However, their specific features such as material incompatibilities, high surface tension and a high solidification point (which is around 240 °C) can create technical issues and systematic failures in hydraulic components and instruments where the molten salt flows.
While heat pipes are a widely used and highly efficient means of spreading heat or transferring it from one location to another, there are some fluid-casing combinations which cannot be used due to material incompatibilities.
However, to realize this vision of bionanoelectronics, researchers need to overcome a number of challenges ranging from materials incompatibility to drastically different operation modes.
Multiple surface treatment technologies are used as an example of: (i) simultaneous selection of materials and processes; (ii) selection of multiple materials each of which fulfills different functions; and (iii) selection of materials with incompatibility issues.
Two key challenges for the molten salt based TES materials are chemical incompatibility and low thermal conductivity.
Incompatibility of materials may result in interface and mechanical failure, with the consequent generation of particulate debris, subsequent osteolysis and implant failure.
Long ago, Cennino Cennini wrote in c. 1400 on the alteration of color, giving examples of inherent vice, problems due to incompatibility of materials, and the effects of methods of preparation of pigments causing color change in works of art.
To this end, following Nye, Kondo, and many others, local deformation incompatibility in the material is adopted as a measure of the density of GNDs.
Although various materials like metal, silicon carbide, graphene, diamond, ceramic, etc., have been used to realize MEMS-based devices, their applicability to realize piezoresistive cantilever sensors is limited due to higher stiffness of the structure, high material cost, fabrication complexity, and incompatibility with batch fabrication.
