In this work, we study the modification of hydrogenated diamond films deposited on silicon resulting from its exposure to DBr followed by an annealing above 600 K, using high resolution electron energy loss spectroscopy (HREELS). This procedure results in silicon carbide SiC formation within the diamond film, as evidenced by the observation of a loss peak at 117 meV and its first harmonic at 23...

Membrane gas separation at high temperatures and in the presence of aggressive chemicals, such as H2S, NH3, SOx, NOx hot water vapor, is attracting interest from both a fundamental industrial standpoint. To fully exploit benefits membrane technology, it imperative to develop materials that withstand thermally chemically harsh conditions, well understand principles underpinning transport species...

Drug innovation is characterized by painstaking molecular-level syntheses and modifications as the basic components of research and development. Similarly, natural products are chemically tailored and modified based upon their structural and biological properties. To some extent, the modification of natural products is quite different from de novo structure-based drug discovery. This review des...
