It is shown that the recently discovered giant negative magnetoresistance (GMR) effects in ferromagnetic La1−xMxMnO3 (M=Ca,Sr,Ba) are compatible with the existence of high Tc superconductivity in c-axis oriented YBa2Cu3O7/La0.67Ba0.33MnO3 superlattices. From magnetoresistivity measurements we deduce that above Tc the…
The crystallization of amorphous thin films by annealing can sometimes be greatly aided by rapidly bringing the films up to the annealing temperature, so-called rapid thermal annealing (RTA). We have modeled this phenomenon for lead zirconate titanate thin films, incorporating the presence of a long-lived secondary cr…
The complex dielectric functions $\left(2<h\ensuremath{\nu}<4\mathrm{eV}\right)$ of ultrathin crystalline silicon $\left(c\ensuremath{-}\mathrm{Si}\right)$ and amorphous silicon $\left(a\ensuremath{-}\mathrm{S}\mathrm{i}:\mathrm{H}\right)$ films consisting of isolated clusters have been measured at 250 \ifmmode^…
Copper fining trials with ale and lager worts under conditions whereby the pH of wort was artificially manipulated prior to fining, demonstrated that the optimal copper fining rate decreased with increasing values of wort pH. Clarification of acidified worts (pH<4.5) was poor regardless of the rate of copper finings a…
Environmental regulations are requiring the commercial deployment of technologies for the control of nitrogen oxides emissions from stationary sources and are creating opportunities for the development of new technologies. This chapter provides an industrial perspective on the regulatory picture, discusses commerciall…

Detailed adsorption isotherm data are combined with thermodynamic arguments in an effort to determine whether protein adsorption to solids is a reversible or irreversible process. We then examine the dominant driving forces for protein adsorption and present a thermodynamic framework for understanding the protein-adso…
In the wake of damaging earthquakes in both the United States and Japan over the past year, the performance of structures, in addition to traditional life-safety concerns, has become an important issue for designers and owners. Many possible approaches to enhancing the seismic performance of structures have been propo…
We propose a systematic method of analyzing pseudopotential transferability based on linear-response properties of the free atom, including self-consistent chemical hardness and polarizability. Our calculation of hardness extends the approach of Teter\cite{teter} not only by including self-consistency, but also by gen…

Part 2 Aqueous environments: aqueous corrosion fossil fuel combustion power and heat. Part 3 Oil and gas operations: oilfield applications of stainless steel petroleum refining. Part 4 Process…
We present molecular dynamics simulation measurements of the viscosities of the Gay-Berne phenomenological model of liquid crystals in the nematic and isotropic phases. The temperature dependence of the rotational and shear viscosities, including the nonmonotonic behavior of one shear viscosity are in good agreement w…
Food macromolecules play a crucial role in the formulation of a wide range of food products such as beverages, bread, cheese, dressings, desserts, ice-cream, and spreads. This book presents the very latest research in the area and is unique in covering both proteins and polysaccharides in the same volume. Specifically…

We calculate the Raman spectrum of the two-dimensional (2D) spin-1/2 Heisenberg antiferromagnet by exact diagonalization and quantum Monte Carlo techniques on clusters of up to 144 sites and, on a 16-site cluster, by considering the phonon-magnon interaction which leads to random fluctuations of the exchange integral.…
Abstract A series of new, fluorinated poly(imide–amide–sulfone)s has been synthesized by solution polycondensation of aromatic diamines containing sulfone groups with diacid chlorides incorporating both imide and hexafluoroisopropylidene units. These polymers are soluble in polar amidic solvents, and their solutions c…
Porphyrin arrays may act as light-harvesting devices which mimic the photosynthetic capture of light. Until now the construction of a variety of arrays has been restricted by the lack of suitable methodology for porphyrin synthesis. A fully conjugated, aldehyde-appended porphyrin building block has been made and its p…
Abstract A semicrystalline polyamide polymer was processed using a new technique known as mechanical alloying. The material processed by this technique was first introduced into a high‐energy ball mill and ground over long periods of time, resulting in the production of extremely fine powders. These powders were subse…
A value of 2.71 μB for the effective magnetic moment between 100 and 300 K is determined for 1. This magnetic moment supports the assumption of a triplet ground state for 1. The bis(nitroxyl) diradical, which melts only at 180 °C with decomposition, could be characterized by X-ray crystallography. It has a distinctly…
A ferromagnetic exchange interaction that is not influenced by the distortion of the cubane framework of 1 (see picture; only the O atoms of the EtOH and dbm− ligands are shown) and is mediated by the end-on-coordinated μ3-azide bridges has been detected for the first time. Although the unusual [M4(η1-μ3-N3)4] core is…
Eighteen different collagen types have now been identified, at least five of which are found in the extracellular matrix of the heart. The interstitial collagens, types I and III are the most abundant components. Due to their tensile strength and arrangement in a network, surrounding and inter-connecting myocytes and…
