Our
latest acquisition is the flat-coil probe built by Bruker U.S.A for experiments
with biological samples oriented on glass plates. This probe features Bruker's
E-free design for proton decoupling, and has four r.f. channels, 1H/13C/(15N,
31P). The flat-coil size is 7x3 mm. The probe has recently been tested in
PISEMA experiments with 15N-labeled N-acetyl valine, NAV (shown, experiments
performed by M. Monette, Bruker). Polarization Inversion Spin Exchange at
the Magic Angle (PISEMA) technique finds applications in correlation experiments
and is used for accurate measurements of chemical shift and heteronuclear
dipolar interactions (see Annual Reports on NMR Spectroscopy, 2004,
volume 52, p.1-52).

Annual ReportNovember 22, 2008
2007-2008 Annual Report of the 900 NMR Facility is posted online and is available for download. We will start mailing printed copies shortly.
We would like to take this opportunity to thank those who contributed to this report, as well as our partners and funding agencies for their continuing support.
Two
new NMR probes have been recently added to a growing array of tools at the
900 Facility. The previously announced 4 mm CP/MAS 1H/13C/15N probe has passed
its first tests in mapping 13C-15N REDOR distances, as in this experiment
with Glycine performed by Eric Ye (the 900 Facility).
The second probe is a flat-coil E-free probe built by Bruker U.S.A for experiments
with biological samples oriented on glass plates. The probe is equipped with
four r.f. channels, 1H/13C/15N/31P and is scheduled for testing. All probes
from our unique probe collection are readily available
to the Facility users. Please enquire.
This recent paper describes the design and security features of the SpectroGrid remote access system.

It
has been three years since the 900 Instrument is up and running. Quite busy
and successful years too ! We would like to congratulate our users, partners,
and sponsors with this milestone.
You
will find the 900 installation pictures here.
Our congratulations to Eric Ye, who successfully defended his Ph.D. thesis "Studies of Proton Conductors Based on Nafion and Sulfonated Polyether Ether Ketone (S-PEEK) Using High-resolution Solid State NMR" (McMaster University, research supervisor Gillian Goward).
See some of Eric's publications here.

Designation
of the 900 NMR Facility as a National Facility has now been officially
confirmed by the Canada Foundation for Innovation (CFI). Congratulations to
all our users and clients from 18 Canadian universities and four NRC Institutes
in eight provinces across the country (British Columbia, Alberta, Saskatchewan,
Manitoba, Ontario, Quebec, Nova Scotia and New Brunswick) who have contributed
to this success !
Fulfilling
our promise to the Canadian NMR community, we are pleased to announce that
the 900 MHz NMR instrument is now remotely- accessible from virtually everywhere
in Canada. This exciting for many of our users option has become reality as
a part of the SpectroGrid project developed and supported by the National
Research Council Canada (more).

The 900 Steering Committee is very glad to announce a travel support program for researchers visiting the 900 Facility. Starting in October students and young scientists from Canadian Universities may apply for a travel stipend towards full or partial reimbursement of their travel expenses. All requests should be submitted by a supervisor in advance of the trip and include a cost estimate. Requests should be forwarded to the Facility manager for review and approval by the Steering Committee.
Please also note that the 900 NMR user policies have been revised. Use only this latest version for your reference, in particular regarding the proper acknowledgement of the Facility.

Encyclopedia has arrived !

Another milestone for our Facility ! Our first publication in the Journal of Magnetic Resonance. Congratulations to Darren Brouwer and John Ripmeester from SIMS NRC on this achievement (see "publications"). In his work on the 900 Darren is developing advanced pulse sequences to squeeze the most from 1H NMR spectra of solids. See some of his results on our Featured NMR Spectra page.
November 21, 2006
We are very proud to announce total three new research papers featuring results from the 900 instrument, all accepted for publication in Journal of Physical Chemistry (see "publications") :
The first paper is by Dave Bryce and Samyuktha Adiga from the University of Ottawa and their colleagues from the Washington University School of Medicine on cation-pi interactions studied via solid-state 23Na NMR. These interactions are important for example in biomolecular recognition by proteins, peptide stability, and protein-DNA interactions. Authors have brilliantly demonstrated usefulness of 23Na NMR at high magnetic fields to study such interactions.
The second paper is by Igor' Moudrakovski and John Ripmeester from SIMS NRC. They have performed a systematic 39K NMR study of solid potassium salts and underlying effects of quadrupolar and chemical shift tensors. No doubt this paper will be a very useful reference for everyone working with potassium, would it be in biological assemblies and membranes, or in catalytic systems for partial oxidation.
The third paper is also from the University of Ottawa by Dave Bryce and Gregory Sward. There they report new 35Cl and 37Cl NMR data for a variety of solid amino acid hydrochlorides. Not only of general interest for any solid-state NMR researcher, these new results will have significant impact on future studies of chloride ion channels.
Our sincere congratulations !
