  • distributed modular temperature strain sensor based on optical fiber embedded in laminated composites
    Composites Part B-engineering, 2019
    Co-Authors: Marcelo A Soto
    Abstract:

    Abstract A smart structure based on carbon fiber reinforced polymer (CFRP) embedding optical fibers is proposed for distributed sensing in structural health monitoring. The proposed CFRP package provides Mechanical Protection to the optical fiber, enables temperature-strain discrimination, and also facilitates the sensor's installation to secure reliable measurements. Experimental results verify a linear strain sensor response with temperature compensation, agreeing well with the response of strain gauges and the expected theoretical behavior. The smart structure can be used by gluing it on the surface of the monitored structure or by embedding it as one of the layers used during manufacturing big composite structures.

  • Silk cocoon (Bombyx mori): multi-layer structure and Mechanical properties.
    Acta Biomaterialia, 2012
    Co-Authors: Fujia Chen, David Porter, Fritz Vollrath
    Abstract:

    Bombyx mori cocoon is a natural composite made of silk fibre with a distinctive multi-layer structure that provides Mechanical Protection for its biological functions. Here we investigate the components, structure and Mechanical properties of cocoon layers, and quantify the contributions of the multi-layer structure to the Mechanical properties of cocoon. A better understanding of the multi-layer mechanism of a natural composite could help the further design of biomimetic multiscale artificial materials.

  • Brief communication - Cardiac general Cardiopulmonary bypass line sternal wrapping: technical tips
    2020
    Co-Authors: Carlo Aratari, Alexander Manche, Filippo Capestro, Lucia Torracca
    Abstract:

    a Abstract Cardiopulmonary bypass line sternal wrapping (SW) is a new approach to sternal care which avoids bone wax and offers Mechanical Protection and a shield from bacterial contamination, with beneficial effects on sternal healing. Since its introduction in February 2008, the technique has undergone some developments: it is possible to harvest internal thoracic arteries with SW in place and its haemostatic properties have improved. 2010 Published by European Association for Cardio-Thoracic Surgery.

  • SHORT COMMUNICATION A Novel Mechanism by which Silica Defends Grasses Against Herbivory
    2020
    Co-Authors: J. W. Hunt, Andrew P. Dean, Rachel E. Webster, Giles N. Johnson, A. R. Ennos
    Abstract:

    †Background and Aims Previous studies have shown that silica in grass leaves defends them against small herbivores, which avoid high-silica grasses and digest them less efficiently. This study tested the idea that silica can reduce digestibility by preventing the Mechanical breakdown of chlorenchyma cells. †Methods Both the percentage of total chlorophyll liberated from high- and low-silica grass leaves by Mechanical grinding and the chlorophyll content of locust faeces were measured. †Key Results High-silica grasses released less chlorophyll after grinding and retained more after passing through the gut of locusts, showing that silica levels correlated with increased Mechanical Protection. †Conclusions These results suggest that silica may defend grasses at least in part by reducing Mechanical breakdown of the leaf, and that Mechanical Protection of resources in chlorenchyma cells is a novel and potentially important mechanism by which silica protects grasses.
