Mechanical Metamaterials for Ultra-Low Frequency Vibration Isolation
Background Vibration is one of the main causes of performance degradation of precision instruments, vibration noise, failure of structural parts, and human discomfort. In particular, the human body is most sensitive to vibrations in low frequency range especially for the wounded and newborn babies in transit. Thus, effective low-frequency vibration...

Plasma Treatment to Strengthen Diamonds
Invention SummaryThis invention is applicable to toughening diamonds—that is, to improvements in the wear resistance and/or hardness of natural or synthetic diamond. The treatment is an immersion of the diamond in a low-temperature plasma environment. The plasma cations penetrate into the diamond material. The small ion with an available reactive...
