How to Find Good Catalysts for Partial Oxidation Reactions

The seminar will discuss the question how good catalysts for (partial) oxidation reactions can be found with the help of descriptors that were identified as activity and selectivity controlling parameters of the particular reaction. As examples the oxidation of hydrogen chloride to chlorine (the Deacon reaction) and its vulcano type behavior within a family of catalysts will be presented. For this reaction the dissociation energy of oxygen was found as the essential scaling parameter.

Caltech announces discovery in fundamental physicsAugust 18, 2015

Scientists recently used the Advanced Photon Source to investigate the existence of instabilities in the arrangement of the electrons in metals as a function of both temperature and pressure, and to pinpoint, for the first time, how those instabilities arise.

New Comprehensive Defect-Crystal-Chemistry Approach to Defect-Fluorite Oxides: (M1-yLny)O2-y/2 (M4+ = Zr, Hf, Ce and Th etc, Ln3+ = lanthanide)

Dr. Akio Nakamura will discuss a comprehensive defect-crystal-chemistry approach as a possible unified generalized Vegard-law (VL) description of non-Vegardianity and non-random defect structure of defect-fluorite oxides as coupled effects of distortion-dilation in macroscopic lattice parameter and microscopic ionic-radius level, respectively.

Insight into obscure transition uncovered by X-raysAugust 12, 2015

The list of potential mechanisms that underlie an unusual metal-insulator transition has been narrowed by a team of scientists using a combination of X-ray techniques. This transition has ramifications for material design for electronics and sensors.

Magneto-transport Driven by Spin-orbital Scattering

Recently, a slew of new effects in layered structures with different magnetic and/or spin orbital properties are under study, which have no analogue in bulk materials or differ subtly from their 3d counterparts. In this work, we theoretically investigate the magneto-transport in two types of magnetic bilayer structures of recent interests by solving the thin film Boltzmann transport equation with generalized Fuchs-Sondheimer boundary conditions in which interfacial spin dependent scattering is incorporated.  

Erdemir receives patent for ultra-fast surface hardening technologyAugust 11, 2015

A newly patented technology by Distinguished Fellow Ali Erdemir and his team at Argonne National Laboratory could greatly extend the lifetime of mechanical parts. The team designed a device for ultra-fast boriding, which compared to conventional boriding techniques saves time, money and energy, and even alleviates environmental concerns.
