Based on the nanostructure of the sea urchin spines, scientists develop fracture-resistant cement.

To find a link between seemingly disparate disordered materials and their behavior under stress, scientists studied an unprecedented range of disordered solids with constituent particles ranging from individual atoms to river rocks. Understanding materials failure on this fundamental level could be key for designing more shatter-resistant glasses or predicting geological phenomena like landslides.

The need for adaptation strategies to reduce the threat of hurricanes to society is of critical importance, as evidenced by the recent damage to coastal regions in the U.S. and the Caribbean this past year. The fact that the number of residential buildings in coastal areas has increased significantly combined with the increasing risks of impacts of due climate change means that the cost of damage to coastal developments are likely to continue to rise.

Wetting is an everyday phenomenon that represents how well liquid spreads on a surface. When water comes into contact with an extremely water-repellent, or ‘superhydrophobic’ surface, droplets bead up and roll off easily. Researchers have developed a measurement technique called Scanning Droplet Adhesion Microscopy (SDAM) to understand and characterize the wetting properties of superhydrophobic materials.

Mathematical models are extremely limited at modeling ballast, the gravel layer located under railway tracks. Researchers have shown that a large part of the energy introduced by a train passing is trapped by the ballast. Their work shows that this trapping phenomenon, which is very dependent on train speed, could cause accelerated ballast degradation in railway tracks.
