wax below the trough of an oval tubular SS. The water yield, energy efficiency, and CPL were 6.78 L/m2, 61.59 %, and 0.017 $/L, respectively. The water yield and efficiency of the SS with paraffin wax were enhanced by 32.42 % and 41.26 %, respectively, compared with wax-free SS. ...
(f) High-resolution image showing a graphite-like nanotube that encapsulates the catalyst. The power spectrum inset shows only graphite reflections. Following the microwave-assisted catalytic decomposition of paraffin wax, ruthenium catalyst particles of larger sizes with an average diameter of some tens...
The presence of carbon monofilament can create a continuous path of heat transfer through polymeric systems and enhances thermal conductivity [24], [25], [26]. This network can also prevent the shrinkage of aerogel during its preparation [26]. In addition, zinc borate improves the thermal ...
