Synergistic effects in oxygen evolution activity of mixed iridium-ruthenium pyrochlores Rebecca K. Pittkowski, Daniel F. Abbott, Roman Nebel, Spyridon Divanis, Emiliana Fabbri, Ivano E. Castelli, Thomas J. Schmidt, Jan Rossmeisl, Petr Krtil Abstract Pyrochlore oxides (A2B2O7) simultaneously containing iridium and ruthenium in the B-site are promising catalysts for oxygen evolution reaction (OER) in acid media.… Continue reading Synergistic effects in oxygen evolution activity of mixed iridium-ruthenium pyrochlores

Production of bromelain aerosols using spray-freeze-drying technique for pulmonary supplementation M. N. Lavanya, R. Preethi, J. A. Moses, C. Anandharamakrishnan Abstract Spray-freeze-drying (SFD) is a promising technique to produce inhalable dry powder formulations that able to retain the integrity of bioactive compounds. Therefore, in this study bromelain aerosols were developed using SFD by varying core-to-wall… Continue reading Production of bromelain aerosols using spray-freeze-drying technique for pulmonary supplementation

Fabrication and microstructure analysis of continuous C fibers reinforced SiC-Cnfs hybrid composite tubes Shaik Mubina, M. Ilaiyaraja, Asit Kumar Khanra, Bhaskar Prasad Saha Abstract The carbon nanofibers (Cnfs) dispersed SiC-Cnfs composite powder has been produced by spray freeze-granulation technique. SiC-based hybrid composite tubes (BN-Cf/SiC-Cnfs) were fabricated by systematically laying of boron nitride-coated continuous carbon fiber… Continue reading Fabrication and microstructure analysis of continuous C fibers reinforced SiC-Cnfs hybrid composite tubes
