Advanced Microbial Mineralization Technology and Multi-Scenario Applications in Geotechnical Engineering

Dear Colleagues,

Under the new era of low-carbon environmental sustainability and strong cross-scale engineering requirements, microbial civil engineering technologies represented by microbially induced carbonate precipitation (MICP) have seen significant advances. Rapid progress has been made in research on microbial mineralization and its integration with other low-carbon technologies. Beyond its direct applications in concrete self-healing and permeability reduction, MICP has been extensively adopted in geotechnical engineering and porous media materials. It is now widely utilized for concrete remediation, loose soil solidification, permeability reduction in highly permeable soils, sand layer liquefaction resistance, pollutant immobilization, carbon sequestration and the conservation of earthen heritage sites. In recent years, this technology has continued to evolve.

This Special Issue is grounded in the biomineralization principles of MICP and aims to present recent advances in underground engineering, foundation treatment, contaminated sites, cultural heritage conservation, geological hazard mitigation and natural ecological restoration, across multiple breadths, scales and scenarios. Topics of interest include, but are not limited to, the following:

• Mechanisms of multi-strain microbial mineralization and environmental adaptability analysis
• Multi-field coupling mechanisms and regulation strategies in microbial mineralization
• Microscale and mesoscale characterization methods and imaging techniques for microbial mineralization
• Mathematical modeling and numerical simulation approaches for microbial mineralization
• Big data analytics and multi-scenario intelligent modeling of microbial mineralization
• Mechanisms and technologies for incorporating nanomaterials and fibers in microbial mineralization
• Encapsulation technologies for microbial mineralization and crack self-healing
• Mechanisms influencing microbial mineralization under extreme environments and anti-mineralization degradation processes
• Case studies and field applications of microbial geotechnical engineering

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
