Impact of Gap-Graded Soil Geometrical Characteristics on Soil Response to Suffusion

Geotechnics
The phenomenon of fine particle migration through the voids of the granule skeleton under the seepage force is called suffusion. Relative density, original fine particle content, and gap ratio are thought to play vital roles in the suffusion process ...

Direct measurement of shear modulus at low frequencies and small strains

Journal of Physics: Conference Series, 2009
In many applications, one needs to measure elastic moduli of materials at low frequencies and small strains. With most techniques, such as ultrasonic pulse transmission or acoustic resonance, measurements are limited to a few discrete frequencies. These sound speed measurements are also indirect, since they involve density as well as elastic constants.

High‐Resolution and Real‐Time In Situ Generation of Cellular Spheroids by Laser‐Assisted Bioprinting for Guided Microvascularization

Advanced Functional Materials, EarlyView.
Micro‐injection laser‐assisted bioprinting enables ultrafast and precise patterning of small endothelial cell spheroids by injecting a highly concentrated single‐cell suspension into GelMA/ColMA hydrogels. In co‐culture with fibroblasts, controlled pre‐vasculogenic network formation is obtained at microscale resolution.

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

A Modified Rowe Cell with Bender Elements for Small Strain Shear Modulus Measurements

Geotechnical Testing Journal
ABSTRACT The small strain shear modulus (G0) is an important characteristic of geomaterials. Its laboratory measurements are very frequently based on bender element transducers installed in different geotechnical apparatuses. Despite their widespread use, there is room to improve the precision, reproducibility, and robustness of bender ...

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Small strain shear modulus of saturated and unsaturated cohesive soils under anisotropic consolidation

Soils and Foundations
Cohesive soils in nature are created under anisotropic stress and have various stress histories. Embankments generate greater vertical loads underground. Moreover, associated excavation activities can exacerbate the extensional stress state.
