Towards ultimate low frequency air-core magnetometer sensitivity.

Scientific reports

Pellicer-Guridi R, Vogel MW, Reutens DC, Vegh V.
PMID: 28536460
Sci Rep. 2017 May 23;7(1):2269. doi: 10.1038/s41598-017-02099-z.

Air-core magnetometers are amongst the most commonly used magnetic field detectors in biomedical instruments. They offer excellent sensitivity, low fabrication complexity and a robust, cost-effective solution. However, air-core magnetometers must be tailored to the specific application to achieve high...

Inorg Chem. 2013 Dec 02;52(23):13719-29. doi: 10.1021/ic402317g. Epub 2013 Nov 15.

We report the synthesis and characterization of a family of cobalt(III) metal precursors, based around cyclopentadienyl and diazabutadiene ligands. The molecular structure of the complexes cyclopentadienyl-Cobalt(III)(N,N'-dicyclohexyl-diazabutadiene) (2c) and cyclopentadienyl-Cobalt(III)(N,N'-dimesityl-diazabutadiene) (2d) are described, as determined by single crystal X-ray diffraction...

PMID: 25584120
ICCAD IEEE ACM Int Conf Comput Aided Des. 2013 Apr;2013:229. doi: 10.1109/FCCM.2013.22.

In this paper we describe an FPGA-based platform for high-performance and low-power simulation of neural microcircuits composed from integrate-and-fire (IAF) neurons. Based on high-level synthesis, our platform uses design templates to map hierarchies of neuron model to logic fabrics....

PMID: 24232837
Planta. 1987 Jan;170(1):20-5. doi: 10.1007/BF00392376.

The contents of free sterols and phospholipids in leaves of wheat, Triticum aestivum L., cultivars of different frost resistances, as well as the physical state of isolated phospholipids in the presence and absence of sterols, were compared before and...

Iron- and Cobalt-Catalyzed Synthesis of Carbene Phosphinidenes.

Angewandte Chemie (International ed. in English)

Pal K, Hemming OB, Day BM, Pugh T, Evans DJ, Layfield RA.
PMID: 26643712
Angew Chem Int Ed Engl. 2016 Jan 26;55(5):1690-3. doi: 10.1002/anie.201508303. Epub 2015 Dec 08.

In the presence of stoichiometric or catalytic amounts of [M{N(SiMe3 )2 }2 ] (M=Fe, Co), N-heterocyclic carbenes (NHCs) react with primary phosphines to give a series of carbene phosphinidenes of the type (NHC)⋅PAr. The formation of (IMe4 )⋅PMes (Mes=mesityl)...

The cation radicals of free base and zinc bacteriochlorin, bacteriochlorophyll, and bacteriopheophytin.

Proceedings of the National Academy of Sciences of the United States of America

Fajer J, Borg DC, Forman A, Felton RH, Dolphin D, Vegh L.
PMID: 16592150
Proc Natl Acad Sci U S A. 1974 Mar;71(3):994-8. doi: 10.1073/pnas.71.3.994.

One-electron oxidation of zinc tetraphenylbacteriochlorin and its metal-free base yielded stable cation radicals. Electron spin resonance hyperfine splittings were assigned by selective deuterations. These results indicate that the protons of the saturated rings of the bacteriochlorins carry large spin...

Effect of frost hardening on lipid and Fatty Acid composition of chloroplast thylakoid membranes in two wheat varieties of contrasting hardiness.
