Electrochromic devices can consist of inorganic, organic or polymeric materials in the form of films or liquids. Many cell configurations call for a liquid electrolyte which may be less suitable for an electrochromic window. Solid-state ion injectors (electrolytes) are probably the best for large-scale fabrication.

High thermal conductivity of the ligaments in CENG allowed heat to transfer throughout the alloy rapidly. Good continuity at the interfaces and throughout the CENG structure supplies a "path" for heat transferring [14].As shown in Fig. 3, depending on the bulk density of the CENG, thermal conductivity of the composite along the direction of X
Thermal energy storage provides a workable solution to this challenge. In a concentrating solar power (CSP) system, the sun''s rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use. This enables CSP systems to be flexible, or dispatchable, options for
