“…In recent years, with the implementation of construction projects, as an integral part of bridges, the demand for bridge span, relative height of bridge piles, and bridge bearing capacity has continued, and there are more regulations on the construction precision and erection efciency of bridge projects. So we want to reasonably carry out all aspects of the bridge project under new standards and the new mandatory requirements to further strengthen the bridge project mapping work, enhance the bridge mapping work on a variety of resource integration, and actively explore and improve the various aspects of professional technology, which can efectively give full play to mapping in bridge construction to promote the role of the bridge project and enhance the overall quality of the bridge project [19].…”

All along, safety accidents in the field of bridge construction have continued to arise, costing society's development financial and material resources and taking away people’s personal safety, turning into an urgent need for safety managers in the field to solve the subject research. Researchers look forward to continued innovative exploration to find new ways of working safely and using them in the construction industry. On this basis, BIM virtual scenes are introduced to create a universal scene specification dataset in the field of bridge construction and a dataset of unsafe potential hazard characteristics in the field of bridge construction. Nanobots are artificial intelligence systems built to simulate biological nanomachine constructions in life activities and important biological events in life processes. In this paper, BIM virtual scenarios incorporating intelligent nanomaterial robot mapping technology are migrated to bridge engineering safety management. According to the collected construction scene images and BIM (building information model) virtual scenes, build the construction scene dataset, use intelligent robots to obtain construction scenes, and load them into the trained construction on-the-spot neural network modeling to complete the bridge construction scene identification safety discrimination to select more comprehensive and more stringent management solutions as safety management personnel management methods on-the-spot.

“…It is worth noting that experimentalists are beginning to examine the behavior of flexible sheets that are coated with catalytic patches and immersed in fluid-filled microchambers. Recent studies ( 31 ) experimentally validated our earlier prediction ( 20 ) that sheets coated with enzymes (catalase) can undergo directed motion and shape-changing when the appropriate reactant (hydrogen peroxide) is added to the solution. The researchers note that the observed behavior can be rationalized in terms of the solutal buoyancy mechanism (described below), as we had predicted ( 32 ) through our computational modeling of chemically active sheets.…”

Solutal-buoyancy-driven intertwining and rotation of patterned elastic sheets

The intertwining of strands into 3D spirals is ubiquitous in biology, enabling functions from information storage to maintenance of cell structure and directed locomotion. In synthetic systems, entwined fibers can provide superior mechanical properties and act as artificial muscle or structural reinforcements. Unlike structures in nature, the entwinement of synthetic materials typically requires application of an external stimulus, such as mechanical actuation, light, or a magnetic field. Herein, we use computational modeling to design microscale sheets that mimic biology by transducing chemical energy into mechanical action, and thereby self-organize and interlink into 3D spirals, which spontaneously rotate. These flexible sheets are immersed in a fluid-filled microchamber that encompasses an immobilized patch of catalysts on the bottom wall. The sheets themselves can be passive or active (coated with catalyst). Catalytic reactions in the solution generate products that occupy different volumes than the reactants. The resulting density variations exert a force on the fluid (solutal buoyancy force) that causes motion, which in turn drives the interlinking and collective swirling of the sheets. The individual sheets do not rotate; rotation only occurs when the sheets are interlinked. This level of autonomous, coordinated 3D structural organization, intertwining, and rotation is unexpected in synthetic materials systems operating without external controls. Using physical arguments, we identify dimensionless ratios that are useful in scaling these ideas to other systems. These findings are valuable for creating materials that act as “machines”, and directing soft matter to undergo self-sustained, multistep assembly that is governed by intrinsic chemical reactions.

Bio‐inspired approaches in materials science and systems chemistry are yielding a variety of stimuli‐responsive and dynamic materials that are gradually changing our everyday life. However, the ability to chemically program these materials to exhibit macroscopic higher‐order behaviours such as self‐assembly, contractility, swarming, taxis, chemical communication, or predator‐prey dynamics remains an ongoing challenge. While still in its infancy, the successful fabrication of bio‐inspired materials displaying higher‐order behaviours not only will help bridging the gap between living and non‐living matter, but it will also contribute to the development of advanced materials for potential applications ranging from tissue engineering and biotechnology, to soft robotics and regenerative medicine. Our Mini‐Review will systematically discuss the higher‐order behaviours developed thus far in bio‐inspired systems, namely (i) polymer networks (ii) microbots, (iii) protocells, and (iv) prototissues. For each system it will provide key examples and highlight how the emergent behaviour could be chemically programmed.
