Deoxyoligonucleotide 49-mers containing a central cis-syn, trans-syn-I, (6-4), or Dewar photoproduct of TpT were constructed for use in repair and replication studies by ligation of shorter photoproduct-containing oligonucleotides. A (6-4) product-containing 6-mer was prepared in 3.4% yield by 254 nm irradiation of d(…

The plausibility of the entropic repulsion of electrical double layers acting to stabilize an equilibrium thickness of intergranular glass films in polycrystalline ceramics is explored. Estimates of the screening length, surface potential, and surface charge required to provide a repulsive force sufficiently large to…

Abstract The thermoluminescence dose response of a-Al2O3:C at ultra-low dose levels (100 nGy - 100 µGy) has been measured. It has been shown that computerised glow curve deconvolution (CGCD) can be applied to the glow curve of a-Al2O3:C using two Gaussian peak shape functions, to fit the main peak, superimposed on a l…

Abstract MgB4O7:Dy is usually reported as having one dosimetric peak. Two sets of experimental studies followed by computer analysis of more than 200 glow curves indicate that a combination of at least 11 peaks of first order kinetics is necessary to describe the glow behaviour of MgB4O7:Dy. For a heating rate of 1 oC…

Abstract The effect of solvent on the curing reactions of PMDA/ODA polyamic acids has been investigated using Fourier transform (FT)‐Raman spectroscopy. Films of different thicknesses were cured by: (1) doctor blading 15% solids solutions onto glass slides, (2) removing all but the bound NMP, and (3) removing all the…

It is shown how to calculate the simultaneous effects of crystal fields, itinerant electron polarization, and interionic interactions treated in the mean-field approximation upon the paramagnetic properties of metallic samarium compounds. Expressions are derived for the paramagnetic susceptibility, the hyperfine field…
