In situ growth of nanoparticles through control of non-stoichiometry.
Surfaces decorated with uniformly dispersed catalytically active nanoparticles play a key role in many fields, including renewable energy and catalysis. Typically, these structures are prepared by deposition techniques, but alternatively they could be made by growing the nanoparticles in situ directly from the (porous) backbone support. Here we demonstrate that growing nano-size phases from per...
متن کاملIntermetallic Cerium Compounds with Ordered U3Si2 Type Structure
Z. Naturforsch. 55 b, 155-161 (2000); received November 10, 1999 Intermetallic Cerium Compounds, Crystal Structure New intermetallic cerium compounds Ce2 7iMg (T = Ni, Cu, Pd), CqiTjCd (T Pd, Pt, Au), and CtiTzPb (T = Pt, Au) were prepared by reaction of the elements in sealed tantalum tubes in a high-frequency furnace. Most C e :^ ^ (X = Mg, Cd, Pb) compounds are stable after annealing at abou...
متن کاملNon-Stoichiometry and Calphad Modeling of Frank-Kasper Phases
One of the many singularities of Frank-Kasper phases is their ability to accommodate extremely large composition ranges by atom mixing on the different sites of the crystal structures. This phenomenon will be reviewed in the present paper with special emphasis on the experimental demonstration of this phenomenon, the theoretical calculation of disordered structures and the modeling of these pha...
متن کاملAstrobiological stoichiometry.
Chemical composition affects virtually all aspects of astrobiology, from stellar astrophysics to molecular biology. We present a synopsis of the research results presented at the "Stellar Stoichiometry" Workshop Without Walls hosted at Arizona State University April 11-12, 2013, under the auspices of the NASA Astrobiology Institute. The results focus on the measurement of chemical abundances an...
متن کاملBiological Stoichiometry in Human Cancer
BACKGROUND A growing tumor in the body can be considered a complex ecological and evolutionary system. A new eco-evolutionary hypothesis (the "Growth Rate Hypothesis", GRH) proposes that tumors have elevated phosphorus (P) demands due to increased allocation to P-rich nucleic acids, especially ribosomal RNA, to meet the protein synthesis demands of accelerated proliferation. METHODOLOGY/PRINC...
