Bel Jour: a discipline-specific portal to periodicals
No full textConvenient, subject-based access to current periodicals can be difficult to achieve in today’s mixed and changing journals environment. This paper describes the creation of a web-accessible database of journals in business and economics, using Microsoft Access and ColdFusion. Bel Jour, the Business and Economics Locator for Journals at Rutgers, provides value-added descriptive information about a specific subject-based journal collection, along with convenient access to content from this collection. Although the actual journal collection is dispersed among many physical and online locations, Bel Jour provides a single, virtual point of access for researchers in the discipline.Published in print as Womack, Ryan. “Bel Jour: a discipline-specific portal to periodicals.” Information Technology and Libraries, Volume 21, Number 2, June 2002, pp. 81-86.Peer reviewe

Perspective on the Hyperpolarisation Technique Signal Amplification by Reversible Exchange (SABRE) in NMR Spectroscopy and MR Imaging
No full textSignal amplification by reversible exchange (SABRE) is a para-hydrogen-based technique that utilises a metal complex, normally centred on iridium, to propagate polarisation from para-hydrogen-derived hydride ligands to spin-1/2 nuclei located in a bound substrate. To date, substrates possessing 1 H, 13 C, 15 N, 19 F, 31 P, 29 Si, and 119 Sn nuclei have been polarised by this technique. The exact positioning of these nuclei has a direct bearing on the enhancement observed and so substrates must be chosen or synthesised with care in order to maximise polarisation transfer, and hence the resulting enhancement. The chemical composition of the metal complex must be similarly appraised, as the exchange rate of substrates and para-hydrogen is implicated heavily in efficient polarisation transfer. The nature of the polarisation transfer, whether homogenous or heterogeneous, is another important facet to consider here, as is conducting SABRE in water-based systems. This review discusses the physical and theoretical aspects of the SABRE experiment, as well as the applications of the SABRE technique, namely, the detection of analytes at concentrations far below what would be possible with conventional NMR techniques and the collection of hyperpolarised magnetic resonance images. Advances relating to utilising singlet states for SABRE, pulse sequence design and the nature of the polarisation transfer mechanism are also discussed, and the implications for future SABRE-based discoveries highlighted
Rapid SABRE Catalyst Scavenging Using Functionalized Silicas
No full textIn recent years the NMR hyperpolarisation method signal amplification by reversible exchange (SABRE) has been applied to multiple substrates of potential interest for in vivo investigation. Unfortunately, SABRE commonly requires an iridium-containing catalyst that is unsuitable for biomedical applications. This report utilizes inductively coupled plasma-optical emission spectroscopy (ICP-OES) to investigate the potential use of metal scavengers to remove the iridium catalytic species from the solution. The most sensitive iridium emission line at 224.268 nm was used in the analysis. We report the effects of varying functionality, chain length, and scavenger support identity on iridium scavenging efficiency. The impact of varying the quantity of scavenger utilized is reported for the three scavengers with the highest iridium removed from initial investigations: 3-aminopropyl (S1), 3-(imidazole-1-yl)propyl (S4), and 2-(2-pyridyl) (S5) functionalized silica gels. Exposure of an activated SABRE sample (1.6 mg mL−1 of iridium catalyst) to 10 mg of the most promising scavenger (S5) resulted in <1 ppm of iridium being detectable by ICP-OES after 2 min of exposure. We propose that combining the approach described herein with other recently reported approaches, such as catalyst separated-SABRE (CASH-SABRE), would enable the rapid preparation of a biocompatible SABRE hyperpolarized bolus
