...pe to metallurgically bond a metallic coating to a metal substrate to demonstrate that barrel materials can be made more resistant to these forces. Compared to mechanical bonding, metallurgical bonding results in far greater strength of the bonds between the atoms of the coating and substrate.

...uilt-in library of nuclear dual-use and high-value metal signatures. The system also identifies varying metals that may have been "co-mingled" to avoid detection. The lightweight system consists of a small sensor probe for scanning and a handheld operating platform custom designed by PNNL to ease use and ...New compound may immobilize AIDS virus, certain radionuclides
...useful chemistry, including bind viruses and large metal atoms such as some radionuclides. Once such compounds bind with an AIDs virus, the virus is no longer capable of entering a cell to damage it. HPAs may also bind with radionuclides called actinides, which removes them from the mixture by phase separa...University of Florida engineers probe 'shape memory' alloy for better prostheses
