Summary: The increasing need for outdoor remote sensing using drones and robots and reducing the urban heat island effect has created a demand for highly reflective materials suitable for outdoor use. The development of flexible macroporous silicon monoliths that exhibit high diffuse reflectance has been successful. These materials were prepared using a two-step catalyzed surfactant-free sol-gel process and demonstrated total reflectance of over 97.5% in the 400-1100nm wavelength range. The high reflectance, along with other favorable properties, makes the macroporous silicone monoliths promising for outdoor thermal management applications.

Summary: The main aim of this research was to develop a new low-cost synthesis route for producing ultralight Al2O3 cryogel - fiber composite materials for high temperature insulation. The Al2O3 fibers act as the matrix in these composites instead of the typical reinforcement phase. The synthesis of precursor systems involves sol-gel chemistry, with the same starting materials used for both types of porous Al2O3 systems. The composite systems were characterized using various tests and analysis techniques.

Summary: ZnO hollow microspheres were successfully prepared using a sucrose-derived carbon template-assisted hydrothermal method. The microspheres showed a shell composed of aggregated ZnO nanoparticles and a hollow interior after decomposition of the sucrose-derived carbon core. Both ZnO hollow microspheres and ZnO nanoparticles exhibited excellent photocatalytic activity for rhodamine blue degradation under UV light, with the hollow microspheres showing 10% higher efficiency due to their nanoporous structure, higher surface area, and easy formation of ·OH radicals.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
