Small-strain triaxial tests and constitutive modeling of Shanghai soft clays

open access: yesYantu gongcheng xuebao, 2018
In order to reduces the influence of the existing buildings in the surrounding area, the surrounding soil of the new project usually requires the control of the small strain state (0.001%~0.1%).

Strain induced mobility modulation in single-layer MoS$_{2}$ [PDF]

open access: yes, 2015
In this paper the effect of biaxial and uniaxial strain on the mobility of single-layer MoS$_{2}$ for temperatures T $>$ 100 K is investigated. Scattering from intrinsic phonon modes, remote phonon and charged impurities are considered along with static ...

Application of a Pyruvate-Producing Escherichia coli Strain LAFCPCPt-accBC-aceE: A Case Study for d-Lactate Production

open access: yesFermentation, 2020
Pyruvate, a potential precursor of various chemicals, is one of the fundamental chemicals produced by the fermentation process. We previously reported a pyruvate-producing Escherichia coli strain LAFCPCPt-accBC-aceE (PYR) that has the potential to be ...

Orientation-dependent extreme shear strain in single-crystalline silicon - from elasticity to fracture

open access: yesMaterials & Design, 2023
Measuring strain accurately at small length scales poses a significant challenge, making it difficult to obtain precise elastic properties of small materials. This becomes particularly pronounced for test geometries beyond micro-pillars and for materials

Experimental study on HSS model parameters for marine soft soils in Yangjiang, Guangdong Province

open access: yesYantu gongcheng xuebao, 2021
The offshore wind turbine structure has strict control criteria of the tilt and the resonant frequency of the foundation, while the small strain stiffness of the marine soils plays an important role in these properties.

Stiffness of a biocemented sand at small strains

open access: yesEuropean Journal of Environmental and Civil Engineering, 2016
This paper presents the triaxial testing results of a study in which biocementation processes were employed to observe the behaviour at small strains of sand matrix. Biocementation was achieved using the microorganism Sporosarcina pasteurii, an aerobic bacteria growth in natural soil deposits.

Polypyrrole/Agarose Hydrogel-Based Bladder Volume Sensor with a Resistor Ladder Structure

open access: yesSensors, 2018
Chronic monitoring of bladder activity and urine volume is essential for patients suffering from urinary dysfunctions. However, due to the anatomy and dynamics of the bladder, chronic and precise monitoring of bladder activity remains a challenge.
