Ultrawideline dynamic nuclear polarization (DNP)-enhanced (195)Pt solid-state NMR (SSNMR) spectroscopy and theoretical calculations are used to determine the coordination of atomic Pt species supported within the pores of metal-organic frameworks (MOFs). The (195)Pt SSNMR spectra, with breadths reaching 10 000 ppm, were obtained by combining DNP with broadbanded cross-polarization and CPMG acqu...

A route for the fabrication of porous inorganic hollow fibers with high surface-area-to-volume ratio that avoids harmful solvents is presented. The approach is based on bio-ionic gelation of an aqueous mixture of inorganic particles and sodium alginate during wet spinning. In a subsequent thermal treatment, the bio-organic material is removed and the inorganic particles are sintered. The method...

We have used density functional theory methods to investigate the solid-state "magic-angle" spinning (MAS) NMR and single-crystal NMR/ENDOR spectra of paramagnetic organometallic complexes and metalloporphyrins. The solid-state MAS NMR chemical shifts (including both diamagnetic and hyperfine contributions) are predicted with a slope of 1.007 and an R2 = 0.967, corresponding to a 28 ppm (or 6.3...

Article history: Received 12 August 2009 I study the slow adoption of ring spinning in Great Britain's cotton industry at the end of the 19th century, which has been used as evidence of British entrepreneurs' declining efficiency and conservatism (Musson, 1959; Aldcroft, 1964; Lazonick, 1981, 1981b). To this purpose I use firm-level data from all of Lancashire's cotton firms over several years....
