"Given the Halbach Array type-NMR device has been proved to be effective, it is time to start looking a bit harder at the rest of the device, next step, the rf transistor/detector and the probe."



A 1H/19F Minicoil NMR Probe for solid-state NMR: Application to 5-fluoroindoles
Graether,Steffen;DeVries,Jeffrey;McDonald,Robert;Rakovszky,Melissa;Sykes,Brian
Journal of Magnetic Resonance
2006, Vol.178(1), pp.65-71
doi:10.1016/j.jmr.2005.08.010




Abstract
We show that it is feasible to use a minicoil for solid-state 19F 1H NMR experiments that has short pulse widths, good RF homogeneity, and excellent signal-to-noise for small samples while using low power amplifiers typical to liquid-state NMR. The closely spaced resonant frequencies of 1H and 19F and the ubiquitous use of fluorine in modern plastics and electronic components present two major challenges in the design of a high-sensitivity, high-field 1H/19F probe. Through the selection of specific components, circuit design, and pulse sequence, we were able to build a probe that has low 19F background and excellent separation of 1H and 19F signals. We determine the principle components of the chemical shift anisotropy tensor of 5-fluoroindole-3-acetic acid (5FIAA) and 5-fluorotryptophan. We also solve the crystal structure of 5FIAA, determine the orientation dependence of the chemical shift of a single crystal of 5FIAA, and predict the 19F chemical shift based on the orientation of the fluorine in the crystal. The results show that this 1H/19F probe is suitable for solid-state NMR experiments with low amounts of biological molecules that have been labeled with 19F.

European Journal of Medicinal Chemistry
1987, Volume 22, Issue 5, Pages 417-419

Abstract
Monophenolic 2-amino-1-indanones and 2-amino-1-tetralones having various substituents on the nitrogen atom were prepared and their activities in vitro on D1 and D2 dopaminergic receptors were assayed. All compounds were inactive in binding assays and this inactivity is discussed.

A Pending Request from August by headstrong

   
   
Can i ask a Russian paper? Below is the data about this paper that originally posted by Nomud in DF.
"The former needs no comment, latter does.While researching reduction methods of benzylic-OH
came across a vague USSR abstact to reduce said group.This method while the description
was very vague and my Russian sucks seems worlds safer
than the former methods so popular in abstraction
the orig. USSR abstract gave ref. from 1800's german ref. as remembered reduction carried out in
 either MeOH or EtOH w/ either H2SO4 or formic acid with copious quantity of ZnCl2 to
benzylic-OH molar ratio around 10-15:1 to BzCH2OH ouch.

Journal Gen chemistry USSR 29, 620 (1959) should be in english here,
 but this paper cites 1800's german lit source as their ref..If someone can post orig. article,
and cited german ref."
It sounds too good to be true, hope that procedure not only for tertiary benzylic alcohol.
Thanks in advance.

Thanks so much java.

Could someone get the book Hairy Roots by John W. Doran isbn: 9789057021176, kind of a tall order but you never know.

"I must add my thanks to that of Java, we have several very efficient and superbly effective responders, without whom a lot of information would still be missing. We have accessed some information the collective has never had, we have retrieved a lot more that was lost. Funny thing, for such a "small" forum, I suspect it may have the highest signal-to-noise ratio I've ever encountered. Please keep up the assistance, it is immensely appreciated."

A Radio-Frequency Source Using Direct Digital Synthesis and Field Programmable Gate Array for Nuclear Magnetic Resonance.
Liang,X;Weimin,W
Rev. Sci. Instrum.
2009, Vol.80(12),  pp.124703-124703-4
DOI: 10.1063/1.3271379




Abstract
A radio-frequency (rf) source for nuclear magnetic resonance (NMR) is described. With the application of direct digital synthesis (DDS), the rf source has the ability to yield rf pulses with short switching time and high resolution in frequency and phase. To facilitate the generation of a soft pulse, a field programmable gate array (FPGA) cooperating with a pulse programmer is used as the auxiliary controller of the DDS chip. Triggered by the pulse programmer, the FPGA automatically controls the DDS to generate soft pulse according to predefined parameters, and the operation mode of the pulse programmer is optimized. The rf source is suitable for being used as transmitter in low-field (<1 T) NMR applications, for example, magnetic resonance imaging and relaxation measurement. As a compact and low-cost module, the rf source is of general use for constructing low-field NMR spectrometer.

DOI: 10.1055/s-2003-42485



Abstract
Zn powder is found to catalyze the Friedel-Crafts acylation of aromatic compounds with acyl halides efficiently under microwave irradiation in solvent-free conditions. Activated substrates undergo acylation predominantly at the para-position. The Zn powder can be re-used up to six times after simple washing with diethyl ether and dilute HCl.

Key words
Friedel-Crafts acylation - zinc powder - aromatic compounds - solvent-free conditions - microwave activation

Meas. Sci.
1990, Vol.1(7),  pp.647
DOI: 10.1088/0957-0233/1/7/019




Abstract
A data acquisition card is designed and constructed for the Amstrad PC 1512, a low-cost IBM compatible microcomputer. This card is installed in the expansion slot of the microcomputer and the software necessary for nuclear magnetic resonance data acquisition and analysis is developed. This system generates the pulse sequences necessary for a nuclear magnetic resonance pulse spectrometer and acquires data from the free-induction-decay signal for further analysis. The generation of the timing pulses and the capturing of the free-induction-decay signal are done with the help of an assembly language source program.

ODIN - Object-Oriented Development Interface for NMR
Jochimsen,Thies;von Mengershausen,Michael
J. Mag. Res.
2004, Volume 170(1),  pp.67-78
DOI: 10.1016/j.jmr.2004.05.021



Abstract
A cross-platform development environment for nuclear magnetic resonance (NMR) experiments is presented. It allows rapid prototyping of new pulse sequences and provides a common programming interface for different system types. With this object-oriented interface implemented in C++, the programmer is capable of writing applications to control an experiment that can be executed on different measurement devices, even from different manufacturers, without the need to modify the source code. Due to the clear design of the software, new pulse sequences can be created, tested, and executed within a short time. To post-process the acquired data, an interface to well-known numerical libraries is part of the framework. This allows a transparent integration of the data processing instructions into the measurement module. The software focuses mainly on NMR imaging, but can also be used with limitations for spectroscopic experiments. To demonstrate the capabilities of the framework, results of the same experiment, carried out on two NMR imaging systems from different manufacturers are shown and compared with the results of a simulation.

Online Low-Field 1H NMR Spectroscopy: Monitoring of Emulsion Polymerization of Butyl Acrylate

Macromolecules
2010, Vol.43(13),  pp.5561–5568
DOI: 10.1021/ma1006599



Abstract
The emulsion polymerization of butyl acrylate was monitored by online nuclear magnetic resonance spectroscopy at 20 MHz 1H frequency. The reaction progress could be followed, monitoring the conversion of the reactant time-resolved without any need of sample preparation. Experimental data were analyzed with kinetic models for free-radical polymerization. The data comprised the polymerization rate in seeded batch emulsion polymerizations of butyl acrylate with doubly deionized water and D2O as solvent. The polymerization rate versus conversion curve behaves compatible with the three rate intervals model, typically observed in emulsion polymerizations. Zero?one kinetics explains the experimental results appropriately, leading to the determination of entry and termination rate coefficients.
