Cementation of Sands Due to Microbiologically-Induced Carbonate Precipitation

Soils and Foundations, 2011
ABSTRACT In this study, microbial precipitation of carbonate was observed using high microbial urease activity, and it was found that the ratio of Mg/Ca affected the types of crystals produced. Without Mg2+, calcite was produced using only CaCl2, while the presence of Mg produced Mg-calcite, magnesite and/or possibly dolomite of round, spherical or ...

A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators

Advanced Science, EarlyView.
This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.

Effects of soluble soybean polysaccharides on solidifying aeolian sand by soybean urease-induced carbonate precipitation

Yantu gongcheng xuebao
The soybean urease-induced carbonate precipitation is potentially valuable for solidifying desert aeolian sand. In order to improve the uniformity and effects of solidification, the soluble soybean polysaccharide (SSPS) is added to the extracted soybean ...

Effect of polymeric capsules on one-dimensional compression and creep of carbonate sand

Carbonate sand, widely distributed in coastal regions, presents challenge due to its high stress-dependent and time-dependent (creep) compressibility. While soil stabilization techniques have traditionally focused on enhancing the strength of carbonate ...

Application of sequence stratigraphic concepts to the cretaceous Urgonian carbonate platform, southeast France [PDF]

, 1992
Carbonate platforms are increasingly being studied using sequence stratigraphic concepts and models borrowed from the study of siliciclastic shelves in passive margin settings. The direct transposition of the stratigraphic model for a siliciclastic shelf

Mechanical properties of a carbonate sand from a dredged hydraulic fill: Discussion

, 2020
The ‘Mechanical properties of a carbonate sand from a dredged hydraulic fill’ (Giretti et al., 2018a) together with its companion paper ‘CPT calibration and analysis for a carbonate sand’ (Giretti et al., 2018b) are valuable because there are limited ...

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

Advanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.
