The journal publishes a wide range of research and application papers which describe laboratory and numerical investigations or report on full scale projects.

Construction and Building Materials also publishes detailed case johnson fine and review articles, as well as short communications johnson fine discussions. A new example out of Imperial College London applies this type of thinking to tiny 3D building blocks that can repair their own damage. One area of living material research where we are seeing quite a bit of activity concerns concrete, with studies demonstrating how bacteria can be embedded in the material and respond to water damage by johnson fine and producing limestone or special glues that fill cracks.

Another initiative has even seen the creation of a "biological apartment," where samples of living materials will be swapped in and out fortine see how they perform. Ultimately, we want to increase the lifetime of a product, prevent failures of systems before the problem is visible to the naked eye and have the material think for itself.

This would build on earlier work from the group on similar materials that could detect changes around them, by developing versions that could take on a more active role and serve as versatile building blocks for a range of purposes.

These 3D spheroids can then be arranged into shapes and patterns just like building blocks, and the team put their self-repairing abilities to the test in a naturally occurring structural material called bacterial cellulose.

Bacterial cellulose is a scaffold-like material addiction sex is synthesized by some bacteria and has wide-ranging potential in a number of industries, finding use in high-strength paper, filters in speakers and in medical care as wound dressing. The scientists punched holes in a thick layer of bacterial cellulose and then planted their spheroids in the voids.

After three days of incubation, the spheroids johnson fine the damage and restored the johnson fine and appearance johnson fine the original material. This could lead to windshields that fix their own cracks, aircrafts that repair their own fuselages or potholes that seal themselves in the road. Such a future is a long ways off, but the johnson fine are working toward it by fusing their spheroids with materials like sponges, wood and cotton.

The more short-term applications for the technology, however, lie in the medical field. We are currently working on hosting other living organisms within the spheroids that can live together with the cellulose-producing bacteria," says first author Dr Joaquin Caro-Astorga.
