigation of vascular‐epithelial interactions

Elastomeric 3D‐Printed Microenvironments Enable Nanonewton Force Measurements in Healthy and Diseased Human Pluripotent Stem Cell‐Derived Neuroepithelial Cells

Advanced Materials, EarlyView.
We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

THE CONSISTENCY CONDITIONS FOR DENSITY LIMITS OF HYPOPLASTIC CONSTITUTIVE LAW

TASK Quarterly, 2000
The so called phase diagram of grain skeletons illustrates the range of possible void ratios between the pressure dependent bounds ei and et. It can be shown that in the framework of the actual hypoplastic model these bounds can be surpassed by ...

Analysis of Cracks Related to Rock Fragmentation

, 1983
In the late 1960’s, fracture mechanics was seldom used in the analysis of rock fragmentation problems. Examplifying rock mechanics textbooks with Jaeger and Cook 1, they they do present Griffith’s theory of fracture and the term fracture mechanics in ...

Interfacial Failure and Self‐Healing in Solid‐State Batteries

Advanced Materials, EarlyView.
Dynamic interfacial self‐healing offers an adaptive route to mitigate coupled mechanical, chemical, and electrochemical degradation in solid‐state batteries. This review connects evolving interfacial failure mechanisms with physical‐flow, chemical‐restoration, stimuli‐responsive, and electric‐field‐assisted repair strategies, highlighting targeted self‐

An innovative method to assess specific charge, drilling and blasting costs considering critical factors of rock mass properties, fragment size and blasthole parameters

Results in Engineering
The specific charge has been given as a function of the blastability index (BI) only in previous research, whereas fragment size is one of the attractive blasting results. The impacts of combination of the important factors such as fragment size, in-situ
