High-stroke silicon-on-insulator MEMS nanopositioner: control design for non-raster scan atomic force microscopy.

The Review of scientific instruments

Maroufi M, Fowler AG, Bazaei A, Moheimani SO.
PMID: 25725850
Rev Sci Instrum. 2015 Feb;86(2):023705. doi: 10.1063/1.4907908.

A 2-degree of freedom microelectromechanical systems nanopositioner designed for on-chip atomic force microscopy (AFM) is presented. The device is fabricated using a silicon-on-insulator-based process and is designed as a parallel kinematic mechanism. It contains a central scan table and...

Synthesis of 18pi annulenic fluorofullerenes from tertiary carbanions: size matters!.

Organic & biomolecular chemistry

Burley GA, Avent AG, Boltalina OV, Drewello T, Goldt IV, Marcaccio M, Paolucci F, Paolucci D, Street JM, Taylor R.
PMID: 12945788
Org Biomol Chem. 2003 Jun 07;1(11):2015-23. doi: 10.1039/b301820m.

A range of tertiary carbanions XCH(CO2Et)2 of differing sizes have been reacted with C60F18 to assess the steric effect of X on the position of nucleophilic substitution. For X = CO2Et, NO2, P(O)(OMe)2, SO2CH2Ph, the all trans annulenes (trannulenes)...

Reference potential calibration and voltammetry at macrodisk electrodes of metallocene derivatives in the ionic liquid [bmim][PF6].

Analytical chemistry

Hultgren VM, Mariotti AW, Bond AM, Wedd AG.
PMID: 12141676
Anal Chem. 2002 Jul 01;74(13):3151-6. doi: 10.1021/ac015729k.

Reference potential scales are not generally available in ionic liquids. Consequently, comparison of data with those obtained in conventional solvent (electrolyte) media is not possible. The process [Co(Cp)2](+/0) (Co(Cp)2 = cobaltocene) has been studied at gold, glassy carbon and...

Formation of novel sulfur-containing C60F16 cycloadducts between tetrathiafulvalene and C60F18; a unique six-electron cycloaddition of a fullerene involving F2 loss.

Chemistry (Weinheim an der Bergstrasse, Germany)

PMID: 12740847
Chemistry. 2003 May 09;9(9):2008-12. doi: 10.1002/chem.200204549.

Co-evaporation of solutions of C(60)F(18) and tetrathiafulvalene in toluene produces an unsymmetrical C(60)F(16):tetrathiafulvalene adduct through a unique six-electron cycloaddition involving displacement of two fluorine atoms by a terminal Cdbond;C double bond of the fulvalene. The adduct rearranges into two...

In the first proven SN2' fullerene reaction, both C3 and C1 C60F36 hydrolyse to C1 isomers of C60F35OH that eliminate HF to give epoxides C60F34O; C60F36O oxides are shown to be ethers, and a fourth isomer of C60F36 exists.

Organic & biomolecular chemistry

Avent AG, Abdul-Sada AK, Clare BW, Kepert DL, Street JM, Taylor R.
PMID: 12929643
Org Biomol Chem. 2003 Mar 21;1(6):1026-33. doi: 10.1039/b209760p.

On standing in organic solvents containing traces of water, C3 and C1 isomers of C60F36 slowly convert to C1 isomers of C60F35OH. Both fluorofullerenols eliminate HF during EI mass spectrometry to give C60F34O epoxides, one fullerenol being much less...

Interprofessional education: nursing and occupational therapy - could old rivals integrate?.
