This paper presents measurements of the thermal conductivity of paraffins mixtured with zeolites of the type 5A and 13X. Because of their high enthalpy change at the phase transition paraffins are able to store more thermal energy at nearly isothermal conditions than sensible heat materials. The poor thermal conductivity of paraffins is a disadvantage, however. The zeolite provides a structure ...

Normally, 3D printed objects via photopolymerization usually don’t have fully optimized mechanical properties and functions. In this context, the addition of single filler can improve these through access to composite materials. However, inevitably has a negative influence on light penetration inside composites strongly reducing depth cure. Hence, fabrications photo-composites based combination...

Pressure swing adsorption (PSA) technology is used in medical oxygen concentrators for selective of nitrogen under pressure from air to produce oxygen-enriched breathing. The functional material aluminosilicate zeolite like Li-13X, 5A (LTA) with a relatively high Al-content. It selectively adsorbs the into their molecular sieves due strong quadrupolar interaction between adsorbed and electrical...
