    Notizen: Abstract Much of the recent rapid progress in large-scale genomic sequencing has been driven by the dramatic improvements both in the area of biological protocols and in the availability of improved laboratory instrumentation and automation platforms. We discuss recent developments in the area of bioinstrumentation that are contributing to the current revolution in genetic analysis. Examples of systems for laboratory automation are described together with specific single-purpose instruments. Emphasis is placed on those tools that are contributing significantly to the scale-up of genomic mapping and sequencing efforts. In addition, we present a selection of more advanced measurement techniques and instrumentation developments that are likely to contribute significantly to future advances in sequencing and genome analysis.

    Notizen: The development of new and more sensitive techniques in thermal analyses aids in a more complete understanding of the contributions of individual components in urethane elastomers regarding their mechanical and thermodynamic behavior. The behavior of various segments of the elastomers reported in this work illustrates a clearer interpretation of reasons for changes in mechanical behavior caused by changes in heat capacity, volume and tensile properties; the gross changes previously reported for polyurethane properties as a function of temperature are also confirmed with a more exact definition of their origin.The sub-ambient temperature behavior and response of physical measurements near the melting point of the backbone polyol are largely a function of the so-called “soft block.” The soft block does not contribute to the mechanical properties above the melting point of the polyol unless some urethane segments from the diisocyanate and extender are structured into the soft block, that is, excess diisocyanate and extender are added to build in the “hard” block. The extender and isocyanate influence for both low and high temperature properties is observed by the lack of molecular fit imparted to the backbone polyol as well as some crystallinity in the polymer hard block. The usual Tg transition reported in urethane elastomers corresponds to a first-order transition in the polyester or polyether backbone.

    Notizen: The stress-cracking of polycarbonate by a gaseous or liquid agent results from the diffusion of this agent into the polymer. The low molecular weight polymer fractions and the chain ends within the bulk of the polymer become more ordered during the diffusion and swelling process by their partial solubility in the crazing agent, causing crystallization. The creation of interfaces at areas of order-disorder causes high shearing forces at this boundary and voids within the bulk of the polymer. These voids are then propagated as crazes or cracks at stresses much lower than the tensile strength of the polymer. Therefore, a stress-cracking agent need not diffuse rapidly, but must be an effective environment for swelling and/or crystallization. Data from diffusion, density, thermal and molecular analyses are presented to support this mechanism.

    Notizen: Viton® GLT is a new low-temperature fluoroelastomer with a Tg near -40°C. A study was made on methods of Crosslinking this material while retaining its transparency. Combinations of trimethylolpropane trimethacrylate, TMPTM, and triallyl isocyanurate, Diak® #7, were milled into Viton GLT. After molding, the materials were exposed to electron-irradiation, cross-linking the material. Transparent, tough materials were obtained for compositions containing about 3 percent TMPTM/3 percent Diak #7/3 Mrads, which had an extension of over 100 percent, a tensile strength of over 1000 PSI, excellent clarity, and low surface tack.

    Notizen: Saturated fluorocarbon elastomers are very resistant to chemical reactions, including those of a crosslinking nature. In order to study proper methods of preparing these materials, Viton GLT was mixed with various levels of trimethylol propane trimethacrylate, TMPTM, and triallyl isocyanurate, Diak #7. After molding, the materials were subjected to electron beam irradiation. The glass transition, rubbery modulus, viscoelastic behavior, and equilibrium swelling were used to characterize the materials as a function of crosslinker and irradiation level. In general, the modulus and gel fraction increased with both crosslinker content and irradiation level. Mixtures of both crosslinking monomers produced an unexpected synergism, yielding higher tensile strength, and earlier onset of gelation.
