Keeping an Eye on the Health of Structures

Scientists at Tokyo Tech used synthetic-aperture radar data from four different satellites, combined with statistical methods, to determine the structural deformation patterns of the largest bridge in Iran. The importance of roads and bridges for humans both during ancient and contemporary times is clearly evident. The structural health and integrity of such large structures are,

Dynamic Multivariate Accelerated Corrosion Test Protocol

The objective of this effort was to develop a comprehensive test protocol to accurately predict all aspects of the performance lifetime of Department of Defense (DoD) coatings and alloys. This test protocol was to be comprised of a test methodology which would include the development of a test chamber, modified to include the synergistic effects

Oyster Shells Inspire New Method to Make Superstrong, Flexible Polymers

Researchers at Columbia Engineering have demonstrated for the first time a new technique that takes its inspiration from the nacre of oyster shells, a composite material that has extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a polymer initially well mixed with nanoparticles, the team was able to control
