IF A 10-FOLD INCREASE in the resolving power of an analytical tool grabs the attention of scientists, imagine the response to a 10 billion-fold improvement. That is the magnitude of the time-resolution enhancement in electron energy loss spectroscopy (EELS) that researchers at California Institute of Technology report…
We study the kinetics of the liquid-to-crystal transformation and of gel formation in colloidal suspensions of oppositely charged particles. We analyse, by means of both computer simulations and experiments, the evolution of a fluid quenched to a state point of the phase diagram where the most stable state is either a…
This Master Thesis is dedicated to photonic crystal, in particular to macroporous silicon. We introduce the concepts of crystallography, and symmetry, and important associated tools to its study, the Reciprocal lattice, and the Brillouin Zone. We also give a brief explanation of anodic macropore formation in silicon;…
This research was to study the development of Indian women dresses of Punjabi style made by weaving cotton fabric from the north-eastern part of Thailand. The sampling group was 250 Indian women who live in Bangkok selected by Quota Sampling and analyzed by SPSS.
Thermogravimetry experiments and thermal analysis kinetics are used to analyze the effects of magnesium hydroxide on asphalt pyrolysis characteristics. The pyrolysis models are developed based on experiments to evaluate the flame-retarded mechanism of magnesium hydroxide to asphalt. The results indicate that asphalt p…
Photoconduction behaviour of 75 MeV oxygen ion-irradiated (fluence: 1.8×1013 ions/cm2) kapton-H polyimide film in the visible region has been investigated for different electrode materials at various operating temperatures ranging 40–250 °C and at different electric fields (40–400 kV/cm). A photoinduced exciton format…
Measurement and theory of the two-terminal conductance of monolayer and bilayer graphene in the quantum Hall regime are compared. We examine features of conductance as a function of gate voltage that allow monolayer, bilayer, and gapped samples to be distinguished. In particular, we analyze the distortions of quantum…
We have investigated the magneto-optical properties of 1% Cr-doped CdMnTe, known to be a diluted magnetic semiconductor (DMS), grown by using the vertical Bridgman method. From the Faraday rotation measurements, the Verdet constant for Cd 0.62Mn 0.37Cr 0.01Te was -0.93 deg/cm • G at 625 nm (T = 10 K), which is in a di…
The cover picture shows the selective detection of phosphotyrosine by using a terbium(III) complex. This strategy is a combination of Tyr-targeted energy transfer and phosphate-directed interaction, as indicated in the upper part of the picture. The phosphorylation of Tyr can easily be detected by its luminescence, wh…
The influence of high-temperature annealing on absorption spectra of nominally pure and impure MgO crystals irradiated in a nuclear reactor has been investigated. In nominally pure crystals, as a whole, the accumulation of defect aggregates of non-monotonous character takes place during the whole cycle of the action o…
When the strain tensor, the scalar damage quantity and the Laplacian thereof serve as the state variables of Helmholtz free energy, the general expressions of elasticity-gradient damage constitutive equations are derived directly from the basic law of irreversible thermodynamics by constitutive functional expansion me…
In this paper we generalize some of our results from, `A note on Farey fractions with odd denominators' to subsets of Farey fractions consisting of fractions with denominators not divisible by a given prime. We also investigate the joint distribution of numerators of differences of h-tuples of consecutive fractions in…
In this contribution, on the basis of micropolar (Cosserat) continua approach, a constitutive model for simulation of granular material (e.g. sand) response in the elastoplastic range has been presented. Numerical analyses on strain localization in single and two phase materials are carried out in the last part of thi…

A procedure is proposed for computing the virial stresses in an armchair Single-Walled Carbon NanoTube (SWCNT) under uniaxial tension. Computation is based on molecular dynamics simulations and the virial stress theorem. The proposed approach is compared with other methods used in the literature for calculating the st…
Classification of proteins based on their structure provides a valuable resource for studying protein structure, function and evolutionary relationships. With the rapidly increasing number of known protein structures, manual and semi-automatic classification is becoming ever more difficult and prohibitively slow. Ther…
We perform a combined experimental and theoretical study of tetramethyltetraselenafulvalene (TMTSF) single-crystal field-effect transistors, whose electrical characteristics exhibit clear signatures of the intrinsic transport properties of the material. We introduce a simple, well-defined model based on physical param…

The Defense Waste Processing Facility (DWPF) initiated processing of Sludge Batch 4 (SB4) in May 2007.SB4 was the first DWPF sludge batch to contain significant quantities of HM or high Al sludge.Initial testing with SB4 simulants showed potential negative impacts to DWPF processing; therefore, Savannah River National…
