    A new computational approach to the chemical potential (1990)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A new approach to the computation of chemical potential and free energy is presented. The basic idea is to correct the underestimate obtained by the particle-removal method. Application of the new technique to several different thermodynamic states of the Lennard-Jones (12,6) fluid shows that it is capable of providing reliable estimates of the chemical potential, even at high density where standard methods encounter computational difficulties.

    Investigation of the role of ZnSe films on GaAs using acoustoelectric voltage spectroscopy (1993)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 74 (1993), S. 364-369 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: The electrical properties of the ZnSe/GaAs heterostructure have been investigated using the acoustoelectric voltage spectroscopy technique, and in particular, the role of the high-resistivity ZnSe on the surface passivation of the GaAs substrate has been evaluated. From the transverse acoustoelectric voltage (TAV) spectra, the carrier type and concentration, energy band offsets, and the energy levels of various trap states at the heterostructure interface have been found. The effect of heterostructure epitaxial layer on the surface properties of GaAs has been studied by comparing the normalized changes in TAV amplitude for samples of various epitaxial layers and different thicknesses. From all these measurements, surface recombination velocities (S) have been evaluated. For the pseudomorphic ZnSe films (thickness ≤0.15 μm) on GaAs, a reduction in S has been found. As the thickness of the ZnSe film was increased, the presence of a large number of interface states due to the introduction of misfit dislocations was detected using TAV measurements.

    Monte Carlo calculation of chemical potential for the Stockmayer fluid (1992)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 96 (1992), S. 7867-7868 
    Details
    ISSN: 1089-7690

    Topics: Physics , Chemistry and Pharmacology
    Notes: The chemical potential of the Stockmayer fluid is computed by the canonical ensemble Monte Carlo methods of Widom, Bennett, and Han. Both spherical cutoff and metallic Ewald sum techniques are employed. For the states studied it is found that the Ewald sum provides little improvement over the simpler spherical cutoff, that Bennett's and Han's methods produce essentially the same results, and that for certain states Widom's method is less accurate than Bennett's or Han's. The accuracy of the chemical potential calculated via the three methods was verified with Adams' version of the grand canonical ensemble Monte Carlo method.

    Characterization of ZnSe/GaAs heterostructure using transverse acoustoelectric voltage spectroscopy (1992)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 60 (1992), S. 862-864

    Notes: Transverse acoustoelectric voltage (TAV) spectroscopy has been employed to characterize the interface of high-resistivity ZnSe/GaAs heterostructure. Single- and double-beam TAV spectroscopy have been used to study the interface band and impurity transitions of the heterostructure at room temperature. From the TAV spectrum, a conduction band offset of 0.059 eV was found. The spectral behavior of the TAV waveform for single and double-beam cases was different due to the presence of a large number of surface states at the interface. Additional transitions in ZnSe film were also found in the double-beam case when a bias beam of 2.637 eV was used.

    The molecular structure of the Corynebacterium glutamicum threonine synthase gene (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Molecular microbiology 4 (1990), S. 0 
    Details
    ISSN: 1365-2958
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology , Medicine
    Notes: The minimal region encoding the Corynebacterium glutamicum threonine synthase structural gene and its promoter was mapped by deletion analysis and complementation of the C. glutamicum thrC allele to a 1.6kb region of the recombinant plasmid pFS80. The nucleotide sequence of this and flanking DNA was determined. The transcription and translation start points were identified by S1 mapping analysis and amino-terminal protein sequencing, respectively. The thrC gene encodes a 54481-Dalton polypeptide product. Translation of the thrC mRNA initiates only six nucleotides downstream from transcription. The length of the mRNA transcript is consistent with a single gene transcription unit. The C. glutamicum thrC gene is expressed independently of the other threonine-specific genes hom and thrB.

    On the failure indices of quadratic failure criteria for optimal stacking sequence design of laminated plate (1994)
    Springer
    Applied composite materials 1 (1994), S. 81-85

    ISSN: 1573-4897
    Keywords: Failure index ; Quadratic failure criteria ; Maximum strength ; Optimal stacking sequence

    Notes: Abstract The quadratic failure criterion, which is intended to predict fracture, may be used as an object function for optimal stacking sequence design of laminated plate. However, calculations using a symmetric laminated plate demonstrate that Tsai-Wu theory may give incorrect optimum predictions under uniaxial loading.

    New fluorescent labels for time-resolved detection of biomolecules (1993)
    Springer
    Journal of fluorescence 3 (1993), S. 131-139

    ISSN: 1573-4994
    Keywords: Fluorescence ; multiplex dyes ; photochemistry ; time-resolved spectroscopy

    Topics: Physics
    Notes: Abstract New dyes with characteristic fluorescence lifetimes have been developed for bioanalytical applications. Based upon the concept of “multiplex dyes,” we have designed rhodamine dyes with nearly identical absorption and emission spectral characteristics but different fluorescence lifetimes. Extending this principle to applications with laser diodes, new rhodamines with functional groups for covalent coupling of analytes have been developed. The new labels exhibit absortion and fluorescence beyond 600 nm and have a high quantum efficiency, even in aqueous buffer systems.

    Wear behaviour of aluminium matrix composite materials (1992)

    Notes: Abstract Wear behaviour of aluminium matrix composites is characterized by the dry spindle wear test under various conditions (volume fractions of reinforcements, sliding distances and speeds). Wear resistance of composites is improved due to the presence of reinforcements, but no noticeable improvements are observed in the wear resistance with more than 20% addition of reinforcements. To analyse wear mechanisms, wear surfaces are examined by scanning electron microscopy (SEM). The major wear mechanisms of discontinuous metal matrix composites (MMC)s are strongly dependent on sliding speeds. Dominant mechanism is the adhesive-abrasive wear at low and intermediate sliding speeds, and melt wear at high sliding speeds. Weight loss is linearly increased with the sliding distance. The effect of reinforcements' orientations on wear behaviours is also discussed.
