Bacteria-based repair and self-healing of concrete

Durability problems in concrete can often be linked to a high permeability, which is either caused by a high matrix permeability or the presence of cracks. Therefore, treatments that reduce the permeability of the matrix, or that close the crack from ingress of aggressive agents carried by water or air, would substantially enhance the service life of a concrete structure. Several chemical products are currently in use for consolidation and crack repair, but a new technique that has been the focus of much research efforts over the last decade is the bacteria-based calcium carbonate precipitation. This technique is now slowly making its way towards practical applications. The principles of the technique, the important influential parameters and the recent advances related to its use for consolidation, surface protection, external crack repair, and self-healing of cracks in concrete are discussed in this article. Also the wider applicability for mechanical strengthening and consolidation of natural stone and soils is shortly treated.

3D Printing: current use in facial plastic and reconstructive surgery.

Purpose of review: To review the use of three-dimensional (3D) printing in facial plastic and reconstructive surgery, with a focus on current uses in surgical training, surgical planning, clinical outcomes, and biomedical research. To evaluate the limitations and future implications of 3D printing in facial plastic and reconstructive surgery. Recent findings: Studies reviewed demonstrated 3D printing applications in surgical planning including accurate anatomic biomodels, surgical cutting guides in reconstruction, and patient-specific implants fabrication. 3D printing technology also offers access to well tolerated, reproducible, and high-fidelity/patient-specific models for surgical training. Emerging research in 3D biomaterial printing have led to the development of biocompatible scaffolds with potential for tissue regeneration in reconstruction cases involving significant tissue absence or loss. Major limitations of utilizing 3D printing technology include time and cost, which may be offset by decreased operating times and collaboration between departments to diffuse in-house printing costs Summary: The current state of the literature shows promising results, but has not yet been validated by large studies or randomized controlled trials. Ultimately, further research and advancements in 3D printing technology should be supported as there is potential to improve resident training, patient care, and surgical outcomes.
