This book addresses the very latest research and development issues in high voltage technology and is intended as a reference source for researchers and students in the field, specifically covering developments throughout the last decade.
Nature and properties of sediment.- Chemical composition of freshwater.- Sediment and the phosphate cycle.- Sediment and the phosphate cycle.- Sediment and the nitrogen cycle.- Methodological aspects.
This new edition of the hugely successful Quantitative Financial Economics has been revised and updated to reflect the most recent theoretical and econometric/empirical advances in the financial markets. It provides an introduction to models of economic behaviour in financial markets, focusing on discrete time series…
As a result of its versatility and simplicity, the chemical precipitation technique remains one of the most widely used methods for the preparation of finely dispersed matter with well-controlled properties. This review deals with the synthesis of highly uniform metallic particles of simple and complex natures by prec…
Crystalline solids undergo large changes in their structure and properties as they transform between different polymorphs in response to the pressure and the temperature. It now appears that analogous density- or entropy-driven phase transitions also occur within the liquid state: these represent a new type of general…
The morphology of attack at and around the intermetallic compounds (IMC) present on bare AA 2024-T3 was studied in situ using confocal laser scanning microscopy. Exposures were conducted in at pH 3, 6, and 10 as well as near-neutral 0.5 M NaCl. The types of attack observed could be categorized as matrix and IMC pittin…
Treatment of bacteria with silver yields intense and highly specific surface-enhanced Raman spectroscopy (SERS) spectra from various cellular chemical components located in the vicinity of the silver colloids. In particular, we demonstrate an extreme sensitivity to flavin components associated with the cell envelope a…
Nanotubes prepared by the self-assembly of D-Phe-D-Phe molecules are investigated by electron microscopy and Monte Carlo simulations; the nanotubes appear to be porous and are capable of forming novel peptide-nanotube platinum-nanoparticle composites.
A suite of 18 zircon gemstones from placers in the Highland/Southwestern Complex, Sri Lanka, were subjected to a comprehensive study of their radiation damages and ages. The investigation included X-ray diffraction, Raman and PL spectroscopy, electron microprobe, PIXE and HRTEM analysis, as well as (U-Th)/He and SHRIM…
Here we report small molecule hydrogels formed by the combination of two N-(fluorenyl-methoxycarbonyl) amino acids, which belong to a novel class of antiinflammatory agents.
Guar gum was tested as corrosion inhibitor for carbon steel in 1 M H 2 SO 4 solution using weight loss and Tafel polarization techniques. The results showed that the inhibition efficiency increases with the increasing of the guar gum concentration, which act as an inhibitor of the mixed type. The inhibition action of…
Carbon nanotubes (CNTs) are attracting much interest as fibrous materials for reinforcing metal matrix composites due to their remarkable properties such as very high strength, elastic modulus, flexibility and high aspect ratios. However, due to the intricate entanglements of long and fine CNTs and resulting aggregati…
Here we report a simple approach to develop assays based on the hydrogelation of small molecules for quick detecting inhibitors of enzymes.
Polyoxygenates such as polyesters and polycarbonates derived from readily renewable resources, e.g. lactide from corn and carbon dioxide, are attractive as environmentally friendly (green) alternatives to polymers derived from fossil fuels, and will play an increasing role in the market place as we move from petrochem…
The review covers materials currently available or which appear to be in serious development, with emphasis on electrical laminates and encapsulation, and brief coverage of other applications. The dominant technology for FR-4 printed wiring boards uses tetrabromobisphenol-A reacted into the epoxy resin. Nonhalogen sys…
Nanofibrous poly(L-lactic acid) (PLLA) scaffolds were fabricated by an electrospinning technique and characterized by scanning electron microscopy, mercury porosimeter, atomic force microscopy and contact-angle test. The produced PLLA fibers with diameters ranging from 150 to 350 nm were randomly orientated with inter…
Multiscale simulation approaches are needed in order to address scientific and technological questions in the rapidly developing field of carbon nanotube electronics. In this paper, we describe an effort underway to develop a comprehensive capability for multiscale simulation of carbon nanotube electronics. We focus i…
This review article gives an overview of the new and quickly developing field of shape memory alloy (SMA) actuators in smart structures. The focus is on the aspects of modeling and simulation of such structures, a task that goes beyond classical modeling approaches as it has to combine constitutive modeling with struc…
Structure–activity correlations of solid catalysts and time-resolved studies generally require that the structure within a solid catalyst is probed simultaneously and at the same location where the catalysis and the structural changes occur. These requirements lead to a compromise between the spectroscopic arrangement…
The La10 − x(SiO4)6O3 − 1.5x (9.33 ≤ 10 − x ≤ 9.73) apatite series has been prepared and hexagonal single phases were obtained in a narrow compositional range (9.33 ≤ 10 − x ≤ 9.60). The room temperature crystal structure of La9.55(SiO4)6O2.32 has been determined from joint Rietveld refinement of neutron and laborator…
