Reverse Evolution of Armor Plates in the Threespine Stickleback

Faced with sudden environmental changes, animals must either adapt to novel environments or go extinct. Thus, study of the mechanisms underlying rapid adaptation is crucial not only for the understanding of natural evolutionary processes but also for the understanding of human-induced evolutionary change, which is an increasingly important problem [1-8]. In the present study, we demonstrate tha...

The Heritage of Armor

In the colonial era America’s mounted force consisted of militia mounted on horses to cope with Indian raids or serve with the British in their conflicts with the French in North America. In this early period the continent’s heavily wooded terrain and small population limited the size of mounted units and the extent of their operations. During the Revolutionary War, a need emerged for permanent...

Mechanical Properties and Microstructural Evolution of Ta/TaNx Double Layer Thin Films Deposited by Magnetron Sputtering

Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...
