Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
The preparation and some reaction of F2PSPF2 and F2PC(CF3)2OPF2, and the synthesis of the bis-borane adduct of F2PSSPF2
(Elsevier, 1976)
The potentially bidentate fluorophosphine ligand F2PSPF2 can be prepared in 75% yield from the reaction of F2PBr and [(C4H9)3Sn]2S. On the basis of infrared and Raman spectra, the compound has been assigned a bent confirmation ...
Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Application of resonance Raman spectrometry to the determination of vitamin b12
(Elsevier, 1975-05)
Compartmentalized Photoreactions within Compositionally Anisotropic Janus Microstructures
(WILEY-VCH Verlag, 2011-03-02)
We demonstrate spatially controlled photoreactions within bicompartmental microparticles and microfibers. Selective photoreactions are achieved by anisotropic incorporation of photocrosslinkable poly(vinyl cinnamate) in ...
Λ-Dynamics free energy simulation methods
(Wiley Subscription Services, Inc., A Wiley Company, 2009-08)
Free energy calculations are fundamental to obtaining accurate theoretical estimates of many important biological phenomena including hydration energies, protein-ligand binding affinities and energetics of conformational ...
Expression and regulation of cytochrome P-450I genes (CYP1A1 and CYP1A2) in the rat alimentary tract
(Elsevier, 1992-12-29)
Cytochrome P-450 (P450) enzymes in the mucosa of the alimentary tract may be involved in the activation and/or inactivation of ingested xenobiotics and procarcinogens. Since the multiple P450 enzymes have overlapping ...
Thermodynamics of the monohydrogen difluorides V. Melting thermodynamics of NH4HF2
(Elsevier, 1976-03)
The heat capacity of ammonium hydrogen difluoride was extended from 300 to 450 K by adiabatic calorimetry in order to study the melting phenomenon and provide thermodynamics into the liquid region. The corrected enthalpy ...
Advances in ab initio thermodynamic studies on metal/oxide interfaces
(WILEY-VCH Verlag, 2011-05)
We provide a brief overview of the advances in ab initio thermodynamic studies on metal/oxide interfaces in this paper. Firstly, the development in interface modeling is briefly outlined. Secondly, the fundamentals of ...
Small angle X-ray scattering from coal-derived liquids
(Elsevier, 1982-05)
Small angle X-ray scattering measurements were used to determine the size and shape of asphaltene and preasphaltene micelles in solution. The fraction of the coal-derived liquids forming micelles in solution was as high ...
