	abstract = {The measurement of interproton nuclear Overhauser enhancements (NOEs) and dihedral angle restraints of aromatic amino acids is a critical step towards determining the structure of a protein. The complete assignment of the resonances from aromatic rings and the subsequent resolution and identification of their associated NOEs, however, can be a difficult task. Shown here is a strategy for assigning the H-1,C-13, and N-15 signals from the aromatic side chains of histidine, tryptophan, tyrosine, and phenylalanine using a suite of homo- and hetero-nuclear scalar and NOE correlation experiments, as well as selective deuterium isotope labelling. In addition, a comparison of NOE information obtained from homonuclear NOE spectroscopy (NOESY) and C-13-edited NOESY - heteronuclear single quantum correlation experiments indicates that high-resolution homonuclear two-dimensional NOESY spectra of selectively deuterated proteins are invaluable for obtaining distance restraints to the aromatic residues.},

	abstract = {The framework structure of As-synthesized ALPO(4)-14 has been investigated with a combination of different one-dimensional Al-27 and P-31 solid State NMR techniques and Al-27/P-31 double resonance methods. The results are found to be fully consistent with the assumed structural model. Al-27 MAS and DOR experiments at three different magnetic field strengths together with simulations show the presence of two tetrahedral sites, one pentacoordinated and one octahedral aluminum site. The Al-27 quadrupolar coupling constants and the P-31 isotropic chemical shifts of the tetrahedral sites correlate well with tetrahedral shear-strain parameters and mean P-O-Al bond angles, respectively. These correlations allow one to assign all of the NMR resonances to specific T-sites in the proposed framework structure. The assignments are then further confirmed by the application of three different two-dimensional heteronuclear correlation methods (i.e., Al-27 {\textendash}> P-31 TEDOR, CP, and INEPT) which reveal the connectivities between AlOx and PO4 polyhedra. The two-dimensional INEPT experiment is applied here for the first time in the solid state. (C) 1997 Published by Elsevier Science B.V.},

The approach makes use of the recently developed quantitative-J correlation spectroscopy [Bar, A. et al.

An application of this method to a uniformly N-15,C-13-labeled cellulose-binding domain is presented. When used in combination with a NOESY-HSQC experiment, the predominant chi(2) dihedral angles of two asparagine side chains in this protein can also be defined.},

Coherence transfer from quadrupolar Al-27 (I = 5/2) to Si-29 (I = 1/2) nuclei through cross polarization and transferred-echo double-resonance (TEDOR) experiments is. observed, and an experimental investigation of the parameters controlling the efficiency of both experiments is presented. Rotational-echo double-resonance (REDOR) and dipolar-dephasing difference experiments are also demonstrated. These experiments utilize the heteronuclear dipolar couplings, whose magnitudes are proportional to the inverse third power of the internuclear distance and are therefore extremely sensitive to the separation of the coupled spins. In addition, we demonstrate that for these dipolar-based experiments, there is a relative enhancement of a given resonance which is approximately linear with the number of aluminum atoms in the neighboring tetrahedral sites. Two-dimensional extensions of the cross-polarization and TEDOR experiments are also possible and will be of use for complex mixtures or where several resonances are observable in the one-dimensional spectra of the two nuclei.},

	abstract = {The small angle X-ray scattering (SAXS) technique was used to determine the pore size distributions of some coals from western Canada and their resulting chars. Chars were prepared by pyrolysis at 930 degrees C in nitrogen until no further volatile matter was evolved. The distribution peak of the minerals was identified by acid treatment. Assuming that minerals dispersed in carbonaceous medium are not subject to sintering during pyrolysis, the mineral distribution peak was used as the internal standard to convert each pore size distribution of a coal sample and its char to the same scale. In this way, the changes in pore size distribution that occur during pyrolysis were compared. It was found that for highly reactive chars from low rank coal samples, the total pore volumes increased on pyrolysis. For poorly reactive chars from high rank coals, however, the total pore volumes decreased from their original coal counterparts.},
