The major part of O-rings is caoutchouc, which is not resistant to several solvents, acids, oils, or bases, and this can cause structural deviations in sealing. The present work shows a compatibility study of O-rings to solvents at laboratory scale. The ...

The ecosystem of the abyss is one of the fields that humans hardly know. The ultra-high hydrostatic pressure makes it very difficult to obtain abyssal organisms. Samples are often severely broken during recovery due to changes in environmental pressure, ...
