“…Compared to inorganic supports, polymer owns the following advantages and is more suitable for water treatment: low density, big pores, inertia to acids and bases, flexibility, low cost, and high viscosity [15][16][17][18]. Polydopamine coated polyHIPEs (PC-polyHIPEs) are a type of macroporous polymer, which has been confirmed to be an excellent catalyst support and has large 2 Journal of Chemistry attachment to inorganic catalyst particles.…”

Photocatalytic method was investigated to remove water pollutant methylene blue (MB) produced in textile, plastic, and dye industries. PC-polyHIPEs were prepared by light-induced polymerization of dopamine in transparent polyHIPEs which were synthesized by polymerization within high internal phase emulsions. Sr 1− K TiO 3− ( = 0-0.5) nanoparticles were incorporated and adhered to PC-polyHIPEs to form Sr 1− K TiO 3− @PC-polyHIPEs for the first time. The catalysts were characterized by XRD, FTIR, TGA, UV-Vis DRS, and SEM and their photocatalytic properties for MB decomposition were measured over UV-Vis spectrometer. The PC-polyHIPEs were of interconnected porous structure with around 100 m pores and 30 m windows. Sr 1−x K x TiO 3− @PC-polyHIPEs showed excellent MB decomposition activity under either UV or visible light although Sr 1−x K x TiO 3− alone worked only under UV light. When = 0.3, Sr 1−x K x TiO 3− @PC-polyHIPEs showed the highest photocatalytic performance due to the existence of more oxygen vacancies. When the water solution with 50 mg L −1 MB and 1.6 g cat. L −1Sr 0.7 K 0.3 TiO 3− @PC-polyHIPEs was exposed to visible light for 160 min at room temperature, 88.3% of MB was decomposed. After being used for eight cycles, 87.6% activity of fresh Sr 0.7 K 0.3 TiO 3− @PC-polyHIPEs still remained. The influences of salinity, temperature, and catalyst concentration on the catalytic activity were studied. For MB decomposition under visible light, the activation energy of Sr 0.7 K 0.3 TiO 3− @PC-polyHIPEs was calculated to be 12.3 kJ mol −1 and the kinetics analysis revealed that the photocatalysis followed the second-order reaction. These findings demonstrated that Sr 1−x K x TiO 3− @PC-polyHIPEs were an effective candidate for real application in decomposition of MB in water.

“…Different ways of production of palladium nanoparticles production (Redon et al, 2011;Desforges et al, 2005), as well as palladium nanowires and nanorods (Bliznakov et al, 2011) have been investigated. Ohm and Hill (2010) examined thermoelectric behavior of palladium, and Kordas et al (2000) studied Pd thin film deposition on polymers from liquid precursors.…”

ABSTRACT:In order to broaden future application of products based on platinum and palladium a comparative analysis of their high-temperature mechanical properties was performed. Platinum and palladium are of great importance and are widely used in chemical industry, electronics, for making laboratory dishes, to name a few. Mechanical properties of pure metals, such as: tensile strength, creep rate and rupture time were investigated using universal testing machine for tensile testing of materials. Microstructure of samples was investigated by optical microscopy. Based on obtained results it can be concluded that the platinum, compared to palladium, is superior for high-temperature applications. RESUMEN: Estudio de las características mecánicas y estructurales del platino y paladio a altas temperaturas.Se realiza un estudio comparativo de las propiedades mecánicas a alta temperatura del platino y paladio, con el fin de ampliar las aplicaciones de los productos basados en estos metales. El platino y el paladio son de gran importancia y se utilizan ampliamente en la industria química, electrónica y para la fabricación de placas de laboratorio, entre otras aplicaciones. Se estudiaron las siguientes propiedades mecánicas de los metales puros: resistencia a la tracción, velocidad de fluencia y tiempo de rotura bajo condiciones de fluencia. Para esas investigaciones se utilizó una máquina universal de ensayos para realizar los ensayos de tracción. La micro-estructura fue investigada por microscopía óptica. Basándose en los resultados obtenidos, se puede concluir que el platino, en comparación con el paladio, presenta mejores prestaciones para aplicaciones a alta temperatura.
