	abstract = {The as-synthesized aluminophosphate framework material AlPO4-14A has a number of unique structural features related to the connectivities in the network of Al and P atoms. One tetrahedral Al atom is present that is linked, via Al-O(H)-Al bonds to two octahedral Al atoms and, consequently to only two P atoms. However, ail Al/P ratio of one is maintained as each of these octahedral Al atoms is connected to five P atoms in addition to the Al-O(H)-Al linkage. This connectivity network means that a framework made up of alternating Al and P atoms cannot be obtained by calcination. A variety of H-1, Al-27, and P-31 solid state NMR experiments have been employed to characterize the AlPO4-14A structure. A fast H-1 MAS experiment showed that the template was in the protonated form and a H-1 {Al-27} TRAPDOR experiment identified the resonance of the {\textquoteright}framework{\textquoteright} proton. The Al-27 and P-31 resonances were completely assigned by the Al-27 -> P-31 INEPT heteronuclear correlation experiment and the quadrupolar parameters of the Al-27 signals determined from the Al-27 MQMAS experiment. Lastly, the complete assignment of both Al-27 and P-31 resonances made it possible to qualitatively determine the location and orientation of the template molecule within the framework from two-dimensional dipolar-based H-1 -> P-31 cross-polarization and H-1 -> Al-27 TEDOR heteronuclear correlation experiments. The data from these experiments confirm in detail the AlPO4-14A structure and will be useful benchmarks for the investigation of other structures for which diffraction data are limited.

	abstract = {Muonium has been directly detected over a range of temperatures and fields by transverse field muSR in different zeolites: 3A, 13X, USY, ZSM-5, and S-115 (a high-silica form of ZSM-5), as well as in silica gel. The polarizations determined from data at 75 and 150 G were independent of both field and temperature. The amounts of Mu seen vary from similar to20\% to 40\%, with a large missing fraction seen in every case, which may be partly due to slow Mu formation. There is also a fast Mu relaxation rate seen in all samples. This is the first direct observation of Mu in zeolites. (C) 2002 Elsevier Science B.V. All rights reserved.},

	abstract = {In the recent past structure determination of microporous materials has experienced considerable developments in methodology. The FOCUS method: high resolution powder diffraction data used for direct method structure solution in combination with crystal chemistry based modelling. The models are retrieved from electron density maps calculated in direct method runs, energy minimized and checked through for realistic angles and distances values. The SUM-TF method: diffraction patterns at moderate resolution analysed with direct methods using a modified tangent formula which includes Patterson information for the structure solving. In this way the atomic resolution criterion for direct methods is bypassed. This overview gives a summary of the structures successfully solved using these new techniques.
